This paper presents a new efficient algorithm for fitting an ellipse to scattered points. By minimizing the algebraic distance subject to the constraint of length of semi-minor axis, the new approach incorporates the ellipticity constraint into the normalization factor. The proposed method guarantees an ellipse-specific solution even for the noised data spaning a small section of the elliptic arc...
Index is used to improve the efficiency of database queries. Because the database needs to handle very large amount of data, while the memory is expensive, limited capacity, and the database must meet certain real-time, finding an effective design approach of the index is very necessary. This paper describes that through the B and T tree performance analysis during the process of designing the index,...
This paper proposed a whole new design for RV40(realvideo40) video decoder from FFmpeg(fast forward Moving Picture Experts Group),which is in lack of the ability to decode smoothly when decoding a period of high bit rate frames within some video streams. The design specially optimized the sub pixel interpolation algorithm, which is the core of motion compensation. The design uses detailed, different...
Web service composition,which compose existing Web service to satisfy the application requirement, become the key of the enterprise integration application in network.But existing Web service composition is mostly based on syntax ,it is very difficult to compose Web services together in heterogeneous with syntax but in accord with function.In order to resolve the heterogeneity between Web services...
To fully address the problem of developing a polyculture milkfish farming strategy which optimizes the profits while keeping the water clean, research is divided into three phases. First, the Holling Type III is applied to build the All-Natural Model to simulate the original ecosystem when water quality was agreeable for coral growth. Then after analyzing the monoculture system, a conclusion is reached...
For a lot of producers have never saved materials of their products for aims of economizing their time and saving costs, but when they have received orders, they will start from their locations with their production lines travel first to the material supply regions, second to the ordered regions, and product their products on the travelling time. Here, we consider their minimum travelling time routing...
The paper established a mathematical model of integrated optimization of the navigation performance for a high-speed ship, improved the genetic algorithm to a new parallel genetic algorithm based on the sensitive variable, and applied to an integrated optimization problem of high-speed ship navigation performance. Compared with GA, the optimization results indicate that the improved parallel genetic...
The novel compact folded Yagi antenna, for its high gain and superiority in small size, is being interested in various electromagnetic application areas. But for its complex structure, as well as the strong coupling among the elements, making the optimization and design rather difficult. In this paper, the impact of multi-scale semi-solutions to the final performance of antenna is taken into account,...
Scheduling policy in host operating system (OS) will have effect on the performance of Kernel-based Virtual Machine (KVM). This paper proposed an optimized scheduler policy to improve the performance of KVM. Firstly, a special process queue for virtual machine (VM) is added in the host OS, which is scheduled prior to normal process. Same time slices is given to each VM to make their load balanced...
Considering the existing service composition model are almost focused on single service composition efficiency, did not consider about the global efficiency and lack of capability of evaluation of inhibition of malicious evaluation, this paper propose a global efficiency optimization of service composition model based on equivalent hierarchical and design a selection of appropriate policy to solve...
Foundation pit engineering is composed of some inter-related and relatively independent sub-engineering which makes it possible to introduce the distributed parallel optimal method into foundation pit engineering design. Based on the genetic algorithm with intrinsic parallelism, a distributed three-level co-evolution model and its corresponding algorithm, which can realize collaborative optimal design...
A novel approach for microwave imaging of the dielectric objects in free space using hybrid particle swarm optimization (HPSO) is presented in this paper. A scattering model based on the method of moment and the asymptotic waveform evaluation (AWE) is used to solve the scattering problem in this paper. The error between measured field and computed field is considered as the object function. The inverse...
The software of auto-tuning parameters of PID control is developed for industrial controller. The output response curve of control system is recognized, and the scopes of the controller parameters are given to meet expected control index by fuzzy tuning rules based on pattern recognition. The PID parameters are optimized by means of genetic algorithm based on the optimization function of over-shoot,...
Particle Swarm Optimization (PSO) is a new paradigm of Swarm Intelligence which proposes that the co-operation of individuals promotes the evolution of the swarm. Recently, a modified Particle Swarm Optimizer (MLPSO) has been succeeded in solving truss topological optimization problems with continuous design variable and competitive results were obtained. Since most of structural problems involve...
According to the criterion of minimal Expected Cost of the Repair sequence (ECR), the optimizing model of Battlefield Damage Repair (BDR) sequence based on Bayesian networks has been established in this paper. The model has changed the traditional mode of static repair sequence, and meets the Battlefield Damage Assessment and Repair (BDAR) demand of speediness and high-efficiency. Furthermore, the...
Support vector machine (SV machine, SVM) is a genius invention with many merits, such as the non-existence of local minima, the largest separating margins of different clusters, as well as the solid theoretical foundation. However, it is also well-noted that SVMs are frequently with a large number of SVs. In this paper, we investigate the number of SVs in a benchmark problem, the parity problem experimentally...
Hysteretic optimization (HO) is a recently proposed optimization method based on the well-known demagnetization process of magnetic materials in physics. In this study, we apply HO to the protein folding problem, an attractive problem in computational biology, by generalizing the external field. The experimental results with benchmark problems show the proposed method is competitive with other popular...
The selection of reasonable machining parameters in numerical control milling process is the key issue to improve quality and productivity of product as well as save cost. In order to determine the optimal machining parameters instead of conservative ones used at present, a method of machining parameters management based on process planning knowledge was introduced in this paper. On the basis of analysis...
In this paper, I attempt to model for finding the optimal arrangement of providing phone service to a "Pseudo US". Taking the considerations of several social consequences, regarding providing phone service to the "Pseudo US" as a multi-objective programming problem, an optimization model is constructed in several different optimal methods including AHP and a more objective one-Fuzzy...
