Abstract A review presents the state-of-the-art path-following control systems for maritime autonomous surface ships, where special focus is placed on guidance subsystem and subsystem. The path following system one of basic requirements ships since it guarantees that ship can track predefined with small cross-track errors. problem firstly defined, error dynamics are derived from kinematic equat...

A lubricant transfer process that enhanced the wear life of a MoS2 coating has been identified and quantified. A steel ball sliding against a coated steel flat in reciprocating motion produced reservoirs at the turnaround part of the track ends, then emptied them, to provide replenishment similar to what is expected of liquid lubricants. The dynamics of the process were inferred from measuremen...

Solid-state Auger-electron angular distributions are known to be largely independent of the type of excitation, following roughly a cosine law for low ejection energies. In this Letter it is shown that the ion-track dynamics and the corresponding high electron temperatures lead to significant variations of these Auger distributions. Ratios for different degrees of inner-shell ionization versus ...

Robust tracking of vehicles under uncertain, noisy, and discontinuous positioning is a significant part of autonomous navigation in unknown environments. This article suggests two methods for track control, where the initial parameters of the on-line control are physically explainable, the resulting track as well as the control parameters are asymptotically converging and glitches in the locali...

This paper solves the problem of regulating the output of the Arneodo chaotic system (1981), which is one of the paradigms of chaotic dynamical systems. Explicitly, using the state feedback control laws, the output of the Arneodo chaotic system is regulated so as to track constant reference signals as well as to track periodic reference signals. The control laws are derived using the regulator ...

Ichnology deals with the traces of prehistoric organisms and thus with the study of dinosaur footprints and tracks. This paper reports on a reliable and precise methodology developed to integrate high-resolution close range photogrammetry and range sensors for 3D surveys of dinosaur footprints. The 3D footprint and track models recovered here yield a great deal of accurate morphological and mor...

In this paper, we develop a variational method to track and make predictions about a real-world system from continuous imperfect observations about this system, using an agent-based model that describes the system dynamics. By combining the power of big data with the power of modelthinking in the stochastic process framework, we can make many valuable predictions. We show how to track the sprea...
