In this paper, a planar antenna for Long Term Evolution (LTE) bands and Wireless Local Area Network (WLAN) is proposed. The based on coupled-fed monopole with distributed inductor direct-fed monopole. These three components form two of operations namely low operating band from 0.59 to 0.635 GHz high 1.67 2.80 GHz. satisfy the WMTS 610, UMTS 1700, GSM 1800, LTE 1900, 2100, WLAN 2400, 2600 3600 a...

Abstract— The flow past an infinite vertical isothermal plate started impulsively in its own plane in a viscous incompressible two-phase nanofluid has been considered by taking into account the viscous dissipative heat. Two nano particles Copper (Cu) and Alumina (Al2O3) are submerged in a base fluid, Water (H20). The coupled non-linear partial differential equations which govern the flow are so...

ABSTRACT The use of a thermoelectric generator (TEG) in generating useful power from solar thermal energy is demonstrated. This device represents a portable and autonomous power generation system operating from solar power, capable of powering micro/nano systems. The TEG was integrated with a micro solar thermal collector plate to enhance the thermal radiation absorption capacity of the hot sid...

In this paper, the entropy generation minimization (EGM) method is applied to an industrial heat transfer problem: the forced convective cooling of a LED-based spotlight. The design specification calls for eighteen diodes arranged on a circular copper plate of 35 mm diameter. Every diode dissipates 3 W and the maximum allowed temperature of the plate is 80 °C. The cooling relies on the forced c...

Precious Plate, Inc. is a local electroplating company that uses a variety of metals during its processes. Post-deposition, the aqueous phase used is designated for disposal, which poses problems regarding the metal content of the waste stream. First, EPA regulations mandate that metals be kept below specific levels. Even at levels capable of meeting EPA limits, the loss of metals within their ...

The Rayleigh–Taylor instability in metal is of great practical interest to a diverse range fields, and it significantly different from the traditional fluid interface instability. In this paper, set high explosives driven experiments copper plate are presented for intensively understanding perturbation growth behavior history on at specific time recorded by flash radiography. experimental resul...
