In this paper, a new robust feedback controller for trajectory control of n-link robot manipulators with parametric uncertainties is suggested. The proposed controller using dynamic compensation scheme leads to improvement in transient response while achieving asymptotic regulation in the presence of parametric uncertainties. The ultimate uniform(More)
In this paper, we design an image-based robust controller to compensate uncertainties with image Jacobian and robot dynamics due to uncertain depth measurement and load variations. The proposed controller with eye-in-hand structure has separate terms to compensate each of uncertainties. The ultimately uniform boundedness of the closed-loop system is proved(More)
In this paper, a new robust feedback controller for trajectory control of n-link robot manipulators under parametric uncertainties is suggested. The proposed controller using dynamic compensation scheme leads to improvement in the transient response and fast convergence of tracking error to a neighborhood of zero in the steady-state. The uniformly ultimate(More)
We study the distribution function of the b–quark for inclusive semileptonic B decays in the framework of the parton model. We compare the functional behavior of the fragmentation inspired function and the Gaussian ACCMM function, and discuss their validity. Using the HQET parameters, we can critically test these models.

The neutral Higgs pair production at the LHC is studied in the MSSM, the large extra dimensional (ADD) model and the Randall-Sundrum (RS) model, where the total cross section can be significantly enhanced compared to that in the SM. The p T , invariant mass and rapidity distributions of each model have been shown to be distinctive: The ADD model raises the(More)
We investigate the form factors for exclusive semileptonic decays of B-meson to D, D∗, based on the parton picture and helped by the results of the HQET. We obtain the numerical results for the slope of the Isgur-Wise function, which is consistent with the experimental results, and we extracte the dependences of hadronic form factors on q by varying input(More)
We developed the new parton model approach for exclusive semileptonic decays of B-meson to D, D by extending the inclusive parton model, and by combining with the results of the HQET, motivated by Drell-Yan process. Without the nearest pole dominance ansätze, we derived the dependences of hadronic form factors on q2. We also calculated numerically the slope(More)
