This technical note is concerned about the finite-time stability and stabilization for Itô stochastic systems with Markovian switching. A mode-dependent parameter approach proposed to give a sufficient condition stability, its superiority common analyzed. Moreover, studied two new conditions existence of state output feedback controllers are presented in terms coupled matrix inequalities. N-mode algorithm given solving obtained inequalities arising from stability(stabilization). Finally, an...
A multi-scale micromechanical model is proposed to predict the damage degree of hybrid fiber-reinforced concrete under or after high temperatures. The thermal degradation generally composed cement paste caused by decomposition and incompatibility, deterioration aggregates fibers, interfacial between matrix. In this model, four levels structures are considered when derived; namely, equivalent calcium silicate hydrate (C–S–H) product level, level. At decompositions C–S–H hydroxide taken into...
Studying the crack propagation of ultrahigh-performance concrete (UHPC) helps us understand its mechanical mechanism and assess structural performance. A novel method for separation characteristic evaluation was developed in this work. The proposed introduces robust principal component analysis (RPCA) to decompose a data matrix from video streams stacked into low-rank sparse matrix, which represents information. Compared with cracks binary image, obtained preserves rich information that can...
The paper focuses on the flow structures and mass rates of thermally driven smoke flows induced by fires in long transportation tunnels under natural ventilation. important influencing factors including heat release rate (HRR), tunnel width height, are taken into consideration. mechanism movement is explored. results show that for a fire naturally ventilated tunnel, there exists critical point which dependent HRR geometry. This defined as location where layer thickness outgoing increase...
Abstract In this paper, finite‐time stability and stabilization problems for a class of linear stochastic systems are studied. First, new concept is defined systems. Then, based on matrix inequalities, some sufficient conditions under which the stochastically stable given. Subsequently, studied existence state feedback controller dynamic output presented by using inequality approach. An algorithm given solving inequalities arising from (stabilization). Finally, two examples employed to...
