Spontaneous facial micro-expression analysis has become an active task for recognizing suppressed and involuntary facial expressions shown on the face of humans. Recently, Local Binary Pattern from Three Orthogonal Planes (LBP-TOP) has been employed for micro-expression analysis. However, LBP-TOP suffers from two critical problems, causing a decrease in the performance of micro-expression analy...

Within the last years, new techniques for network covert channels arose, such as covert channel overlay networking, protocol switching covert channels, and adaptive covert channels. These techniques have in common that they rely on covert channel-internal control protocols (so called micro protocols) placed within the hidden bits of a covert channel’s payload. An adaptable approach for the engi...

The rating curve is the relationship between the water stage and the associated discharge in a givensection of a channel. In steady flow, this relationship usually has exponential type, whereas inunsteady it flow has a looped shape. Since direct developing of actual looped rating curve by usinghydrometric methods is merely possible, steady-state rating curve is commonly used as a downstreamboun...

We present a fluorimetry-based technology for micro-RNA-21 (miR-21) sensing based on the concentration of miR-molecular beacon (MB) complexes and flushing unbound MB. This module consists microfluidic channel with shape funnel operated electrohydrodynamic actuation. report limit detection 2 pM in less than 1 min miR-21 alone, then demonstrate that levels, measured fine needle biopsy samples, fr...

This paper aims to simulate an immiscible two-phase flow in two-dimensional T-shaped, modified cross-shaped, and cross-shaped micromixers numerically. The effects of various parameters, including Capillary number, phase rate ratio, channel width on the generation droplets were studied. Also, modification T-shaped was proposed. results reveal that equidistant tiny are generated compared ordinary...

We present a laterally emitting, coupled cavity micro fluidic dye ring laser, suitable for integration into lab-on-a-chip micro systems. The micro-fluidic laser has been successfully designed, fabricated, characterized and modelled. The resonator is formed by a micro-fluidic channel bounded by two isosceles triangle mirrors. The micro-fluidic laser structure is defined using photo lithography i...

The Micro pump is an essential component in a Micro Total Analysis System (μTAS). A feasible and reliable design of the micro pump is a key for the development of the μTAS. The Valve-less Rectification Micro Pump (VRMP) has many advantages, such as: non-moving parts, independent of fluids and channels properties, reliable, and easy to fabricate. Fluid diodicity is an essential parameter of the ...

Recently, there are increasing interests in inferring mirco-expression from facial image sequences. Due to subtle facial movement of micro-expressions, feature extraction has become an important and critical issue for spontaneous facial micro-expression recognition. Recent works usually used spatiotemporal local binary pattern for micro-expression analysis. However, the commonly used spatiotemp...

A neural network based vision system for micro workpieces manufacturing is developing. The system has to recognize the shapes of the micro workpieces and to give the information for correction of the workpieces manufacturing process. The system prototype was proved off-line on the task of 3 mm screw shape recognition. The shape distortions were made with the incorrect position of the cutter in ...
