This framework is composed of the power and workload management, and capacity planning schemes. While an action of power and workload management is performed in a short-term basis (e.g., fraction of minute), a decision of capacity planning is made in a long-term basis (e.g., few months). This paper mainly addresses a capacity planning problem. With the power and workload management, we formulate a capacity planning optimization as a stochastic programming model. The solution is the number of servers to be installed/deployed in a data center over multiple periods. The objective of this optimization model is to minimize the long-term cost under workload demand uncertainty. From the performance evaluation, with the proposed optimization model for the capacity planning scheme, the total cost to operate the data center in the long-term basis can be minimized while the job waiting time and job blocking probability are maintained below the target thresholds.","PeriodicalId":331610,"journal":{"name":"2014 11th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"121 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124170280","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}

However, content ranking and content popularities change during time. Therefore, the caches should be updated. In addition, the number of contents to be updated should be limited. In this research, we propose a method to update contents in caches of femto-cells in FemtoCaching. The proposed method has a complexity less than the contents placement algorithm of FemtoCaching. The performance of proposed method is evaluated by a simulation.

Traditional Ad hop positioning (APS) distributed, hop by hoplocalization approaches, which work as an extension of distance vector routing in order to provide approximate position for all nodes in a network, are easily affected by network topology structure, especially in irregular network. We propose a new localization strategy to solve this problem, in which some nodes are promoted asassistant anchors, and then get the localization of all the unknown nodes used both anchors and assistant anchors. In this algorithm, the error caused by the multihopdistancevector routingis decreased by employing assistant anchor nodes in the localization process, and the globallocalization accuracy can be improved obviously. Experimental results have shown that, the proposed algorithm could improve the accuracy by 30% to 40%compared with the traditional APS distributed localization approaches.","PeriodicalId":331610,"journal":{"name":"2014 11th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"124 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123488230","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 equational reasoning is sound but not always complete in general. In our previous work, we have given a condition for sound and complete equational reasoning for OBJ specifications and have proposed the notion of local equality predicates (LEP), which is not only used for verification but also used for description of specifications. In this study, we propose a method to prove termination and confluence of specifications with LEPs. Termination and confluence are important properties of term rewriting and are parts of the LEP condition. By using the proposed method, we can use nested LEPs for large and complex modules.","PeriodicalId":331610,"journal":{"name":"2014 11th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125226837","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}

It is often difficult to separate the tumor region from the background tissues. Therefore, tumor segmentation is the challenging problems in the computed aided diagnosis. Among many image segmentation techniques, a generalized gradient vector flow (GGVF) method is one of the popular techniques. It is based on vector transformation of the edge map of the gray scale image. GGVF introduces a non-uniform diffusion to preserve the large gradient of the boundary area and smooth the gradients caused by noise and speckles. However, the improper numerical iteration of GGVF may lead the false contours or the existing noise and finally the snake could not reach the true boundary. In this paper, the new vector field analysis for breast tumor US image segmentation is proposed. The GGVF vector field will be derived from the edge map of the original image. The algorithm analyzes the GGVF vectors in terms of the entropy of the angle of vectors in the corresponding window. The windows will be vertically and horizontally flipped, then the entropy will be evaluated again. Next, the ratio of the entropy before and after flip will be determined to be the classifier of the boundary and non-boundary. The algorithm has been tested on the real US breast tumor images with a set of ground truth images hand-drawn by radiologists. The proposed algorithm is compared with conventional edge detectors such as Sobel and Canny operator. The numerical experiments show that the proposed techniques lead to a better segmentation accuracy with the reference to the conventional edge detection.","PeriodicalId":331610,"journal":{"name":"2014 11th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"253 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134491961","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 important question then becomes which physical machines should be used first, because machines from different company or different generation may not be equally efficient in energy consumption. The energy efficiency of a server is characterized by its SPEC Power benchmark. This paper proposes two Greedy algorithms, ESO and FL-n, to determine the order of physical machines to be used in a Cloud environment such that the overall energy consumption is minimized. The experimental results show that ESO performed well when servers were from the same generation, using energy not more than 10% over the optimal ordering. FL-n provided good results even when servers were from different generation also, using energy not more than 5% over the optimal in all scenarios.","PeriodicalId":331610,"journal":{"name":"2014 11th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114210864","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}

Since the framework focuses more on the users rather than the ICT system, it identifies key milestones, activities, and stakeholders that should get involved in each of the 4 phases in the ICT project life cycle, which includes planning, realization, exploration, and evaluation. Our preliminary results from applying the planning phase of the ORBIT framework in the extension service at Dairy Farming Promotion Organization of Thailand is the ICT Context Diagram (IC-Diagram) which illustrates possible infrastructure, technology, services, and devices that should be used for accessing the system in the project. The diagram is designed in such a way that stakeholders with no IT background such as farmers, executive managers, etc., can easily understand the project idea and be ready for getting involved in the realization phase.","PeriodicalId":331610,"journal":{"name":"2014 11th International Joint Conference on Computer Science and Software Engineering (JCSSE)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125126896","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}
