Engineering Science and Technology, an International JournalMasonry construction in cold regions is highly vulnerable to insufficient early-age curing, which can suppress mortar hydration and weaken the brick–mortar interface, ultimately reducing structural reliability.

RADAR LOCATION CONTRAST IN THE REFLECTION OF ELECTROMAGNETIC WAVE FROM TWO OBJECTS
Научный вестник МГТУ ГА, 2018 The paper considers the problem of finding the power flux density of signals reflected from two objects with different symmetric scattering matrices when they are irradiated with a completely polarized wave.

Remarks on non-diagonality conditions for Sierpinski carpets
Advanced Studies in Pure Mathematics, 2019 We prove the equivalence of three different formulations of non-diagonality for Sierpinski carpets given by Barlow, Bass, Kumagai and Teplyaev [5], by Hino [10] and by Kigami [12]. We also derive some geometric property of Sierpinski carpets from the non-diagonality.

A condition for diagonalization modulo arbitrary norm ideals
Journal of Functional Analysis, 2008 Let \(\mathcal C\) be a norm ideal and \((A_1, \dots,A_n)\) be a commuting tuple of self-adjoint operators on a separable Hilbert space \(\mathcal H\). Continuing previous investigations from a series of articles in the same journal, the author considers the problem of determining whether or not \((A_1,\dots,A_n)\) can be simultaneously diagonalized ...

Metoda quasi-Newton diagonală bazată pe minimizarea funcţiei Byrd-Nocedal pentru optimizare fără restricţii [PDF]
Revista Română de Informatică și Automatică, 2018 A new quasi-Newton method with a diagonal updating matrix is suggested, where the diagonal elements are determined by minimizing the measure function of Byrd and Nocedal subject to the weak secant equation of Dennis and Wolkowicz.

Stability of Matrix Polytopes with a Dominant Vertex and Implications for System Dynamics
Abstract and Applied Analysis, 2013 The paper considers the class of matrix polytopes with a dominant vertex and the class of uncertain dynamical systems defined in discrete time and continuous time, respectively, by such polytopes. We analyze the standard concept of stability in the sense

Moldavian Journal of the Physical Sciences, 2008 The off-resonance effect and its influence on the reversibility between two quantum subsystems (single mode cavity field and a three-level in cascade configuration) in interaction are studied.

Non-symmetric convergence and regularity
Applied General TopologyWe study regularity in quasi-convergence spaces and biconvergence spaces. We show that a notion weaker than the usually considered pairwise regularity is sufficient in important applications.

Isomorphism Identification of Planar Mechanism based on Assur-group Adjacency Matrix
Jixie chuandong, 2016 The isomorphism identification of structural type is a vital problem now. For dealing with the isomorphism generated in synthesis of planar configuration based on the synthesis method of Assur- group adjacency matrix,a methodology of Assur- group ...
