In the beginning, Eiichi was the latest in a striking line of ingenious Japanese organic chemists. In their hands, meticulous attention to detail in the tuning of reagents and conditions has given the community a cornucopia of reliable synthetic procedures of great utility. A substantial segment of the name reactions of the second half of the 20th century are Japanese; the 2010 Nobel Prize in C...

We present a novel trajectory computation algorithm to smooth jerky collision-free paths computed by samplebased motion planners. Our approach uses cubic B-splines to generate G or curvature continuous trajectories. The algorithm performs local spline refinement to compute smooth, collision-free paths in narrow passages and satisfy velocity and acceleration constraints. We also present a fast a...

To function in the real world, a robot must be able to understand human intentions. This capability depends on accurate and reliable detection and tracking of trajectories of agents in the scene. We propose a visual tracking framework to generate and maintain trajectory information for all agents of interest in a complex scene. We employ this framework in an intent recognition system that uses ...

this paper deals with a globally convergent adaptive and sliding mode control of a cart-pole inverted pendulum for trajectory tracking in the presence of a bounded measurement noise and parameter uncertainty. two kinds of controllers have been used for evaluation of tracking error in presence of a bounded noise; as a result, we want to compare that at what time we can see the convergence of tra...

This paper proposes a reliable method for tracking the trajectory of video objects using the vector Kalman predictor. Video objects, within the scope of this paper, are defined as groups of image pixels coherent spatially as well as in their values of luminance. The extent to which the quality of the unsupervised region split and merge segmentation affects the accuracy of the tracker is discuss...

The question of how to validate and interpret correctly the waiting time probability density functions (WT-PDFs) from single molecule data is addressed. It is shown by simulation that when a stretched exponential WT-PDF, , generates the off periods of a two-state trajectory, a reliable recovery of the input α τ φ φ ) / ( 0 ) ( t off e t − = ) (t off φ from the trajectory is obtained even when t...

in this study, the problem of determining an optimal trajectory of a nonlinear injection into orbit problem with minimum time was investigated. the method was based on orthogonal polynomial approximation. this method consists of reducing the optimal control problem to a system of algebraic equations by expanding the state and control vector as chebyshev or legendre polynomials with undetermined...
