Abstract: Sheet forming is a high-volume fabrication method for producing lightweight materials components. An important goal in manufacturing research is to determine the optimum method for producing products with less cost. In this paper, combined with the orthogonal test method and finite element method (FEM) simulation, the analysis was carried out to analyze the key process factors such as stamping force, fillet radius, and friction coefficient. Using orthogonal test method can reduce the testing time, learn how the molding parameters influence the total equivalent plastic strain, acquire the best match forming parameters, and give guidance for the better condition

Abstract: In this paper single crystal alloys [111] orientation on tensile stress creep performance testing and organization was observed, on the high temperature and low stress conditions, combining with the creep characteristics of SEM observation, organizational morphology constructed raft shape g in 3d space ordered phase mode of existence of; Study the single crystal alloys [111] orientation in high-temperature creep of tensile stress during directional coarsening regularity, and using the finite element method, this paper analyzes the monocrystal [111] orientation in ni-based alloy cubic / two-phase interface von Mises stress distribution and the lattice strain energy change rule, through the immune genetic algorithm analysis [111] orientation of single crystal alloy phase of evolution rule ordered .

Abstract: According to the constitutive relation of linear thermovisoelasticity, with the help of Laplace transformation method and the introduction of structure functions and thermal functions, the mathematical model and its corresponding variational principle for thermoviscoelastic FGM beams are set up on the basis of the assumption that plane section remains plane and normal to the beam axis. Using Laplace transformation method, the deflection and the stress distribution are discussed.

Abstract: The article briefly introduced the wearing characteristic and the test method of luminous fiber knitted fabrics, like comfortableness, fastness, and the luminous property. Finally use the fuzzy comprehensive evaluation method to analyze and estimate the wearing characteristic of luminous fiber knitted fabric. And then reach a kind of stitch with the optimum wearing characteristic.

Abstract: Human exposure to chloride ions in swimming pools has been recognized as a potential health concern. Although environmental monitoring is a useful technique to investigate chloride ions concentrations in indoor swimming-pool air, in practice, the interpretations of measured data would inevitably run into difficulties due to the complex interactions among the numerous variables, including environmental conditions and occupant activities. Consequently, the examination of chloride ions within swimming pool becomes an important test item for water quality control procedure. To effectively check the concentration of chloride ions in swimming pool, the evaluation process with an evaluation algorithm, indices of precision degree ( ), accuracy degree ( ) and the objective evaluation method with capability and concept of six sigma, proposed by Sung and Vännman are quoted in this paper to criticize examination tools for water quality in swimming pool. To ensure whether the evaluation method to measure chloride ion concentration in swimming pool holds precision, accuracy degrees and application functionality or not. The analysis results reveal that this method is suitable for examining the evaluation tool of chloride ions within swimming pool.

Abstract: polyethylenimine-modified mesoporous hybrid material with the polyethylenimine (PEI) containing 50 wt% was synthesized. It exhibits a high adsorption capacity of 210 mg/g-PEI.The adsorbed CO₂ could be desorbed completely from the sample at 150 oC.

Abstract: Experimental and numerical investigations of adhesively stiffened composite panels were performed to discuss the load-carrying capacity of different design at stiffener run-out. The compression experiment revealed that the failure was initiated at the edge of the run-out and propagated across the skin-stiffener interface. A fracture mechanical approach to utilize cohesive finite element was adopted in the numerical analysis of these specimens. It was shown that the finite element analysis using solid element and cohesive element was able to qualitatively predict the crack growth characteristics for each specimen

Abstract: Using circumferential constraint action of steel tube to concrete, steel tube concrete makes concrete be in the condition of three-dimensional pressure, to increase the strength of concrete and enhance the plastic performance. Due to the existence of the concrete could prevent or delay the steel tube from crippling, it makes steel tube material performance can be fulfilled. Steel tube concrete can not only make up two materials their shortcomings, but also give full play to the advantages of both. With high bearing capacity, good plasticity, convenience to construction and good refractory performance, and many other advantages, steel tube concrete make the loss in the fire reduced, and play a certain role in fire prevention and mitigation

Abstract: When the field of the hospital physical examination has entered the computerized era, people can use computers to store large amounts of physical examination information, greatly improving the efficiency of physical examination. However, with more and more examination items, it will bring about some bias if the doctors give physical examination findings for participants by subjective analysis, so the use of advanced software analysis technology is needed to help analyze and retrieve physical examination information. This paper mainly discusses the application of the Agent technology in the analysis of physical examination information.

Abstract: 8-hydroxyquinoline (8-Hq) films were electropolymerized on indium-tin-oxide-coated (ITO) glass slides by using cyclic voltammetry. The 8-Hq electropolymerized on ITO electrode (8-Hq/ITO) was immersed in a 5-mL solution containing 0.01 M phosphate buffer solution (PBS, pH 7.0), 0.8 mM cetyltrimethylammonium chloride, 20 µL of HAuCl4 (1%, w/w), and 50 µL of Au nanoparticle seeds. The mixture was incubated at 57oC for 3 h. Then Au nanoparticles were grown and deposited onto the 8-Hq/ITO electrode. It was found that some metal ions (Zn2+, Cd2+, Mg2+, and Pb2+) could inhibit the growth of Au nanoparticles. The metal-modulated growth of Au nanoparticles was studied by UV-vis spectra and differential pulse voltammetry.
