This work proposes an extension of the Marching Cubes algorithm, where the goal is to represent implicit functions with higher accuracy using the same grid size. The proposed algorithm displaces the vertices of the cubes iteratively until the stop condition is achieved. After each iteration, the difference between the implicit and the explicit representations is reduced, and when the algorithm ...

Foam problems are about how to best partition spaceinto bubbles of minimal surface area. We investigate thecase where one unit-volume bubble is required to tiled-dimensional space in a periodic fashion according to thestandard, cubical lattice. While a cube requires surface area2d, we construct such a bubble having surface area very closeto that of a sphere; that...

I . Introduction Multi-phase machines offer several key features, such as high reliability, high torque density, and high efficiency . Therefore, they are obtained wide applications from automotive to aerospace [1][2] . One of them is the five-phase PM machine, where the torque density can be improved by injecting third harmonic current . However, in order to maintain high torque density and re...

Absfract-The printed circuit boards (PCB’s) for the 1990’s can be characterized by higher circuit densities, multiple routing layers, newer packaging technologies, and demand for lower manufacturing costs. The task of connecting all the traces on such a complex board will become more and more time consuming. This paper presents the issues involved in the design of a special-purpose processing a...

Strengthening of reinforced concrete structures using FRP has emerged as a potential solution to the problems associated with civil infrastructure. Many researchers have reported significant increases in strength and stiffness of concrete structures strengthened with FRP. Nevertheless, possible brittle failures of the strengthened system due to delamination of the FRP strips and/or sheets could...

A surface-mounted chirped fibre Bragg grating (CFBG) sensor has been used for the first time to monitor delamination growth within a composite material (a transparent, unidirectionally reinforced glass fibre/epoxy resin double-cantilever beam (DCB) specimen). The specimens were tested using a constant displacement rate, with the delamination length being measured using complementary techniques:...
