The problem rises when potency of them is far smaller than load demand and the high difference between wind velocity profile and solar radiant intensity and load profile is happened. Its make excess electricity to be higher so the electrical production cost to be higher too. The purpose of this research is designing optimal configuration of microgrid PV-Wind turbine-Grid-Battery through optimization of load capacity to reduce excess electricity. Some parameters of optimal configuration are used to evaluate them, namely electrical production cost, reliability, CO2 coming from life cycle assessment, area of installation and unemployment reduction. Software HOMER version 2.68 Beta from NREL is used to simulate alternative configuration of microgrid. The results show that distribution total load into some sub-microgrids gives the positive impact, namely smaller electrical production cost, higher reliability, minimum CO2, relative smaller area of installation and unemployment reduction.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122822958","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}

Numerous methods and algorithms have been developed in recent years; however, there is a sensible gap between the current detection rate and the ideal one yet. In this paper, a novel multi-stage face detection method is proposed which can remarkably detect faces in different images with different illumination conditions, variety of poses and disparate sizes. The idea is to utilize a preprocessing step to filter many non-face windows by means of a skin segmentation procedure in order to boost the speed of the detection and also utilize the color information as much as possible. Subsequently, candidate windows are fed to a Local Hierarchical Pattern (LHP) generator unit where a new texture pattern is produced. Based on this pattern, a kernel probability map is calculated for each window, and by summing probabilities of all kernels and comparing it with a predefined threshold, decision is made about content of the window. This algorithm not only effectively eliminates many non-face regions, but also it is capable of detecting faces with relatively acceptable rates.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121340988","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}

Developing and controlling quality of website that response different consumer needs can affect customer satisfaction and repurchase intention. This study constructed an integrated model of customer repurchase intention in B2C e-commerce based on DeLoan and McLean's IS success model for testing the relationships among website quality, internet shopping value, customer trust, customer satisfaction, and customer repurchase intention. Then, empirical testing examines the effect of B2C website qualities on the internet shopping value and subsequent customer repurchases intention. A survey of 384 shoppers of B2C e-commerce was conducted to test a model. The model was shown a significant fit. Results showed that system quality had a significant impact on the hedonic shopping value, information quality had a significant impact on the utilitarian shopping value, and service quality had a significant impact both on the utilitarian and hedonic shopping value. Moreover, results also showed that utilitarian shopping value, customer trust and customer satisfaction had direct positive effect on customer repurchase intention.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125100385","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 problem of CI user is the inability to discriminate simultaneous incoming sounds, focusing on the desired sound (target) whilst ignoring the rest (cocktail party problem). In this research, the release of masking strategy is introduced to give a glimpse of acoustical cues for CI user to make the discrimination easier in the presence of background noise (masker). We evaluated the performance release of masking with various combinations of target sound channel vocoder (the sound that want to hear) with respect to masker channel. For further enhancement, we also evaluated spectral subtraction (SS), Ephraim-Malah, and Frequency Amplitude Modulation Encoding (FAME) to improve intelligibility of channelized sounds. The results showed that the release of masking may have improve the intelligibility on CI users to access temporal structure of waveform of simultaneous stimuli. The best enhancement method is FAME with PESQ value 1.4 and % correct word increased to 72%.","PeriodicalId":148115,"journal":{"name":"2014 6th International Conference on Information Technology and Electrical Engineering (ICITEE)","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127525068","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}
