Internet of things (IoT) becomes the backbone of the advanced countries and it has a real contribute to exchange the traditional style or way of practical life, even personal life into smart style, with (IoT) technology the life become more and more easy and professional. internet of things achieves various applications coordinate with sensors and standard protocols to apply what is called machine -to- machine connection (M2M), in this paper we will talk more about the concept of (M2M), the main component of internet of things and finally the common protocols that is used in network, in addition to that this work present an IOT operation with processing system using camera for capturing image and Xilinx system generator(XSG)models for designing image processing algorithms and the result of the processing is an image with black and white for edge detection and Thresholding models and gray color image for gray enhancement model.

This study aims at extending the current understanding on the nano-scale deformation mechanisms in lath martensite. The microstructure of lath martensite is set by the prior austenite grain size and each grain is divided into packets of martensite laths. Each packet comprises blocks and even sub blocks, and these in turn are constructed from parallel laths of martensite. Lath boundaries within a block are low angle, taking up the small misorientation. Block boundaries are high angle twist boundaries. Understanding and modelling the details of the dislocation-grain boundary (GB) interactions is a key for understanding softening behavior and strengthening mechanisms of lath martensite and is of basic scientific and practical importance. In the present paper we investigate the atomic structure of several low and high-angle twist GBs and study the interaction between dislocation and GBs via Molecular Dynamics (MD) simulations. Our simulations reveal a difference in dislocation transmission across high-angle and low-angle GBs. At low-angle lath boundaries dislocation motion is hindered by dense network of intersecting screw dislocation segments. As a critical stress is reached the junctions between the dislocations forming the network unzip and a high density of dislocations is emitted into the adjacent grain. At a high-angle block boundary, it is not possible to distinguish individual interfacial dislocations. The incoming dislocation is simply absorbed into the GB plane where the line defect is not possible to be distinguished as an individual interfacial dislocation. With increasing the orientation angle the blocking strength of the GBs increases. As a critical stress is reached low density of 1/2 [111] screw segments is emitted into the adjacent grain.

Liquid metal heat transfer systems are a technically attractive option to increase the efficiency of CSP plants. Sodium as heat transfer medium is promising especially due to high heat transfer rates. In this paper, basic considerations are made to match the requirements of a small-scale loop with sodium as heat transfer medium. The setup of the test facility KArlsruhe ReceIver test FAcility (KARIFA) to heat up this loop with a 20 kW IR laser is described. The loop is planned as an integrated design using an additive manufacturing process. Different technologies like selective laser melting (SLM) are established processes to realize an integrated design and to bring together components in one part. Some variations must be implemented to adapt these processes to liquid metal loops. The high heat fluxes also demand a flow simulation to ensure an efficient and safe operation. A Reynolds-averaged Navier-Stokes (RANS) steady state simulation was performed to show the surface and duct temperatures as well as dimensionless values to analyse the characteristics of the sodium flow.

In the present paper we analyze the construction of fundamental analytic solutions (FAS) for the generalized Kulish-Sklyanin models (KSM) for vanishing (VBC) and constant boundary conditions (CBC). Using FAS one can reduce the direct and inverse scattering problems for the Lax operator to a Riemann-Hilbert problem (RHP). For VBC we find two FAS $\chi^+(x,t,\lambda) $ and $\chi^-(x,t,\lambda) $ analytic in the upper/lower $\mathbb{C}_\pm$ complex $\lambda$-plane. The RHP consists in: given the sewing function $G(x,t,\lambda)$ to constructing both $\chi^\pm(x,t,\lambda) $ in their regions of analyticity. For CBC the problem becomes more complicated, because now the RHP must be formulated on a Riemannian surface of genus 1., Comment: 17 pages, 2 Figures
