Although in principle independent of any particular messaging protocol, Web Services are primarily accessed using SOAP over HTTP in practice. As SOAP provides no message security at all, other ways of securing messages are necessary. This paper summarizes the most important security model for SOAP, WS-Security, and its related specifications. We explore the advantages of one particular approach...

This paper describes a distributed implementation of a scalable heterogeneous associative logic programming model, and describes an abstract instruction set for the distributed version of the model. Associative computation exploits data parallel computation. The implementation uses PVM for architecture independence, and uses object oriented programming for modularity and portability. Performanc...

Wide-bandwidth measurements are necessary when testing electronically switched drfves. 7 b o dfficult pmblems are addressed the measurement of motor phase input power at low speed. with a high PWM modulation frequency and the measurement of small torque ripple (superlmposed on a large mean toque). In an electrlcdlY noisy envlronment. Extensive use Is made of dlgilal signal processing techniques...

the image blurring is caused by motion and out of focus parameters and type of blur can be classified as global blur and local blur. In this paper the most challenging spatially varying blured detection schemes are proposed.In this the blur detection techniques for digital images are used in order to determine the blur detection several classifiers are used. In this paper we reviewed SVM & DCT ...

Here we respond to some comments by Alday concerning headedness in linguistic theory and the validity of the assumptions of a mathematical model for word order. For brevity, we focus only on two assumptions: the unit of measurement of dependency length and the monotonicity of the cost of a dependency as a function of its length. We also revise the implicit psychological bias in Alday’s comments...

 Defragmentation is a fundamental resource management service allowing Reconfigurable Computing Systems (RCSs) to efficiently utilize resources when tasks are dispatched dynamically. Only well orchestrated interactions between the components of the reconfigurable resource management system can sustain the highest possible performance level for applications running on these RCSs. While scheduli...

This abstract provides an overview of the experimental work carried out at the MARHIS network formed by the Barcelona and the Santander research laboratories. The emphasis is on the role played by extremes as hydraulic drivers and also in terms of the observed responses. This has implications for the experimental generation equipment (waves, currents, wind) and for the observed responses (morph...

We first present a literature review of heuristics and metaheuristics developed for the problem of coloring graphs. We then present a Greedy Randomized Adaptive Search Procedure (GRASP) for coloring sparse graphs. The procedure is tested on graphs of known chromatic number, as well as random graphs with edge probability 0.1 having from 50 to 500 vertices. Empirical results indicate that the pro...
