In this paper, the authors have focused on the stochastic analysis of an internet data center (IDC), which consists of a database main server connected to a redundant server. Observing the different possibilities of functioning of the system, analysis has been done to evaluate the various reliability characteristics of the system. The system can completely fail due to failure of redundant serve...

Storing large amounts of data in an efficient way from the point of view of very fast retrieval is an important requirement for many industries like KEMA, a company offering consulting, testing and certification in the energy business. Because their relational database could not cope fast enough with the large amounts of data involved, an alternative way for data storage was proposed, called Hi...

Recently, context-dependent access control mechanisms were established: Information about the state of a business process is combined with general knowledge about a person to grant or revoke access to sensitive data. Though being understood very well in principle, many different problems arise when context-dependent access control is realized for an application of practical relevance on a concr...

Protein-protein interactions can be challenging to study yet provide insights into how biological systems function. Targeted cross-linking mass spectrometry (TX-MS), a method combining quaternary protein structure modeling and chemical spectrometry, creates high-accuracy models using data obtained from complex, unfractionated samples. This removes one of the major obstacles complex analysis bec...

Currently there is no method, feature, or ability in securing data transmission microcontroller systems and applications with client-server scheme communication, while major modern computer using secure socket layer (SSL) for establishing communication. However, ESP espressif based has supported SSL communication to transmission, but only works on the Wi-Fi network. A single-board embedded syst...

Asterisk and Open IMS use SIP signal protocol to enable both of them can be connected. To facilitate both relationships, Enum serverthat is able to translate the numbering address such as PSTN (E.164) to URI address (Uniform Resource Identifier)can be used. In this research, we interconnect Open IMS and Asterisk server Enum server. We then analyze the server performance and PDD (Post Dial Delay...

This paper reports a study on a single server queue with bulk arrival and bulk service patterns wherein the incoming traffic depends on the state of the server which may be in operating or breakdown state. The repair of the breakdown server is performed in two phases. The operating duration of server, repair duration of both phases of repairing as well as job's inter-arrival times and service t...

In this paper, we present a novel algorithm for VANET using cloud computing. We accomplish processing, routing and traffic control in a centralized and parallel way by adding one or more server to the network. Each car or node is considered a Client, in such a manner that routing, traffic control, getting information from client and data processing and storing are performed by one or more serve...
