This paper presents a camera tracking system for the spatial stabilization of Augmented Reality (AR) media. Our approach integrates both artificial landmarks (fiducials) and natural features for camera tracking. Artificial landmarks are used for system initialization and computation of initial camera pose. Robust and extendible tracking is achieved by dynamically calibrating the 3D positions of...

This paper studies the problem of decentralized measurement feedback stabilization of nonlinear interconnected systems. As a natural extension of the recent development on control vector Lyapunov functions, the notion of output control vector Lyapunov function (OCVLF) is introduced for investigating decentralized measurement feedback stabilization problems. Sufficient conditions on (local) stab...

This study explored the feasibility of lignin based biofuel co-product (BCP) for subgrade soil stabilization, and more specifically, its impact on Hot-Mix Asphalt (HMA) pavement performance using the Mechanistic-Empirical Pavement Design Guide (MEPDG). The HMA pavement systems with BCP stabilized subgrade under different traffic and climate conditions were modeled using mechanistic based damage...

We describe the design, construction, and characterization of a medium-finesse Fabry-Perot cavity for simultaneous frequency stabilization of two lasers operating at 960 and 780 nm wavelengths, respectively. The lasers are applied in experiments with ultracold rubidium Rydberg atoms, for which a combined laser linewidth similar to the natural Rydberg linewidth (≈10  kHz) is desired. The cavity,...

The phase synchronization problem requires each node to infinitely transfer from one phase to the next one under the restriction that at most two consecutive phases can appear among all nodes. In this paper, we propose a self-stabilizing algorithm under the parallel execution model to solve this problem for semi-uniform systems of general graph topologies. The proposed algorithm is memory-effic...

This paper describes a self-stabilizing version of an algorithm presented by A. Mazurkiewicz [Inform. Process. Lett. 61 (1997) 233–239] for enumerating nodes by local rules on an anonymous network. The result improves the reliability aspects of the original algorithm and underlines the importance of a non-ambiguous topology for a network.  2001 Elsevier Science B.V. All rights reserved.

The exit time and the exit location of a non-markovian diffusion is analyzed. More particularly, we focus on the so-called self-stabilizing process. The question has been studied by Herrmann, Imkeller and Peithmann in [HIP08]. Some results similar to the ones of Freidlin and Wentzell for classical diffusions have been proved. We aim to provide the same results by a method more intuitive. Our ar...

We examine the task of constructing self-stabilizing real-time decision systems, which take their input from an external environment, and present a series of results concerning compilers which force the property of self-stabilization onto such systems. We consider compilers that do and do not preserve termination applied to nite state and innnite state programs.

Dynamics in a distributed system are self-stabilizing if they are guaranteed to reach a stable state regardless of how the system is initialized. Game dynamics are uncoupled if each player’s behavior is independent of the other players’ preferences. For uncoupled players, recognizing an equilibrium is a distributed computational task. Self-stabilizing uncoupled dynamics, then, capture both resi...
