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 […]
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 […]
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 […]
Inductors are one of the key components and are widely used in modern RFIC and MMIC systems. With the increasing trend of working frequencies, high performance inductors are greatly demanded and indispensable in current and future communication systems. However, inductors generally take large chip area and play a limiting role in further reducing size and […]
In this paper, we investigate the end-to-end performance of dual-hop proactive decode-and-forward relaying networks with Nth best relay selection in the presence of two practical deleterious effects: i) hardware impairment and ii) co-channel interference. In particular, we derive new exact and asymptotic closed-form expressions for the outage probability and average channel capacity of Nth best partial and […]
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. […]
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 […]
In this study, a hybrid, energy efficient MAC (Medium Access Control) protocol has been developed for usage in dense WSN (Wireless Sensor Network) applications. In the designed hybrid MAC, favorable aspects of both CSMA (Carrier Sense Multiple Access) and TDMA (Time Division Multiple Access) techniques are considered. Consequently, a MAC protocol which is more energy […]
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 […]
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 […]
