Supreme Court Appeals Essay Example | Topics and Well Written Essays - 750 words

Supreme Court Appeals - Essay Example This refers to a court order that requests lower courts to send documents as well as materials pertaining to the case to the Supreme Court. The justices are required to vote to make a decision on whether or not the case has merit before granting a writ of certiorari (Denis et al, 2014). It takes a combination of different criteria for the Court to judge if a case is â€Å"certworthy.† A Circuit Conflict is the first criterion employed by the Supreme Court in granting certiorari. This criterion is used when there is a conflict amongst the lower federal courts concerning an issue. The conflict must be unbearable and current. The reputation of the lower courts involved in the conflict is a variable when employing this criterion (â€Å"Granting Certiorari† par.7). The Importance of a case is also another criterion for judging if a case is ‘certworthy.’ There are a number of different ways that a case can be important enough to attract the Supreme Court’s attention. Similarly, cases that are important to the polity due to the societal and political impact of their resolution, for example Brown v. Board of Education as well as Roe v. Wade, can attract the attention of the Court. As a rule, two other factors influence the Court’s assessment of the importance of a case: breadth, that is, the potential impact on many people as well as the effect on the federal government (â€Å"Granting Certiorari† par.9). Another criterion is the areas of Interest to the Justices of the Supreme Court. Some justices may have a particular hobbyhorse and that can influence on whether the Court awards certiorari or not. Repeatedly, a Justice’s area of interest is determined by personal history as well as geographic origin. For instance, justices from the West might be favor of granting certiorari in water rights cases. Flagrant abuses of justice or flagrant disregard for accepted legal doctrine can sometimes

Power Storage for the National Grid Essay Example | Topics and Well Written Essays - 2250 words

Power Storage for the National Grid - Essay Example There will also be reflections on the current studies that are undergoing to better the power storage in the UK. Major drivers of the UK economy are sectors like the industrial sector and the manufacturing sector. These sectors are very electricity dependent and thus it can be said that electricity is the major driver of the UK economy. In order to ensure that these sectors perform to their utmost efficiency there has to be comprehensive plan as far as the reliability of the Power from the national grid is concerned (Nationalgrid). One major way of guaranteeing the reliability of the power of the national grid is that UK power generators should have a comprehensive power storage plan for the national grid. Even with the very many sources of power like wind, hydro-generation, solar and many others, there is a minimal probability that without having a good storage plan for the national grid can there be reliability as far as power delivery, to the major sectors and also the domestic consumers is concerned will be as effective as it should be (Nationalgrid). One thing that can never go unmentioned are the benefits of storing power, this is due to the numerous good things that come with power that has been stored. Due to the increase in venturing into power production using wind, solar and other green means there is an unusual urge to have a good power storage system. To begin with, national grid power storage if well implemented will be very vital to the UK especially in its bid to achieve the use of greener forms of energy (Nelson 2012). This will guarantee the UK green-energy which will be a milestone since this is the long term goals of the power generators in the UK. Giving so much attention to the greener forms of energy will not only be good news to the environmentalist as far as reduction and minimization of the other environmentally unfriendly forms of power generation are concerned.

Operations Management Essay Example | Topics and Well Written Essays - 2000 words - 3

Operations Management - Essay Example This is mainly due to the extraordinary resilience of Disney during economic difficulties. During the last world recession towards the end of the last decade, Disney reported extraordinary profits for a company during such a tough economic time (chase & Tansik, 1983). In 1992 Disney opened up a new destination in Paris. This was after much analysis and lobbying behind the scenes on the location of the continental Europe branch. Two choices to be considered for the location were Spain and France (Cox, Blackstone & Schleier, 2003). After much analysis and consultation the Disney management decided to locate their new park in Paris France. Despite having unsuitable weather for a park such as a Disney, Paris had all the qualities of a promising market (Flynn, et. Al 1990). Paris was centrally placed in the European continent. This position made it easily accessible to many European citizens eager to experience Disney magic. However as it turned out the project almost watered down to obli vion from its opening and was still performing dismally as late as 2006 (Flynn, et. Al, 1995). Despite various administrative and structural changes in the company Paris Disney park is yet to pick up (Fuchsberg, 1992). This paper is going to look at operation management issues facing Disney, and ways in which through various theoretical explanations the operational problems can be dealt with. The Walt Disney Company founded in 1923 has been credited for its creativity, quality of services and customer oriented service, culminating to high levels of satisfaction in Disney’s clientele. It is this good legacy that prompted Disney to open up a new destination in Paris given the interest it evoked among Europeans (Goldrat, 1984; Gupta et al., 2000). Due to this, the company opened its Paris destination in 1992. Reports from different analysts and the media were highly optimistic that the breakthrough by Disney into the European market would be easy and fast. Policy of the existing Disney parks was projected to aid a lot in the venture (Goldratt, 1992; Goldratt, 1994). These factors and the overall goal of Disney of maximizing exposure and growth worldwide were projected to lead Disney through this period. Disney is also a unique family entertainment park since its services are enjoyable for people (Goldratt, 1997; Goldratt & Cox 1984). In Disney parks, different areas are themed around various areas which contain different attractions and rides which are not as scary as other rides in other parks making them acceptable to people of all ages (Goldratt et al 2000; Heizer & Render 2008). The first detrimental operational issue in Disney is the conformity of its basic setup, despite the huge regional difference in all its parks locations (Hackman & Wageman, 1995; Krajewski, 2007). All its parks from Florida to Tokyo are similar in their basic setup. The setup is basically based on American methods and style which may be alien to international customers. The comp any had opened a Tokyo Disneyland in 1982 which was a great success. The success was reinforced by huge appetite for American themes in Japan. As it would be seen in Europe, different markets portray different appetites for American inspired themes. Europeans were resentful and critical to the introduction of American culture on their continent (Meredith et al 1989). At the opening of Disney Euro the French government played a very big role.

Cases Of Plagiarism And Its Consequences Essay Example | Topics and Well Written Essays - 250 words

Cases Of Plagiarism And Its Consequences - Essay Example Also, it was detected that only the last edition of her book contained a thanksgiving paragraph for Taggart’s in the preface although nothing was written about him in the preface of the first edition. Goodwin had been ousted from the university but the matter was settled very quietly between Goodwin and Taggart with the latter taking no strict action against the accused (Crader). There had been a similar case of plagiarism two years back where Stephen Ambrose, a historian was accused of copying in his book â€Å"The Wild Blue†. He had copied innumerable lines including some entire texts from Thomas Childers â€Å"Wings of Morning†. Some important phrases from Childers book like ‘glittering like mica’ and ‘up, up, up’ has been repeated word by word in â€Å"The Wild Blue† and not been put in quotation marks. Also, he has not done proper referencing and mentioned Childers only in bibliography and footnotes. However, Ambrose escaped the accusation unscathed as Guilders didn’t take any action against him for plagiarism (Barnes). The consequence of plagiarism can be judged only on the basis that whether it was intended or unintended. The above articles indicate that the works done by Ambrose and Goodwin revealed intended plagiarism since the subjects were similar to the books they plagiarized. However, no action was taken against them and such a result sounds unfair as strict actions should be taken against such people. Although Goodwin was ousted from her University, she received several accolades for her work later on from the same university. So it can be said that justice had not been done and created a wrong example for students and authors alike.

Basic Electronics Essay Example for Free

Basic Electronics Essay The p-n junction is a homojunction between a p-type and an n-type semiconductor. It acts as a diode, which can serve in electronics as a rectifier, logic gate, voltage regulator (Zener diode), switching or tuner (varactor diode); and in optoelectronics as a light-emitting diode (LED), laser diode, photodetector, or solar cell. In a relatively simplified view of semiconductor materials, we can envision a semiconductor as having two types of charge carriers-holes and free electrons which travel in opposite directions when the semiconductor is subject to an external electric field, giving rise to a net flow of current in the direction of the electric field. Figure 1 illustrates the concept. A p-n junction consists of a p-type and n-type section of the same semiconductor materials in metallurgical contact. The p-type region has an abundance of holes (majority carriers) and a few mobile electrons (minority carriers); the n-type region has an abundance of mobile electrons and a few holes (Fig. 2). Both charge carriers are in continuous random thermal motion in all directions. Fig. 2. Energy levels and carrier concentrations for a p-type and n-type semiconductor before contact. 1 When a section of p-type material and a section of n-type material are brought in contact to form a pn junction, a number of interesting properties arise. The pn junction forms the basis of the semiconductor diode. Electrons and holes diffuse from areas of high concentration toward areas of low concentration. Thus, electrons diffuse from the n-region to the p-region. , leaving behind positively charged ionized donor atoms. In the p-region the electrons recombine with the abundant holes. Similarly, holes diffuse from the p-region into the n-region, leaving behind negatively charged ionized acceptor atoms. In the n-region the holes recombine with the abundant mobile electrons. This diffusion process does not continue indefinitely, however, because it causes a disruption of the charge balance in the two regions. As a result, a narrow region on both sides of the junction becomes nearly depleted of the mobile charge carriers. This region is called the depletion layer. It contains only the fixed charges (positive ions on the n-side and negative ions on the p-side). The thickness of the depletion layer in each region is inversely proportional to the concentration of dopants in the region. The net effect is that, the depletion region sees a separation of charge, giving rise to an electric field pointing from the n side to the p side. The fixed charges create an electric field in the depletion layer that points from the n-side towards the p-side of the junction. The charge separation therefore causes a contact potential (also known as built-in potential) to exist at the junction. This built-in field obstructs the diffusion of further mobile carriers through the junction region. An equilibrium condition is established that results in a net contact potential difference Vo between the two sides of the depletion layer, with the n-side exhibiting a higher potential than the p-side. This contact potential is typically on the order of a few tenths of a volt and depends on the material (about 0. 5 to 0. 7 V for silicon). The built-in potential provides a lower potential energy for an electron on the n-side relative to the p-side. As a result, the energy bands bend as shown in Fig. 3. In thermal equilibrium there is only a single Fermi function for the entire structure so that the Fermi levels in the p- and the n-regions must align. No net current flows across the junction. The currents associated with the diffusion and built-in field (drift current) cancel for both the electrons and holes. Fig. 3. A p-n junction in the Thermal equilibrium at T gt; 0? K. The depletion-layer, energy-band diagram, and concentrations (on a logarithmic scale) of the mobile electrons n(x) and holes p(x) are shown as a functions of the position x. The built-in potential difference V corresponds to the energy eV where e is the electron charge. 0 0 2 The Biased p-n Junction An externally applied potential will alter the potential difference between the p- and n-regions. This in turn will modify the flow of majority carriers, so that the junction can be used as a â€Å"gate†. If the junction is forward biased by applying a positive voltage V to the p-region (Fig. 4), its potential is increased with respect to the n-region, so that an electric field is produced in a direction opposite to that of the built-in field. The presence of the external bias voltage causes a departure from equilibrium and a misalignment of the Fermi levels in the p- and n-regions, as well as in the depletion layer. The presence of the two Fermi levels in the depletion layer, Efc and Efv represents a state of quasi-equilibrium. Fig. 4. Energy band diagram and carrier concentrations for a forward-biased p-n junction. In effect, then, if one were to connect the two terminals of the p-n junction to form a closed circuit, two currents would be present. First, a small current, called reverse saturation current, is, exists because of the presence of the contact potential and the associated electric field. In addition, it also happens that holes and free electrons with sufficient thermal energy can cross the junction. This current across the junction flows opposite to the reverse saturation current and is called diffusion current. Of course, if a hole from the p side enters, it is quite likely that it will quickly recombine with one of the n-type carriers on the n side. (Fig. 4) The net effect of the forward bias is to reduce the height of the potential-energy hill by an amount eV. The majority carrier current turns out to increase by an exponential factor exp(eV/kT). So that the net current becomes i = isexp(eV/kT) – is, where is is nearly a constant. The excess majority carrier holes and electrons that enter the n and p regions, respectively, become minority carriers and recombine with the local majority carriers. To explain the mechanism of reverse conduction, one needs to visualize the phenomenon of avalanche breakdown. When a very large negative bias is applied to the p-n junction, sufficient energy is imparted to charge carriers that reverse current can flow, well beyond the normal reverse, saturation current. In addition, because of the large electric field, electrons are energized to such levels that if they collide with other charge carriers at a lower energy level, some of their energy is transferred to the carriers with low energy, 4 and these can now contribute to the reverse conduction process, as well. This process is called impact ionization. Now, these new carriers may also have enough energy to energize other lowenergy electrons by impact ionization, so that once a sufficiently high reverse bias is provided, this process of conduction takes place very much like an avalanche: a single electron can ionize several others. Fig. 6. The reverse breakdown region The phenomenon of Zener breakdown is related to avalanche breakdown. It is usually achieved by means of heavily doped regions in the neighbourhood of the metal-semiconductor junction (the ohmic contact) . The high density of charge carriers provides the means for a substantial reverse breakdown current to be sustained at a much lower specific voltage than normal diode, at a nearly constant reverse bias known as the Zener voltage, Vz. This phenomenon is very useful in applications where one would like to hold some load voltage constant for example, in voltage regulators. The response time of a p-n junction to a dynamic (ac) applied voltage is determined by solving the set of differential equations governing the processes of electrons and hole diffusion, drift (under the influence of the built-in and external electric fields), and recombination. These effects are important for determining the speed at which the diode can be operated. They may be conveniently modeled by two capacitances, a junction capacitance and diffusion capacitance, in parallel with an ideal diode. The junction capacitance for the time necessary to change the fixed positive and negative charges stored in the depletion layer when the applied voltage changes. The thickness l of the depletion layer turns out to be proportional to v(Vo-V); it therefore increases under the reverse-bias conditions (negative V) and decreases under the forward-bias conditions (positive V). The junction capacitance C=?A/l (where A is the area of the junction) is therefore inversely proportional to v(VoV). The junction capacitance of a reverse-biased diode is smaller (and the RC response time is therefore shorter) than that of a forward-biased diode. The dependence of C on V is used to make voltage-variable capacitors (varactors). 5 Experiment l(a) : i-v characteristics of a semiconductor diode Procedure Connect the diode according to the circuit diagram as shown in Fig. 8. Fig 8 Vary the voltage V on the power supply between 0-30V. Alternately, the second concept is that the blocking action of an inductor stops the a. c. portion while the d. c. portion passes without much attenuation. Note: For filtering, large capacitance (hundreds to tens of hundreds microfarad) is needed. These are generally electrolytic capacitors, which consist of a repeating sandwich of aluminum sheets and a conducting paste, rolled into a cylinder for miminmun size. The aluminum sheets are polarized to form thin layers of aluminum oxide, a dielectric insulating material. The thinner the the dielectric the higher the capacitance will be.

Design of Automated Biomass Gasifier

Design of Automated Biomass Gasifier ABSTRACT: Biomass gasifiers have found a promising place in renewable energy resource field. Even then, these gasifiers are facing lots of practical difficulties on operational effectiveness due to shortage of man power. So small scale biomass gasifier is fabricate and further the fuel feeding system and switching functions (On/Off Operations) are also changed by means of automation. Bucket conveyors are used to feed the fuel from the reservoir to the pre-storage chamber. The fuel will be fed in equal intervals of time to maintain constant level of fuel in the reactor. The level of the fuel in pre-storage chamber can be checked by means of level sensors. Ignition of the gasifier is also automated using a special ignition set up. All these automations are achieved by using microcontrollers, sensors and limit switches. Keywords: Biomass gasifier, automation, conveyor, microcontrollers. I. INTRODUCTION: Biomass gasifier has evolved in different aspects for more than three decades. Many improvements were made in biomass gasifiers. The rectifications of the flaws found in the gasifiers were sorted out; researched and good results were obtained. Highly efficient biomass gasifiers of different type are in existence at present. Even then there are many problems to overcome in order to make the biomass gasifier further more efficient. The main challenging factors to make the biomass gasifiers highly efficient both cost wise performance wise are as follows, (i)Gasification is quite complex and sensitive process. (ii)Due to the continuous working of the system it requires the repeated refueling. (iii)The removal of residues such as ash and other residues is taking more time.(iv)The formation of producer gas is very easy, but getting the proper state is very difficult.(v)Man power is needed for fueling, igniting and monitoring. Thus resulting in expenditure for safety aspects of human resources, which makes it cost inefficient the system. (vi)Toxicity of producer gas is also a major problem which affects the humans. Amongst all the problems faced, the major problems falls in a category of need for automation. The automation can be done in any type of biomass gasifier. This paper focuses on automating downdraft gasifier in particular. The concept of automation of the biomass gasifier started from the year of 1980 by â€Å"Bil finger industrial automation services†. Various up-gradations and the changes are brought into practice after the middle of 1990’s the automation of gasifier is still being debated for further improvements. A. Automation of the Gasifier Using Microcontroller Energy systems that rely upon biomass fuel are often very complex due to the need for the systems to integrate fuel handling, combustion control, and ash removal. Automation of biomass gasifier is capable of offering a wide range of solutions to suit these needs. These are achieved by utilizing a variety of PLC and SCADA systems at present [1]. Even though PLC SCADA finds a promising place in automation of biomass gasifier [1] there were few disadvantages like highly expensive system for being installed in small scale and medium scale gasification unit skilled workers with deep knowledge about these controlling system are needed. Hence this paper mainly focuses on automation of then gasifier from small scale to large scale unit. This can be achieved by automate the gasifiers using microcontroller. A Microcontroller is a digital computer on a single chip but usually runs for performing a dedicated task. It has CPU, memory, timers, Parallel Serial I/O and peripherals, counters and clock circuit. The primary operation of a microcontroller is performed by using a fixed program that is stored in the ROM. Because of absence of CPU, RAM, ROM, Peripherals all embedded on a single chip in microprocessor, microcontroller has a greater advantage over it. This in turn reduces the size of the application and cost. It consumes low power because it operates at low frequencies and so it is fit for durable application. II. DESIGN OF AUTOMATED GASIFIER: Downdraft gasifier, the upper cylindrical part of gasifier acts as a collection device for wood chips or other biomass fuel [4]. The downdraft gasifier is shown in Fig. 1. Below this cylindrical part of gasifier, there is a radially directed air nozzle that permits air to be drawn in to the raw material, so they become gasified. Before the pyrolyzing of biomass it contacts with atmospheric air, char and support a flame. It rapidly consumes limited air supply for getting richer flame in the pyrolysis zone. At the final stage of pyrolysis zone, the gases consist mostly of C ­o, H2o, Co2 and CH4 [5]. The throat ensures that the gaseous products pass through the hottest zone where most of the tar cracked into gaseous hydrocarbon. Thus produces relatively clean gas. A. Components of gasifier: All the components of downdraft gasifier are designed in soildworks software. Main components of automated downdraft gasifier and their design are described below. 1. Hopper: The purpose of a hopper is to store the biomass for continuous feed to reaction chamber. It is mounted above the reactor of gasifier. The fuel storage hopper is made up of 4mm thick mild steel. The diameter and height of fuel hopper is chosen to be 220mm and 550mm respectively [2]. Round shaped hopper has been chosen to prevent the problem of biomass being stuck. 2. Gasification Zone: This is the main component of gasifier. The main reaction of gasification like oxidation, reduction and distillation takes place in this zone. It is in the shape of vertical convergent and divergent nozzle (from top to bottom direction) and made by 3mm thick mild steel. Upper diameter of divergent section is 100mm and the lower diameter is of 220mm with 100mm height respectively [2]. 3. Outer Cylinder: A cylinder is made to cover the whole gasification assembly. The height and diameter of cylinder are 220mm and 250mm respectively [2]. B. Components of automated gasifier: The components of automated gasifier and their design are described below. 1. Pre-storage chamber: A pre storage chamber is made to store the fuel after the fuel bunker and before the combustion chamber. The height and diameter of cylinder are 200mm and 300mm respectively. 500mm length door frame is placed on the top of cylinder, same 500mm length door frame placed on the bottom of the cylinder. And 250mm outer diameter and 220mm inner diameter flange. 8 holes of 10mm diameter are drilled in the plates to join the hopper and pre-storage chamber with the help of nut and bolts. 2. Pre – Storage Door with lead screw: A pre-storage door with lead screw is placed inside of the door frame. It is used to avoid the atmospheric air to inside the combustion zone. The length, breadth and thickness of door are 300mm, 210mm and 2mm respectively. And the Diameter, Length, Pitch and Thread height of lead screw are 19mm, 320mm, 6mm and 3mm respectively. The Diameter, Length, Pitch and Thread height of box nut are inner diameter- 20mm, outer diameter- 40mm, 35mm, 6mm and 3mm respectively. The door is placed on the top of cylinder, same door frame placed on the bottom of the cylinder. 3. Fuel bunker with conveyor system: A fuel bunker with conveyor is made to store the fuel in the fuel bunker and convey the fuel from fuel bunker to pre-storage chamber (Bucket conveyors were used in the system) [3]. The height, length and width of fuel bunker are 400mm, 450mm and 450mm respectively. And the conveyor is placed inside of the fuel bunker another end is placed on the top of the pre-storage chamber. C. Assembling of automated gasifier: In order to assemble the gasifier components, first of all water tank is placed on the stand and the gasifier is placed inside the tank. Now the pre-storage chamber is placed to top of the hopper and join with the help of nut and bolts. And the fuel bunker with conveyor is placed on the stand one end of the conveyor is fixed inside of the fuel bunker and another side of the conveyor is fixed on the top of the pre-storage tank with help of bolts and nuts. The schematic of automated gasifier unit is shown in fig. 1. Fig.1. Schematic of automated gasifier unit III. COMPONENTS OF CONTROL SYSTEM A. Microcontroller kit: Microcontroller kit is used to control the sequence of operation in this system, like door open close, conveyor system on/off, igniter on/off, blower on/off. These operations are control by according to the sequence of operation. B. Sensors: IR proximity sensor is act as a level sensor. The level of the fuel in pre-storage chamber can be checked by means of level sensors. It can able to sense the nearby objects without any disturbance of the sensed object. It does not have any mechanical parts and also lack of direct contact between sensed object and sensor. So it has high durability and high reliability. C. Motors: Motor is used to drive the conveyor system and door open close operations. These are controlled by microcontroller kit. D. Limit switches: Limit switch is a device which converts mechanical motion in to electric signal. It is operated by physical contact of the object. In this system limit switches are used to control the door open close system. Fig.2. Automated small scale gasifier unit IV. SEQUENCE OF OPERATION Flow chart for sequence of operation Starting process Continuous process If the fuel level comes down in the hopper B. Flow chart description: Starting process: Step 1: set the feeding time interval in the microcontroller kit (using adjustable time regulator). Step 2: press the press button to start the process. Step 3: door 1will be open (using motor limit switch). Step 4: conveyor on fuel is taken from fuel bunker to pre-storage chamber. Step 5: if the fuel attains the maximum level in pre-storage chamber, the conveyor system will be cut off (using sensor to check the level of fuel in pre-storage chamber). Step 6: After these door 1will be close. Step 7: And then door 2 open. The fuel comes from pre-storage chamber to hopper. Step 8: After 25 sec door 2 will be close. Step 9: repeat from step 1 to step 6 another one time for filling the hopper (this repeating process is adjustable in the program. it depends upon the fuel). Step 10: After this process air blower will be on (for creating pressure in the gasification zone). Step 11: After 1min igniter will be on (using automatic igniter). Continuous process: The continuous process will happen for every equal interval. The time interval is adjustable (before start the whole process to set the time interval depends up on the fuel characteristics). Step 1: door 1 open. Step 2: conveyor on fuel is taken from fuel banker to pre-storage chamber. Step 3: if the fuel will be attain maximum level in pre storage. The conveyor system will be cut off. Step 4: door 1 close. Step 5: door 2 open. The fuel comes to hopper. Step 6: After 25 sec door 2 will be close V. CONCLUSION Thus the small scale biomass gasifier was designed and fabricated with automatic controls. This gasifier is initiated with the manual feeding of biomass in the Fuel bunker, set the equal time interval for feeding from fuel bunker to pre-storage chamber and press the push button to start process there after the entire process like fuel feeding system, ignition system, switching functions (On/Off Operations), equal interval of feeding was automated using microcontroller, sensors, limit switches and motors. In future to develop the gasifier in fully automatic mode, to controlling and monitoring the gasifier parameters like temperature, pressure, air flow rate and gas flow rate etc. And also implement this automation in large scale gasfiers.
