Steering Mirror System with Closed-Loop Feedback for Free-Space Optical Communication Terminals [PDF]
AerospacePrecision beam pointing plays a critical role in free-space optical communications terminals in uplink, downlink and inter-satellite link scenarios. Among the various methods of beam steering, the use of fast steering mirrors (FSM) is widely adopted ...

Decomposable Free Loop Spaces [PDF]
Canadian Journal of Mathematics, 1987 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.

Virtual Dual-Loop Feedback Control with Model-Construction Linear Extended State Observer for Free Space Optical Communication [PDF]
Sensors, 2019 The stable alignment and transmission of free space optical communication (FSO) is susceptible to internal dynamics and external disturbances. In this paper, a virtual dual-loop feedback control (VDFC) with model-construction linear extended state ...

Application of Cad-Cam for Fabrication of Metal-Free Band and Loop Space Maintainer [PDF]
Journal of Clinical and Diagnostic Research, 2017 An ideal occlusion with proper tooth alignment and fully functional teeth is the ultimate goal of all dental treatments. Premature extraction of deciduous teeth is a common sequeale of untreated dental caries in teeth in which the damage is far beyond ...

Cartan calculi on the free loop spaces [PDF]
Journal of Pure and Applied Algebra, 2022 A typical example of a Cartan calculus consists of the Lie derivative and the contraction with vector fields of a manifold on the derivation ring of the de Rham complex. In this manuscript, a second stage of the Cartan calculus is investigated. In a general setting, the stage is formulated with operators obtained by the André-Quillen cohomology of a ...

On the cohomology algebra of free loop spaces [PDF]
Topology, 2001 Let $X$ be a simply connected space and $\Bbb K$ be any field. The normalized singular cochains $N^*(X; {\Bbb K})$ admit a natural strongly homotopy commutative algebra structure, which induces a natural product on the Hochschild homology $HH_* N^*X$ of the space $X$.

The cyclic groups and the free loop space
Commentarii Mathematici Helvetici, 1987 The authors study \(\tilde T(Y)=T(Y)/T(point)\), where \(T(Y)=ES^ 1\times_{S^ 1}F(Y)\) \((F(Y)=space\) of free loops on Y, with the natural \(S^ 1\)-action). The main result establishes a homology isomorphism \(Z(X)\to \tilde T(\Sigma X)\), for a connected complex X, where \(Z(X)\) is a combinatorial functor of X, obtained from the Dyer- Lashof ...
