In this study, we present an application of neural network and image processing techniques for detecting the defects of an internal micro-spray nozzle. The defect regions were segmented by Canny edge detection, a randomized algorithm for detecting circles and a circle inspection (CI) algorithm. The gray level co-occurrence matrix (GLCM) was further used to evaluate the texture features of the s...

Polarimetric imaging has proved its value in medical diagnostics, bionics, remote sensing, astronomy, and in many other wide fields. Pixel-level solid monolithically integrated polarimetric imaging photo-detectors are the trend for infrared polarimetric imaging devices. For better polarimetric imaging performance the high polarization discriminating detectors are very much critical. Here we dem...

Abstract– The design and fabrication of integrated microlenses for CMOS single-photon avalanche diodes (SPADs) is presented in this paper. The micro-lens exploits the avalanche propagation phenomenon occurring in abrupt single-sided junctions and is achieved by carful design of the SPAD in a standard CMOS process. In contrast to an optical micro-lens, the proposed technique is more robust to m...

Micro-Tube Plasmas (?TP) have been gaining attention for applications ranging from medicine to material science and analytical chemistry due their small size, low cost of operation flexibility. In the present work a specific ?TP, known as Flexible Micro Tube Plasma (F?TP) is investigated experimentally and, first time, numerically well. The creation, propagation mechanisms properties ionization...

It is considered that the process of fatigue fracture could be arranged the three classes, i.e., crack initiation, crack propagation and fracture. Of these the second process is important from the following point of view. (1) As has so far been reported in many publications, the importance of crack propagation process in total fatigue life increases in proportion to the increase in the stress c...

background: whispering gallery modes (wgm) biosensors are ultrasensitive systems that can measure amount of adsorbed layer onto the micro-cavity surface. they have many applications including protein, peptide growth, dna and bacteria detection, molecular properties measurements and specific interaction and drug table recognitions due to their high sensitivity, compact size and label free sensin...
