This paper presents a new computational procedure for optimization of structures subjected to dynamic loads. The problem is formulated with discrete design variables that represent the members from table commercially available members. Also, requirements in American Institute Steel Construction (AISC) manual are as constraints. results nondifferentiable problem. In procedure, load transformed i...

This paper contains a proposition of new method determining the fatigue life elements subjected to non-stationary loads. The model was based on determination time-variable equivalent weighted amplitude. amplitude is derived continuous basis as arithmetic mean nth root amplitudes that occur up given time. analysis proposed carried out selected literature insights specimens made P91 and P92 steel...

Currently, most rehabilitation/nursing robots attach the human body to end of robot by ‘binding’ solution, which makes operation complicated and greatly limits their applications. Therefore, it is necessary study a universal gripper that can directly grasp limbs as end-effector robot. Inspired hand, this paper proposes bionic under-actuated imitates structure hand. The concept Equivalent Link L...

In this paper, we consider the relationship between supermodularity and risk aversion. We show that supermodularity of the certainty equivalent implies that the certainty equivalent of any random variable is less than its mean. We also derive conditions under which supermodularity of the certainty equivalent is equivalent to aversion to mean-preserving spreads in the sense of Rothschild and Sti...
