Structuring Emperical Methods For Reuse And Efficiency In Product Development Processes, Marshall Edwin Bare
Structuring Emperical Methods For Reuse And Efficiency In Product Development Processes, Marshall Edwin Bare
Theses and Dissertations
Product development requires that engineers have the ability to predict product performance. When product performance involves complex physics and natural phenomena, mathematical models are often insufficient to provide accurate predictions. Engineering companies compensate for this deficiency by testing prototypes to obtain empirical data that can be used in place of predictive models. The purpose of this work is to provide techniques and methods for efficient use of empirical methods in product development processes. Empirical methods involve the design and creation of prototype hardware and the testing of that hardware in controlled environments. Empirical methods represent a complete product development sub-cycle …

Transcription factor binding sites (TFBS) impart specificity to cellular transcriptional responses and have largely been defined by consensus motifs derived from a handful of validated sites. The low specificity of the computational predictions of TFBSs has been attributed to ubiquity of the motifs and the relaxed sequence requirements for binding. We posited that the inadequacy is due to limited input of empirically verified sites, and demonstrated a multiplatform approach to constructing a robust model. Results: Using the TFBS for the estrogen receptor (ER)alpha (estrogen response element [ERE]) as a model system, we extracted EREs from multiple molecular and genomic platforms …

A tailsitter UAV has unique advantages over typical fixed wing aircraft or hovercraft. This paper highlights topics of interest in our preliminary research in developing a tailsitter UAV. An aerodynamic model and quaternion-based attitude and position control scheme is presented for controlling a tailsitter through hover maneuvers, with simulation results. Desired trajectories are also developed through feedback linearization of the dynamic equations, intended for quaternion-based attitude control. Finally, a hardware platform is proposed.
Spatial And Temporal Model Validation: Representing Landscape Properties And Processes Across Scales, C. S. Renschler
Spatial And Temporal Model Validation: Representing Landscape Properties And Processes Across Scales, C. S. Renschler
International Congress on Environmental Modelling and Software
Continuous modeling of landscape processes and their validation requires representingenvironmental properties for model input and output across scales. A combination of a scaling theory, aGeospatial Project Management Tool (GeoProMT), and a GIS-based environmental modeling interface,allows interdisciplinary collaborators to efficiently handle and communicate the scaling (or transformation)of geospatial information of properties and processes across scales. This integrated approach of theory,project management tool, and modeling interface can be applied to any environmental model and softwaredevelopment. The integrated modeling is based on the Geospatial Interface for the Water Erosion PredictionProject (GeoWEPP) that enables soil and water conservationists to assess soil erosion taking into …

Water Resources Management And Water Availability In The Elbe River Basin Under Conditions Of Global Change, S. Kaden, M. Kaltofen, H. Koch
International Congress on Environmental Modelling and Software
Global change challenges long-term planning in water management. Practical management requires plausible and consistent scenarios as well as assessments of possible climatic, technological and social developments and their impacts. These problems are subjects of research within the GLOWA Elbe II – project. The project’s goal is to develop a water management strategy for possible adaptation to global change in the Elbe river basin (about 150,000 km2). One important component of the multi-disciplinary project is the analysis of conflicts related to water availability. For that purpose a detailed water management model for the whole Elbe river basin, including the Czech part …
Multi-Crop Plant Growth Modeling From Field To Watershed For Water Quality And Management, G. S. Mcmaster, James C. Ascough Ii, D. A. Edmunds, L. E. Wagner, F. A. Fox
Multi-Crop Plant Growth Modeling From Field To Watershed For Water Quality And Management, G. S. Mcmaster, James C. Ascough Ii, D. A. Edmunds, L. E. Wagner, F. A. Fox
International Congress on Environmental Modelling and Software
Agricultural models and decision support systems (DSS) for assessing water quality and management are increasingly being applied to diverse geographic regions at different scales. This requires models that can simulate many different common and alternative crops. However, very few plant growth models are available that “easily” can simulate the growth of many crops, and these models lack the scientific detail incorporated into crop-specific models. One option available is a suite of plant growth models based on the original plant growth model used in the Environmental Policy Integrated Climate (EPIC) model. Various versions of the original EPIC plant growth model have …

An Integrated Environmental Decisional Support System Framework Using Earth Observation, Cellular Automata And Multi-Agent System, S. De Luca, D. Maggio, M. Balsi
An Integrated Environmental Decisional Support System Framework Using Earth Observation, Cellular Automata And Multi-Agent System, S. De Luca, D. Maggio, M. Balsi
International Congress on Environmental Modelling and Software
The paper is about the modeling of natural disasters, taking in account both the natural elements than the human behaviors and working on mixed scenarios of forests, build-up area, rivers and roads. We propose a three steps methodology that spans from the earth observation to categorization towards environment forecast modeling and action planning. As case study, we focused on fire spreading. Geographical Information Systems (GIS) and remote sensing tools are used to implement this scenario, while a multi-layer cellular automata is used to model the environment evolution. Finally, a multi-agent system is used to model human behaviors. We evaluated the …

Development Of An Integrated Decision Support System For Water Quality Control In The Upper Litani Basin, Lebanon, Hamed Assaf, Mark Saadeh
International Congress on Environmental Modelling and Software
Compared to the limited water supply in the Middle East, Lebanon is perceived to be a water rich country. Yet, it faces a growing water supply problem due to many factors including increases in demand, inadequate investment in infrastructure, and deterioration of water quality. Being the foremost water resource in Lebanon, the Litani River is at the center of several major water supply and irrigation schemes. However, the river water quality is severely impacted by the current practice of releasing untreated sewage into its water body, specifically in its upper basin which is home to about half a million inhabitants. …
Uncertainty Analysis Associated With Rainfall Spatial Distribution In An Experimental Semiarid Watershed, Northeastern Brazil, Lúcio Flávio Ferreira Moreira, A. M. Righetto, V. M. De A. Medeiros
Uncertainty Analysis Associated With Rainfall Spatial Distribution In An Experimental Semiarid Watershed, Northeastern Brazil, Lúcio Flávio Ferreira Moreira, A. M. Righetto, V. M. De A. Medeiros
International Congress on Environmental Modelling and Software
In this paper the main goal was to analyze the effect of spatial variability of rainfall on runoff in an experimental monitored watershed (2.108 km2) located on a semiarid region (Seridó Potiguar), Rio Grande do Norte-Brazil. To accomplish this, a rainfall-runoff-sediment hydrologic model was used. The study area was divided into 143 elements (planes and channels). Rainfall spatial distribution, estimated using the inverse of distance method, was used as input to calculate rainfall spatial variability index for three observed storm events and different combinations of recording gauge arrangements. This index was considered in this study as an indicator used to …

Logisnet: A Tool For Multimethod, Multilayer Slope Stability Analysis, G. Legorreta Paulin, M. I. Bursik
International Congress on Environmental Modelling and Software
Shallow landslides or slope failures have been studied from several points of view. In particular, numerous methods have been developed to assess slope stability. However, little work has been done on the systematic comparison of different techniques, and the incorporation of vertical contrasts of geotechnical properties in multiple soil layers. In this research, stability is modeled by using LOGISNET, an acronym for logistic regression, Geographic Information System and Neural Network. LOGISNET is a project of which the main purpose is to provide government planners and decision makers a tool to assess landslide susceptibility. The system is fully operational for models …

The Use Of Inductive And Deductive Reasoning To Model Snowmelt Runoff From Northern Mountain Catchments, P. F. Dornes, J. W. Pomeroy, A. Pietroniro, S. K. Careyc, W. L. Quinton
The Use Of Inductive And Deductive Reasoning To Model Snowmelt Runoff From Northern Mountain Catchments, P. F. Dornes, J. W. Pomeroy, A. Pietroniro, S. K. Careyc, W. L. Quinton
International Congress on Environmental Modelling and Software
Reliable hydrological modeling at small to medium scales is very difficult. At these scale, models require incorporation of both detailed process understanding and inputs along with information gained from observations of basin-wide streamflow phenomenon; essentially a combination of deductive and inductive approaches. At Granger Creek, part of the Wolf Creek Research Basin in the mountains of the Yukon Territory, Canada, sparse and shrub tundra cover the basin and soils are frozen at the time of snowmelt. Wind redistributes snow to north facing slopes and shrub tundra areas, while spring melt rates are much higher on south facing slopes due to …

Black Liquor Droplet Combustion And Modeling, Warren Benjamin Roberts
Black Liquor Droplet Combustion And Modeling, Warren Benjamin Roberts
Theses and Dissertations
Black liquor is an intermediate product of pulp production. Recovery boilers process black liquor to recover the inorganic material for recycling in the mill and to generate electricity and steam for the paper mill. Black liquor droplet combustion rates and mechanisms dictate many aspects of recovery boiler performance. This investigation documents new experimental data on single droplet pyrolysis and combustion in a laboratory furnace that mimics many of the essential features of commercial boilers (temperature, composition, droplet size, etc.). These experiments monitored single droplets placed on a thermocouple wire and suspended from a mass balance. Simultaneous video images and pyrometry …

Techniques In The Design Of Thermomechanical Microactuators, Larry L. Howell, Timothy W. Mclain, Michael S. Baker, Christian D. Lott
Faculty Publications
The purpose of this chapter is to provide fundamental background for the design of thermomechanical microactuators. Actuation has been a particularly challenging aspect of microsystem development. Many actuation approaches used at the macro level, such as hydraulics, pneumatics, electric motors, internal combustion engines and turbines, are either too difficult to fabricate at the micro level or do not work well at that scale. Electrostatic attraction is one approach that has been widely used for actuation of microsystems; however, electrostatic actuators tend to have high voltage requirements and low output force capabilities. While electrostatic actuation is suitable for many applications, some …
