We present a heuristic approach to the geometric motion-planning problem with the aim to quickly solve intuitively simple problems. It is based on a divide -and-conquer path search strategy, which makes inquiries about feasible paths, an efficient collision detection scheme is developed that handles translations and rotations of polyhedral to compute all times of collision. The whole algorithm ...
We study how some recently proposed noncontextuality tests based on quantum interferometry are affected if the test particles propagate as open systems in presence of a gaussian stochastic background. We show that physical consistency requires the resulting markovian dissipative time-evolution to be completely positive.
Four different force fields are examined for dynamic characteristics using cholesterol as a case study. The extent to which various types of internal degrees of freedom become thermodynamically relevant is evaluated by means of principal component analysis. More complex degrees of freedom (angle bending, dihedral rotations) show a trend towards force field independence. Moreover, charge assignm...
Random vibration analysis of tall structures faces multiple problems due to the large number of elements and high degrees of freedom; that is why this type of analysis is mostly used in simple structures and low degrees of freedom. In the past two decades, changes have been occurred in this type of analysis to be used in complex structures and the large number of elements. Pseudo-Excitation Met...
The well-known electro-mechanical analogy that equates current, voltage, resistance, inductance and capacitance to force, velocity, damping, spring constant and mass has a shortcoming in that mass can only be used to simulate a capacitor which has one terminal connected to ground. A new model that was previously proposed by the authors that combines a mass with a pulley (MP) is shown to simulat...
We compute the critical surface for existence of invariant tori a family Hamiltonian systems with two and three degrees freedom. use compare methods to surfaces: renormalization-group transformations conjugation in configuration space. unveil presence cusps breakup three-dimensional freedom, whereas two-dimensional freedom is expected be smooth.
