...Expert system for the definition of the cutting parameters and machining strategies 1 L.Zaquini1, J.Charpy1, J-P. Bendit2, T.Voumard3, P-E Mathez3, L. Béguelin3 HE-ARC-Ingénierie LMO (Laboratoire de Machines-Outils), University of Applied Science, Le Locle, Switzerland, 2 Jurasoft SA, Porrentruy, Switzerland, 3 Haute Ecole ARC – Software Engineering, University of Applied Science, St-Imier, Switzerland, Switzerland, Abstract The definition of the cutting parameters (Vc, fz, ae, ap), and the definition of the machining strategies or the strategies to engage the tool in the material and to start the cutting process, are usually requested by the CAM systems as input information. These data are usually strongly influenced by the consolidated experience of the operators, by the specific previous similar machining cases and by several other factors depending on the machining practices. In a project, financed by the Swiss national organization for the industrial research, the authors have developed an expert system (ES) in order to get this information through software processes. The paper shows the structure of this expert system. The ES has been realized through the definition of ontology of components and elements of the machining. The ES includes a very large data base of cutting parameters, and is based on the establishment of rules for the competition between the machining strategies. The ES includes learning methods which are able to identify similar operations. The learning...

...Final Paper Wrestling is one of the oldest sports in the world. No one is sure who invented the sport but it was first implemented as a real sport in the first Olympics in the year 776 B.C. The origins of wrestling can be traced back 15,000 years through cave drawings in France; Babylonian and Egyptian relief's show wrestlers using most of the holds known to the present-day sport. More modern day wrestling has weight classes implemented so participants will wrestle people that weigh the same as them, thus starting a trend known in the wrestling world as cutting weight. Weight classes in wrestling were implemented in order to insure the optimal amount of fairness for each wrestler before they step out onto the mat. I believe that weight classes are positive to the sport but also negative. Positive in the fact that you don’t have a kid who weighs 103 wrestling someone who is 185, that just wouldn’t make sense. It makes it so everyone that goes out there are roughly the same weight so size doesn’t play a roll. But, this causes many issues as well. I know from experience the side effects of cutting weight. You feel weak, tired, and hungry; you get cotton mouth, and extremely aggravated over little things, everything pisses you off, it’s just an awful mood to be in. Cutting weight often is misconstrued and everyone believes that you just starve yourself to make weight. In some occasions this is true, but that is the wrong way to do it. There is a right way to cut weight and a...

However machining this composites find difficult because of the reinforcement particles. Tools wear more quickly and reduce the life of the tool. This paper presents the experimental investigation on machining two different A356 matrix metal reinforced with 10 % and 20 % by weight of Silicon carbide (SiCp) particles is fabricated in house by stir casting method. Fabricated samples are turned on medium duty lathe with Poly crystalline Diamond (PCD) insert of 1600 grade at various cutting conditions. Parameters such as power consumed by main spindle, machined surface roughness and tool wear are studied and influence of SiC particles percentage on tool wear also discussed. Scanning Electron Microscope (SEM) images support the result. It is evident that, tool wear is strongly dependent on reinforcement percentage.

...Name: Tutor: Course: Institution: Date: How to Lose Weight without Losing your Mind Introduction Over the years, people have spent a lot of time debating, discussing and sometimes battling over the pros and cons of virtually all diets products and programs available in our society. One of the critical issues has been to understand a diet with short term weight loss results without any serious health consequences. Research shows that virtually in a fort night, there is a new diet that comes up. Yet with all these debates people are not loosing weight. Not only are friends, relatives, and individuals driving themselves crazy, but they are exposing themselves into mind and body damages by consumption of these diets and pills. This paper gives the process and an analysis of how one can lose weight without losing their mind. Discover your Calorie Target The first step is to know the amount of calorie that one should be eating everyday in order to loose, gain, or maintain your weight. Research show that in order to loose one pound of fat then one have to deduct 3,5000 calories in the body. It is also true when one wishes to gain weight where an addition of 3500 calories gains one pound of fat. There are available online resources which can help one to know the amount of calories one should be eating everyday. Example is freedieting.com. After one has identified the amount of calories oe should consume, it is important then to commit. This where people lose their mind as...

...Also, “According to the US Consumer Product Safety Commission, during the 2011-12 school year more than 13,700 kids, aged 5 to 18, were treated for backpack-related injuries.”, proving textbooks are dangerous (ProCon.org). This is a scenario in which a student attending a school with no tablets might experience. The student has just gotten off the bus, and is walking back home toward his or her house. The backpack that the student is carrying has textbooks from math, English, social studies, science, and grammar inside of it. The student walks with a hunched back because of the weight, and when the student gets home, he or she sets the backpack down heavily, just inside the door. The student then goes on to stretch his or her back, and emits a groan. This is only the beginning of a long and tiring school year, and the continued strain on the student’s back causes that student to get chronic back pain, and always walk hunched over. All of this could easily be avoided if the student had a tablet, which only weighs 1-2 pounds, instead of several textbooks. Textbooks have caused many injuries to students, and...

...Electronic Paper For a thin and bendable display, Fabric PCs will rely on a cutting-edge technology called e-paper, or electronic paper. The technology behind e-paper was pioneered in the 1970s by Nick Sheridan at the Xerox Palo Alto Research Center and has continued to evolve since that time. Today there are several different implementations of the basic e-paper concept. One example of e-paper technology is called E ink, made by the E ink Corporation. We'll very briefly touch here on how E Ink technology works, but to learn much more about it, read How Electronic Ink Works. Basically, this form of e-paper is created by sandwiching millions of tiny plastic wells between two sheets of flexible plastic. Each well contains both white and black particles, suspended within a clear fluid. The key to this technology is that the white and black particles have opposite charges, so when an electric voltage is applied to individual wells -- through circuitry embedded underneath -- the black and white particles can be separated to opposite sides. In this way, the face-up side of each well can be set to appear either as black or white as seen through the top layer of clear plastic. Each well functions as a separate pixel on the E ink display. E-paper, based on this type of design, can be curled or even folded like a sheet of laminated paper, and because of its light weight and flexibility it's also much less fragile than traditional displays. Fujitsu's Fabric PC concept designs take...

REZAIEy, B. OSTADI*z and S. A. TORABIy yDepartment of Industrial Engineeing, Faculty of Engineering, University of Tehran, PO Box 11365/4563, Tehran, Iran zDepartment of Industrial Engineering, Faculty of Engineering, Tarbiat Modares University, Tehran, Iran (Revision received August 2006) The objective of this paper is to apply the activity-based costing (ABC) approach together with traditional costing (TC) for parts costing in flexible manufacturing systems (FMS) with the A(2) level of automation. We propose a new model for the implementation of ABC using the product cost tree concept. First, the required resources and activities for each part are recorded, and then their costs are calculated using the appropriate cost formulae. This model was applied in a forging industry. A comparison and analysis between ABC and TC was then carried out based on the computational results obtained from the case study. The results indicate that the ABC outputs are more reliable than the TC outputs, and thus the ABC approach is a more acceptable tool for parts costing in FMS.

...Why do Americans love fast food so much? Is it the greasy smell and taste that excite their senses, is it the connivence of fast food restaurants or is it the price of fast food that draws American into eating a lot of fast food. Approximately 11% (27 million) adults in the United States of America were diagnosed with some form of heart disease in 2016. Unfortunately, obesity and obesity related disease and illness have become a major concern. Many Americans turn to exercise, food diets, diet pills and even weight loss surgery to loose weight or to combat the increase and risk of obesity-related diseases. For years many question whether a vegetarian diet is preferable than a vegan diet. The research presented in this paper will differentiate...

... She heard there was a diet that would allow her to maybe stop taking insulin all together or at least only have to take pills. Being an avid reader and researcher she found the doctor’s book where she learned cutting carbs and sugar from her diet could reduce her dependence on insulin. Being a typical self-absorbed teenager I don’t remember many of the details of her weight loss or what if any medical issues occurred. I do however remember the crazy looks and discussions that occurred when my mom sent me out for fast food and I would ask for a burger without a bun. There are a lot of mouth breathers in the fast food industry, and asking some of these people for this simple request was just too much for them to comprehend. My mom lost over 100 pounds in less than a year, when combined the diet with water aerobics. Because there was way less sugary and carb rich foods in the house I lost a lot of weight also. Looking back at pictures of that time both my mom and I never looked better. About 10 years ago I fell in love with a girl who barely knew I existed and decided that I would win her heart by losing weight (unlike the previous admission, I can’t use being a teenager as an excuse.) I started the diet without reading anything or doing any kind of research besides a 5 minute conversation with my mom on how the diet works. This was in 2003 I believe and it...

...Abstract This article presents the role of communication research in the clothing industry in Bangladesh. The aim of our research was to show how these clothing and textile companies use a marketing communication mix for the promotion of products and brands. Our findings suggest that a properly used marketing communication mix is a factor for success in the Bangladeshi clothing industry. The research results address three groups of companies. Companies with a more developed brand name place more importance on advertising in the marketing communications mix, while the second and third groups of companies give more importance to personal selling. Differences between the groups are obvious, and these correlate to the development of a brand name. The ready-made garment (RMG) industry of Bangladesh started in the late 1970s and became a prominent player in the economy within a short Period of time. The industry has contributed to export earnings, foreign exchange, employment creation, poverty alleviation and the empowerment of women. The export-quota system and the availability of cheap labor are the two main reasons behind the success of the industry. In the 1980s, the RMG industry of Bangladesh was concentrated mainly in manufacturing and exporting woven products. Since the early 1990s, the knit section of the industry has started to expand. Shirts, T-shirts, sweaters and jackets are the main products manufactured and exported by the industry. Bangladesh exports its RMG products...
