With the development of the aerospace and automotive industries, high heat exchange efficiency is a challenge facing the development of various industries. Pure copper has excellent mechanical and physical properties, especially high thermal conductivity and electrical conductivity. These excellent properties make pure copper the material of choice for the manufacture of heat exchangers and other electrical components. However, the traditional processing method is difficult to achieve the production of pure copper complex parts, so the production of pure copper parts through additive manufacturing has become a problem that must be overcome in industrial development. In this article, we not only reviewed the current status of research on the structural design and preparation of complex pure copper parts by researchers using selective laser melting (SLM), selective electron beam melting (SEBM) and binder jetting (BJ) in recent years, but also reviewed the forming, physical properties and mechanical aspects of pure copper parts prepared by different additive manufacturing methods. Finally, the development trend of additive manufacturing of pure copper parts is also prospected.

Performance Computing

Current high-end graphics processing units (abbreviate to GPUs), such as NVIDIA Tesla, Fermi, Kepler series cards which contain up to thousand cores per-chip, are widely used in the high performance computing fields. These GPU cards (called desktop GPUs) should be installed in personal computers/servers with desktop CPUs; moreover, the cost and power consumption of constructing a high performance computing platform with these desktop CPUs and GPUs are high. NVIDIA releases Tegra K1, called Jetson TK1, which contains 4 ARM Cortex-A15 CPUs and 192 CUDA cores (Kepler GPU) and is an embedded board with low cost, low power consumption and high applicability advantages for embedded applications. NVIDIA Jetson TK1 becomes a new research direction. Hence, in this paper, a bioinformatics platform was constructed based on NVIDIA Jetson TK1. ClustalWtk and MCCtk tools for sequence alignment and compound comparison were designed on this platform, respectively. Moreover, the web and mobile services for these two tools with user friendly interfaces also were provided. The experimental results showed that the cost-performance ratio by NVIDIA Jetson TK1 is higher than that by Intel XEON E5-2650 CPU and NVIDIA Tesla K20m GPU card.

The Impact

This article discusses the issues of autonomous operation of electrical agricultural equipment based on the transmission of electricity over a distance. The main point of this article is that tractors that work in the field are driven by electric motors, with the need to use expensive batteries. The issues of the impact and safety of this technology on the environment and humans are considered. The main problem of the creation, maintenance and operation of transport equipment, including agricultural equipment, is the high cost of maintenance and fuel, which are constantly increasing. In addition, the environmental problem, which has become so acute in recent years, global warming, the fuel crisis and the need to transfer all transport equipment to electric traction, make us look for new ways to solve the problem of environmental pollution and save resources, especially non-renewable energy sources. The use of electrical energy for traction of agricultural machinery that work in the fields or in other industries has been used for a long time, and in the early stages of the development of transport, it was electric transport that occupied the main part, before the invention of the internal combustion engine. Including at the Kharkov Tractor Plant there were developments (and still are), a prototype of the use of electric motors as the main unit for movement. Based on the above, it is obvious that electric traction for transport is obviously environmentally friendly and safe, although there are a number of limitations in this matter as well, but the unresolved problems of the limited use of the storage battery force us to look for new sources of energy. This article proposes to consider the possibility of using electric traction for agricultural machinery with the supply of operating tractors in the fields with the help of a directed electromagnetic wave with its transformation into electrical energy, which will be supplied to the electric motor.
