grid computing is an emerging computing paradigm that will have significant impact on the next generation information infrastructure. due to the largeness and complexity of grid system, its quality of service, performance and reliability are difficult to model, analyze and evaluate. this paper proposes a virtual tree-structured model of the grid service. this model simplifies the physical struc...

in synthetic aperture radar (sar) imagery, ship-sea contrast can be significantly improved when the polarimetric information is used, compared with information from a single channel sar. the constant false alarm rate (cfar) detection algorithm based on the alpha-stable (as) distribution model is a descent method for ship detection in sea. the most important step in this method is the parameter ...

A Knowledge Management (KM) System plays a crucial role in every industry as well as in Higher Learning Institutions. A RESTful resource is anything that is addressable over the Web. The resources can be accessed and transferred between clients and server. The resources can be accessed and transferred between clients and servers. Based on our earlier research works, we have developed a comprehe...

in this paper, a method to determine the material parameters of the lemaitre damage model from the knowledge of the gurson model parameters is proposed. as for porosity damage, the gurson model neglects the coupling of elasticity with damage, allowing to use the stress softening effect to make a link between both theories up to a fast identification procedure (based on the expressions of the yi...

This paper presents a new complexity metric for Object-Oriented (OO) design measurement to find at the design stage whether the classes become more complex, Moderate complex or less complex. The proposed metric is theoretically evaluated against the Weyuker’s properties as well as empirically evaluated against three open source software system. Furthermore, for validating the validity of new co...

This work addresses the fitting of 3D deformable face models from a single view through 2.5D Active Appearance Models (AAM). The main contribution of this paper is the use of 2.5D AAM that combines a 3D metric Point Distribution Model (PDM) and a 2D appearance model whose control points are defined by full perspective projections of the PDM. The advantage is that, assuming a calibrated camera, ...
