While this is true for the larger public network, the local network environment of the user is very vulnerable to denial-of-service, \"man-in-the-middle\" and other attacks that can be devastating. In this paper, we examine the issues of wireless security from the perspective of the user and the local network. We look at airlink attacks by specialized transmitters and intercept receivers. Examples are taken from the technologies used in IS-95 CDMA cellular radiotelephones and IEEE 892.11 wireless LANs.","PeriodicalId":318295,"journal":{"name":"Proceedings International Conference on Information Technology: Coding and Computing","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116027108","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 system is intended for measurement of small pressure variations and wireless information transmission. It is based on the principle of variation of the resonance frequency of a single-chip integrated timed circuit with measuring capacitance. The one-chip resonant circuit has been realised as a monolith integrated sensor in CMOS technology. The dimension is approximately 10 mm/sup 2/. The active part has the form of an absorption resonance frequency meter. Measurement, control, approximation, computation and result processing are performed on a PC. The paper deals with the theory of system design, electronic circuit connections, parasitic capacitances effects calculation, fabrication technology of the integrated passive resonant circuit, result evaluation and techniques of the PC-controlled absorption meter.","PeriodicalId":318295,"journal":{"name":"Proceedings International Conference on Information Technology: Coding and Computing","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123714958","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}

Three algorithms used in automated tracking techniques are the diverging square (DS); diverging circles (DC); and self-adaptive masking methods (SM). The observation of the tracking process over the images acquired (specifically for this study with introduced patient motion) in nuclear cardiac laboratory showed that the DC and SM algorithms perform better when compared with the DS algorithm. It was shown that the SM method gains a good tolerance of low signal to noise ratio (SNR) images and is also robust in the presence of abrupt motion.","PeriodicalId":318295,"journal":{"name":"Proceedings International Conference on Information Technology: Coding and Computing","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122480251","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 is proven that for finite source alphabets all Huffman codes are optimal maximal codes, codes, and maximal prefix codes. Conversely, the above three types optimal codes need not to be the Huffman codes. Completely similar to Huffman codes, we prove that for every random variable with a countably infinite set of outcomes and with finite entropy there exists an optimal maximal code (code, maximal prefix code) which can be constructed from optimal maximal codes (codes, maximal prefix codes) for truncated versions of the random variable, and furthermore, that the average code word lengths of any sequence of optimal maximal codes (codes, maximal prefix codes) for the truncated versions converge to that of the optimal maximal code (cone, maximal prefix code).","PeriodicalId":318295,"journal":{"name":"Proceedings International Conference on Information Technology: Coding and Computing","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122518603","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 matrix of 10/spl times/20 micromirrors uses a thermal actuated principle. The micromirror was designed using an industrial 0.8 /spl mu/m double metal CMOS process followed by one single postprocessing step and anisotropic silicon etch. The device consists of one cantilever beam supporting the mirror plate. The beam is a bimorph sandwich of aluminium and silicon dioxide enclosing polysilicon heating resistor. The control electronics contains 20-bit edge-triggered shift register with serial data entry and an output from each of the twenty stages (flip-flop). The output buffer is a driver for the CMOS switch (transfergate) which connects current (Pad Supply for the beam) to the thermal actuator (beam). The ANSYS program was used for the mechanical simulation of thermally actuated micromirror.","PeriodicalId":318295,"journal":{"name":"Proceedings International Conference on Information Technology: Coding and Computing","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128305400","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 novel technique is proposed, where the indicated procedures are combined in optimum algebraic coding. At the heart of the approach is the optimization of coordinate basis of an image representation. It is shown, that the required optimum properties have the eigenfunctions of Fisher's information operator known in the statistical theory of estimation. These functions satisfying defined criteria of a selection are called Principal Information Components (PIC). The PIC-projection technique for improvement of an arbitrary image decomposition is proposed. The given technique allows primary physical representation of an image to decrease a statistical error of its coding on noisy data.","PeriodicalId":318295,"journal":{"name":"Proceedings International Conference on Information Technology: Coding and Computing","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127538218","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}
