Progressive refinement rendering of implicit surfaces [PDF]

, 2007
The visualisation of implicit surfaces can be an inefficient task when such surfaces are complex and highly detailed. Visualising a surface by first converting it to a polygon mesh may lead to an excessive polygon count.

Effect of ladle outlet geometry on internal porosity in gravity casting automotive brackets: An experimental investigation [PDF]

China Foundry, 2020
This study investigated whether the pouring ladle's outlet shape could reduce the porosity of aluminum alloy casting products and whether it could be applied to mass production of automotive brackets based on computer simulations and experiment.

Masking Conventional Metallic Cast Post for Enhancing Esthetics

Journal of Contemporary Dentistry, 2016
ABSTRACTLoss of tooth structure occurs due to caries, endodontic treatment, or fracture caused by trauma; restoring these teeth is difficult task for a clinician. Post and core is an option for teeth when excessive tooth structure is lost and teeth need to be restored with crown and bridge procedure.

De-Powdering Effect of Foundry Sand for Cement Casting

Applied Sciences, 2021
With the development of the powder bed 3D printing process, sand casting can be performed with methods that are more advanced than the traditional ones, thus enabling new research on applied materials. When sand is 3D-printed with cement as a binder, its

A progressive refinement approach for the visualisation of implicit surfaces [PDF]

, 2007
Visualising implicit surfaces with the ray casting method is a slow procedure. The design cycle of a new implicit surface is, therefore, fraught with long latency times as a user must wait for the surface to be rendered before being able to decide what ...

Development of a Conventional Fine Grain Casting Process

Superalloys 1984 (Fifth International Symposium), 1984
Integrally cast wheels have been used in small gas turbine engines for many years. As performance requirements have increased, a major design concern has been the improvement of low-cycle fatigue life. Conventional investment castings --which are characterized by coarse, columnar grain structures--have variable, non-predictable fatigue lives ...

Patients’ perspectives on the conventional synthetic cast vs a newly developed open cast for ankle sprains

World Journal of Orthopedics, 2020
Orthopedic physicians typically apply a cast to immobilize a body part that has been injured. There have been no significant structural changes or advances in synthetic casts since the development of the modern cast. The Opencast® is a recently developed type of cast that allows ventilation and direct visual inspection of the skin to avoid cast-related

Casting of aluminum-copper based alloy by controlled diffusion solidification [PDF]

China Foundry, 2015
A quaternary alloy (Al-5.0Cu-0.35Mn-0.25Ti, wt.%), having a similar chemical component with ZL205A, was prepared using a controlled diffusion solidification (CDS) process and a conventional casting process.
