Distribution of lateral active earth pressure on a rigid retaining wall under various motion modes
The design of retaining walls depends on the magnitude of active pressure exerted from the backfill. Therefore, estimating the scale of this pressure is a fundamental factor in the design. In this study, to assess the active earth pressure, a rigid retaining wall was built capable of translating and/or rotating with adjustable speed. Further, several physical tests were conducte...
متن کاملMotion of Particles under Pseudo-Deformation
In this short article, we observe that the path of particle of mass $m$ moving along $mathbf{r}= mathbf{r}(t)$ under pseudo-force $mathbf{A}(t)$, $t$ denotes the time, is given by $mathbf{r}_d= int(frac{dmathbf{r}}{dt} mathbf{A}(t)) dt +mathbf{c}$. We also observe that the effective force $mathbf{F}_e$ on that particle due to pseudo-force $mathbf{A}(t)$, is given by $ mathbf{F}_e= mathbf{F} mat...
متن کاملEvaluation of Early Active Controlled Motion in Flexor Tendon Repair
Objectives: The objective was to determine the results of early active controlled motion in the patients rehabilitated by our new protocol. Methods: 91 fingers in 64 patients with flexor tendon repair in all zones were enrolled in a single group (quasi-experimental) clinical trial. 58 fingers in 43 patients were assessed at least three months postoperatively. Outcomes were defined using the ...
متن کاملOn the Observability of Robot Motion Under Active Camera Control
We de$ne a measure of “observability” of robot motion that can be used in evaluating a hand/eye set-up with respect to the ease of achieving vision-based control. This eztends the analysis of “manipulability” of a robotic mechanism in [9] to incorporate the effect of visual features. We discuss how the observability measure can be applied for active camera placement and for robot tmjectory plan...
متن کاملAutomatic Real-Time Localization of Frowning and Smiling Faces under Head Rotation Variations
A new method for real-time face localization from a streaming color video was developed. The method consisted of three stages. First, the face-like skin-colored image region was segmented from the background and transformed into the grey scale representation. Second, the cropped image was convolved with Sobel operator in order to extract local oriented edges at 16 orientations. The extracted lo...
