Abstract. Structural health monitoring (SHM) is often approached from a statistical pattern recognition or machine learning perspective with the aim of inferring state structure using data derived network sensors placed upon it. In this paper, two SHM sensor placement optimisation (SPO) strategies that offer robustness to environmental effects are developed and evaluated. The both involve const...

Recent demand on welding fluxes for high-strength low-alloy steel grades has necessitated the development of CaF2-free towards high heat input applications. To meet such requirements, a flux design strategy been postulated by varying MnO/(CaF2 + MnO) mass ratio in CaF2–SiO2–MnO system. The effect MnO substitution CaF2 viscosity and structure investigated, quantitative relationship between struc...

tati dialect of northern khorasan is one of the oldest dialects of ancient iran which has structural differences with its other variations. sharing common words with the other tati dialects, especially those of azerbaijan and ghazvin, shows that tati dialect of northern khorasan, like others, is one of the dialects existing in pre-islamic era. this dialect is also one of those dialects in which...
