The Adaptive Network Based Fuzzy Inference System is used to synchronize the time of duration and phase angle of the traffic lights, and also tries to maintain the maximum possible velocity of the vehicles traveling on the road. The model is simulated in Matlab software and the results are evaluated at macroscopic level with the fixed time model currently operating in Bogota Colombia.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125210283","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 radio frequency identification system used to security check in a University is presented in this work. In this system several autonomous embedded sub-systems are included, which are placed at different entrances at school. Every embedded sub-system has a link up to a master control that registers every event at the entrance. This master control has the command to close or open any entry at any time if a case of emergency is occurred.A detailed analysis about the elements that are included in this autonomous access control is presented. Some important aspects of this system are also presented. Conclusions and perspectives are presented at the end of this work.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128086825","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}

We suppose that in a botnet involved in RFI attacks, the attackers (host that launch the attack) are web servers compromised since the natural format of the attack and the tool (remote file to include). So we go deeper identified the type of host that is the attacker through a remote analysis based on domain name, content, and dynamic ip addresses.A large botnet involved in RFI attacks was tracked by almost a year and we figure out the behavior and the kind of host are the attackers and the hosters. This track were made by one University web server logs, compared with other sources. The interesting facts founded here are related to the botnet selected to study. This botnet is formed by other kind of hosts, not web servers at all. And the tool used to compromise web server is a very general shell. Other contribution of this work is a methodology for tracking RFI botnets, that could be used in real time or for historical data.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128483271","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}

It has been observed that the researchers in the nuclear sciences area carry out the selection of the network parameters through the trial and error technique, which produces poor artificial neural networks with low generalization capacity and poor performance. It has been observed that the use of the evolutionary algorithms, seen as search and optimization approaches, it has allowed to be possible to evolve and to optimize different properties of artificial neural networks, such as the proper synaptic weight initialization, the optimum selection of the network architecture or the selection of the training algorithms. The aim of the present work is focused in analyzing the intersection of the artificial neural networks and the evolutionary algorithms, analyzing like it is that the evolutionary algorithms can be used to help in the design processes and training of an artificial neural network, in such a way that the neural network designed is able to unfold in an efficient way neutron spectra and to calculate equivalent doses, starting only from the count rates obtained from a Bonner spheres spectrometric system.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133452236","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}

An associative memory is a content-addressable structure that maps specific input representations to specific output representations. It is a system that \"associates\" two patterns (X, Y) such that when one is encountered, the other can be recalled. In the design, learning and recognizing algorithms for the neural network are implemented by using VHSIC Hardware Description Language. FPGA is used for implementation because they can reduce development time greatly, ease of fast reprogramming, low price, flexible architecture and permitting fast and non expensive implementation of the whole system.

A direct digital frequency synthesizer (DFFS) is well suited for this application because of its fast switching speed, high resolution, small size and low power. The focus of this paper is on design, analysis, simulation and implementation of a DDFS, using Altera tools. The proposed architecture uses a unipolar digital-to-analog converter (DAC). Memory size is reduced more than 75 percent using quadrant compression. To decrease the amount of hardware even further, the phase generated by the phase accumulator is truncated before it is used by the ROM. Dither is added in order to get higher spurious free dynamic range. Further reduction is achieved storing in the ROM only the difference between the sinusoidal function and the phase.","PeriodicalId":126172,"journal":{"name":"2008 Electronics, Robotics and Automotive Mechanics Conference (CERMA '08)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115055251","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}
