Analysis of the wind tunnel test of a tilt rotor power force model
Two series of wind tunnel tests were made to determine performance, stability and control, and rotor wake interaction on the airframe, using a one-tenth scale powered force model of a tilt rotor aircraft. Testing covered hover (IGE/OCE), helicopter, conversion, and airplane flight configurations. Forces and moments were recorded for the model from predetermined trim attitudes. Control positions were adjusted to trim flight (one-g lift, pitching moment and drag zero) within the uncorrected test data balance accuracy. Pitch and yaw sweeps were made about the trim attitudes with the control held at the trimmed settings to determine the static stability characteristics. Tail on, tail off, rotors on, and rotors off configurations were testes to determine the rotor wake effects on the empennage. Results are presented and discussed
An exploration of self-determination theory in individual track and field Olympic medalists from the United States of America at the 2012 London Games
Dissertation supervisors: Dr. Alex Waigandt and Dr. Richard McGuire.Includes vita.The purpose of this study was to investigate the psychosocial aspects of the reported lived experience of Olympic medal winning athletes by the United States Track and Field athletes in the 2012 London Olympic Games, specifically focusing on an exploration of evidence of the elements of self-determination theory. This study utilized a qualitative approach and an interpretive phenomenological design to answer the research questions. Semi-structured interviews were used to obtain in-depth data about the three participant's lived experience of winning an Olympic medal at the 2012 Olympic games in London. These interviews were transcribed and significant statements were coded. The codes were then clustered to form subordinate and ultimately master level themes. The master level themes that emerged from the lived experience of all participants in the study were 1) Support, 2) Psychological Factors and 3) Motivation. Interpretive phenomenological analysis was used to compare the resultant themes of this study to the theoretical framework. This inductive process resulted in consistencies between the results of this study that and the pre-existing theoretical framework, thus supporting and strengthening self-determination and its sub-theory of organismic integration theory (Deci and Ryan, 1985). The results of this study are useful for athletes, coaches, sport leaders and anyone that is interested in performing their best leading up to and during their performance.Includes bibliographical references (pages 101-107)
The Conditional Lucas & Kanade Algorithm
The Lucas & Kanade (LK) algorithm is the method of choice for efficient dense
image and object alignment. The approach is efficient as it attempts to model
the connection between appearance and geometric displacement through a linear
relationship that assumes independence across pixel coordinates. A drawback of
the approach, however, is its generative nature. Specifically, its performance
is tightly coupled with how well the linear model can synthesize appearance
from geometric displacement, even though the alignment task itself is
associated with the inverse problem. In this paper, we present a new approach,
referred to as the Conditional LK algorithm, which: (i) directly learns linear
models that predict geometric displacement as a function of appearance, and
(ii) employs a novel strategy for ensuring that the generative pixel
independence assumption can still be taken advantage of. We demonstrate that
our approach exhibits superior performance to classical generative forms of the
LK algorithm. Furthermore, we demonstrate its comparable performance to
state-of-the-art methods such as the Supervised Descent Method with
substantially less training examples, as well as the unique ability to "swap"
geometric warp functions without having to retrain from scratch. Finally, from
a theoretical perspective, our approach hints at possible redundancies that
exist in current state-of-the-art methods for alignment that could be leveraged
in vision systems of the future.Comment: 17 pages, 11 figure
