In most real world systems, objects vastly outnumbers threads. This paper shows how this characteristic can be used to implement efficient JavaTMmonitors in a way that reduces the number of needed monitors to be equal to the number of threads, while fulfilling the JavaTMsynchronized semantics. Some additional benefits related to priority inheritance and hierarchical resource locking will also b...

A web monitor is a program used to monitor some public HTML-based Internet information available from dynamic HTML documents on the Internet based on a user defined set of criteria. It is able to deal with public information available on the Internet on a single or multiple websites as a set of variables which the user uses to define some required notification conditions. The monitored informat...

In a global sense it is not difficult to agree that anyone wo contributes to the growth and development be it somatic, intellectual, educational or any other form is a mentor. There is no argument that the parents, teachers, coaches, special skill instructors and other similarly engaged individuals can collectively be viewed as mentors They probably instill more important formative traits than ...

Coordination of parallel activities on a shared memory machine is a crucial issue for modern software, even more with the advent of multi-core processors. Unfortunately, traditional concurrency abstractions force programmers to tangle the application logic with the synchronization concern, thereby compromising understandability and reuse, and fall short when fine-grained and expressive strategi...

Some properties of beamstrahlung are discussed, and plans to observe the effect at SLC by the use of Cherenkov counters are illustrated.

Distributed usage control is concerned with controlling how data may or may not be used after it has been given away. One strategy for enforcing usage control requirements is based on monitoring data usage and reacting to policy violations by imposing penalties. We show how to implement monitors for usage control requirements using runtime verification technology.

Many different monitoring systems have been created to identify system state conditions to detect or prevent a myriad of deliberate attacks, or arbitrary faults inherent in any complex system. Monitoring systems are also vulnerable to attack. A stealthy attacker can simply turn off or disable these monitoring systems without being detected; he would thus be able to perpetrate the very attacks t...

A person’s psychological well-being can be deduced by observing her past, current and future behaviors. However, little effort has been made to qualify, quantify and correlate a person’s behavior to her psychological well-being using nonintrusive health monitors. This report presents our attempts at using non-intrusive health monitors to observe a person’s diet, exercise and sleep patterns to d...

The authors argue that high self-monitors may be more sensitive to the status implications of social exchange and more effective in managing their exchange relations to elicit conferrals of status than low self-monitors. In a series of studies, they found that high self-monitors were more accurate in perceiving the status dynamics involved both in a set of fictitious exchange relations and in r...
