This paper formalizes the concept of similarity which has been used on an ad hoc basis by
application engineers to provide more flexibility in concurrency control. We show how the …

Nowadays, one of the most challenging design issues of battery-driven real-time embedded
systems is how to reduce energy consumption such that the battery life can be prolonged …

Internet traffic is bursty and network servers are often overloaded with surprising events or
abnormal client request patterns. This paper studies a load shedding mechanism called …

Making critical sections abortable is a promising approach to reducing priority inversions. To
improve the schedulability of a system using abortable critical sections, the maximum …

The difficulties of providing a guarantee of meeting transaction deadlines in hard real-time
database systems lie in the problems of priority inversion and of deadlocks. Priority inversion …

There has been growing interest in the performance of transaction systems that have
significant response time requirements. These requirements are usually specified as hard or …

Hard real-time database systems (RTDBS) must provide a guarantee that real-time
transactions meet their deadlines. To preserve data consistency, hard RTDBS require …

In this paper, we are interested in energy-efficient concurrency control for real-time tasks on
a non-ideal DVS processor. Based on well-known ceiling-based concurrency control …

In this paper, an energy-efficient scheduling algorithm, called ceiling-based conditional
abortable scheduling (CB-CAS) algorithm, is proposed to schedule periodic hard real-time …

Predictable performance in the event of failures is of paramount importance in most safety
critical real-time database systems. Our research addresses new crash recovery techniques …
