Why Is Perfect Competition Often Described as the Ideal...

There are different kinds of market structures in this economy. Perfect competition, as one of them, is often described as the ideal market structure, and only treated as a theoretical ideal. If we compare the perfect competition market with other types of market structure, such as monopoly, monopolistic competition, and oligopoly, it will be obvious that the perfect competition is ideal mainly due to the presence of productive and allocative efficiency. In perfect competition, there are a large number of small firms producing homogenous products, in other words, products produced by one firm is identical to the products produced by other firms in the market. There are also a large number of buyers within the market where they have†¦show more content†¦Productive efficiency is achieved when the firm is producing at the minimum point of average cost. Allocative efficiency is achieved when P=MC. As a result, under perfect competition, productive efficiency is achieved in the l ong run, but not in the short-run, when a firm need not be operating at minimum average cost. Productive efficiency is achieved in both the short run and the long run under perfect competition. At the opposite end of the spectrum of the market structures is monopoly, which is a market with a single seller of a good. There are no substitutes for the good; the monopoly is thereby insulated from competition. There are barriers to entry into the market; any barriers to entry into the market will ensure that the firm can sustain its market position into the future. Unlike the perfect competition, the demand curve for monopoly slopes downward, and the demand curve is regarded as showing average revenue as shown in Figure 7. As monopolist has some influence over price, it can make decisions regarding price as well as output. Therefore, the firm is a â€Å"price maker† and can choose a location along the demand curve. The marginal revenue curve (MR) has a fixed relationship with the average revenue curve. MR shares the intercept point on the vertical axis and has exactly twice the slope of AR. MR is zero at the maximum point of the total revenue curve. As with the firm under perfect competition, a monopolist aiming toShow MoreRelatedWhy Is Perfect Competition Often Described as the Ideal Market Structure?

Plato s Theory Of Forms - 1556 Words

Essay 1: Give a careful account of Plato’s theory of Forms as presented in the Phaedo. Plato has an idea that all ideas are merely abstract thoughts, and what we perceive with our senses is actually an imperfect version of these abstract thoughts. This is the basic idea of Plato’s theory of the Forms. To best illustrate the theory of the Forms to others, Plato explains his famous Allegory of the Cave. From the groundwork of the Forms, Plato goes on in Phaedo to argue the immortality of the soul. He intertwines the theory of the Forms with his argument of recollection, and his argument of affinity. In Plato’s allegory of a cave, Plato paints a picture which he uses to help explain his theory of Forms. In the cave, there are prisoners who are locked up and facing a wall. There is a light source (assumed to be a fire or the sun) behind puppets or statues. The positioning of the light source casts a shadow of the puppets on the wall. So, the prisoners can only see the shadows their whole lives. There are also puppeteers moving the puppets around. Behind the prisoners is a an open doorway, leading out of the cave. In this allegory, the puppets or statues represent the non sensuous realm, or the realm of Forms and ideas. The shadows the prisoners see is the realm of the sensuous, or what we see in everyday life. The prisoners represent us, the human condition. We are imprisoned into seeing only a shadow of what is really there. The puppeteers are politicians, or the soffits.Show MoreRelatedPlato s Theory Of Forms Essay1427 Words   |  6 Pages Plato was a standout amongst the most innovative and persuasive masterminds in Western philosophy, his impact all through the historical backdrop of philosophy has been monumental.

Longinus, like Horace, takes a pragmatic position in his literary theory Essay Example For Students

Longinus, like Horace, takes a pragmatic position in his literary theory Essay Longinus, like Horace, takes a pragmatic position in his literary theory. His central question is, what is good writing, and how may it be achieved? His first answer is that good writing partakes of what he calls the sublime. In the classical historical tradition, the sublime implies that man can, in emotions and in language; transcend the limits of the human condition. According to Longinus sublime is a blend of art and nature. Sublimity consists of excellence and distinction in expression. The effect of elevated language is not to persuade others but to entrance them. The effect of persuading the audience is on the artists hand. Irresistible force and mastery as well as the control of the hearer should be all in the poets sphere. In Longinus words à ¢Ã¢â€š ¬Ã‚ ¦a well timed stroke of sublimity scatters everything before it like a thunderbolt, and in a flash reveals the full power of the speaker. An excellent work will uplift our soul. It feels as if the work of art is of our own c reation. Longinus first brings out the defects some poets tend to make when they write poetry. He advice poets to avoid such imperfections like tumidity Pompous style, puerility silly and parenthyrsus misplaces emotions. Tumidity means pomposity in style of writing. He accuses many poets like Gorgias, Callisthenes and Amphicrates for using high flown expressions and confused imagery such as Xerxes the Zeus of the Persians or vultures, animated sepulchers . Puerility is another flaw of poets. This makes the poets write in an ignoble way. There is another mistake some poets make which is parenthyrsus or false sentiment. Writers sometimes get carried away by plots and outbursts of emotions which are not relevant to the matter in hand. Longinus goes on to identify five elements of the sublime: 1 the power of forming great conceptions; 2 vehement and inspired passion; 3 the due formation of figures; 4 noble diction; 5 dignified and elevated composition. He recognizes great art by the presence of great ideas; great ideas, in turn, are conceived of by great men: It is not possible that men with mean and servile ideas and aims prevailing throughout their lives should produce anything that is admirable and worthy of immortality. Great accents we expect to fall from the lips of those whose thoughts are deep and grave. These great men capable of great ideas will also be capable of deep and sincere feeling which transcends the overemotional sentiments of parenthyrsus. The vehement and inspired passion required for the sublime will, like great ideas, spring only from those without mean and servile ideas. The due formation of figures concerns those ways in which elevated thought and feeling may be best expressed: a figure is at its best when the very fact that it is a figure escapes attention. Noble language is that which transports the audience without distracting the audience: it is language which is transparent to the transcendentto  borrow one of Joseph Campbells favorite phrases. Dignified and elevated composition is that which forms important elements into a natural unity. As stated by Longinus good ideas are a mirror image of a good soul. If the mind is corrupted and unprincipled one can not create beautiful art. Such work will not be eternalized. For great ideas Longinus brings out extracts from Homers Iliad. à ¢Ã¢â€š ¬Ã‚ ¦the silence of Ajax in the Calling Up of the Spirits is grand, more sublime than any words. Such good words will be immortalized for ever and Longinus also says he respect Homer for the heroism used in his epics. But he criticizes Homer for creating gods with human defects. Longinus also recognizes when a writer becomes mature in age he tends to lose the spirit of exuberance. In Odyssey Homer has a tendency to bring folks tales into his poetry. Longinus compares Homers late period to the setting sun. Longinus states that both Sappho and Homer used only what they need in a plot which bring out emotions that is important for their work. Longinus studies the devices enhanced by some poets. As worded by Longinus Demosthenes is compared to a thunderbolt, Cicero is like a wide spreading conflagration that rolls on to consume everything far and wide and Plato flows with such a noiseless stream, he none the less achieves grandeur. Twelfth Night Analysis EssayAccording to an internet source Longinus seems to fit squarely into the critical school described by T.S. Eliots Tradition and the Individual Talent. He recommends, as a way to the sublime, the imitation and emulation of previous great poets and writers a move which puts him more clearly into alignment with the Aristotelian view of poetry as an object-in-itself than to the Platonic view of poetryand any other mimetic artas 3x removed from reality. He treats poetry as an agonistic processanticipating Blooms anxiety of influencespeaking of Plato struggling with Homer for the primacy. The poet, in evaluating his work, should ask How would Homer and the other greats have expressed this or that matter? What would they think of my work? How will succeeding ages view my work?

Ruth had a full scholarship to Cornell University and in the movie â€Å"On the Basis of Sex† she is one of the top students. Even after graduating it was hard for Ruth to find a job as a lawyer because of her gender. Eventually she settled for a job as a professor and started to become more involved with gender equality. Ruth even became the founding counsel of ACLU’s womens rights project. After her struggle of personally dealing with gender discrimination, she stood up for herself and was not afraid to fight for what is right and has helped women have a voice. In Ruths closing argument for a case she is working on in the movie, â€Å"On the Basis of Sex† she gives a moving speech talking about why gender equality is important and how it will not ruin the system but improve it. â€Å"We are not asking you to change the country. That has already happened without any courts permission. We are asking you to protect the right of the country to change,† (On the Basis of Sex). This quote stands out because it is talking about how this country is unenviably changing and how the court is trying to keep everything in â€Å"order† by making laws that seem fair but are really actually biased. Ruth is trying convince the judges that change is not a bad thing and people should not be afraid of it. â€Å"Our sons and daughters are barred by law from opportunities based on assumptions about their abilities. We must take these laws on, one by one, for as long as it takes, for their sake,† (On the Basis of Sex). Ruth is referring to a tax law, Section 214, that was biased about gender roles and was her first step into changing the system. Ruth wanted to change to happen and decided to take a slower approach by fighting for one law at a time. If she can convince the court to make a small change then it would open doors for more people to fight and be hopeful of future change. Ruth talks about how the laws are made by assuming each genders ability which is not fair to men or women. A woman should be able to go out and find a job just as easily as a man if she has the same qualifications. Ruth and her husband both graduated with the same degrees yet Ruth was not able to find her dream job as a lawyer while her husband became a successful lawyer. Ruth wanted to fight for future women and men by getting rid of made up gender roles. â€Å"You are being urged to protect the culture and traditions, and morality of an America that no longer exist,† (On the Basis of Sex). This statement is very powerful because she is pointing out how the court and the people in the court are avoiding the changes already happening in America. No matter what the court is trying to keep in place more people are started to realize what is wrong with the laws. Ruth mentions how in law school there were not even bathrooms for women, she then brings up how things have already changed over the years and women are becoming more relevant in these types of environments. â€Å"A generation ago, my students would have been arrested for indecency for wearing the clothes that they do. Sixty-five years ago, it would have been unimaginable that my daughter would aspire to a career. And a hundred years ago, I would not have the right to stand before you. There are a hundred and seventy-eight laws that differentiate on the basis of sex. Count them. The government did the favor of compiling them for you. And while you’re at it, I urge you to read them. They’re obstacles to our children’s aspirations,† (On the Basis of Sex). Ruth is stating that America is changing no matter what and the laws are making it a disadvantage for people to be what they want.By stating all the changes that have already happened, the judges can see that no matter what laws are in place the country will change and evolve and women are becoming more outspoken. In the movie, Ruth has daughter who is motivates her to fight even harder not only for her own rights but for her daughters future. She wants her daughter to grow up in a world where she is not judged by her gender or put at a disadvantage. â€Å"These are laws written by men who think we are privileged to be excused from men’s obligations. But it is not a privilege, it is a cage, and these laws are the bars!† (On the Basis of Sex).   Ruth is describing these laws as a cage because women feel trapped and forced to live a certain life style.   It is not every womens dream to stay at home, cook, clean and raise kids.   Women now want to go out and get an education and have a voice in the world the same as men.   Men back then thought it was a privilege for women to stay home all day and not be out working, when in reality not all little girls dream of becoming a house wife when they grow up.   Women  now have a chance at a career and have opportunities never imagined by previous generations.   Ruth is a woman to admire because she stood up for what is right and took a chance for women everywhere.   I chose her closing argument from the movie because it was a strong statement that was said to male judges.   She put her fear aside and did fought for something she believed in.   I think every  women  should look up to her and feel ashamed for our gender but stand up for it and keep fighting for our rights.

Ch. 15 From the earliest art to the Bronze age Essay - 1

Ch. 15 From the earliest art to the Bronze age - Essay Example The Peliolithic era coincided with Stone Age just before man starting herding and practicing agriculture. Other art forms that were evident in the early Neolithic era were pottery and the construction of megalith and sculpture (Emeritus, Preble and Frank 240-245). In addition, the chapter focuses on Venus of Willendorf, which has also been referred to as the Woman of willendorf. Made between 25,000 and 28,000 BCE, the Woman of Willendorf is the earliest female figure made by humans and was estimated to be about 11.1 centimeter high. The statuette was found by workman Johann Veran in 1908, during an excavation that was conducted by several archaeologists, including Hugo Orbermaier. The statuette was found in Paleolitihic site which was within the vicinity of Willendorf, a small village that was located in Austria. The chapter reveals that the Woman of Willendorf statuette was curved from oolistic limestone which, the archaeologist discovered that it was not from the local area. The statuette also had red orchre tints on its surface. The Woman of Willendorf was seen as a Great Woman Goddess and, the statuette was used by the local people for religious purposes (Emeritus, Preble and Frank 245-246). The art displayed in the Iranian western plateau was temples of massive structures which were constructed in the valley of Mesopotamia. These structures took after the shape of terraced-step pyramids; each of the terraces represented a level that carried stories of the people residing near the plateaus. In fact, the terraces represented the hierarchy on gods at different platforms, and they were erected at the centre of each city, state, taking the shape of the rectangle. It is believed that Ziggurats had a possible inspiration in the construction of the biblical story. The Ziggurats embodied the idea of the â€Å"sacred mountains† that acted as a connection between the heaven and

International Production and Trade - Essay Example As a result of this shift, the United States and much of Western Europe aligned itself with a free market capitalist system whereas the Soviet Union and many parts of the remainder of the world aligned themselves with socialist communism. As a result of this bipolar powershift, the capitalist nations throughout the world realize that one of the only ways to ensure that wealth generation and sustained growth could proliferate was by engaging in a system of capitalism that prized reductions in trade barriers and liberalize nations in trade. The authors further specify the fact that this desire to reduce trade barriers and liberalize trade was ultimately the impetus which helps to give rise to such global entities as GATT, WTO, and the World Bank. Yet rather than each and every nation throughout the world integrating their economies and seeking to provide goods and services with little to no trade barriers, a somewhat different dynamic has been realized. As such, the difference between theory and practice is denoted by the authors with respect to the way in which different trade blocs and trade alliances have developed between the regions and entities throughout the globe. As such, whereas the world might have been previously defined based upon religion and/or ideology, nationality, ethnicity, or any other litany of different qualifiers, the modern world has largely been defined with regards to which nations agreed to a level of unimpeded trade. What this has ultimately affected is a situation through which the world has come to be redefined based upon trade and not based upon many of the other qualifications that had previously constrained and defined the way in which nations have interacted historically. After the collapse of the Soviet Union, this particular trend has only been increasing as more and more nations throughout the globe seek to develop their own trade blocs and alliances in something of a macro form of protectionism. Evidence of this can of course be seen with regards to the way in which the EU, NAFTA, and ASEAN treaties now exists which helped to promote trans regional trade and block the advances of true international liberalism that might otherwise helped to differentiate and grow these respective economies. As a result of this particular approach, the authors discuss the way in which this dynamic shift has encouraged specialization with regards to different industries and regions/economies. Moreover, as well has been generated and regions of the world have come to supply the raw material for finished goods and services in other parts of the world, the authors note the fact that many individuals view this as something of a neo-mercantilist system. Although this is not quite the case, the comparisons are nonetheless existence and should not be dismissed out of hand. As the more wealthy nations, represented by powerful trade alliances and blocs are able to outsource their unskilled labor and raw material extraction to poore r nations, the benefits of these inputs are realized on both entities. Whereas the neo-mercantilist would point to the fact that these nations are being taken advantage

Performance Of Wells Turbine Engineering Essay

Performance Of Wells Turbine Engineering Essay ABSTRACT A Wells turbine has inherent disadvantages in comparison with conventional turbines: relative low efficiency and poor starting characteristics. In this case, the performance of wells turbine is studied on computational analysis by changing aerofoils and providing different angle of incidence for the improvement of the turbines performance. Study is based on analysing the flow of air on turbine using computational analysis at steady condition. 1 INTRODUCTION: The Ozone depletion and global warming have altered the international community and urged the need for more focus on alternative green sources of energy. Ocean wave energy is one of the renewable forms of energy which can be utilized in response to the disturbing prospect of an exhaustible source of energy. Several wave energy devices being studied under many wave energy programs make use of the principle of the oscillating water column (OWC).Potentially; the most successful device used in harnessing on wave energy has been the OWC wave energy converter. The OWC chamber, either floating or bottom standing, with the immersed end opened to the action of the sea. A reciprocating airflow is created by the action of the free surface of the water within the chamber. The conversion of this airflow into mechanical energy may be achieved by a number of devices like:- A. TAPCHAN: The TAPCHAN comprises a gradually narrowing channel with wall heights typically 3 to 5 m above mean water level. The waves enter the wide end of the channel and, as they propagate down the narrowing channel, the wave height is amplified until the wave crests spill over the walls to a reservoir which provides a stable water supply to a conventional low head turbine. The requirements of low tidal range and suitable shoreline limit the world-wide installation of this device. Fig (a) TAPERED CHANNEL[1] (TAPCHAN)http://re.emsd.gov.hk/english/other/marine/images/marine_tech_010_2.gif B. PENDULOR: The PENDULOR device consists of a rectangular box, which is open to the sea at one end. A pendulum flap is hinged over this opening, so that the action of the waves causes it to swing back and forth. This motion is then used to power a hydraulic pump and generator.http://t2.gstatic.com/images?q=tbn:ANd9GcQ7yge9ouptnhszDgsXGA_gCvAXKqbo78BeXZHFFtPB89433p0p Fig (b) PEDULOR [2] C. WELLS TURBINE: The Wells turbine is one of the most suitable air turbines for energy conversion from oscillating air flow. . A schematic view of the OWC device with a Wells turbine is shown in Fig. c. The Wells turbine is an axial flow air turbine. It consists of several symmetrical aerofoil blades set around a hub. As waves Impinge on the device, they cause the water column to rise and fall in the air chamber, which alternately compresses and depressurized the trapped air. This air is allowed to flow to and from the atmosphere through a turbine which drives an electric generator.http://www.aussiestockforums.com/forums/attachment.php?attachmentid=9213stc=1d=1180172232 Fig (c) WELLS TURBINE[3] Fig. 1.1: Schematic of the Three Major shoreline Devices The Wells turbine is a self-rectifying air turbine which is expected to be widely used in wave energy devices with the OWC (Raghunathan, 1995) .It can extract power at low airflow rate, when other turbines would be inefficient. The Wells turbines for wave power conversion have less efficiency. To increase the efficiency is the major quest all over the world, the flow of air through the wells turbine impeller is carried out in this project by using different size impeller and introducing biplane i.e. two rows of symmetrical aerofoil blades. 1.1 WAVE RESOURCEShttp://www.oceanenergy.ie/images/world-map.jpg Fig. 1.2: Global Distribution of Deep Water Wave power levels in kW/m crest length[4] Despite the climate change phenomena, the world resource for wave remains very much as shown in fig. 1.2 by Dr Tom Thorpe [5]. The highest energy waves are concentrated off the western coasts in the 40o-60o latitude range north and south. The power in the wave fronts varies in these areas between 30 and 70kW/m with peaks to 100kW/m in the Atlantic SW of Ireland, the Southern Ocean and off Cape Horn. The capability to supply electricity from this resource is such that, if harnessed appropriately, 10% of the current level of world supply could be provided [4] PERIOD AMPLITUDE POWER DENSITY VELOCITY (m/s) WAVELENGTH (sec) (m) (kW/m) (m) Storm 14 14 1700 23 320 Average 9 3.5 60 15 150 Calm 5.5 0.5 1 9 50 Fig: 1.3 Tthe nautral and technical wave energy resource for the north and west side of the UK[6] The techinical resource is dependent on the nautral conditions like the shape of the rock and location i.e beaches and gullies. The wave energy at calm sea is considered in this project. 1.2 WELLS TURBINE The monoplane Wells turbine i.e. the basic Wells turbine consists of several symmetrical aerofoil blades (NACA four digit series) set around a hub at 90 degrees with respect to the airflow. Since its an invention by Prof. A.A. Wells in 1976, most researchers have focused on improving its efficiency and its range of efficient operation. In fact, compared to other conventional air turbines (e.g. Francis turbine) the Wells turbine has a lower efficiency and a narrow operational region. Nevertheless, it can extract power at low airflow rate, when other turbines would be inefficient. Fig. 1.4: Schematic of the Monoplane Wells Turbine[7] A schematic diagram of a Wells turbine is shown in Fig. 1.4. At first sight the arrangement might seem to be unlikely means of energy conversion. However, once the blades have attained design speed the turbine is capable of producing a time-averaged positive power output from the cyclically reversing airflow with a fairly high efficiency. Wells turbine has low efficiency and poor starting characteristics. The Biplane Wells turbine: Muhammad Mamun in the Study on the Hysteretic Characteristics of the Wells Turbine in a Deep Stall Condition says the pressure drop across a mono-plane Wells turbine above is proportional to the square of the tip speed which has to be limited if transonic effects are to avoided. For wave energy devices which produce significantly larger pressure drops than the limit for a single plane turbine a biplane turbine can be used Fig. 1.5: Schematic of the Biplane Wells [7] It has certain advantages over the conventional monoplane Wells turbine as follows: I. It can operate under high loading. II. It can absorb higher wave power than the monoplane turbine if the diameter and rotational speed of the turbine are kept constant. III. The design speed is lower than that of the monoplane for the same loading. IV. It avoids the use of guide vanes and therefore the turbine would require less maintenance and repairs. [7] 1.3 PRINCIPLE OF OPERATION The principle of operation of Wells turbine is based on the classical aerofoil theory. According to the classical aerofoil theory, an aerofoil which is set at an angle of incidence ÃŽÂ ± in a fluid flow generates a lift force L normal to the free stream. The aerofoil also experiences a drag force D in the direction of the free stream (relative velocity). These lift and drag forces can be resolved into tangential (in the plane of rotation) and axial (normal to the plane of rotation) components FT and FA respectively. Fig. 1.6 Notation for determining lift, drag, and axial and tangential forces on An aerofoil[7] Resulting expression for axial and tangential forces FA = LcosÃŽÂ ± + DsinÃŽÂ ± FT = LsinÃŽÂ ± DcosÃŽÂ ± The axial force is absorbed but the turbine while the tangential force causes the turbine to rotate. For a symmetrical airfoil the direction of tangential force is the same for both positive and negative values of ÃŽÂ ±. Therefore, the direction of rotation of the rotor is independent of airflow direction. 2 AIMS AND OBJECTIVES OF THE PROJECT Simulation of air flow through wells turbine impeller by means of numerical method using a CFD (Computational fluid dynamics) called FLUENT and check the flow process of different parameters and the factors affecting the differences. Since wells turbine is a low efficiency turbine to increase the efficiency of Wells turbine is the other aim. Path followed to meet the requirements is first calculation of efficiency theoretically. Simulating a modified design by using different angle of incidence and making biplane i.e. two rows. Comparing the results of different model and selecting the suitable design. 3 LITERATURE REVIEW: 3.1 Types of CFD PROCESS USED: Commercial CFD code: FLUENT, Star-CD, FLOW-3D, CFX/AEA, etc. Research CFD code: Self-developed Public domain software (PHI3D, HYDRO, and WinpipeD, etc.) Other CFD software includes the Grid generation software (e.g. Gridgen, Gambit) and flow visualization software (e.g. Tecplot, FieldView) Commercial CFD code FLUENT is used in this project. 3.2 General working on CFD Table3.1: CFD working layout The Processes shown in the table 3.1 is divided into pre- process and post- process viz. GAMBIET AND FLUENT General sequence of GAMBIT operations Initial setup Solver selection, Mesh size, Defaults, etc. Geometry creation (ACIS, IGES or Mesh import) Create full geometry Decompose into mesh-able sections Meshing Local meshing: Edge and Boundary layers Global meshing: Face and/or Volume Mesh examination Zone assignment Continuum and Boundary attachment Mesh export General sequence of FLUENT operations Selection of appropriate models. Turbulence, combustion, multiphase, etc. Define material properties Fluid Solid Mixture Prescribe operating conditions Prescribe boundary conditions at all boundaru zones Provide and initial solution Set up solver controls Set up convergence monitors 3.3 Grid generation: Grid generation is one of the key elements in Computational Fluid Dynamics (CFC). It has now become a fairly common tool for use in the numerical solution of partial differential equations on arbitrarily shaped regions. The numerical solution of partial differential equations requires some discretization of the field into a collection of points (nodes) or elemental volumes (cells). The differential equations are approximated by a set of algebraic equations on this collection, and this system of algebraic equations is then solved to produce a set of discrete values which approximates the solution of the partial differential system over the field. The practice of discretizing the physical domain into a finite number of elements is called as grid generation. 3.4 Grid topologies Generally, the governing equations may be transformed into finite element, finite difference, or finite volume equations. The cell types supported by FLUENT are followed as: triangular and quadrilateral cells in 2D are accepted, and in 3D, tetrahedral, hexahedral, wedge, and pyramid cells can be used FIG3.2: Different types of grids Structured versus Unstructured Grids The section presents a brief description of grid generation. The grid generation techniques available at present fall into two categories, namely: a) structured grid generation and b) unstructured grid generation. The structured grid generation techniques are based on the transformation of the complex physical domain into a simple computational domain, which is often chosen to be rectangular in shape (quadrilateral and hexahedron). The unstructured grid generations have been used with FEM (finite element method) procedure only, whereas structured grids have general applicability.[7] . 3.5 Types of structured grid In FLUENT, both single-block and multi-block structured meshes are acceptable, as well as hybrid meshes containing quadrilateral and triangular or hexahedral, tetrahedral, pyramid, and wedge cells Multiple Block Sometimes, it is possible to combine several structured computational meshes together to fit the physical domain. Multi- locking has the advantage of the speed of a structured solver, without as many mapping constraints apparent in single block meshes. Single Block In this technique, one computational grid is mapped to fit the whole physical domain. For even moderately complex shapes, it may be practically impossible to define a transformation which will map the outer surface of the computational domain to the required physical shape, while ensuring that the resulting grid has desirable attributes of smoothness.[7] 3.6 Mesh quality The quality of mesh plays a significant role in the accuracy and stability of the numerical simulations. The attributes associated with mesh quality are density of node, cell shape, smoothness and flow-field dependency. In many cases, poor resolution in critical regions can dramatically alter the flow characteristics. 3.7 The Capabilities of FLUENT This section provides a brief introduction to FLUENT and an explanation of its capabilities [10].FLUENT used in this project is a commercial code and a state-of-the-art computer program for modelling single and multiphase flows, heat and mass transfer, chemical reaction phenomena, and etc. in complex geometries. This code includes following components; FLUENT, the flow solver; GAMBIT, the pre-processor for geometry modelling and mesh generation; pre-PD, and etc. FLUENT solver utilizes a finite-volume, pressure-based, multiphase space marching method (SIMPLE algorithm), for solving the governing integral equations for conservation of mass and momentum, and for energy and other scalars such as turbulence and chemical species. It has the following modelling capabilities: à ¢Ã¢â€š ¬Ã‚ ¢ Flows in 2D or 3D geometries using triangular/tetrahedral, quadrilateral/hexahedral, or mixed (hybrid) grids that include prisms (wedges) or pyramids à ¢Ã¢â€š ¬Ã‚ ¢ In compressible or compressible flows à ¢Ã¢â€š ¬Ã‚ ¢ Steady-state or transient analysis à ¢Ã¢â€š ¬Ã‚ ¢ Laminar and turbulent flows à ¢Ã¢â€š ¬Ã‚ ¢ Newtonian or non-Newtonian flow à ¢Ã¢â€š ¬Ã‚ ¢ Convective heat transfer, including natural or forced convection à ¢Ã¢â€š ¬Ã‚ ¢ Coupled conduction/convective heat transfer à ¢Ã¢â€š ¬Ã‚ ¢ Radiation heat transfer à ¢Ã¢â€š ¬Ã‚ ¢ Inertial (stationary) or non-inertial (rotating) reference frame models à ¢Ã¢â€š ¬Ã‚ ¢ Multiple moving reference frames, including sliding mesh interfaces and mixing planes for rotor/stator interaction modelling à ¢Ã¢â€š ¬Ã‚ ¢ Chemical species mixing and reaction, including combustion sub models and surface deposition reaction models à ¢Ã¢â€š ¬Ã‚ ¢ Arbitrary volumetric sources of heat, mass, momentum, turbulence, and chemical species à ¢Ã¢â€š ¬Ã‚ ¢ Flow through porous media à ¢Ã¢â€š ¬Ã‚ ¢ One-dimensional fan/heat-exchanger performance models à ¢Ã¢â€š ¬Ã‚ ¢ Two-phase flows, including cavitations à ¢Ã¢â€š ¬Ã‚ ¢ Free-surface flows with complex surface shapes FLUENT can provides a number of boundary conditions, including: à ¢Ã¢â€š ¬Ã‚ ¢ Velocity or Pressure Driven Inlets/Outlets à ¢Ã¢â€š ¬Ã‚ ¢ Stationary or Moving Walls, with or without Friction à ¢Ã¢â€š ¬Ã‚ ¢ Periodic Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Symmetry Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Pressure Far-filed Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Outflow Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Inlet/Outlet Vent Boundary Conditions à ¢Ã¢â€š ¬Ã‚ ¢ Intake/Exhaust Fan Boundary Conditions As the Well turbine has a complex geometry for modelling, a large number of modelling capabilities are required of the CFD code for the turbine. FLUENT can incorporates all of these capabilities, and is most suitable for modelling the Wells turbine.[10] 4 ANALYSIS OF TASK 4.1 Theoretical calculation: The dimension used in this project is of prototype obtained from others experimental work, the model is designed and simulated by using the two different models shown in the table below. a [8] b[9] Table 4.1 Dimension of wells turbine The theoretical calculation of efficiency is done using the above two different dimension, the method used to calculate the efficiency is shown below.

Usig a Trendline option in Microsoft Excel an equation of direct relation between angle of attack and efficiency is obtained. The equation shown in the graph is a sixth order equation which is difficult to differentiate to obtained the angle at which the efficiency will be maximum,so a 2nd order equation is obtained from trendline option. Differentiating the equation gives the value of an angle at which the efficiency is max. From this procedure 12 degree is the calculated angle obtained at which the efficiency is max.

Fig 4.6: Impeller of wells turbine Creating a model using gambiet and then meshing the geometry for which meshing size is selected based on the Reynolds number. Since the Reynolds number lies in the transational flow at the angle in which the efficiency is maximum,using turbulence boundary layer formula: à °Ã‚ Ã¢â‚¬ ºÃ¢â‚¬ ¦ =0.00269 The thicknes of boundary layer is 0.003 m. The mesh size comes to be 0.001m to get three elements in one layer to get fine meshing. In case of 3-Dimensional model the mesh elemet used is Tet/Hybrid. Checking the meshing quality the Aspect Ratio lies between 1 to 4. Boundary conditions is given for impeller is moving wall and interfaces is decided so that the fluid can be rotated within this volume. The mesh is exported for post processing in Fluent 4.3 Fluent (Post Processing) Steps used in fluent is as follows: Step 1 Opening the case file Step 2 Defining the grid interfaces Step 3 Grid check Step 4 Defining model as viscous and using K-epsilon (2 equation ) Step 5 Defining boundary condition In boundary condition fluid within the impeller is made to rotate at 40 rads/sec. The impeller is a moving wall rotating relative to cell zone at 0 rads/sec. Inlet velocity is 10 m/sec and the turbulence method selected is intensity and hydraulic cylinder.

The Constant

â€Å"The Constant† is an episode from the fourth of six seasons of the critically acclaimed drama series, Lost, which aired on the American Broadcasting Company between September 2004 and May 2010. The initial opening of Lost begins with a plane crash on a deserted island. Throughout the extent of the series, the survivors of the crash are challenged by fear of the unknown island, desperation for food and water, and most importantly, each other.The deserted island in which the series takes place is not Just any island – that is, it is not able to be found by anyone living outside of it – and once the characters are iving there, they essentially have no way out. They are trapped, and can be found by no one. There is a mysterious group of civilians who are called â€Å"The Others† living on the island when Oceanic flight 81 5 crashes.This group of â€Å"Others† is part of the scientific research organization called the â€Å"Dharma Initiative† which has placed several stations at differing locations on the island, a sequence of numbers that seems to appear in lives of characters from the past, present, and future and personal connections among characters of which they are unaware. The main character of focus in the episode â€Å"The Constant† is Desmond Hume, a man who was captured on the island long before Oceanic flight 81 5 crashed.He is residing in the hatch, an underground room that supposedly releases an electromagnetic charge to prevent a large buildup of electromagnetic energy. Desmond is forced by the means of survival to punch numbers into a computer for several years, told that if he refuses to punch the numbers the world as he knows it will come to an end. At one point, Desmond misses the timer on the computer and does not punch in the numbers on time. As a result, a massive electromagnetic field is released, attracting all metal object to the hatch, and consequentially causing Oceanic flight 815 to cr ash on the island.Desmond manages to stop and therefore safely disperse the electromagnetism by punching the code into the computer after it hits zero, but is too late to prevent the plane from crashing. By season four, Desmond has already begun to interact with the survivors on the island. In the previous season, Charlie, another survivor from the Oceanic 81 5 crash, had come into contact with Desmond's old girlfriend Penny, and informs Desmond hat a boat which a woman by the name of Naomi had brought to the island, did not in fact belong to Penny as Naomi had claimed.Charlie then drowns, leaving Desmond with several unanswered questions. Realizing that Naomi's story is false, Desmond gets on a helicopter with Sayid and Frank to fly to the freight. As the helicopter flies through a storm, Desmond begins to have flashbacks of a familiar reality to his past in 1996 before his life on the island. Shifting back and forth between the past and the present forces Desmond to lose all memor y of the island and Sayid, who is accompanying him on the helicopter.Sayid's concern leads him to contact Daniel Faraday, a man on the island from the freighter, in order to receive some kind of answer to what Desmond is experiencing. Daniel explains that what Desmond is experiencing is actually a form of time travel, and explains to Desmond that when he reverts back to 1996 again, he needs to find Daniel at Oxford University and seek out his help. Here, Daniel performs a test on his pet rat, Eloise, and realizes that Desmond is experiencing a shift of consciousness through time travel.Eloise dies within less than two hours due to the stress to her brain. Daniel informs Desmond that in order to stop the time travel, he must find a ‘constant', something that exists in both 1996 and 2004, the present year. A man strapped to a bed on the freighter by the name of Minkowski is experiencing the same consciousness travel as Desmond but for a longer period of time, and due to the high stress once again caused by the time travel, and the fact that he is unable to find a constant, Minkowski also dies.Frightened, Desmond chooses Penny to be his constant and realizes that in order to fulfill it, he must acquire Penny's phone number and call her from the freighter on December 24, 2004, that day. When Desmond travels back in time once again to 1996, he finds Penny angry and unwilling to speak to him, but explains himself and pleads, saying he needs her phone number and promises not to call for eight years. With the help of Sayid, Desmond uses a phone located on the freighter to call Penny and finds out she has been searching for him for the past three years and she knows about the island.Back on the island, Daniel is searching through his old Journal in which he wrote notes during his time at Oxford, and found an old not he had written, â€Å"If nything goes wrong, Desmond Hume is my constant. † This episode of Lost is an excellent work and is full of several a rtistic and technical hallmarks, some of which are displayed best in the physical and emotional pain Desmond experiences through his time travel between 1996 and 2004. It is obvious throughout the episode until the end that Desmond is having many difficulties controlling his actions due to the fact that he is unable to control when his body switches between the two years.In 1996, he wants to obey his sergeant major's commands when he is in the army, but his consciousness is reacting in ways he is nable to control and he is therefore unable to fulfill any of his responsibilities. Desmond's lack of concentration causes the sergeant major to become so angry that he forces all of the army men to complete extra physical labor. Desmond then leaves to find Daniel Faraday and is again unable to control his conscious actions. He is desperate to find an answer to what is happening to him, and begs Daniel for his help.Desmond witnesses Minkowski die on the freighter due to the same problems he himself is having, and recognizes that if he does not find a constant, he will soon die. When Desmond needs to find Penny to be his constant, he again experiences great frustration because she is initially unwilling to speak to him. However, when she finally gives in and offers Desmond her phone number, Desmond returns to 2004 and immediately calls her to find that she has been searching for him for three years. The episode then presents to the viewer a glimpse of Desmond again in 1996, where he is smiling with gratitude.Harmony is present once Desmond is able to connect with Penny and he is finally able to complete his mission and bring an end to the once unstoppable and unwanted time travelling experiences. The Constant† is not harmonious until this point in the episode, when Desmond realizes that his long-lost love is searching for him and knows about the island. This also represents an element ot ‘Lite and Death' because when Desmond witnesses Minkowski's realizes i t is absolutely necessary to find a constant in order to survive. Both the acting and cinematography in this episode as well as in the entire series is incredible.It is a turning point in the series because it introduced time travel as no longer a question in the world of Lost, but an actual that is definitely possible. This lone answered several questions for the viewer. The episode explained why Desmond lost his memory and why time travel occurs; and new, important characters are introduced as well. Faraday is notably in this episode one of the most important characters because he is able to explain the time travel Desmond is experiencing – and how to stop it – and seems to understand the island better than anyone else.

Project Management Ethical Issues

Melwin Fernandes 200083225 Ethics and Other Management Issues (CIS 485) Duncan Jeffries Project Management Issues What is Project Management? Project management  is the  discipline  of  planning,  organizing, and  managing  resources  to bring about the successful completion of specific project goals and objectives. It is often closely related to program management (Wikipedia). A  project  is a temporary endeavour, undertaken to meet particular goals and objectives, having a defined beginning and end, usually to bring about beneficial change or added value.The temporary nature of projects stands in contrast to, which are repetitive, permanent or semi-permanent functional work to produce products or services. In practice, the  management  of these two systems is often found to be quite different, and as such requires the development of distinct technical skills and the adoption of separate management. The primary challenge of project management is to achieve al l of the project goals  and objectives while honouring the preconceived project constraints. Typical constraints are  scope, time, and  budget.The secondary challenge is to  optimize  the  allocation  and integration of inputs necessary to meet pre-defined objectives. Project Management Approach There are a number of approaches to managing project activities: 1. The Traditional Approach: A traditional phased approach identifies a sequence of steps to be completed. 2. Critical Chain Project Management  (CCPM): It is a method of planning and managing projects that puts more emphasis on the resources (physical and human) needed in order to execute project tasks. . Extreme Programming: It is used in combination with the process modeling  and management principles of  human interaction management. 4. Event chain methodology: It  is another method that complements  critical path method  and  critical chain  project management methodologies. 5. PRINCE2: It   is a structured approach to project management 6. Agile Project Management: It is based on the principles of  human interaction management  are founded on a process view of human collaboration. Project Management Development StageProject development includes a number of elements: five stages and a control system. Regardless of the methodology used, the project development process will have the same major stages. Major stages generally include: ? Initiation ? Planning or development ? Production or execution ? Monitoring and controlling ? Closing The Use and Misuse of Security Technology The misuse of security Technology is one of the main issues in project management. There are a large number of people over the world with very little or no knowledge of security technology which is why certain projects fail.It is a subject which is under discussed but in today's world with relatively low cost, trusted, security technology is readily available and easy to use. It has become a cult ure among people who are not sufficiently educated with the tools of security technology as it is easy to use and has somewhat become a fashionable trend. Some consider technology to be bad for the society. People have to understand that this is only because of its misuse. Technology does not threaten the society, instead it is humans who are the users who use technology to threaten society.So technology itself is not at fault. In the field of information, technology has increased the speed, quantity and communication with co-workers and clients. Advancements in technology have also contributed to work being completed at home which imbalances their work and life. Lost revenue and productivity has become a reason for an increased need and demand for surveillance techniques to monitor employees. Employers have resorted to creating separate computer security departments or divisions to deal with both the internal and external threats.All companies weather large or small have the pressu re to maintain access to critical information in order to run the business and remain competitive. A corporation with hundreds of offices and thousands of employees would have the same pressure of holding critical information as any other small enterprise. A comprehensive data protection solution is going to involve a lot of consideration and contingencies. There are many things can go wrong with your data and you need to be able to respond to them.There are many companies that have opted to purchase solutions from different vendors to fully address these challenges but can be an extremely expensive approach in terms of acquisition, integration and ongoing management costs. There have also been companies who decided the cost is too high and taken their chances, which is an approach that has often resulted in disaster. In the business world today, the loss of important data can cause significant damage and lead to the demise of your business.The same complex and expensive solutions a s the major players in your industry can be cost-prohibitive and unnecessary. Software and People in Project Management The most comprehensive software solution for assessing security of web application, network systems, end point systems and email users is CORE IMPACT Pro. It allows you to take security testing to the next level by safely replicating a broad range of threats to your organization’s sensitive data and critical infrastructure.

Project Management Software It is a key tool in your effort to consistently finish projects on time and within budget. It allows you to do the critical steps Project Managers must do efficiently.There are a number of benefits that Project Management Software can provide such as spotting problems before it’s too late to fix them, optimizing the use of resources so you can finish early, updating the plan each week so you know where you are and updating everyone’s schedule when things change. These are the basic tools that every Project manager should have. Ideally Project Management Software provides managers with time-saving scheduling and analysis tools as well as archive data for use on future projects.Unfortunately Project Management trainings do not include practical skills in using Project Management Software nor the v alue that comes from archiving data on every project. Tasks like scheduling skills to optimize the use of resources to finish as early as possible and project software to identify problems early are best done with Project Management Software which otherwise can waste a considerable amount of time if done manually. With the appropriate Project Management Software, tracking actual performance in terms of hours of work and completion dates builds a database for estimating on the next project.Practically, there are far too many Project Managers who do not have the training or the tools to optimize their schedule or make efficient use of their resources resulting in projects that are guided by guesses. Project Management Software does not make the managers more effective, it just makes them more efficient. Project Management Software does not teach you how to define scope, communicate to the Project sponsor but just lets you accomplish these tasks more efficiently. There are three genera l classes of software available: Statistical Software: To blend in one direction with relational database software such as Oracle or Sybase. †¢ Mathematical Software: MATLAB in the other direction exhibits not only statistical capabilities flowing from code for matrix manipulation, but also optimization and symbolic manipulation useful for statistical purposes. †¢ Visualization Software: Overlaps to some extent with software intended for exploratory data analysis. The user interfaces common range from command line to graphical user interfaces (GUI) to hybrid drag and drop system interfaces.The Statistical Analysis System is available on PC and UNIX based platforms, as well as on mainframe computers. This modern database technique with queries is very easy to use and also accomplished easily. System for Statistical Analysis among the products are for management of large data bases, time series and most classical statistical problems including multivariate analysis, linear m odels (as well as generalized linear models), and clustering; data visualization and plotting.Users with a need to write an applications program using a matrix language, the product SAS/IML provides the ability to program using matrices as objects. SAS is to a large extent an industry standard statistical software package. The demand for students with SAS skills is greater than with skills other than statistical packages. Other statistical of the same general vintage as SAS are MINITAB, BMDP and SPSS. All of these systems began as mainframe systems, but have evolved to smaller scale systems as computing have evolved.MINITAB Inc was formed more than 20 years ago around its flagship product, MINITAB statistical software. MINITAB Statistical Software provides tools to analyze data across a variety of disciplines, and is targeted for users at every level i. e. Scientists, business and industrial users, faculty, and students. It has broadened the scope of its products to include quality control, designed experiments, chemo metrics and an array of general statistics from the original software that helped faculty to teach basic statistics.MINITAB is available on the most widely-used computer platforms, including Windows, DOS, Macintosh, OpenVMS, and UNIX. BMDP features a comprehensive library of over forty statistical routines and has set the standard for high-end statistical analysis software. It has its roots as a bio-medical analysis package from the late 1960’s and each statistical routine has been thoroughly time-tested based on the most advanced algorithms available. Current versions come in several flavors including the BMDP New System Personal Edition.The Professional Edition combines the full suite of BMDP Classic for PCs Release 7 statistics with the powerful data management and front-end data exploration features of the BMDP New System Personal Edition. SPSS Software products run on most models of all major computers and statistical analysis can now be done on the desktop. It is a multinational software company that provides statistical product and service solution for survey research, marketing and sales analysis, quality scientific research, government reporting and education. e SPSS products are a modular system and includes SPSS Professional Statistics, SPSS Advanced Statistics, SPSS Tables, SPSS Trends, SPSS Categories, SPSS CHAID, SPSS LISREL 7, SPSS Developer's Kit, Exact Tests, Teleform, and MapInfo. S-PLUS is a supported extension of the statistical analysis language. It was originally developed at AT;T Bell labs manufactured and supported by the Statistical Sciences Corporation, now a division of Mathsoft. Some of the code has been contributed by prominent individuals from the academic and industrial communities.MATLAB is an interactive computing environment used for scientific and statistical data analysis and visualization. The basic data object in MATLAB is the matrix with functions for basic data analysis and gra phics which are text files that the user can read and adapt for other uses, giving the ability to create their own M-files functions and script files, thus making MATLAB a programming language. The most useful capability is the tool available for visualizing data. It also provides Handle Graphic and there is a considerable amount of contributed MATLAB code available on the internet.The above descriptions of statistical software cover the most well-established commercially available software packages and among them the most extensively used mathematical packages is MATLAB. MINITAB is used in the educational community for introductory courses. BMDP and SPSS find users among communities in which they originated respectively the biomedical and social sciences community. Mainstream applied statisticians tend to use SAS more extensively whereas on the other hand S-plus seems to be a package that is highly regarded among the more research oriented particularly those interested in computati onal statistics.JAVA is a programming language which represents an extension of the World Wide Web capabilities. Basic documents on the web are constructed using HTML, in the sense that once the server delivers the HTML text to the browser, the server has done its job and the static text is interpreted and displayed by the client’s browser. It is a fully distributed, object oriented programming language which allows for creation of a fully interactive web-based system. The data and tools can be sent to the clients’ browser and allows attributes and methods to be linked together.In particular, JAVA allows applets, small applications or subroutines, to be created and transmitted across the web just as static HTML documents are now transmitted. JAVA is intended to be a secure system although security problems do exist with present implementation. However, access to local data is restricted and the JAVA is a secure environment. JAVA has been declared as is related to stati stical data analysis software of the future because it is a practical implementation of a new paradigm in distributed computing.It allows not only the distribution of text and multimedia but also of computing applications and data. It is a response to the enormous popularity of the World Wide Web and under this framework, new statistical, data analytic and other methodologies could be made available and tried out by practitioners in other research fields on their own data and their own computer. Considering the possibility of extending the web in a natural way to acquire data in the same way we acquire human-consumable information, new mechanisms must be sought to provide for the distribution of that data.Best Practices in Project Planning Project managers deal with sponsors who are organizational levels above them and sign their paychecks so Project Managers can’t really argue about the best way to do the project. Having data to quantify the impact of changes and model alter native ways of solving problems gives them much more credibility to give their executives a solid data on which to make their Project decisions rather than having due dates and budgets plucked out of the air.The ethical issue and its consequences, its resolution and its effect on Management In project management, timing is everything. Justifying, Planning, Activating, Controlling and Ending it the right way is the key to a successful Project. It is a disciplined process and a full circle project management that holds every development project together. The project plan, schedule, budget, resources, risk, scope, motivating the players and launching all project activities with communication play a very essential role in project management.It must be constructed in a way that reaches a busy, important audience with the right amount of the right information, a strategic marketing entity in a tight package that must be backed up with well-researched facts and figures that speak directly to the needs, goals, and problem-solving missions of the business. Present them with the business case report and explain it via a well-crafted, well-rehearsed presentation, accompanied by the sponsors. Starting off with a strong solid foundation of research and a creative solution to a business need do the utmost to obtain approval and present justification for the project.Plan Project produces the detailed project plan, project schedule, project organization, and resources. The approved project plan includes understanding the potential risks and the actions that are necessary to manage them. The goal of every project is to drive it to a successful and appropriate conclusion. Controlling a project is imposed not to create a bureaucratic layer, but to ensure that the project proceeds to its planned and scheduled ending. The activity of the project rests with the Project Manager. He controls, monitors, makes decisions ensuring that the project proceeds as planned taking corrective ac tions when necessary.End Project tasks archive the project materials and release the project resources for use on other projects. Conclusion Project management and project planning processes can contribute to an organization's survival and success, while the absence of project management and project planning processes can lead to an organization's demise. This helps in developing the concept for the project, which in turn is used to secure approvals to proceed to the execution phase of a project. Collectively these five steps form the life-cycle phases of project management, and all steps require adequate attention to ensure that a project is adequately managed.Costs, time-frames, quality targets, and other relevant factors are very essential while considering the planning process. Project management ensures that organizations are able to achieve strategic initiatives that extend beyond normal operations through a recognized process, thus aiding organizations in fulfilling strategic objectives such as new product development, process re-engineering, organizational change or financial growth. In conclusion, project management is needed within organizations to support temporary endeavors that create unique products or services.
