In metal machining, regenerative chatter seriously affects tool life, part surface quality and cutting efficiency. To suppress generated during milling, researchers have proposed a variable spindle speed technique. But the previous VSS milling model is based on two degrees of freedom system (two-DOF). this paper, three-DOF suitable for thin-walled parts by introducing axial contact angle. The i...

Background and Objectives: Constant monitoring of healthcare organizations’ performance is an integral part of informed health policy-making. Several hospital performance assessment methods have been proposed in the literature. Pabon Lasso Model offers a fast and convenient method for comparative evaluation of hospital performance. This study aimed to evaluate the relative performance of hospit...

The elastic organ spanning the propodite-dactylopodite (PD) joint in the leg of the crab Carcinus maenas was first described by Burke (1954) and shown by him to have mechanoreceptive function. Text-fig. I is a diagram of the organ in situ showing its relation to the surrounding structures. The nerve cells of the organ are bipolar neurons, with ovoid somata, proximal running axons, and long dist...

An enhanced unfolding Inverse Finite Element Method (IFEM) has been used together with an extended strain-based forming limit diagram (EFLD) to develop a fast and reliable approach to predict the feasibility of the deep drawing process of a part and determining where the failure or defects can occur. In the developed unfolding IFEM, the meshed part is properly fold out on the flat sheet and tre...

We present an accurate algorithm to compute the internal Voronoi diagram and medial axis of a 3-D polyhedron. It uses exact arithmetic and exact representations for accurate computation of the medial axis. The algorithm works by recursively finding neighboring junctions along the seam curves. To speed up the computation, we have designed specialized algorithms for fast computation with algebrai...

We propose an approach to audio-based data-driven music visualization and an experimental design to study if the music visualization can aid listeners in identifying the structure of music. A three stage system is presented including feature extraction, the generation of a recurrence plot and the creation of an arc diagram to visualize the repetitions within a piece. Then subjects are asked to ...
