Norms are generally recognized as standards of behaviour and effective means to control and coordinate agents' activities. The development of a multi-agent system requires organizing the system in such a way that the standards of behaviour , represented by a set of norms, are actually followed by the agents. In this talk, I present an operational approach for organizing the overall multi-agent ...

objective: breast cancer comprise approximately one third of malignant cases in women and is considered as the most common invasive condition in women at an age range of 15-54 years and as the second most prevalent cause of mortality at an age range of 55-74 years. tumor inhibiting factor p53 is a vital homeostatic regulator and its inactivation at the related gene or molecule could lead to tum...

Many interesting Web-based AI problems require the ability to collect, store and process large text datasets. To address this problem, we have developed Slashpack, an integrated toolkit for collecting and managing hypertext data. Currently, we are using Slashpack to study the effectiveness of tagging as a mechanism for organizing and searching blogs, and also to study community structure in the...

In this study, we explore a semi-automatic construction of a faceted vocabulary, which can be used as a mechanism for organizing Web-based resources. Based on the analysis of the manual process of faceted vocabulary construction, we modeled a hybrid approach to facet generation that integrates the strengths of manual and automatic methods.

We present the design and evaluation of a fully decentralized software application discovery scheme – iDiscover, which is used in the iShare Internet-sharing system being built at Purdue University. The scheme employs a structured peer-to-peer (P2P) overlay routing mechanism and a hierarchical name space. The structured P2P routing mechanism is self-organizing and scalable. The hierarchical nam...

In this study, we explore the construction of a faceted vocabulary that can be used as a mechanism for organizing Web-based resources. After analyzing the manual process of faceted vocabulary construction using an existing organizational structure to identify heuristics for automating the construction process, we modeled a hybrid, semi-automatic approach to facet generation that integrates the ...

Present work introduces a probabilistic recognition scheme for hand gestures. Self organizing feature maps are used to model spatiotemporal information extracted through image processing. Two models are built for each gesture category and, along with appropriate distance metrics, produce a validated classification mechanism that performs consistently during experiments on acted gestures video s...

Store-operated Ca(2+) entry is a widely encountered mechanism for generating cytoplasmic Ca(2+) signals. From a whole-genome screen in HeLa cells, a new study reveals that cytoskeletal septins play a critical role in this process, by organizing signaling structures in the plasma membrane.
