However, so far, its impact on insulator performance is not well known. This paper summarizes the work published in the field. Based on the gathered experiences, it can be concluded that microbiological growth is unlikely to cause severe degradation of the rubber housings of non-ceramic insulators. Furthermore, it seems that the impact of growth on the insulator performance is rather low. Techniques available for detection and characterisation of growth on insulators are also described and discusses. Among those, laser-induced fluorescence (LIF) spectroscopy has been found to give good results in remote detection of micro-organisms.","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130337819","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}

This paper also addresses the suppression technique for the undesirable chattering phenomenon which usually occurs in SMC by replacing the discontinuous controller sign function with a proper continuous function. Chattering is unwanted because it leads to an excessive usage and damages the actuators and therefore the control law may become impractical. In this study, an integrated model of hydraulically actuated robot that considers both the manipulator linkage and actuator dynamics is used to provide a more suitable model for controller synthesis and analysis. The control technique is stable in the large based on Lyapunov theory. Its performance is evaluated and compared with the existing independent joint linear control (IJC) technique through computer simulation.

Achieving these objectives in end-to-end scenario is promising but challenging. In this paper, we present a novel end-to-end TCP-Friendly algorithm that uses two-step additive increase and multiplicative decrease (TAIMD) to control the congestion window using a history-based fair-share estimation. TAIMD smoothes the rate variations by using a two-step increase function and adopting a timer-based packet scheduling mechanism. Convergence performance is improved by using a second fair-share estimation based on packet loss, yet keeping the control less sensitive to the inherent short term fluctuations in the loss-based fair-share estimation. Analytically, we derive parametric relationships for TCP-Friendliness and for fairness convergence of TAIMD.

An mobile ad hoc network (MANET) is actually a collection of mobile nodes which can communicate with each other without any fixed infrastructure like the base station. AODV routing protocol adapts quickly to dynamic link conditions, it has low processing and memory overhead, low network utilization, and determines unicast routes to destinations. The main highlight of this protocol is the usage of destination sequence number which omits problems like counting to infinity problem or the formation of loops which are associated with other classical distance vector protocols. In this paper, the AODV protocol is implemented using hardware and the simulation and synthesis report of ad hoc routing protocol is presented. Implementing this in hardware will reduce the power consumption and delay time so that the mobile device's battery life time is extended in an unpredictable temporary communication network in case of an emergency like floods, earthquakes and on mountains where there is no scope for construction of required infrastructure and also helps in military applications","PeriodicalId":122994,"journal":{"name":"First International Conference on Industrial and Information Systems","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116065551","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}

Theoretical treatment at this scale differs fundamentally from macroscopic analysis, because thermal energy may take a variety of forms at the crystal lattice level, with distinctly different consequences for dissipation. These dynamical behaviors have the potential to greatly enhance control of heat transport and, for example, mitigate the effects of local heating. To a surprising degree, simple lattice models display many of the salient phenomena observed in epitaxial crystal layers. The Toda lattice is a completely integrable, anharmonic, discrete particle model, incorporating only nearest-neighbor interactions. In this paper, we employ the Toda lattice, originally developed as a model of thermal transport in crystals, to develop ideas for applying control theory to such systems. As a first result, we show that localized feedback of a small number of integrals of motion can be used to convert slow phonon modes, associated with limited heat transfer, into fast phonons modes, thereby reducing local heating.
