The standard is now used by more than 50 modem manufacturers and is rapidly,spreading into Local and Remote Area Networks (LANs, WANs). Follow-on standards now being developed (such as V.34 or V.fast) use the same data compression method in different communications protocols. British Telecom developed the V.42bis standard by combining a variety of inventions and ideas into a standard called BLTZ (British Telecom Lempel Ziv). Data compression is based on tree libraries invented by Holtz in 1974, which Welch modified in 1984 into the LZW codes. British Telecom added \"Delayed Innovation\" and a limited recycling library. A built-in microprocessor monitors the compression ratio, switching compression on or off using IBM's \"Escape Character\" sequences. The output codes are stuffed into 8 bit octets and combined into packets which include error checking codes. Defective packets are re-transmitted automatically, ensuring error free data transmission.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"25 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":"130823614","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}

In most of these, logic implemented in an FPGA could have been implemented with more traditional logic devices-masked gate arrays, or MSI/SSI devices, for example. However, FPGAs were a better alternative for any number of reasons-no nonrecurring engineering costs, lower design risks, less power dissipation, faster design and production cycles, etc. In essence, FPGAs combine the high-integration benefits of gate arrays with the time-to-market benefits of a user-programmable device, and typically are selected over other logic technologies to gain these benefits.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"41 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":"133477391","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 bridged network of LANs allows stations and servers attached to separate LANs to communicate over a Fibre Channel fabric transparently, as if they were attached to a single LAN. In addition, software applications residing on direct-attached Fibre Channel nodes will be interoperable with applications on the traditional LANs.<<ETX>>","PeriodicalId":136567,"journal":{"name":"Proceedings of WESCON '94","volume":"84 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":"130306436","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}

Five of the most common forms are: hard-disk loading, end-user piracy, counterfeiting goods, software rentals, and bulletin board piracy. Many businesses and end-users do not realize the risks associated with using copied software. Not only is using copied software against the law, the work product and consequently, a company's competitive edge is at stake.

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 behavior of the Swi-Int manager is specified graphically in a knowledge graph and as a process algebra formula written in HOL. In an effort to avoid the possibility of livelock in the behavior of the manager, timing constraints are introduced into the design of the manager.
