Study Design: A prospective, observational case series of eighteen children with early onset scoliosis undergo spine manipulation and casting. Objective: Determine if respiratory system compliance decreases during casting warrants tracheal intubation in all Derotational casting procedures. Background: Children with early onset scoliosis with a Cobb angle greater than 25 degrees will have signif...

Casting metals and alloys makes most of the parts for vehicles. To shorten the time to market and get a satisfied quality new design approach have to be involved. New CAD based technologies are giving an opportunity to make molds faster and cheaper with a high quality than previously using classical methods. In this paper master mold design process including decision about materials is presente...

 Equal suffrage: Given the Dutch electoral system, each voter is permitted to cast one vote per election, which is counted once only in the counting of votes;  Accessibility: Voters must be given every opportunity to participate directly in the election process. If this is not possible, there must be an opportunity to participate indirectly by the granting of a proxy;  Transparency: The elec...

In the renewal of old process computer system of the continuous casting plant, Nippon Steel Corporation has attained cost reduction by the introduction of general-purpose PC server and OS, and middleware (NS SEMI SYSTEM) originally developed in the activity of open system solution. Also the adopting general purpose RDB to the continuous casting plant has been realized in the first time. The red...

In this note we consider the problem of manufacturing a convex polyhedral object via casting. We consider a generalization of the sand casting process where the object is manufactured by gluing together two identical faces of parts cast with a single piece mold. In this model we show that the class of convex polyhedra which can be enclosed between two concentric spheres with the ratio of their ...

Surface quality of the steel slabs in a Continuous Casting (C.C.) process is mainly determined by the stability of the Mold Level Control (MLC). Excessive mold level fluctuations lead to an additional machine scarfing process which is applied to the slabs to avoid surface defects. A conventional Proportional-Integral-Derivative (PID) controller is not robust enough to deal with the disturbances...

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...

Metal casting company produces machinery spare part for manufactures. One of the product produced is dust filter. Most of palm oil mill used this product. Since it is used in most of palm oil mill, company often have problems to address this product. One of problem is the disordered of production process. It carried out by the job sequencing. The important job that should be solved first, least...

introduction: the aim of this study was to evaluate the effect of bridge orientation in casting machine on castability and quality of base metal castings. methods: three groups of patterns with different direction and lengths in casting machine were casted and then studied qualitatively and quantitatively using mean and standard deviation in table of frequency. results: larger nodules and poros...
