The anisotropic advantageous properties of fiber reinforced composites may not be fully exploited unless the fibers are properly placed in their optimal spatial orientations. This paper investigates application of Cellular Automata (CA) for curvilinear fiber design of composite laminae for in-plane responses. CA use local rules to update both field and design variables in an iterative scheme ti...

Broadband noise reduction has been investigated by embedding a high-density thin-film decoupling capacitor as much as 1 μF in a laminate package. A complex programmable logic device (CPLD) was mounted on the laminate package instead of bare chip as a noise generating circuits. Then, the package was mounted on an evaluation board. Eight output buffer circuits of the CPLD were simultaneous switch...

An Apollonian configuration of circles is a collection of circles in the plane with disjoint interiors such that the complement of the interiors of the circles consists of curvilinear triangles. One well studied method of forming an Apollonian configuration is to start with three mutually tangent circles and fill a curvilinear triangle with a new circle, then repeat with each newly created curv...

Prosthetic upgrades are specialized prosthetics that enable patients to participate in more demanding recreational activities, such as running. This study examines the use of prosthetic limbs, specifically athletic foot. The current research focused on manufacturing and production properties an samples Foot made from composite materials based a polymethyl methacrylate resin (PMMA) reinforced wi...

Fiberglass boats are one of the options that often used as an alternative to wooden boats. However, leaks on fiberglass very difficult handle at sea, so laminate using a sandwich system material and Polyurethane Foam can be solution deal with where prevent entry water when experiences or cracks in In this study, tests will carried out laminated inserts polyurethane foam variations three types p...

This paper presents a splatting algorithm for volume rendering of curvilinear grids. A stochastic sampling technique called Poisson sphere/ellipsoid sampling is employed to adaptively resample a curvilinear grid with a set of randomly distributed points whose energy support extents are well approximated by spheres and ellipsoids. Filter kernels corresponding to these spheres and ellipsoids are ...

We present the design of a new two degree-of-freedom transmission intended for micro / meso-scale crawling robots which is compatible both with laminate manufacturing techniques and monolithic, “popup” assembly methods. This is enabled through a new design suite called “popupCAD”, a computer-aided design tool which anticipates laminate manufacturing methods with a suite of operations which simp...
