Sensitivity of MEPDG Using Advanced Statistical Analyses
… pavement conditions. In this study, sensitivity analyses are performed to identify a list of input variables that have significant impacts on the MEPDG outputs considering New Mexico pavement conditions. Sensitivity analyses are performed in two steps. In the first step, a preliminary sensitivity …

Statistical analyses of gravitational microlensing probability densities
Gravitational microlensing is a powerful modelling tool, that is essential in accurately understanding the lensing behavior of astronomically strong lensed objects. Using Joachim Wambsganss micro-magnification maps, we discuss the creation of a Monte-Carlo tool that can determine the likelihood for …

Statistical analyses of extinction in the marine fossil record
… of marine invertebrates were investigated using statistical methods and familial diversity data. First, a series of analyses were performed to determine whether the magnitudes of mass extinctions were statistically distinguishable from the magnitudes of background extinctions. The expected …

Some Statistical Analyses of the Climate of Nacogdoches, Texas for Applications in Natural Resources Management
<p>Analyses of a variety of climatic variables generated from 80 years (1901-80) of daily precipitation and temperature data collected by the National Weather Service showed that Nacogdoches is characterized by a humid subtropical climate with an average annual precipitation and temperature of …

Statistical analyses of exoplanetary systems and individual studies of the atmospheres of two sub-Neptune-sized planets
With over 4000 exoplanets already confirmed and more to come through various surveys, efforts have been made to measure their population properties and to characterize individual planets in terms of their mass, temperature, atmosphere, and evolution history. In this thesis, I present research on …

Experimental and Statistical Analyses of the Effects of a Uniform Positive Pressure Applied to the Lower Limb in Humans on Vascular Haemodynamics
The determination of required pressure level to provide an optimum treatment is an important task for vascular clinicians. This thesis is a first investigation including both venous and arterial femoral velocities and distal microcirculation of the forefoot to evaluate the effects of varying …

Simulation of protected area and forestry cutblock design in the boreal plain ecoregion
Spatial and statistical analyses are becoming more commonplace in planning for conservation and land-use programs. I used specific spatial and statistical analyses to examine their potential for answering questions posed by stakeholders in the boreal plain ecoregion regarding the strategic …

Positive and Negative Interactions in Economic and Ecological Systems: An Analogical Approach
The results of the statistical analyses were used to structure a simulation model that combines explained variation with randomized fluctuations. The simulation model demonstrates also the lack of dependency effects between the industries. Possible reasons for these findings are discussed along …
