Induction motors are being used more than ever before in industry and individual machines of up to 10 MW in size are no longer a rarity. During start-up and other severe motor operations the induction motor draws large currents, produces voltage dips, oscillatory torque and can even generate harmonics in the power system [1 4]. It is therefore important to be able to model the induction motor i...

Real-time image processing at high frame rates could play an important role in various visual measurement. Such image processing can be realized by using a high-speed vision system imaging at high frame rates and having appropriate algorithms processed at high speed. We introduce a vision chip for high-speed vision and propose a multi-target tracking algorithm for the vision chip utilizing the ...

This observational study aimed to estimate the prevalence of speeding on urban roadways and to analyze associated factors. The sample consisted of 8,565 vehicles circulating in areas with and without fixed speed cameras in operation. We found that 40% of vehicles 200 meters after the fixed cameras and 33.6% of vehicles observed on roadways without speed cameras were moving over the speed limit ...

Many scientists analyze 3D biological data by counting cells and other structures. Our hypothesis is that an immersive environment is better for such tasks in terms of user speed and preference than a non-immersive environment. To help test our hypothesis, we designed and implemented an interactive visualization tool for a Cave and a Fish Tank virtual environment and conducted a user study in w...

This paper deals with fields of definition of the l-torsion points on the Jacobians of genus 2 hyperelliptic curves over finite fields in order to speed Gaudry and Schost’s point counting algorithm for genus 2 hyperelliptic curves up. A result in this paper shows that the extension degrees of the fields of difinition of the l-torsion points can be in O(l) instead of O(l). The effects of the res...

A high-performance configurable multi-channel counter is presented. The system has been implemented on a smallsize and low-cost Commercial-Off-The-Shelf (COTS) FPGA/DSP-based board, and features 64 input channels, a maximum counting rate of 45 MHz, and a minimum integration window (time resolution) of 24 μs with a 23 b counting depth. In particular, the time resolution depends on both the selec...
