China has had an unprecedented economic boom within the foundry industry in the past two decades. Lost foam casting technology has gained increasing popularity during this time. In China, about two hundred foundries have lost foam casting operations with total annual casting production of approximately 300,000 tons in 2006. This paper reviews the current lost foam casting industry in China with...

The present article deals with a composite casting process that allows to produce bilayer AlSn6-Al strips based on the technique of horizontal continuous casting. In the first part experimental investigations on the production of a single layer AlSn6 strip are described. Afterwards essential results of basic compound casting trials using simple test specimen are presented to define the thermal ...

The presented article explores the impact that the formation of shrinkage cavities has on the heat transfer conditions in a mold. The conditions of heat dissipation have a significant impact on the rate of cooling of different parts of the casting, which in turn affects the microstructure formed in the casting. The results presented in this article should allow the reader to assess how signific...

This work further elaborates on the steel plant MILP production scheduling method presented in Harjunkoski and Grossmann (2001). The proposed improvements include a more flexible model for the casting step, as well as combining orders from consecutive weeks to improve one of the main targets, which is increasing the number of heats per casting sequence. The paper presents a strategy to obtain o...

This work presents an approach to render appropriate shadows with Image Based Lighting in Augmented Reality applications. To approximate the result of environment lighting and shadowing, the system uses a dome of shadow casting light sources. The color of each shadow is determined by the area of the environment behind the casting light source. As a result it is possible that changes in the ligh...

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...
