Peak to average power ratio (PAPR) of an OFDM signal is very large. When such a signal passes through high power amplifier, the signal gets nonlinearly distorted. This causes bit error rate (BER) degradation of the OFDM system and also results in spectral regrowth. Multipath fading effects also deteriorate the signal to high extent. Our proposed system takes care of both these factors and thus improves overall performance of the system.","PeriodicalId":353966,"journal":{"name":"2011 6th International Conference on Industrial and Information Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131214620","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}

A model based design approach was followed. We started from a state chart model developed for a prototype elevator with three floors. Extension of the model for a variable number of floors was considered. Controller for the prototype system was implemented in ladder logic on a PLC and the limitations of that approach with regard to re-configurability were identified: viz., in the extension of elevator controller for ‘N’ no of floors. Next VHDL code was developed for a reconfigurable elevator controller where, by changing a variable corresponding to the required number of floors, the suitable code can be generated. The controller thus generated can be implemented in an FPGA. The method was successfully tested on a Xilinx Spartan 3AN FPGA.","PeriodicalId":353966,"journal":{"name":"2011 6th International Conference on Industrial and Information Systems","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133280156","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}

After a decade of deployment and platform integration, it stands ready to revolutionize the internet, networking, and the telecommunications industry. With the increasing number of networks, router performance needs to be upgrade with time. However with the present global routing table about 3k many routers face difficulties of handling the routing table. Ipv6 networks also blooming the internet gradually, which is a must to cater the IPv4 depreciating issue? Routing table handling issue may be huge with the IPv6 because the huge address space will cause for many routes. Multi-homing becomes the key issue with such implementation in future.

The conductivity, loss tangent, permittivity and the activation energy were calculated and used for the analysis. It was found that the conductivity improved slightly with heat treatment and neutralization process. However, during one week ageing, the conductivity improved significantly.

Still some paths are left untraveled. This paper presents an attempt to model emotions as a complex system based on the hypothesis that mind state can be considered as an emergent phenomena resulting from autonomous, interactive, elementary entities called emotions. Inspiration for our approach is found in Buddhist philosophical concepts about thought formation by combination of emotions. Multi Agent Systems (MAS) technology has been used for the realization of above emotional model because interactions and emergence are intrinsic features of MAS. Capabilities of the model are exposed through a virtual agent application called EME who perceives, understands, uses and expresses emotions. Evaluation of the agent implementation has shown good results in achieving emotional intelligence with enhanced quality.","PeriodicalId":353966,"journal":{"name":"2011 6th International Conference on Industrial and Information Systems","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116488517","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 battery circuit is represented as equivalent resistance and reactance in the equivalent circuit of the generators and such equivalent values are functions of the dc charging voltage, current and control angle set in the converter. Apart from the conventional Phase Angle Control, other firing control schemes namely Extinction Angle Control and Symmetrical Angle Control have been considered for the operation of the converter. The suitability of each of these control schemes for specific load conditions is discussed with examples.

The proposed channel allocation scheme mainly reduces the interference between femto/macro cells. Moreover, optimal channels are allocated to users such that they communicate through the channels which have maximum normalized channel gain for them. Further, here we cooperatively optimize macrocell and femtocell uplink rate and power for each user since most of the work up to now considers resources in one scheme. Thus a joint approach is more reliable. As an optimization algorithm, non-cooperative game theory approach is introduced. Further, the objective function is defined as a capacity maximization with pricing as a monotonically increasing function with user power. Thus this algorithm optimizes both power and rate for all the users in the system.","PeriodicalId":353966,"journal":{"name":"2011 6th International Conference on Industrial and Information Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125780346","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}

Although much research work focuses towards the novel applications there is less concern about the performance of the device. During the last decade the rapid development of technologies has leveraged the power of storage and access capabilities. Therefore, it is significant to analyze the I/O performances of different storage devices utilized for mobile devices. A crucial factor in this connection is consideration towards the performance of algorithms for data access latency. To minimize data access time, it is significant to consider data access pattern, and the specific native characteristics of the storage media. This paper contributes towards identifying the specific characteristics over different Storage Media.","PeriodicalId":353966,"journal":{"name":"2011 6th International Conference on Industrial and Information Systems","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132325715","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 controller synthesis requires the LPV plant model which is obtained by linearisation of the modelling equations, to be in an affine form. However, the LPV representation of the quadrotor dynamic is not affine; hence it has been transformed into to a convex polytopic form using Tensor Product (TP) transformation. The H∞ self gain scheduling control method has been applied to obtain a LPV controller which is tested on a simplified nonlinear model of the quadrotor. The LPV controller performance was compared with a separate H∞ controller. The LPV controller exhibited significant close tracking capabilities with respect to the H∞ controller.","PeriodicalId":353966,"journal":{"name":"2011 6th International Conference on Industrial and Information Systems","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126931141","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}
