Monitoring the Postural Stability of Planar Bipedal Robots using the Moment-Height Stability Measure

Robotics researchers have studied the stability maintenance requirements of bipedal robots since they are inherently unstable. An accurate postural stability measure is required to monitor their dynamic equilibrium conditions. In this article, the novel Moment-Height Stability (MHS) measure, which has previously been developed for monitoring the postural stability of wheeled mobile robots, is developed for that of bipedal robots. The performance of the MHS is evaluated with that of the well

LORRY CONVOY STABILITY TAKING INTO ACCOUNT THE SKEW OF SEMITRAILER AXES

Summary. The mathematical model of a saddle-type lorry convoy is improved taking into account the skew of the axes of a semitrailer. It is shown that the motion of a lorry convoy without the skew of the axes is asymptotically steady. The skew of any axis of a semitrailer results in the worsening of stability of the rectilinear motion conditioned by the oscillations of the towed link.

Discussion on the Factors of Stability for Benchmark Example with a Spherical Failure Surface in Clay

A three-dimensional slope stability problem involving a spherical failure surface in clay is often used in the literature as a benchmark example against which numerical models are validated. In the existing research literature, the analytical expression has been obtained for the factors of safety by assuming plane-strain mechanisms during slope failure. And the hypothesis does not comply with the actual project due to the size effect of slope and surrounding constraints placed on the slope

Effects of postural and cognitive difficulty levels on the standing of healthy young males on an unstable platform

standing, based on motion captured kinematic data, were assessed to analyze the stability of standing. Results showed that vision plays a significant role in maintaining balance in terms of linear metrics. Elimination of visual feedback changed the direction of body sway and increased standing instability. Placement of low stiffness springs led to unstable standing. The cognitive dual task, however, had no effect on the stability metrics and merely could be revealed in the simplest test condition

Results indicate that dynamic preconscious behavior enhances the stability of the system and reduces pedestrian congestion. The passing behavior of the high-speed pedestrian is the main cause for the congestion in the situation of high density. The speed difference will largely influence the anti-congestion ability of the system, so keeping the unity of the speed and group order would maintain the stability

kinds, and train the corresponding BP networks with the two kinds of data. Before using SVM to classify the input data, PCA (principle component analysis) is used to analyze the correlation between sewage quality parameters. Then we predict the value of sewage quality parameters with the fusion results of the two BP networks. Test results of the case study show that fusion of BP networks not only can improve the stability of BP networks but also can improve the prediction accuracy.

THE BENDING MODE CONTROL METHOD OF AFS SYSTEM BASED ON PREVIEW CONTROL

Due to the time-lag of both the mechanical transmission and controller area network (CAN) bus transmission of the Adaptive Front Lighting System (AFS), the actual bending angle of AFS invariably lags behind the steering-wheel angle,which not only makes the real-time response speed of the AFS system slow, but also makes the system stability and the active safety of the vehicle poor. To solve the problem, firstly, the geometrical relations among safety braking distance and the rate of steering

The data provided by these measurements could give useful information to correlate the wear of the track with the frequency of applied loads, helping in the development of a better maintenance strategy of railway networks [2]. In this paper, the monitoring of vertical forces is based on the SMCV (Vertical Loads Monitoring System) method, where shear strains of the rail web are measured with a simple combination of four electrical strain gauges, placed on both sides of the rail web along each

In studies of clinical samples of adults with BPD, structural imaging studies revealed abnormalities predominantly in the frontolimbic areas. Disturbances in emotional information processing—particularly involving negative stimuli—may mediate affective dysregulation as a core feature of BPD. Genetic studies could reveal that the stability of BPD traits in

Growth inhibition was observed only in the case of 13 (including nine S. aureus, three S. xylosus and one S. epidermidis strains) out of 206 strains tested. Important advantage of the produced agent was its high thermal stability. Fifteen minutes of incubation at 90°C did not affect its antimicrobial potential. The highest efficiency of production of the agent was demonstrated in TSB medium after 24 hours at 37°C. The researches revealed
