The purpose of this literature review is to critique training studies that have examined the effects jump-landing programmes on bone health parameters in premenopausal women. Activities such as jumping and hopping been proposed achieve desired unusual or atypical strain distributions skeleton for women who are habitually inactive not involved high-impact sports, however specific protocols optim...

Time-hopping (TH) communication techniques have gathered increasing attention since the introduction of ultra-wide-band impulse-radio, by Scholtz, in 1993. In these systems, the design of TH sequences is a critical point, since they constitute the only source of diversity that protects the transmitted signal from the interference caused by multipath and by the presence of other users. Moreover,...

In this paper, the issue of control of impact forces generated during the interaction between the hopping robot toe and the ground during landing has been considered. The force thus generated can damage the robot altogether. With the objective to control these impact forces impedance control strategy has been applied to the hopping robot system. The dynamics pertaining to the impact between rob...

For branched polymers, the curvilinear motion of the branch point along the backbone is a significant relaxation source but details of this motion have not been well understood. This study conducts multi-chain sliplink simulations to examine effects of the spatial fluctuation and curvilinear hopping of the branch point on the viscoelastic relaxation. The simulation is based on the primitive cha...

A family of four weakly coupled electronically nonadiabatic bimolecular model photochemical systems is presented. Fully converged quantum mechanical calculations with up to 25 269 basis functions were performed for full-dimensional atom–diatom collisions to determine the accurate scattering dynamics for each of the four systems. The quantum mechanical probabilities for electronically nonadiabat...

To speed up the convergence of reinforcement learning (RL) algorithms by more efficient use of computer simulations, three algorithmic techniques are proposed: Time Manipulation, Time Hopping, and Eligibility Propagation. They are evaluated on various robot control tasks. The proposed Time Manipulation [1] is a concept of manipulating the time inside a simulation and using it as a tool to speed...

Anti-jamming capability and protection against undesired interception are key priorities in ad hoc networks for secure applications. These features are supported by spread spectrum (SS) techniques such as frequency hopping (FH). In a frequency hopping ad hoc network, the phase of the hopping sequence is typically derived from the local time reference (clock reading) of each node. Therefore, net...

In human and animal motor control several sensory organs contribute to a network of sensory pathways modulating the motion depending on the task and the phase of execution to generate daily motor tasks such as locomotion. To better understand the individual and joint contribution of reflex pathways in locomotor tasks, we developed a neuromuscular model that describes hopping movements. In this ...
