Energy efficiency is becoming more important in database design, i. e., the work delivered by a database server should be accomplished by minimal energy consumption. So far, a substantial number of research papers examined and optimized the energy consumption of database servers or single components. In this way, our first efforts were exclusively focused on the use of flash memory or SSDs in a...

The utilization of photovoltaic energy becomes an important source of electrical energy with the advancement in power electronic technology. The dc-dc converters is one of inevitable part of renewable energy system, for connecting the PV panel to the grid or AC load through an inverter. MPPT (Maximum Power Point Tracking) maximizes the power production of the PV panel. The advantages of high st...

Lithium metal battery promises an attractively high energy density. A Li-utilization rate of Li anode is the prerequisite for density and avoiding a huge waste resource. However, dendritic deposition gives rise to “dead Li” parasitic interfacial reactions, resulting in low utilization rate. Herein, regulated spherical by designing MXene host with egg-box structure, suitable curvature, continuou...

In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...

The energy utilization ratio (ER) quantifies the of a Switched Reluctance Motor (SRM). Calculation ER an SRM can be different from other motors as it has highly non-linear operating characteristics and uses asymmetric bridge converter. In this paper, concept for SRMs been explained first then computation methodology is presented based on co-energy stored in magnetic system. are evaluated ANSYS ...
