Computer interfaces that support user recovery can radically alter a user's interaction style. Users can explore alternatives freely, secure in the knowledge that they can undo actions and restore previous states if necessary. A text-editor, like EMACS, where users can restore the state of an editing session to a correct previous state, is an example of such a system. Editors for textual, graph...

veloped with the general goal of quantifying the nature of the risk and to produce guidelines for the aerospace industry and chip manufacturers. A set of experiments is underway at the Los Alamos Neutron Science Center (LANSCE) in Los Alamos, New Mexico to provide data [9]. While a variety of different technologies will be tested, our interest here is specifically on an experimental Recoverable...

Advancements in technology have enabled many computer vendors to offer computer systems with gigabytes of memory at affordable prices. The availability of an abundance of real memory in a computer creates new opportunities for software designers — very large data objects can be made memory resident to support very efficient processing. However, crash recovery becomes more time consuming because...

The time evolution of a Munch pressure-flow translocation system is calculated using a numerical computer method. Results are obtained for the time course of the system variables following application of a large resistance in the translocation path, intended to simulate a cold block. The resistance factor required to produce translocation inhibition indicates that even moderate inhibition is pr...

The inherent redundancy and in-the-field reconfiguration capabilities of field programmable gate arrays (FPGAs) provide alternatives to integrated circuit redundancy-based fault recovery techniques. An algorithm for efficient runtime recovery from permanent logic faults in the Xilinx 4000 architecture has been expanded to include interconnect fault recovery and has been applied to a diverse set...

Computer forensics has recently gained significant popularity with many local law enforcement agencies. It is currently employed in fraud, theft, drug enforcement and almost every other enforcement activity. The research paper includes the types of attempts to destroy or tamper the files by the culprits and unleashes various recovery techniques, and their significance in different situations fr...

P. Krishna N. H. Vaidya D. K. Pradhan Computer Science Department Texas A&M University College Station, TX 77843-3112 Abstract In most research on checkpointing and recovery, it has been assumed that the processor halts immediately in response to any internal failure (fail-stop model). This paper presents a recovery scheme (independent checkpointing and message logging) for a multicomputer syst...

A computer network can be attacked in a number of ways. The security-related threats have become not only numerous but also diverse and they may also come in the form of blended attacks. it becomes difficult for any security system to block all types of attacks. this gives rise to the need of an incidence handling capability which is necessary for rapidly detecting incidents, minimizing loss an...

In the future, diierent database sites will be interconnected via gigabit networks, forming a very powerful distributed database system. In such an environment, the propagation latency will be the dominant component of the overall communication cost while the migration of large amount of data will not pose a problem. Furthermore , computer systems are expected to become highly reliable. In this...
