The main aim of this paper is to develop a client/server based model for computing the weighted Moore-Penrose inverse using the partitioning method as well as for storage of generated results. The web application is developed in the PHP/MySQL environment. The source code is open and free for testing by using a Web browser. Influence of different matrix representations and storage systems on the...

Repeatedly transfused thrombocytopenic patients frequently form antibodies directed against human leukocyte antigens (HLA) and become unresponsive to random donor platelet transfusions. Although exposure to foreign antigens borne on donor leukocytes appears necessary to provoke primary sensitization, the stability of leukocyte antigens during routine platelet storage is largely unknown. Accordi...

Abstract Distributed (Cloud) Storage Systems (DSS) exhibit heterogeneity in several dimensions such as the volume (size) of data, frequency of data access and the desired degree of reliability. Ultimately, the complex interplay between these dimensions impacts the latency performance of cloud storage systems. To this end, we propose and analyze a heterogeneous distributed storage model in which...

In this paper we make the case for microsearch, an architecture in which Web search capabilities are added to a user’s local PC. We demonstrate that the substantial storage and computing capacity of a user’s local computer can be used to index the World Wide Web directly on the PC. Compared to traditional purely centralized search, microsearch enables a new class of search-based applications, i...

Several pattern classifiers give high classification accuracy but their storage requirements and processing time are severely expensive. On the other hand, some classifiers require very low storage requirement and processing time but their classification accuracy is not satisfactory. In either of the cases the performance of the classifier is poor. In this paper, we have presented a technique b...

We describe the design rationale for a hardware tamper resistant secure storage system based on probe storage with a patterned magnetic medium. This medium supports normal read/write operations by magnetising individual dots perpendicular to the media plane. We report on an experiment to show that in principle the medium also supports a separate class of read/write-once operations by allowing i...

Sufficient conditions under which a class of nonlinear discrete-time systems which are non-affine in the control input and the states can be rendered locally dissipative are derived. Two methodologies in order to render nonlinear single-input single-output discrete-time systems locally dissipative are given. Dissipativity is seen as a “perturbation” of the storage energy invariance or the feedb...

This paper presents a new class of erasure codes, Lincoln Erasure codes (LEC), applicable to large-scale distributed storage that includes thousands of disks attached to multiple networks. A high-performance software implementation that demonstrates the capability to meet these anticipated requirements is described. A framework for evaluation of candidate codes was developed to support in-depth...

We present new algorithms for computing orders of elements, discrete logarithms, and structures of finite abelian groups. We estimate the computational complexity and storage requirements, and we explicitly determine the O-constants and Ω-constants. We implemented the algorithms for class groups of imaginary quadratic orders and present a selection of our experimental results. Our algorithms ar...
