A self-centering electrostatic microgripper

Journal of Manufacturing Systems, 2008
Abstract Automated microassembly of micro hybrid devices is one fundamental step to reduce their high cost. Often, microassembly deals with fragile and wear-sensitive microparts that must be accurately grasped, positioned, and released or fastened in stable positions.

Self-Centering Frictional Damper (SCFD)

Engineering Structures, 2019
Abstract This paper describes the behavior and design of a new self-centering frictional damper. This device is based on conic friction surfaces that lead to a flag-shaped hysteretic behavior. Its self-centering property and different possible configurations make it a very versatile device to be used in seismic applications of high-rise buildings ...

Initial stiffness of self-centering systems and application to self-centering-beam moment-frames

Engineering Structures, 2020
Abstract There has been considerable development of self-centering seismic force resisting systems in the past few decades, many of which incorporate gap opening mechanisms. Experiments on these self-centering systems often result in an initial stiffness that is less than the predicted theoretical stiffness.

Contradictions of Self-Centered Development

2021
This chapter first presents a model of capitalism that is based on the bargaining power of labor. Capitalism is able to grow because rising real wages create new investment opportunities by capital deepening and market enlargement. However, this process is restricted to a small number of economies in the world, while the Global South remains dominated ...

Self-Centering Buckling-Restrained Braces

Advanced Materials Research, 2013
Buckling-Restrained Brace (BRB) consists of energy dissipative core and a strengthening tube to prevent buckling when subjected to compression. Under cyclic loading, BRB exhibits elastoplastic hysteretic behavior, which leads to certain amount of permanent displacement in the structure after medium to severe earthquake. Residual deformations can result
