Merging polygons on two-layer printed circuit board [PDF]
Tekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2011 A method is proposed for solving the problem of connection of maximum number of isolated islands of metallized areas of the same chain, located on different layers of the printed circuit board.

Pallas, 2019 The thematic of the protohistoric wooden architecture in temperate Europe has undergone a significant progress since the second half of the 20th century. Nevertheless, the question of diagonal braces is often avoided for this period and the hypothesis of

, 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

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.

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 ...

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

Grip and Grasp: Lizard Claw Inspired Robotic Manipulators
Advanced Robotics Research, EarlyView.Our study identifies the most effective lizard claw shape for use as an end effector in a bioinspired robotic manipulator. By examining key geometric features and combining them into comparative indices, the Crotaphytus collaris claw is found to be the best fit.

Fast Greedy Triangulation Algorithms [PDF]
, 1994 The greedy triangulation of a set of n points in the plane is the triangulation obtained by starting with the empty set and repeatedly adding the shortest compatible edge where a compatible edge is dened to be an edge that does not intersect any ...
