the main cause of structural damage in buildings subjected to seismic actions is lateral drift. in almost all reinforced concrete (rc) structures, whether designed with walls or frames, it is likely to be the code drift limits that control the design drift. the design drift limits and their contribution to damage may be represented indirectly through the material strain limits. the aim of this ...

Why can we balance a yardstick but not a pencil on the tip of our finger? As with other physical systems, human motor control has constraints, referred to as bandwidth, which restricts the range of frequency over which the system can operate within some tolerated level of error. To investigate control bandwidth, the natural frequency of a stick used during a stick-balancing task was modified by...

Abstract Technical noise present in laser systems can limit their ability to perform high fidelity quantum control of atomic qubits. The ultimate floor for qubits driven with radiation is due spontaneous emission from excited energy levels. goal suppress the technical source below such that it no longer a limiting factor. It has been shown spectral structure have large influence on achievable f...
