In this paper, we study the output feedback stabilization for a scalar conservation law with nonlocal velocity that models highly re-entrant manufacturing system as encountered in semiconductor production. By spectral analysis, obtain complete result on exponential linearized control system. Moreover, by using Lyapunov function approach, also prove results nonlinear certain cases.
The general theory on exact boundary controllability for first order quasilinear hyperbolic systems requires that the characteristic speeds of system do not vanish. This paper deals with controllability, when this is case. Some important models are also shown as applications main result. strategy uses return method, which allows one in certain situations to recover nonzero speeds.
This paper is devoted to discuss the stabilizability of a class 2 × non-homogeneous hyperbolic systems. Motivated by example in Section 5.6 Bastin and Coron’s book 2016, we analyze influence interval length L on system. By spectral analysis, prove that either system stabilizable for all > 0 or it possesses dichotomy property: there exists critical c such ∈ (0, ) but unstabilizable [ ,+∞). In addition, , +∞), obtain can reach equilibrium state finite time backstepping control combined with...
The effect of lanthanum addition on the formation behaviors inclusions in Q355B weathering steel was investigated by laboratory experiments and thermodynamic calculations. results demonstrate that main without La are large-sized irregular Al2O3 MnS, with an average size about 5.35 μm. As content increases from 0.0075 to 0.0184 wt.%, dominant transform LaAlO3, Al2O3-LaAlO3 into La2O3, LaAlO3-La2O3. Meanwhile, significantly decreases 3.4 2.48 μm distribution is more dispersive. When 0.0425...

This study systematically investigates the mechanism of NOx emissions during sintering process, with a focus on utilization biochar as an auxiliary fuel to replace portion coke traditionally used in iron ore sintering. The research involved simulation raw material ratios using ore, biochar, and powder. Substitution levels for were set at 0%, 20%, 40%, 50%, 60%, 80%, 100%. process monitored flue gas detection system. Simultaneously, comprehensive analysis sintered was conducted aim producing...
Phase change materials (PCM) have been widely used in Thermal Energy Storage (TES) Systems. Considering the energy efficiency and use of domestic hot water, melting temperature range phase is considered to be optimal 50–60 °C. The most commonly sodium acetate trihydrate-based material, which has advantages high latent heat low price, but its supercooling, thermal conductivity, separation affect application. Therefore, this paper trihydrate, disodium hydrogen phosphate dodecahydrate (DSP),...
