Constant Propagation Class notes
, 2008 This lecture focuses on the Constant Propagation Analysis. This is just one of many types of analyses that can be applied to programs. We use this example as an incentive for the introduction of the mathematical foundation that will serve us throughout ...

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Law of Shear wave speed in Shear Wave Imaging
工程科学与技术, 2011 : Radiation force from ultrasound has been used to excite monochromatic waves in tissues. The shear wave propagation speed is related to the shear elasticity and shear viscosity of the tissue.

Advanced Engineering Materials, EarlyView.Do not let thermal drift and instrument artifacts deceive high‐temperature nanoindentation results. We compare classical Oliver–Pharr and automatic image recognition analyses across steels and a Ni alloy to quantify these effects. Accounting for artifacts reveals systematic softening with temperature, while Cr and Ni additions boost resistance ...

Propagation Constant of Electric Waves in Plasma forced Static Magnetic Field [PDF]
The propagation of electric waves in plasma has been studied for the propagation of electric waves in the ionosphere. As we want to use the discharge plasma forced a strong magnetic field for the microwave gyrator, isolator and circulator, we considered ...

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying
Advanced Engineering Materials, EarlyView.An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

In Situ Micromechanical Study of Bimodal γ′–γ″ Precipitate Assemblies in Ni–Cr–Al–Nb Superalloy
Advanced Engineering Materials, EarlyView.A Ni–Cr–Al–Nb superalloy with a bimodal γ′–γ″ precipitate distribution is developed. Composite precipitate assemblies form through heterogeneous nucleation, effectively impeding dislocation motion. Micropillar compression reveals high strength at room and elevated temperatures, governed by precipitate shearing, with coupled faulting mechanisms ...

Advanced Engineering Materials, EarlyView.Scandium (Sc)‐doped AlCoCrFeMo HEA coatings are fabricated via flame spraying with 0.1, 0.3, and 0.5 wt% Sc additions. Among these, the HEA‐Sc0.3 coating exhibits the highest corrosion resistance, indicated by a more positive corrosion potential and lower current density.

Constant Propagation Versus Join Reordering
, 2008 1 Introduction Two topics of research in the area of query evaluation for recursive Datalog rules have been constant propagation and join ordering. In the former, given a recursive Datalog program with a constant in the query, the goal is to propagate ...
