Towards Artificial Proprioception In The Mandibular Full Arch Fixed Implant Prosthesis, Md Abu Hasan Dec 2016

Towards Artificial Proprioception In The Mandibular Full Arch Fixed Implant Prosthesis, Md Abu Hasan

Mechanical and Aerospace Engineering Dissertations - Archive

Full arch fixed implant prosthesis has been one of the most effective treatment modalities for fully edentulous patients over the last few decades. However, due to lack of proprioception occlusal overload is experienced by the prosthesis and its components causing major biomechanical complications such as screw/abutment fracture, framework fracture, and bone loss. The currently available approaches for the overload management rely on external appliances such as an occlusal splint or bite guard and result in occlusal discomfort and high patient dissatisfaction. In this research, an approach to induce artificial proprioception in the full arch fixed implant prosthesis is proposed. However, …

System Health Monitoring Using Multiple-Model Adaptive Estimation Techniques, Stanley Ryan Sifford Dec 2016

System Health Monitoring Using Multiple-Model Adaptive Estimation Techniques, Stanley Ryan Sifford

Mechanical and Aerospace Engineering Dissertations - Archive

Monitoring system health for fault detection and diagnosis by tracking system parameters concurrently with state estimates is approached using a new multiple-model adaptive estimation (MMAE) method. This novel method is called GRid-based Adaptive Parameter Estimation (GRAPE). GRAPE expands existing MMAE methods by using new techniques to sample the parameter space. GRAPE expands on MMAE with the hypothesis that sample models can be applied and resampled without relying on a predefined set of models. GRAPE is initially implemented in a linear framework using Kalman filter models. A more generalized GRAPE formulation is presented using extended Kalman filter (EKF) models to represent …

Non-Invasive Measurement Of The Internal Temperature Of Heat-Generating Bodies, Dean Raymond Anthony Dec 2016

Non-Invasive Measurement Of The Internal Temperature Of Heat-Generating Bodies, Dean Raymond Anthony

Mechanical and Aerospace Engineering Theses - Archive

While the surface temperature of a heat-generating solid body can be measured using a variety of methods, there is a scarcity of techniques that exist for non-invasively measuring the temperature inside the solid body. Internal temperature measurement is very desirable as mere measurement of surface temperature gives no indication of the internal temperature. The highest temperature, usually located at the core of the body, dictates system performance and safety. For example, Li-ion cells provide good energy storage and conversion characteristics, but unfortunately suffer from safety problems related to overheating due to insufficient heat removal during operation. The following thesis presents …

Residual Effects Of Nitrogen Fertilization On Soil Nitrogen Pools And Corn Growth, Meghan E. Moser Dec 2016

Residual Effects Of Nitrogen Fertilization On Soil Nitrogen Pools And Corn Growth, Meghan E. Moser

Open Access Theses

Given the dynamic nature of soil nitrogen (N), inorganic N fertilization to corn (Zea mays L.) has potential to alter N pool balance by creating an accumulation or depletion of soil N. Current corn N recommendations in the common corn-soybean rotation of Indiana strive to find the best N rate that maximizes producer profit. Increasing our understanding of soil N will inform producers if they should adjust fertilizer rates for corn to influence maintenance of organic N and Carbon. Our objective was to determine residual N effects from fertilized corn in a corn-soybean rotation by measuring (1) soil N …

Origins And Maintenance Of Diversity In A Vertebrate Parthenogen, Alex Scott Hall Dec 2016

Origins And Maintenance Of Diversity In A Vertebrate Parthenogen, Alex Scott Hall

Biology Dissertations - Archive

Clonal lineages are expected to experience a decline in fitness over time due to their inability to decouple deleterious and beneficial alleles. Individually, however, asexual populations pass twice as much of their DNA per generation as sexual lineages. This balancing act between Muller's Ratchet and the lack of the two-fold cost of sex in asexuals brings significant scientific intrigue to instances of asexual populations. Among vertebrates, squamates (and mainly lizards) are uniquely capable of true parthenogenesis whereby females reproduce without males. These lineages are always hybrid, as is the case with parthenogenetic Aspidoscelis lizards (Teiidae). In particular, the checkered whiptail …
