In modern micro-architectures, computation speed is often reduced by cache misses. Cache analysis is therefore imperative to obtain effective optimization. We present an analytical technique based on reuse distances that focuses on efficiently determining the behavior of fully associative caches and extends to set-associative caches. In this technique, the number of cache misses is obtained by ...

With the continuous increase of Internet link speed and the number of flows, flow statistics has become a challenging task due to the demanding requirements on both memory size and memory bandwidth. In this paper, we propose a DIScount COunting (DISCO) method, which is designed for both flow size and flow bytes counting. For each incoming packet, DISCO increases the corresponding counter assign...

The current study tested the development of working memory involvement in children’s arithmetic strategy selection and strategy eYciency. To this end, an experiment in which the dual-task method and the choice/no-choice method were combined was administered to 10to 12-year-olds. Working memory was needed in retrieval, transformation, and counting strategies, but the ratio between available work...

Automated people counting has multiple applications: referring passengers to vehicles with empty seats, gathering statistical information for railway companies to improve their distribution of vehicles, etc. In this paper, a people counting algorithm for public transport vehicles is presented. First, head-shoulder contours are detected by adaboost classification of a combination of a histogram ...

We introduce a new property for geometric graphs: the local diameter. This property is based on the use of the region counting distances introduced by Demaine, Iacono and Langerman as a generalization of the rank difference. We use it as a characterization of the local density of the vertices. We study the properties of those distances, and show that there is a strong relation between region co...

Microchannel plate photon counting, imaging sensors with cross strip readouts having 18 mm active area format in sealed tube (optical sensing) configurations have been constructed. These have been tested with custom high-speed field programmable gate array based electronics for single event position and time encoding. The Super-GenII photocathodes used have response from 400 nm to 900 nm and pe...

Chikungunya virus was quantitatively assayed by counting immunofluorescent foci after infection of BHK21/C13 cell monolayers. The speed and efficiency of virus attachment to cells were markedly enhanced when augmented by centrifugal force. By this procedure, a proportionality was obtained between the number of immunofluorescent foci and the volume of inoculum. Virus penetration into cells was l...

Measuring fluorescence lifetimes of fast-moving cells or particles have broad applications in biomedical sciences. This paper presents a dynamic lifetime sensing (DFLS) system based on the time-correlated single-photon counting (TCSPC) principle. It integrates CMOS 192 × 128 avalanche diode (SPAD) array, offering an enormous photon-counting throughput without pile-up effects. We also proposed q...

Single-photon counting hybrid pixel detectors have shown to be a valid alternative to other types of X-ray imaging devices due to their high sensitivity, low noise, linear behavior and wide dynamic range. One important advantage of these devices is the fact that detector and readout electronics are manufactured separately. This allows the use of industrial state-of-the-art CMOS processes to mak...
