Triangulated surfaces in triangulated categories [PDF]
Journal of the European Mathematical Society, 2018 For a triangulated category \mathcal A with a 2-periodic dg-enhancement and a triangulated oriented marked surface S , we introduce a dg-category

Advanced Robotics Research, EarlyView.Visual teach‐and‐repeat (VTR) navigation allows robots to learn and follow routes without building a full metric map. We show that navigation accuracy for VTR can be improved by integrating a topological map with error‐drift correction based on stereo vision.

, 2011 In this theoretical paper we consider the problem of accurately triangulating a scene plane. Rather than first triangulating a set of points and then fitting a plane to these points, we try to minimize the back-projection errors as functions of the plane parameters directly. As this is both geometrically and statistically meaningful our method performs

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a

On deletion in Delaunay triangulations [PDF]
Proceedings of the fifteenth annual symposium on Computational geometry, 1999 This paper presents how the space of spheres and shelling may be used to delete a point from a d-dimensional triangulation efficiently. In dimension two, if k is the degree of the deleted vertex, the complexity is O(k log k), but we notice that this number only applies to low cost operations, while time consuming computations are only done a linear ...

Advanced Robotics Research, EarlyView.Intelligent Sky Guardians (InSkyGuard) is introduced as a four‐drone swarm that autonomously detects, tracks, and safely captures rogue drones using a coordinated net system. Computer vision and leader–follower control architecture enable synchronized enclosure, while integrated failsafes enhance system reliability. Validated through closed‐environment

El visionado de películas y series subtituladas en el aprendizaje de lengua española en los estudiantes chinos [PDF]
marcoELE. Revista de Didáctica Español Lengua Extranjera, 2022 En esta investigación se propone explorar las relaciones entre el visionado de películas y series subtituladas con el aprendizaje del español dirigido a los estudiantes chinos desde la aproximación a la triangulación investigadora. Para ello, por un lado,
