Extending the Abstract Data Model.
<p>The Abstract Data Model (ADM) was developed by Sanderson [19] to model and predict semantic loss in data translation between computer languages. In this work, the ADM was applied to eight languages that were not considered as part of the original work. Some of the languages were found to support …

Arc Hydro data model for Ethiopian watersheds
… (MoWR) planned to develop a digital hydrologic data model that supports management of the country’s water resources. The purpose of this project is to use the Arc Hydro data model organize and manage water resource data in Ethiopia. To accomplish this, raw Shuttle Radar Topographic Mission …

A Spatio-Temporal Data Model for Zoning
… in querying spatio-temporal planning data. Using a data model designed specifically to facilitate the querying of historical zoning information, queries can be performed to answer basic zoning questions such as "what is the zoning history for a specific parcel of land?" This work …

3D Simulator for Wind Interferometer Data-Model Comparison
… and GPS signals. Thus, predicted & modeling this region is important, yet models (both empirical and first principles) do a poor job of characterizing the variability of this region. One of the main objectives of the NASA ICON mission is to measure the variability of the ionosphere …

A Dynamic Space-Time Panel Data Model of State-Level Beer Consumption
A dynamic space-time panel data model containing random effects is used to examine state-level beer consumption over the period of 1970 to 2007 for the 48 contiguous US states and the District of Columbia. A valuable aspect of dynamic space-time panel data models is that the parameter estimates …

Extensions to the iCalendar Data Model Hierarchical Schedules and Temporally Related Events
… and relationships, however, they cannot be modeled in mainstream computer calendaring tools. As a result, when applying these types of schedules to a computer calendar, a great deal of human calculation, manual manipulation, and data entry are required to get the schedule information into …

MSMEs (Microsoft, Small and Medium Enterprises) and Democracy, a Panel Data Model
<p>This paper focuses on different national economic development structures, such as microsmall-medium-enterprises (MSMEs) vs. big or state-owned enterprises and their relations with political development. A well-established literature argues that MSMEs are conducive to economic growth. Existing …

Suitability of the NIST Shop Data Model as a Neutral File Format for Simulation
… (NIST) has developed an XML-based information model (XSD) called the Shop Data Model (SDM), which is used to describe the contents of a neutral file format (NFF) that is being promoted as a means to make manufacturing simulation technology more accessible to a larger group of potential …

Ion Temperatures in Earth's Inner Magnetosphere: Ring Current Dynamics, Transient Effects, and Data-Model Comparisons
… implemented into the Comprehensive Ring Current Model (CRCM); the temperatures are based on 2-D equatorial maps derived from remotely imaged energetic neutral atom (ENA) measurements. The high-speed-stream-driven event on 22 July 2009 and the coronal mass ejection-driven event on 30-31 October …

Bayesian Methodology for Missing Data, Model Selection and Hierarchical Spatial Models with Application to Ecological Data
Ecological data is often fraught with many problems such as Missing Data and Spatial Correlation. In this dissertation we use a data set collected by the Ohio EPA as motivation for studying techniques to address these problems. The data set is concerned with the benthic health of Ohio's waterways. …

Comparative Genome Analysis of Three Brucella spp. and a Data Model for Automated Multiple Genome Comparison
… research represents the development stage of a database-backed pipeline for comparative analysis of multiple genomes. The genomes of three recently sequenced species of Brucella were compared and a superset of known and hypothetical coding sequences was identified to be used in design of a …
