The CubeSat design process is comprised of choice of its trajectory, determination of components and main parameters of its systems, development of external and internal layouts, determination of the number of satellite-born antennas and their main characteristics. The potential of CubeSat has prompted the scientific community to rethink the existing spacecraft technologies, and think about how to make them suitable for CubeSats. In terms of specialization of engineering works during SmallSats development, was formulated concept of the design process and recognized physical relationships to find some optimal design solution about compatibility of basic parameters and characteristics. The purpose of SmallSats rational design is to create a project of a vehicle for which the value of the selected criterion is close to the maximum or minimum value. As a result, the design algorithm version was making.

In recent years the demand for the light weight material, low cost and high performance material is needed. In case of MMC‟s, aluminium matrix composite due their high strength to weight ratio, low cost and high wear resistance are widely manufactured. In this present experimental work the production of Alsi 10mg is reinforced with quartz material by stir casting method. The resulting composite produced from cast is tested for their mechanical properties without heat treatment and with heat treatment on the casting samples and compared with each other.The project aims to provide solution for optimum reinforcement percentage, and also suggest that the heat treatment on casting will increase their mechanical properties substantially.

Keywords: Hybrid Composite material, Hardness, Impact test, Stir casting process, Tensile strength.

In this paper, phenolic-resin polymerization was reviewed by placing emphasis on the influence of method of production and its operating conditions on the product yield and kinetics of phenol-formaldehyde pre-polymer synthesis. Batch and semi-batch techniques were used to synthesize novolac and resole resin pre-polymers using standardized phenol to formaldehyde mole ratios. The operating conditions for the reactions were varied in order to measure its influence on reaction performance and kinetics. The results obtained showed that yield of phenolic-resins generally increased with increasing catalyst concentration and reaction temperature. Optimum yield for novolac resin synthesized by batch process was 77.5 %; while that for novolac and resole resins synthesized by semi-batch processes.............

Keywords: Phenolic-resin pre-polymer, operating condition, kinetic parameter, synthesis technique and phenol-formaldehyde mole ratio.

Cache management has undergone various dimensions in the Computational field, by keeping the objective of computational performance for High Performance Computation(HPC). Cache Management in Multiprocessor Systems leads to a new problem called Cache Coherency Problem. This problem basically addresses the issue of maintaining consistency among Memory and Cache contents. Even in Distributed Systems, Cache Coherency Problems needs to be addressed and Directory Based Cache Coherency Model is one such solution for this Problem..........

Semantic segmentation is labelling each pixel for which an image or a class belongs to. The ability to perform pixel-wise semantic segmentation in real-time is of extract more detailed information of the image. Learning about thousands of objects from millions of images, a model with a large learning capacity is required. In this paper, a deep neural network model named ENet is discussed as efficient neural network and for tasks precisely requires low inference value. ENet is nearly 18 times faster, has 79 times less parameters, and provides better accuracy to existing models. The ENet model on OpenPOWER architecture would provide much better results with less speed throughput on the CPU / GPU.

Keywords: OpenPOWER, deeplearning, ENet, semantic segmentation.

Cadmium oxalate CdC2O4.3H2O (CdOx) and sodium cadmium oxalate [Na4Cd2 (C2O4) 4.4H2O] (NaCdOx) were grown as single crystals using single diffusion silica gel technique and the conditions influencing the size, shape and quality were optimized at ambient temperature. Single crystal XRD was carried out to analyze the crystal structure. A monoclinic system with the space group P21/n was revealed using full matrix least square technique employing the SHELXL program. The results of the structural analysis indicate that the complex formed by the Na-O and Cd-O coordination bonds explore a two-dimensional network structure which was further linked by O-H···O hydrogen bonds to give a three-dimensional structure............

Medical care data are huge with rich information and the records are increased within hours. Managing this heavy load of database with confidence and integrity is a major concern. In this study encryption and Convolution Neural Network has merged to give high security for accessing the patient data for medication. The finger print along with the face recognition of the authorized and authenticated doctors enhances the degree of security for the healthcare data. The cybersecurity awareness should be given to all the employees on a monthly basis and to train the newly joined staff. Regular backups and preserving the encrypted data are other concern to cope with ransomware attack.
