This project proposes an obstacle avoiding path planning algorithm based on cell decomposition method for a car-like robot. Dijkstra’s algorithm is applied in order to find the shortest path. Using cell decomposition, the free space of the robot is exactly partitioned into cells. Then, the connectivity graph is created followed by calculating the shortest path by Dijkstra’s algorithm. This proj...

Where a 2D problem of optimal profile in variable speed flow is resolved in a class of convex Bezier curves, using symbolic and numerical computations.

A new interfacing method is presented to control mobile robot(s) in a supervised manner. Mobile robots often provide global position information to an operator. This research describes a method whereby the operator controls a mobile robot(s) using his finger or stylus via a touchpad or touchscreen interface. Using a mapping between the robot’s operational site and the input device, a human user...

The human hard palate shows between-subject variation that is known to influence articulatory strategies. In order to link such variation to human speech, we are conducting a cross-sectional MRI study on multiple populations. A model based on Bezier curves using only three parameters was fitted to hard palate MRI tracings using evolutionary computation. The fits produced consistently yield high...

The distance between a Be-....ier segment and its control polygon is bounded in terms of the second differences of the control point sequence and a constant that depends only on the degree of the polynomial. The constant derived here is the smallest possible and is sharp for the Hausdorff distance between control polygon and curve segment. The bound provides a straightforward proof of quadratic...

Passive path tracking training is usually used for robot assisted lower limb rehabilitation. The movement of will cause the fluctuation joint force. This letter presents an optimal planning algorithm to reduce patient's force caused by a moveable multifunction rehabilitation during passive pedaling training. dynamics model human-robot system established, and forces patient are analysed. process...

This paper deals with the isogeometric analysis using B-splines of space rods subject to Kirchhoff-Love hypotheses. A multi-patch isogeometric approach for the numerical analysis of the three-dimensional Kirchhoff-Love rod theory is developed. We use Bezier and B-splines interpolations and we show that they are able to attain very good accuracy for rod structures, particularly for developing a ...

With the 3G development, more and more rich media applications appear on mobile devices. The efficiency of scalable vector graphics player is very crucial for constrained mobile devices. In this paper, we propose a partial rendering algorithm which dynamically traces the invalid areas of elements in the scene and rationally divides the scene into several partial rendering areas. Compared with t...
