techniques are examined to overcome the performance degradation caused by the channel dispersion using slow frequency hopping (SFH) with dynamic frequency hopping (DFH) pattern adaptation. In DFH systems, the frequency slots are selected by continuous quality monitoring of all frequencies available in a system and modification of hopping patterns for each individual link based on replacing slot...

Performance degradation caused by channel dispersion can be mitigated using avoidance techniques such as frequency hopping spread spectrum. Adaptive frequency hopping techniques such as matched frequency hopping (MFH), clipped matched frequency hopping (CMFH) and advanced frequency hopping (AFH) have been introduced as efficient techniques in slowly fading dispersive channels. These techniques ...

Abstract Cuprates with corner-sharing CuO 4 plaquettes have received much attention owing to the discoveries of high-temperature superconductivity and exotic states where spin charge or orbital degrees freedom are separated. In these systems spins strongly coupled antiferromagnetically via superexchange mechanisms, high nearest-neighbour coupling varying among different compounds. The electroni...

This paper proposes an evolutionary optimization approach for optimal hopping of humanoid robots. In the proposed approach, the hopping trajectory is generated by a central pattern generator (CPG). The CPG is one of the biologically inspired approaches, and it generates rhythmic signals by using neural oscillators. During the hopping motion, the disturbance caused by the ground reaction forces ...

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...
