Perceptibility of double-slope reverberation decays

The Journal of the Acoustical Society of America, 2002
No concert hall has a perfectly diffuse field, although many are close enough that their decay is perceived as linear. In recent years, concert hall acousticians have taken steps to ensure more exaggerated double-sloped (nonlinear) decays in their concert halls by using coupled volumes.

Transient analysis of a double slope-double basin solar distiller

Energy Conversion and Management, 1991
Abstract In this communication, a transient analysis of a double slope-double basin solar still has been presented by incorporating the effects of water mass in the upper and lower basin, initial temperature of water in the lower basin, temperature dependent evaporative heat transfer coefficient, etc.

Theoretical and experimental investigation on double basin double slope solar still

Desalination, 2013
Abstract This paper presents a theoretical and experimental work performed on a double slope single basin and double basin solar still. In this work, an additional basin is incorporated with conventional single basin still to improve the performance of the double slope solar still. Single basin and double basin double slope stills are fabricated with

A new double reduction method for slope stability analysis

Journal of Central South University, 2014
The core of strength reduction method (SRM) involves finding a critical strength curve that happens to make the slope globally fail and a definition of factor of safety (FOS). A new double reduction method, including a detailed calculation procedure and a definition of FOS for slope stability was developed based on the understanding of SRM.

Double-Slope Method for Pumping Test Analysis

Journal of the Irrigation and Drainage Division, 1965
A new graphical method is outlined for analyzing the pumping test data for determining the hydraulic properties of aquifers, namely, the transmissivity, storativity, and leakage coefficient. Four different flow systems are considered. They are the nonsteady state of radial flow, one-dimensional flow of constant head or discharge, and of leaky artesian ...

Double-diffusive instabilities at a sloping boundary

Journal of Fluid Mechanics, 1991
When a body of fluid with a vertical salinity and temperature gradient is bounded by a sloping boundary, convective instabilities are often observed. These can occur if the fluid is subjected to heating or the addition of solute at the boundary, or if the boundary is an insulator.

Slope Angle Influence on the Seismic Wave Amplification Effect in a Double-sided Slope

2010
Slope angle significantly influences the seismic dynamic amplification effect of slope body. This paper carried out elasto-plastic dynamic finite element analysis on a double-sided slope and studied the influence pattern of slope angles upon dynamic amplification effect of seismic wave.

Characteristic equation of double slope passive solar still

Desalination, 2011
Abstract In this paper, a new approach has been made to obtain the characteristic equation of a double slope passive solar still (DSPSS) based on experimental observations. The performance of DSPSS has been analyzed for the composite climatic condition of New Delhi, India.

Double slope-assisted Brillouin optical correlation domain analysis

2017 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC), 2017
Fiber-optic Brillouin sensors for temperature and strain distributed monitoring offer unique performance in terms of distance, high spatial resolution and accuracy. Most of the available systems rely on Brillouin Optical Time-Domain Analysis (BOTDA) techniques, which employ pulsed pump signals guaranteeing a spatial resolution fundamentally limited to ...
