The size of the database determines the efficacy and speed of information retrieval. The potency of spatial query in Geographic Information Systems (GIS) is of paramount importance. It depends heavily on the query processing algorithms. When the database size increases, the processes of data retrieval gets complicated. This paper employs two types of data structures; Rectangle-Tree (R-tree) and the Balanced-Tree (B-tree) which is called aRB-Tree. These two types have been formerly merged by researchers to facilitate the retrieval of data as quickly as possible while providing efficient results. The same idea has been adopted in this paper where the aRB (aggregate RB) accelerates executing complex queries and minimizes the time consumed in searching, editing, deleting and updating any record in the spatial database. In this paper a web application was developed to test the efficiency of using both data structures. This web application utilises a medical institution database that contains locations such as addresses of physicians, clinics, hospital, labs, and radiology centres. Results of aRB-Tree are more sufficient and accurate than using each index alone.","PeriodicalId":405465,"journal":{"name":"2013 23rd International Conference on Computer Theory and Applications (ICCTA)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128972246","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}

IP fast reroute is used to minimize the time taken to redirect the traffic to an alternate path. Multiple routing configurations (MRC) is the IP fast reroute scheme under consideration. In this paper, we will discuss how to minimize the impact of the MRC recovery process on the post failure load distribution over network links. Two techniques used to achieve a good load distribution across links after failure are compared. The first technique utilizes manual link weight manipulation with MRC. The second technique is the modified MRC. Both advantages and disadvantages of the two techniques are discussed.","PeriodicalId":405465,"journal":{"name":"2013 23rd International Conference on Computer Theory and Applications (ICCTA)","volume":"118 2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126419592","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}

Ad-hoc mobile clouds, in which infrastructure software is distributed over resources harvested from machines already existing and used for other purposes, are gaining popularity. In this paper, we propose a trust management system (TMC) for mobile ad-hoc clouds. This system considers availability, neighbors’ evaluation and response quality and task completeness in calculating the trust value for a node. The trust management system is built over PlanetCloud which introduced the term of ubiquitous computing. EigenTrust algorithm is used to calculate the reputation trust value for nodes. Finally, a performance test was executed to prove the efficiency of the proposed TMC in term of execution time, and detecting node behavior.","PeriodicalId":405465,"journal":{"name":"2013 23rd International Conference on Computer Theory and Applications (ICCTA)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132401694","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 produced feature vector is used as input to a recurrent neural network (RNN) for recognition. The dynamic behavior of the RNN used to categorize input sequences into classes.

Control charts were used to construct a statistically controlled stock market prediction model to support the decision of stock investors.

Hit rate was applied as a performance measure of the quality of prediction for the suggested model. Results of predicting 900 next day stock predictions during January 2012 had a mean absolute prediction error of 2.096 LE and a hit ratio of 67%.

Unlike other approaches, which involved in questioning the users, feature extraction procedures were implemented on electrical energy consumption time series in order to extract knowledge.

Trusted and just in time information is the target. SOA serves as a bridge to pass the data logic as a black box and separate the logic of the rules to provide reusing capability. The proposed framework provides a solution when governmental agencies have common confused rules. It helps obtaining the most trusted rules.

This paper proposes a hybrid moving object detection algorithm, which combines controlled temporal scale frame difference and selective running average as a method of background subtraction. In order to overcome the main drawbacks of traditional temporal difference methods that depend strongly on the speed of the moving object, we propose a new algorithm that controls the temporal scale between successive frames to solve the problem of emptiness phenomenon, whenan object moves slowly. Experimental results show that the proposed algorithm outperforms other commonly used object detection algorithms.","PeriodicalId":405465,"journal":{"name":"2013 23rd International Conference on Computer Theory and Applications (ICCTA)","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-10-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132320990","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}
