High-speed police pursuits and the inherent risk of injury and death that can resuit constitute an important law enforcement and public safety issue. Police pursuits are dangerous. Available data indicate that the number of pursuits continues to increase, as well as the number of pursuit-related injuries and deaths. A traffic accident constitutes the most common terminating event in an urban pu...

Power consumption is a key point in the design of high-speed switched capacitor (SC) circuits, which allow to efficiently implement a number of analog functions. Among them, SC Σ∆ modulators are very popular for A/D conversion: in this kind of circuits, operational amplifiers are the most consuming cells because of their requirements in terms of DC gain and unitygain frequency. A new amplifier ...

The Lighthill acoustic analogy indicates that substantial noise reduction is possible in high-speed jets by reducing the radiation efficiency. This entails reducing the convective Mach number of the eddies whose footprint is sensed in the near pressure field. In dualstream jets, local reduction in convective Mach number is possible by inducing asymmetry in the plume that redistributes the most ...

The performance of public-key cryptosystems like the RSA encryption scheme or the Diffie-Hellman key agreement scheme is primarily determined by an efficient implementation of the modular arithmetic. This paper presents the basic concepts and design considerations of the RSAγ crypto chip, a high-speed hardware accelerator for long integer modular exponentiation. The major design goal with the R...

In this paper, we present a high speed pairing coprocessor using Residue Number System (RNS) and lazy reduction. We show that combining RNS, which are naturally suitable for parallel architectures, and lazy reduction, which performs one reduction for more than one multiplication, the computational complexity of pairings can be largely reduced. The design is prototyped on a Xilinx Virtex-6 FPGA,...

The acoustic sound level caused as secondary effects of industrial energy conversion processes is often perceived as an unwelcome noise emitted into the enclosing surrounding. In order to verify design aspects for reducing such undesirable noise emission in particular within variable electric speed drive applications, suggested novel combinations of electrical and mechanical motor topologies ar...

Turbo codes achieve the highest coding gain known and should be the best candidates for error correction in high-speed wireless systems. However, the standard implementation of their decoding algorithm suffers from a large latency and high power consumption making them improper for mobile interactive systems. To overcome this drawback, we systematically analyzed the Maximum A Posteriori algorit...

The signal integrity of the circuit, as one of the important design issues in high-speed digital system, is usually seriously affected by the signal reflection due to impedance mismatch in the DDR3 bus. In this paper, a novel optimization method is proposed to optimize impedance mismatch and reduce the signal reflection. Specifically, by applying the via parasitic, an equivalent model of DDR3 h...

While drivers’ speed behaviour has been widely studied, only marginal attention to the speed behaviour at intersections has been dedicated and more research is needed. Aim of this study was: (1) to evaluate if the intersections significantly affect drivers’ speed along the major road; (2) to quantify this interaction in terms of both speed change at the center of the intersection and speed prof...
