The emerging methods help us to capture both the subjective judgment and incomplete information and data in decision analysis under uncertainty. The type of method to be used for a problem depends on the situation. Although, the emerging methods appear to address uncertainty very well, problems are usually encountered. The emerging methods involve complicated mathematics, which are fairly difficult to understand and handle for the average transportation and pavement engineer. As the sample space grows, it becomes very difficult to handle and analyze uncertainties using the emerging methods. The solution becomes difficult and labor intensive. The availability of software will be a very promising step. Some of the emerging methods like influence diagrams and valuation-based systems handle asymmetric problems.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"137 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131524666","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The addition of a bus state analyzer and appropriate software can further enhance a host development system's usefulness without significantly impacting the complexity of the emulation/debugging system. Most importantly, the background debug mode allows the actual microcontroller in the target system to emulate itself providing, perhaps, the most accurate form of emulation.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123022588","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A 1985 Ford Lynx is the subject car. The design conditions are Orlando's 1% mean dry and wet bulb temperatures. The cooling load temperature difference method is used to calculate the heat gain using August data at 28/spl deg/ north latitude. To reduce the required power for the compressor, the thermal resistance of the vehicle walls, floor, roof and windows is increased to reduce the car heat gain. The design condition set points in the car are 78/spl deg/F and 40% relative humidity. A heat pipe is installed around the cooling coil to increase the latent heat capacity of the system. Additionally, a heat pipe between the exhaust and ventilation air streams pre-cools the make-up-air. The peak internal car temperature, while parked in direct sunlight, is limited to 110/spl deg/F by a ventilation system forcing outside air through the car.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121150418","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electric vehicles make ideal urban-commuter vehicles, for driving to and from, and within a city. However, electric vehicles are currently manufactured only in low volumes, and consequently the price of most commercially available electric vehicles remains high. It is possible, however, to build, an electric vehicle by \"converting\" a gasoline-powered vehicle, that is, replacing the internal combustion engine in an existing gasoline powered vehicle with an electric drive-train. This process is called \"electric vehicle conversion\", and has become popular among hobbyists, schools, and clean-air enthusiasts, as a means of providing an immediate solution to clean-air transportation. Many of the commercial electric vehicles sold in the USA are electric vehicle conversions. This paper addresses the design considerations involved in the conversion of a gasoline-powered vehicle to electric. Discussion of the various design elements in an electric vehicle conversion include: removal of internal combustion engine and related parts, choice of electric vehicle components, installation of electric vehicle components, and integration of electric vehicle accessory systems. For practical purposes, this paper limits consideration of EV components available at a cost that reflects high-volume production.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128851073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is especially true in communication circuits, such as pagers and cellular communications devices. In these cases the simultaneous presence of RF and digital circuitry increases the severity of coupling problems. In the paper an integral equation formulation is used to analyze closely-coupled microstrip transmission lines. A method of moments (MOM) solution is implemented utilizing basis functions which incorporate appropriate edge conditions for current components, allowing for close-form evaluation of spatial integrals. In contrast with earlier subdomain basis MOM solutions, greatly improved accuracy is obtained using far fewer terms. Results in the form of propagation factors and current distributions are presented for several modes, and are compared with the results of other techniques. These results are used as a basis to formulate several \"rule of thumb\" design guides for RF circuits to minimize coupling and cross-talk problems as far as possible. Other strategies for minimizing coupling in RF circuits are also discussed.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128518040","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The importance of these results has triggered the development of many approaches which try to determine an \"appropriate\" network size for a given problem. Although it has been demonstrated that most of the approaches manage to find small size networks which solve the problem at hand, it is quite remarkable that the generalization capabilities of these networks have not been explored thoroughly. In this paper, we propose the coupling of genetic algorithms and weight pruning with the objective of both reducing network size and improving generalization. The innovation of our approach relies on the use of a fitness function which uses an adaptive parameter to encourage the reproduction of networks having good generalization performance and a relatively small size.","PeriodicalId":341055,"journal":{"name":"Proceedings of Southcon '95","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116201070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
