Transient thermal analysis of the conical rotor motor using LPTN and Finite Volume Method

For this investigation, the conical rotor motor of total enclosed fan cooling (TEFC) with complexity geometry is taken as a typical example . The air flow between the fins caused by the centrifugal fan embedded at the ending bearing is uncertain, thus the 3D finite volume method (FVM) model is build to estimate the flow […]

PARR: Pin access planning and regular routing for self-aligned double patterning

Pin access has become one of the most difficult challenges for detailed routing in 14nm technology node and beyond, where double patterning lithography has to be used for manufacturing lower metal layers with tight pitches. Self-aligned double patterning (SADP) provides better control on the line edge roughness and overlay but it has very restrictive design […]

Overhearing Protocol Design Exploiting Inter-Cell Interference in Cooperative GreenNetworks

The conventional two-way relaying (TWR) protocol requires that the transmitter (receiver) in one direction must be the receiver (transmitter) in the other direction, an limitation precluding the application of the TWR for sophisticated realworld wireless networks. In this paper, we study a more general multi-cell system consisting of a downlink (DL) traffic in one cell and […]

Personalized web search engine using dynamic user profile and clustering techniques

Internet is large interconnection of small networks that is commonly known as World Wide Web. The amount of informations available on internet in digital form are very huge and growing at exponential rate following Moore’s law. So, it’s makes difficult to find exact search result according to user preferences. In this paper, we proposed a method for […]

Security–A Perpetual War: Lessons from Nature

For ages, people have sought inspiration in nature. Biomimicry has propelled inventions from Velcro tape to “cat’s eyes” retroreflective road markers. At the same time, scientists have been developing biologically inspired techniques, including genetic algorithms and neural and sensor networks. Although a first glance shows no direct connection between the Internet’s offensive and defensive techniques and […]

Heterogeneity-Aware Codes With Uncoded Repair for Distributed Storage Systems

In practical large-scale distributed storage systems, node failures are unavoidable. It is therefore desirable to quickly recreate the failed nodes in order to maintain the system integrity. In this letter, we consider a family of erasure codes that provide uncoded repair, where the failed node is regenerated by transfer of data without extra arithmetic operations. […]

Platform for Multiagent Application Development Incorporating Accurate Communications Modeling

Multiagent systems are widely recognized as a method of choice for realization of distributed time-critical applications for the smart grid. However, no general solutions have been proposed for the difficult task of system development and validation, ready for deployment, which would fully account for the underlying communication network performance. We propose a novel platform designed […]

Multi-Focus Image Fusion Based on Spatial Frequency in Discrete Cosine Transform Domain

Multi-focus image fusion in wireless visual sensor networks (WVSN) is a process of fusing two or more images to obtain a new one which contains a more accurate description of the scene than any of the individual source images. In this letter, we propose an efficient algorithm to fuse multi-focus images or videos using discrete cosine transform […]

Optimum Wirelessly Powered Relaying

This letter maximizes the achievable throughput of a relay-assisted wirelessly powered communications system, where an energy constrained source, assisted by an energy constrained relay and both powered by a dedicated power beacon (PB), communicates with a destination. Considering the time splitting approach, the source and relay first harvest energy from the PB, which is equipped […]

Hybrid WLAN Markov Chain to Handle TCP and UDP Traffic

In the Modern Era of computing, The Wireless communication has gained popularity with the passage of time due to unique features, e.g. Flexibility, cost effective and easy to configure as compare to traditional wired networks. Since 1990swireless networks become the backbone of every network and there are lots of concerns in wireless communication, which are […]
