Laboratory Determination of Average Shear Stress in Smooth Rectangular and Trapezoidal Open Channels by Direct Method [PDF]

open access: yesعلوم و مهندسی آبیاری, 2016
Aim of this study is to measure shear stress in smooth rectangular and trapezoidal open channels. A new approach is presented to measure direct shear on wet perimeter of open channels.  A water flume with a section on a frictionless support (called knife

A direct method for analyzing the vertical vehicle-structure interaction [PDF]

open access: yes, 2011
A new method for the dynamic analysis of the vertical vehicle-structure interaction is presented. The vehicle and structure systems can be discretized with various types of finite elements and may have any degree of complexity.

An Indirect Method for an Alternate Perspective to Dispersion Diagrams of Magnetoinductive Waveguides

open access: yesIEEE Open Journal of Antennas and Propagation, 2022
The dispersion equation of magnetoinductive waveguides (MIWs) is traditionally solved directly for the propagation constant ( $\gamma $ ) to obtain diagrams for the attenuation ( $\alpha $ ) and phase ( $\beta $ ) constants vs.

Non‐linear dynamic soil‐structure interaction analysis of buildings

open access: yesTechnological and Economic Development of Economy, 2007
The objective of this research is to evaluate the effects of soil‐structure interaction (SSI) on the modal characteristics and on the dynamic response of structures. The stress had an impact on the overall behaviour of five storeys reinforced concrete (R/

A Direct Method for Photoacoustic Tomography with Inhomogeneous Sound Speed [PDF]

open access: yes, 2015
The standard approach for photoacoustic imaging with variable speed of sound is time reversal, which consists in solving a well-posed final-boundary value problem for the wave equation backwards in time.
