Concrete, as the most widely used construction material, is associated with a high environmental impact. Within present study, structural optimization method of choice to counter this issue. The entire process, from optimization, design, experiments and numerical simulation outlined. Embedded in framework design competition (Concrete Girder Optimization Competition 2021), bridge between enginee...

the effect of magnetic field on the liquid-liquid equilibrium of two ternary systems (water + acetic acid + butyl acetate and water + acetic acid + dimethyl succinate) at 298.15 k under atmospheric pressure was investigated. the results obtained show that the strength of the magnetic field (0.02 t) affects the solubility of acetic acid in the used organic solvents. distribution coefficients and...

Abstract Structural optimization within concrete construction has been increasingly taken up in research the last two decades. Possible drivers are need for material-reduced and thus resource-efficient structures as well recent advancements automated construction. However, structural is characterized by nonlinear material behavior. Consequently, merge of design topology not trivial. This paper ...

BACKGROUND Lack of re-endothelialization and neointimal coverage on stent struts has been put forward as the main underlying mechanism leading to late stent thrombosis. Incomplete stent apposition (ISA) has been observed frequently in patients with very late stent thrombosis after drug eluting stent implantation, suggesting a role of ISA in the pathogenesis of this adverse event. The aim of thi...

The influence of the in-stream pylon and strut on the performance of scramjet combustor was experimentally and numerically investigated. The experiments were conducted with a direct-connect supersonic model combustor equipped with multiple cavities. The entrance parameter of combustor corresponds to scramjet flight Mach number 4.0 with a total temperature of 947 K. The research results show tha...

Given a lattice Λ ⊂ R, a cylinder anchored at two lattice points is called a strut (or Λ-strut to be precise) if its interior does not contain a lattice point. We are interested in determining the maximum radius for a strut of given length. Optimal Z-struts are constructed for n = 3, 4. We also derive, through a non-constructive but elementary argument, an achievable upper bound on the product ...

Liquid-Liquid equilibrium data for the (water + Lactic acid + 2-ethy-1-hexanol) ternary system in T=298.2K and P=1atm were determined and tie- lines related to equilibrium data has been drawn in the phases diagram . The reliability of the experimental tie-line data for this system was as confirmed by using the Hand and Othmer –Tobias correlations. The tie-line data were correlated by means of t...

The roll center is one of the key parameters for designing a suspension. Several driving characteristics are affected significantly by the migration of the roll center during the suspension’s motion. The strut/SLA (strut/short-long-arm) suspension, which is widely used in production cars, combines the space-saving characteristics of a MacPherson strut suspension with some of the preferred handl...

AIM Percutaneous coronary intervention (PCI) for severe calcified lesions is still challenging, and there are few studies of drug-eluting stent (DES) implantation for severe calcified lesions, especially regarding long-term results and hemodialysis patients. The study purpose was to clarify the factors, including DES strut thickness, that affect the long-term outcome of severe calcified lesion ...
