This algorithm extracts matched minutia pairs from input and template fingerprints by using the smallest minimum sum of closest Euclidean distance (SMSCED), corresponding rotation angle and empirically chosen statistical threshold values. Instead of using the minutia type and orientation angle, which are widely employed in existing algorithms, the proposed algorithm uses only the minutia location, to reduce the effect of non-linear distortion. Experimental results show that the proposed method has higher accuracy with improved verification rate and rejection rate.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125430684","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}

Possible perspectives of application include the automatic delineation of areas on the cerebral map. One of the main aspects considered in this work is related to the fact that tissue classification obtained through Kohonen Networks is achieved by taking in account the tissue and its associated neighborhood. By this way, it is possible to argue that the obtained characterizations are sustained in the topology and geometry of the human cranium.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126555965","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}

Active Noise Control (ANC) systems are important active solutions to this problem, especially hybrid systems, which join the advantages of both feed forward and feedback systems, reducing their disadvantages. This system has shown a satisfactory performance in several studies made by various authors. However, results are almost always presented in terms of ideal conditions, which makes the characterization of the system incomplete. In this article, we propose a series of parameters and tests to evaluate the performance of a hybrid active noise control (ANC) system with acoustic feedback and online secondary path modelling within the lines of a non-ideal simulation environment.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128668714","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 singular protocol has variables like amplitude, frequency and continuity of the audio signal. Each sensor is made off a transmitter with its receptor of infrared signal. Once we have developed the sensor, we proceed to calibrate it until reaching the desired range. The audio generator stage is an a stable oscillator that changes its frequency depending on the signal that is received by the sensors. The switching stage has been designed by a transistor that works as a switch, working in the cut and saturation state. The amplifiers are designed for little signals generating two levels of amplitude adequate to the human ear. The first zone includes frontal sensors to detect obstacles and regulates the signal frequency for the sound in both headphones depending of the distance of the obstacles. The second zone includes surface sensors; these generate a change in the signal amplitude in the sound for headphones in two values, a high one, and a low one, it depending on whether or not there is a vacuum in the surface. The third and fourth zone includes lateral obstacle’s sensor calibrated at a specific distance that modifies the audio signal corresponding to each headphone in an independent way between two levels, a continuous and a discontinuous one.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125844034","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 analyzed robot has 16 degrees-of-freedom: five for each leg and three for each arm, actuated by sixteen digital servomotors, like those used in aero-modelism. Each leg is a serial kinematic chain that uses three degrees of freedom to control the position of the foot, and two more to orient it,resembling a human ankle. Unfortunately, this ankle has been designed with an offset that prevents a direct decoupling of the position and orientation of the foot, situation that generally leads to the lack of a closed form solution in most cases. The proposed solution deals with this problem; it uses a geometrical approach that effectively solves the inverse kinematic problem by means of an analytical algorithm.","PeriodicalId":292855,"journal":{"name":"2009 International Conference on Electrical, Communications, and Computers","volume":"141 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127326983","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}

By this methodology the aim of the system design process with minimal computer time is presented as a transition process of some dynamic system that has the minimal transition time. The optimal position of the control vector switch points was determined as a principal characteristic of the minimal-time system design algorithm.
