The demand-side DC electricity-using equipment and newly integrated renewables are driving the transformation of power distribution utilization mode. building system based on technology is emerging as a promising option. In low-voltage (LVDCBDUS), global energy optimization management operational control arrangement key components. To obtain exemplary achievements those, two different (DC BEMS)...

In communication systems transmitting data through unknown fading channels, traditional detection techniques are based on channel estimation (e.g., by using pilot signals), and then treating the estimates as perfect in a minimum distance detector. In this thesis, we derive and investigate an optimal detector that does not estimate the channel explicitly but jointly processes the received pilot ...

iran’s culture is changing, and by these changes preference of fit body usually thin body is growing up among women. paying too much attention to fitness is the result of a consumer society, and to reach fitness and to have acceptable body size, women try different ways such as body building, aerobic, etc. so the current study aims to explore the social factors related with women’s tendency tow...

In this paper, we propose an algorithm for channel estimation, acquisition and tracking, for orthogonal frequency division multiplexing (OFDM) systems. The proposed algorithm is suitable for vehicular communications that encounter very high mobility. A preamble sequence is used to derive an initial estimate of the channel using least squares (LS). The temporal variation of the channel within on...

Building Energy Management Systems consist of hardware and software components. The hardware set-up of BEMS is typically made up of a set of computers in charge of building control and sensoractuator networks. The software side of BEMS is usually made up of a number of functional layers that implement standard management functionalities. This paper will present an application of Model based Pre...

Recent works in the boundary element method (BEM) community have been devoted to derivation of fast techniques perform matrix-vector product needed iterative solver. Fast BEMs are now very mature. However, it has shown that number iterations can significantly hinder overall efficiency BEMs. The robust preconditioners is inevitable increase size problems be considered. Analytical offer a interes...

Electronic media and new technology have changed the way we communicate and collect information, and this is the case especially if we look at the evolution of the Internet. The phenomenon of new technology is not unexpected and a few decades ago Marshall McLuhan was mentioning the importance the electronic media, and also the global village, would have for the individual and for the structures...

Energy consumption in buildings represents approximately one-third of total energy produced globally. Towards efforts to reduce energy consumption of buildings while also improving its operational efficiency, building controls based on the Multi-Agent Systems (MAS) paradigm have been proposed and developed for use in building operations due to its key features such as learning and adaptation. T...
