Dynamic computational geometry

24th Annual Symposium on Foundations of Computer Science (sfcs 1983), 1983
We consider problems in computational geometry when every one of the input points is moving in a prescribed manner. We present and analyze efficient algorithms for a number of problems and prove lower bounds for some of them.

Computational geometry and discrete computations [PDF]

, 1996
In this paper we describe some problems arising in practical implementation of algorithms from computational geometry. Going to robust algorithms needs to solve issues such as rounding errors and degeneracies. Most of the problems are closely related to the incompatibility between on one side algorithms designed for continuous data and on the other ...

The Price of Upwardness [PDF]

Discrete Mathematics & Theoretical Computer Science
Not every directed acyclic graph (DAG) whose underlying undirected graph is planar admits an upward planar drawing. We are interested in pushing the notion of upward drawings beyond planarity by considering upward $k$-planar drawings of DAGs in which the

An Automatic Process for the Application of Building Permits

Buildings, 2022
Building Information Modeling is an essential element for the digitization of the construction industry and forms the basis for the exchange of model-based data. In order to exploit the full potential of digitization, it is necessary for all stakeholders

Optimal Control of a Rigid Body using Geometrically Exact Computations on SE(3) [PDF]

, 2006
Optimal control problems are formulated and efficient computational procedures are proposed for combined orbital and rotational maneuvers of a rigid body in three dimensions. The rigid body is assumed to act under the influence of forces and moments that

On the Intersection of Computational Geometry Algorithms with Mobile Robot Path Planning

Algorithms, 2023
In the mathematical discipline of computational geometry (CG), practical algorithms for resolving geometric input and output issues are designed, analyzed, and put into practice.

Cell wall target fragment discovery using a low‐cost, minimal fragment library

FEBS Letters, EarlyView.
LoCoFrag100 is a fragment library made up of 100 different compounds. Similarity between the fragments is minimized and 10 different fragments are mixed into a single cocktail, which is soaked to protein crystals. These crystals are analysed by X‐ray crystallography, revealing the binding modes of the bound fragment ligands.

Implicit coupled Hilfer–Hadamard fractional differential systems under weak topologies

Advances in Difference Equations, 2018
In this article, we present some existence of weak solutions for a coupled system of implicit fractional differential equations of Hilfer–Hadamard type. Our approach is based on Mönch’s fixed point theorem associated with the technique of measure of weak

Dual targeting of RET and SRC synergizes in RET fusion‐positive cancer cells

Molecular Oncology, EarlyView.
Despite the strong activity of selective RET tyrosine kinase inhibitors (TKIs), resistance of RET fusion‐positive (RET+) lung cancer and thyroid cancer frequently occurs and is mainly driven by RET‐independent bypass mechanisms. Son et al. show that SRC TKIs significantly inhibit PAK and AKT survival signaling and enhance the efficacy of RET TKIs in ...

Leveraging the mathematics of shape for solar magnetic eruption prediction

Journal of Space Weather and Space Climate, 2020
Current operational forecasts of solar eruptions are made by human experts using a combination of qualitative shape-based classification systems and historical data about flaring frequencies. In the past decade, there has been a great deal of interest in
