Cylindrical and semi-cylindrical weirs are used in water distribution systems for flow measurement in open channels and for control of water surface. Review of literature shows that cylindrical and semi-cylindrical weirs are not widely used in practice. Because of their low construction cost and simplicity, an investigation was done to study cylindrical and semi-cylindrical weirs in terms of th...
The aim of this work is to perform a detailed analysis the cracks paths obtained in fretting fatigue tests with cylindrical contact but taking into account presence an unavoidable (due device’s stiffness) small oscillatory rolling. In order obtain crack surfaces were measured confocal microscope after tests. Besides, area and surface initiation location by means optical microscope. measurements...
The authors construct a mechanical analog of an Ising antiferromagnet by inserting square array locally dilated sites into 2D crystalline membrane. Past buckling threshold, these dilations become bistable, and buckle either above or below the host lattice. When lattice is planar, neighboring prefer to be antialigned, but cylindrical can bias away from center curvature. They show that curvature ...
Optical devices and artificial photonic materials frequently make use of periodic arrangements identical scatterers in 3D, 2D, 1D, e.g. crystals, meta-surfaces, or particle chains. To simplify their analysis, we present here a computational framework based on the T-matrix method that explicitly exploits spherical, cylindrical, plane waves depending geometry number dimensions lattice. Due to ana...
This report introduces QEPCAD B, a program for computing with real algebraic sets using cylindrical algebraic decomposition (CAD). QEPCAD B both extends and improves upon the QEPCAD system for quantifier elimination by partial cylindrical algebraic decomposition written by Hoon Hong in the early 1990s. This paper briefly discusses some of the improvements in the implementation of CAD and quanti...

Planning and design procedure of an open pit mining project just can be started after ultimate pit determination. In the carried out study in this paper it was shown that the most important factor in ultimate pit determination and in consequence in the whole planning and design procedure of an open pit mine is the metal price. Metal price fluctuations in recent years were exaggerated and impose...
We study a low-energy effective field theory (EFT) describing the NN system in which all exchanged particles are integrated out. We show that fitting the residue of the S1 amplitude at the deuteron pole, rather than the S1 effective range, dramatically improves the convergence of deuteron observables in this theory. Reproducing the residue ensures that the tail of the deuteron wave function, wh...
