The interactions among the multi-carrier energy systems provide opportunity to achieve affordable and clean by using resources in a more efficient way. In this paper, transactive (TE) framework for optimal management of multiple hubs (EHs) is proposed. Each EH system performing day-ahead schedule its electrical, thermal, cooling demand profiles manages internal reduce total expenses emission le...

Multi-energy systems (MES) are considered various energy carriers and energy players in an integrated energy model. Vast amount of decision making data is gathered in these systems that cannot be processed by conventional methods. Cloud-based computing is an opportunity to develop these kinds of integrated and efficient approaches. Developing mathematical models that can be compatible with clou...

an efficient cluster head selection algorithm in wireless sensor networks is proposed in this paper. the implementation of the proposed algorithm can improve energy which allows the structured representation of a network topology. according to the residual energy, number of the neighbors, and the centrality of each node, the algorithm uses fuzzy inference systems to select cluster head. the alg...

This paper presents a review on energy efficient WiseMAC Protocol for wireless sensor networks. Among various MAC layer protocol WiseMAC is a known as one of the most energy efficient protocol. Non-persistent carrier sense multiple access (np-CSMA) and the preamble sampling technique are the main techniques used in basic WiseMAC protocol, they are used to reduce the consumption of power when en...

In order to reduce both the weight of vehicles and the damage of occupants in a crash event simultaneously, it is necessary to perform a multi-objective optimization of the automotive energy absorbing components. In this paper, axial impact crushing behavior of the aluminum foam-filled thin-walled tubes are studied by the finite element method using commercial software ABAQUS. Comparison of the...

We present an energy analysis technique applicable to medium access control (MAC) and multihop communications. Furthermore, the technique’s application gives insight on using multihop forwarding instead of single-hop communications. Using the technique, we perform an energy analysis of carrier-sense-multiple-access (CSMA-) based MAC protocols with sleeping schemes. Power constraints set by batt...

In order to achieve stringent greenhouse gas emission reductions, a transition of our entire energy system from fossil renewable resources needs be designed. Such an brings two main challenges: most renewables generate variable electric energy, yet demand is currently not (carrier mismatch) and does always manifest at the same time as supply (temporal mismatch). Integrating multiple infrastruct...
