Proceedings of the 2004 international symposium on Low power electronics and design, 2004
Power consumption is an important design issue of current embedded systems. It has been shown that the instruction cache accounts for a significant portion of the power dissipation of the whole chip. Several studies propose to add a cache (L0 cache) that is very small relative to the conventional L1 cache on chip for power optimization since a smaller ...

A slot assignment algorithm for exploiting temporal-spatial diversity in wireless hotspots
IET Conference on Wireless, Mobile and Sensor Networks 2007 (CCWMSN07), 2007This paper presents a distributed slot assignment algorithm from the angle of temporal-spatial diversity of concurrent transmissions to achieve high capacity in wireless hotspots. The unique characteristics of wireless hotspots, such as multiple interference links and many flows, are the key limitations in the existing wireless network technology ...

Hupo Kexue/Journal of Lake SciencesVisualizing Traffic Accident Hotspots Based on Spatial-Temporal Network Kernel Density Estimation
Proceedings of the 25th ACM SIGSPATIAL International Conference on Advances in Geographic Information Systems, 2017Understanding where traffic accidents occur is crucial for improving road safety and proper traffic enforcement allocation. One of the most common methods of analyzing traffic accidents is spatial hotspot detection. Existing hotspot detection methods, e.g., spatial scan statistics, spatial and spatiotemporal kernel density estimation, mostly focus on ...

Spatial and Temporal Hotspot Analysis of COVID-19 in Toronto
ABSTRACT The COVID-19 pandemic in Toronto, Canada was unequal for its 2.7 million residents. As a dynamic pandemic, COVID-19 trends might have also varied over space and time. We conducted a spatiotemporal hotspot analysis of COVID-19 over the first four major waves of COVID-19 using three different applications of Moran’s I to ...Afia Amoako +4 more

Spatial and temporal variability in Hawaiian hotspot volcanism induced by small-scale convection
Nature Geoscience, 2011be explained by the classical mantle plume concept. Here we present a numerical model of mantle plume upwelling beneath Hawaii. We find that small-scale convection in the ambient mantle can erode the base of the lithosphere, creating a washboard topography on the underside of the plate.

Freshwater Biology, 2014
Summary In streams, the creation of nutrient‐transformation hotspots by aggregated organisms may have heterogeneous and strong cumulative influences on stream nutrient dynamics. Here, we examine the potential for aggregations of freshwater mussels to create such hotspots.

Spatial–Temporal Variation of Bird Roadkill Hotspots in the Brazilian Semi‐Arid Region
Austral EcologyABSTRACT Birds are vulnerable to roadkill on highways. Understanding which factors may be associated with bird roadkill and the formation of roadkill hotspots is crucial for informing evidence‐based mitigation measures.

Biogeochemistry, 2009
Denitrification, the anaerobic reduction of nitrogen oxides to nitrogenous gases, is an extremely challenging process to measure and model. Much of this challenge arises from the fact that small areas (hotspots) and brief periods (hot moments) frequently account for a high percentage of the denitrification activity that occurs in both terrestrial and ...

Mapping Tornado Hotspots in the U.S.: Spatial and Temporal Analysis Across the U.S.
ACADEMIC JOURNAL ON SCIENCE, TECHNOLOGY, ENGINEERING & MATHEMATICS EDUCATIONTornadoes rank among the most damaging weather events in the US. They put lives at risk, wreck infrastructure, and upset economic systems. This study examines data from 1950 to 2022 using Geographic Information Systems (GIS) to uncover tornado hotspots, pinpoint high-risk areas, and grasp why some regions face bigger threats.
