Superpostion of Waves

, 2001
The above simulations show disturbances on two identical strings (position is in centimeters and time is in seconds). Simulation 1 shows two Gaussian-shaped waves of identical amplitude and width, Simulation two shows two Gaussian-shaped waves of equal ...

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.

Enhanced Strength and Corrosion Resistance of Ti‐13Nb‐12Ta‐10Zr‐4Sn Alloy by Aging Treatment

Advanced Engineering Materials, EarlyView.
This work systematically investigates the effect of aging treatment on mechanical properties and corrosion behavior of vacuum arc‐melted Ti‐13Nb‐12Ta‐10Zr‐4Sn alloy. Owing to the increased α″ martensite, strength and corrosion resistance were significantly enhanced by aging treatment.

Demo 09-15 Longitudinal Slinky Waves

, 2001
Rapidly compressing a section of a suspended Slinky spring and releasing it creates a "compression" which propagates along the spring, as shown in Figure 1. Both compressions and rarefactions are illustrated on the video.

Electrochemical Behavior of Flame‐Sprayed Sc‐Doped AlCoCrFeMo High‐Entropy Alloy Coatings in 3.5% Sodium Chloride Solution

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.

Waves Problem: Superposition

, 2001
The above simulation shows how two waves can add together to produce a standing wave on a string (position is in centimeters and time is in seconds). The third panel represents the string.

Instability in internal solitary waves with trapped cores

, 2012
A numerical method that employs a combination of contour advection and pseudo-spectral techniques is used to investigate instability in internal solitary waves with trapped cores. A three-layer configuration for the background stratification in which the
