Multinomial logit (MNL) models have been applied extensively in the fields of transportation engineering, marketing and recreational demand modeling. So far, this type of model has not been used to estimate the proportion of crashes by collision type. Consequently, the objective of this study consists of investigating the applicability of MNL models for predicting the proportion of crashes by c...

Although there have been few collisions between ships and offshore installations, the grave consequences of such a collision has provoked the study of the probability of collision worldwide. A theoretical study is undertaken on the assessment of risk of collision in this paper. The causes of collision and the models of evaluating the risk collision are reviewed, which are then followed by some ...

In the n-body problem, a collision singularity occurs when the position of two or more bodies coincide. By understanding the dynamics of collision motion in the regularized setting, a better understanding of the dynamics of near-collision motion is achieved. In this paper, we show that any double collision of the planar equilateral restricted four-body problem can be regularized by using a Birk...

Dedicated short-range communication (DSRC) has been used in prototyped vehicles to test vehicle-to-vehicle communication for collision avoidance. However, there is little study on how collision avoidance software should behave to best mitigate accident collisions. In this paper, we analyse the timing of events and how they influence software-based collision avoidance strategies. We have found t...

In this paper we present an improvement of the collision attack [1] on the authenticated encryption mode of operation OCB. [1] presents a detection of collision method and a way to use the collision, and it is possible to use the information from a collision to change some blocks of the message unnoticed, if they have a special property. We found a way to use the information from a collision to...
