We propose a method for fitting a piecewise parametric curve to a sequence of digitized points such as those acquired from a computer mouse or digitizing pen. The fitting is done on-the-fly rather than after a complete sequence of points has been acquired, thereby providing high quality parameterized curves for immediate display during drawing. The method is fast, accurate, and robust, handles ...

apricot is climacteric and its ripening process is regulated by ethylene, therefore, inhibiting ethylene biosynthesis or action should slow the ripening process. this study was conducted to decrease materials losses and increase storage life of fruit by proper packaging. different packaging (polyethylene film, polyethylene film with ethylene absorbent, shrink pack and control) were used. after ...

Synthetic Aperture Radar (SAR) Interferometry (InSAR), using data from the European Space Agency satellites ERS1 and ERS2, is being used to image, survey and map surface movement of the London region. Local and regional movement due to shrink and swell of the London Clay geology, tunnelling, and possibly ground water abstraction has been investigated here for the first time by InSAR. Cyclic ann...

COMPUTATIONAL ENGINEERING AND DESIGN CENTER SCHOOL OF ENGINEERING SCIENCES Doctor of Philosophy Artificial Intelligence Technologies in Complex Engineering Design by Yew Soon Ong Engineering design optimization is an emerging technology whose application both tends to shorten design-cycle time and finds new designs that are not only feasible, but also nearer to optimum, based on specified desig...

Noise will be unavoidable during image acquisition process and denosing is an essential step to improve the image quality. Image denoising involves the manipulation of the image data to produce a visually high quality image. Finding efficient image denoising methods is still valid challenge in image processing. Wavelet denoising attempts to remove the noise present in the imagery while preservi...

Robust parameter design (RPD) is considered as a cost effective tool for reducing process variability. Robust parameter control, integrating RPD with automatic process control, will performance better than the traditional RPD approach. This paper proposed a strategy of robust process control based on selecting online controllable variables with consideration of generalized quality cost, which i...
