Sensitivity Analysis for Piecewise-Affine Approximations of Nonlinear Programs with Polytopic Constraints
Nonlinear Programs (NLPs) are prevalent in optimization-based control of nonlinear systems. Solving general NLPs is computationally expensive, necessitating the development of fast hardware or tractable suboptimal approximations. This paper investigates the sensitivity of the solutions of NLPs with polytopic constraints when the nonlinear continuous objective function is approximated by a PieceWise-Affine (PWA) counterpart. By leveraging perturbation analysis using a convex modulus, we derive g…

Automated Data Visualization from Natural Language via Large Language Models: An Exploratory Study
The Natural Language to Visualization (NL2Vis) task aims to transform natural-language descriptions into visual representations for a grounded table, enabling users to gain insights from vast amounts of data. Recently, many deep learning-based approaches have been developed for NL2Vis. Despite the considerable efforts made by these approaches, challenges persist in visualizing data sourced from unseen databases or spanning multiple tables. Taking inspiration from the remarkable generation capab…

The US supreme court heard one of the most sadistic, extreme anti-abortion cases yet
What is really at stake is not the law
– which, like all federal laws, is now subject to the distortion or selective nullification of the court, according to the conservative majority’s whims.
What was really at stake was the status of American women,
who now have to beg before the courts not to face legally enforced medical negligence that will kill and maim them.
And what …

Drohnen treffen russisches Stahlwerk
Ukrainische Drohnen haben in der Nacht ein großes russisches Stahlwerk in der Region Lipezk angegriffen und beschädigt. Das berichtet die Nachrichtenagentur Reuters unter Berufung auf eine Quelle des Kiewer Geheimdienstes. Demnach zerstörte der Angriff eine Sauerstoffstation im Nowolipezker Hüttenwerk teilweise, was langfristige Auswirkungen auf die Arbeit des Unternehmens haben werde.

Low-cost adaptive obstacle avoidance trajectory control for express delivery drone
This paper studies quadcopters obstacle avoidance trajectory control (OATC) problem for express delivery. A new nonlinear adaptive learning controller that is low-cost and portable to different wheelbase sizes is proposed to adapt to large-angle maneuvers and load changes in UAV delivery missions. The controller consists of a nonlinear variable gain (NLVG) function and an extreme value search (ES) algorithm to reduce overshoot and settling time. Finally, simulations were conducted on a quadcopt…
