Manning's Formula and the Strickler Scaling Derived from a Co-spectral Budget Model
Gabriele Manoli, Sara Bonetti, Gabriel George Katul
Manning's empirical formula in conjunction with Strickler's scaling is widely used to predict the bulk velocity (V) from the hydraulic radius (Rh), the roughness size (r), and the slope of the energy grade line (S) in uniform channel flows at high bulk Rey ...
2023Chung-type law of the iterated logarithm and exact moduli of continuity for a class of anisotropic Gaussian random fields
We establish a Chung-type law of the iterated logarithm and the exact local and uniform moduli of continuity for a large class of anisotropic Gaussian random fields with a harmonizable-type integral representation and the property of strong local nondeterm ...
INT STATISTICAL INST2023The effects of Prandtl number on the nonlinear dynamics of Kelvin-Helmholtz instability in two dimensions
It is known that the pitchfork bifurcation of Kelvin-Helmholtz instability occurring at minimum gradient Richardson number Ri(m) similar or equal to 1/4 in viscous stratified shear flows can be subcritical or supercritical depending on the value of the Pra ...
2021Programmable Multistable Mechanisms: Design, modeling, characterization and applications
Mohamed Gamal Abdelrahman Ahmed Zanaty
Multistable Mechanisms are mechanical devices having more than one stable state. Since these mechanisms can maintain different deformations with zero force, they are advantageous for low power environments such as wristwatches and medical devices.
In this ...
EPFL2018Hardness Results for Consensus-Halving
Jie Zhang, Aris Filos Ratsikas
The Consensus-halving problem is the problem of dividing an object into two portions, such that each of n agents has equal valuation for the two portions. We study the epsilon-approximate version, which allows each agent to have an epsilon discrepancy on t ...
Schloss Dagstuhl-Leibniz-Zentrum fuer Informatik2018Mechanical oscillator
Simon Nessim Henein, Ilan Vardi, Mohammad Hussein Kahrobaiyan
wherein k1, k3, k5 . . . are constants and θ is an angle of inclination of said third axis (x, P) of said inertial body with respect to a direction of said third axis (xr) when said inertial body is in said resting position. ...
2018Using Structural Properties for Integer Programs
Integer programs (IPs) are one of the fundamental tools used to solve combinatorial problems in theory and practice. Understanding the structure of solutions of IPs is thus helpful to argue about the existence of solutions with a certain simple structure, ...
SPRINGER INTERNATIONAL PUBLISHING AG2018Manning’s formula and Strickler’s scaling explained by a co-spectral budget model
Sara Bonetti, Gabriel George Katul
Manning’s empirical formula in conjunction with Strickler’s scaling is widely used to predict the bulk velocity V from the hydraulic radius Rh, the roughness size r and the slope of the energy grade line S in uniform channel and pipe flows at high bulk Rey ...
2017Higher-order continuation method for the rigid-body kinematic design of compliant mechanisms
Simon Nessim Henein, Lennart Rubbert
Compliant mechanisms are of great interest in precision engineering. In this paper we propose a higher order continuation method to help their rigid-body kinematic design. The method helps to investigate the choice of a mechanism configuration through the ...
Elsevier2017Generalized Pickands constants and stationary max-stable processes
Pickands constants play a crucial role in the asymptotic theory of Gaussian processes. They are commonly defined as the limits of a sequence of expectations involving fractional Brownian motions and, as such, their exact value is often unknown. Recently, D ...
