This paper describes a new approach for precise image shift detection between two images. The approach is based on an analysis of the phase difference spectrum between two images. Image shifts are directly evaluated from the phase difference spectrum without Fourier inversion. The cross s~ectrum is utilized as the weight parameter distribution. Synthetic and real images of typical image pattern...

The impact-based grain flow sensor is widely used in the combine harvester yield monitor systems to measure the crop yield .but its accuracy wrecked by false signal of excessive natural vibration. A step response experiment was carried to identify the math function of the sensor. Experiment found that the math function of the sensor was a second-order vibration system, its Damping Ratio was 0.0...

In this paper the sequential prediction problem with expert advice is considered for the case where losses of experts suffered at each step cannot be bounded in advance. We present some modification of Kalai and Vempala algorithm of following the perturbed leader where weights depend on past losses of the experts. New notions of a volume and a scaled fluctuation of a game are introduced. We pre...

Using low energy electron microscopy we observe that Pd deposited on Ru only attaches to small sections of the atomic step edges surrounding Pd islands. This causes a novel epitaxial growth mode in which islands advance in a snakelike motion, giving rise to labyrinthine patterns. Based on density functional theory together with scanning tunneling microscopy and low energy electron microscopy we...

In this paper, we propose a two-step framework to advance our knowledge of how to identify and evaluate opportunities presented by emerging information technologies (IT). As a first step, we match the features and limits of the IT innovation with the requirements of the application areas in question, typically on the business process level. As a second step, we sketch out guidelines to evaluate...

The first objective in any financial organization is to improve performance, and performance evaluation also is one of the best ways to advance operations in organizations. By utilizing different methods of performance evaluation, organizations can evaluate the effectiveness and efficiency of processes that are in accord with strategic objectives. In addition, the performance evaluation instrum...
