Grid workflow schedule requires sophisticated expertise of domain in order to automate the process of managing workflows and its components. QoS-aware selection and execution of grid workflow can fulfill customer's expectations, a new preference method is proposed to design the grid workflow schedule. The grid workflow matching relation is achieved by mobile agent negotiation based on projection-join...
A major research within the multicriteria decision method field is focused on ranking the alternatives. Technique for order preference by similarity degree to ideal solution method is one of the methods for ranking the alternatives . The similarity degree is based on the distances of the alternative versus the two ideal solutions: positive ideal solution and negative ideal solution. This paper introduces...
This paper focuses on the multiple attribute decision making problems with the attribute values being numeric, interval and linguistic evaluations. The decision matrix is normalized by calculating the grey relation coefficients of the interval and linguistic attribute values to their corresponding positive ideal ones. Furthermore, a mathematical programming model is set up to figure out the attribute...
Stereo vision involves deriving scene depth from the differences in two images of a scene. It is classically formulated as a matching problem, with the results of matching easily translated to scene depth. Recent research has shown that the stereo vision problem can be represented as a succession of smaller problems, one of which is the problem of calculating the likelihood of two pixels matching...
Dimensionless analysis was applied to correctly evaluate the order of the factors affecting water -inrush from coal floor. In the evaluation of water -inrush from coal floor, many factors need to be considered. Thus, to correctly evaluate the order of the factors affecting water -inrush from coal floor is very important, which is the key to reasonable evaluation of water -inrush from coal floor. Based...
The risks associated with making decisions based on poor-quality information are quite high. Consequently, the management of information quality (IQ) and the quality of associated information management processes has become critical for healthcare organizations. An important first step in managing information quality is the ability to measure the risk of information products based on the quality of...
Based on ENDIF (ENhanced DIelectric layer Field), a new E-SIMOX high voltage device structure with the charge islands on the SOI and its breakdown mechanism proposed in this paper. The structure is characterized by the charge islands inserted on the top interface of silicon layer and dielectric layer. Inversion holes located by Coulomb's force enhance the electric field of the dielectric layer (EI...
Clustering is used commonly in ad hoc networks for hierarchical routing. Size-bounded clustering has been proposed to restrict the maximum size of a cluster so that the routing load, and hence the energy drain, on the clusterhead is bounded. However, all the existing size-bounded clustering algorithms take the size bound as the number of nodes in the cluster. This approach may still result in high...
This correspondence introduces a student LSI design contest http://www.LSI-contest.com/ which is annually held at Okinawa in March. Year 2009 contest was 12th anniversary. Applicants are not only from Japan but also from all over Asian countries. The main purpose of this contest is to develop LSI design skills for college students. This correspondence introduces LSI design contest from various aspects...
Cache memory is a usual architecture component, and has the function of increasing the system's performance. Cache, however, may be responsible for a large part of energy consumption (about 50%) of microprocessors. Based on this, the paper proposes an automated architecture exploration mechanism based on parameter variation of a cache memory hierarchy and NIOS II processor. Results based on Mibench...
Scattered data interpolation is an essential part of bidimensional empirical mode decomposition (BEMD) of an image. In the decomposition process, local maxima and minima of the image are extracted at each iteration and then interpolated to form the upper and lower envelopes, respectively. Because of the properties of radial basis function (RBF) interpolators, they are good candidates for use in BEMD...
Service applications are applicable to provide services for requests of users from network. Due to the fact that they have to endure a big number of concurrent requests, the performance of service applications running under specific arrival rate of requests should be assessed. To measure the performance of a service application, multi-party testing context is needed to simulate a number of concurrent...
A Machine learning technique called memory based bigram models are developed for a system that generate a simple sentence for Tamil language from a set of concept terms and their semantic role. This system consists of a learner to learn how to realize a sentence from the content of semantic role information. This learner has been designed as a statistical model that is formulated from a preprocessed...
A challenging task in data mining is the process of discovering association rules from a large database. Most of the existing association rule mining algorithms make repeated passes over the entire database to determine the frequent itemsets, which is likely to incur an extremely high I/O overhead. A simple but an effective way to overcome this problem is to sample the database, such that, it produces...
In this paper, we propose a decentralized adaptive output-feedback controller for a class of large-scale time-delay nonlinear systems with unknown high-frequency-gain signs. We establish global asymptotic stabilization results, without using Razumikhin Theorem or constructing Lyapunov-Krasovskii functionals. The paper enlarges the class of large-scale nonlinear systems for which global decentralized...
In this paper, we study the reliable decentralized supervisory control of discrete event systems (DESs) under the general architecture, in which the decision for controllable events employed is a combination of the conjunctive fusion and disjunctive fusion rules. For a plant equipped with n local supervisors, the notion of k-reliable (1 ?? k ?? n) decentralized supervisor is formalized and investigated...
First, a quantized progressive second price (PSP) auction mechanism called the Unique Limit Quantized - PSP (UQ-PSP) is presented for the allocation of fixed or timevarying quantities of a resource among arbitrary populations of agents. It is shown that (i) the states (i.e. bid prices and quantities) of the corresponding iterative dynamical auction system converge to a unique quantized (Nash) equilibrium...
Color selection in designing user interfaces is addressed by an interactive genetic algorithm. The proposed approach is aimed at finding the optimal trade-off between different and sometimes conflicting constraints, without any explicit model of user preferences and abilities. Experimentation investigates the algorithm convergence under several conditions and user behavior.
In this paper, we present a practical method of sentence ordering in multi-document summarization tasks of Chinese language. By using Support Vector Machine (SVM), we classify the sentences of a summary into several groups in rough position according to the source documents. Then we adjust the sentence sequence of each group according to the estimation of directional relativity of adjacent sentences,...
On-chip antennas are demanded to further lower the cost of wireless CMOS ICs. We placed an artificial dielectric layer (ADL) between an antenna and Si substrate to improve the antenna gain. A 3.1-10.6-GHz ultra-wideband inverted-F antenna with ADL as well as a low-noise amplifier were designed and fabricated using a 0.18-??m mixed signal/RF CMOS process with one poly and six metal layers. A fairly...
