Recent advances in the evaluation of the amputation stump, the materials that are available for prosthetic application, techniques of improving socket fit, and prosthetic finishings promise to dramatically improve amputee function. Precision casting techniques for providing optimal fit of the amputation stump using materials such as alginate are described. The advantages of transparent check so...

A validation study in order to evaluate the efficiency of the inductively coupled plasma optical emission spectrometry (ICP-OES) in the analysis of minor elements (Manganese, Chromium, Copper, Iron and Titanium) in aluminium alloys was carried out. Aluminium casting samples were obtained from addition to aluminium baths of compressed powder compacts of each alloying element and aluminium (minit...

Heat transfer in the mold is the heart of the continuous casting process and its quantitative analysis was pioneered by Keith Brimacombe. With many different processes currently competing, it is appropriate to apply modeling to investigate the theoretical limits of continuous casting speed and productivity. The heat transfer rate during solidification processes drops with time so the shell thic...

High-resolution simulations often rely on the Adaptive Mesh Resolution (AMR) technique to optimize memory consumption versus attainable precision. While this technique allows for dramatic improvements in terms of computing performance, the analysis and visualization of its data outputs remain challenging. The lack of effective volume renderers for the octree-based AMR used by the RAMSES simulat...

We harvest training images for visual object recognition by casting it as an IR task. In contrast to previous work, we concentrate on fine-grained object categories, such as the large number of particular animal subspecies, for which manual annotation is expensive. We use ‘visual descriptions’ from nature guides as a novel augmentation to the well-known use of category names. We use these descr...

In this work we present an acceleration technique for direct volume rendering, that is based on a preprocessing step. This transforms the original uniform grid into an adaptively reduced tetrahedral grid. The basic idea is to exploit the inherent adaptivity information of the reduced grid for the ray integration with importance sampling. An integration step is always performed from cell face to...

ÐSeveral e€ective acceleration techniques for volume rendering o€er ecient means to skip over empty space, providing signi®cant speedup without a€ecting image quality. The e€ectiveness of such an approach depends on its ability to accurately estimate the object boundary inside a volume with minimal computational overhead. We propose a novel boundary cell-based acceleration technique for ray ca...

Objectives There is a short period during rapid growth when a scoliosis brace is most effective. In standard practice, the inbrace correction is not measured during brace casting. The first assessment of the in-brace correction in the follow-up clinic may trigger brace adjustment for improved spinal alignment resulting in delay of effective treatment and increased number of radiographs. The obj...

OBJECTIVE To identify the effect of serial casting combined with Botulinum toxin type A (BTX-A) injection on spastic equinus foot. METHOD Twenty-nine children with cerebral palsy who had equinus foot were recruited from the outpatient clinic of Rehabilitation Medicine. The children were divided into 2 groups, one of which received serial casting after BTX-A injection, and the other which only...

The problem of voids and porosity has long plagued the dental technician. Many times an otherwise acceptable casting has had to be discarded because voids or porosities have developed within the casting. Because of numerous variables a technician often does not know the cause of the casting failure. Many investigators have studied variables that may affect the occurrence of voids and porosities...
