With the current Web3D document format, users are forced to choose certain document formats to use, either during development with a particular tool or when it will be displayed in a browser. Only one format that can be processed by any browser at one given time. This raises the main problem of not allowing users to display a variety of objects with different formats in their browser. For this problem,...
The resource allocation is an essential aspect of Data Center performance. The strategy between dynamic and dedicated resource allocation have objectives in performance and reliability. The performance consists of workload, usage, and processing performance. The study works in workload performance test in dynamic resource allocation. The research present the correlation between load handling memory...
The increasing implementation of various platforms and technology of information systems also increases the complexity of integration when the integration system is needed. This is just like what has happened in most of government areas. As we have done from a case study in Sleman, a regency of Yogyakarta Indonesia, it has many departments that use different platform and technology on implementing...
Data Center systems are required to have high availability in order to meet the continuing needs of the user. If the server or application in which a failure or require maintenance, the virtual machine will be migrated to another server in the cluster are still available. The role of shared storage is very important here to keep a virtual machine that can continue the work and do not lose data on...
Previous research [2] have developed an aspect orientation agent framework based on Aglets. Aglets [1] is an object orientation agent framework. Aglet have transformed from object orientation (OO) to aspect orientation (AO) approach. The transformation process is called refactoring. Crosscutting concerns (CCC) [3] is problems behind of refactoring process. This study is a step to prove the AO Aglets...
Agent framework such as Aglets has crosscutting concern (CCC) that is legacy from object oriented (OO) programming. Refactoring is needed to make a clean agent framework from the problems. Aspect mining and aspect identification is an important process that has to be conducted in refactoring process. Aspect implementation can be conducted after aspect mining have been succeeded to identify CCC. This...
Software agent system so far has been developed using object-oriented (OO) approach. In fact, OO analysis and design can not fully model mobile agent system. The main problem is crosscutting concerns (CCC) which makes modularization of program can not be clean. Aspect-oriented (AO) approach offers a solution for CCC problems in OO approach. This paper discusses AO approach used to modify an OO agent...
With the growing of Internet, an user QoS support for Internet application will play an important role for the success of this emerging technology. Unfortunately, Internet connection in such circumstance is often not reliable, causing difficulties in accessing information sources on the Web. In this paper, we present an approach that does not only enable the user QoS integration into Internet application,...
A fractured flanged thermowell was received for analysis. The fracture was located at the root of “U” insertion/immersion length which was welded to the flange. The failure of flanged thermowell was attributed to the vortex-induced fatigue. The failure was initiated by the weld failure to withstand the fluctuating load resulted from vortex after years of service. This weld failure then created stress...
