Retrieval of CO Vertical Columns from SCIAMACHY Infrared Nadir Observations

, 2005
Nadir observations in the shortwave infrared channels of SCIAMACHY onboard the ENVISAT satellite can be used to derive infor- mation on CO, CH4, N2O, CO2, and H2O.

Nondestructive Testing of Welded Composite Metal Foams

Advanced Engineering Materials, EarlyView.
X‐ray computed tomography (CT) is used to evaluate welded steel–steel composite metal foam (CMF) joints of two density classes. It reports variation in postweld spatial void distribution and correlates it to weld‐induced changes, mechanical performance, and failure within welded CMF panels.

Radiance Volume: A Caching Technique for Global Illumination

, 2007
本論文中，我們提出一種新的用於全域照明的快取技術—輻射體結構(Radiance Volume)，設法整合現有的快取技術的優勢。我們的目標是在高效能的前提下，為生成的影像加入近似全域照明的現象。我們的演算法能同時支援具有漫射或似鏡面特性的表面上間接照明的計算。同時，藉由把樣本點快取在空間而不是在物體表面上，我們能夠更有效率的處理具有較複雜幾何結構的場景。此外，我們推導出一個支援此快取方式的位移梯度計算，以增加內差的品質。In this thesis, we propose a new caching ...

Influence of Surface Finish on the Tribological Performance of AlTiBN Coatings Deposited on Forming Tools

Advanced Engineering Materials, EarlyView.
Aluminum and nitride coatings are used in industry because they are hard, resist wear, and protect against oxidation. Adding boron can improve friction behavior and other properties. This study tests coatings on surfaces with different finishes. Results show smoother surfaces perform better, while rough ones wear faster, although coatings can reduce ...

Inverse Identification of Energy‐Dependent Laser Absorptivity in NiTi Laser Powder‐Bed Fusion via Calibrated Melt Pool Simulation

Advanced Engineering Materials, EarlyView.
A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.
