Riser sleeves are an effective tool in the steel foundry industry for minimizing riser size and increasing casting yield. Reliable simulation of the performance of riser sleeves requires accurate temperature dependent thermophysical properties. Unfortunately there is little or no such property data available in the open literature. A limited number of sleeve manufacturers provide advice and pro...

Many graphical objects can be represented by swept volumes (including its subset – generalised cylinders) by sweeping 2D or 3D templates along 3D trajectories. In this paper, we present a new approach for constructing swept volumes using image templates. We utilise scalar fields as our underlying data type, and employ volume ray casting techniques for rendering swept volumes in their original s...

BACKGROUND Exposure to polycyclic aromatic hydrocarbons (PAHs) has been reported in several industries, including those of the aluminum production, coal gasification, coke production, iron and steel foundries, coal tar and related products, carbon black and carbon electrodes production. PATIENTS AND METHODS This paper reviews the results from cohort studies conducted on workers exposed to PAH...

OBJECTIVE To study the impact of occupational silica exposure on the incidence rates of sarcoidosis and rheumatoid arthritis (RA) in a cohort of exposed workers in Swedish iron foundries. DESIGN The prevalence of sarcoidosis and RA in a cohort of silica exposed workers was compared with the prevalence in the general Swedish population in this register study. A mixed model was used to calculat...

Interactive high quality volume rendering is becoming increasingly more important as the amount of more complex volumetric data steadily grows. While a number of volumetric rendering techniques have been widely used, ray casting has been recognized as an effective approach for generating high quality visualization. However, for most users, the use of ray casting has been limited to datasets tha...
