the constitutive relationships of the rubber materials that act as the main spring of a hydraulic engine mount are nonlinear. in addition to material induced nonlinearity, further nonlinearities may be introduced by mount geometry, turbulent fluid behavior, temperature, boundary conditions, decoupler action, and hysteretic behavior. in this research all influence the behavior of the system only...
| An adaptive attitude control law is presented that realizes linear closed-loop dynamics in the attitude error vector. The Modiied Rodrigues Parameters (M-RPs) are used as the kinematic variables since they are non-singular for all possible rotations. The desired linear closed-loop dynamics can be of either PD or PID form. Only a crude estimate of the moment of inertia matrix is assumed to be ...
Many of the current implementations of exoskeletons for the lower extremities are conceived to either augment the user's load-carrying capabilities or reduce muscle activation during walking. Comparatively little research has been conducted on enabling an exoskeleton to increase the agility of lower-limb movements. One obstacle in this regard is the inertia of the exoskeleton's mechanism, which...

current practices in railway track analysis and design are reviewed and discussed in this paper. the mechanical behavior of railway track structure comprising of various components has not been fully understood due to the railway track structural complexity. although there have been some improvements in the accuracy of current track design methods in recent decades, there are still considerable...
Background & Objective: Considering the current unstable environment, organizations are faced with numerous changes and should adapt to various environmental factors. The present study aimed to evaluate the dimensions and components of organizational inertia at Mazandaran University of Medical Sciences (MUMS), Iran. Materials and Methods: This applied study was conducted based on an explorator...
Public transport companies face great expenses. In order to be profitable companies, they need to reduce costs in all aspects. In addition, many countries have increased taxes to force transport companies to reduce their fuel consumption and, thus, greenhouse effect emissions. Efficient driving is the cheapest way to achieve this goal. In this paper, we analyze the economic impact of one of the...
Methods and material Twenty-four participants (mean age 21.8 yrs ± 3.5 yrs, height 1.75 m ± 0.09 m and body mass 71.0 kg ± 10.6 kg) were recruited. A marker set consisting of 20 x 10 mm markers was developed to track in-shoe joint kinematics [1]. Reliability and accuracy estimates of calibration marker placement on the shoe were determined. To track inshoe foot motion, 12 mm diameter holes were...
