A data-driven approach to UIO-based fault diagnosis
In this paper we propose a data-driven approach to the design of a residual generator, based on a dead-beat unknown-input observer, for linear time-invariant discrete-time state-space models, whose state equation is affected both by disturbances and by actuator faults. We first review the modelbased conditions for the existence of such a residual generator, and then prove that under suitable assumptions on the collected historical data, we are both able to determine if the problem is solvable a…

Love how developers and customers pay Apple money to make the App Store really well vetted.

Pirated Movie App Disguised as Vision Test Snuck Onto App Store
A vision testing app named "Kimi" with a not-so-hidden pirated movie feature recently made its way past Apple's review team, ultimately...

Positron Acceleration in Plasma Wakefields
Plasma acceleration has emerged as a promising technology for future particle accelerators, particularly linear colliders. Significant progress has been made in recent decades toward high-efficiency and high-quality acceleration of electrons in plasmas. However, this progress does not generalize to acceleration of positrons, as plasmas are inherently charge asymmetric. Here, we present a comprehensive review of historical and current efforts to accelerate positrons using plasma wakefields. Prop…

Society when the hundredth study shows that UBI pretty much instantly leads to a better life for literally everyone: 🤷
Society when fintech douchebros say prime numbers and bad pictures of apes are the future of the economy: "Of course it is. Here's billions of dollars. Also, do you want a back rub?"
