Evaporation in the micro-gap heat sink has a very high transfer coefficient. As result, it is significant for flux management. Heat rate can be enhanced further by including internal micro-fins. However, pressure drop penalty due to small gap height and fin surfaces major concern. Wall shear stress development responsible drop. This paper investigates effects of operating conditions, e.g., wall...

We present a straightforward microfluidics system to achieve step-by-step reaction sequences in a diffusion-controlled manner in quasi two-dimensional micro-confinements. We demonstrate the hierarchical self-organization of actin (actin monomers-entangled networks of filaments-networks of bundles) in a reversible fashion by tuning the [Formula: see text] ion concentration in the system. We show...

Micro-fluxgate sensor with symmetrical core on both sides of the planar rectangular excitation and pick-up coils has substantially improved parameters compared to its single-core predecessor. Almost closed magnetic path for the excitation field allows much deeper saturation of the sensor core, which reduces the perming effect, hysteresis and noise. Perming of max. 5 μT for 6 mT field shock, 28 ...

The objective of this research is to define a methodology for designing presents the simulation and design analysis of fully integrated receiver system for millimeter and microwave applications. A beauty thought of new design of CMOS LNA, filter and micro strip antenna are largely improves the system integration, reduced chip area and save the cost. In this paper, a three different architecture...

In relation to the time-scale of chemical kinetics, diffusive transport in micro-devices is faster than in conventional mixers. To exploit the resulting potential for chemical process engineering, size effects evident in the transport processes have to be understood. For this purpose, the scaling behaviour concerning the transport of mass, momentum and heat are considered. Just as much, the mix...

Ten Vicon MX T40 (4 megapixel) motion capture cameras available in the Micro-Aerial Vehicle and Sensor Networks (MAVSeN) Laboratory at Louisiana Tech University act as the source of data. The MAVSeN lab conducts research and development in small-scale vehicle design, cooperative intelligent sensing, and control algorithms for unmanned air and ground vehicles (see Figure 1). As the figure partia...

This paper proposes a micro-strip patch antenna operate on the dual frequency bands. The proposed antenna design consists of U slotted patch with direct coaxial probe feed technique. The U slotted patch offers a low profile, high gain, broad band and compact antenna. The proposed designs are based on patch loaded with U slots in the form of cut from the sides and center of the rectangular and c...

A method of optimal material design is applied to the problem of controlling the distribution of the electric field within a material heated by microwaves in closed cavities. Analytical and computational procedures are presented for a layer in a single-mode rectangular waveguide applicator. These determine the optimal placing and micro-geometry of composite controlling materials. The particular...

Monoand bi-disperse rectangular cuboidal granules are assembled from colloid-hydrogel suspensions via stop-flow lithography and fully submerged in hexadecane. Their packing density and structural evolution are studied as a function of agitation time using micro-computed X-ray tomography. When subjected to periodic agitation, the granule packing density increases logarithmically in time; concomi...

Micro Particle Image Velocimetry (μPIV) is a non-invasive flow field measurement technique, which is becoming the method of choice for the investigation of micro-flows. Measurements of flows which occur within the human body represent one of the most important applications of μPIV. A three-component two-dimensional scanning micro-Particle Image Velocimetry (μPIV) technique is presented in this ...
