As a result, not only service receivers face an unexpected trouble but also service providers fail to get their jobs according to their skills. A generic platform providing two way communication between service provider and service receiver can eliminate the exhausting efforts of searching the suitable service provider and also ensures the intended job for the service provider. A feedback based rating system can improve the skills of any service provider and service receiver can eventually get better service.

The capsular polysaccharide of Klebsiella K40 is a heteroglycan which consists of pentasaccharide repeating units comprising one residue each of unsubstituted mannose, 4-substituted glucuronic acid, 3-substituted galactose, 2, 4-disubstituted rhamnose, and 2-substituted rhamnose. It Induces a metachromatic blue shift in the visible spectrum of the pinacyanol chloride from 600 nm to 500 nm. The metachromatic spectral changes have been studied during interaction of the dye cation with the polyanion at different polymer/dye molar ratios. A stochiometry of 11 for the polymer/dye has been found to exist in the polyanion-dye compound. The complete reversal of polymer-induced metachromasy has also been observed by the addition of ethanol and urea.

It is observed that in each 5%, 10% and 20% MM levels, Hardgrove Grindability index falls rapidly at first with increasing petrographic index and then rises but at a different rate.

Solder joint interface is characterized through X‐ray diffraction spectroscopy, scanning electron microscopy, transmission electron microscopy, scanning tunneling microscopy (STM), and nanoindentation studies. The use of Sn multilayers facilitates the formation of more homogeneously distributed intermetallic compounds (IMCs) with smaller crystallite sizes and higher dislocation densities at the joint interface. Nanoindentation test results manifest that the hardness, modulus, and resistance to plastic deformation of the joint interface for the samples prepared with Sn multilayer are 3.26 GPa, 123.3 GPa, and 1.5 × 109, respectively, much higher and improved than 0.32 GPa, 41.82 GPa, and 5.28 × 105 in turn, found for samples prepared without using Sn multilayers. STM results confirm a...

While each platform has its own uniqueness, the methodology of image recognition consists of a sequence of image processing tasks, development of a classifier algorithm, training and testing followed by deployment. This tutorial will delve into the programming aspects of image processing including thresholding, contouring and template matching. In order to provide practical hands on programming this tutorial will closely look at three real life applications of image pattern recognition namely ALPR using Tesseract OCR and will touch upon using CNN for character detection. The tutorial will explain the algorithm, implementation of pseudocode through Python using two major platforms: OpenCV and Tensorflow.

Firstly, the room temperature elastic moduli (Young's, shear and bulk), constants and Poison's ratios were simulated for the above structures and then their properties such as stress vs strain under tensile and compressive loading were simulated within the temperature range of 300K–2000K. The simulations were performed in both zigzag and armchair directions of graphene surface and differences were observed in the mechanical properties. Simulations revealed that the location of defects as well as their type influence the elastic moduli and constants at room temperature and that their tensile and compressive properties vary with temperature. For both MLGS, and SiC-graphene composites, the properties improved with increase in number of continuous graphene layers.
