In current casting factories, tilting type automatic pouring machines are often used to pour the molten metal into the mold, with the operator relying on experience, perception and repeated testing to manually determine the pouring velocity. However, seeking an optimum multistep pouring velocity through trial and error results in an enormous number of combinations and is very difficult. For thi...
Background & Aims: The goal of this study was to determine the effect of foot serial casting along with botulinum toxin type-A injection on spasticity in children with cerebral palsy. Methods: This study was a randomized clinical trial performed as a pre-post, double blind study. It was performed on 25 children with hemiplegia and diplegia (2-8 years) in Tehran city, who were referred to valias...
Intoduction: Neuropathic plantar ulceration is one of the serious handicap to the patient with anaesthetic feet in active life. The only way to heal a plantar ulcer is to provide rest it. If the patient walks on the ulcer,it spreads and osteomyelitis ensues; the scarring and distortion make further inevitable ulceration until walking finally becomes impossible.Neuropathic trophic plantar ulcera...
BACKGROUND The therapeutic efficacy of serial casting on idiopathic scoliosis has been gradually documented. However, literatures on serial casting for congenital scoliosis (CS) remain extremely rare. This paper aimed to compare the treatment outcomes of serial casting between CS and non-CS patients to comprehensively evaluate the therapeutic characteristics of serial casting on CS patients. ...
We propose a simple modi cation to the classical polygon rasterization pipeline that enables exact, e cient raycasting of bounded implicit surfaces without the use of a global spatial data structure or bounding hierarchy. Our algorithm requires two descriptions for each object: a (possibly non-convex) polyhedral bounding volume, and an implicit equation (including, optionally, a number of clipp...
The continuous roll casting process (CRC), consisting of continuous strip casting between rolls, is now well known. It was introduced by the SCAL Company (Pechiney Ugine Kuhlmann Group) 60 years ago 1 . The process consists of solidifying aluminum or aluminum alloys between the water-cooled rolls of a duo rolling mill. From the moment when solidification is completed to the moment when the stri...
In the paper the analysis of wax pattern and casting dimensions changes during each stages of investment casting technology process has been presented. Results of wax patterns and castings of test plate free and restrained contractions dimensions changes research carried out in Department of Foundry Engineering at Brno University of Technology have been presented as well. Moreover obtained resu...

Unfortunately, many things can go wrong. In the United States voters are often confronted with bewildering numbers of issues to decide. Ballot choices and designs vary from election to election and from district to district—or even within a district. People may have trouble casting the votes they intend. Both machine and human issues affect how votes are recorded and counted. Especially in a cl...
