CASTOR (the CERN Advanced STORage system) is used to store the custodial copy of all of the physics data collected from the CERN experiments, both past and present. CASTOR is a hierarchical storage management system that has a disk-based front-end and a tape-based back-end. The software responsible for controlling the tape back-end has been redesigned and redeveloped over the last year and was ...

This paper investigates the effect of temperature on a hybrid energy storage system with various energy management systems. The hybrid energy storage system consists of a fuel cell, ultracapacitor and battery with associated DC/DC and DC/AC converters. The energy management strategies employed are the state machine control strategy, fuzzy frequency/logic decoupling strategy, minimization strate...

Online grooming is an activity that leads to sexual abuse of children. For this reason a number of pieces of legislation governing grooming have been created on international and national levels. The present paper discusses a specific case that has received a lot of public attention and been regarded as a high-profile grooming case in Sweden. This particular case is of special interest for the ...

The rapid advances in the computer industry allow building larger systems that require mass storage volumes. As storage space increases, its management becomes increasingly difficult. In contemporary enterprise storage systems, performance has developed into a major bottleneck, which negatively affects the overall IT performance. Centralized solutions are often infeasible and thus a distributed...

We describe an architecture of an enterpriselevel storage control system that addresses the issues of storage management for storage area network (SAN) -attached block devices in a heterogeneous open systems environment. The storage control system, also referred to as the “storage virtualization engine,” is built on a cluster of Linux-based servers, which provides redundancy, modularity, and sc...

In this extended abstract, we explain a demo of the leakage-resilient authentication and data (key) management system which can be regarded as a prominent solution for secure cloud storage.

A storage management scheme is described that supports the invalidation of addresses to freed storage and thus, in that sense, provides a secure system. Unlike previous virtual memory techniques, the allocated areas of our scheme can vary from the very large, requiring multiple pages of storage, to the very small, in which several can be contained on a single page. Special treatment is accorded...

This paper proposes a virtual memory management system suitable for interactive continuous media applications. Our virtual memory management system enables continuous media applications to reserve physical memory for allocating pages as soon as possible when the applications require the pages. The system implicitly and incrementally allocates and wires pages used for processing timing critical ...

Since 1980, the Society for Information Management (SIM), in a joint effort with different universities, has conducted an annual survey of the key issues facing IT executives. Over time, these studies have expanded to include questions about spending, workforce, sourcing, reporting relationships, performance measurement, and various other IT organizational and management practices. They also ex...

Cloud Computing provides facilities for storage, management, processing, and accessing information and other data stored in several system, platforms, applications etc . The above work represents the implementation of electronic hospital management system which enables date storage, update, retrieval, modification through cloud using the virtual private network which enhances the security of th...
