A solution to the problem of integrating a recovering site inLo a distributed database system is presented. The basic idea used for the correct recovery is to maintain a consistent view of the status (up or down) of all sites. This view need not be the exact current status of the sites. but is the status as perceived by other sites. The session number is used to represent the actual state of a ...

This paper is the first in a series of two which reviews the contemporary British evidence-base relating to recovery in mental health over a 4-year period. This review uses a systematic approach analysing the British peer-reviewed literature relating to recovery and mental health. The second paper in the series reviews the non-peer-reviewed literature. Recovery is not a new concept; however, it...

the flow stress of steel depends significantly on microstructural changes taken place during hot deformation processes. in hot deformation processes, the flow stress of steel is influenced by two main metallurgical phenomena, i.e. recovery and recrystallization, along with its chemical composition and thermo-mechanical parameters. the final mechanical properties of steel are also determined by ...

Even though the automatic recovery techniques of workflow have attracted enough attention in recent years, several critical issues regarding the distributed recovery have not been addressed. For example, if we do the recovery under sustained attacks, in which condition the recovery can terminate? Is a synchronized clock necessary for distributed recovery? In this paper, we proposed a dead-lock ...

In this paper an efficient high step-up converter with a coupled- inductor with soft- switching operation is presented. The proposed topology includes a coupled-inductor boost converter for raising the voltage gain. Moreover, a simple auxiliary resonant circuit composed of an auxiliary switch, a clamping diode and a resonant tank (inductor, capacitor), is adopted in this paper. The coupled-indu...

This paper proposes a new approach to rollback-recovery for mobile-agent systems, and describes its implementation in the MESSENGERS mobile agents system. The used checkpointing method allows to implement space and time efficient, user-transparent rollback-recovery in heterogeneous distributed environments. Together with an efficient non-blocking system snapshot algorithm this checkpointing met...

The ethical implications of business continuity/disaster recovery planning, and technology is rarely a topic discussed within the academic or practitioner literature. However, ethical decisions permeate such business continuity and disaster recovery areas as data custody, privacy, and security issues involved in the control and possession of business continuity data. In this paper, a discussion...

improving the quality of medical images at pre and post-surgery operations are necessary for beginning and speeding up the recovery process. partial differential equations (pdes)-based models have become a powerful and well known tool in different areas of image processing such as denoising, multiscale image analysis, edge detection and other fields of image processing and computer vision. in t...
