Previous studies reported that language comprehenders tend to preserve the initial incorrect analysis with temporarily ambiguous sentences following structural reanalysis (Christianson et al., 2001; van Gompel et al., 2006). One possible criticism is that the sentences tested in previous studies allow comprehenders to pragmatically infer that the initial misanalysis may be true. It is thus uncl...
in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
The accretion of ice in the compression system of commercial gas turbine engines operating in high ice water content conditions is a safety issue being studied by the aviation community. While most of the research focuses on the underlying physics of ice accretion and the meteorological conditions in which accretion can occur, a systems-level perspective on the topic lends itself to potential n...
BACKGROUND Quantitative relations between weather variables and malaria vector can enable pro-active control through meteorological monitoring. Such relations are also critical for reliable projections in a changing climate, especially since the vector abundance depends on a combination of weather variables, each in a given range. Further, such models need to be region-specific as vector popula...
The University of Alabama-Huntsville (UAH) and National Space Science and Technology Center (NSSTC) C-band Doppler weather radar was recently upgraded to dual-polarimetric capabilities. The upgraded radar is called ARMOR (Advanced Radar for Meteorological and Operational Research) and operates within the UAH/NSSTC STORMnet (Severe Thunderstorm Observations and Research Meteorological network). ...
Pregnancy and birth outcomes have been found to be sensitive to meteorological variation, yet few studies explore this relationship in sub-Saharan Africa where infant mortality rates are the highest in the world. We address this research gap by examining the association between meteorological factors and birth weight in a rural population in southwestern Uganda. Our study included hospital birt...
The relationship between nucleation events and numerous physical and meteorological parameters was analysed using data collected at the Station for Measuring Forest Ecosystem-Atmosphere Relations (SMEAR II) in Hyytiälä, Finland. To do this, measurements of solar radiation (ultraviolet [UV], global, photosynthetically active radiation [PAR], net, reflected global radiation and reflected PAR), ga...
This study evaluates the ability of the JULES land surface model (LSM) to simulate photosynthesis using local and global data sets at 12 FLUXNET sites. Model parameters include site-specific (local) values for each flux tower site and the default parameters used in the Hadley Centre Global Environmental Model (HadGEM) climate model. Firstly, gross primary productivity (GPP) estimates from drivi...
Estimates of CO2 fluxes that are based on atmospheric measurements rely upon a meteorology model to simulate atmospheric transport. These models provide a quantitative link between the surface fluxes and CO2 measurements taken downwind. Errors in the meteorology can therefore cause errors in the estimated CO2 fluxes. Meteorology errors that correlate or covary across time and/or space are parti...
The most significant and influential meteorological element in environmental conditions human activities is precipitation. objective of this study was to adjust eight probability distributions monthly, seasonal annual rainfall data the Pantanal Mato Grosso do Sul, Brazil, using a time series (1983-2013) by National Meteorological Water Agency (ANA). performance evaluation different distribution...
