VEST is a set of four stream cipher families submitted by S. O’Neil, B. Gittins and H. Landman to the eSTREAM call for stream cipher proposals of the European project ECRYPT. The state of any family member is made of three components: a counter, a counter diffusor and a core accumulator. We show that collisions can be found in the counter during the IV Setup. Moreover they can be combined with ...

Nine-hundred and seventy-three police road-accident files describing overtaking accidents were sampled from the headquarters of Nottinghamshire Constabulary, England, for the years 1989–1993. Salient facts were extracted from each case, including the exact manoeuvre involved, the principle explanatory factors, the driver(s) most at fault, and the drivers’ ages. Two kinds of reliability measure ...

Injury Prevention recently published a commentary critical of epidemiological approaches to cycling safety. The author, Kary, suggests that our paper, which reanalysed Walker’s study of motor vehicle overtaking distance for cyclists, made false claims about type I errors and confused statistical significance and clinical significance. Kary supports this critique, along with other points in the ...

Abstract Highway users can apprehension to certain subjects with utilizing of Vehicular Ad-hoc Networks (VANET) applications if the rules for safe overtaking movement are violated make lane change maneuver between vehicles on highway road. In our research, we suggest an algorithm semi-automated S-AV compliant emphasize highway. The proposed technique classify into major categories and criticall...

This study investigated the control strategies and decision making of drivers who were executing overtaking maneuvers in a fixed-base driving simulator. It was found that drivers were frequently inaccurate in deciding whether it was safe to overtake in front of an oncoming vehicle. One source of error in this situation was the control strategy adopted by the driver; in several instances our dri...

VEST is a set of four stream cipher families targeted to semiconductor applications. All VEST family members support efficient encryption, single pass authenticated encryption, and collision resistant hashing in the one low area module. VEST was submitted by Synaptic Laboratories Ltd. to the ECRYPT NoE eSTREAM project in 2005. Recently, a single digit typographical error was identified in the V...

Overtaking is one of the most dangerous operations in driving. The rear-view mirror is sometimes not consulted by the driver or is momentarily useless because of the blind spot. This paper describes a simple FPGA system based on motion detectors of the fly and rigid-body detection that is able to efficiently segment overtaking cars using a sparse map of features from the visual field of the rea...
