We study aging behavior of an aqueous suspension of Laponite as a function of concentration of Laponite, concentration of salt, time elapsed since preparation of suspension (idle time), and temperature by carrying extensive rheological and conductivity experiments. We observe that temporal evolution of elastic moduli, which describes structural build-up and aging, shifts to low times for experi...

Shortest path computation is required by a large number of applications such as VLSI, transportation and communication networks. These applications, which are often very complex and have sparse networks, generally use parallel labeling shortest path algorithms. Such algorithms, when implemented on a distributed memory machine, require termination detection methods; these methods consist of some...

The purpose of this research in the queueing theory is the theorem about the law of the iterated logarithm in multiphase queueing systems and its application to the mathematical model of the message switching system. First the law of the iterated logarithm is proved for the cumulative idle time of a customer. Finally we present an application of the proved theorem for the model of the message s...

RSA Data Security, Inc. is sponsoring contests to prove the (in-)security of miscellaneous cryptographic algorithms as DES or RC5. We have joined RSA’s RC5 contest by combining idle CPU power from users visiting a web site. Via an embedded Java RC5 applet down-loading and testing RC5 keys from the web server it was originating from, visitors can participate and donate idle CPU cycles without ha...

The increasing use of computers for saving valuable data imposes stringent reliability constraints on storage systems. Reliability improvement via use of redundancy is a common practice. As the disk capacity improves, advanced techniques such as disk scrubbing are being employed to proactively fix latent sector errors. These techniques utilize the disk idle time for reliability improvement. How...
