Control of designed target seeker, used in self-guided anti-aircraft missiles, by employing motors with a constant torque

Aviation, 2014
This paper presents the results of research on control of a designed target seeker (Gapiński, D. 2008), which was carried out using of the so-called “signum” function. The technical feasibility of controlling the seeker axis in the phase of searching the

Quantifying measurement-induced quantum-to-classical crossover using an open-system entanglement measure

Physical Review Research, 2023
The evolution of a quantum system subject to measurements can be described by stochastic quantum trajectories of pure states. Instead, the ensemble average over trajectories is a mixed state evolving via a master equation.

Controlling multiple returnings in non-sequential double ionization with orthogonal two-color laser pulses

Frontiers in Physics, 2023
With the three-dimensional semi-classical ensemble model, we studied the non-sequential double ionization by orthogonal two-color laser pulses. Our calculations show that the proportion of events experiencing multiple returnings, the sum of the final ...

Wigner Trajectory Characteristics in Phase Space and Field Theory [PDF]

, 1998
Exact characteristic trajectories are specified for the time-propagating Wigner phase-space distribution function. They are especially simple---indeed, classical---for the quantized simple harmonic oscillator, which serves as the underpinning of the ...

Exploring the behavior feature of complex trajectories of ships with Fourier transform processing: a case from fishing vessels

Frontiers in Marine Science, 2023
The significant uncertainty and complexity of vessels at sea poses challenges for regulatory bodies in the fishing industry. This paper presents a method for identifying fishing vessel trajectory characteristics involving the Fourier series transform ...

Dynamical phase trajectories for relativistic nuclear collisions [PDF]

, 2006
Central collisions of gold nuclei are simulated by several existing models and the central net baryon density {rho} and the energy density {epsilon} are extracted at successive times for beam kinetic energies of 5-40 GeV/nucleon.

Learning Poisson Systems and Trajectories of Autonomous Systems via Poisson Neural Networks [PDF]

IEEE Transactions on Neural Networks and Learning Systems, 2020
We propose the Poisson neural networks (PNNs) to learn Poisson systems and trajectories of autonomous systems from data. Based on the Darboux–Lie theorem, the phase flow of a Poisson system can be written as the composition of: 1) a coordinate ...
