To deal with the problem of premature convergence and slow search speed, this paper proposes a novel particle swarm optimization (PSO) called self-adaptive escape PSO, which is guaranteed to converge to the global optimization solution with probability one. Considering that the organisms have the phenomena of escaping from the original cradle when they find(More)
To study the protective role of Baicalin on rats thymus with severe acute pancreatitis (SAP). The SAP rats were randomly assigned to the model control, Baicalin treated and Octreotide treated groups. Normal rats were assigned to the sham-operated group. The rat survival rates, pathological changes of thymus, apoptotic indexes and expression levels of(More)
Software cost estimation has played an important role in software development since its emergence in 1960's. Based on a classification of algorithmic model based methods, non-algorithmic model based methods and composite methods, the typical software cost estimation methods in history are overall reviewed. The issue of software sizing, which is closely(More)
active measurement model for software process control and improvement. Abstract: This paper presents an active measurement model (AMM) for software process control and improvement, and the related measurement method. AMM formally describes the goal, feature, and indicator of software process, and their relationship. AMM also provides some principles,(More)
The technology of detecting the edge of lateral vehicle by Sobel algorithm based on FPGA in vehicle collision avoidance system (VCAS) is proposed in this paper. In general, Sobel operator is an image edge detector, which is realized by programming and implemented on the microprocessor. To simplify the complex structure of the VCAS and decrease the(More)
To evaluate the feasibility and advantages of constructing a novel tissue engineering bone, using β-tricalcium phosphate (β-TCP) and rat adipose-derived stem cells (ADSCs), modified with BMP2 and BMP7 by lentivirus. In the present study, ADSCs transfected with Lv-BMP2 and Lv-BMP7, alone or together, were seeded on β-TCP scaffold and cultured in vitro. Based(More)

Many methods for mapping XML to relations have been proposed without considering the semantics of XML data before. But the semantics is very important to design schemas for storage, optimize queries, and check update anomalies, etc. In the presence of XML FDs which are specified over DTDs, this paper presents a method based on the hybrid inlining to map XML(More)
The IIR filter design under the mixed-criterion of H/sub 2/ norm and /spl infin/ norm is proposed in this paper, and genetic algorithms (GA) is introduced to realize the filter design based on such criterion. By this approach, the disadvantage of other conventional methods is avoided and the satisfied performance of the designed filter is obtained. The(More)
based software process control and improvement model. Abstract: CMM/CMMI (capability maturity model/CMM integration) has been accepted since 1999 by Chinese software organizations, and widely used since then. But there are limited number of CMM/CMMI users in China. By launching a survey, problems of using CMM/CMMI are identified, and the negative impact is(More)
