Image Quality Analysis Using Glcm, Dhanashree Gadkari Jan 2004

Image Quality Analysis Using Glcm, Dhanashree Gadkari

Electronic Theses and Dissertations

Gray level co-occurrence matrix has proven to be a powerful basis for use in texture classification. Various textural parameters calculated from the gray level co-occurrence matrix help understand the details about the overall image content. The aim of this research is to investigate the use of the gray level co-occurrence matrix technique as an absolute image quality metric. The underlying hypothesis is that image quality can be determined by a comparative process in which a sequence of images is compared to each other to determine the point of diminishing returns. An attempt is made to study whether the curve of …

Effects Of Voluntary Control On Performance Response Under Stress., Christina Shawn Morris Jan 2004

Effects Of Voluntary Control On Performance Response Under Stress., Christina Shawn Morris

Electronic Theses and Dissertations

Recent stressful environments within military and non-military domains are producing a new challenge for the lab-based study of stress on task performance, one that requires knowledge of underlying cognitive-motivational and goal orientation factors. Results of recent stress on task performance research traditionally employ metaphorical explanations (i.e., resource theory) in order to rapidly apply stimulus-response outcomes to the real world counterparts. This dissertation provides an alternative perspective about these metaphorical, or black box, interpretations and reveals how they may be confounded with respect to the intended real world counterpart. To examine how voluntary human control can influence traditional stress/no-stress research findings, …

Communication Modality And After Action Review Performance In A Distributed Immersive Virtual Environment, Jason P. Kring Jan 2004

Communication Modality And After Action Review Performance In A Distributed Immersive Virtual Environment, Jason P. Kring

Electronic Theses and Dissertations

Technological innovations in data transfer and communication have given rise to the virtual team where geographically separate individuals interact via one or more technologies to combine efforts on a collective activity. In military, business, and spaceflight settings, virtual teams are increasingly used in training and operational activities; however there are important differences between these virtual collaborations and more traditional face-to-face (FTF) interactions. One concern is the absence of FTF contact may alter team communication and cooperation and subsequently affect overall team performance. The present research examined this issue with a specific focus on how communication modality influences team learning and …

A Holistic Model Of The Interplay Of Parent-Adolescent Interaction Varialbes: Outcomes As A Result Of Conflictual Processes, Cliff Blake Mckinney Jan 2004

A Holistic Model Of The Interplay Of Parent-Adolescent Interaction Varialbes: Outcomes As A Result Of Conflictual Processes, Cliff Blake Mckinney

Electronic Theses and Dissertations

Many variables have been analyzed in order to understand parent-adolescent interactions and outcomes for adolescents. These variables must be integrated into a model that demonstrates the holistic interplay of parent-adolescent interaction variables so that a more comprehensive understanding of parent-adolescent interactions is achieved. Variables included in the model proposed here were parenting, family environment, expectations, conflict, and outcomes. Parenting, family environment, and conflict were associated with outcomes for adolescents. When the variables were analyzed simultaneously with structural equation modeling, however, the relationship of parenting and adolescent outcomes was mediated wholly for male-father, male-mother, and female-father relationships but remained significant for …

Cell Phone Distraction Analysis Of Motor Response In A Simulated Driving Environment, Anusha Ravishankar Jan 2004

Cell Phone Distraction Analysis Of Motor Response In A Simulated Driving Environment, Anusha Ravishankar

Electronic Theses and Dissertations

Does the use of a cell phone while driving influence the driver's ability to execute a proper turn? Is there difference between genders pertaining to motor skill while driving in a simulated driving environment? To accomplish this task, three groups of ten participants (5 women and 5 men) each were tested using a scripted test scenario focusing on left and right turns. The participants were made to drive through a test scenario to get used to the driving simulator. The scenario for the experimental group was an inner-city training scenario with the presence of vehicular traffic and the main focus …

The Effects Of Differential Item Functioning On Predictive Bias, Damon Bryant Jan 2004

The Effects Of Differential Item Functioning On Predictive Bias, Damon Bryant

Electronic Theses and Dissertations

The purpose of this research was to investigate the relation between measurement bias at the item level (differential item functioning, dif) and predictive bias at the test score level. Dif was defined as a difference in the probability of getting a test item correct for examinees with the same ability but from different subgroups. Predictive bias was defined as a difference in subgroup regression intercepts and/or slopes in predicting a criterion. Data were simulated by computer. Two hypothetical subgroups (a reference group and a focal group) were used. The predictor was a composite score on a dimensionally complex test with …

Transforming Learning Into A Constructive Cognitive And Metacognitive, Haydee Cuevas Jan 2004

Transforming Learning Into A Constructive Cognitive And Metacognitive, Haydee Cuevas

Electronic Theses and Dissertations

This study explored the effectiveness of embedding a guided, learner-generated instructional strategy (query method), designed to support learners' cognitive and metacognitive processes, within the context of a computer-based complex task training environment (i.e., principles of flight in the aviation domain). The queries were presented as "stop and think" exercises in an open-ended question format that asked learners to generate either simple (low-level elaboration) or complex (high-level elaboration) sentences from a list of key training concepts. Results consistently highlighted the benefit of presenting participants with low-level elaboration queries, as compared to the no-query or high-level elaboration queries. In terms of post-training …

Improving Metacomprehension And Learning Through Graduated Concept Mod, Eleni Kring Jan 2004

Improving Metacomprehension And Learning Through Graduated Concept Mod, Eleni Kring

Electronic Theses and Dissertations

Mental model development, deeper levels of information processing, and elaboration are critical to learning. More so, individuals' metacomprehension accuracy is integral to making improvements to their knowledge base. In other words, without an accurate perception of their knowledge on a topic, learners may not know that knowledge gaps or misperceptions exist and, thus, would be less likely to correct them. Therefore, this study offered a dual-process approach that aimed at enhancing metacomprehension. One path aimed at advancing knowledge structure development and, thus, mental model development. The other focused on promoting a deeper level of information processing through processes like elaboration. …

An Investigation Into Providing Feedback To Users Of Decision Support, James Pharmer Jan 2004

An Investigation Into Providing Feedback To Users Of Decision Support, James Pharmer

Electronic Theses and Dissertations

Research in several domains has shown that the implementation of computerized decision support aids is often associated with issues of human-automation interaction, which can have disastrous consequences. One often-cited reason for these issues is the poor quality of the feedback that is provided to the operators through these tools. The objective of the proposed investigation is to examine how providing feedback through a decision support tool affects operator knowledge and performance in the context of a fault management task for naval gunfire support. A one-way between-groups comparison was made to investigate differences between providing decision support feedback (logic trace, mission …

The Effects Of Stimulus Motion On Contrast Sensitivity: Dynamic Sensi, Merrill Zavod Jan 2004

The Effects Of Stimulus Motion On Contrast Sensitivity: Dynamic Sensi, Merrill Zavod

Electronic Theses and Dissertations

Static Visual Acuity (SVA) has been called into question for some time as a measure of overall visual system function and as a predictor of performance on real-life tasks requiring vision (i.e., operating an automobile). Specifically, it has been pointed out that the targets employed in most SVA testing (high contrast, stationary letters) are an insufficient analog to actual targets encountered in everyday activities, which are often in motion and/or of less-than-perfect contrast. In addition, the size-threshold methodology typically used to measure SVA is incongruent with current theories of a multi-channel visual system. Dynamic Visual Acuity (DVA) and Contrast Sensitivity …

Tractor-Trailer Simulation And The Assessment Of Training Scenarios For City-Driving: Skill Building In The Area Of Left And Right Turns, James Whitmire Jan 2004

Tractor-Trailer Simulation And The Assessment Of Training Scenarios For City-Driving: Skill Building In The Area Of Left And Right Turns, James Whitmire

Electronic Theses and Dissertations

A simulated inner-city training scenario was found to increase skills in the area of turning when compared with a simulated off-track training scenario. To answer this question, two groups of ten participants (5 women and 5 men) were tested using three scripted scenarios focusing on left and right turns. The first training scenario (control group) is an off-track training scenario, which consists of a large asphalt lot and the use of orange cones; the second training scenario (experimental group) is an inner-city training scenario without the presence of vehicular traffic; and the third scenario (test scenario) is an inner-city scenario …
