Quand faire des gestes permet de mieux apprendre
(2010-09)Increasingly, research has demonstrated that gestures are a route into children’s unspoken thoughts. Encouraging children to gesture, therefore, may make their implicit understanding of a concept more explicit and bring ... -
Quand les mots sont des actes : les 'énoncés spontanés'chez Wittgenstein et la dissolution du problème corps-esprit'
(2005)According to Wittgenstein, our spontaneous utterances are not descriptions, but expressions more akin to behaviour than to language: a new sort of speech-act. Rather than conventional performatory words, spontaneous ... -
Quantification of nuclear uncertainties in nucleosynthesis of elements beyond Iron
(Proceedings of Science (PoS), 2015-07-11)Nucleosynthesis beyond Fe poses additional challenges not encountered when studying astrophysical processes involving light nuclei. Generally higher temperatures and nuclear level densities lead to stronger contributions ... -
Quantification of vehicle fleet PM10 particulate matter emission factors from exhaust and non-exhaust sources using tunnel measurement techniques
(2016-03-01)Road tunnels act like large laboratories; they provide an excellent environment to quantify atmospheric particles emission factors from exhaust and non-exhaust sources due to their known boundary conditions. Current work ... -
Quantified reasoning in formal specification : transfer of everyday errors and biases?
(University of Hertfordshire, 1997)Cognitive studies of syllogistic reasoning appear to provide important pointers to the ways in which people reason with quantified statements. Previous natural language based studies of the syllogistic task suggest that ... -
Quantifying acceptable mesh dependencies for computational investigations of airflows within rooms
(2002)Ignorance of mesh dependency can sometimes be an embarrassment in numerical calculations. Mesh structures need to be developed to eradicate mesh dependency without compromising the finite computing resource and/or incurring ... -
Quantifying AGN-Driven Metal-Enhanced Outflows in Chemodynamical Simulations
(2015-09-30)We show the effects of AGN-driven outflows on the ejection of heavy elements using our cosmological simulations, where super-massive black holes originate from the first stars. In the most massive galaxy, we have identified ... -
Quantifying bioaerosol concentrations in dust clouds through online UV-LIF and mass spectrometry measurements at the Cape Verde Atmospheric Observatory
(2020-11-28)Observations of the long-range transport of biological particles in the tropics via dust vectors are now seen as fundamental to the understanding of many global atmosphere–ocean biogeochemical cycles, changes in air quality, ... -
Quantifying effects of long-range transport of NO2 over Delhi using back trajectories and satellite data
(2024-01-19)Exposure to air pollution is a leading public health risk factor in India, especially over densely populated Delhi and the surrounding Indo-Gangetic Plain. During the post-monsoon seasons, the prevailing north-westerly ... -
Quantifying the association between habitual energy expenditure and blood pressure
(2000)Previous studies have demonstrated an association between physical inactivity and hypertension, but the methods used to assess activity have been subjective and imprecise. Recently methods have become available allowing ... -
Quantifying the imprint of a severe Hector thunderstorm during ACTIVE/SCOUT-O3 onto the water content in the upper troposphere/lower stratosphere
(2009)The development of a severe Hector thunderstorm that formed over the Tiwi Islands, north of Australia, during the Aerosol and Chemical Transport in Tropical Convection/Stratospheric-Climate Links with Emphasis on the Upper ... -
Quantifying the Risk to Health Care Workers of Cough as an Aerosol Generating Event in an Ambulance Setting: A Research Report
(2022-08-17)Introduction and Objective: United Kingdom Health Security Agency (UKHSA) guidance related to mask use for health care workers in a non-aerosol generating procedure (AGP) setting has remained as Level 2 water repellent ... -
Quantitative accuracy assessment of contextually filtered classified images
(2001)The use of post-classification contextual filters to increase the overall accuracy of classified remotely sensed imagery is a well known but under-used technique. Many practitioners have used a modal majority decision rule ... -
A Quantitative Analysis of Interfaces to Time-Triggered Communication Buses
(2021-04-28)Nodes connected to a time-triggered (TT) network can access the network interface in two different ways, synchronously or asynchronously, which greatly impacts communication timing and message lifespans (i.e., the time ... -
A Quantitative Analysis of TCP performance over Wireless Multihop Networks
(Institute of Electrical and Electronics Engineers (IEEE), 2001)An analytical model of a single TCP session based on a string topology in wireless multihop networks is presented. The model for the communication process also considers buffering, propagation delay and channel access ... -
A quantitative and qualitative analysis of factors affecting software process improvement
(2003)Despite the growing body of research on software process improvement (SPI), there is still a great deal of variability in the success of SPI programmes. In this paper, we explore 26 factors that potentially affect SPI. We ... -
Quantitative assessment of colorectal cancer tumor vascular parameters by using perfusion CT: influence of tumor region of interest
(2008)To prospectively determine whether position and size of tumor region of interest (ROI) influence estimates of colorectal cancer vascular parameters at computed tomography (CT). -
Quantitative Assessment of Damage in Composites by Implementing Acousto-Ultrasonics Technique
(2022-09-08)This study focused on quantitative damage severity assessment in composite materials using Acousto-Ultrasonics (AU), an in-service and active non-destructive inspection technique in which Lamb waves are communicated through ... -
Quantitative determination of single-bead metal content from a peptide combinatorial library
(2006-11-13)An electrothermal vaporizer inductively coupled plasma mass spectrometer (ETV-ICPMS) was used to quantitatively screen metals bound to single polystyrene (TentaGel) beads with immobilized oligopeptides. Tests were performed ...
