Competition between individuals for resources which are limited and diverse in composition is the ultimate driving force of evolution. Classical studies of this event contend that the outcome is a deterministic process predicted by the growth rate of the competing types-a tenet called the Malthusian selection principle. Recent studies of competition indicate that the dynamics of selection is a ...

Emerging distributed multimedia applications have stringent performance requirements in terms of bandwidth, delay , delay-jitter, and loss rate. The Tenet real-time protocol suite provides the services and mechanisms for delivering such performance guarantees, even during periods of high network load and congestion. The protocols achieve this by using resource management, connection admission c...

Multimedia communication can be supported in an integrated-services network in the general framework of realtime communication. The Tenet Group has devised an approach that provides some initial solutions to the realtime communication problem. This paper attempts to identify the principles behind these solutions. We also describe a suite of protocols, and their implementations in several enviro...

According to a view widely held among philosophers of science, the notion of cause has no legitimate role to play in mature theories of physics. In this paper I investigate the role of what physicists themselves identify as causal principles in the derivation of dispersion relations. I argue that this case study constitutes a counterexample to the popular view and that causal principles can fun...

The Hippocratic Oath has guided the conduct of physicians for centuries. Inspired by its tenet of preserving privacy, we argue that future database systems must include responsibility for the privacy of data they manage as a founding tenet. We enunciate the key privacy principles for such Hippocratic database systems. We propose a strawman design for Hippocratic databases, identify the technica...

There is considerable interest in the network community in supporting real-time multi-party applications, such as video conferenc-ing. The Tenet Group at UC Berkeley and ICSI has designed and implemented protocols that provide quality of service (QoS) guarantees for real-time traac on packet switching networks. Suite 2 of the Tenet protocols provides scalable, exible and eecient network support...
