This paper de nes a hierarchy of human supervisory mediation levels into a robotic system This interaction creates a semi autonomous system which should enable completion of all feasible tasks We propose that the increased interaction between the supervisor and all lev els of a robotic system will permit a human supervisor to maintain the system in a stable state We have in corporated these hie...

The sea breeze/land breeze circulation system in the Los Angeles a r ea results in transport of pollutants seaward at nigh t followed by return of aged material inland the next day . This characteristic wind reversal pattern both increases the r etention time available for the oxidation of S02 to form sulfates and causes individual a ir parcels to make mul tiple passes over large coas tal emiss...

In this paper we describe CALVIN an immersive multimedia approach to applying virtual reality in ar chitectural design and collaborative visualization em phasizing heterogeneous perspectives These perspec tives including multiple mental models as well as mul tiple visual viewpoints allow virtual reality to be ap plied in the earlier more creative phases of design rather than just as a walk thro...

Spatial data mining i e discovery of interesting implicit knowledge in spatial databases is an important task for understanding and use of spatial data and knowledge bases In this paper an e cient method for mining strong spatial association rules in geographic infor mation databases is proposed and studied A spatial association rule is a rule indicating certain association relationship among a...

OBJECTIVE To evaluate the efficacy and safety of transpapillary papilloplasty in patients with choledocholithiasis. MATERIALS AND METHODS All endoscopic retrograde cholangiopancreatography (ERCP) procedures performed at Hospital Ana Costa, in the city of Santos, Brazil, over the last five years were retrospectively evaluated using the hospital's information database. The success of the proced...

Work ows are activities involving the coordinated execution of mul tiple tasks performed by di erent processing entities mostly in distributed het erogeneous environments which are very common in enterprises of even moderate complexity Centralized work ow systems fall short to meet the demands of such environments This paper describes the design and implementation of a distributed work ow manag...

Huge amounts of data available in a variety of digital forms has been collected and stored in thousands of repositories However the information relevant to a user or application need may be stored in mul tiple forms in di erent repositories Answering a user query may require correlation of information at a semantic level across multiple forms and representations We present a three level archite...

An Active grid-based method for estimating pass regions from broadcast soccer videos is presented in this paper. It is assumed that the pass region has a high probability of the pass succeeding. In soccer matches, players discover pass regions based on previous and current player positions. In conventional methods, pass regions are estimated by applying Active Net to only a single frame of a so...
