BACKGROUND Although botulinum toxin A is frequently used to augment serial casting in the treatment of soft-tissue contractures in children with cerebral palsy, its effectiveness for this purpose has not been evaluated. The purpose of the present study was to determine whether botulinum toxin A injection increases the efficacy of serial casting. METHODS A prospective, randomized trial was und...

The solidification of metals continues to be a phenomenon of great interest to physicists, metallurgists, casting engineers and software developers. It is a non-linear transient phenomenon, posing a challenge in terms of modelling and analysis. During the solidification of a casting in a mould, the heat-transfer between the casting and the mould plays a vital role. This paper attempts to study ...

A stumbling point for many learning to fly fish is being able to fly cast well enough to ‘present’ a fly to a feeding fish. Even among more skilled fly fishers, learning to fly cast better is often a bottleneck towards advancement in the sport. Fly casting instruction today relies on the visual inspection of the fly casting stroke and the resulting ‘loop’ of fly line. These qualitative visual c...

This paper describes a method to generate Delaunay tetrahedral meshes directly from regular volume data by vertex insertion driven by an error criterion. By adapting the mesh to the input data, the method produces meshes suitable for fast and precise volume ray-casting. A partitioning method that splits the mesh into homogeneous sub-meshes is also presented. Such mesh segmentation strategy turn...

There is a growing need for custom visualization applications to deal with the rising amounts of volume data to be analyzed in fields like medicine, seismology, and meteorology. Visual programming techniques have been used in visualization and other fields to analyze and visualize data in an intuitive manner. However, this additional step of abstraction often results in a performance penalty du...

The dimensionless Niyama criterion was used to predict the formation of microporosity in nickel-based superalloy casting, which extended the model application from a simple plate casting to complex thin-wall superalloy casting. The physical characteristics of the superalloy were calculated by JMatPro software. The relation between the volume percentage of microporosity and the dimensionless Niy...

There are many situations in which mis-coordinated strategic voting can leave strategic voters worse off than they would have been had they not tried to strategize. We analyse the simplest of such scenarios, in which the set of strategic voters all have the same sincere preferences and all cast the same strategic vote, while all other voters vote sincerely. Most mis-coordinations in this framew...

We propose that voting protocols be judged in part on ballot casting assurance, a property which complements universal verifiability. Some protocols already support ballot casting assurance, though the concept has not received adequate explicit emphasis. Ballot casting assurance captures two well known voting concepts – cast as intended, and recorded as cast – into one end-to-end property: Alic...

This work has been motivated by some issues of process monitoring in casting applications. In die casting, as time passes, material is deposited on the inside wall of the die. This foreign material can cause an unacceptable level of porosity in the output of the casting process. After accumulated material reaches a certain level, some of the output of the casting process no longer meets the spe...

Present chemical-physical characteristics of ingot and continuous casting powders can be critically evaluated pointing out history of invention of these materials. In an original tone, pioneering nature of first developments of casting powders will be described, illustrating empirical know-how of casting powders technology, based on trial-and-error method. It will be originally emphasized that ...
