The Mechanism of Seasonal Variation in Sea Surface Height in the Bohai Sea

Earth and Space Science
AbstractThe Bohai Sea, located at the edge of western Pacific, is one of the most vulnerable regions under climate change. Using the high‐precision MIKE three‐dimensional hydrodynamic numerical model, this study conducted comparative experiments to investigate the impacts of atmospheric pressure, wind, specific volume, and evaporation precipitation and

Performance Analysis of Abradable Coating Systems for Aircraft Gas Turbines

Advanced Engineering Materials, EarlyView.
Three CoNiCrAlY/YSZ/MgAl2O4 abradable liner configurations on a nickel‐superalloy are evaluated by thermal‐gradient cycling and incursion tests. Laser ablation of the bondcoat and/or Y2O3‐stabilized ZrO2 (YSZ) intermediate layer increases mechanical interlocking and bonding for thick topcoats.

Is the exchange between the Black Sea and the Mediterranean changing over time?

Environmental Research Communications
The Black Sea Waters (BSW) that are exported into the Aegean Sea largely control its overturning circulation, as well as its regional biogeochemical characteristics.

Applying Parametric Model Correction on Sea State Bias to Estimate Sea Surface Height over the Savu Sea [PDF]

BIO Web of Conferences
Range, the distance between the satellite and the ocean surface covered by the radar trace, is measured by tracking the received waveform. The range measurement errors may be caused by sea state bias (SSB) which is the main source of measurement errors ...

Affecting the Properties of Copper–Graphene Electroconductive Composite by Severe Plastic Deformation

Advanced Engineering Materials, EarlyView.
Copper‐based composites enhanced with carbon feature convenient mechanical properties and favorable electric conductivity. Processing via deformation and thermomechanical treatments can introduce advantageous microstructures further enhancing their performance. Herein, copper–graphene powder‐based composites are directly consolidated via rotary swaging

Interannual variability of sea surface height anomaly in the South China Sea

Journal of Physics: Conference Series, 2019
Abstract Spatial variability of Sea Surface Height Anomaly (herein after SSHA) in the South China Sea was investigated through the response of sea surface to interannual phenomenon. In this research, satellite altimetry data were used which covered periods from 1992 to 2015. Signal analysis was performed to separate dominant spectrum for

Understanding the Stochastic Nature of Process Parameter Development of Blown Powder Laser Beam Directed Energy Deposition Additive Manufacturing of Pure Molybdenum

Advanced Engineering Materials, EarlyView.
Identified through the use of statistical design of experiments and metallographic investigation, this study exposes the stochastic origins of intergranular cracks in blown powder laser beam directed energy deposition additive manufacturing of pure molybdenum. It further demonstrates a successful crack mitigation approach with direct correlation to the

Robust Spot Melting by 3D Spot Arrangements in Electron Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
This work proposes an approach to replace separately melted contours for spot melting in electron beam powder fusion. Adapting the spot arrangements close to the contour combined with stacking yields a comparable surface quality without the inherent challenges of separate contours, as demonstrated, by electron optical images and roughness measurements.

Slope Correction for Ocean SAR Altimetry

Earth and Space Science
Since the 2010 launch of Cryosat‐2, a new generation of altimeters, referred to as SAR altimetry, has emerged and partially replaced the previous conventional altimeters known as Low Resolution Mode (LRM) altimetry.

Microstructure‐Controlled Crack Propagation and Fracture Resistance in MoSiBTiC Alloy Revealed by Multiscale Extended Finite Element Method Modeling

Advanced Engineering Materials, EarlyView.
A two‐dimensional multiscale finite element analysis framework was established for the first‐generation MoSiBTiC alloy, and the mechanical and fracture‐related parameters of the constituent phases were calibrated through experiments and simulations. The framework provides a basis for analyzing crack propagation behavior in its complex microstructure ...
