It is also known as structured development. The decomposition in structured development is based on functions. The development phases, namely, analysis, design and implementation are sequential. Maintenance is not thought of until the software is delivered to the end user. It is a general scenario that by the time software is delivered the requirements have changed or the technology has advanced. The customer is in a fix; she cannot use it or throw it due to the investment made on it. This potential obsolescence and the need for immediate maintenance is called post-delivery syndrome. This report identifies the causes for post-delivery syndrome in the traditional method and then discusses how the impact of post-delivery syndrome is reduced in object-oriented development.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"355 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124481832","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 Prototype Verification System (PVS) specification language and tool developed at SRI International was used for this study.

However problems occur with fast and consistent evaluation of these images because multiple tool wear marks exist in various shapings. The idea of using neural networks to process optical sensor data seems to suggest itself because they are tolerant to errors and able to learn by teaching various frames. The design and optimization of a structural model based on a neural network for the evaluation of optical sensor data as an application of neural networks in manufacturing engineering is explained. Results of this application of neural networks during training phase as well as the ability to generalize are shown.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128522517","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 dream system plays back high resolution at full color and full speed. The simple answer to the problem of image transport, playback, recording and storage is digital compression/decompression, but that's where the simplicity ends. Digital images are the target of playback, but come at a price. The limitations of digital images are the bandwidth to transport, compress, capacity to store, decompress and bandwidth to playback and record. Standard systems can do some of the compression/decompression with standard components. First, there are the graphics subsystem, storage, software, firmware and the main CPU. Each of these components has limitations based upon bandwidth. Second, there's software decompression which provides the most flexible method for playback at a reasonable cost. The limitations of software decompression are also seen in bandwidth analysis. Software compression is harder than decompression and can require great amounts of patience. So what's the solution to these limitations? The solution for some users is image compression while others need decompression. Deciding when you need a video codec is difficult. The right digital image processing method should become clear as one type of compression and decompression find their way on enough systems to form a critical mass.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"72 3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116250940","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}

When this happens, time to market is often extended because of the need for product redesign in order to improve manufacturing yields and quality or to lower product costs. One of the ways to reduce the number of product design iterations, or post-prototype engineering changes, is to design both the product and the manufacturing processes simultaneously. This requires involving all of the organization's pertinent engineering disciplines, in addition to marketing and support functions, right from the start of the project. This type of team development activity is usually referred to as concurrent engineering (CE) or integrated product development (IPD).<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116543554","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}

It has two objectives: a speed regulation-the driver sets a cruising speed, the vehicle reaches that speed and keeps it; a distance control-when the AICC vehicle detects a target vehicle, it decides whether it is necessary to modify the actuator instructions so as to place itself at a safe distance behind the vehicle in front. These two operating modes are permanently active and must satisfy subjective criteria of comfort while ensuring a high robustness in control. These constraints are one reason why we had a hybrid approach in the conception of the regulator. Indeed, a classic type of control (by internal model) ensures a deceleration/acceleration regulation of the vehicle; the deceleration/acceleration instruction being generated by a controller based on fuzzy logic methods. This original hybrid control guarantees the robustness criterion even if there is a variation of the structural parameters such as mass, and if there are model errors as well. It also enables the driver to personalize the running of his vehicle by selecting a driving style (\"comfortable\", \"sportslike\", ...). With the controller thus conceived we obtain quite satisfactory results within the desired limits of use.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1994-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115449132","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}
