JPL has developed a small (<5 kg) spacecraft capable of visual inspection of a host vehicle with support from NASA’s Exploration Systems Mission Directorate (ESMD). The Micro-Inspector is designed to have a minimal impact on the host with respect to mass, size, cost, interface, and integration. On orbit, the host provides the separation signal to the Micro-Inspector, ejecting it to autonomously...

In recent years, there has been a desire to scale down linear quadrupoles. The key advantages of this miniaturization are the portability it enables and the reduction of pump-power needed due to the relaxation on operational pressure. Various attempts at making MEMS-based linear quadrupoles have met with varying degrees of success [1]-[3]. Producing these devices involved some combination of pr...

In this work, the fluid flow and mass transfer due to the presence of an electric field in a rectangular channel is examined. We consider a mixture of water or another neutral solvent and a salt compound, such as sodium chloride, for which the ionic species are entirely dissociated. Results are produced for the case in which the channel height is much greater than the electric double layer (EDL...

Micro-light emitting diode (micro-LED) is an emerging display technology with excellent performance of high contrast, low power consumption, long lifetime, and fast response time compared the current (e.g., liquid crystal organic LED (OLED)). With technological advantages, micro-LED holds promise to be widely applied in augmented reality (AR), flexible screens, etc. thus regarded as next genera...

We demonstrate a fabrication procedure for the direct integration of micro-ball lenses on planar integrated optical channel waveguide chips with the aim to reduce the divergence of light that arises from the waveguide in both horizontal and vertical directions. Fabrication of the lenses is based on photoresist reflow which is a procedure that allows for the use of photolithography for careful a...

abstract:the general perception of islamic finance is that it prohibits the practice of paying and receiving interest, but islamicfinance is much broader than interest rate prohibition. islamic financial services can be viewed as a set of financialservices which are diversified based on the needs of society.since in the iranian economy most of the enterprises are micro and/or small, micro finan...

a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...

--MEMS based mass sensors are being designed to identify the small amounts of materials especially for monitoring the food supply. The Fabrication of MEMS includes deposition of material layers, pattering by photolithography and etching to produce the required shapes, consequently leading to time taking and expensive method. In order to reduce the working time of sensor to market a Finite eleme...
