This paper introduces a real-time tracking system of human arm motion, specifically intent to be used for homebased rehabilitation. Both vision and inertial sensors are employed in this system to track the arm movement in 3D and in real time. Different data modalities from two sensors are fused by using arm structure relationship and geometry information. The occlusion problem, which is one of ...

The results presented in this paper apply to a generic vehicle that makes use of geometry changes to modulate the heat, drag, and acceleration loads while entering a planetary atmosphere. Two structural concepts for implementing the cone angle variation, namely a segmented shell and a corrugated shell, are presented. A structural analysis of the corrugated shell configuration shows that the str...

The effect of track geometry on vehicle vibration is a major concern in high-speed rail (HSR) operation from the perspectives ride comfort and safety. However, how to quantitatively characterize relation between them remains problem be solved quality assessment. By using fractal analysis, this paper studies detailed correlation surface alignment irregularities car body vertical lateral accelera...

The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

There are some known properties on curves of constant width and Zindler their relationship with offsets front tire-track in convex geometry. In this work, a generalization all these concepts results to hedgehogs is presented. Discontinuity issues coming from the common parametric definition track solved parameterizations by support function. Finally, it seen that there one-to-one correspondence...

We present the design and performance analysis of a new integrated track reconstruction code developed for the STAR experiment at RHIC. The code is meant to replace multiple previous tracker codes written in FORTRAN many years ago, and to readily enable integration of new and varied detector components. The new tracker is written from the ground up in C++ using a strong object -oriented model. ...

Track Geometry parameters from rail track inspection are regulated within unique safety limits for different classes. This paper focuses on developing an index that combines and quality because of the inefficiency having corrective maintenance activities between routine cycles when federal geometry violated. combination is achievable by summarizing multivariate parameters, as improvement to pre...
