The dynamic performance of structures under traveling loads should be exactly analyzed to have a safe and reasonable structural design. Different higher-order shear deformation theories are proposed in this paper to analyze the dynamic stability of thick elastic plates carrying a moving mass. The displacement fields of different theories are chosen based upon variations along the thickness as c...

The simple harmonic vibration, damping vibration and forced vibration of an oscillator attached to the massless spring are always discussed in general mechanics courses. In this article, we focus on the heavy-spring conditions. We first investigate the general situation where both viscous resistance and applied force are considered under the perspective of the renormalization group theory. Then...

During goal-directed tasks, such as lifting low-lying objects, the human motor system regulates the body’s centre of mass (CoM) position to maintain equilibrium and prevent falling [1]. During lifting, any voluntary trunk movement will perturb that equilibrium, which will elicit an automatic postural response requiring the coordinated control of several joints [2]. To actively counter perturbat...

In this paper, based on maximizing the outrigger-belt truss system’s strain energy, a methodology for determining the optimum location of an outrigger-belt truss system is presented. Tall building structures with combined systems of framed tube, shear core and outrigger-belt truss system’s are modeled using continuum approach. In this approach, the framed tube system is modeled as a cantilevere...

In this paper, we propose a region-based blend shape approach to facial expression cloning that automatically extracts a set of coherently-moving regions of the source face model and their counterparts in the target face model without any extra input data except the source and target key face models and their correspondence. We represent a face mesh as a mass-spring network to define two measur...

a project was established to develop a procedure for the selection, design, installation, test and evaluation of mass-flow rate measurement systems for root crop harvesting and to assess the consistency and precision of the weighing systems incorporated into crop feed arrangements in both laboratory and field studies. studies were conducted to evaluate conveyor belt weighing systems using an ex...
