The impulse response can be obtained using a clever analysis of the Empirical Transfer Function Estimate (ETFE). It is shown that the impulse response estimation is asymptotically unbiased with a bounded variance. The acoustic parameters are determined numerically from this estimation and according to their definitions. The performance of the methods is shown by an example employing a song as a test input instead of the usual pink noise. Since the method uses a reduced number of data in the input and output vectors, the computation time is reduced without significantly increasing the error with respect to the ideal response.","PeriodicalId":359559,"journal":{"name":"2010 IEEE ANDESCON","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127522283","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 main purpose is to study the behaviour of each technique for a given reference current. In addition, some simulations are presented in ATP. The reference signals tracking for different current control techniques and different converter topologies is shown by these simulations. The control techniques are compared based on some criteria such as maximum steady state error and effective error of the current generated by the inverter.","PeriodicalId":359559,"journal":{"name":"2010 IEEE ANDESCON","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127617403","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}

For instance, placing items in a warehouse where it is essential to take advantage of the available space and meet the production requirements. Similarly, the parking slot allocation for automobiles in a car parking in which there are occasions where a lack of proper distribution of the automobiles exist. In the same sense, the space allocation for crops in a land for cultivation in which it is important to take into account factors and features such as humidity and pH. In this paper, an intelligent organizer of objects is presented using Genetic Algorithms (GA) and Hill Climbing (HC) to solve the space allocation problem in a Warehouse, a Car Parking and a Land for Cultivation. Also, a technique that organizes objects randomly in the space was implemented to compare results with the intelligent techniques. Several tests were performed to check the proper system operation and then performance tests under different conditions are shown comparing the results between the intelligent techniques and the random technique. Finally, advantages and disadvantages of intelligent techniques to solve the space allocation problem are presented.","PeriodicalId":359559,"journal":{"name":"2010 IEEE ANDESCON","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125157024","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}
