Building Blue Stragglers with Stellar Collisions

, 2007
The evolution of stellar collision products in cluster simulations has usually been modelled using simplified prescriptions. Such prescriptions either replace the collision product with an (evolved) main sequence star, or assume that the collision ...

Collisions Between Gravity-Dominated Bodies: 1. Outcome Regimes and Scaling Laws

, 2011
Collisions are the core agent of planet formation. In this work, we derive an analytic description of the dynamical outcome for any collision between gravity-dominated bodies.

Ship Strike Risk for Fin Whales (Balaenoptera physalus) Off the Garraf coast, Northwest Mediterranean Sea

Frontiers in Marine Science, 2022
Ship strikes are a widespread conservation issue for many cetacean species globally. Population level impacts depend on the occurrence and severity of collisions, which may lead to life altering injuries or fatalities.

Collision-Resistance from Multi-Collision-Resistance

Journal of Cryptology, 2022
AbstractCollision-resistant hash functions ($$\textsf{CRH}$$ CRH ) are a fundamental and ubiquitous cryptographic primitive. Several recent works have studied a relaxation of $$\textsf{CRH}$$ CRH called t-way multi-collision-resistant hash functions ($$t\text {-}\textsf{MCRH}$$

Holographic phase diagram of quark-gluon plasma formed in heavy-ions collisions [PDF]

, 2012
The phase diagram of quark gluon plasma (QGP) formed at a very early stage just after the heavy ion collision is obtained by using a holographic dual model for the heavy ion collision.

Effects of acceleration on the collision of particles in the rotating black hole spacetime

, 2012
We study the collision of two geodesic particles in the accelerating and rotating black hole spacetime and probe the effects of the acceleration of black hole on the center-of-mass energy of the colliding particles and on the high-velocity collision ...

Work conjugate strain of virial stress

International Journal of Smart and Nano Materials, 2016
Certain stress tensor and strain tensor form a conjugate pair if there exists a scalar valued strain energy function such that the stress tensor is equal to the derivative of strain energy function with respect to the strain tensor.

Car collision avoidance with velocity obstacle approach [PDF]

, 2019
The obstacle avoidance maneuver is required for an autonomous vehicle. It is essential to define the system's performance by evaluating the minimum reaction times of the vehicle and analyzing the probability of success of the avoiding operation.
