The ATM-SMX is modeled as a discrete-time finite-buffer single-server queueing system, where two types of traffic represent the inputs of the multiplexer: (1) nonreal-time loss-sensitive traffic; and (2) real-time loss-insensitive traffic. The authors assume that there are N identical type 1 sources each modeled as a Bernoulli process. The authors also assume that there is a single type 2 source modeled as a periodic batch arrival where the batch site follows a general distribution. All the slow-speed inputs of the ATM-SMX are multiplexed onto a single high-speed output link, and the service rate is constant. The authors adopt a scheduling policy which suits the characteristics of these two types of traffic. An exact analysis is developed to obtain the waiting time distributions and cell loss probabilities for both types of traffic.","PeriodicalId":135973,"journal":{"name":"Proceedings of 28th Southeastern Symposium on System Theory","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133297221","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}

Numerical results comparing performance of LLR and MLLR in, terms of blocking probability are introduced.

These systems are discussed in this paper with a focus on the inverter output stage. The inverters considered include conventional six- and twelve-pulse square wave, pulse-width modulated, and multi-level inverters. Current- and voltage-controlled inverters are considered where appropriate. Each of these inverter topologies has been successfully applied to a number of applications such as adjustable-speed motor drives and static VAr compensators but only limited information is available concerning the use of various topologies with active power conditioning equipment. This paper is intended to assimilate the information that is available in a convenient manner so as to provide the basis for continued research in this area.","PeriodicalId":135973,"journal":{"name":"Proceedings of 28th Southeastern Symposium on System Theory","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1996-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132634334","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}

They can help make this difference by partnership with educational institutions and universities, and taking advantage of the power of diversity these can provide. Acceleration of innovative ideas and production requires state of the art technologies and closer collaboration between academician, government and the private sector. It requires all engineering disciplines work effectively and achieve excellence in \"doing it right for the first time\". The ability to reach these goals will determine the next generation of winners and losers.
