... reverse bias. In this paper, we report the fabrication of ZnO UV sensor consisting of ZnO micro spheres in a matrix of nanowires. Experimental ZnO sheets consisting of spheres in nanowires were synthesized ... of gas kinetics in controlling the shapes are underway and can be found elsewhere (S. S. Hullavarad and P.C. Karulkar, under preparation). Mo et al. [27] h...

... filters is called a color filter ar- ray (CFA). In the Bayer pattern [1], a popular CFA pattern, the sensor produces a two-dimensional array in which each spatial location contains only a red (R), ... color differences are constant within a region. The iteration is based on thresholding the variance of the change for each channel. If the variance is larger than a cer- tain...

... training of arbitrary walking situations, hence not only the simulation of floor walking but also for example of stair climbing and perturbations. Conclusion: Locomotor therapy is a fascinating ... training of walking on even ground. In contrast to all treadmill bound machines, it enables the patient to train arbitrary gait trajectories and daily life walking situations. It is a...
