What is an adequate sample size? Operationalising data saturation for theory-based interview studies [PDF]

open access: yes, 2010
In interview studies, sample size is often justified by interviewing participants until reaching “data saturation”. However, there is no agreed method of establishing this.

Investigating the driver’s response time at signalized intersections

open access: yesTransport, 2018
It is generally accepted that, behavioural variables may show differences in different countries, and sometimes in different regions depending on cultural and other socio-economic factors.

Saturation flow versus green time at two‐stage signal controlled intersections [PDF]

open access: yesTransport, 2009
Intersections are the key components of road networks considerably affecting capacity. As flow levels and experience have increased over the years, methods and means have been developed to cope with growing demand for traffic at road junctions.

The saturation equation - an analytical expression for partial saturation during wicking flow in paper microfluidic channels [PDF]

open access: yes
The design and fabrication of paper based microfluidic devices is critically dependent on modelling fluid flow through porous paper membranes. A commonly observed phenomenon is partial saturation, i.e., regions of the paper membrane not being filled ...

Flow Boiling Heat Transfer of R134a in a Horizontal Smooth Tube: Experimental Results, Flow Patterns, and Assessment of Correlations

open access: yesEnergies, 2022
This study presents an extensive evaluation of heat transfer characteristics, flow patterns, and pressure drop for saturation pressures ranging from 460–660 kPa in a horizontal smooth tube of 5 mm internal diameter using R134a as the working fluid.

The Influence of Driver Behavior on Saturation Flow Rate at Signalized Intersection

open access: yesSulaimani Journal for Engineering Sciences, 2019
Signalized intersection is very critical and significant element of city traffic network. It has an affect on the road network as it significantly affects the performance of the whole network. The signalized intersection performance is usually

A Mixed-Flow Cellular Automaton Model for Vehicle Nonstrict Priority Give-Way Behavior at Crosswalks

open access: yesJournal of Advanced Transportation, 2020
The vehicle nonstrict priority give-way behavior (VNPGWB) is a common part of traffic interaction between motorized and nonmotorized vehicles in many countries. This study proposes a mixed-flow cellular automaton model to simulate the passing of vehicles

A steady-state saturation model to determine the subsurface travel time (STT) in complex hillslopes [PDF]

open access: yesHydrology and Earth System Sciences, 2010
The travel time of subsurface flow in complex hillslopes (hillslopes with different plan shape and profile curvature) is an important parameter in predicting the subsurface flow in catchments.

Gain saturation in gas flow and chemical lasers

open access: yes, 1985
A theoretical model for gain saturation in gas flow and chemical lasers is presented. The theory is applicable to all possible numerical values of τ/τc, where τ is the characteristie flow time for the flowing gas to move across the laser action region ...

The saturation flow volume as a function of the intersection passing speed [PDF]

open access: yesTransport Problems, 2013
Different methods of calculating the saturation flow volume were examined. It was found that none of them considers the speed of vehicles passing through the intersection (intersection passing speed).
