Integration of cellular network and wireless LAN

This study discusses the significant problems accommodated in the integration of cellular networks and WLANs to the service providers, end-users, etc. This study aims about the current complications, current challenges, substantial significance, future implementations, and the future challenges related to the integration of cellular networks and WLANs. We are performing the research to specifically identify the issues of the integration and how to eliminate these problems to produce a network that delivers higher productivity to users in terms of bandwidth, coverage area, etc. The integration of networks is now in high demand as a diverse range of mobile devices, applications requires the network to be integrated in order to utilize the service anywhere, anytime, and at a reasonable cost. The crucial component in integration is the handoff process that takes place when the user moves from one network to another without experiencing any interruption. Some issues must be considered in all the layers of the protocol stack in order to contribute a breath-taking performance to the end-users who are central to the networks. This study is carried out by referring to past written articles, documents, records, by other researches. This study identifies the problems and issues related to the protocol stack, provides the readers with the importance of integration, and the discussion about this integration of the network

Electrical withstand performance of Malaysian based palm oil under influence of HVDC stress

Overvoltage is a phenomenon where electrical waveform applied to circuit or device exceeds normal operating parameters. The sources of overvoltage are often unpredictable and can lead to permanent degradation, failure or temporary malfunction of devices and systems. Equipment running with HVDC needs to be equipped with a proper protection system and insulation strength properties better than typically being rated to the HVAC system

A parallel compact-TVD method for compressible fluid dynamics employing shared and distributed-memory paradigms

A novel multi-block compact-TVD finite difference method for the simulation of compressible flows is presented. The method combines distributed and shared-memory paradigms to take advantage of the configuration of modern supercomputers that host many cores per shared-memory node. In our approach a domain decomposition technique is applied to a compact scheme using explicit flux formulas at block interfaces. This method offers great improvement in performance over earlier parallel compact methods that rely on the parallel solution of a linear system. A test case is presented to assess the accuracy and parallel performance of the new method
