Numerical Analysis of the Effect of Cavitation on the Tip Leakage Vortex in an Axial-Flow Pump
Journal of Marine Science and Engineering, 2021 To understand the effect of cavitation on the tip leakage vortex (TLV), turbulent cavitating flows were numerically investigated using the shear-stress transport (SST) k–ω turbulence model and the Zwart–Gerber–Belamri cavitation model.

Macroscopic Loop Amplitudes in Two-Dimensional Dilaton Gravity
, 1993 Macroscopic loop amplitudes are obtained for the dilation gravity in two-dimensions. The dependence on the macroscopic loop length $l$ is completely determined by using the Wheeler-DeWitt equation in the mini-superspace approximation.

Dilation Equations with Exponential Decay Coefficients
Journal of Mathematical Analysis and Applications, 1999 Dilation equations with finitely many nonzero coefficients have been extensively studied because of their connection with compactly supported wavelets . However, some properties required in applications are not compatible with the compactness of the support. For example, \textit{X.-G. Xia} [J. Fourier Anal. Appl. 1, No. 2, 193-199 (1994; MR 96i:42026)]

Methods of solving dilation equations [PDF]
, 1992 A wavelet basis is an orthonormal basis for L2(ℜ), the space of squareintegrable functions on the real line, of the form {gnkn,k∈z, where gnk (t) = 2n/2 g (2nt−k) and g is a single fixed function, the wavelet Each multiresolution analysis for L2(ℜ) determines such a basis. To find a multiresolution analysis, one can begin with a dilation equation f (t)

A Class of Dilation Integral Equations
Journal of Mathematics Research, 2012 We present a class of dilation integral equations. The equations in this class depend on a dilation parameter $a\in\mathbb{R}.$ The existence of non trivial solutions in $L^1(\mathbb{R})$ is studied as a function of the dilation parameter. The main result establishes the non existence of these solutions for $|a| 1,$ and sufficient conditions for these ...

Mechanisms of parasite‐mediated disruption of brain vessels
FEBS Letters, EarlyView.Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

Group analysis of the Novikov equation [PDF]
, 2012 We find the Lie point symmetries of the Novikov equation and demonstrate that it is strictly self-adjoint. Using the self-adjointness and the recent technique for constructing conserved vectors associated with symmetries of differential equations, we ...

Dilation equations and Markov operators
Journal of Mathematical Analysis and Applications, 2005 Using the theory of Markov operators \(P: L^1(X)\to L^1(X)\) with \(P\) linear, \(\| Pf\|_1=\| f\|_1= 1\) for \(f\geq 0\), \(f\in L^1(X)\), the author gives a new proof for the following Theorem. Let \(N,k> 1\) be positive integers and \(c_0,\dots, c_N\geq 0\) be reals such that \(\sum^\infty_{i=0} c_{ki+j}= 1\) for every \(j\in \{0,\dots,k- 1 ...
