The conceptual design of parallel robots can be dated back to the time when Gough established the basic principles of a device with a closed-loop kinematic structure (Gough 1956), that can generate specified position and orientation of a moving platform so as to test tire wear and tear. Based on this principle, Stewart designed a platform for use as an aircraft simulator in 1965 (Stewart 1965)....

Abstract The classical uncertainty principles deal with functions on abelian groups. In this paper, we discuss the uncertainty principles for finite index subfactors which include the cases for finite groups and finite dimensional Kac algebras. We prove the Hausdorff-Young inequality, Young’s inequality, the Hirschman-Beckner uncertainty principle, the Donoho-Stark uncertainty principle. We cha...

We show that the model-calibration estimator for the finite population mean, which was proposed by Wu & Sitter (2001) through an intuitive argument, is optimal among a class of calibration estimators. We also present optimal calibration estimators for the finite population distribution function, the population variance, the variance of a linear estimator and other quadratic finite population fu...

Symmetrically dividing neuroepithelial cells may produce two daughters that are both proliferating or both postmitotic, as highlighted by Zigman et al. in this issue of Neuron and Sanada and Tsai in a recent issue of Cell. Here, I will attempt to offer a simple explanation why these results may be so different.

Abstract In the present investigation, laminated composite beams subjected to a bending static loading are studied in order determine their failure mechanisms and first ply (FPF) load. The FPF analysis is performed using refined rectangular plate element. element formulated based on classical lamination theory (CLT) calculate in-plane stresses. To achieve this goal, several criterions, includin...

The stego image quality produced by the histogram-shifting based reversible data hiding technique is high; however, it often suffers from lower embedding capacity compared to other types of reversible data hiding techniques.
