The detection of defective members of large populations Essay Example

The detection of defective members of large populations Essay Example The detection of defective members of large populations Essay The detection of defective members of large populations Essay Recently your firm has made a series of costly errors in its group life insurance quotations. Your supervisor wishes to improve quality control. She has discovered a classic article in the field: Dorfman, Robert (1943), The detection of defective members of large populations, Annals of Mathematical Statistics, 14(3), pp. 436-440. Your supervisor has asked you to read this article, and then write a review of the article. She has specified that the review should be no longer than 1200 words. Before the outbreak of World War Two, in 1943 Harvard economist and mathematical statistician Robert Dorfman wrote an article that is integral and significant in statistics. His article The Detection of Defective Members of Large Populations (TDDMLP), reveals Dorfmans intricate thinking and now part of the Annals of Mathematical Statistics that is published by the Institute of Mathematical Statistics. Moreover, in the article he emphasizes on the process achieving an efficient method for eliminating all defective members of certain types of large populations. This idea follows close to the importance of quality control, which is vital in all types of financial institutions, from banks to insurance companies. In conjunction, Dorfman uses the analogy of discussing blood samples as one application of the quality control methodology. Ultimately, TDDMLP can be utilised in proving indirectly that undergoing shortcuts do not completely reduce quality, if and only if the analytical theory is supported by it. With Dorfmans main objective to identify defective individual members of a large populace in a less expensive and tedious process, informs the reader that testing of combined samples can be beneficial in an economical way. By experimenting on a large-scale population such as the United States Public Health Service and Selective Service, Dorfman collects the blood samples from the men inductees from the armed forces, and conducts experiment with them to detect which men had a syphilitic antigen. In TDDMLP Dorfman proposes that under a statistical and probabilistically approach of the elimination of defective people can be minimised by increasing the efficiency of detection. Hence with his intention to pool the samples into groups will reveal the extent of saving compared to individual testing. In this experiment, Dorfman undergoes a methodological and practical process to demonstrate his idea. He executes this by first pooling N blood samples into group pools with n members, rather than testing each blood sample from the individual men. With the assumption that the tests are conducted under sufficiently sensitive and specific rules, if the group pools contain no syphilitic antigen, then the pool will test negative, which this indicates none of the people in that batch are infected with syphilis. On the other hand, if a syphilitic antigen is found in the pool, then at least one of the members in that pool is affected, so then each member in that pool will be retested separately to determine which of them is infected. In addition this process will determine the most efficient size of the pool groups with the assumption that since the population is large enough the discrete binomial distribution can be applied. Furthermore his findings also reveal the amount of savings attainable by conducting the experiment with group pooling. In the article, Dorfman shows three important findings, which are that as the prevalence rate increase, the relative testing cost from individual testing increases and both the number of people in each pool (n) and the amount of savings decrease. One of the key deductions found from the experiment is that the extent of savings attainable will increase as the prevalence rate decrease. This can be numerically examined with reference to Table 1 in the article, as it shows the relative testing costs for selected prevalence rates to individual testing. The table shows that as the prevalence rate increases amongst the members, the savings that could be made from pooling diminishes; this is because when there is a low level of prevalence rate of defectives, it is likely that a new pool formed from the untested samples will prove to be negative. So if blood samples results in being negative, then the test for that pool is finished, otherwise the test should run individually again until a defective is detected. By following this procedure until a negative pool is found, the amount of savings attainable would increase by average 5. 5% with each extra percent decrease in the prevalence rate. Also Dorfman findings reveals that the amount of savings attainable can be maximally done at 80% with prevalence rate of 1%, and with a much higher prevalence rate of 30%, there is only 1% of savings, hence the extent of savings attainable will increase as the prevalence rate decrease. In addition, as Dorfman uses group testing instead of individual testing shows that the relative testing cost increases as the prevalence rate increases. In conjunction, the amount of economical benefit that can be gathered depends on the group pool size and the prevalence rate. Dorfman shows the optimal size of the pool groups (i. e. amount of n) for different levels of prevalence rates diagrammatically and numerically. From Figure 1 in the article, it displays the shape of the relative cost for prevalence rates ranging from 1% to 15%. By looking at the minimum points of the curves, the optimum group size for a population with a known prevalence rate is the integral value of n, this has the lowest corresponding value on the relative cost curve for that prevalence rate. Dorfman revealed that the maximum amount of people per group at the lowest prevalence rate of 1% are 11 people, and with the highest prevalence rate of 30% with 3 people per group. Evidently this proves that it is more economical to detect defectives by group pooling than to test individually. Although TDDMLP revealed great insight into the efficient method for eliminating all defective members of certain types of large populations, by finding it more economical and time wise to group pool rather than testing individually, however Dorfman fails to take into account any technical failure or operators error. With the possible degree of impurity or imperfection and taking the shortcut of combines testing may result to incorrect findings. Yet Dorfman used a process that was in a logical and coherent order, subsequently there would be a low level of possibility of faults. This can be related to quality control of firms, in which improving quality control for firms is becoming an opportunity cost for raising revenue. Robert Dorfmans remarkable and notable article The Detection of Defective Members of Large Populations, is renowned for its statistical findings on economical benefits in group pooling compared to individual testing in detecting defectives amongst a large population. Dorfman uses the connection between prevalence rates of syphilis to the pool size and the extent of savings attainable. His results show that as the prevalence rate increase, the relative testing cost from individual testing increases and the number of people in each pool (n) and the amount of savings decrease. Hence the relative cost and the amount of savings achievable have an indirect relationship. This shows that quality control can at times be hindsight, when costs want to be reduced. Bibliography 1.

Argument Synthesis Essay Example | Topics and Well Written Essays - 750 words

Argument Synthesis - Essay Example First, the commercialized culture of the United States is beyond reasonable doubt that it has created a vast network of trade. For instance, the focus on the Christmas season is such an influential commercialism that has a tremendous impact on corporate growth. During the Christmas, the public display is extensively covered all forms of commercial advertising. The emergence of commercialize culture is a substantial aspect of the North America consumerism attributed to the response of the corporate stakeholders ideally to achieve a fair consumer environment. The anti-tax welfare movement had an intrinsic impact in assisting the local government as well as states education institutions to enter the commercial adverting arena. In addition, the lifestyle of material attainment hastened the corporate growth in regard to institutions seeking sponsors both governmental and private organizations in the pursuit of material acquisition. For instance, churches benefited sponsorship by Federal E xpress to acquire materials such as transport facilities among others (Katherine Anne Ackley 344). Quintessentially, the strategic target of kid in childhood institutions encountered a relatively poor attention by the commercialization phenomena. This position taken into concern in this case was the idea that child are innocent hence need to shield them from the sacrilegious advertising. However, the trend has reversed as modern TV advertising in the United States subjects average children to approximately 40,000 advertisements. The commercialized culture is dynamic from generation to generation to accommodate change. In this perspective, the modern generation of the millennial is outspoken. Therefore, the need for recognition of several brands targeting the group is the modern way to reach the consumer in every experience they indulge in to buy or browse sales. As a result, the fashion market is subject to change due to generations influence. Anna Quindlen claims that life does not necessarily have to entail material wealth to be fulfilling. However, the day-to-day struggles of life are made for the sole reason of attaining material wealth. Although it seems contrary, life is about meeting our needs. Some are basic needs while others are luxuries. Overall, the main goal of life is to meet our daily needs irrespective of whether they are basic or luxurious (tulsatownhall.com). Additionally, the exchange of goods and service is what leads to economic growth that promotes the general well being of the human race. At the individual level, each person defines what he or she consider as mandatory to have, as well as what to reserve as luxurious. However, this is not limited to a certain definition since it is dependent on an individual (Katherine Anne Ackley 374). Regarding the American popular culture, the choice of what a consumer perceives worth prioritizing is influenced by the consumer behavior that dictates wealth of good is beyond plain shopping. Culture div ersity is among the robust factors that drive North American consumerism. Life presents a variety of choices hence the American people face a difficult time making choices. The online transaction is an excellent example of how consumers mange to avoid socializing especially with the reliable choice of eBay (.www.cengage.com) In the synthesis of North America consumerism, the labor industry is significantly influential on the economy. To be precise, they are prevalence in job recruit that favors single childless, young men and women to young

History in Distributed Databases Essay Example | Topics and Well Written Essays - 2500 words

History in Distributed Databases - Essay Example In this scenario, a distributed database design allows the organizations to divide a database over different hardware devices, but with a central management control. The basic purpose of implementing distributed databases is to offer higher reliability and superior performance. Without a doubt, the division of a database into multiple locations can provide a number of advantages to organizations (Holmes; Hoffer, Prescott and McFadden). Additionally, this way of data storage offers superior control over particular data. In this scenario, the load of the database management is divided among several hardware devices and burden of processing is shifted from a single location to multiple locations. Normally, a distributed database is developed on the basis of business departments, or geographical areas or companies. In view of the fact that the database appears at local location to each business department inside an organization hence it offers quicker response times for the database user s. In addition, these departments are also smaller as compared to the size of the overall organization, as a result the processing load over the server also reduces. The research has shown that the majority of organizations prefers to develop distinct business sectors for particular tasks. For instance, organizations can develop different organizational units for human resources, accounting, and sales departments. Moreover, they develop a distributed database to assist in running the operations of particular business units all the way through the company, at the same time as establishing and maintaining authority from a central server. This technique is also useful in separating the data and hardware all the way through the organization, as a result the performance and control over the database also improves (Holmes; Hoffer, Prescott and McFadden). Though, the distributed databases require the development of database using all the traditional techniques of database development excep t they are based on a different perspective. They are being developed to get the advantages of central access by company head office, at the same time as supporting local access for particular company sectors. In this scenario, this database design technique is very useful for organizations that are distributed all over the world. Additionally, these databases are also used by the companies that support multiple portfolios. For instance, a number of industries such as hospitality, manufacturing and banking can take benefits from the implementation of distributed databases. In addition, a distributed database can also be useful in supporting an organization in their accounting unit. Moreover, an international organization that has several offices in various countries of the world can normally develop a distributed database to support its business operations in each country. In this scenario, this division of geographical areas would allow the local country to get access to data and p erform operations faster. Also, the organization would be able to use the central database to get access to data available in each country without having an impact on local application. Without a doubt, distributed databases offer superior reliability and flexibility for the organizations. In view of the fact that the data is located on different servers, hence it can straightforwardly be copied onto new hardware devices and database structures all the way thro

Effects of Improving Productivity in Lost Foam Industry Essay Example for Free

Effects of Improving Productivity in Lost Foam Industry Essay The lost foam or expendable pattern-casting process is a relatively new process in commercial terms, but is gaining increased attention due to the environmental and technical benefits that are achievable for some types of casts. In the lost foam casting process, an expendable pattern is formed out of polystyrene foam. Patterns can be made manually, using automated systems or by molding those using a permanent die. Manual pattern making typically involves carving blocks and gluing sections together to build up the desired shape. The finished pattern is a single piece (i. e. no cores) incorporating all necessary gating systems. Process details and organizational: Lost foam casting is a type of investment casting process which uses foam patterns as the investment. This technique takes advantage of the properties of foam to plainly and inexpensively form castings that would be complicated or impossible, using normal cope and drag techniques. Why foam casting? In the world of metal casting, there are only three non-captive aluminum lost foam job shops exist, where the traditional process called sand casting remains at the top. But most of the companies could offer only with a lost foam facility. The manufacturers gives value-added castings, though the casting part might be initially more expensive, but the entire cost of the component, for the reason that of reduced or eliminated machining, less assembly and less of the other aspects, can make it more commercial for its customers. The green sand, permanent mold and die cast are lot of established processes but there is only handful of lost foam aluminum users. Even though the fact that there are only a small number of lost foam job shops across the country, some of the Irish and American Foam Cast still have to compete in the entire metal casting market. Due to the higher tooling costs than traditional casting the customers disregard lost foam strictly. Initially customers might be turned away by costs, but comparing to those cast by traditional methods certain lost foam components can be less-expensive. When estimating lost foam, with a total-cost point of view from design to finished component, customers save on unavoidable expenses in sand casting. Some of the customers were hesitant on utilizing lost foam because of its intricacies, when the Foam Cast drew in its first potential customers. But lost foam supplies the ability to design without interior while casting in geometry and features from the start. The lost foam can facilitate the staff to execute direct administration correctly over the casting process even with in the facility. Lost foam can also fabricate multiple parts to make one casting from thin to thick wall components independent of a riser. Advantages of Lost Foam Casting †¢ The lost foam casting can be used for precision castings of ferrous and non-ferrous metals independent of size. †¢ Compared to sand casting fewer steps are involved in lost foam casting †¢ In the foam casting system ‘Core making’ is eliminated. †¢ Binders or other additives and related mixing processes are eliminated. †¢ High dimensional accuracy can be achieved and thin sections can be cast (i. e. 3 mm). †¢ There is lower capital investment. †¢ The flasks used are less expensive and easier to use because they are in one piece. †¢ The need for skilled labor is reduced. †¢ Multiple castings can be combined in one mould to increase pouring efficiency. †¢ Lower operating costs can be achieved for appropriate castings. †¢ Complex castings, particularly internal sections, which require high dimensional accuracy and have thin sections, can be produced very cost effectively in comparison with to conventional sand molding processes. †¢ Fettling and machining is minimized due to high dimensional accuracy and the absence of parting lines or core fins. †¢ The shakeout process is simplified and does not require the heavy machinery required for bonded sand systems. †¢ High levels of sand reuse are possible. As little as 1-2% of the sand is lost as a result of spills. Periodically a portion of sand may need to be removed or reclaimed to avoid the build-up of styrene. Advantageous Productivity Areas of Lost Foam Process in Industry: ? Reduce Production Costs – The lost Foam process provides opportunity to reduce the labor as well as the content of energy and make other efficiency improvements must be pursued. As the activity based cost accounting approaches do the Lean manufacturing, six sigma and other concepts to progress operating efficiencies need to be practiced. Revolutionary technologies and process changes also should be investigated to achieve metal casting without the use of tooling. The industry should investigate the application and blending of statistical, shop floor layout, computer numerical control, and scheduling technologies to radically change the nature of EOQ’s, production release sizes, inventory levels, and delivery performance in metal casting plants. ? Reduce the Energy Content of Cast Products – In the lost foam system the energy consumption can be reduced by improving product quality thereby decreasing the scrap and melting requirements. The Improvements in equipment and process efficiencies can also save energy. The foam casting industry should build up a complete understanding of thermo physical behavior of alloys in melting, flow, and solidification as well as the capability to accurately simulate these behaviors. ? Waste Management – In the foam casting system, in order to enable increased reuse of foundry sand and other by-products and waste streams, more environmentally sound binders, and better emission treatment, the improvement in process are required. These Process improvements will also help to reduce scrap and thereby waste in casting processes. ? Reduced Labor Content of Cast Products –the current foam casting practices must be investigated in order to identify opportunities to decrease the number of steps in the process, develop and implement no-touch casting processes, and execute advanced information and control technologies. ? High-Quality, High-Performance Engineered Cast Components –the techniques to progress quality, precision and performance will result in fewer customer returns. The foam industry must develop an understanding of all process variation which affects the performance of castings in their applications; and develop process controls to ensure that variation is within allowable limits. Better performing products will also open new markets for metal castings. Tools are needed to capture digital, analog, or computer vision signals from all levels of the metal casting process to provide real time feedback about process status and to provide the ability to correct variances before they become product defects. The current status of Metal Casting Industry: According to Donahue â€Å"There have been significant advances from the past two years in aluminum lost foam, and yet domestic growth is almost non-existent†. The development have been made possible not because of a large group of lost foam metal casters but because of individual metal casters. According to Donahue, this influx of capital has contributed to advances in eight key areas of aluminum lost foam casting: * New types of foam which resists the folding and creating voids; * Improvement of the metal interface with sand by coatings; * Sand with low expansion rates that fill more quickly and completely; * More capable compaction systems; * reduced porosity through pressurized solidification; * Alloys that is more compatible with the filling process unique to lost foam; * modeling software; * gating advancements, such as hollow fiber sprues. Lean Manufacturing Lean Manufacturing is an operational strategy oriented achieving towards the shortest achievable cycle time by eliminating the waste. Its key thrust is to increase the value-added work by eliminating waste and reducing incidental work. The procedure often decreases the time between a customer order and shipment, and it is designed to radically improve profitability, customer satisfaction, throughput time, and employee morale. The advantages are lower costs, higher quality, and shorter lead times. The term lean manufacturing is invented to represent half the human effort in the organization, half the manufacturing space, half the investment in tools, and half the engineering hours to develop a new product in half the time. Jones and Mitchell (2006) as cited in Clive Atkinson Dr Margaret Linehan suggests Four significant benefits that can be gained through the adoption of lean management to an organization. First, increased productivity with the same workers with the existing resource levels. Second, the Improvement of delivery of work within less time. Third, reduction of error or defects and improved quality. As a Fourth one, Improved Customer satisfaction derived from the improved staff morale and a stable workforce. The characteristics of lean processes are: 1. Single-piece production 2. Repetitive order characteristics 3. Just-In-Time materials/pull scheduling 4. Short cycle times 5. Quick changeover 6. Continuous flow work cells 7. Collocated machines, equipment, tools and people 8. Compressed space 9. Multi-skilled employees 10. Flexible workforce 11. Empowered employees 12. High first-pass yields with major reductions in defects Lean Manufacturing integrates the use of Heijunka, level sequential flow, the heartbeat or pace of the production system, continuous flow manufacturing, cellular manufacturing, and pull production scheduling techniques such as Kanban. The Lean module explores the 5 Principles: †¢ Value: it deals with –What the customer is willing to pay for. †¢ Value Stream: Actions which adds value to a product or process. †¢ Flow: The continuous movement of product, favoring single-piece flow and work cells versus production lines. †¢ Pull: Replacing only material that is used and eliminating excessive inventory. †¢ Strive for Perfection: A relentless elimination of waste on a never-ending basis. Applying Kaizen as a Tool of Lean Manufacturing Technique: Kaizen Event: This is a quick-hit method for Lean process improvement. This tool needs organizational learning and readiness for implementation and is a power tool to eliminate waste in the facilities of casting industry. . Tools: Kaizen Model Kaizen was created in Japan following World War II. The word Kaizen means continuous improvement. It comes from the Japanese words kai which means change or to correct and Zen which means good. The Mixed model, one piece flow manufacturing can become a reality only when setup can happen in seconds. In these days several companies are doing mixed model assembly. Progressive automobile manufacturers use mixed model assembly methods to customize each vehicle as it comes down the line. The power of the approach presented in kaizen for quick change over is to help make it possible to do mixed modeling in production as well by making changeovers even faster. Kaizen is a system which involves every employee from superior management to the cleaning crew. Everyone is encouraged to come up with small improvement suggestions on a regular basis. This is not a once a month or once a year activity, it is a continuous process. These repeated small developments add up to major benefits. These will result in improved productivity, improved quality, better safety, faster delivery, lower costs, and better customer satisfaction. Above all of these benefits to the company, the employees working in Kaizen-based companies generally feels easier to work and more enjoyable resulting in higher employee moral and work satisfaction, and lower turn-over. With every employee looking for ways to make improvements, the expected results will be: Reduces Waste: In particular areas such as inventory management, waiting times, transportation, and worker motion, employee skills, over production, excess quality and in processes kaizen model will reduces wastage. Improvement: it improves in space utilization, product quality, use of capital, communications, production capacity and in the maintenance of employee. Kaizen Offer: It provides immediate results in the organization. Instead of focusing on large, capital intensive improvements, Kaizen focuses on creative investments which solve continually more number of small problems. Still the large and capital projects and major changes in that are needed; nevertheless kaizen improves the process of capital projects, the real power of kaizen is in the ongoing process of frequently making small improvements which develops the processes and reducing waste simultaneously. SMED SYSTEM: The other tool called SMED system is a process which makes possible to perform arrangement of equipment and changeover operations with in ten minutes, and is also used as an element of Total Productive Maintenance –TPM. Effects of 1. Forming of Implementation Team: The production employees/executors and professional team members, having responsibilities in their own sectors, represent the best alternative for team members. The purpose in implementing the 5S techniques is to enlarge the effectiveness through the development of knowledge and skills of the workers, and their responsibility. By this technique workers become more dedicated to their work; they are capable to understand appropriately the given situation and can take the correct decisions. Hence the implementation team members must act as a machine, production, tool and design technologist. 2. Training: The maintenance employees have to perform changeover team and machine setup has to be introduced into and qualified in implementing new methods and the procedures introduced into changeover procedures minimum once a week. Clarifying all the misunderstandings, training is forecasted to be done per team and questions as well as giving clear directions to enable faster and easier tool exchange (SMED). 3. Survey and screening of the situation prior to the method implementation Every changeover detail are recorded in video and complete work activity sequence is written down. Every move and every activity of the operator have to be recorded specifically, hence any unnecessary activity to attain even worse results. The same procedure recording should be done after implementing the method to establish the effectiveness in both applying the method and accomplishing the result (SMED). 4. Classification of Activity: In the classification of activity it is consists of the analysis of recorded material and the activities which can be divided into two groups: the internal and external ones. External activities are all the set up activities which can be performed while machine is in operation; where as the Internal set up activities are the ones that can be performed only if the machine is not in operation. The Internal activities refer to the dismantling of used tool, to the mounting of new ones and ascertaining communication in line of machine tool (SMED). 5. Transforming internal activities into external activities: The Transformation of internal activities into external activities is much possible. It is the most proficient procedure ever for decreasing machine outage rates (SMED). 6. Improvement of internal activities minimization – Set the tools visually, at the hand of operator (5S) – Using the connectors that may be rapidly exchanged for all tool power sources (5S) – Possible Usage of as many locating pins for accurate tool positioning. (SMED) – Cranes with sliding transporters (SMED) – Using of cranes for heavy tools only (SMED) – Using of standard tools as possible (SMED) 7. Improvement of External activities: – Placing visual markings for easier and faster identification (5S) – Using check list to prevent unpredictable events in resources preparation (5S) – â€Å"At hand† tool organization (5S) – Work place organization that decreases tool search time (5S) – Using appropriate tool preheating machine along with adequate device (SMED). 8. Forming and Standardization of the SMED procedures. 9. Saves quantification of savings reached by SMED. 10. CIP (Continuous Improvement Process) Applicability of Lean to Lost foam Industry: The five-step thought process for directing the implementation of lean techniques is easy to remember, but not easy to achieve: 1. By using the product family –the specification of value from the standpoint of the end customer. 2. Elimination of steps when necessary, that do not create value and identifying all the steps in the value stream for each product family. 3. Make the value-creating steps occur in tight sequence such that the product will flow smoothly toward the customer. 4. As flow is introduced, permit customers to pull value from the next upstream activity. 5. As value is specified, value streams are identified, wasted steps are removed, and flow and pull are introduced, begin the process again and continue it until a state of perfection is reached in which perfect value is created without any waste. There are several approaches an organization must take to meet the desired goal. Here, are some outlined tips to ensure a continuous lean transformation. 1. Identifying the company’s cultural model: Culture answers the question of how do we do things around here? and is actually the accumulation of leadership behaviors. Any organization which is serious about becoming lean needs to identify its cultural model and determine how to close the gap from the current cultural state to the ideal future cultural state. Once the base of improvement action works to build new principles, values and behaviors into the organization, then the ideal culture aspired to and begin to work on organized progress toward that ideal state is to defined. In the end, the organizations culture determines the ultimate success of any lean transformation. 2. A process improvement culture should be build: After identifying this model, a culture that practices process improvement should be build as part of daily life. Changing from a reactive culture to a process-improvement culture requires embracing an opposite approach. 3. Establishing a practice of leadership involvement The senior leadership committed to lean improvement only to drop off after the implementation gets started. Bringing leaders to the point where they recognize how to seek out waste before removing it drives the success of lean transformation. 4. Continually engage in rapid improvement events The most effective way a manager or manufacturing engineer learns how to apply lean tools and concepts is through participation in the initial week-long improvement event. The next step is to establish a series of these events as you develop new processes and uncover additional areas of waste, which will help you incorporate lean into every aspect of the business. Effects of Improving Productivity in Lost Foam Industry: Metal Casting industries that apply Lean manufacturing principles can be seen improvements in the following areas: †¢ Reduced Manufacturing Lead Time to less than 1 day †¢ Improved Delivered Quality – The defect rate is reducing to Six SIGMA level which is 3 Parts Per Million †¢ Improved Delivery Performance to 99+% †¢ Increased Inventory Turns to greater than 50 turns per year †¢ Reduced conversion costs on materials to finished goods is to 25 – 40% which is less than mass producers †¢ Reduced Manufacturing space to 35 – 50% which is less than mass producers †¢ Reduces New product development rate to less than 6 months References: Clive Atkinson Dr Margaret Linehan, An Analysis of Lean Management Procedures within Irish Motor Dealerships: International Journal of Buisnessand Management Vol . 3, No. 11, Retrieved July 18, 2009, from http://ccsenet.org/journal/index. php/ijbm/article/viewFile/894/849 Dennis Sowards, Lean Thinking is not a Fad Diet, Retrieved July 18, 2009, from http://www. masetllc. com/news/pdfs/0306-1. pdf Lean management practices in the pharmaceutical industry Heiko Gebauer, Michael Kickuth, Thomas Friedli International Journal of Services and Operations Management 2009 Vol. 5, No. 4 pp. 463 – 481 Kaizen, Retrieved July 18, 2009, from http://www. graphicproducts. com/tutorials/kaizen/kaizen-benefits. php Lost-foam casting, Retrieved July 18, 2009, from http://www.reference. com/browse/wiki/Lost-foam_casting Modern casting, Retrieved July 18, 2009, from http://goliath. ecnext. com/coms2/gi_0199-3666396/Finding-a-niche-with-lost. html Lost Foam Foundries find Energy-Saving Opportunities, Retrieved July 18, 2009, from http://www. foundrymag. com/feature/feature/67804/lost_foam_foundries_find_energysaving_opportunities Hobert E.

Writings †¢ (With Richard Durham) The Greatest: My Own Story, Random House, 1975. Biographical Information Three-time world heavyweight boxing champion Muhammad Ali, known for his lyrical charm and boasts as much as for his powerful fists, has moved far beyond the boxing ring in both influence and purpose. Ali won an Olympic gold medal and later tossed it into a river because he was disgusted by racism in America. As a young man he was recruited by Malcolm X to join the Nation of Islam. He refused to serve in Vietnam--a professional fighter willing to serve time in jail for his pacifist ideals. He has contributed to countless, diverse charities and causes. And his later years have found him interested in world politics as he has battled to keep Parkinson's disease at bay. Muhammad Ali was born Cassius Marcellus Clay, Jr., on January 17, 1942, and was raised in a clapboard house at 3302 Grand Avenue in middle-class Louisville, Kentucky. He began boxing at the age of 12. A white Louisville patrolman named Joe Martin, who had an early television show called "Tomorrow's Champions," started Ali working out in Louisville's Columbia Gym, but it was a black trainer named Fred Stoner who taught Ali the science of boxing. Stoner taught him to move with the grace of a dancer, and impressed upon him the subtle skills necessary to move beyond good and into the realm of great.
