sensor networks generally consist of a very great number of sensor nodes which will be spread into a vast environment and aggregate data out of it. the sensor nodes are afflicted with some limitations as follows memory, reception, communication as well as calculation capability, and battery power. the transmission of a great amount of extra data increases data transmission and proportionally in...

Nuclear fusion is one of the most promising energy sources to satisfy our future needs. However, several open challenges are yet be solved for realisation electricity. Among crucial issues, it key develop innovative solutions increase lifetime components inside a reactor.

Fundamental tradeoffs in green cellular networks with coexistence of machine-oriented and human-oriented traffics are investigated. First, we present a queuing system to model the uplink transmission of a green base station which serves two types of distinct traffics with strict requirements on delay and battery lifetime. Then, the energy-lifetime and energydelay tradeoffs are introduced, and c...

background: the earlier atomic bomb explosion in hiroshima and nagasaki, and three worth mentioning nuclear accidents - detonation at fukushima daiichi nuclear plant, chernobyl nuclear fallout and an accident at three mile island nuclear power plant have made us more worried about the secure exploitation of nuclear energy. the central focus of this paper is to review radiation-mediated health e...

The energy dependence of the electron lifetime in graphite was measured using femtosecond timeresolved photoemission spectroscopy. The lifetime was found to be inversely proportional to the excitation energy above the Fermi level, i.e., sE 2 EFd, in sharp contrast to that of metals, whose lifetime is found to be proportional to sE 2 EFd. The results are in agreement with the prediction of the l...

In this letter, we propose an energy-aware source routing protocol for maximizing the network lifetime in mobile ad hoc networks. We define a new routing cost by considering both transmit and receive power consumption and remaining battery level in each node simultaneously and present an efficient route discovery procedure to investigate the proposed routing cost. Intensive simulation verifies ...

Today, information networks play an important role in supply chain management. Therefore, in this article, clustering-based routing protocols, which are one of the most important ways to reduce energy consumption in wireless sensor networks, are used to optimize the supply chain informational cloud network. Accordingly, first, a clustering protocol is presented using self-organizing map neu...
