The ever-increasing operational cost of geographically distributed datacenters has become a critical issue for cloud service providers. In order to cut the electricity cost of geographically distributed datacenters, several workload management schemes have been proposed, such as Electricity price-aware InteR-datacenter load balancing (EIR), which reduces the electricity cost of active servers b...

Electric vehicles (EVs) are becoming increasingly popular due to their low emissions, energy efficiency, and reduced reliance on fossil fuels. One of the most critical components in an EV is storage management system, which requires compactness, lightweight, high superior build quality. Active cell equalization circuits such as those used battery systems (BMS) have been developed balance voltag...

assembly line production is one of the widely used basic principles in production system. the problem of assembly line balancing deals with the distribution of activities among the workstations so that there will be maximum utilization of human resources and facilities without disturbing the work sequence. research works reported in the literature mainly deals with minimization of idle time i.e...

We examine the constraints imposed by the requirement of successful nucleosynthesis on models with one large extra hidden space dimension and a single bulk neutrino residing in this dimension. We first use naive out of equilibrium conditions to constrain the size of the extra dimensions and the mixing between the active and the bulk neutrino. We then use the solution of the Boltzman kinetic equ...

Operating district heating systems with low supply and return temperatures improves heat production distribution efficiency, permitting greater integration of renewable sources. Low-temperature is viable without compromising comfort, but faults in end-users’ constrain temperature reductions. Such include malfunctioning valves, improper hydronic balancing, excessive setpoints. Occupants lack the...

Active cell balancing is a more energy-efficient way of cells in series comparing to passive balancing. To further improve the performance an active system, optimal control approach can be applied optimise system indexes. This paper proposes controller for bidirectional clamp forward converter with synchronous rectifier (ACFC-SR) based cell-to-external-storage concurrently speed and energy effi...

In active anycast where accesses from the clients are distributed among the servers by an active router, the information used for selecting the adequate server from the viewpoint of improvement of response time for clients is important. Response time perceived by clients consists of processing delay at the server and network delay. To realize good selection of servers, both of server processing...
