In this work we investigate the effect of WiFi offloading in improving the interaction of a Mobile Network with the Smart Grid. In order to make demand match supply, so as to prevent grid instabilities and to effectively use the produced power, the smart grid can issue some requests to its users to increase or decrease their consumption; the users that can positively respond to the smart grid requests...
This paper utilizes concepts and tools of switching algebra to describe an algorithm for computing all candidate keys of a relational database. Our algorithm starts with a superkey comprising all attributes, and then uses logical inference to reduce it to the set of candidate keys. The essential step in this inference is the construction of the complete sum of a pertinent switching function. Some...
Wireless power transfer (WPT) consists of three major parts namely transmitter, medium and receiver. In WPT system, input power is fed to the source where it transmits and propagates via coils and delivered to the load side. For an efficient operation of the WPT system, it is important to have a good power efficiency mechanism from the input to the transmitter coil. In this paper, a simulated design...
[Background] Software Engineering (SE) is predominantly a team effort that needs close cooperation among several people who may be geographically distributed. It has been recognized that appropriate tool support is a prerequisite to improve cooperation within SE teams. In an effort to contribute to this line of research, we have designed and developed an infrastructure, called ABC4GSD, based on the...
This paper investigates the downlink resource allocation problem in Orthogonal Frequency Division Multiple Access (OFDMA) Heterogeneous Networks (HetNets) consisting of macrocells and small cells sharing the same frequency band. The focus of this study is to devise an energy efficient scheme that allows shared spectrum access to small cells, while ensuring a certain level of quality of service for...
The voting system is set of rules which define how the desire of people may be express and how results may be achieved from it. For this purpose an electronic voting machine EVM is introduced in this paper which replaced conventional methods of voting i-e manual voting. Proposed machine in this paper is faster, efficient, and reliable and error free as compared to manual voting system which is slower,...
Several design challenges of a low pass continuous time delta sigma modulator (LP DSM), to be used in switched mode transmitter architecture, have been identified. MATLAB simulations and modulation schemes for LP DSM have been presented. Various analog issues, mainly concerned with loop filter design, are discussed. Finally a highly efficient switched mode transmitter architecture using delta-sigma...
In this paper, we propose a novel energy-aware adaptive sectorisation strategy, where the base stations are able to adapt themselves to the temporal traffic variation by switching off some sectors and changing the beam-width of the remaining sectors. An event based user traffic model is established according to Markov-Modulated Poisson Process (MMPP). Adaptation is performed while taking into account...
An improved Dynamic, Partial and self reconfigurable interconnection network (Hybrid-2 Network) is presented for Dynamically Reprogrammable Resource Array (DRRA), which is a Coarse Grain Reconfiguration Architecture (CGRA). To justify the design decision, Hybrid-2 network implementation is compared against the possible implementations using Multiplexer, NoC, Crossbar and already published Hybrid-1...
