Compact 18.5 mm F/2.0 Athermalized Wide-Angle Lens with Low Focus Breathing: Design and Optimization
Applied SciencesDesigning high-speed wide-angle optics for large-format mirrorless cameras presents a fundamental engineering conflict between the short flange back distance and the requirement for high-resolution aberration correction.

Tight Polynomial Bounds for Loop Programs in Polynomial Space [PDF]
Logical Methods in Computer Science, 2021 We consider the following problem: given a program, find tight asymptotic bounds on the values of some variables at the end of the computation (or at any given program point) in terms of its input values.

Tight Polynomial Worst-Case Bounds for Loop Programs [PDF]
Logical Methods in Computer Science, 2020 In 2008, Ben-Amram, Jones and Kristiansen showed that for a simple programming language - representing non-deterministic imperative programs with bounded loops, and arithmetics limited to addition and multiplication - it is possible to decide precisely ...
