A film cooling hole is an efficient and reliable method, which widely used in aeroengine turbine blades to effectively improve the thrust–weight ratio of engine. Electrical discharge machining most common manufacturing process for holes. Due rapid quenching after high-temperature melting, a certain thickness recast layer will be formed vicinity wall. The microstructure considered important fact...

Lavy, E. 244 INTRODUCTION Dental disorders as gingivitis, periodontal diseases and calculus formation are prevalent among dogs regardless of their breed, as they are common in human. Gingivitis and periodontitis are prevalent in 82% of dogs aged 6 to 8 years of age and in 96% of dogs aged 12 to 14 years (1, 2). The incidence of dental disorders increases with age (3). Similarly, in humans, the ...

Various design and model selection methods are available for supersaturated designs having more factors than runs but little research is available on their comparison and evaluation. In this paper, simulated experiments are used to evaluate the use of E(s2)-optimal and Bayesian D-optimal designs, and to compare three analysis strategies representing regression, shrinkage and a novel model-avera...
