Abstract: In order to easily port mobile applications suitable for each platform, that have been developed under diverse development environment for individual wireless communication service providers, or redevelop them on a specific platform, it is required to reuse them at software model level that is a software development paradigm for MDA (Model Driven Architecture). Verification of existing design models and test models for the study, mainly checking (Model Checking) with a code-based software designed to define in the abstract syntax tree or on the models generated using refactoring on design models for refinery operations and define how to perform. The problem with these traditional research methods, but the first model, design model for checking the information with the model by defining a formal representation in the form of an abstract syntax tree, as you've shown how to perform verification of the model to perform refactoring. Additional steps need to define more complex due to a software problem that is not the way to the model suitable for optimization refactoring. In this paper, as defined in the MDA-based model transformation studies of a reusable model transformation patterns, abstract factory pattern and the bridge pattern given the pattern information automatically through the software model offers a way to perform refactoring..

Abstract: So far most research of human behavior recognition focus on simple individual behavior, such as wave, crouch, jump and bend. This paper will focus on abnormal behavior with objects carrying in power generation. Such as using mobile communication device in main control room, taking helmet off during working and using umbrella in high place. In global environment, there are some almost fixed features for portable objects of workers, such as clothes. So we adopted edge detecting by color tracking to recognize object in worker. The sequence of 3D human behavior data would be expressed by geometric character of skeleton and its angle. Since specific time and space of behavior definition, it is of importance for recognition system using describing information in a comprehensive way. Take account of information complementary perspective, this paper introduced a method of making decision from multi-information by spatial pyramid and fisher score discretion for behavior recognition. And the method was proved to have advantages than some previous algorithms.

Abstract: In this paper, the synthesis and investigation of the glass in the Al2O3- ZrO2-SiO2 system, to be used in dental field. The mechanism of powder–state becoming a solid state block during the laser sintering process was disclosed by scanning electron microscope (SEM) and energy dispersive X-ray (EDX) analysis on powders and sintered samples. The optimal parameters of laser and can be obtained by the study. The results allowed us to affirm that the characteristics of this glass, in comparison with the tooth hard substances and other commonly employed inorganic dental materials, recommend it for further utilization in the dental field.

Abstract: A integrated analysis methodology(IAM) based on incidence matrix is presented in the paper, aiming at the independent and imbalance between maintainability analysis (MA) and maintenance task analysis (MTA) in practical projects. This paper presents correlativity between support resources and maintenance task, support resources and maintainability factors, maintainability and maintenance task to achieve the process oriented integrated analysis based on incidence matrix, which can expose design defects effectively. Besides, the methodology puts forwards the compositive measures for design improvement through screening key problems and common problems from analysis results. A simple case study is used to demonstrate how the methodology is more effective than usual.

Abstract: A thermal power valve workshop applying the integrated technology of green planning for workshop layout and machining operations (GPIT) has been constructed from the demands of enterprise development. The key technology is to model the full life cycle production for the typical products in the workshop and carry out a green planning for the whole workshop. By the attribute analysis of the resource consumption and environment impacts, some adaptive processes of green manufacturing and prototypes of processing devices are developed for the physical productions in the valve workshop. The green planning and optimal operation for the workshop production is implemented and the remarkable environmental and economic benefits are gained.

Abstract: This study aimed at investigating the characteristics and equilibrium of Penicillium sp. QQ biosorption bacteria Exiguobacterium sp. TL. The optimal biosorption conditions were as follows: 50 mM Fe3+, 2.50 g of strain QQ, 480.80 mg/L of strain TL, 120 min of contact time, pH 5 and 40oC. The biosorption isotherms of strain TL by strain QQ could be well described by both Langmuir and Freundlich models. The maximal biosorption capacity of strain QQ for TL was 62.62 (mg/g) at 40oC, evaluated by Langmuir isotherm. It could be concluded from the results that the strain QQ was a promising biological carrier for the biosoption of strain TL, and the establishing of fungi-bacteria biosorption system was potential for pollutant removal and field application.

Abstract: An optical fiber sensor based on attenuated total reflectance (ATR) for extraction chemical information from highly scattering turbid materials has been evaluated. The influence of particles on bulk absorption and ATR transmitted spectra of micron-sized graphite flakes and spherical glassy carbon suspensions were investigated. The ATR transmitted spectra of coiled fiber-optic sensor in those suspensions with various concentrations are insensitive to scattering of suspended particles, especially for graphite flake suspensions. The reason for different influence of graphite flakes and spherical glassy carbon particles suspensions on e ATR spectra analyzed. This study demonstrates that fiber-optic sensor based on ATR technique is a feasible technique in application for monitoring turbid suspensions.

Abstract: in this paper, analysis of the fluid dynamics was carried out on hot air in drying mechanism of a gravure printing machine by applying the fluid dynamics and aerodynamics theories. The kinematical equation and the kinetic equation were established respectively and the RNG model was added according to flowing conditions of hot air. The CFD analysis model was established by adopting the computational fluid dynamics (CFD) method to implement dynamic simulation analysis on air hot in the drying mechanism. Uniformity of drying was improved through adding clapboard and a flow guide plate to optimize the structure of air nozzles, so that the hot air convolutes for multi times on substrate and the utilization efficiency was increased.

Abstract: Several kinds of methods of energy management of hybrid electric vehicle (HEV) are analyzed. Based on the design requirement of a certain type of parallel HEV, the fuzzy control strategy of energy management is proposed. ADVISOR2002 is chosen as the simulation platform for secondary development, and the simulation results of the fuzzy control strategy and electric assist control strategy are compared. The simulation results indicate that the adaptive fuzzy controller can obviously improve the performance of HEV fuel economy and emissions.

Abstract: This work describes the platinum-group metal electrocatalytic materials were synthesized by incipient wetness impregnation process combine with aqueous solutions of H2PtCl6, Pd(NO3)3 and Rh(NO3)3 that were coated on alumina substances employed as a model reaction test by ammonia (NH3) electrocatalysis oxidation (ECO) research for fuel cell applications. The electrocatalytic materials were characterized by dynamic light-scattering (DLS), with a particle size around nanoscale particle sizes with high dispersion phenomena. Further, ECO ability was determined by using cyclic voltammetry (CV) and linear sweep voltammograms (LSV) technique. The experimental results show that the significant reactivity of the PtPdRh ternary electrocatalysts in acid medium and the results also demonstrated that the potential and the current density of the main oxidation-reduction peak change for the PtPdRh ternary electrocatalyst.
