We describe an operational program that l o cates objects in a television image and traces their edges. The program accommodates the te levision camera, maximizing dynamic range during acquisit ion and sensi t iv i ty during t racing, to obtain the most appropriate image for each phase. If the trace routine loses an edge, various heurist ics diagnose the d i f f i c u l t y and tune both the ca...

The practical deployment of distributed agent-based systems mandates that each agent behave sensibly. This paper focuses on the development of flexible, responsive, adaptive systems based on Sensible Agents. Sensible Agents perceive, process, and respond based on an understanding of both local and system goals. Each agent is capable of (1) deliberative or reactive planning and execution of one ...

The LIM-only protein Lmo2, activated by chromosomal translocations in T-cell leukaemias, is normally expressed in haematopoiesis. It interacts with TAL1 and GATA-1 proteins, but the function of the interaction is unexplained. We now show that in erythroid cells Lmo2 forms a novel DNA-binding complex, with GATA-1, TAL1 and E2A, and the recently identified LIM-binding protein Ldb1/NLI. This oligo...

Human thermoregulation is achieved via autonomic and behavioral responses. Autonomic responses involve 2 synchronous 'components'. One counteracts large thermal perturbations, eliciting robust heat loss or gain (i.e., sweating or shivering). The other fends off smaller insults, relying solely on changes in sensible heat exchange (i.e., skin blood flow). This sensible component occurs within the...

Nowadays, geospatial information systems (GIS) are widely used to solve different spatial problems based on various types of fundamental data: spatial, temporal, attribute and topological relations. Topological relations are the most important part of GIS which distinguish it from the other kinds of information technologies. One of the important mechanisms for representing topological relations...
