Effects of attack angle on performance of actively controlled high-rise building motion
, 2010 Wind loading on high-rise buildings is complicated in nature, especially when across-wind motion caused by the vortex shedding effect is considered. Hence, wind tunnel tests serve as a reliable alternative for research on wind-induced vibration.

Advanced Engineering Materials, EarlyView.Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.

Hyperglycemia induced bilateral acute attack of angle closure in a young patient
Indian Journal of Ophthalmology. Case ReportsAn acute attack of angle closure is infrequent in young individuals, and the etiologies are different from those seen in adults. Hyperglycemia, in the setting of uncontrolled diabetes, can precipitate an acute attack of angle closure due to increased ...

Numerical investigations on the sabots discard process of an APFSDS at different angles of attack
The Journal of Engineering, 2018 Sabot asymmetric discard after the projectile being launched from the muzzle at various angles of attack and 4Ma is investigated. This is implemented by the coupling computational fluid dynamics (CFD) and six degrees-of-freedom exterior ballistic code ...

Time‐Dependent Oxidation and Scale Evolution of a Wrought Co/Ni‐Based Superalloy
Advanced Engineering Materials, EarlyView.This study shows how a new wrought Co/Ni‐based superalloy resists oxidation at 800 ∘$^\circ$C. The oxide scale changes from rough, fast‐growing spinel to a dense, protective chromia–alumina layer. Atom probe analysis reveals tiny refractory‐rich bubbles at the interface that mark the transition to long‐term, diffusion‐controlled protection ...

Angle of Attack Control for Running Robots
, 2011 For running robots, angle of attack control is an important part of the controller, as the angle of attack has a large influence on the state of the running robot. Over the last 25 years, many angle of attack controllers have been introduced. However, it
