Such cloud platforms runs Hadoop on virtual clusters with remotely attached storage. In cloud architecture with multiple geographically separated regions, virtual machines (VMs) belonging to a virtual cluster are placed randomly. In order to run MapReduce jobs, data have to be moved to the regions where the VMs reside to achieve data locality. In this paper, we propose a data-location aware virtual cluster provisioning strategy to identify the data location and provision the cluster near to the storage. The use of bio-inspired optimization algorithms are considered for optimizing the placements of VMs. Data location aware cluster provisioning reduces the network distance between storage and the virtual cluster, resulting in faster job completion times.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121307459","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}

As software development progress, the UML model became complicated. Thus, difficult for human being to trace back previously known relationship(s) between classes of the previous class diagram(s) in the present complex class diagram. Tracing back previous relationship(s) is accomplished by abstracting relationships among three related classes to semantic equivalent relationship between two of the classes. Abstracting class diagram aid in checking consistency, reverse engineering and facilitate model understanding. This article presented abstraction rules of a class diagram using a logical approach. The result was evaluated using a case study of hotel management system, and the rules were found to be reliable and useful.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131351104","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}

Thus, the data stored in computer system contains a very critical and important information and therefore, there's a critical needs to put more effort in handling of such data. Based on the traditional method, the most popular authentication way for computer security is using alphanumeric password. However, this type of authentication method come with few drawbacks. In recent years, many new methods have been developed by researchers to overcome the limitation of the password authentication, and one of the most popular method is known as graphical password, which utilizes picture as password instead of the alphanumeric string. Hence, this paper propose a new graphical password framework and method to be used in mobile-platform.

The goal of the algorithm is to learn to identify what classes are most relevant to include in the diagram, as opposed to full reverse engineering of all classes. This paper focuses on building a classifier that is based on the names of classes in addition to design metrics, and we compare to earlier work that is based on design metrics only. We assess our condensation method by comparing our condensed class diagrams to class diagrams that were made during the original forward design. Our results show that combining text metrics with design metrics leads to modest improvements over using design metrics only. On average, the improvement reaches 5.3%. 7 out of 10 evaluated case studies show improvement ranges from 1% to 22%.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115019662","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 scheme is inspired by the natural bee communications paradigm. The mobile agent concept is adopted from the bees' mobility behavior for network traffic information exchange among the VANET nodes aiming for a quality transmission of data packets. This is accomplished by calculating the corresponding QoS provision values based on certain QoS metrics threshold to determine a reliable and stable route between a source (beehive) and the destination (food source) node. The proposed scheme shows a better performance as compared to the AODV and DSR protocols in terms of packet loss and network throughput.","PeriodicalId":439852,"journal":{"name":"2014 4th World Congress on Information and Communication Technologies (WICT 2014)","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126441573","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 large scale connected representativeness of access to and often ownership of mobile devices opens many doors to innovative, far reaching mobile-based applications and services. This near ubiquitous access, however, is characterized by an entirely new set of challenges as different legacy devices and cutting edge smartphones make up a cornucopia of end user realities. In order to reach as many end users as possible through the devices that they already own and are comfortable with, channel agnostic access is needed that would support the different mobile access channels using a variety of communications protocols.
