Climate sensitivity study with energy balance models
In this thesis, the sensitivity of the Earth's climate is studied by modeling past climatic variations with two-dimensional seasonal energy balance model. This thesis consists of two parts. The first part is a study of the interaction between the seasonal cycle and the small ice cap instability, …

Driving the ocean's overturning : an adjoint sensitivity study
The focus of this thesis is the sensitivity of the strength of the meridional overturning circulation to surface forcing and mixing on climatological time scales. An adjoint model is used to gain new insights into the spatial characteristics of the sensitivity patterns. Adjoint models provide the …

The Extinction Probabilities of Nuclear Assemblies: A Sensitivity Study
… of mathematical analysis techniques known as sensitivity analysis (and in particular, a theoretical construct known as the Gâteaux-variation) will be employed to calculate these effects. The analysis will be left as general as possible within the context of a clean, stochastic point …

Sensitivity study of turbulent flow simulations over a rotating disk
With increasing demand for renewable energy, there is a need for accurate and reliable simulations of a flow around a wind turbine. To be of use as an engineering design and planning tool, such simulations should be conducted in a timely manner. This can be achieved if a flow is modeled with …

Tavis Mining Highway Stability Study - Methods Overview and Sensitivity Study
This paper is a sensitivity study of highwall stability at Falkirk Mine. Since mining of the Tavis Creek will require maximizing the highwall height, this paper explores factors that influence the strength of the wall. The first part consists of a previous works review composed primarily of geology …

Frontal lobe asymmetry and impulsive aggression : a reinforcement sensitivity study.
The current study compared impulsive aggressive individuals and nonaggressive controls using frontal cortical EEG activity. Impulsive aggression is a reactive or emotionally charged violent response characterized by a loss of behavioral control. Previous physiological studies have found impulsive …

A sensitivity study on modeling hydrologic effects due to urbanization
… input parameters to the Watershed Model. This study was initiated to evaluate the ability of OPSET to reflect changes due to urbanization in the best-fit estimates of those watershed parameters which cannot be estimated from historical records or watershed characteristics. This study also …

Time-Lapse Depletion Modeling Sensitivity Study: Gas-Filled Gulf of Mexico Reservoir
Time-lapse seismic allows oil/gas reservoir monitoring during production, highlighting compaction and water movement. Time-lapse modeling, using a stress-dependent rock physics model, helps determine the need and frequency of expensive repeat seismic acquisition. We simulate a Gulf of Mexico gas …

Sensitivity Study on Modification of Vertical Distribution of Strength and Stiffness in Wood Shear Wall Building Models
This thesis presents a numerical study of the influence of varying story strength on the seismic performance of multi-story wood-frame shear wall buildings. In the prior FEMA P695 studies of these buildings, the non-simulated collapse limit-state was exceeded primarily in the first story. This …
