ÐThis paper discusses the self-collision avoidance problem in simulating the dynamic behavior of deformable cloth. It is not an easy task to simulate realistically the response of cloth in various types of complicated self-collisions. In this paper, the bounding box technique in addition to ordinary prechecking for collision detection is used to avoid self-collision. Instead of avoiding self-co...

Contemporary collision avoidance systems such as the Traffic Alert and Collision Avoidance System (TCAS) have proven their effectiveness in the Commercial Aviation (CA) industry within the last decade. Yet, TCAS and many systems like it represent attempts at collision avoidance that do not fully recognize the uncertain nature of a conflict event. Most systems circumvent probabilistic representa...

Forward collision occurs most frequently and involves the largest number of fatalities among various types of collisions in traffic accidents. Active research has been carried out to develop systems to avoid or mitigate forward collision. These systems are effective in reducing the number and the severity of occupant injuries, however, there is still margin for improvement, especially for reduc...

Visually guided collision avoidance is of paramount importance in flight, for instance to allow escape from potential predators. Yet, little is known about the types of collision-avoidance behaviors that may be generated by flying animals in response to an impending visual threat. We studied the behavior of minimally restrained locusts flying in a wind tunnel as they were subjected to looming s...

Collision Avoidance systems, as a subsequent step to collision mitigation, are one of the Great challenges in the area of active safety for road vehicles. In India the total annual deaths due to road accidents has crossed 1.18 lakh, according to the latest report of National Crime Records Bureau (NCRB). If these deficiencies are not controlled at early stages they might cause huge economical pr...

A multi‐ship collision avoidance decision‐making and path planning formulation is studied in a distributed way. This paper proposes a complete set of solutions for multi‐ship collision avoidance in intelligent navigation, by using a top‐to‐bottom organization to structure the system. The system is designed with two layers: the collision avoidance decision‐making and ...

This study examines attributes of virtual human behavior that may increase the plausibility of a simulated crowd and affect the user’s experience in Virtual Reality. Purpose-developed experiments in both Immersive and semi-Immersive Virtual Reality systems queried the impact of collision and basic interaction between real-users and the virtual crowd and their effect on the apparent realism and ...

The Traffic Alert and Collision Avoidance System (TCAS) has been shown to significantly reduce the risk of mid-air collision and is currently mandated worldwide on all large transport aircraft. Engineering the collision avoidance logic was a very costly undertaking that spanned several decades. The development followed an iterative process where the logic was specified using pseudocode, evaluat...
