Abstract: The objective of this article is to present the newest results of our research work. In order to determination and comparison of the fatigue resistance, high cycle fatigue tests (HCF) were performed both on SSAB WELDOX 700E (S690QL) quenched and tempered and VOESTALPINE ALFORM 960M (S960TM) thermomechanical high strength steels. Welded joints were made from these base materials, using gas metal arc welding (GMAW, MIG/MAG) with matching filler material. In the article, the performance of the welding experiments will be presented, especially with the difficulties of the filler material selection; along with the results of the HCF tests executed on the base material and its welded joints. Furthermore, our results will be compared with different literary data.

Abstract: In this paper, color coded structured light based on pseudo-random sequence is adopted, and a new decoding method is proposed. It includes three steps. First, the stripe centers are extracted through the use of peak detection. Second, the stripe colors are identified using k-means clustering algorithm on a new color feature with high discriminating power. This feature is related to the spectral sensitivity of red, green and blue sensors, the direction of the illumination source, the normal and albedo of the surface, and the spectral power distribution of the incident light, but it is insensitive to the intensity. Finally, a four-step matching method is presented in sequence matching, which is aim to match the subsequences with the length less than the window size. The experimental results show that our proposed decoding method has advantage of high accuracy.

Abstract: With the actual flight of the airplane model pictured by two theodolites, in this paper, a cross matching method of flight trajectory was proposed on the basis of horizontal projection, which was also checked and simulated in the research. The simulation proved that: within a certain measuring range, this cross matching method can effectively enable the matching calculations to flight trajectories of large numbers of equidirectional airplane models, thus to meet the measuring needs of the airplane model in flight.

Abstract: Matching analysis of automatic transmission fluid (ATF) and the hydraulic control system is an essential work for the development of ATFs used in automatic transmissions. Based on the hydrodynamic theory, an ATF model was built. By adopting the modeling concept of combining and establishing models with basic elements, the hydraulic control system model was built, and then complete matching model was built by introducing the ATF model into it. The matching level of the ATF and the hydraulic control system was evaluated, and the key parameters which influence the performance of the hydraulic control system and their proper values were defined, which will be reference for developing optimal ATFs. With the bench test result and vehicle test result on road, the matching method and models for ATFs with the hydraulic control system are confirmed to be effective and feasible, which can significantly shorten the development cycle of ATFs.

Abstract: In order to improve efficiency of the cutting tool in the practical production process and mend the phenomenon of disjunction between previous NC cutting tool matching and cutting tool management, integrate matching with management of cutting tool and regard Access as the backstage database and apply VC++6.0 software to develop database management systems of cutting tool matching and management. The production process of cutting tool efficient matching and the management process of cutting tool information is studied, according to the application requirements of system, then the function target of the system realization is established, the overall structure model of the system is constructed and the function and operation procedure of each functional module is designed.

Abstract: With the rapid development of spatial information technology and the increasingly artificial intelligence knowledge, MAS plays a more and more important role in conducting image segmentation.Considering the shortcomings of current segmentation method,a new algorithm based on MAS theory is proposed, It combines spectral and shape information in region merging.employer a number of agents to control the merging procedure in different regions and make the global merging control more optimal by utilizing the advantages of MAS,The results show that the algorithm is very effective for image segmentation both in urban and mountainous areas.

Abstract: In this paper, the GFC-KKM mapping is introduced and a GFC-KKM theorem is established in GFC-spaces. As applications, a matching theorem and a maximal element theorem are obtained. Our results unify, improve and generalize some known results in recent reference. Finally, an equilibrium existence theorem for systems of general quasiequilibrium problems is yielded in GFC-spaces.

Abstract: — The demand for simple, convenient and high security authentication systems protecting private information is rising with the development of improved consumer electronic devices. In existing systems cards, pin numbers and passwords are used for authentication. However theft of cards and guessing of pin numbers and passwords by exploiters is a serial threat. Hence the need to protect private information by means of biometric solutions is very essential. The proposed system finger vein recognition system is a biometric authentication system. The maximum curvature method of feature extraction used here extracts the centrelines without being affected by fluctuations in vein width and brightness. The results of processing are sent using GSM to owners or administrators. The system can be used for application such as bank ATM identification and verification, automatic door locking control systems and automated attendance register system.

Abstract: A typical parallel hybrid power system is briefly analyzed, and also its configuration is schematically depicted, on this basis some type of parallel hybrid power system is matched and analyzed in detail, with the foundation of vehicle transmission theory , calculation process given step by step, illustrated by a practical driving vehicle.

Abstract: People are paying more and more attention on driving comfort of their vehicle. This subject also draws more and more attention from the manufacturer. For cost and fix space reason, light trucks cab can hardly be designed to be float-type. So, good match for cab-mount system are the only available method. This paper is focus on matching analysis of cab-mount system. From parameters calculation to matching analysis, this paper provided a full chain of this method, which has great value of reference.
