Efficient, Decentralized Detection of Qualitative Spatial Events in a Dynamic Scalar Field
This paper describes an efficient, decentralized algorithm to monitor qualitative spatial events in a dynamic scalar field. The events of interest involve changes to the critical points (i.e., peak, pits and passes) and edges of the surface network derived from the field. Four fundamental types of event (appearance, disappearance, movement and switch) are defined. Our algorithm is designed to r...
متن کاملDecentralized Detection of Topological Events in Evolving Spatial Regions
Qualitative information about topological events, like the merging or splitting of spatial regions, has many important applications in environmental monitoring. Examples of such applications include detecting the emergence of “hot spots” in sea temperature around a coral reef; or the break up and dispersion of an environmental pollution spill. This paper develops and tests an efficient, decentr...
متن کاملA Novel and Efficient Hardware Implementation of Scalar Point Multiplier
A new and highly efficient architecture for elliptic curve scalar point multiplication is presented. To achieve the maximum architectural and timing improvements we have reorganized and reordered the critical path of the Lopez-Dahab scalar point multiplication architecture such that logic structures are implemented in parallel and operations in the critical path are diverted to noncritical path...
متن کاملVibrotactile Detection, Identification and Directional Perception of signal-Processed Sounds from Environmental Events: A Pilot Field Evaluation in Five Cases
Objectives: Conducting field tests of a vibrotactile aid for deaf/deafblind persons for detection, identification and directional perception of environmental sounds. Methods: Five deaf (3F/2M, 22–36 years) individuals tested the aid separately in a home environment (kitchen) and in a traffic environment. Their eyes were blindfolded and they wore a headband and holding a vibrator for sound id...
متن کاملLead Field Scalar and Loop Spatial Electrocardiography
Spatial electrocardiography based on the lead field concept of McFee and Johnston appears to be theoretically more satisfactory than other systems of vectorcardiography. To determine the normal range of planar loop patterns to be expected with this technic and to compare them with those derived by previous methods, a survey of young adult males has been carried out with particular reference to ...
