Hybrid Projectile Body Angle Estimation For Selectable Range Increase, Christopher J. Gioia
Hybrid Projectile Body Angle Estimation For Selectable Range Increase, Christopher J. Gioia
Graduate Theses, Dissertations, and Problem Reports (ETD)
A Hybrid Projectile (HP) is a tube launched munition that transforms into a gliding UAV, and is currently being researched at West Virginia University. A simple launch timer was first envisioned to control the transformation point in order to achieve maximum distance. However, this timer would need to be reprogrammed for any distance less than maximum range due to the nominal time to deployment varying with launch angle. A method was sought for automatic wing deployment that would not require reprogramming the round. A body angle estimation system was used to estimate the pitch of the HP relative to the …

The Diabetic Heart: Examination Of The Inner Mitochondrial Membrane, Tara Lyne Slider Croston
The Diabetic Heart: Examination Of The Inner Mitochondrial Membrane, Tara Lyne Slider Croston
Graduate Theses, Dissertations, and Problem Reports (ETD)
Cardiovascular complications, such as diabetic cardiomyopathy, are the primary cause of morbidity and mortality in patients with diabetes mellitus. The hyperglycemic environment associated with diabetes mellitus has been shown to induce the mitochondrial dysfunction contributing to diabetic cardiomyopathy. The examination of mitochondrial function is further complicated by the existence of two spatially and functionally distinct cardiac mitochondrial subpopulations, the subsarcolemmal (SSM) interfibrillar (IFM) mitochondria. These two pools of mitochondria respond differently to pathologic stimuli, such as diabetes mellitus. Targeted by the deleterious effects of diabetes mellitus, the inner mitochondrial membrane (IMM) is composed of a specific lipid environment that houses …

Temporal Expression Of Key Angioregulatory Proteins In Response To Exercise And Detraining, Sara A. Olenich
Temporal Expression Of Key Angioregulatory Proteins In Response To Exercise And Detraining, Sara A. Olenich
Graduate Theses, Dissertations, and Problem Reports (ETD)
Angiogenesis is an important adaptation to exercise, occurring in response to a multitude of different stimuli including: shear stress, mechanical stretch, ischemia, electrical stimulation, and exercise. Current thinking suggests skeletal muscle angiogenesis is a temporal process controlled by a balance between positive and negative angiogenic proteins. But there is limited information on what molecular mediators control skeletal muscle angiogenesis in this time line, creating a critical need to clarify how individual protein responses regulate physiologic skeletal muscle angiogenesis in response to exercise training and/or physical deconditioning. Our objective is to characterize the temporal expression of several key positive (VEGF, MMP-2, …
Adaptation Of Temporal Control To Unpredictable Mid-Session Changes In A Rapid-Acquisition Multiple Peak-Interval Procedure, Nathaniel Rice
Adaptation Of Temporal Control To Unpredictable Mid-Session Changes In A Rapid-Acquisition Multiple Peak-Interval Procedure, Nathaniel Rice
Graduate Theses, Dissertations, and Problem Reports (ETD)
The temporal arrangement of events is important in laboratory and real-world settings. Many real-world scenarios are highly dynamic and not reflected by the steady-state nature of experiments often conducted in laboratory settings. To address the dynamic nature of the environment, four pigeons responded on a rapid-acquisition multiple peak-interval schedule. Peak-interval trials, extinction trials that are extended and deliver no reinforcement, were interspersed with fixed-interval trials in a two-component multiple schedule. The interval for each component changed mid-session every session. There were two conditions: an Unsignaled condition where the intervals were changed mid-session without any accompanying stimulus change and a Signaled …

Predicting Deer Hunting Participation Using Theory Of Planned Behavior And Constraint Integrated Theory Of Planned Behavior Models: A Study Of Oregon Big Game Hunters, Suresh Kumar Shrestha
Graduate Theses, Dissertations, and Problem Reports (ETD)
Studies have established that the theory of planned behavior (TPB) is a simple but effective model for providing theoretical explanation as to why people participate in a given recreation activity, including general hunting activity. Understanding leisure constraints is another popular approach in leisure research, which is considered more useful from the practitioners' point of view. Literature suggested that significant relationships exist between constraint dimensions and constructs of theory of planned behavior. It was assumed that integrating constraints to TPB might not only enhance the predicting power of the TPB but might also provide a practical dimension to it. The aims …

Emotion Regulation And Threat Estimation As Mediators Of The Relation Between Cognitive Functioning And Anxiety In Late Life, Caroline M. Ciliberti
Emotion Regulation And Threat Estimation As Mediators Of The Relation Between Cognitive Functioning And Anxiety In Late Life, Caroline M. Ciliberti
Graduate Theses, Dissertations, and Problem Reports (ETD)
Background: Rates of anxiety are generally thought to decline in typically aging older adults. Some theorize that this decline is a result of age-related improvements in emotion regulation. Emotion regulation may require the use of complex cognitive processes, however, which can be impacted by cognitive decline. Indeed, the prevalence of anxiety is high among older adults with cognitive impairment. The current study examined emotion regulation and threat perception as possible mediators in the relation between cognitive functioning and anxiety.;Methods: One hundred adults, aged 60 and older, were recruited from nursing homes, assisted living facilities, and the community. All were asked …

Characterization Of Late Postpartum Sleep Disturbance, Caffeine-Related Performance, And Daily Functioning, Kelsey K. Meekins
Graduate Theses, Dissertations, and Problem Reports (ETD)
The early postpartum period is marked by maternal sleep fragmentation and performance deficits. Although sleep gradually improves in postpartum women, reaction times gradually worsen. This performance deficit is seen beyond 6 weeks postpartum, when many women are expected to return to work, and it is unknown when (or if) new mothers' performance deficits fully recover. The current study used existing data to characterize the late postpartum period (6 months-3 years after the child was born) in terms of recovery from sleep disturbance by monitoring the behavior of mothers on both objective and subjective measures. The current study aimed to describe …
