Evaluating The Surface Layer Wind Profile In The Wrf, Robert Stephen James
Evaluating The Surface Layer Wind Profile In The Wrf, Robert Stephen James
Theses and Dissertations
The purpose of this thesis is to investigate how the surface vertical wind profile responds to different planetary boundary layer schemes in computer models. Local surface roughness is one of the elements represented in these schemes, and is used when interpolating winds down from the lowest model level to the surface, so this needs to be accurately represented in the model. Computer models rely on one bulk estimate of surface roughness for a given grid point, despite the complexity of surrounding terrain. Data for this research was gathered from local surface observations and computer simulations, which looked at two different …

Using Variations Of Shape And Appearance In Alignment Methods For Classifying Human Actions, Sultan Mohammad Almotairi
Theses and Dissertations
In this dissertation, we address the problem of recognizing human-action from videos. The recognition aims at recovering action information from the image sequences using different features such as variations of the human shape. Approaches based on such features often use sequence-alignment methods. We propose two novel methods for human-action recognition. We also propose an elliptical-shaped band for the Dynamic Time Warping (DTW) that provides a good compromise between alignment accuracy and computational speed. First, we study the applicability of the pairwise shape-similarity measurements for human-action recognition. Since action can be seen as a sequence of shapes of silhouette poses, there …

Distributed Gui Testing Of Ios Applications With Hadoopunit, Krissada Dechokul
Theses and Dissertations
Smartphones have become an important medium of communication for millions of people. They have come to expect high-quality mobile applications, which have increased the importance of software testing in modern software development. While software testing can ensure the quality of a system under test (SUT), it has suffered from lengthy execution time, especially for system-level GUI testing. In general, system-level GUI testing can be time-consuming because it requires walking through every user interface element and every possible variation that users could experience through the GUI of the application. In addition, this type of testing exercises the SUT from the outside …
