Positively Charged Polymer‐Brush MOFs for Large‐Area, Pressure‐Resistant Gas Separation Membranes

Advanced Materials, EarlyView.
A universal POPA strategy enables positively charged polymer‐brush MOFs with self‐adaptive interfacial interlocking to resist aggregation under fast processing. This design ensures seamless dispersion within large‐area selective layers, achieving 1 m‐wide roll‐to‐roll fabrication of pressure‐resistant MMCMs with tunable CO2 separation performance ...

Subjective Validity of Figures of Merit for Room Aspect Ratio Design

, 2009
Attempts have long been made to classify a room's low frequency audio reproduction capability with regards to its aspect ratio. Common metrics used have relied on the homogeneous distribution of modal frequencies and from these a number of 'optimal ...

Damping identification in multi-degree-of-freedom systems using the continuous wavelet transform

Vietnam Journal of Mechanics, 2005
The identification of damping in multi-degree-of-freedom vibration systems is a well-known problem and appears to be of crucial interest. Compared to an estimation of the stiffness and mass, the damping coefficient or, alternatively, damping ratio is ...

LSTM‐Based Approach for Stable Identification of Modal Damping Ratio in Building Structures

Structural Control and Health Monitoring
Modal parameters are used as safety assessment indicators for evaluating the structural integrity of buildings in various ways. In particular, the modal damping ratio plays a crucial role in accurately predicting the serviceability and safety of buildings, starting from the initial design stage.
