Using Cd(NO(3))(2)·4H(2)O as a precursor and ethanol/water as the solvent, we synthesized Cd(5)(OH)(8)(NO(3))(2)(H(2)O)(2) nanowires and nanobelts through a simple solvothermal method. Unlike the conventional oil-water surfactant approach, the adopted method is biologically safe, simple and environmentally benign. The morphology and size of the obtained materials were studied by FESEM. The resu...

Dividing the total portfolio (parent) into non-overlapping sub-portfolios (children), and assuming homogeneity for both the parent and the children, we use a top-down dynamic default intensity model for the parent, and specify the conditional probability of default in the children given imminent default in the parent. We consider two fundamental cases which are building blocks of more complex a...

This paper formulates the problem of distinguishing changed from unchanged pixels in remote sensing images as a minimum enclosing ball (MEB) problem with changed pixels as target class. The definition of the sphere shaped decision boundary with minimal volume that embraces changed pixels is approached in the context the support vector formalism adopting a support vector domain description (SVDD...

We present a stream algorithm for large scale classification (in the context of l2-SVM) by leveraging connections between learning and computational geometry. The stream model [1] imposes the constraint that only a single pass over the data is allowed. We study the streaming model for the problem of binary classification with SVMs and propose a single pass SVM algorithm based on the minimum enc...

Kernel machines such as Support Vector Machines (SVMs) have been widely used in various data mining applications with good generalization properties. Performance of SVMs for solving nonlinear problems is highly affected by kernel functions. The complexity of SVMs training is mainly related to the size of a training dataset. How to design a powerful kernel, how to speed up SVMs training and how ...

The Metadata Encoding and Transmission Standard (METS) 1.x schema has an established community of users including academic and national libraries, archives, and museums as well as support from a number of commercial and open source tool and service vendors. While the established community of METS users has adapted systems and tools to METS expressed in XML, many in the library and archive commu...
