We consider the problem of state and parameter reconstruction for uncertain dynamical systems that cannot be transformed into the canonical adaptive observer form. The uncertainties are allowed to be both linearly and nonlinearly parameterized functions of state and time. We provide a technique that allows successful reconstruction of uncertain state and parameters for a broad range of dynamical systems that belong to this class. In contrast to conventional approaches our technique is based on the concepts of weakly attracting sets, and non-uniform convergence and Poisson stability rather than the notion of Lyapunov stability. Relevance of the proposed approach to the domains of control and system identification is illustrated with examples.

Some analytical models were applied to describe the front separation flows formation. To realize the steady flows with isobaric front separation regions in numerical experiments the method of transformation of the energy deposition region geometry was developed. The method was applied for blunt and sharpen "thermal spiked" bodies. "Shock-free" separation flows initiated by subsonic temperature wakes were examined.

This paper presents new results in the research and development of recently proposed design of the offshore wind power plant with large-scale floating turbine (WEMU design).The main objective of this study is to investigate the vertical vortex inside the turbine,flow interaction with the turbine due to the pitch caused by waves,and to estimate the additional pitching moment. Numerical experiments for new geometrical model design of rotor are carried out using simulation tools based on a finite volume *** stable vortexes are found between the upper and low rings,which connect the blades along vertical ***, nonlinear equations for the floating rotor equilibrium are solved by an iterative Newton *** floating rotor is proved to have sufficient stability.

New theoretical results for the conception of a flow-over-body control by an artificial formation of front separation regions, initiated by a localized energy deposition in the upstream flow, are presented. Euler equations and mathematical abstraction of the "energy source" where use for numerical investigations. The hysteresis effect for small energy sources was found: depending of the process history, for the same conditions, two different solutions for the flow-over-body problem can be obtained. The first solution is the regime with a steady front separation region, and the second one is the regime with a pulsing separation region and a complicated shock wave structure. Also, some conclusions concerning the influence of the energy source parameters on a separation region formation are drowned, and the mechanism of pulsing regimes formation is explained. It is underlined, that the instability of front separation regions for very small energy sources, that becomes apparent as generation of large-scale vortex structures, is one of the possible principal problem for the new conception realization.

A (2×2) structure formed by thallium (Tl) atoms on the Si(001) surface at 0.5 monolayer coverage at room temperature has been studied by a tensor low-energy electron-diffraction (LEED) analysis. Twenty-four structural models were tested. The valley-bridge para dimer model, being produced also by other trivalent metals, was found to be the most optimal. It is concluded, therefore, that the so-called “inert pair effect” of Tl atoms does not play a significant role in the case of this (2×2) structure. The structural parameters obtained by first-principles total-energy calculations are in good agreement with those obtained by the LEED analysis.
