A number of 16 eigenfrequencies and eigenmodes are evaluated for a thyroid geometric model excited by ultrasounds. The malignant tissue was modelled by spheres with different diameters. The spatial distributions of the acoustic eigenmodes are in accordance with blood supplier positions. Blood supplier efficiency and local temperature will decrease as a result of nodules or cysts. The acoustic field eigenfrequency for the same propagation mode is bigger when thyroid has a malignant nodule. Efficiency of ultrasound diagnosis and thyroid treatment will be increased by knowing these modes and frequencies.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129040971","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}

Therefore it is difficult to fabricate both sensors and readout electronics in a planer process, and hybrid approach such as mechanical bump bonding have been used. Recently we have developed monolithic radiation detectors based on a 0.2 µm Fully-Depleted Silicon-on-Insulator (FD-SOI) CMOS technology. It has both a thick, high-resistivity sensor layer and a thin LSI circuit layer in a single chip. To shield the electronics part from the sensor region, we have created a buried well region under the buried oxide (BOX) layer of the SOI wafer. Furthermore we are trying to integrate another circuit tier by using a μ-bump technique of 5-µm pitch. This kind of vertical (or 3D) integration is especially important in the pixel detector, since it can increase functionality of a pixel without increasing the pixel size.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129060774","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}

In this sense, to implement maximum wind power extraction, most controller designs of the variable-speed wind turbine generators employ anemometers to measure wind speed in order to derive the desired optimal shaft speed for adjusting the generator speed. In this paper it is proposed a new Neural Network Based Wind Speed Estimator for a wind turbine control. The design uses an feedforward Artificial Neural Network (ANN) to implement a rotor speed estimator, and simulated results show that the proposed observer provides high-performance dynamic characteristics.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126912824","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}

As the expanding network facilities of many service providers span a diversity of network technology, versatile QoS model would be established to become a sought-after solution. In this article we present a particular case of a QoS-aware platform design intended for the scenarios where user applications run as an integral part of a distributed Information System. While the realization is at work in progress stage, the initial implementation results have shown that the concept can be translated into a working system. Putting QoS at the forefront of design has encouraged to review some network mechanisms and revealed specific mathematical challenges. The early research results have illustrated that the proposed framework can be constructed and made usable.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123925168","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}

Despite its importance in ensuring the reliability of semiconductors, burn-in has been a major contributor to overall test cost and turnaround time. In this work we discuss the application of advanced Boolean satisfiability (SAT) techniques to generate a set of vectors or input stimuli that increases the nodal activity in the circuit and hence the elevation of its temperature. The vectors are designed to uniformly stress all parts of the circuit. Additionally, we present a SAT-based methodology where weak nodes can selectively be targeted for high switching activity in an effort to detect potential failures. Finally, SAT-based solvers are compared against generic Integer Linear Programming (ILP) solvers when handling the vector generation problem.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126210514","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 aim of this work is to evaluate the SVM performance in the recognition of a human mental task, among others. A prerequisite has been the developing of a system able to recognize and classify the following four tasks: thinking to move the right hand, thinking to move the left hand, performing a simple mathematical operation, and thinking to a nursery rhyme. The data set exploited in the training and testing phases has been acquired by means of 61 EEG electrodes and consists of 4000 time series. These time data sets were then transformed into the frequency domain, in order to obtain the power frequency spectrum. In such a way, for every electrode, 128 frequency channels were obtained. Finally, the SVM algorithm was used and evaluated to get the proposed classification. Different choices of electrodes have been considered: we found that analysing only a subset of electrodes we can get better results than considering all the 63 electrodes.","PeriodicalId":256057,"journal":{"name":"Melecon 2010 - 2010 15th IEEE Mediterranean Electrotechnical Conference","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130266110","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}
