The models’ implementation was made using fuzzy logic. In fuzzy logic, the cluster technique was used to decrease the number of rules to use in the identification. This technique is opposed to the conventional method which requires a considerable number of fuzzy inference rules to approach the model. In the consequence of fuzzy model, different techniques are used to implement Takagi-Sugeno type rules. By other hand, we implemented the Neuro-fuzzy modeling methods, which let represent the non-linear system and at the same time a system with some learning degree using different topologies. By comparison the goodness of each method is obtained.","PeriodicalId":371526,"journal":{"name":"16th International Conference on Electronics, Communications and Computers (CONIELECOMP'06)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116442864","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 application in fluorescence spectroscopy is mention and the sampling processes as well as the different sampling techniques are briefly studied. The approach makes use a Digital Signal Processor (DSP) and a Personal Computer (PC) to demonstrate the technique. The DSP communicates with the computer via a standard serial port to receive commands and to transmit data. In addition to the sampling technique, the DSP also applies a method of noise suppression by averaging the sampled digital signal.

In recent years, research in wireless communications has focused mainly in the utilization of spatial and temporal diversity in both transmission and reception by means of antenna arrays at both ends, in order to achieve this increase in channel capacity. These MIMO (Multiple-Input Multiple-Output) systems, to work properly and guarantee its potential advantages, demand powerful signal processing procedures so as to recover the signal transmitted by the antenna arrays in the best possible way. Among the different signal processing algorithms that exist for these MIMO systems, the BLAST algorithm has come to be a potential alternative for its excellent complexity-performance tradeoff. This system has different realizations. In this paper, we concentrate on a Least-Squares based VBLAST architecture and propose a simple means for improving further its performance. Indeed, with the concatenation of a conventional convolutional coder, the overall performance can be increased in 3 dB while increasing the complexity in an acceptable way. Results are also compared to the quasioptimal Closest Point (CP) decoder. It is shown that our proposed system outperforms the CP algorithm by 3 dB for the same antenna arrays, and for the same computational complexity, our proposed system is better by 4 dB.","PeriodicalId":371526,"journal":{"name":"16th International Conference on Electronics, Communications and Computers (CONIELECOMP'06)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130433886","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 open issue, both from the technical and economic points of view, is to identify the requirements and the necessary steps to migrate from 2G to 3G mobile cellular networks. A number of mobile network evolution strategies toward 3G were generated and evaluated using the TERA model.

Furthermore, visual event detection offers information about physical events occurring inside the scene. This article presents a low cost algorithm for visual event detection. The proposed algorithm is based on the partial decoding of the JPEG (Joint Picture Expert Group) flow produced by the IP cameras hardware and the analysis of the DCT (Discrete Cosine Transform) coefficients on contiguous frames. Two are the main advantages of this algorithm: It runs over a reduced memory space and it is inexpensive in terms of CPU resources.
