Concave Diffraction Gratings by High-Precision Injection Moulding
Proceedings, 2019 As an example of the applicable process chain, a concave grating (1175 grooves/mm) with an active area of approx. 24 mm to 24 mm has been replicated by means of electroplating and further by injection moulding with polycarbonate, resulting in a surface ...

Impact of Concave and Convex Solid Surfaces By Liquid-Like Projectiles
Tikrit Journal of Engineering Sciences, 2007 A theoretical and experimental investigation of the normal impact of a flat-ended liquid slug onto ductile cylindrical solid targets is presented. The liquid slug is simulated by wax which is known to behave as a liquid in high speed impact situations ...

Log-concavity and strong log-concavity: A review
Statistics Surveys, 2014 We review and formulate results concerning log-concavity and strong-log-concavity in both discrete and continuous settings. We show how preservation of log-concavity and strongly log-concavity on $\mathbb{R}$ under convolution follows from a fundamental monotonicity result of Efron (1969).
