Published: February 2014

To improve the pertinence and accuracy of grating image barcode detection, a method based on Hough transform and morphological operation about grating image full-barcode correction and extraction is proposed. The basic principles of Canny edge detection, Hough transform and morphological operation are introduced. Non full-barcode can be eliminated after Canny detection and morphological operation. The level correction can be finished by using Hough transform to detect the full-barcode edge lines and get the correction angle. The full-barcode extraction can be achieved after the dilation of correction grating image and the reduction of free defects. The experimental results show that not only the non full-barcodes and free defects can be better filtered, but also we can accurately accomplish the correction and extraction of the full-barcodes.

The rock soil thermal conductivity is the most important design parameter for the ground source heat pump system. Based on the equation applied for the heat transfer between the geothermal heat exchanger and its surrounding rock soil, a quasi-three dimensional heat conduction model showing the heat transfer inside the borehole of the U-tube was established to determine the thermal conductivity of the deep-layer rock soil. The results obtained show that the average thermal conductivity got through calculation and actual determination in a tube-embedding region of the ground source heat pump engineering were 1.895 and 1.955W/(m·°C), respectively. The soil layer, which has a great thermal conductivity and a strong integrated heat transfer capability, is suitable for the use of the ground source heat pump system with the tubes embedded underground. The soil layer, with a body temperature of 19 °C and a higher initial temperature, is suitable for the heat extraction from underground in winter. The deviation between the calculation and the determination of the average thermal conductivity in the abovementioned region was 0.06, which could meet the required precision, indicating that the results from the calculation could be used for design.

The relationship between suppliers and buyers has had significant changes in recent years. Among those suppliers are small and medium size enterprises (SMEs) providing machining services as demanded by their clients. Usually this type of company faces difficulties to adequately manage the selling price of services to be rendered. Larger companies on the other hand have the ability to quickly and more accurately manage their costs and related prices due to the utilization of expensive software which are often not viable for SMEs. This paper proposes a procedure based on the contribution margin concept which enables the SMEs dedicated to supplying machining services to perform an economic analysis of the machining process as a way to improve the efficiency of its cost management and pricing of their services.

A numerical simulation method is developed to simulate the process of wellbore heat transfer during injecting carbon dioxide by amending the classical heat transfer modelRamey models. It analyses how the selected parameters affect the distribution of the wellbore temperature and pressure, which include CO2injection temperature, pressure and density, the injection flow rate and Joule Thomson coefficient. The results show that, CO2injection temperature has greater impact on the initial level of the temperature distribution; higher injection pressure raises the temperature mainly because of the effect of Joule Thomson coefficient; also, when the injection process lasts a longer time, the distribution is much more stable. When the injection flow rate is higher, the strata temperature has less influence on the flow temperature. The injection pressure and density has very appreciable effect on the pressure distribution. However, the other parameters have less influence on it. The modified simulation method was applied in Jiangsu Caoshe oil field and the simulation results coincided with the measuring data well.

The "Excellence Engineers Education and Training Program" is one of the major reform projects that the Ministry of Education of the People's Republic of China (PRC) is implementing for the "National Plan for Medium and Long-term Education Reform and Development (2010--2020)"[1]. Based on "3+1 Program" of talents training mode for the "Excellence Engineers Education and Training Program", the framework for cooperative education was devised, in which science and engineering, theory and practice, academia and industry are comined to prepare students who not only create, design, and build, but understand the nature and behavior of the materials used in the building. To the end, the knowledge system of material science and engineering, including the necessary basic and characteristic professional knowledge, was proposed on the basis of the talents training experience exceeding ten years.

A Simple Numerical Solution Procedure for Equations of Nonlinear Finite Element Method

Published: February 2014

The conventional solution strategy for nonlinear FEM of structural analysis is usually based on Newton-Raphson iteration under an additional constraint equation. So far a lot of nonlinear finite element solution procedures have been devised to provide the basis for most nonlinear finite element computer programs. In order to produce effective, robust solution algorithms, additional constraint equations for nonlinear FEM calculations in the load-displacement space of has been extensively investigated for the last a few decades. However, it is widely believed that due to the additional computations in the controlling of steps and directions of the iteration procedure, there will be more round-off errors accumulated to influence the convergence of solution. In this work, a more simplified solution procedure is presented, which is featured to be with neither iterations nor constraints. A Fortran computer program of the algorithm presented has been implemented in combining with a space truss element of co-rotational procedure. Verification of the procedure has been done by numerical example and a good result achieved.

In order to make on-orbit maintenance easy, a division method for the orbital replaceable unit (ORU) of manned spacecraft is proposed. Selection range of ORU was determined based on analyzing on-orbit repair requirements of system. Then a logic judgment strategy for ORU division was established to obtain a preliminary partition scheme, and the verification method is used to adjust the scheme of ORU division. Finally, the proposed method is applied on a subsystem of a manned spacecraft and the partition scheme can ensure the balance of system performances, which indicate that the proposed method can provide a feasible approach to engineering implementation.
