Mathematical models, requiring substantial data, of hydrologic and water resources systems are under intensive investigation. The processes of data analysis and model building are interrelated so that models may be used to forecast for scientific reasons or decision making. Examples are drawn from research on modeling aquifers, watersheds, streamflow and precipitation in Arizona. Classes of problems include model choice, parameter estimates, initial condition, input identification, forecasting, valuation, control, presence of multiple objectives, and uncertainty. Classes of data analysis include correlation methods, system identification, stationarity, independence or randomness, seasonality, event based approach, fitting of probability distributions, and analysis for runs, range and crossing levels. Time series, event based and regression methods are reviewed. The issues discussed are applied to tree-ring analyses, streamflow gaging stations, and digital modeling of small watersheds and the Tucson aquifers.ISSN

Aeroelastic Analysis of Rotor Blades Using Three Dimensional Flexible Multibody Dynamic Analysis(The University of Arizona., 2008)This study presents an approach based on the floating frame of reference method to model complex three-dimensional bodies in a multibody system. Unlike most of the formulations based on the floating frame of reference method, which assume small or moderate deformations, the present formulation allows large elastic deformations within each frame by using the co-rotational form of the updated Lagrangian description of motion. The implicit integration scheme is based on the Generalized-alpha method, and kinematic joints are invoked in the formulation through the coordinate partitioning method. The resulting numerical scheme permits the usage of relatively large time steps even though the flexible bodies may experience large elastic deformations. A triangular element, based on the first order shear deformable theory, has been developed specifically for folded plate and shell structures. The plate element does not suffer from either shear or aspect-ratio locking under transverse and membrane bending, respectively. A stiffened plate element has been developed that combines a shear deformable plate with a Timoshenko beam. A solid element, that utilized the isoparametric formulation along with incompatible modes, and one-dimensional elements are also included in the element library. The tools developed in the present work are then utilized for detailed rotorcraft applications. As opposed to the conventional approach of using beam elements to represent the rotor blade, the current approach focuses on detailed modeling of the blade using plate and solid elements. A quasi-steady model based on lifting line theory is utilized to compute the aerodynamic loads on the rotor blade in order to demonstrate the capabilities of the proposed tool to model rotorcraft aeroelasticity.

Rapid Capture, Analysis, and Storage of Integrated Circuit Images for Defect Analysis(The University of Arizona., 2010-05)An automated rapid capture, analysis and storage system for identifying chip defects is essential to ensure Intel's "Copy Exactly" methodology with low labor cost and no human subjectivity. In this system, the software will identify where the defects are with a standardized definition of defects. Constraints include the 80% defect detection rate, and Windows XP compatibility. There should be no defects that can be observed by human eye in the product shipments. Three design concepts were generated and two of them are combined to form the final design. The final design consists of a line scan cameras and two LED arrays with different wavelengths. The software design is discussed under detection and compression algorithms. Based on the software testing done, the software can identify on average 96% of the defects and compress the image up to 22 times over the current bitmap format.

Discourse analysis of Retrospective Miscue Analysis sessions: Talking about the reading process with a fourth-grade reader(The University of Arizona., 1999)The purpose of this study was to examine the discourse of six selected Retrospective Miscue Analysis (RMA) session transcripts for effective and promising procedures, questions and discussion strategies. Data sources consisted of session transcripts and interviews to determine how the RMA team's discourse accomplished their intended purposes across six RMA sessions with a fourth grade reader. Phases of the analysis included (1) verifying the existing data sets, (2) selecting six RMA sessions from the set of eleven, (3) conducting and analyzing interviews with the RMA team, (4) structural analysis of sessions, (5) speech act analysis of discourse moves, (6) sequential analysis of question cycles, (7) categorization of patterns that emerged in the data. Three broad discourse themes, based on the RMA team's stated purposes for the RMA sessions, guided the categorization of team members' talk: (1) discourse moves providing revaluing, (2) discourse moves providing instruction, and (3) discourse moves encouraging the reader's strategy use. The structural analysis of the RMA sessions generated elements of the instructional sequences and phases that made up each session, and a profile of RMA session procedures. Findings revealed: the RMA team used a wide range of question types to analyze miscues; discourse patterns involved in instruction and revaluing involved a variety of question cycles, position statement and 'you-statements' about the readers' reading strategies; problematic discourse sequences stemmed from problematic questions, responses and belief structures involved in interactions; by analyzing other readers in comparison with his own reading the reader's self-concept increased.
