Investigating Correlation Between Availability Of Free Time Facilities For Pupils And Their Educational Achievements While Exploiting Linked Data And Volunteered Geographic Information, Peter Kovar

Dissertations

The advent of Semantic Web as an extension of the current World Wide Web (Web) brings methods and technologies to structure the data, interlink it with other related data and capture its semantics. This holds for new data to be published as well as for the data already on the Web. The interlinking of data led to definition of a linked data paradigm and the Semantic Web allows for creating a Global Linked Data Space. The linked data sets can combine data coming from heterogeneous sources. Using ontologies the meaning in data from different areas of interest can be compared …

Solids Accumulation Rates Of Latrines At Rural Schools In Nimba County, Liberia, Caraline M. Murphy

USF Tampa Graduate Theses and Dissertations

Access to appropriate sanitation facilities as well as access to clean drinking water are considered fundamental human rights (Carr, 2001; Bjorklund & Sjodin, 2010), yet roughly 2.5 billion people on the planet lack access to an improved form of sanitation (WHO/UNICEF, 2014). Additionally, many entities responsible for emergency excreta management and sanitation management design guidelines, specifically solids accumulation rates in latrine pits, use rates that are 30-60 years old and may be established from dated knowledge on diet and lifestyle trends (Franceys et al., 1992; Harvey et al., 2002; Harvey, 2007). Using solids accumulation rates that are dated as well …

Integration Of An Energy Balance Snowmelt Model Into An Open Source Modeling Framework, A. Sen Gupta, David G. Tarboton, P. Hummel, M. E. Brown, S. Habib

Civil and Environmental Engineering Faculty Publications

This paper presents a data model for organizing the inputs and outputs of an energy balance snowmelt model (the Utah Energy Balance Model, UEB) that provides a foundation for its integration into the EPA BASINS modeling framework and enables its coupling with other hydrologic models in this system. Having UEB as a BASINS component has facilitated its coupling with the Geospatial Streamflow Forecast Model (GeoSFM) to compute the melting of glaciers and subsequent streamflow in the Himalayas. The data model uses a combination of structured text and network Common Data Form (netCDF) files to represent parameters, geographical, time series, and …


Event-Based Hydrologic Model Calibration Using Nexrad In A Data-Poor Region Of Southern New Jersey, Christopher Siegel Mar 2015

Event-Based Hydrologic Model Calibration Using Nexrad In A Data-Poor Region Of Southern New Jersey, Christopher Siegel

Theses and Dissertations

Proper calibration of hydrologic models requires both reliable observed stream flow and precipitation data. Southern New Jersey has a notable lack of observed precipitation data, in particular, at the event scale; therefore model calibration represents a significant challenge. From a design standpoint this has not been a major concern as hydrologic models have been driven using design storms and are not calibrated. However, the need for research and impact analyses in the face of climate change (changes in extreme precipitation and sea-level rise in particular) and expected population growth in the region requires calibrated models, and reliable observed precipitation data …

Assessment Of Multi-Story Building Seismic Design Factors With Structural Irregularity, El Sayed Abdel Naby Abdel Aziz Abou Khalifa Mar 2015

Assessment Of Multi-Story Building Seismic Design Factors With Structural Irregularity, El Sayed Abdel Naby Abdel Aziz Abou Khalifa

Theses

Many high-rise buildings are practically irregular as a result of the architectural and service requirements in the design process, errors and modifications during the construction phase, and changes of the building use throughout its service life. Structural irregularities could increase the uncertainties related to the ability of the building to meet the design objectives. This study is thus devoted to assess the safety margins and calibrate the seismic design response factors of modern high-rise buildings with different vertical irregularity features. A brief survey of the most common vertical irregularities in reinforced concrete multi-story buildings is conducted to select reference structures. …

Risk Management In Motorway Ppp Projects: Empirical-Based Guidelines, Nunzia Carbonara, Nicola Costantino, Louis Gunnigan, Roberta Pellegrino

Articles

This paper deals with the topic of risk management in Public–Private Partnership (PPP). The analysis of the related literature reveals that risks must be analyzed and managed on a context-specific approach, and that there is a lack of a comprehensive study on the appropriate risk mitigation strategies for each risk embedded in PPP projects. Focusing on the transport sector, based on the results of a Delphi survey, the paper provides guidelines for both public and private parties in defining a list of significant risks in PPP motorway projects, and identifying for them both the effective allocation and the suitable mitigation …


A Novel Approach To Solve The Great Circle Track Based On Rotation Transformation, Chih-Li Chen, Tsung-Hsuan Hsieh, Tien-Pen Hsu Feb 2015

A Novel Approach To Solve The Great Circle Track Based On Rotation Transformation, Chih-Li Chen, Tsung-Hsuan Hsieh, Tien-Pen Hsu

Journal of Marine Science and Technology–Taiwan

The great circle track (GCT) is composed of several rhumb lines in practice. Given the initial conditions, the waypoints along the GCT can be determined by the navigator. To reduce the complex calculation in a space system, transforming the system into a planar coordinate one is considered. Thus, an idea of the plane of the celestial meridian in celestial navigation is proposed to determine the waypoints, which are presented in equator coordinate system and horizontal one. For locating the waypoints on the GCT, the rotation transformation is introduced to derive the governing equations for the computation procedures with respect to …

Daugherty Water for Food Global Institute: Faculty Publications

The challenges of global agriculture have been analysed exhaustively and the need has been established for sustainable improvement in agricultural production aimed at food security in a context of increasing pressure on natural resources. Whereas the importance of R&D investment in agriculture is increasingly recognised, better allocation of limited funding is essential to improve food production. In this context, the common and often large gap between actual and attainable yield is a critical target. Realistic solutions are required to close yield gaps in both small and large scale cropping systems worldwide; to make progress in this direction, we need (1) …

The Epistemological Basis Of Engineering, And Its Reflection In The Modern Engineering Curriculum, Mike Murphy, William Grimson Jan 2015

The Epistemological Basis Of Engineering, And Its Reflection In The Modern Engineering Curriculum, Mike Murphy, William Grimson

Books/Book chapters

Perhaps unlike other professions, engineering is strangely difficult to define or describe. This is nowhere as evident as when an attempt is made to articulate its epis-temological basis. Engineering has a rich and complex ‘gene pool’ which goes back to when people first built shelters and shaped implements for agricultural purposes. Throughout the ages one constant characteristic of engineering has been its readiness to avail of whatever material is on hand together with whatever knowledge or skill is available to meet the challenge of enhancing an object or making something which nev-er previously existed. On occasion engineers have created new …

Multiplexed Loop-Mediated Isothermal Amplification Of The 16s Rrna Gene For The Diagnosis Of Neonatal Sepsis In Resource-Limited Environments, Griffin T. Sonaty Jan 2015

Multiplexed Loop-Mediated Isothermal Amplification Of The 16s Rrna Gene For The Diagnosis Of Neonatal Sepsis In Resource-Limited Environments, Griffin T. Sonaty

Inquiry: The University of Arkansas Undergraduate Research Journal

Sepsis, or dysregulated inflammation caused by bacterial infection, places a disproportionately high burden on newborns in developing countries. This is due in part to a lack of diagnostic tools suitable for sustainable use in resource-limited nurseries. One potential vehicle for a new diagnostic assay is loop-mediated isothermal amplification (LAMP), a high-yield DNA amplification method. LAMP has previously been used to detect genes from single species of bacteria in blood serum samples to aid in sepsis diagnosis. LAMP could be adapted to detect a broad set of bacteria, while retaining a degree of specificity that allows clinicians to begin directed antimicrobial …
