A new resiliency scheme for a distributed database system with replicated data is presented.
One salient feature of the scheme is that it does not employ a log subsystem; hence, it can …

Several new algorithms that utilize wmt-for relations mduced by processes are developed for
deadlock avoidance in operating systems. One of the algorithms allows more concurrency …

A new resiliency scheme for distributed database systems with partitioned and replicated
data is presented. One salient feature of the new scheme is that it does not employ a log …

A concurrency control scheme using multiple versions of data objects is presented which
allows increased concurrency. The scheme grants an appropriate version to each read request…

A structural active-object system(SAOS) is a transition-based object-oriented system suitable
for rapid development of various concurrent systems. A SAOS consists of a collection of …

A typical database system maintains target data, which contain information useful for users,
and access path data, which facilitate faster accesses to target data. Further, most large …

This paper deals with the serializability theory for single-version and multiversion database
systems. We first introduce the concept of disjoint-interval topological sort (DITS, for short) of …

A structural active-object system (SAOS) is a transition-based object-oriented system suitable
for rapid development of hardware logic simulators. A SAOS consists of a collection of …

In a manufacturing system, machines, robots and storage areas are used as serially-reusable
resources. If the usage of these resources is not properly controlled, deadlocks may occur. …

Biological collections are gaining recognition as priceless sources of information about the
historic distribution and diversity of life. The Internet is emerging as the major venue for …
