The fabrication of the micro-channel array through micro-embossing on an ultrafine-grained (UFG) LZ91 Mg-Li alloy was investigated in this paper. Micro-embossing tests indicated that the depth of the channels increase with increasing temperatures. Micro-array channels with widths ranging from 50 μm to 200 μm were performed with an applied force of 2 kN at 423 K, following by a dwell time of 60 ...

This paper proposes a novel protein micro arrayer employing 3-in-1 chip system, instantly delivering hundreds of biosamples in parallel for disease diagnosis. The 3-in-1chip system included: micro filling chip, micro stamper array and micro bio-reaction chip, applicable to high throughput disease diagnosis and drug screening. Capillary force is applied to drive liquids flowing through all the c...

The present study examines the entropy generation of graphene nanoplatelet (GnP) suspended in different basefluids, theoretically. GnP water (W), ethylene glycol (EG) and glycol- (EGW, 1:1) was examined under laminar flow state a unit length mini micro-channel 3mm 0.05mm diameter. coefficient conductivity (Ck) viscosity (C?) nanofluid were determined from experimental analysis their order magni...

Accurate liquid flow control is important in most chemical analyses. In this work, the measurement of liquid flow in microliters per minute was performed, and feedback control of the flow rate was examined. The flow sensor was arranged on a channel made in a polydimethylsiloxane (PDMS) block. The center of the channel was cooled by a miniature Peltier device, and the change in temperature balan...

In order to achieve the high-precision and high-efficiency machining of micro-channels for hard brittle materials, authors innovatively proposed a new technology called template-based electrophoretically assisted micro-ultrasonic (TBEPAMUSM). This transfers micro-channel shape punch-pin workpiece material through form micro-channel. At same time, it uses electrophoretic properties ultra-fine ab...

The development of a planar wideband directional channel model applicable to UMTS micro-cells is addressed. The model, a statistical one based on geometrical considerations, is implemented and simulated, its assessment being performed based on global parameters of channel impulse responses obtained from measurement results. Exemplifying results for the directional channel impulse response are d...

MACRO SPITBOL (1) is a compiler/ interpreter for a variant of SNOBOL4 (3), SPITBOL (4), which has been implemented on a variety of large computers. MICRO SPITBOL is an adaptation of the system for use on micro and minicomputers which compiles a language identical to MACRO SPITBOL with the exclusion of real arithmetic. The goal was to preserve the structure and machine independence of the system...

In recent times, micro aerial vehicles (MAVs) are becoming popular for several applications as rescue, surveillance, mapping, etc. Undesired motion between consecutive frames is a problem in a video recorded by MAVs. There are different approaches, applied in video post-processing, to solve this issue. However, there are only few algorithms able to be applied in real time. An additional and cri...
