Composition of Web Services Based on Data Dependency Specification
Authors: Lixin Quan
Published: March 2012

As the number of available Web services is steadily increasing, there is a growing interest for reusing basic Web services in new, composite Web services. However, most current Web services choreography proposals, such as BPEL4WS or WSCI, need a fixed execution flow previously designed by human, thus the adaptability of Web services can not be fully used. Through formalizing the description of single Web services, a Web services composition mechanism based on dependences between data is developed and a flexible and self- adaptable workflow model to compose Web services automatically is proposed. Furthermore, the method of verifying the integrity and consistency of data is given, so that the model is more easily saleable.

Authors: Soltani Mohammad Amin Zare , Haghighat Abolfazl Toroghi , Rashidi Hassan , Chegini Tahere Godarzvand
Published: March 2012

Visual Sensor Networks (VSNs) are special kind of Wireless Sensor Networks (WSNs) that monitors an environment by camera devices. WSNs are constrained by limited energy. On the other hand, unlike most sensors, cameras are directional in their field of view (FOV). If a target is out of the FOV of a camera, it needs to spend some energy and turn to the target to cover it. The problem of covering known location targets in an area with at least k sensors in the networks while keeping energy consumption minimum, is an NP-hard problem. In this paper we applied the Harmony Search (HS) to overcome the problem. The proposed algorithm fulfills the two objectives. The first objective is the k-coverage satisfaction, and the second one is to minimize the sum of rotations of all sensors.

The Dynamic Relationship Between the Industrystructure and the Banking Credit-Structure in the Regional Economy of Zhejiang Province—An Empirical Study Based on VAR Model
Authors: Han Jin , Han Yifei
Published: March 2012

Based on the vector auto-regression model (VAR), the authors probed into the dynamic relationship between the industry-structure and the banking credit-structure in the regional economy of Zhejiang Province. As is shown by the results of the empirical study, the development of the tertiary industry in Zhejiang in the past 3 years chiefly results from the growth of the secondary industry and credit expansion. Even though a positive correlation between the industry-structure of Zhejiang and banking credit-structure, it is insignificant for banking credit-structure driving the adjustment of industry-structure. The reason might be that the distinct credit expansion in recent years is chiefly benefited by the secondary industry. It is thus suggested that governments should develop and issue supporting financial policies to help the tertiary industry acquiring more financial resources, since the tertiary industry is in the weak position in financial market and can not benefit from commercial banking services.

A Denoising Algorithm Baised on Nonsubsambled Contourlet Transform and Two-Dimensional Principle Component Analysis
Authors: He Kun-Xian , Wang Qing , Xiao Yan-Chang , Fan He , Wang Xiao-Bing
Published: March 2012

This paper proposes a novel image denoising algorithm which utilizes noise energy to perform image denoising based on Two-Dimensional Principal Component Analysis (TDPCA) in Nonsubsampled Contourlet Transform (NSCT) domain. The NSCT can capture the edges of natural images efficiently, and at the same time, it can get rid of the Gibbs effect. The noisy image can be decomposed by the NSCT into directional subbands. The TDPCA is then used to estimate the noise energy (local threshold) for the image blocks in high frequency subbands. The soft threshold shrinkage can hence be employed on the NSCT coefficients without estimating the noise variance. At last, the inverse NSCT is carried out on the modified coefficients to obtain the denoised image. The denoising algorithm is validated by numerical experiments on two typical images. Numerical results show that the proposed method is superior both in vision and in PSNR to former methods.

Published: March 2012

This paper discusses on the available literature on data mining in Medical applications. A categorization has been provided based on the data mining function implemented, and the preference criterion selected by the model. The usage of compressed ECG for fast and efficient Tele cardiology application is crucial, as ECG signals are enormously large in size. In this paper, we are demonstrating an innovative technique that performs real-time classification of CVD. Our proposed system initially uses data mining techniques, such as attribute selection (i.e., selects only a few features from the compressed ECG) and expectation maximization (EM) based clustering. These data mining techniques running on a hospital server generate a set of constraints for representing each of the abnormalities. Then, the patient's mobile phone receives these set of constraints and employs a rule-based system that can identify each of abnormal beats in real time.

For an accurate evaluation of the injured area in forensic medical image, four image segmentation methods including iteration threshold segmentation, Otsu method, Local threshold segmentation, K-means clustering segmentation are presented. The comparison of four image segmentation methods to get experimental data is necessary. The numerical measurements are required to tag the injured region by segmentations to partition the foreground and background and the mathematical morphological processing is used to smooth the edges and eliminate the holes and spots in the image. Then the calculation of the area by counting the pixels of injured region by scanning of the image is proposed. Therefore, the effective procedure of the area measurement for arbitrary shapes in forensic medical image is given. The result shows that four methods are effective to segment the forensic medical image and the three errors in the injured area of them are less than 0.5%.

Authors: Alsharaa Buthayna , Bataineh Sameer
Published: March 2012

Ad hoc networks are a collection of mobile nodes communicating via wireless channels without any fixed infrastructure or centralized administration. With the increase of the number of users and large amount of traffic to be exchanged, the demand for scalable routing protocols has increased. This paper presents a scalable routing protocol, based on AODV protocol, called Clustered Ad Hoc Routing Protocol (CARP). CARP achieves scalability by means of two techniques. First, by dividing the network into clusters and isolating local traffic within these clusters from global connections aboard. And second, by modifying the route discovery phase of AODV and making only bases and borders involved instead of all nodes in the networks. The evaluation methodology and simulation results obtained showed the effectiveness of CARP in local communications, where it outperforms AODV in terms of Packet Delivery Fraction (PDF), Control Routing Load (CRL), and Average End-to-End Delay (AEED). On the other hand, CARP also showed its superiority in global communication, where the CRL, in all cases, was always less than that of AODV.

Reverse water—hammer, a well known phenomena occurring in hydropower plants due the closures of the guides vanes and fail in pump work in generally considered unwanted in system, because creates steam bubbles( cavitation ) are not able to withstand the higher pressure and they condense releases pressure peak of up to some hundred MPa occur. Using water as source of green energy reduces the air pollution problems that cause the global warming. We propose using reverse water-hammer for a mechanical instrument (reciprocating engine) to collect this natural energy. The engine comprises from plunger being push up with sudden close of the water way by it, which was connected with guiding system to reverse it back. The plunger used in the present study is vertical, transparent water tank attached with the mechanism which allows one to easily observe the continuing steady plunger reciprocating motion made by the force of air-water. We are measured the transient pressure peak from our experimental rig. The solutions of unsteady axisymmetric and compressible Navier-Stokes equations and linearized state equation of water are validated with experimental data collected. The compare with theoretical results shows that the numerical validation can be used to predict the maximum pressure peak from reverse water-hammer for laminar flow and would agree with measurement.

This paper investigates experimentally the variations in pressure distribution in the hydrodynamic journal bearing system for different sets of loads, speeds and lubricants. This paper mainly consists of two parts, first part of theoretical calculations and experimental readings. second part of simulation. In the theoretical calculations, pressure distribution of journal bearing is calculated using Reynolds's equation. In experimental work practical pressure distribution developed in journal bearing system is measured on test rig. Test is performed at different set of loads and speeds using SAE20W40, SAE90, SAE140 and water as lubricants. The collected experimental data of pressure distributions are employed as training and testing data for an artificial neural network. The neural network is a feed forward network. Back propagation algorithm is used to update the weight of the network during the training. finally, neural network predictor has predicted pressure distribution which is in close agreement with practical pressure distribution given by test rig.

Published: March 2012

In this paper a new method is presented for voltage sag source location based on directional overcurrent (DOC) relay information. In this method the current (during sag and presag) is the only variable which is measured by relay/power quality (PQ) monitor. Then relative location of voltage sag source is determined using the variation of the magnitude of measured current positive-sequence component and the sign of its phase-angle jump. The performance of the proposed method is compared with distance relay (DR) and phase change in sequence current (PCSC) methods by using PSCSD/EMTDC and MATLAB on a large scale actual regional network including transmission and sub-transmission levels. The results show the good performance of the new method and its unique applicability in cases where only currents are recorded.
