Randalls Department Stores Essay Example for Free
Randalls Department Stores Essay Department stores encountered a quandary surrounding their pricing strategies: Should they continue to pursue Every Day Low Pricing strategies coupled with frequent promotions or determine a narrow focus on one or the other? If this is preferable, then which one will reap the biggest benefits for the department store? Competitors were aggressively promoted their established brand promotions with more fervor than ever, and Randallââ¬â¢s was slipping in market dominance. A decision had to be made regarding their pricing policy henceforth. Sales data shows that Every Day Low Pricing was not a preferable strategy. Armed with this knowledge, Randallââ¬â¢s must execute a strategy of changing prices so that there is no confusion with the consumer as to what they can provide: Quality products at consistently low prices. With the elimination of erratic and deeply discounted promotions, Randallââ¬â¢s can begin a new era of consistent sales cycles and profitable returns in a marketing environment which is receptive to this development. #1 ââ¬â There are several distinct advantages to having a more stable and single-level pricing structure. A commitment to this would mean a significant decline in store promotions, but it can be argued that the benefits outweigh the detriments. First, the money that could be saved on largely eliminating sales events accumulates to become a substantial savings pot for the company per year. Secondly, staff members would not be so taxed. Process adjustments borne by the need to honor their guarantee of matching a competitorââ¬â¢s price or paying back the difference if they were to reduce their own requires extra staff that is unnecessary under a stable pricing structure. Another benefit of this strategy is a better inventory turnover ratio. Daily sales can be better predicted and more consistent when the prices to not fluctuate constantly. The cost of residual merchandise to be sold in clearance events at the end of the season is too great when Randallââ¬â¢s is forced to mark these down at even deeper price discounts. This strategic advantage also spawns another: a lesser chance of stockouts. These occurred when a popular item was discounted unnecessarily. The item sold so fast that there were no more left to sell, and those products would have sold regardless without a significant discount. Stockouts can be recognized as revenue forgone when a stable pricing strategy is not implemented. This strategy enables the merchants to be able to dedicate more time and effort to planning their calculated assortment coupled with enhanced service measures. With this comes the success experienced when loyalty to the Randallââ¬â¢s brand is fostered through excellent customer care and superior product presentation established. A store-wide adoption of stable pricing could allow Randallââ¬â¢s to establish a reputation for good value, even in the sea of competitors who continued their fierce promotions. #2 ââ¬â The introduction of a more leveled pricing was largely unsuccessful in many categories, but successful in certain others. The childrenââ¬â¢s clothing department enjoyed a relative price inelastic demand structure. This department enjoyed great success derived from implementing Everyday Low Pricing (EDLP) because the childrenââ¬â¢s merchandise sold carried a lower initial mark-up than formerly and was scarcely promoted at discount prices, if even once a season. The reason EDLP fell flat in many other areas, including jewelry and menââ¬â¢s suits, is because the quality perception of jewelry and suits can be compromised when prices are low from the outset with peripheral promotions going on, consumers anticipate similar discounts on these premier items when they are already at low prices. #3 ââ¬â In the future, Randallââ¬â¢s should try to stabilize prices going forward. This recommendation comes in light of the fact that the only department which thrived under was Childrenââ¬â¢s. But there has already been too much damage done in the perceptual minds of the Randallââ¬â¢s consumers ââ¬â their image has been compromised. The confusion as to whether Randallââ¬â¢s is a more like a Marshallââ¬â¢s or like a JC Pennyââ¬â¢s. With a consistent commitment to lower-level initial mark-ups with few discount promotions, the short surges in revenue seen by sales events will not be as great as the steady revenue brought by the sales of a consumer confident in the quality and competitive price of the Randallââ¬â¢s item. Randallââ¬â¢s canââ¬â¢t follow in the footsteps of high-profile competitor Prescottââ¬â¢s and run aggressive sales events if they are not committed to promoting as hard, if not harder than this competitor. The sales will fall short every time and leave Emily ; Caroline Randall back where they started ââ¬â riding the promotion wave, with the breaker close on the horizon. Please see Appendix A for a detailing of the specific plan of execution for Randallââ¬â¢s executives to changes prices and stabilize them store-wide. With this plan of action, Randallââ¬â¢s can be armed for an era of consistent pricing and steady sales cycles ââ¬â at no expense to their quality perception.

From reading the selected pre-1914 Essay
The Return of the Native (pg 414 ââ¬â 447) near end of novel From reading the above, what do you learn of Hardyââ¬â¢s use of vivid description, dramatic incident and reference to Nineteenth century customs and traditions? Which of the three pieces was your favourite and why? From reading the two extracts and the story, I can see that the main difference in the book is how life is in the book compared to our modern 21st century. People in the 19th century depended very heavily on agriculture and farming especially in ââ¬ËWessexââ¬â¢, where nearly all of Hardyââ¬â¢s novels were set. Wages for agricultural labourers were the lowest in the country in Dorset, averaging out at the equivalent of 37p a week in 1840. Magic and superstition was rife in the 19th century, and many people believedin dark powers. Every village in Wessex was supposed to have their own witch. Magic play a big role in two of the stories which I am studying, ââ¬ËThe Withered Armââ¬â¢, and ââ¬ËThe Return of the Nativeââ¬â¢. People who committed crimes in the 19th century were severely punished. Poachers were transported to Australia to do ââ¬Ëhard labourââ¬â¢, night burglary was punishable by death. Hangings were still very popular in the 19th century and any hanging was an excuse for a ââ¬Ëholidayââ¬â¢. Class systems in the 19th century were very rigid ââ¬â not many people succeeded in moving up to a higher class, but Thomas Hardy was one of the few people who managed to do this. Thomas Hardy uses vivid description in all of his novels and short stories, including the novels which I am studying, in particular ââ¬ËThe Mayor of Casterbridgeââ¬â¢. At the beginning of the chapter, we have an almost cinematic view, as if a camera is zooming in on the three travellers, describing them from afar at first, then in more detail as we begin to see them from closer up. We can almost feel the tension between the two adults, when Hardy says: ââ¬Å"What was really peculiarâ⬠¦ was the perfect silence they preserved. â⬠In ââ¬ËThe Withered Armââ¬â¢, Hardy uses vivid description very effectively when description Rhoda Brookââ¬â¢s vision. He uses words such as: ââ¬Å"â⬠¦ Peered cruellyâ⬠and ââ¬Å"â⬠¦ shockingy distortedâ⬠to imply that Gertrude is mocking her for being cast aside and then Gertrude taking her place as Farmer Lodgeââ¬â¢s wife. This vivid description is also linked to dramatic incident as it is a key chapter in the story, and Hardy uses adjectives to describe Rhodaââ¬â¢s ââ¬Ëdreamââ¬â¢, it makes us feel as though we are actually there, watching this distorted version of Gertrude attacking Rhoda, so Hardyââ¬â¢s descriptions are very effective in this chapter of the book. Also, at the beginning of the story, we learn a lot from the dairy workers in the farm, who gossip. They gossip about Farmer Lodgeââ¬â¢s new wife and they try to guess how old Farmer Lodge is, all the while ignoring Rhoda Brook, Farmer Lodgeââ¬â¢s ex-wife. In ââ¬ËThe Return of the Nativeââ¬â¢, when the superstitious Susan creates a ââ¬Ëvoodooââ¬â¢ doll resembling Eustacia, Hardyââ¬â¢s use of vivid description is effective when Susan thrusts pins in the doll, and then puts it in the firem murmuring the Lordââ¬â¢s Prayer backwards ââ¬â which was a proceed which called for help against an enemy. Magic played a key part in this story; Susan believed that Eustacia was making her son ill, because at the exact moment that he said he was feeling unwell, Eustaciaââ¬â¢s dark shadow crossed the light from her house, but this was just a coincidence. Also, in ââ¬ËThe Return of the Nativeââ¬â¢, when Eustacia falls into the pool of water near weir, Hardy uses pathetic fallacy, which is when events in the natural world mirror what is going on in the human world. In this case, Eustacia is very depressed and unhappy, so the weather is atrochiously stormy, raining and windy. Because, it has rained so much, the pool has created a whirlpool, and Eustacia falls in. To describe the scene more effectively, Hardy uses metaphors such as: ââ¬ËBoiling cauldronââ¬â¢, referring to the whirpool, the current, and emphasising the amount of water in the pool. Hardyââ¬â¢s use of dramatic incident in all three of his stories manage to shape the whole story, especially in ââ¬ËThe Mayor of Casterbridgeââ¬â¢. In think amin the dramatic incident in the extract is when Michael Henchard sells his wife at auction when he becomes drunk. The day after, Michael realises how stupid he has been and vows never to touch another drop of alcohol for however many years as his age. I think this is very effective because the day after Michael sells his wife and baby, he realises that alcohol changed him into something he doesnââ¬â¢t want to be. In ââ¬ËThe Mayor of Casterbridgeââ¬â¢, when Hardy uses dramatic incident, we learn that Hardy builds up suspension before the dramatic climax. When Michael Henchard is trying to sell his wife and baby at auction, nobody will bid the price that he is looking for, then just as Michael is going to withdraw: ââ¬Å"ââ¬ËYes. ââ¬Ë said a voice from the doorway. ââ¬Ë The man in the doorway was in fact, a sailor. He bought Michaelââ¬â¢s wife for five guineas, and she left, leaving us with the impression that she is glad that she has got away from her husband at last. Hardy uses lots of dialect to show exactly how Michael Henchard feels about his current state of affairs: ââ¬Å"The woman is no good to me. Who will have her? â⬠When Michael is trying to sell his wife, Hardy describes Michaelââ¬â¢s distaste for her effectively, and when he finally does sell her, even the rough country people in the tent are surprised that he let his wife and child go without a second glance. In ââ¬ËThe Withered Armââ¬â¢, I think there are two main dramatic incidents: Rhoda Brookââ¬â¢s ââ¬Ëdreamââ¬â¢, and Gertrudeââ¬â¢s turning of her blood, when she sees that the young man who has been hanged is, in fact, Rhodaââ¬â¢s son. When Rhoda has a dream that Gertrude visits her to mock her, Gertrude looks ugly and old. Hardy used use of vivid description works effectively in making us understand that Gertrude has come to mock her because Rhoda has been replaced by her in Farmer Lodgeââ¬â¢s affections. Hardyââ¬â¢s use of verbs work well in this incident, using words such as ââ¬Ëthrustââ¬â¢, ââ¬Ëswungââ¬â¢, and ââ¬Ëpeered cruellyââ¬â¢ to create a feeling of hate between Rhoda and the figure come to visit her at night. The other dramatic incident in ââ¬ËThe Withered Armââ¬â¢ is when Gertrude travels to get her arm cured by holding her arm against a newly hanged manââ¬â¢s neck, who is in fact Rhodaââ¬â¢s son. Hardyââ¬â¢s use of dialect again gives and extra depth to the story, when Rhoda walks in when Gertrudeââ¬â¢s blood is in the process of being ââ¬Ëturnedââ¬â¢: ââ¬Å"This is the meaning of what Satan showed me in the vision! â⬠Rhoda shouts. Hardyââ¬â¢s use of the word ââ¬ËSatanââ¬â¢, emphasizes the hatred Rhoda has for Gertrude and perhaps jealousy, for ââ¬Ëstealingââ¬â¢ her husband ââ¬â although Gertrudeââ¬â¢s character is kind and gentle. In ââ¬ËThe Return of the Nativeââ¬â¢, the main dramatic incident is when Eustacia falls into the whirlpool and Clym Yeobright and Wildeve try to save her, but fail. Three bodies are pulled out, and only one, Clym, survives. Referring again to pathetic fallacy, the weather is awful when Eustacia falls into the ââ¬Ëboiling cauldronââ¬â¢. The slow realisation that Wildeve was actually holding on to Clym when Diggory Venn was seemingly just pulling Clym out creates images of horror. My favourite story is ââ¬ËThe Withered Armââ¬â¢, because I like Hardyââ¬â¢s use of magic in Rhodaââ¬â¢s vision, how Gertrudeââ¬â¢s arm became deformed because of this. Gertrude obviously has no idea how this happened. Hardyââ¬â¢s use of vivid description in the book is very effective throughout, but especially in Rhodaââ¬â¢s vision. Rhoda is obsessed with the idea of Farmer Lodge being with another woman, and sends her son to look at Gertrude and report back to her. When he says that Gertrude is shorter that Rhoda, she seems pleased and smug about herself. I like the way how Hardy has interlinked everything, e. g. Rhodaââ¬â¢s sonââ¬â¢s father is Farmer Lodge, the young man who was hanged was Rhodaââ¬â¢s son. I think it is a very clever story, and at the end, Gertrude dies at the fright of seeing Rhodaââ¬â¢s son dead, lying limp in the coffin. I think that the story shows that Rhoda is perhaps so obsessed about Farmer Lodge and Gertrude it is almost unhealthy, and because of this, maybe this is why she had the vision in the first place. I learn that Gertrude is forgiving, even though when she went to see Conjuror Trendle and he created the concoction of egg white and water, Rhodaââ¬â¢s image formed. Gertrude was surprised, but she doesnââ¬â¢t question it because she had no idea that Rhoda had anything to do with her arm.

White Collar Street Crime Essay - 1198 Words
White-Collar Crime or Street Crime: Which is More Costly to Society? What is crime? Merriam-Webster defines crime as ââ¬Å"an act or the commission of an act that is forbidden or the omission of a duty that is commanded by a public law and that makes the offender liable to punishment by that lawâ⬠(Merriam-Webster). There are many types of crime but the two this paper will focus on are street crime and white- collar crime. There is no definitive definition of street crime, but it is generally thought of as crime that occurs in public such as theft, robbery, car theft, arson, drug dealing, and vandalism.

He asserted that if not for crime the resources expended on these items could have been used for purposes more beneficial to society. The estimated cost for crime-induced production was $400 billion annually; 2) Opportunity Costs which account for the productivity loss of incarcerated potential workers cost society $5,700 a year per offender or approximately $130.3 billion annually. Since crime is a full-time occupation for many, the goods and services criminals could produce is a cost to society; 3) The Value of Risks to Life and Health includes the emotional and psychological impact of being victimized or the fear of being victimized, and the value of lost life and the value of injuries. These costs were estimated to be $574 million; 4) Transfers refers to the transfer of assets from victim to criminal. Robberies were estimated to have a $775 million cost. The gross burden of crime was estimated to be $1.7 billion or $4,118 per capita (Anderson, 1999).

To What Extent Does Genetic Inheritance Influence Behavior
ââ¬Å"To what extent does genetic inheritance influence behavior?â⬠A debate of nature vs. nurture, as in whether it is our inherited genes or environmental factors that affect our behavior, has been going on for years. There are no true experiments on genetic inheritance influencing behavior due to ethical reasons. Only quasi-experiments and theories of pre-existing data are available that are on genetics or environmental factors affecting behavior. With the few studies existing one can still argue that genetic inheritance is a major aspect in what affects behavior but environmental factors can be more affective. There are two main theories of human behavior. Some scientists and psychologists believe in the ââ¬Å"natureâ⬠theory, that oneâ⬠¦show more contentâ⬠¦We have grown to think in more abstract forms and sort our world by conceptualizing it because of the major growth in technology and science. Although, Flynnââ¬â¢s study is outdated and there are other factors his study does not recognize. For example, interracial mixing has increased largely as well in the past half century. Therefore the conclusion could be bidirectional but then again the technology boom could be the cause of allowing interracial mixing. Similarly to Flynn, Turkheimer searched for data on twins in a wide range of families. He investigated the role of environment and whether heritability of intelligence is equally high in all socio-economic classes. He found that the heritability of IQ for MZ and DZ twins was very high in affluent families. Among twins who grew up in the poorest families, the MZ and DZ twins had scores that varied all the same; therefore heritability of IQ is close to zero. The effect of growing up impoverished overrules genetic influences on IQ but in affluent families, IQ differences can be explained by genetics. However, Turkheimer compared old data from back to the 1970s and used IQ scores of 7 year olds. Taking 7 year oldsââ¬â¢ IQ scores and generalizing it for all ages is quite questionable. It is possible that it takes more than 7 years for environmental factors to make large impacts and that before then it is genetic inheritance impacting the most.

Carbon Nanotube Desktop Reactor with Plasma - myassignmenthelp
Question: Discuss about theCarbon Nanotube Desktop Reactor with Plasma. Answer: Introduction Carbon nanotubes show enormous panorama in uses through many industries such as the electronics and radical compounds. Growing isolated carbon nanotube is usually required most of these uses. Chemical vapour deposition procedures are now a routine in growing of carbon nanotubes. Chemical vapour deposition can support the growth of dense medium of elevated carbon nanotubes though cannot generate vertical carbon nanotubes. The latest study suggests that including plasma to carbon vapour deposition procedure can significantly enhance the possibility of developing vertical Carbon nanotubes.(Bishop, 2013) Benefits of adding plasma It helps in decomposing reactant gases used in the production of nanotubes. Generates an electric field that helps in the vertical alignment of the carbon nanotubes. Injects additional energy.(Chopra, 2012) Background research reveals four principal means of generating plasma for the plasma enhanced chemical vapour deposition systems: direct current, inductively coupled, RF triode and microwave. Plasma enhanced vapour deposition methods are mainly classified into three modules, and another associate module design: plasma coil, reaction chamber, electronics, controllers of operational condition, substrate holder and the heating assembly. Customer necessities and provisions are used in providing a guideline for the formulation of the initial concepts pertaining every module. (Huimin Liu, 2013) The ultimate design fits into 0.457m by 0.457m base platter and height within 0.305m. Reaction chamber comprises three orthogonal tubes mutually intersecting at the midpoint. A quartz tube is fixed at the end of one its tubes. A plasma wind is done on the tube to aide ignition of the reactant gases as they enter reaction chamber. Full substrate holder, adjustable electrode and the heating process get packed in one tray thats able to slide into or out of reaction chamber. The infrared sensor and the chamber are designed into a stand containing a linear bearing thats suitable for the purpose opening and closing of the chamber. (Jiyang Fan, 2014) The whole chamber comprises commercially available assembled components, with the electrode, system tray, heat sink, and system stand and substrate system.(Franssila, 2010) Design modules Essentially, a reaction chamber is the flundamental element of all plasma enhanced chemical vapour deposition systems hence much effort is accorded to it in terms of design. Its this chamber that houses the process of nanotube growth as well as plasma generation. It comprises of viewports, chamber walls, in and out reactant gas passage and an electrical feed. The rest of the modules depend on reaction chamber design. The internal chamber as a module hugely relies on reaction chambers interior geometry. Therefore, concepts needed to be employed for reaction chamber design first, before much effort was afforded the other modules.(Sharpe, 2009)A pumping system, infrared sensor and fittings are selected to enhance the process of making controllers of an operating condition. As for the supporting electronics and plasma coil, a matching network, power supply and coil design are developed. An electrode assembly is designed as an extra design work in the internal chamber assemblage. Strategies for plasma enhanced chemical vapour deposition Local plasma, plasma is created right over the substrate through growing environment. Remote plasma, plasma is generated separately from the growing environment after which its made to flow to the substrate. (Zhang, 2012)The main drawback of remote plasma is that weaker electric field necessary for nanotubes vertical alignment for vertical alignment of the nanotubes is easily overcome by any independent electric field separately generated near the substrate. Thus majority design concepts employ remote plasma.(Popov, 2008) Concept Summary Seven concepts as illustrated in the figures below were generated for this design with two of the catering for every type of the geometry chamber. All the concepts utilized both the local and plasma approaches. Materials used as stainless and quartz. Adjustable electrode stands out as a key design module here. The box section containing plasma system has antennae have the shape of a heating coil, located on the outer side of the chamber to aide ignition of the local plasma. The front section is open to facilitate substrate access. Remote plasma disjoins the electric field and power source. The section box containing inductive plasma helps create the remote plasma that moves in the chamber. One is required to open gas outlet end thereby providing for substrate access. The tube holding the remote plasma helps in adding that plasma to the chemical vapour deposition system with the oven as a heat source. Direct current substrate bias and remotely inducted plasma the above tube design employs the use of use of one quartz tube through which plasma is created using a coil at one end. The electrodes placed on opposite end allow for voltage supply. Pyrex cross design from commercial Pyrex cross has two ends, one for sample loading and the other one for plasma generation. A cross design (six-way) can also be generated in a number of ways. A steel chamber and spherical Pyrex with local plasma are also designed with the hemispherical Pyrex that allows us to view substrate through nanotube growth. Adjustable Electrode Sub module Comprises of the automatic adjustment which employs the use of a direct current motor the two wheels responsible for moving the electrode up and down. The seal has to be made dynamic enough to enhance electrode movement at a constant pressure difference within the chamber and atmosphere. There is also manual adjustment which uses a wound rod with the electrode attached to it. Rotation of the rod ensures that the electrode moves up and down.(Vossen, 2017) Discussions and Observations Laboratory research by most lab users who have tried different chemical vapour deposition setups helps us make a choice among the two leading concepts of design. The vast experience among laboratory users enables them to interact with most useful features that are essential in improving the system usability. Watching the lab users setup, grow the carbon nanotubes also enables us to understand the handling of the samples. Professional interaction with lab technicians doing plasma research helps greatly in making the decision on the remote and local plasma. Furthermore, they provide information involving the advantages of both sources of plasma as well as a valuable necessary consultation knowledge on a suitable method of generating plasma. Final Concept Remotely inductive plasma source allows easy decoupling of the plasma as well as controlling the electric field. Its also essential in improving system adjustability. Besides, it is relatively cheaper compared to microwave plasma and provides for a cleaner operation (Ostrikov, 2007) Therefore, exploring the option of six-arms cross provides for an enormous adjustment to be made in the coming times.(Vladimirov, 2005)Hence the choice of a cross design. With limited project time frame, buying the chamber parts the components helps in ensuring that the parts assembled are easily capable of holding the vacuum as well as save on time that could be used machining them.(Ramesh, 2009) Final Design The final designing program is put in three sectional assemblies as seen the figure below. They include; Reaction chamber- quartz tube that holds plasma and the body. Internal chamber- entails heating mechanisms, the electrode and the substrate holding. Base and supports entails chamber supports, internal tray support, IR sensor with its support and the overall base support for other bases. The whole setup is shown below; Chamber Design In making a design decision for the chamber, the cross geometry is purchased as its more flexible and has a huge range of standard components available to select from in choosing this. All of its projections attain Klein Flanges standards set by ISO thus allows profoundly easy fit all together. The gas is streamed through a fitting outlined in the diagram below. It then travels the quartz tube that is attached to two connect fittings to allow for easy exchange of fresh tubes as well as the tubes with different lengths. This tube is then wound with a copper wire, then linked to a plasma-producing generator. Another quick connection is then provided, to connect quartz tube with the other left end in the six-way cross-chamber. The upper and back The upper and back projection in this chamber has a number of cordial glass avenues that enable us to view the internal features as the lower projection helps us achieve an optical access to the IR sensor. The front projection allows for an elec trical feeding passage consisting of individual eight sealed pressure copper pins. Thereafter, the gas flows out through the standard KF projection that is attached to the steel hose connected to the vacuum pump. Internal Chamber Assembly This chamber performs the task of giving mutual support to every element used in carbon nanotube making process. The essential section of assembly encompasses a system tray, that is connected to electrical feed through projection by use of a set of screw collars and steel pins (dowel pins). These pins are then pressed to fit in the projection and slip to exactly fit into the system tray. The lower three pins holding electric feed into the system can be removed to help knock off any interference they may bring to the system tray. (Seshan, 2012) There are two rods in the grooves laid tray system, whose main role is supporting the gathering of the substrate and keeping it isolated electrically from the chamber and the system tray. Substrate assemblage comprises a heating element that is resistive (silicon) and the heat sinks (two). The heating element provides support to the substrate. The heat sinks hold the heating element, as well as allowing current through it, enabling it to heat up the substrate in the long run. The second figure below gives an outlook of how a heat sink is constructed(Mattox, 2016). To create the electric field, an electrode is used. It is supported by the quartz rods vertically set in the tray system. Silver tipped screw sets are then used to control the height. The electrode and the heat sinks are connected to one of the feed pins each separately. The remaining two pins will be used in the removable thermocouple for the purpose of IR sensor calibration. Lastly, the connection between the actual clamps, wires, is determined. (Popov, 2008) Base and Supports The base plate is made of alluminium and also holds the chamber supports, which are mounted to it. The supports help in keeping a fixed height of the chamber. It is also the base support into which the IR sensor is screwed. The stand for IR sensor gives a provision for adjusting the sensor vertically for the purpose of proper calibration to an appropriate height. The support for the system tray keeps the internal structures with system tray at the desired height designed. This holder, system tray, helps in proper adjustment of the stand aligning it with the chamber through an efficient vertical motion it provides. This holder is designed to be able to slide on the rail thus allowing movement of system tray completely from the chamber, as shown in the figure below. Essentially, its useful in substrate loading and off-loading, in the growing of the carbon nanotubes, enhancing cleaning of the whole system tray through its complete removal and replacement of the heating elements. Analysis regarding usability; INITIAL SET-UP Support the projection with the substrate frame on the slot of the chamber and then fix the gas to the tube inlet thereafter fix the pump to the chamber outlet. Slide the projection with substrate into the chamber and link every electrical feed from the projection supporting substrate to the electrodes. Put the substrate into a holder and then slide it gently and finish all the electrical links through the projections by linking the direct current power supply with the feed through. Link the coil with marching network, marching network and power source then the controller of the automatic network marching. Ensure all viewports and projections are in right positions.(Seshan, 2012) PROCESS SET-UP Induce a low pressure in the chamber by introducing inert gas like helium and open the gas flow while ensuring a desired rate of flow. Now put on the power source maintaining a desirable power level using an option of forwarding power in the generator, then wait until the generation of plasma in quartz tube is done, ensuring that the impedance source of 50 Ohms equals plasma impedance. After carbon nanotube reaches the desirable levels, put off the power source, vacuum and flow rates. Give it some minutes before embarking on dismounting of substrate stand and the flange in order to gain substrate access. Detach all the electrical connections carefully then take out the substrate. In case a direct current source is used instead, for power generation, then the electrode would have to be removed before getting an access to the substrate.(Popov, 2008) Validation Plan In ensuring that the project meets engineering specifications, a number of required experiments have to be conducted(Etching, 2008). All of the mandatory tests to be performed are provided in the figure below, in an order of low priority in their undertaking. To avoid help avoid failure in some parts, wall temperatures and pressure of the chamber are checked and controlled. A calibrated IR sensor is used in measuring temperature, whose analysis helps determine if the required conditions are achieved, and the pressure measured by a pressure gauge. Plasma creation is visually seen through its ignition in the clear quartz tube. A confirmation of the growth of carbon nanotubes is achieved through the viewing of certain black growth occurring on the wafer or scanning by electronic microscope. Finally, SEM will go on to prove that this system has the capacity to produce isolated nanotubes vertically.(Franssila, 2010) Risks and Countermeasures During the process of the undertaking of the project work, there is a certain foreseeable risk level that basically needs to be factored in the process of project work plan. It's therefore essential that we formulate the necessary measures to counteract these risks involved in the implementation process. Proper handling of such issues greatly helps in making the project within the stipulated timelines. The table below gives a summary of anticipated risks, problems as well as associated countermeasures (Vossen, 2017) Conclusion Evaluation of the above design concepts desires that a rating against the five critical criteria (adjustability, substrate access, fabrication ease, cost and size) be done to help come up with the best two options. System adjustability helps in increasing the rate of use of the system while at the same time reducing the ownership cost of the customer. Substrate accessibility enhances reduction in time between experiments as well as sample swapping between experiments. Easy fabrication enhances efficient assembling of the system thus meeting customer requirements profoundly. Cost as critical criteria helps keep in check project budget level reasonably well for the system. Desktop size then is critical to suit customer requirement. Every design is rated to ascertain its strength as well as a weakness with the best two options being a remote plasma box with six-way steel cross.(Ostrikov, 2007) References Bishop, C., 2013.
