Machines, 2023 In this article, a mathematical model has been developed for calculating the energy-power parameters of the drawing process in monolithic dies on straight-line drawing machines, and its adequacy has been validated in experimental wire drawing on a ...

On-line segmentation of freehand sketches by knowledge-based nonlinear thresholding operations [PDF]
, 2001 This paper describes an on-line procedure for segmenting freehand sketches into 2D primitives and smooth curves by knowledge-based nonlinear thresholding operations. Drawing position, direction, speed and acceleration information is used for establishing

Kinematic characteristics in patients with subcortical vascular cognitive impairment: a quantitative analysis of digitized spiral drawing metrics [PDF]
Scientific ReportsSubcortical vascular cognitive impairment (SVCI) is caused by white matter degeneration. Multiple lacunar infarction due to deep small vascular disease around the subcortical structure and incomplete infarction of white matter owing to decreased ...

A conceptual design tool: Sketch and fuzzy logic based system [PDF]
, 2001 A real time sketch and fuzzy logic based prototype system for conceptual design has been developed. This system comprises four phases. In the first one, the system accepts the input of on-line free-hand sketches, and segments them into meaningful parts ...

Drawing Halin-graphs with small height
Journal of Graph Algorithms and Applications, 2022 In this paper, we study how to draw Halin-graphs, i.e., planar graphs that consist of a tree $T$ and a cycle among the leaves of that tree. Based on tree-drawing algorithms and the pathwidth $pw(T) $, a well-known graph parameter, we find poly-line ...

Equilateral Spherical Drawings of Planar Cayley Graphs
Journal of Graph Algorithms and Applications, 2021 In this paper, we study equilateral spherical drawings of planar Cayley graphs. We focus on the case when the underlying group is generated by two rotations.

Journal of Graph Algorithms and Applications, 2017 We introduce a new type of graph drawing called "rook-drawing". A rook-drawing of a graph $G$ is obtained by placing the $n$ nodes of $G$ on the intersections of a regular grid, such that each row and column of the grid supports exactly one node.

From on-line sketching to 2D and 3D geometry: A fuzzy knowledge based system [PDF]
, 2000 The paper describes the development of a fuzzy knowledge based prototype system for conceptual design. This real time system is designed to infer user’s sketching intentions, to segment sketched input and generate corresponding geometric primitives ...

Non-aligned Drawings of Planar Graphs
Journal of Graph Algorithms and Applications, 2017 A non-aligned drawing of a graph is a drawing where no two vertices are in the same row or column. Auber et al. showed that not all planar graphs have a non-aligned planar straight-line drawing in the $n\times n$-grid.

On Extending a Partial Straight-Line Drawing [PDF]
, 2005 We investigate the computational complexity of the following problem. Given a planar graph in which some vertices have already been placed in the plane, place the remaining vertices to form a planar straight-line drawing of the whole graph.
