Adverse-Mode FFF: Multi-Force Ideal Retention Theory

Impedance Compensation of Flexible Joint Actuator for Ideal Force Mode Control

To realize an ideal force control of robots interacting with humans, a very precise actuation system with zero impedance is desired. A flexible joint actuator may serve for this purpose. This paper presents the design of control algorithms to compensate for the impedance in the flexible joint actuator. To generate the torque as desired, a spring is installed between a motor and a human joint, a...

ideal theory in  -semihyperrings

the concept of  -semihyperring is a generalization of semiring, a generalization of semihyperring and a generalization of      -semiring. since the theory of ideals plays an important role in the theory of  - semihyperring, in this paper, we will make an intensive study of the notions of noetherian, artinian, simple and   regular      -semihyperrings. the bulk of this paper...

Radial Breathing Mode Frequency of Multi-Walled Carbon Nanotube Via Multiple-Elastic Thin Shell Theory

In this paper, the radial breathing mode (RBM) frequencies of multi-walled carbon nanotubes (MWCNTs) are  obtained based on the multiple-elastic thin shell model. For this purpose, MWCNT is considered as a multiple concentric elastic thin cylindrical shells, which are coupled through van der Waals (vdW) forces between two adjacent tubes. Lennard-Jones potential is used to calculate the vdW ...

Retention and Career Force Quality

Previous studies have examined the factors that influence first-term retention. This analysis expands on prior work to investigate the impact of these factors on retention and the quality of personnel retained. We find that the aggregate pay elasticity is approximately 2 (which is similar to that found in earlier analyses), but that this result masks substantial differences in the pay responsiv...
