Essentially, it is fortitude of organizations, associations, corporation of information about the enterprise concerned, for support of assessment-making process. In assimilation with that enterprises relay on DSS tools, techniques and models in order to seek recommendations in business activities and strategies. One of the most important but vast areas specified for DSS is a Group Decision Support System (GDSS), that is a kind of electronic meeting system, a collective technology design for meetings and group works via a human computer interaction for effective group decision making. Though this is a relatively new and emerging field of DSS, there remain some problems and issues to be solved in GDSS such as its requirement of real time operation, process losses, time consuming and high cost required for its group coordination etc. This paper presents a review of numerous researchers’ efforts regarding GDSS and their impacts. The rationale of our study in this paper is in twofold: first is to review the literature, highlight the shortcomings and their core ideas or strengths. Another perspective is to show a critical evaluation by comparison and contrast. The contribution of this paper is on surveying many researchers efforts pertaining to GDSS.","PeriodicalId":112416,"journal":{"name":"2009 Fourth International Conference on Computer Sciences and Convergence Information Technology","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130414408","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}

Nonuniform illumination is among one of those problems. This paper proposes a novel method for solving nonuniform illumination problem using multiresolution decomposition and a new technique called hillcreast-valley classification with adaptive mean filter to normalize illumination and detect dominant facial features, such as eyes, nose and mouth automatically. The proposed method is divided into three modules: eye detection, nose detection, and mouth detection modules. In this method, a single face image is divided into three regions: eye, nose, and mouth regions, then we use multiresolution decomposition to detect the eyes, and use thresholding to detect the nose and the mouth. For multiresolution decomposition, we decompose the eye region into small blocks and use hillcrest-valley classification with adaptive mean filter to classify each block as either a high or low-intensity region. Each low-intensity(valley) region is then decomposed into smaller blocks and each block is classified as either high- or low-intersity region. The low-intensity regions are then defined as the eyes. Finally the nose and the mouth are detected using thresholding. The method was evaluated on the YaleB face database that consists of face images taken by different illumination variations and the experimental results indicate that our proposed method achieves high accuracy rate.","PeriodicalId":112416,"journal":{"name":"2009 Fourth International Conference on Computer Sciences and Convergence Information Technology","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126997999","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 introduces a new Denial of Service (DoS) technique of GPS receivers that operates on the user segment, which is based on hidden messages from the user segment. The paper focuses on the analysis of the feasibility and covertness of using a large number of reserved bits in GPS L1C Nav navigation message to carry and transmit hidden messages, as well as of the feasibility of using expanded data types of GPS L2C CNav navigation messages to transmit hidden messages. Based on the reserved bits in GPS L1C Nav, two formats of hidden messages are designed, with mainframe and superframe as basic carrying units for transmission. Besides, the paper presents four approximate representations of DoS target areas, and probes into the position matching in DoS of GPS receivers. The research in this paper shows that it is feasible to realize DoS of GPS receivers based on hidden messages and hidden messages are provided with high convertness by transmission channels.","PeriodicalId":112416,"journal":{"name":"2009 Fourth International Conference on Computer Sciences and Convergence Information Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-11-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126487310","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}
