The objective of this study is to provide tools for driving behaviour identification with the associated risk as regards of handling loss. This study aims to take into account the infrastructure, driver and the vehicle interactions, which are useful to evaluate this risk accurately.We propose in this paper a vehicles trajectories analysis in bend within a suitable Support Vector Machine (SVM) algorithm framework. At first, we will be interested on vehicle trajectory definition and experimental data acquisition. Then, we will make an experimental trajectories classification in order to determine several classes of trajectories. Afterwards, we will make a vehicle trajectories stability analysis in order to identify safe and unsafe fields of the observed trajectories. Lastly, one will use machine learning methods to predict failure trajectories.","PeriodicalId":308909,"journal":{"name":"2009 International Conference on Advances in Computational Tools for Engineering Applications","volume":"17 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":"131362203","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 proposed antenna is designed and simulated using the Finite-Element Method (FEM) and the Method of Moments (MoM) for two different switching conditions. The impedance bandwidth, gain, efficiency and radiation patterns of the antenna are demonstrated. It is shown that the antenna is suitable for WiMAX, C-band and X-band operation.","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":"116511409","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 is acquired by means of a multidimensional unconstrained nonlinear minimization algorithm based upon the Nelder-Mead direct search method. In doing this, we minimize the sum of squared residuals. The best fit is simply achieved by a direct comparison of the experimentally measured cumulative distribution function (CDF) of the recorded data with the set of curves derived from the model of interest. A good minimization can be reached only if the real CDF is accurately estimated. We show, particularly, that the new approach yields the best spiky clutter parameter estimation. The proposed estimator is more efficient than existing estimation methods.","PeriodicalId":308909,"journal":{"name":"2009 International Conference on Advances in Computational Tools for Engineering Applications","volume":"148 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":"123405085","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 design procedure also incorporates the specified wide band source and load impedances.

The first is done using one branch amplifier with variable load impedance and the second using LINC amplifier with Chireix combiner without stubs. Indeed, in the experimental work, an advanced load pull implementation tools is used where a computer controlled tuner is connected at the amplifier output in order to produce the desired load impedance.
