Efficient cache hierarchy management is of a paramount importance when designing high performance processors. Upon a miss, the conventional operation mode of a cache hierarchy is to retrieve back the missing block from higher levels and to store the block into all hierarchy levels. It is however difficult to assert that storing the block into intermediate levels will be really useful. In the li...

In recent years there has been an increased interest in the modelling and recognition of human activities involving highly structured and semantically rich behaviour such as dance, aerobics, and sign language. A novel approach is presented for automatically acquiring stochastic models of the high-level structure of an activity without the assumption of any prior knowledge. The process involves ...

We propose a general framework of a hierarchical structure, consisting of several levels of activities, for typical software related corporate hierarchy using multi-agent system. This work identifies the functionality of each level. Each and every level is considered as agent who is described further using fuzzy analysis. Our framework consists of six levels within which first five levels are c...

We present in this paper a combination of Machine Learning based Information Retrieval (IR) techniques and stochastic language modelling in a hierarchical system that extracts surface information from text. At the lowest level of this hierarchy, documents and paragraphs are successively routed with IR techniques. At the top level, a stochastic language model extracts the most relevant phrases, ...

Social interactions and relative positions within a dominance hierarchy have helped shape the evolution of reproduction in many animals. Since reproduction is crucial in all animals, and rank typically regulates access to reproductive opportunities, understanding the mechanisms that regulate socially-induced reproductive processes is extremely important. How does position in a dominance hierarc...

Motivation -Industrial firms survive, sustain and co-evolve by participating in the sector of innovation and production through industrial transactions with each other. However, it is difficult for specialized firms to be aware of and manage accordingly the kind of systemic constraints and opportunities induced by relevant but indirect transactions, as well as the technological and economic req...

This paper introduces behavioral rewrite systems, where rewriting is used to evaluate experiments, and behavioral productivity, which says that each experiment can be fully evaluated, and investigates some of their properties. First, it is shown that, in the case of (infinite) streams, behavioral productivity generalizes and may bring to a more basic rewriting setting the existing notion of str...

This paper reports on work on a structural health monitoring system done for NASA at North Carolina A&T State University. The system combines a multiagent system as the "brains" and a workflow system as the "brawn." Agents here typically serve as proxies for techniques with intensive communication and computation requirements. Agents negotiate to determine a constellation of techniques for solv...

This paper describes the principles of high level modeling of digital hardware circuits using the Extended Timing Diagrams (ETD) formalism which adds conditions, events, action expressions and particular constraints to traditional timing diagrams. Hierarchy and concurrency are integrated too such that a full top-down design becomes possible, enhancing in the same time the readability. While for...
