In this paper, the forcefree control with independent compensation is described. The forcefree control with independent compensation, in which inertia, friction and gravity torque are compensated independently, can realize flexible motion of robot arms. The forcefree control with independent compensation is compared with other force control methods such as compliance control. Various applicatio...

This paper presents a new method to improve the frequency response of CIC compensation filter. After the CIC filter cascaded the fir filter which has inversed magnitude response to CIC compensation filter was proposed, which improved the pass band and the transition band features of the CIC filter and improved the performance of CIC compensation filter. The decimation factor introduced. It pres...

We present CO J=1-0 observations from the Caltech Millimeter Array of a field in the nearby spiral galaxy M81. We detect emission from three features that are the size of large giant molecular clouds (GMCs) in the Milky Way Galaxy and M31, but are larger than any known in M33 or the SMC. The M81 clouds have diameters ∼ 100 pc and molecular masses ∼ 3 × 10 M . These are the first GMCs to be dete...

To estimate motion, the edges of a moving object can be detected using Active Contours. After detecting the edges throughout the duration of the motion, the contours are registered together in order to obtain the motion model parameters. This idea can be applied to motion artifacts in Magnetic Resonance Images (MRI) which are caused by patient motion during the acquisition of an MRI. Thus, if t...

In this paper we investigate lossless compression schemes for video sequences A simple adaptive prediction scheme is presented that exploits temporal correlations or spectral correlations in addition to spatial correlations It is seen that even with motion compensation schemes that utilize only temporal correlations do not perform signif icantly better than schemes that utilize only spectral co...

Magnetic Resonance Imaging allows for minimally invasive targeting and thermal ablation of tumors while monitoring the temperature distribution. Conventional MR thermometry procedures are hampered by either low accuracy or high sensitivity to motion artifacts due to the use of a reference temperature image. A new, dual-echo technique has been developed to obtain the temperature distribution wit...

Motion estimation plays an important role in video coding schemes by removing temporal redundancies that exist in image sequences. Motion information that is required in motion compensated prediction is transmitted as side information, as in forward motion estimation, or can be computed at the receiver in backward motion estimation. The former method has the advantage of more accurate predictio...

Public and private sector activities often bring about undesired income-distributional effects, and these give rise to considerations of ways to compensate the losers. When "lump-sum" compensation is not possible, "second-best" compensation arrangements need to be identified and evaluated. The term "compensation" is often used to mean explicit payments from those who gain from a policy change, ...

The national health care reform debate raises important issues about the effect of federal legislation restructuring health care delivery on state workers' compensation systems. Workers' compensation is the oldest and most successful no-fault insurance system in the country, providing comprehensive medical benefits as well as cash income support, rehabilitation, and burial benefits for work-rel...

Temperature compensation of circadian clocks is an unsolved problem with relevance to the general phenomenon of biological compensation. We identify casein kinase 2 (CK2) as a key regulator of temperature compensation of the Neurospora clock by determining that two long-standing clock mutants, chrono and period-3, displaying distinctive alterations in compensation encode the beta1 and alpha sub...
