It solves the problem of measurement of low currents (in order of nA) from electrochemical biosensors. However the sensitivity of integrated measurement system, which process output currents from biosensor, has to be in order of pA. There are leakage currents and noise constraints which could be avoided by on chip solution. The on-chip solution allows direct chip connection on the basic ceramic plate of biosensors. It means the idea is similar to hybrid integrated circuit. Main advantage of this solution is separating sensitive low potential and low current ASIC electronics placed just on the TFT sensor from control and supply electronics of portable device. Additional advantages of the sensors fabricated using TFT are low cost, small dimensions, good reproducibility, chemical, mechanical and electrical properties of electrodes and well accessible and ecological fabrication process.","PeriodicalId":355435,"journal":{"name":"Second International Conference on Systems (ICONS'07)","volume":"155 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128068311","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 [Unger, Wulff], the authors present an algorithm, which enables to build a sorted structure on top of a P2P Network in order to support searching in such systems and to reduce maintenance times. Based on this structure, a routing mechanism that allows the user to send messages between two peers in finite time will be provided The current work adopts ant systems as introduced by Dorigo, Maniezzo and Colorini and looks for alternative paths near to the optimal route in case of congestion conditions. Although ANTs take advantage of collaborative behavior and sign the closest paths, it is also possible to rapidly saturate the communication channels between source and target nodes. Therefore, a load balancing criterion is considered, as well.","PeriodicalId":355435,"journal":{"name":"Second International Conference on Systems (ICONS'07)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128737107","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 this paper, we revisit this problem and propose a decision tree classifier system that uses binary search trees to handle numerical attributes.

To overcome these shortages, we propose to supplement 3D CVEs with mobile devices.

As such, topologies typically become very complex and in their layout criticality a major topic to be considered. Analysis of almost one hundred different topologies of vehicle manufactures worldwide led to the conclusion that less than 50 % of these layouts had been non-critical, if tolerances of all the parameters involved had been considered in their realistic worst-case scenario. C&S group developed a methodology based on electrical network topology components modelling for a couple of years together with the major German vehicle OEMs. As such, line models had been developed along with other models for the components being involved such as transceivers, termination coupling circuits, common mode chokes, electrostatic protection elements, etc. Along with the OEM specification of the desired topologies, simulations of these modelled topologies had been executed. The result of the simulation shows the electrical signal behaviour of the communication passing through the network. Signal distortion emerges due to the discrete components and the topology geometry itself and leads to signal ringing and reflections which may corrupt the individual bits to be transmitted and received. C&S simulation technology observes these corrupted bits and identifies the reason leading to the problem observed.","PeriodicalId":355435,"journal":{"name":"Second International Conference on Systems (ICONS'07)","volume":"111 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123438139","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}
