On the Free Loop Space of Homogeneous Spaces
American Journal of Mathematics, 1987This paper shows that if M is a compact simply connected homogeneous space which is not diffeomorhic to a symmetric space of rank one, then the Betti numbers with \({\mathbb{Z}}_ 2\)-coefficients of the free loop space of M are unbounded. As a corollary, the authors extend a result of Gromoll-Meyer to show that any Riemannian metric on M has infinitely

Series elasticity for free free-space motion for free
2014 IEEE Haptics Symposium (HAPTICS), 2014Series elastic actuators are used to significant advantage in many robot designs but have not found their way into the design of haptic devices. We use a pneumatic circuit to realize both a flexible power transmission as well as the elastic element in a series elastic actuator.

Enemy-Free Space for Parasitoids
Environmental Entomology, 2014Natural enemies often cause significant levels of mortality for their prey and thus can be important agents of natural selection. It follows, then, that selection should favor traits that enable organisms to escape from their natural enemies into "enemy-free space" (EFS).

112th ACSA Annual Meeting Proceedings, Disruptors on the Edge
This presentation shares the inception of a new student-driven architecture publication, a poster-zine called SPACE FOR FREE. The zine is an outgrowth of a fourth year option studio course, which asks students to use walking and close observation as a main method in order to learn from existing spaces in our city – in this case, Toronto, Canada.

Path Connectivity of the Free Space
IEEE Transactions on Robotics, 2012This paper revisits the notion of free configuration space and reviews some of its path-connectivity-related properties. The literature on motion planning reveals at least three different definitions for the free configuration space of a robot in the presence of obstacles.

Quantum cryptography in free space
Optics Letters, 1996The range of quantum cryptography systems using optical fibers is limited to roughly 30 km because amplifiers cannot be used. A fully operational system for quantum cryptography based on the transmission of single photons in free space under daylight conditions has been demonstrated.

Cognition of free space for planning the shortest path: A framed free space approach
Pattern Recognition Letters, 2001Summary: An algorithm incorporating two novel ideas is proposed to improve the time performance of the quad tree-based method for planning the shortest path from a given source to any given destination. One of the novel ideas is to combine the free quads.

Free-space diffractions are an optical phenomenon where light appears to "bend" around the geometric edges and corners of scene objects. In this paper we present an efficient method to simulate such effects. We derive an edge-based formulation of Fraunhofer diffraction, which is well suited to the common (triangular) geometric meshes used in computer ...

On the free loop spaces of a toric space
Boletín de la Sociedad Matemática Mexicana, 2016A moment-angle complex (a special case of a polyhedral product) is a space parametrized by a simplicial complex and equipped with a torus action. The main example is the moment-angle complex \(Z_K =(D^2, S^1)^K\) [\textit{V. M. Buchstaber} and \textit{T. E. Panov}, Toric topology.

In this paper we study the spaces X having the property that the space of free loops on X is equivalent in some sense to the product of X by the space of based loops on X. We denote by ΛX the space of all continuous maps from S1 to X, with the compact-open topology.
