Hypo-paradoxical Linkages: Linkages That Should Move-But Don't
Nir Shvalb, Oded Medina
While paradoxical linkages famously violate the Chebyshev-Grubler-Kutzbach criterion by exhibiting unexpected mobility, we identify an opposing phenomenon: a class of linkages that…
Ramsey Approach to Quantum Mechanics
Edward Bormashenko, Nir Shvalb
Ramsey theory enables re-shaping of the basic ideas of quantum mechanics. Quantum observables represented by linear Hermitian operators are seen as the vertices of a graph. Relatio…
Navigation Through Endoluminal Channels Using Q-Learning
Oded Medina, Liora Kleinburd, Nir Shvalb
In this paper, we present a novel approach to navigating endoluminal channels, specifically within the bronchial tubes, using Q-learning, a reinforcement learning algorithm. The pr…
Ramsey Theory and Geometry of Closed Loops
Nir Shvalb, Mark Frenkel, Shraga Shoval +1
We apply the Ramsey theory to the analysis of geometrical properties of closed contours. Consider a set of six points placed on a closed contour. The straight lines connecting thes…
Symmetric Configuration spaces of linkages
David Blanc, Nir Shvalb
A of a linkage is a possible positioning of in and the collection of all such forms the configuration space of . We here…
Thermophoretic Levitation of Solid Particles at Atmospheric Pressure
Pritam Kumar Roy, Irina Legchenkova, Leonid A. Dombrovsky +7
Separation and transportation of small particles are important processes in various applications such as the food and pharmaceutical industries. Although mechanical, chemical or el…
Configuration spaces of spatial linkages: Taking Collisions Into Account
David Blanc, Nir Shvalb
We construct a completed version C(Gamma) of the configuration space of a linkage Gamma in R^3 which takes into account the ways one link can touch another. We also describe a simp…
A Navigation Function For Uncertain Environment
Shlomi Hacohen, Shraga Shoval, Nir Shvalb
This paper introduces a novel motion planning algorithm for stochastic scenarios. We extend the concept of a navigation function to such scenarios. Our main idea is to consider bot…
Generic singular configurations of linkages
David Blanc, Nir Shvalb
We study the topological and differentiable singularities of the configuration space C(Γ) of a mechanical linkage Γin d-dimensional Euclidean space, defining an inductive sufficien…
