Comprehensive introduction to analysis of continuous and discrete-time signals and systems. Linear time-invariant systems, convolution; Fourier series representations of periodic signals; Continuous ...

Physical systems become inherently more complicated and difficult to produce in a lab as the number of dimensions they exist ...

Time crystals break time-translational symmetry rather than spatial symmetry, as ordinary crystals do. Peter Hannaford and Krzysztof Sacha look at how this exotic state could have similar applications ...

Dynamical systems theory continues to offer profound insights into how complex systems evolve over time, with particular focus on the statistical properties that characterise their long‐term behaviour ...

At each sampling time instant, one observes system output and action to form discrete-time rewards. The sampled input-output data are collected along the trajectory of the dynamical system in ...
