Abstract This study investigates the seismic performance of a composite structure comprising cold-formed steel and high-strength concrete. Four short shear walls composed concrete, namely, one specimen without diagonal bracing, with angle-steel two lattice were designed for testing their low cyclic loading. The cracking load, ultimate displacement, maximum horizontal bearing capacity, failure p...

A simultaneous partition experiment of divalent metal ions was performed between sphalerite and 1 mol/L (Ni, Mg, Co, Fe, Mn)Cl2 aqueous solution under supercritical hydrothermal conditions 500–800 °C 100 MPa. The bulk coefficient that defined by KPB(ZnS) = (xMeS/xZnS)/(mMeaq/mZnaq) followed the order Zn ? Co Ni > Fe Mn Mg at all temperatures. In versus ionic radius (PC–IR) diagrams with loga...

Existing studies on surface deformation prediction consider single soil layers and straight-line excavation when investigating caused by metro shield construction. In this study, we provide a new method for studying the curved tunnel construction in upper soft lower hard soil. The equations are derived using Mindlin solution random medium theory verified engineering examples numerical simulatio...

This paper studies a flight load test method for helicopter blade, including the structural force of strain gauge bridge modification, calibration and establishment equation in typical maneuvers. First, blade structure was analyzed gauges were pasted profile which considered to be important positions analysis safe helicopter. Second, Load equations obtained by ground test, would used convert ti...

This work presents a novel surface matching and registration method based on the landmark curve-driven canonical surface quasiconformal mapping, where an open genus zero surface decorated with landmark curves is mapped to a canonical domain with horizontal or vertical straight segments and the local shapes are preserved as much as possible. The key idea of the canonical mapping is to minimize t...

This paper presents eecient algorithms for approximating a curve by a polygonal chain with vertices on a grid. We are given an x-monotone curve y = f(x) consisting of N pieces on some mn grid. Our goal is to compute an approximation of the given curve by an x-monotone polygonal chain whose vertices are points of the grid. For that, we discuss several optimization criteria such as minimizing the...

BACKGROUND The sniffing position is often considered optimal for direct laryngoscopy. Another concept of airway configuration involving a laryngeal vestibule axis and two curves has also been suggested. We investigated whether this theory can be supported mathematically and if it supports the sniffing position as being optimal for direct laryngoscopy. METHODS Magnetic resonance imaging scans ...

We evaluated the role of the sodium/glutamate transporter at the synaptic terminals of cone photoreceptors in controlling postsynaptic response kinetics. The strategy was to measure the changes in horizontal cell response rate induced by blocking transporter uptake in cones with dihydrokainate (DHK). DHK was chosen as the uptake blocker because, as we show through autoradiographic uptake measur...

Marrow transplantation from a syngeneic (monozygous twin) or allogeneic [homologous leucocytic antibody (HLA)-identical sibling] donor allows the administration of aggressive antileukemic therapy without regard to marrow toxicity. Until 1975 marrow transplantation was carried out only in patients with advanced relapse after failure of all other therapy. Six of sixteen patients given syngeneic m...
