- Abstract/Description

Deterministic and stochastic weighting methods are commonly used methods for estimating missing precipitation rain gauge data based on values recorded at neighboring gauges. However, these spatial interpolation methods seldom check for their ability to preserve site and regional statistics. Such statistics and primarily defined by spatial correlations and other site-to-site statistics in a region. Preservation of site and regional statistics represents a means of assessing the validity of...
Show moreDeterministic and stochastic weighting methods are commonly used methods for estimating missing precipitation rain gauge data based on values recorded at neighboring gauges. However, these spatial interpolation methods seldom check for their ability to preserve site and regional statistics. Such statistics and primarily defined by spatial correlations and other site-to-site statistics in a region. Preservation of site and regional statistics represents a means of assessing the validity of missing precipitation estimates at a site. This study evaluates the efficacy of traditional interpolation methods for estimation of missing data in preserving site and regional statistics. New optimal spatial interpolation methods intended to preserve these statistics are also proposed and evaluated in this study. Rain gauge sites in the state of Kentucky are used as a case study, and several error and performance measures are used to evaluate the trade-offs in accuracy of estimation and preservation of site and regional statistics.

GIS is expected to differ from other digital spatial data handling packages by virtue of its emphasis on spatial analysis and modeling, yet major limitations of spatial analytical capabilities are still observed. To identify the types of spatial analysis which are desirable and appropriate to GIS, this thesis proposes a systematic 'building-blocks' approach for the identification of data models and spatial analytical tools to develop a flexible and powerful GIS spatial analysis and modeling...
Show moreGIS is expected to differ from other digital spatial data handling packages by virtue of its emphasis on spatial analysis and modeling, yet major limitations of spatial analytical capabilities are still observed. To identify the types of spatial analysis which are desirable and appropriate to GIS, this thesis proposes a systematic 'building-blocks' approach for the identification of data models and spatial analytical tools to develop a flexible and powerful GIS spatial analysis and modeling environment. The building-blocks approach will be demonstrated in this thesis by examining a ground water flow model in MODFLOW, an SDA package designed specifically for this purpose. Procedures in MODFLOW will be disassembled into their primitive component functions, or building-blocks, which will then be sought out in ARC/INFO, representing a modern, general-purpose GIS. In the process, the levels of integration between GIS and SDA will be encountered and discussed.

- Abstract/Description

System modeling has the potential to enhance system design productivity by providing a platform for system performance evaluations. This model must be designed at an abstract level, hiding system details. However, it must represent any subsystem or its components at any level of specification details. In order to model such a system, we will need to combine various models-of-computation (MOC). MOC provide a framework to model various algorithms and activities, while accounting for and...
Show moreSystem modeling has the potential to enhance system design productivity by providing a platform for system performance evaluations. This model must be designed at an abstract level, hiding system details. However, it must represent any subsystem or its components at any level of specification details. In order to model such a system, we will need to combine various models-of-computation (MOC). MOC provide a framework to model various algorithms and activities, while accounting for and exploiting concurrency and synchronization aspects. Along with supporting various MOC, a modeling environment should also support a well developed library. In this thesis, we have explored various modeling environments. MLDesigner (MLD) is one such modeling environment that supports a well developed library and integrates various MOC. We present an overview and discuss the process of system modeling with MLD. We further present an abstract model of a Network-on-Chip in MLD and show latency results for various customizable parameters for this model.

- Abstract/Description

Geographic information systems (GIS) have been increasingly used in urban transportation planning and modeling. One key advantage of GIS is its ability to integrate and analyze various kinds of geographically referenced data. Modeling and analysis tools used to predict travel patterns should be shaped by changes in spatial organization that are currently taking place. Utilizing the detailed data made available by GIS, this study investigates the potential improvements offered to the...
Show moreGeographic information systems (GIS) have been increasingly used in urban transportation planning and modeling. One key advantage of GIS is its ability to integrate and analyze various kinds of geographically referenced data. Modeling and analysis tools used to predict travel patterns should be shaped by changes in spatial organization that are currently taking place. Utilizing the detailed data made available by GIS, this study investigates the potential improvements offered to the conventional trip generation and trip distribution models by explicitly referencing the spatial land use and street network patterns within traffic analysis zones (TAZs).
