Abstract: Currently, there are many independent and closed "chimney" simulation systems in some range training systems, which is not only a waste of resources but incompatible with other systems well. In view of this situation, the paper focused on using of the testing and training architecture (TENA) that US developed to make improvements. According to the characteristics of TENA's architecture, the paper summarizes the framework to adapt the domestic simulation systems. Finally, the conclusion shows that it can indeed improves the performance of the system using TENA in the domestic simulation systems.

Abstract: Effect of pushing against soil of static driven Piles involve a series of problem, such as the large deformation and material non-linearity, etc. the research on its mechanism of action is still in the stage of exploration at present. In this paper, it attempts to analyze the problem of characteristic of development and change of stress and displacement in the process of extrusion and compaction of lateral soil of pile from the microscopic view when piles squeezed into soil. Based on the previous theoretical analysis and experimental results on the model, the two-dimensional particle flow code (PFC2D) is developed, the whole process of Static driven Piles continuous penetrate soil is simulated. The laws of soil displacements and stress changing with horizontal distance and depth during the process of pressing piles are obtained. Finally, the model results were compared with experimental results, and verified the applicability of the simulation results. In this paper, it reveals the regularity of movement of particles from the microscopic view in the process of static pressure piles Squeezed into soil, and it provide some reference for more complex microscopic simulation research of geotechnical engineering problems.

Page No: 52-65

Abstract: This paper presents the application of genetic algorithms (GA) for the optimum cost design of reinforced concrete continuous beams based on the standard specifications of the American Concrete Institute. The produced optimum design satisfies the strength, serviceability, ductility, durability, and other constraints related to good design and detailing practice. While most of the approaches reported in the literature consider steel reinforcement and cross-sectional dimensions of beam as design variables of the flexural aspect only, the dimensions and reinforcing steel in this research were introduced as design variables, considering the flexural, shear, and torsion effects on the beam. The constant parameters specified prior to the solution of the optimization problem included the number of bays, lengths of span, support conditions, loads, material properties, and unit costs. The forces, moments, and deformations needed in the GA constraints were determined from the analysis. The beam dimensions were corrected to the nearest 25 mm, and the areas of the longitudinal and transverse steel obtained from the design were converted into the least weight detailing of steel reinforcements. This conversion was achieved by generating a database of reinforcement templates containing different available reinforcement bar diameters in a pre-specified pattern, satisfying the user-specified bar rules and other bar spacing requirements. The optimum design results were compared with those in the available literature. Upon the illustration of an example problem and the presentation of results, the proposed optimum design model is concluded to yield rational, reliable, economic, and practical designs.

Abstract: Boiler efficiency is influenced by many factors. In order to find and realize optimum efficiency of boiler, the concept of controllable operating parameter is introduce to select the parameters and optimize them. Finally, 3 parameters are determined to participate in optimization, namely, excess air coefficient, exhaust gas temperature and main stream flow. Then this paper concludes the relationship between these parameters and boiler efficiency respectively. By using the function optimization algorithm based on genetic algorithm and nonlinear programming, the optimum scheme of boilers and calculate optimal solution of   is achieved, that is 93.110%.

Abstract: Based on the graph theory and immune algorithm, this paper produces a medicine delivery system in West Africa where the largest and most complex Ebola outbreak takes place. Firstly, the delivery destinations where vaccine or drug is badly needed are selected using the map of cumulative cases in different regions. Then the problem how to determine locations of distribution centers is transformed into a goal programming problem. In this model, object is defined as the minimum cost of delivery transport. The cost is calculated by the product of needed vaccine or drug in each destination and the distance from this destination to its potential delivery center. Finally, the goal programming problem is solved by immune algorithm. This model can also be used in other similar cases where such an optimized delivery system is needed urgently.

Abstract: Creating a bioactive cell-microenvironment and osteogenic functionality interface can be used for the surface modification of bone tissue engineering material, showing a good application prospect. In this paper, a bioactive and osteogenic functionality multilayer membrane with controllable amount of growth factors was fabricated by layer-by-layer assembly technique. Four biological macromolecules (casein, heparin, aidic fibroblast growth factor (aFGF) and collage I) were introduced onto the surface of polyurethane (PU) membrane. Flu-orescence intensity analysis and a toluidine blue assay revealed that the successfully multilayer membrane as-sembly process. The amount of aFGF loaded on membrane was regulated by changing the concentration of heparin, and aFGF can sustainably released from the membrane for 8 days. FDA staining and MTT assay showed that mesenchymal stem cells (hMSCs) on growth factors multilayer membrane fully spread and displayed more obvious proliferation behavior. These preliminary results collectively show a practical and simple assembly tech-nique, through which a bioactive and osteogenic material interface can be easily fabricated. This setup has the potential to be used for bone tissue engineering.
