an experimental study was carried out on the wake of a cylinder on the back of which a plate is installed parallel to the fluid flow, with different terminal angles, where the reynolds number is 50000. at the end of the plate, blades with the height of 0.25 equal to the cylinder diameter and with 45, 90 and 135 degrees angle from the horizon, are installed where the cylinder diameter is equal t...

present for the formation mechanism. A famous •gPfeffer's semi-permeable membrane•h made of potassium ferrocyanide and copper sulfate in unglazed pottery cylinder by W. Pfeffer in 1877 is quite different from an artificial semi-permeable membrane at present, which is organized only by handling of extending high molecular substances, that is, collodium, cellophane, and various synthetic resins. ...

In the semi-classical limit the quantum mechanics of a stationary beam of counter-streaming relativistic electrons and ions is described by a nonlinear system of finite-temperature Thomas–Fermi equations. In the high temperature / low density limit these Thomas–Fermi equations reduce to the (semi-)conformal system of Bennett equations discussed earlier by Lebowitz and the author. With the help ...

In the semi-classical limit the relativistic quantum mechanics of a stationary beam of counter-streaming (negatively charged) electrons and one species of positively charged ions is described by a nonlinear system of finite-temperature Thomas–Fermi equations. In the high temperature / low density limit these Thomas–Fermi equations reduce to the (semi-)conformal system of Bennett equations discu...

Sedimentation in reservoirs is an important issue that should be considered for the reservoirs operation and useful life. In this study, application of the Adaptive Neuro-Fuzzy Inference System (ANFIS) and Artificial Neural Network (ANN) in prediction of the sediment release from the bottom outlet using semi-cylinder for different variables was evaluated. Dimensionless parameters such as dimens...

In this paper we define infinite-dimensional algebra and its representation, whose basis is naturally identified with semi-infinite configurations of the square ladder model (square lattice two lines). All these lead to representation N=2 algebra. We also extrapolate ideas for 3-leg triangular on cylinder.

Let $\mathcal{F}$ and $\mathcal{K}$ be commuting $C^\infty$ diffeomorphisms of the cylinder $\mathbb{T}\times\mathbb{R}$ that are, respectively, close to $\mathcal{F}_0 (x, y)=(x+\omega(y), y)$ $T_\alpha y)=(x+\alpha, y)$, where $\omega(y)$ is non-degenerate $\alpha$ Diophantine. Using KAM iterative scheme for group action we show are simultaneously $C^\infty$-linearizable if has intersection p...
