Further Applications of Sector-Based Detection and Short-Term Clustering

by Guillaume Lathoud , 2006
"... This paper presents an effective implementation of detection-localization of multiple speech sources with microphone arrays. In particular, the Scaled Conjugate Gradient descent is used for fast and precise localization, within a pre-detected volume of space, and a close to realtime implementation ..."

Distributed source coding for sensor networks

by Zixiang Xiong, Angelos D. Liveris, Samuel Cheng - In IEEE Signal Processing Magazine , 2004
"... n recent years, sensor research has been undergoing a quiet revolution, promising to have a significant impact throughout society that could quite possibly dwarf pre-vious milestones in the information revolution. MIT Technology Review ranked wireless sensor networks that con-sist of many tiny, low- ..."

Credit Card Fraud Detection with a Neural-Network,”

by Sushmito Ghosh , Douglas L Reilly - Proc. 27th Hawaii Int‟l Conf. System Sciences: Information Systems: Decision Support and Knowledge-Based Systems, , 1994
"... Abstract Using data from a credit card issuer, a neural network based fraud detection system was trained on a large sample of labelled credit card account transactions and tested on a holdout data set that consisted of all account activity over a subsequent two-month period of time. The neural netw ..."

experience indicates that a factor of 10 increase in speed is achieved when this pre-screening network is used. The Mellon FDSm fraud detection system has been fully operational since March 3, 1993. In-field performance consistent with or better than that of the feasibility study reported in this paper

Accelerated, High-Quality Refraction Computations for Volume Graphics

by Shengying Li, Klaus Mueller , 2005
"... We present an efficient framework for the high-quality rendering of discretely sampled surface-based objects with refractive effects. This requires an accurate estimation of the refraction coefficients, paired with efficient and accurate surface detection, space traversal, and backdrop image samplin ..."

Membrane flow during pinocytosis. A stereologicanalysis

by Ralph M. Steinman, Scott E. Brodie, Zanvil A. Cohn - J Cell , 1976
"... HRP has been used as a cytochemical marker for a stereologic analysis of pinocytic vesicles and secondary lysosomes in cultivated macrophages and L cells. Evidence is presented that the diaminobenzidine technique (a) detects all vacuoles containing enzyme and (b) distinguishes between incoming pinoc ..."

Predetection Fusion in Large Sensor Networks with Unknown Target Locations

by Ramona Georgescu, Peter Willett, Stefano Marano
"... Fusion of multisensor data can improve target probability of detection but suffers from a potentially increased false alarm rate. The optimal sensor decision rule in the case of multiple sensor systems and known target location is of course a likelihood ratio test. This approach, however, is not app ..."
Abstract - Add to MetaCart
is motivated by the need for an efficient way to process the volume of data from large sensor networks that consist of low quality sensors. We thus propose predetection fusion as a contact sifting procedure followed by an Expectation Maximization step that refines the location of the estimated detections

Collision Detection for Continuously Deforming Bodies

by Thomas Larsson, Tomas Akenine-Möller, Thomas Larsson Ý, Tomas Akenine-möller Þ , 2001
"... Fast and accurate collision detection between geometric bodies is essential in application areas like virtual reality, animation, simulation, games and robotics. In this work, we address the collision detection problem in applications where deformable bodies are used, which change their overall sh ..."

Several heuristics for updating the trees due to deformations are compared to each other. By combining a top

Measurement of Kidney Volume with Multi-Detector Computed

by unknown authors
"... The determination of kidney size is important in clinical field, because it can facilitate to make decisions on the management strategy.1 Of several indexes of kidney size, kidney length was traditionally used because it can conveniently be measured using ultrasonography (US). However, considering t ..."
Abstract - Add to MetaCart
the complexity of the kidney shape, kidney length can not appropriately represent kidney mass. Additionally, kidney length, as measured by US, is prone to interobserver variability and poor repeatability.2 Kidney volume is a more sensitive index of kidney size than kidney length for the detection of renal
