Finite-Horizon Robustness Analysis under Mixed Disturbances using Signal-IQCs
Frederik Thiele, Harald Pfifer, Felix Biertümpfel
Common worst-case analyses for uncertain finite-horizon systems consider quadratic performance metrics based on the strict Bounded Real Lemma. Thus, they assess system performance…

A Surprising Periodicity Detected During a Super-outburst of V844 Herculis by TESS
A. Greiveldinger, P. Garnavich, C. Littlefield +6
We identify a previously undetected periodicity at a frequency of 49.080.01 d (period of 29.340.01 minutes) during a super-outburst of V844 Her observed by TESS. V…
