Abstract: The networked control system typically introduces network delay that have not been considered at the design stage. As a consequence, the system performance is degraded with respect to the expected response. This thesis introduces a methodology to apply external gain assist networked control systems. The proposed methodology uses external gain to modify the controller output with respect to the current network traffic conditions in order to enable an existing controller for networked control systems and compensate the performance degradetion induced by network delay. This methodology can change existing traditional controller directly to network controller and not modify the original control algorithms.

Abstract: Hybrid multi-objective particle swarm algorithm is applied to vehicle routing problem and achieved good results, this paper based on the previous work, dynamic inertia weight is added to the particle swarm algorithm with intelligence factors, it improved the global search ability and the capacity of local convergence of the particle swarm algorithm; and the idea of immunity is introduced in the algorithm ,which makes the hybrid multi-objective particle swarm algorithm can effectively discard the repeated solutions in solving vehicle routing problems, this operation can improve the efficiency of the algorithm, and obtain better results under the same conditions.

Abstract: The μC / OS-II is a complete, portable, curing and cutting of preemptive real-time multitasking kernel. The strong task management capabilities provides a good platform for the multi-tasking system. Based on the analysis of the Chinese pinyin coding, according to the characteristics of the μC / OS-II real-time operating system, achieved a semi-intelligent pinyin chinese input use the small keyboard.

Abstract: The Information system need to handle a large number of Excel reports, while Excel is not easy to deal with large amounts of data and information extraction. The technology XML tag can be applied to describe data in a text file, using Extensible Style sheet Language (xsl),the XML Data Relationship was conversed to prepare for display. The same XML data allows a variety of different style sheets, the sheets can be flexible displayed in various ways, using XML technology to create and resolve data, Excel reports can be achieved flexible and efficient import and export.

Abstract: Affinity Propagation(AP)is a new clustering algorithm, which is based on the similarity matrix between pairs of data points and messages are exchanged between data points until clustering result emerges. It is efficient and fast , and it can solve the clustering on large data sets. But the traditional Affinity Propagation has many limitations, this paper introduces the Affinity Propagation, and analyzes in depth the advantages and limitations of it, focuses on the improvements of the algorithm — improve the similarity matrix, adjust the preference and the damping-factor, combine with other algorithms. Finally, discusses the development of Affinity Propagation.

Abstract: Processes are well defined sequences of computational steps executed in a coordinated manner that make application logic of an information system explicit. Process composition with shared resource is defined and analyzed in this paper. Conditions of structural soundness of composited process and conditions of property preserving of sub-process are presented.

Abstract: s paper presents a hybrid algorithm, the “particle swarm optimization with simulated annealing behavior (SA-PSO)” algorithm, which combines the advantages of good solution quality in simulated annealing and fast calculation in particle swarm optimization. As stochastic optimization algorithms are sensitive to its parameters, this paper introduces criteria in selecting parameters to improve solution quality. To prove the usability and effectiveness of the proposed algorithm, simulations are performed using 20 different mathematical optimized functions of different dimensions. The results made from different algorithms are then compared between the quality of the solution, the efficiency of searching for the solution and the convergence characteristics. According to the simulation results, SA-PSO obtained higher efficiency, better quality and faster convergence speed than other compared algorithms.

Abstract: Internet users will usually use search engine to find the relevant traveling information before planning the trip, and search for suitable hotels and book hotel accommodation rooms in advance through the internet reservation system .The hotel website search engine marketing strategy has become an important part of the hotel marketing management. The study found that " research and implementation methods have obvious actual benefit", “recommend to conduct some of the implementation methods prior to the building of Web site ", " in Blog Article Marketing, ‘Sina Blog " import flow is high ", "in Free Platform And BBS marketing, ‘PChome & ebay " import flow is high etc; Researchers suggest the hotel sites operators continue to implement the hotel Web sites search marketing in the future through methods such as "assist with paying keyword advertising marketing" and "add more links to external website", "set up their own official blog" and " and “conduct Facebook, Plurk Twitter marketing” and etc.

Abstract: Human induced pluripotent stem cells is promising for regenerative medicine and tissue engineering. In this chapter, we focus on the culture and characteristics of human induced pluripotent stem cells. The induced pluripotent stem cells were plated on murine embryonic fibroblast feeder cells and expanded in human embryonic stem cells media contained basic fibroblast growth factor. The cells were passaged by collagenase IV digestion method and observed under invert microscope. The expression of alkaline phosphatase was detected by immunocytochemistry. The cultured induced pluripotent stem cells grew well and stability with similar characteristics of human embryonic stem cells. These cells also expressed alkaline phosphatase. They formed embryoid body in feeder-free and suspension culture conditions. The results provide an experimental basis for improvement of induction study and further application to generate patient-specific induced pluripotent stem cells.

Abstract: Tetrandrine can inhibit the proliferation and collagen synthesis of fibroblasts in lung and liver tissue confirmed by a series of clinical research. In this chapter, we investigated the effect of Tetrandrine on the proliferation of human dermal fibroblasts derived from hypertrophic scars. The dermal fibroblasts were isolated from human hypertrophic scar tissues and cultured in vitro. Tetrandrine with different concentration were added to culture medium respectively. The proliferative activities were determined. The result show that when the concentration of added Tetrandrine increased from 5μg/ml to 80μg/ml, the proliferative activities of cultured dermal fibroblasts were decreased gradually in dose-dependent manner. It conclusions that Tetrandrine can obviously inhibit the proliferation of human dermal fibroblasts derived from hypertrophic scars.
