MOSFET is an important component of the driver, temperature occurs in its different parameters such as carrier mobility. The vertical cavity surface emitting laser (VCSEL) is managed by equations of continuity which describe optical and electrical behaviour. The VCSEL parameters depend also on temperature. This is why a thermal model has been added for showing the thermal exchange between VCSEL and other connecting components. VHDL-AMS language allows to describe these different multi-technological phenomena: electrical, optical and thermal.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114864226","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}

As a criterion of usage of the LonWorks networks under soft real-time requirements we assume that either the probability of collision, or the jitter of the access delay must be bounded and small enough. The arguments for selection of the unacknowledged service as the most suitable for real-time services are put forward. The simulation results of the collision rate and the mean access delay as a function of the offered load are presented. The delay jitter for light traffic load is evaluated. Two analytical models for the probability of packet collision are suggested. The one is based on the classical approach and used for light traffic conditions. The other is employed for steady-state heavy load. The conclusions present recommendations for designing soft real-time applications using LonTalk/EIA-709.1 channel.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"75 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117151063","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}

As a case study, it has been implemented a space vector modulator (SVM) for a three phase voltage inverter.

Nagasaka","doi":"10.1109/ICIT.2003.1290812","DOIUrl":"https://doi.org/10.1109/ICIT.2003.1290812","url":null,"abstract":"In the discrete event system such as a flexible manufacturing system, many kinds of work exist together in one system. Each processing is done by the shared resource. The flow of each work mutually becomes an intertwining net structure. The shared resource will be occupied when congestion occurs by the flow of a certain work, it influences the flow of other work, it generates new congestion, and it spreads to the entire system. As a result, it falls into the situation where processing stagnates in the entire system. Therefore, controlling so as not to cause congestion in the flow of each work is indispensable. However, because it differs from single flow, and the bottleneck of the flow of each work changes by the ability distribution to each work in the shared resource, it becomes very complex. Then, the authors propose the approach for achieving the entire flow analysis for the discrete event system with the net structure and the shared resource intersection, by deriving the relational expression of I/O of which the parameter is the ability distribution of one shared resource to each flow, and connecting this one by one. And, the application to the control that improves the performance of the system is examined.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128060310","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 Internet technology is providing this accessibility with great benefits to the industry. One such demand is to access an Alien-Bradley SLC 500 family programmable logic controller (PLC) through the Internet using any available standard Web browser. This remote access capability provides real-time data acquisition to monitor and control devices that are connected to the inputs/outputs modules of the PLC. This paper presents a novel scheme to provide real-time accessibility to Alien Bradley PLC to control equipment without using any dedicated licensed software that runs as a tool for the Web server. Microsoft .NET programming technology has been used to implement the novel scheme. It involves two steps. The first step is to read and write data from the PLC SLC 5/03 using Visual Basic .NET (VB.NET) programming language. In the second step, the SLC 5/03 data is displayed on the Web page \"monitoring and controlling\" as a HTML page, using Active Server Pages .NET (ASP.NET) through the Web Services. The Web server that has been utilized in this project is the Internet information services (US 5.0) under the Microsoft Windows 2000 Server.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126960826","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 proposed topology enables decreasing of switching losses and limits the possible short circuit current through the transistor leg when its control signals temporary overlap. Both features make a construction of high power converters possible. In spite of an increased number of controllable power switches and the use of split choke, the converter's operation relies on a commercially available PFC controller (L4981). Due to the shifted pulses for the upper and the lower switches in the bridge the input current ripple and consequently the output voltage ripple are reduced. Based on a described principle an experimental model with nominal output power 1 kW has been built. Its functionality has been verified by measurements and harmonic analysis.","PeriodicalId":193510,"journal":{"name":"IEEE International Conference on Industrial Technology, 2003","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2003-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126115160","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}
