Real-Time Registration And Display Of Confocal Microscope Imagery For Multiple-Band Analysis, Scott E. Budge, A.M. Mayampurath, J.C. Solinsky

Electrical and Computer Engineering Faculty Publications

Multiple images acquired in real-time from a confocal microscope in different illumination wavebands are used to construct a three-dimensional understanding of living cell signal propagation. Registration, fusion, and display of these images are performed in real-time using field programmable gate array (FPGA) technology to allow the biological scientist to observe time critical signaling processes as they occur. The registration and display system operates at a rate of up to 15 frames/s, and performs dark offset correction and noise reduction, followed by non-linear correction for lens warp and focal plane tilt, and finally correction for spatial mismatch between the different wavebands. …

Developed Pumping Strategies For Mather Afb Tce Plume, Richard C. Peralta, Bassel Timani

Civil and Environmental Engineering Faculty Publications

Accomplishments prior to BCT Meeting/Phone Conference of 14 October 2004 Prior to 14 October 2004, the best pumping strategy USU achieved manually completely contains both PCE and TCE1 (within revised containment zones proposed by USU on that date), at the end of years 2, 3, 4, 5 and 5-year intervals thereafter. This strategy uses two new extraction wells (USUE3 and USUE4). The strategy did not utilize a recently constructed well EW-12B. USU did not previously know about EW-12B and the well package USU received did not indicate a well at its location, cell (3,58,43). On 14 October, USU also learned …

Los modelos S/O están llegando a ser más comúnmente usados para el desarrollo de normas, planeamiento, diseño del sistema y manejo. Por ejemplo, los encargados del manejo y planificación del agua algunas veces deben decidir como controlar el uso del agua subterránea para originar un futuro favorable y evitar serios problemas. Los modelos S/O pueden ayudar …

Modeling Of The Interactions Between Forest Vegetation, Disturbances, And Sediment Yields, Erkan Istanbulluoglu, David G. Tarboton, Robert T. Pack, Charles H. Luce

Civil and Environmental Engineering Faculty Publications

The controls of forest vegetation, wildfires, and harvest vegetation disturbances on the frequency and magnitude of sediment delivery from a small watershed (∼3.9 km2) in the Idaho batholith are investigated through numerical modeling. The model simulates soil development based on continuous bedrock weathering and the divergence of diffusive sediment transport on hillslopes. Soil removal is due to episodic gully erosion, shallow landsliding, and debris flow generation. In the model, forest vegetation provides root cohesion and surface resistance to channel initiation. Forest fires and harvests reduce the vegetation. Vegetation loss leaves the land susceptible to erosion and landsliding until the vegetation …

Implications Of On-Ground Nitrogen Loading And Soil Transformations On Ground Water Quality Management, M. Almasri, Jagath J. Kaluarachchi

Civil and Environmental Engineering Faculty Publications

This paper presents a modeling approach based on a geographic information system (GIS) to estimate the variability of on-ground nitrogen loading and the corresponding nitrate leaching to ground water. The methodology integrates all point and nonpoint sources of nitrogen, the national land cover database, soil nitrogen transformations, and the uncertainty of key soil and land use-related parameters to predict the nitrate mass leaching to ground water. The analysis considered 21 different land use classes with information derived from nitrogen sources such as fertilizer and dairy manure applications, dairy lagoons, septic systems, and dry and wet depositions. Simulations were performed at …

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 …

Optimization Modeling For Groundwater And Conjunctive Use Water Policy Development, Richard C. Peralta, R. Shulstad

Civil and Environmental Engineering Faculty Publications

Planners must sometimes decide how to restrict or reduce groundwater use to prevent unacceptable future problems. Often there are several alternatives (policies). Comparing policies can involve formulating a sustained groundwater yield optimization problem and computing an optimal groundwater pumping strategy for each. This is easy via the SOMOS simulation/optimization (S/O) model. Subsequent analysis can include: flow simulation to predict transient water level response to pumping; and economic evaluation to estimate costs and returns. Two examples predict the best consequences of potential physical and legal management policies for alluvial and valley basin fill aquifers hydraulically linked to surface waters. Results show …

A Turn To Engineering: The Continuing Struggle Of Technology Education For Legitimization As A School Subject, Theodore Lewis

Publications

In the long march from manual training, the subject which today we call technology education has always had to contend with the question of its legitimacy as valid school knowledge. In this regard, it shares a similar history of struggle with other subjects whose initial entry into the curriculum was based on a utilitarian rather than an academic rationale. Goodson (1983) documents such cases (e.g. geography and biology) showing how in their struggle for acceptance, the primary strategy of advocates was to try to enhance the academic bona fides of their subject. He explained that utilitarian knowledge is associated with …

Technology And Mathematics Standards: An Integrated Approach, Chris Merrill, Mark Comerford

Publications

The article focuses on the use of standards-based teaching and learning that has been gaining significant attention in the education world. State and national associations now base their specific subject area or discipline solely on standards, i.e., International Technology Education Association (ITEA), National Council of Teachers of Mathematics (NCTM), National Science Education Association (NSEA). Moreover, at the public school level, state boards of education are holding school districts accountable for teaching standards-based curricula. It is with the latter definition in mind that the authors created a standards-based, integrated technology and mathematics lesson using the design and construction of stair systems.

Standards-Based Curriculum Development For Pre-Service And In-Service: A “Partnering” Approach Using Modified Backwards Design, Steve Shumway, Jared Berrett

Publications

The article reports that technology teacher educators across the nation are considering what changes will be made to their pre-service teacher education programs to implement the standards in Standards for Technological Literacy (STL) (ITEA, 2000/2002) and to help future teachers learn to develop and teach curriculum that is based on those standards (Custer& amp; Wright, 2002). A recent survey (Reeve, Nielson,& amp; Meade, 2003) revealed that in Utah, a majority of teachers have a copy of the standards and are supportive of them, but they want help implementing standards-based technology education in their classrooms. Initially, a self-evaluation of the teacher …

Critical Issues And Problems In Technology Education, Robert C. Wicklein

Publications

The article informs that to address the need of identifying a comprehensive base for the critical issues and problems, research was conducted to ascertain the perspectives of classroom teachers, university professors, and supervisors of technology education. In addition, the entire population of 132 university department heads/program leaders in technology teacher education, as well as the total population of 55 state and regional supervisors, were selected to receive the survey questionnaire. The critical problem items, insufficient quantities of qualified technology education teachers, inadequate understanding by administrators and counselors concerning technology education, and inadequate understanding by general populace concerning technology education, were …
