In this study, effects of extended jet holes to heat transfer and flow characteristics of jet impingement cooling were numerically investigated. Cross-flow in the impinging jet cooling adversely affects the heat transfer ...

Photovoltaic (PV) systems produce a significant amount of electrical energy used around the world. The performance of a PV array is affected by temperature, solar insolation, shading and array configuration. Obtainable ...

Electromagnetic waves caused from base stations, which are rapidly increasing due to the opportunities provided by modern technology, create an undesired effective electromagnetic pollution in the environment. Mobile phones, ...

It has become vitally important to control the use of the energy resources in our world of severe energy depletion. Elevators (and the escalators) constitute an important part in total energy consumption of modern high ...

Failures in digital devices can be caused by ESD-pulses coupled directly or indirectly to input pins. Weak pulses will not destroy a device but can be interpreted as logical signals (ESD soft failure). In this paper, a ...

Hydrogen has many excellent combustion properties for improving combustion and emissions performance of spark ignition (SI) engines. This article presents a comparative energy and exergy analyses of a hydrogen-methane ...

This paper is devoted to the study and analysis of a two-machine infinite-bus (TMIB) power system by applying Lyapunov (energy) function based on the variable gradient method. Firstly, the TMIB power system's energy function ...

Energy-efficiency (EE) is a critical metric in many types of wireless networks and is getting increasingly important for new technologies. In this paper, the authors propose an energy-efficient decode-and-forward relaying ...
