Abstract: Due to its high viscosity, it is very difficult to develop heavy oil cost-effectively. Currently, CO2 huff and puff method is a better choice to develop heavy oil reservoir. The key to this method is to choose the suitable candidate target wells. However, it is now very difficult to judge the suitability of the horizontal target wells’ heavy oil reservoirs’ CO2 huff and puff. In according to such issue, this paper, based on the entropy weight method of fuzzy comprehensive evaluation, and used the established horizontal wells’ index in heavy oil reservoir CO2 huff and puff, evaluates the suitability of candidate wells comprehensively. Moreover, this paper presents a set of indicator system that suits the choice of horizontal wells with regard to its heavy oil reservoir CO2 huff and puff, and proposes a specific method and procedures to evaluate an individual candidate well. This project uses such method to calculate 19 horizontal wells in area G, and the evaluation results are consistent with the actual situations. Therefore, it proves that such proposed evaluation method and evaluation index system are feasible to a certain extent.

Abstract: By used the assumed mode method to simulate the iced transmission line galloping,with three generalized coordinates to represent the iced transmission line galloping. In order to avoid the complicated calculation of vector,used the Lagrange equation to build the nonlinear equations of iced transmission line from the perspective of energy,used the Runge-Kutta numerical calculation to solve the equations of motion and get the iced transmission line’s across-wind,along-wind and the torsional response. Based on Lyapunov stability theory to deduce the critical wind speed of the iced transmission line galloping. And had used a test iced transmission line to verify the feasibility of the numerical solution and the critical wind speed.

Abstract: One array code scheme is proposed for double erasures correcting. The scheme made use of horizontal and oblique data placements to accommodate parity strips. The scheme can reduce the occurrences of bottlenecks in part due to the oblique placement. The encoding and decoding algorithms can be used in distributed storage. It has been proved that the code with the encoding scheme is MDS. It has also been indicated that the decoding scheme is effective for array code (p-1)×(p+1) when p is and only is a prime number. Moreover, two placements stripes are not associated with each other, which made it much easier for decoding to tolerate double erasures.

Abstract: With the development and advancement of technology, innovation and support the development of new product design is inseparable from the concept and methods of industrial design, industrial design not only has become an important means of market competition, but also become the country with the economy powerful weapon development. This paper discusses the development of industrial design disciplines to analyze the computer-aided industrial design (CAID) the basic meaning and value, and through man-machine engineering design and creative thinking intelligent technology applications in the study of CAID, will make the final interpretation of the industrial design CAID grand blueprint towards a more diversified and high-level areas continue forward.

Abstract: Corrugated board is a kind of important material for packaging liner. According to packages of ceramic wine suits and single ceramic bowl, we designed folding liners and multi-layer liners using corrugated boards. Experiments are taken out to compare mechanical properties of different liner structures. Best corrugated liner forms are summarized considering amount of corrugated boards, mechanical properties, convenience in manufacturing, and convenience in using.

Abstract: The purpose of this study is to apply a new design method, which integrates both optimum strength and product design. Here, the collaboration of design and strength by using composite materials is administered. Many products, which are made from high strength composite materials, require new product design technology. Existing product developments tend to separate product design from product planning. The process begins from planning the shape of the product, then calculating the strength, and lastly designing the product. In our new design method, we create from an engineering point of view. By using a design method of high-strength materials, we designed a new ZIGZAG CHAIR made of carbon fiber reinforced plastic of excellent strength and light-weight.

Abstract: The issue of traffic jam in Indonesia’s big cities alike in Jakarta, Bandung, Medan, Makassar and Surabaya encourage the government, civilization and transportation expert initiate to consider a elucidation to solve the problematic above. The growing of the vehicle number which is extended faster than the establishment of road affect the bottleneck could not to be avoided. Furthermore the pollution problem which is produced by car exhaust where the number of them always increase each year make the air pollution in the settlement becomes crucial. Additionally within the backwards issue of the reducing of the using of fuel because of the source of them become limited. People have to consider sincerely before buying the vehicle due to the high operational cost. One of the solutions of the problem is the using of human power vehicle asThe study try to respond the need of people to enjoy the using of tandem bike but also still could be used as the single bike more over the storage problem is disappear. The research team agrees to give the name of this ‘novel bike’ as Trandem: the existing tandem bike which is transform to the dual function.

Abstract: In this paper, domestic and foreign progress and some of the results obtained in the field of conductive textile research are introduced. An intelligent quilt concept is conceived. The intelligent quilt is made from natural plant improved by genetic technology. It has certain “conductivity”, which is not necessarily the true current conduction, but may be the conduction of some weak “unique signal” sent out by some specially bred textile fibers organization. The research results of flexible sensor are applied to trace gas detection in the intelligent quilt. Also, new energy supply strategy with combination of. Bioenergy technologies and other energy are employed. The proposed intelligent quilt may be applied to the monitoring biochemical and autonomic parameters of the human body and provide helpful suggestions on people’s health status.
