We have recently developed some simple continuum models of static granular media which display "fragile" behavior: They predict that the medium is unable to support certain types of infinitesimal load (which we call "incompatible" loads) without plastic rearrangement. We argue that a fragile description may be appropriate when the mechanical integrity of the medium arises adaptively, in respons...

An improved flexible solar-aided power generation system (SAPG) for enhancing both selective catalytic reduction (SCR) de-NOx efficiency and coal-based energy efficiency of coal-fired power plants is proposed. In the proposed concept, the solar energy injection point is changed for different power plant loads, bringing about different benefits for coal-fired power generation. For partial/low lo...

Cloud computing is an emerging field of computer science, where heterogeneous services such as applications, servers and storage are delivered to an individual or organization's computer and devices through the Internet. In the proposed research work, a load balancing algorithm is designed, to provide proper utilization of all resources while processing the requests received from the users. We ...

-This paper Discuss about the problem occurring in the medium voltage distribution network such problems reactive power, harmonics and unbalanced load current compensation of Medium voltage Distribution systems. It proposes a simple and inexpensive solution to enhance power quality when a particular connection to the high voltage transmission network. It presents the design of a active power fi...

̈C This paper presents a concept of transmission of electrical energy from a power source to an electrical load without physical conducting medium. It is based on the well known principle of resonant inductive coupling and, in particular, resonant evanescent coupling [1] .This well known physics leads trivially to the result of energy efficient midrange wireless energy-exchange. We establish tha...

This paper analyzes in depth the asynchronous part of the MetaRing MAC protocol by considering a network configuration (hereafter scenario) in which the slot reuse capability is used to the minimum extent possible. The MetaRing MAC protocol behavior is first analyzed in asymptotic conditions (i.e., when each station is trying to seize all the medium capacity), then in underload conditions (i.e....

In this paper we study the impact of the medium access control (MAC) layer and the routing layer on the performance of a multi-hop wireless network. At the medium access control layer, we argue that the notion of per-node fairness employed by the IEEE 802.11 standard is not suitable for a multi-hop wireless network where flows traverse multiple hops. We propose a new MAC protocol that supports ...

We present a new topology for high-speed ring networks: the spiral ring. We also describe a mac{level protocol, called Distributed Spiral Multiple Access (dsma), suitable for the spiral ring topology. The dsma protocol is based on token passing and gives a fair and eecient network behaviour regardless of the transmission rate and network size. Under light load, the medium access delay approache...

Abstract – This paper presents and analyses a new near–optimum medium access control (MAC) protocol. The proposed access scheme is suitable for a CDMA mobile communication environment and minimises the total number of spreading codes needed to achieve a certain throughput. It also has a delay performance approaching that of an ideal optimum M/M/K system, where K is the number of spreading codes...
