The research intends to investigate a high accuracy of identification the speech signal of very difficult nature that is non- stationary. Three methods are used to extract the essential speaker features based on Continuous, Discrete Wavelet Transform and Linear Prediction Coefficient (LPC). To have better identification rate three measurement methods are used: Percentage rms Difference (PRD), Correlation Coefficient (CC), and Statically Deformation Determination Coefficient (SDDC). 95% identification rate is accomplished. The presented system in this paper depends on multi-stage features extracting due to its better accuracy. The system works with excellent capability of features tracking even when the tested signals are very noisy with −32dB SNR. This is accomplished because of multistage features tracking based system using Wavelet Transform, which is suitable for non-stationary signal.","PeriodicalId":308909,"journal":{"name":"2009 International Conference on Advances in Computational Tools for Engineering Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124052694","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}

To that end, 216 models based on neural networks (NN) have been built. The database used to fit the NN's has been historical records of the traffic, meteorological and air pollution networks existing in the area corresponding to year 2000. Then, the models have been tested on data from the same networks but corresponding to year 2001. At a first stage, for each of the 216 cases, 100 models based on different types of neural networks have been built using data corresponding to year 2000. The final identification of the best model has been made under the criteria of simultaneously having at a 95% confidence level the best values of R2, d1, FA2 and RMSE when applied to data of year 2001. The number of hourly cases in which due to gaps in data predictions have been possible range from 11% to 38% depending on the sensor. Depending on the pollutant, location and number of hours ahead the prediction is made, different types of models have been selected. The use of these models based on NN's can provide Bilbao's air pollution network originally designed for diagnosis purposes, with short-term, real time forecasting capabilities. The performance of these models at the different sensors in the area range from a maximum value of R2=0.88 for the prediction of NO2 1 hour ahead, to a minimum value of R2=0.15 for the prediction of ozone 8 hours ahead. These boundaries and the limitation in the number of cases that predictions are possible represent the maximum forecasting capability that Bilbao's network can provide in real-life operating conditions.","PeriodicalId":308909,"journal":{"name":"2009 International Conference on Advances in Computational Tools for Engineering Applications","volume":"30 4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125805438","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}

E-learning platforms are evolving in a rapid way into modular platforms based on service-oriented architectures providing flexibility and services reusability. In this work, in one hand, we highlight the importance of securing e-learning platforms: we start a review of the first e-learning generation where the focus was on sharing learning content, the second generation that added sharing of learning objects between different platforms, and the third generation based on service-oriented architecture, where content, tools, and functionalities are available for reuse in a dynamic environment. On the other hand, we explain the security challenges, both, the first and the second e-learning generations might be facing, we then discuss the service-oriented architecture security challenges in distributed environments, and finally, as a conclusion, we propose a security service-based architecture to securing third e-learning generation.","PeriodicalId":308909,"journal":{"name":"2009 International Conference on Advances in Computational Tools for Engineering Applications","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127042634","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 paper presents the design and development of a computer-based feedback control system for an RF remote-controlled robot. The robot is wirelessly connected to a transmitter/receiver circuit through two RF remote control units ensuring fast and reliable five-bit, two-way communication. The transmitter/receiver circuit is connected to the parallel (LPT1) port of a PC running a Java™ application. The program provides two functionalities for the robot: a closed-loop control system that allows the robot to automatically follow a line, and an open-loop system that allows the user to manually control the robot through a Graphical User Interface (GUI). The computer-based feedback control system is a demonstration of a reactive hybrid system where flexible computer instructions form the logic unit that controls a continuous process. The system can be easily modified to enhance the capabilities of the robot and use different control laws and principles, thus ascertaining that hybrid control systems are highly accurate, reliable, and most importantly flexible.","PeriodicalId":308909,"journal":{"name":"2009 International Conference on Advances in Computational Tools for Engineering Applications","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130663094","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}
