A Compact Driving Simulator To Support Research And Training Needs - Hardware, Software, And Assessment, Qimin Yao Aug 2015

A Compact Driving Simulator To Support Research And Training Needs - Hardware, Software, And Assessment, Qimin Yao

All Theses

In 2009, there were 10.8 million automotive crashes in the United States. When reviewing these incidents, young drivers were the over-represented group who were involved in these vehicular crashes. One reason that these young drivers have such high crash rates is that they often do not possess extensive driving knowledge and typically lack driving experience. Over the past three decades, researchers have investigated the driver training process which includes the classroom and behind the wheel to help address teaching the deficiencies in the driver education program. To complement the current driver education process, automotive simulators can be utilized to teach …


Feeling For Failure: Haptic Force Perception Of Soft Tissue Constraints In A Simulated Minimally Invasive Surgery Task, Lindsay Long Aug 2013

Feeling For Failure: Haptic Force Perception Of Soft Tissue Constraints In A Simulated Minimally Invasive Surgery Task, Lindsay Long

All Dissertations

In minimally invasive surgery (MIS), the ability to accurately interpret haptic information and apply appropriate force magnitudes onto soft tissue is critical for minimizing bodily trauma. Force perception in MIS is a dynamic process in which the surgeon's administration of force onto tissue results in useful perceptual information which guides further haptic interaction and it is hypothesized that the compliant nature of soft tissue during force application provides biomechanical information denoting tissue failure. Specifically, the perceptual relationship between applied force and material deformation rate specifies the distance remaining until structural capacity will fail, or indicates Distance-to-Break (DTB). Two experiments explored …


'Transfer Effect Study Of A Virtual Borescope In Training Aircraft Maintenance Technicians', Melissa Dorlette Paul May 2010

'Transfer Effect Study Of A Virtual Borescope In Training Aircraft Maintenance Technicians', Melissa Dorlette Paul

All Theses

The Federal Aviation Administration (FAA) has acknowledged training as an important tactic to improve the trustworthiness of inspection. This study was conducted to test the transfer of the skills learned with a simulator into the real world. For this purpose, data from seventeen students in the AMT program of Greenville Technical College was analyzed. Objective data was taken to assess the group's performance on the simulator after each session of training. The comparison between two groups was made using objective data, collected while the subjects went through a test on a real engine and using the real borescope, and subjective …


A Scanpath Comparison Of The Salient Features Of Weather Among General Aviation Pilots Based On Training And Experience, Michael Sawyer Dec 2009

A Scanpath Comparison Of The Salient Features Of Weather Among General Aviation Pilots Based On Training And Experience, Michael Sawyer

All Dissertations

Over the last 20 years the number of annual accidents in general aviation has seen a steady decline. The annual number of fatal accidents, however, has remained relatively stable. Adverse weather is consistently cited as a leading cause of fatal accidents in general aviation; weather accidents have a fatality rate nearly four times that of other general aviation accidents. Reviews of accident data reveal that often these accidents occur when inexperienced pilots who are certified only for visual flight rules flight continue into adverse weather. The Situation Assessment Hypothesis suggests these accidents occur when pilots fail to accurately recognize weather …


Investigation Of Training Algorithms For Hidden Markov Models Applied To Automatic Speech Recognition, Eric Fang May 2009

Investigation Of Training Algorithms For Hidden Markov Models Applied To Automatic Speech Recognition, Eric Fang

All Theses

The work presented in this thesis focuses on simulating a speech recognizer which is trained by different people with different speaking styles and investigates how sensitive the training and recognition processes are to the variations in the training data. There are four main parts to this work. The first involves an experiment of weighting methods for training with multiple observation sequences. The second involves the testing of different initial parameters. The third part includes the first experiment involving training with multiple observation sequences. The model's sensitivity to variations in training data was evaluated by comparing the cases of different values …
