Mesospheric Temperature Climatology Above Utah State University, Joshua P. Herron

Physics

A Rayleigh-scatter lidar has been in operation at Utah State University (41.7o N, 111.8 ° W) starting in September 1993 until the present (October 2003). The return profiles from the atmosphere have been analyzed to provide temperature measurements of the middle atmosphere from 45 to 90 km. Various methods of averaging were used to construct a temperature climatology of the region based on these observations. The data analysis algorithm has been critically analyzed to find possible sources of error, and has been compared to an independently derived technique. The resulting temperatures have been compared to other mid-latitude lidars with good …

Software For Optimizing International Water Resources Management, Richard C. Peralta, S. Wu

Civil and Environmental Engineering Faculty Publications

The Simulation/Optimization MOdeling System (SOMOS) has modules adapted for a range of international water resource management needs. The SOMOA module is best for field groundwater and conjunctive water management situations. It employs several analytical simulation models and several optimization methods to give appropriate optimal guidance for situations having sparse data. SOMOA requires understanding of the limitations of common analytical equations. It does not require experience in finite difference or element numerical modeling. SOMOS also has modules ideal for situations in which there is sufficient data for numerical modeling or aquifer and stream-aquifer systems. Emphasized here are SOMOA and its applications …

Husserl's Phenomenological Reduction Revisited: An Attempt Of A Renewed Account, Sebastian Luft

Philosophy Faculty Research and Publications

This essay attempts a renewed, critical exposition of Husserl’s theory of the phenomenological reduction, incorporating manuscript material that has been published since the defining essays of the first generation of Husserl research. The discussion focuses on points that remain especially crucial, i. e. the concept of the natural attitude, the ways into the reduction, and the question of the “meaning of the reduction”. The reading attempted here leads to two, not necessarily related, focal points: a Cartesian and a Life-world tendency. In following these two paths, Husserl was consistent in pursuing two evident leads in his philosophical enterprise; however, he …

Husserl’S Theory Of The Phenomenological Reduction: Between Life-World And Cartesianism, Sebastian Luft

Philosophy Faculty Research and Publications

This essay attempts a renewed, critical exposition of Husserl's theory of the phenomenological reduction, incorporating manuscript material that has been published since the defining essays of the first generation of Husserl research. The discussion focuses on points that remain especially crucial, i.e., the concept of the natural attitude, the ways into the reduction (and their systematics), and finally the question of the "meaning of the reduction." Indeed, in the reading attempted here, this final question leads to two, not necessarily related, focal points: a Cartesian and a Life-world tendency. It is my claim that in following these two paths, Husserl …

Development Of An Instrumented Deep−Tillage Implement For Sensing Of Soil Mechanical Resistance, Viacheslav I. Adamchuk, Andrey V. Skotnikov, Justin D. Speichinger, Michael F. Kocher

Department of Agricultural and Biological Systems Engineering: Faculty Publications

Variable−depth tillage has the potential for economic and environmental benefits to modern crop production. Varying tillage depth according to local soil conditions prevents the waste of energy and preserves soil ecology. A prototype instrumentation system was developed based on a conventional implement for deep tillage. It was equipped with two load cells and two sets of strain gauges for sensing the load applied to the implement during tillage. Two linear pressure distribution models (full and redundant) were used to describe the change of soil mechanical resistance with depth. These models were then used to compare estimates of soil mechanical resistance …

Cooperative Learning In The Middle School : Is It A Developmentally Appropriate Strategy?, Laura C. Guilford

Graduate Research Papers

"Cooperative learning is the instructional use of small groups so that students work together to maximize their own and each other's learning" (Holt, 1993, p. 5). The strategy sounds simple, and it has existed throughout history in some format, but there are many aspects.that come into play when cooperative learning is used. This review of literature examines what cooperative learning is, what the benefits of using cooperative learning strategies are, what problems can occur, and whether cooperative learning is an appropriate strategy for middle level students.· The author discusses recommendations for resolving some of the problems that teachers have with …

Energy Aware Design And Analysis For Synchronous And Asynchronous Circuits, Jia Di

Retrospective Theses and Dissertations

Power dissipation has become a major concern for IC designers. Various low power design techniques have been developed for synchronous circuits. Asynchronous circuits, however. have gained more interests recently due to their benefits in lower noise, easy timing control, etc. But few publications on energy reduction techniques for asynchronous logic are available.

Power awareness indicates the ability of the system power to scale with changing conditions and quality requirements. Scalability is an important figure-of-merit since it allows the end user to implement operational policy. just like the user of mobile multimedia equipment needs to select between better quality and longer …

The focus of this dissertation is on creating Adaptive Intelligent User Interfaces to facilitate enhanced natural communication during the Human-Computer Interaction by recognizing users' affective states (i.e., emotions experienced by the users) and responding to those emotions by adapting to the current situation via an affective user model created for each user. Controlled experiments were designed and conducted in a laboratory environment and in a Virtual Reality environment to collect physiological data signals from participants experiencing specific emotions. Algorithms (k-Nearest Neighbor [KNN], Discriminant Function Analysis [DFA], Marquardt-Backpropagation [MBP], and Resilient Backpropagation [RBP]) were implemented to analyze the collected data signals …

Modified Sierpinski Fractal Antenna, Tripti Luintel

Electronic Theses and Dissertations

Fractal antennas have the potential to provide multi-band solution through the property of self similarity that the fractal shape possess. This thesis deals with some modifications of the original Sierpinski fractal patch antenna, providing additional parameters to optimize in order to get the required radiation characteristics. A systematic study of the original Sierpinski monopole was done to gain an insight on the operation and multi-band behavior of the antenna and a similar study was done to find out why the patch version of Sierpinski lacks multi-band behavior. A Sierpinski antenna is designed by merging a grid and the fractal restoring …

In this study the structure and the magnetic properties of polymer microspheres, filled with magnetite nanoparticles are investigated. Average particle size of magnetite nanoparticles before and after being introduced into polymer microspheres, and the distance between nanoparticles in the polymer microspheres, are measured. Magnetization curve of polymer magnetic microspheres (PMMS) is determined. The magnetic susceptibility of PMMS with various diameters, and the dependence of PMMS magnetic susceptibility on diameter are determined. Magnetization occurs due to the orientation of PMMS as a magnetic moment. The total magnetic moment of PMMS is the sum of magnetic moments of PMMS sections which consist …

Analysis Of Fading Characteristics Of A Free Space Optical Channel, Roger Douglas Halbing

Retrospective Theses and Dissertations

In this thesis we shall consider how well the gamma-gamma theory models the fading of experimental data obtained from two line of sight experiments of 1km and 13km. Frequency Analysis of the intensity fluctuations collected from the different aperture sizes will be compared to the two-scale theory of the gamma-gamma model. Statistical analysis of the channel intensity for different aperture sizes will be performed and the results will be compared to the gamma-gamma theory to determine if the gamma-gamma model is valid over greater distances than has previously been investigated .

Evaluation Of Ten Psychometric Criteria For Circumplex Structure, G. Scott Acton, William Revelle

Articles

This study tested for sensitivity to circumplex structure in six existing and four new psychometric criteria that assess the circumplex properties of interstitiality, equal spacing, constant radius, and no preferred rotation. Simulations showed one criterion to be sensitive to equal versus unequal axes(Fisher Test) and four to be sensitive to interstitiality versus simple structure (Gap Test, Variance Test 2, Rotation Test, and Minkowski Test). Five criteria were ineffective (Squared Loadings Index, Gap* Test, Gap Difference Test, Cosine Difference Test, and Variance Test 1). Deviation scoring improved the effectiveness of most criteria and is thus recommended for assessing circumplex structure. This …

A Dynamic And Stochastic Analysis Of Fertilizer Use In Swidden Agriculture, Gregory Deangelo, Amitrajeet A. Batabyal

Articles

The number of times a crop can be harvested on a cleared parcel of forest land (CPFL) before this land must be fallowed is dependent on the decision to use or not to use fertilizers to enhance soil fertility. As such, we first construct a theoretical model of fertilizer use by a swidden cultivator when this cultivator can choose whether or not to enhance soil fertility by using fertilizers. Second, we analyze two different policies (fertilizer use and no fertilizer use) for overseeing the problem of soil fertility deterioration on the CPFL. Finally, we identify a particular likelihood function and …
