01 Aug 2012TL;DR: The principal advantage of the proposed approach is utilization of the trajectory key points from all demonstrations for generation of a generalized trajectory, resulting in a generalization procedure which accounts for the relevance of reproduction of different parts of the trajectories.
Abstract: The main objective of this paper is to develop an efficient method for learning and reproduction of complex trajectories for robot programming by demonstration. Encoding of the demonstrated trajectories is performed with hidden Markov model, and generation of a generalized trajectory is achieved by using the concept of key points. Identification of the key points is based on significant changes in position and velocity in the demonstrated trajectories. The resulting sequences of trajectory key points are temporally aligned using the multidimensional dynamic time warping algorithm, and a generalized trajectory is obtained by smoothing spline interpolation of the clustered key points. The principal advantage of our proposed approach is utilization of the trajectory key points from all demonstrations for generation of a generalized trajectory. In addition, variability of the key points' clusters across the demonstrated set is employed for assigning weighting coefficients, resulting in a generalization procedure which accounts for the relevance of reproduction of different parts of the trajectories. The approach is verified experimentally for trajectories with two different levels of complexity.

TL;DR: In this article, it was shown that uoconvergence is stable under passing to and from regular sublattices, which leads to many applications in functional-analytic aspects of uo-convergence.
Abstract: A net (x
α
) in a vector lattice X is said to uo-converge to x if $$\left| {{x_\alpha } - x} \right| \wedge u\xrightarrow{o}0$$
for every u ≥ 0. In the first part of this paper, we study some functional-analytic aspects of uo-convergence. We prove that uoconvergence is stable under passing to and from regular sublattices. This fact leads to numerous applications presented throughout the paper. In particular, it allows us to improve several results in [27, 26]. In the second part, we use uo-convergence to study convergence of Cesaro means in Banach lattices. In particular, we establish an intrinsic version of Komlos’ Theorem, which extends the main results of [35, 16, 31] in a uniform way. We also develop a new and unified approach to Banach–Saks properties and Banach–Saks operators based on uo-convergence. This approach yields, in particular, short direct proofs of several results in [20, 24, 25].

TL;DR: In this paper, a longitudinal panel examined diffusion of information technology and its spillover from everyday contexts to vacations and found evidence of diffusion with IT advancements through learning, equipment ownership, and improving perceived skills, as well as spillover of IT use and behavior into vacation contexts as a continuation of trip planning and information search beyond home or pre-trip planning.

TL;DR: Voter turnout has consistently declined since the 1980s across a wide range of advanced democracies as discussed by the authors, and much of this decline appears to be the result of young people abstaining.
