One of the key challenges in robotic bipedal locomotion is finding gait parameters that optimize a desired performance metric, such as robustness or energy efficiency. Typically, gait optimization requires extensive robot experiments and specific expert knowledge. Instead, we propose to apply data-driven machine learning to automate and speed up the process of gait optimization. In particular, ...

© Appl. Rheol. 20 (2010) 63293 DOI: 10.3933/ApplRheol-20-63293 Abstract: Bitumen is undoubtedly the most important material in the construction and rehabilitation of flexible road pavements. By increasing the temperature, bitumen changes from brittle solid, to viscoelastic solid and finally to Newtonian fluid. The rheological characteristics of bitumen also vary greatly due to aging, which is a...

Characteristic polarization state theory is restudied for the symmetric coherent Sinclair scattering matrix case. First, the geometric relations of the characteristic polarization states on the Poincaré sphere are derived. Based on these relations, simple formulas are given for all of the characteristic polarization states of this Sinclair matrix in Stokes vector form. From the formulation, it ...

We estimate the internal and external parameters of the camera, and simultaneously the distortion S parameters. Our aim is the selection of the best distortion model, using stiatistical test for the importance of distortion parameters. Also we examine the accuracy in camera parameter estimation and 30 reconstruction, in relation with the noise in the image. We answer the question “until which l...

A geometrical argument is outlined to show the (already known) instability of an inflected liquid bridge between parallel planes in the case of equal contact angles. In contrast to the behavior of liquid bridges between parallel planes, it is shown that a liquid bridge between spheres exists which is stable and has two inflections. Along the way, a result relating stability and dH/dV for a fami...

This paper is to review important device parameters as the figures of merit (FOM) to understand the device characteristics for analog/RF applications. These FOM should be characterized and evaluated in technology development and model generation for analog/RF technologies. This paper has tried to show these FOM with both measured data and model simulation to help both technology developers and ...

We present a parametric method to automatically identify people in monocular low-resolution video by estimating the height and stride parameters of their gait. Stride parameters (stride length and cadence) are functions of body height, weight, and gender. Previous work has demonstrated effective use of these biometrics for identification and verification of people. In this paper, we show that p...
