Scope and Method of Study: Most developing countries, including Iraq, have very poor wind data. Existing wind speed measurements of poor quality may therefore be a poor guide to where to look for the best wind resources. The main focus of this study is to examine how effectively…

The effect of particle size, velocity, and angle of attack was investigated on the roughness and erosion rate of unmasked channels machined in borosilicate glass using abrasive jet micro-machining (AJM). Single impact experiments were conducted to quantify the damage due to the …
The manuscript presented herein is based on the investigation of the short and long term properties of fly ash based geopolymer concrete (GPC) and their link to fly ash characteristics. Fly ash (FA) exhibits a significantly different particle morphology, which impacts the mechan…
The use of a system of detention reservoirs distributed across a region has been gaining interest as an innovative way to manage riverine flooding. An open problem is the role played by the spatial configuration of detention projects in regulating the flow. Possible locations fo…
As the polymer industry becomes more competitive, polymer manufacturers face increasing pressures for production cost reductions and more stringent "polymer quality" requirements. To achieve these goals one needs to develop comprehensive mathematical models capable of predicting…
The ability to detect biomolecules and chemicals accurately, effectively, and promptly in variety of environments including applications in homeland security, clinical diagnoses, environmental monitoring, food safety, etc. has always been an important issue. For each of these ap…
Many research studies have characterized the primary productivity of tropical forests and contributed to highlighting the complexity of underlying drivers of the ecological system. However, few studies have explored how productivity changes across multiple scales and how the dri…
Currently, there is limited ability to follow Listeria monocytogenes through food-service environments, and there remain knowledge gaps concerning the underlying mechanisms that govern surface-to-surface transfer processes. Therefore, the objectives were to: (1) develop a method…
In the construction industry, water transmission pipelines projects typically require twodimensional drawings for transferring design data to the field. These drawings are referred as construction documents and serve as the source documents for subsequent facility management. Ho…
Bu çalışmada lise öğrencilerinin matematiksel modelleme becerilerinin incelenmesi amaçlanmaktadır. Araştırmada aşağıdaki sorulara cevap aranmıştır: • Lise öğrencilerinin mantık konusundaki matematik başarısı hangi düzeydedir? • Lise öğrencilerinin matematiksel modelleme becerile…
Ecological models allow resource managers to evaluate human impacts on fish and their habitat. However, quantitative methods that incorporate and assess uncertainty in these models are rare. These models require fish life history information, which is often uncertain, and can th…
University landscape architecture program studios can harbor unethical studio environments. Current accreditation standards and antiquated views on the value of models in representation can lead to a focus on the technical requirements of curriculum, rather than the effect of st…
This dissertation is composed of projects on three aspects of gathering and learning from data in the social sciences: drawing representative samples, taking valid measurement, and making warranted inductive inferences.
As I make my way through the world, I rely on my senses to inform me of the things and events around me that allow me to continue living and growing as a human being. I am keenly aware of myself as a living human consciousness that appears to inhabit a body. My mind is the cente…
Despite decreases in acidic deposition since the 1970s, the recovery of surface waters from acidification has been limited primarily due to the depletion of exchangeable base cations, net mineralization of organic sulfur and nitrogen and release of previously retained SO 4 2- an…
Uncertainty in climate predictions arises from three distinct sources: the internal variability of the climate system, which refers to natural fluctuations in climate that occur even in the absence of external forcing, model or structural uncertainty, as different models make di…
Nearly every movement we make reflects a decision. This decision likely involves a trade-off between maximizing reward and minimizing effort. How fast we move, vigor, can reveal how we value reward and effort when making movement decisions. The goal of this dissertation is to ga…
In the United States, the Magnuson-Stevens Reauthorization Act mandates that all federally fished species must have catch limits, which can be challenging for data-limited species. One approach is to assess and manage a group of species with similar life history characteristics,…
Knight of Drones is a hybrid twin-stick top-down shooter and side-scrolling platformer that aims to bring vintage gameplay to a contemporary game engine. A single swatch of the top-down game mode and a pair of levels from the side-scrolling game mode will be presented beginning …
