We present a new method to compute the energy Green’s function with absorbing boundary conditions for use in the calculation of quantum mechanical reaction probabilities. This is an iterative technique to compute the inverse of a complex matrix which is based on Fourier transforming time-dependent dynamics. The Hamiltonian is evaluated in a sine-function based discrete variable representation, ...

AIMS This article explores the laser-induced explosion of absorbing nanoparticles in selective nanophotothermolysis of cancer. METHODS This is realized through fast overheating of a strongly absorbing target during the time of a short laser pulse when the influence of heat diffusion is minimal. RESULTS On the basis of simple energy balance, it is found that the threshold laser fluence for t...

This paper presents a system to improve the protection to the occupants of a World Rally Championship Car in case of a side impact involving a tree collision using energy absorbing structures. An outline of the immediate events after the car crash into a tree are provided followed by an analysis of a typical standard rollcage, then the design criteria and features of a carefully selected design...

Currently the use of new materials is becoming more prevalent in vehicle industry for the lightweight design purpose. The design of engine hood is very important for pedestrian safety during a vehicle-pedestrian accident. In order to improve the pedestrian protection performance of the new material engine hood, the radial stiffening rib structure and trapezium sandwich structure engine hoods we...

Three equivalence relations are considered on the set of n x n matrices with elements in Fo' an · abelian group with absorbing zero adjoined. They are the relations of diagonal similarity, diagonal equivalence, and restricted diagonal equivalence. These relations are usually considered for matrices with elements in a field, but only multiplication is involved. Thus our formulation in terms of a...
