Proposition : If we apply one of the three equation operations to a system of linear equations, then the original system and the transformed one are equivalent. Matrices Def: A matrix is a rectangular array of numbers. For an system of linear equations, the matrix [a11a12⋯a1na21a22⋯a...
This study investigates the application of different ultrasonic Non-Destructive tests to assess Delayed Ettringite Formation, in concrete samples exhibiting low kinetic expansions (and up to 0.21%). Linear and nonlinear Resonant Ultrasonic Spectroscopy and Acoustic Emission tests were used. Scanning Electron...
By knowing this trend and measuring the proposed indices, it would be possible to know the torque applied on the bolt and therefore assess the health state of a bolted structure. 展开 关键词: acoustic moment harmonic generation bolt loosening/tightening sidebands nonlinear acoustics ...
jax-sysid is a Python package based on JAX for linear and nonlinear system identification of state-space models, recurrent neural network (RNN) training, and nonlinear regression/classification. The algorithm can handle L1-regularization and group-Lasso regularization and relies on L-BFGS optimization...
Conclusion: Nonlinear control of heart rate was affected immediately after short duration spaceflight, but not to the extent that the astronauts experienced orthostatic intolerance. 展开 关键词: Practical, Experimental/ cardiovascular system electrocardiography haemodynamics zero gravity experiments/ nonlinear ...

without nonlinear mappings gives similar performances. Without using kernels, one can efficiently train a much larger set via linear classification/regression. These data usually have a large number of features. Document classification is an example. Warning: While generally liblinear is very fast, ...
