The Impact Of National Science Foundation Investments In Undergraduate Engineering Education Research: A Comparative, Mixed Methods Study, Jeremi Shavonda London

Open Access Dissertations

The U.S. invests billions of taxpayers' dollars in research tied to the national priorities that contribute to its competitiveness in a global economy. As the federal funding agency with an explicit focus on engineering education, the National Science Foundation (NSF) contains a portfolio of projects focused on improving the quantity of engineering graduates and the quality of engineering programs. Within the agency, the Division of Undergraduate Education invests approximately $190 million (FY 2012) annually on science, technology, engineering and mathematics (STEM) education projects. Although the DUE portfolio includes a suite a projects with different foci supporting national initiatives and Principal …

Assessment Of Policies For Innovative Financing In Infrastructure Systems, Ali Mostafavi, Dulcy Abraham, Charlene Sullivan

Infrastructure System-of-Systems (I-SoS ) Research Group

Infrastructure systems are drivers of the economy in the nation. A dollar spent on infrastructure development yields roughly double the initial spending in ultimate economic output in the short term; and over a twenty-year period, and generalized ‘public investment’ produces an aggregated $3.21 of economic activity per $1.00 spent [1]. Thus, formulation of policies pertaining to infrastructure investment and development is of significance affecting the social and economic wellbeing of the nation. The aim of this policy brief is to evaluate innovative financing in infrastructure systems from two different perspectives: (1) through consideration of the current condition of infrastructure in …

River Basin Management In The Twenty-First Century:Understanding People And Place, Victor Roy Squires Dr

Victor Roy Squires Dr

The book is written by leading authorities on the current and latent issues relating to river basin management (RBM) and brings to the reader an up to date analysis and provides a window into this important subject. A key aspect of the work is that of achieving balance. Technical approaches can address some issues such as hydropower generation, flood mitigation, provision of water for irrigated agriculture to feed burgeoning populations, recreation and navigation, etc. but balancing these is the negotiated outcome of social processes. Ultimately it is these social processes that are the hard part, and often the stumbling block, …

Reduction Of Transportation Greenhouse Gas Emissions To Mitigate Climate Change Impacts, Mary Snow, Richard Snow

Publications

Weather affects almost all modes of transportation in a modern society, and likewise, transportation has an enormous impact on the weather. Transportation greenhouse gas emissions (GHG) impact climate change, which impacts transportation in return. Reduction of transportation impacts on climate change can mitigate the reverse climate change impacts on transportation. This paper examines the relationship between transportation and climate change and establishes prospective solutions to reduce transportation greenhouse gas emission impacts on climate change and mitigate the reverse climate change impacts on transportation.

The Occurrence, Fate, Environmental Impact, And Management Implications Of Pharmaceutical And Personal Care Products In Wastewater And The Environment, Benjamin Donald Blair

Theses and Dissertations

Pharmaceuticals and personal care products (PPCPs) are a critical part of modern life. However, there is growing evidence that the levels of PPCPs detected in wastewater effluent and in the environment have the potential to cause damage to aquatic organisms. These pollutants enter the aquatic environment primarily through human use, disposal in the drain or toilet, land application of biosolids, and veterinary sources. Numerous questions remain regarding the occurrence, fate, and impacts of PPCPs in wastewater, along with limited feasible management recommendations that would adequately mitigate the risk from these pollutants. This dissertation will present three advances in the field …

Models And Solution Algorithms For Asymmetric Traffic And Transit Assignment Problems, Donghyung Yook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Generally, modeling is a simplified representation of the real world; however, this research adds value to the modeling practice by investigating the asymmetric interactions observed in the real world in order to explore potential improvements of the transportation modeling. The enhanced representation of the transportation system by the asymmetric transportation equilibrium problem is promising because there are various asymmetric interactions in real transportation such as intersections, highway ramps, toll roads and in the structure of the transit fares.

The dissertation considers the asymmetric interactions of flows in the traffic and transit assignment problems with an efficient solution algorithm. The study …

Wetland Issues Affecting Waterfowl Conservation In North America, Heath M. Hagy, Scott C. Yaich, John W. Simpson, Eduardo Carrera, David A. Haukos, W.Carter Johnson, Charles R. Loesch, Fritz A. Reid, Scott E. Stephens, Ralph W. Tiner, Brett A. Werner, Greg S. Yarris

Natural Resource Management Faculty Publications

This paper summarises discussions by invited speakers during a special session at the 6th North American Duck Symposium on wetland issues that affect waterfowl, highlighting current ecosystem challenges and opportunities for the conservation of waterfowl in North America. Climate change, invasive species, U.S. agricultural policy (which can encourage wetland drainage and the expansion of row-crop agriculture into grasslands), cost and competition for water rights, and wetland management for non-waterfowl species were all considered to pose significant threats to waterfowl populations in the near future. Waterfowl populations were found to be faced with significant threats in several regions, including: the Central …

Ppdcp-Abe: Privacy-Preserving Decentralized Ciphertext-Policy Attribute-Based Encryption, Jinguang Han, Willy Susilo, Yi Mu, Jianying Zhou, Man Ho Au

Faculty of Engineering and Information Sciences - Papers: Part A

Cipher-policy attribute-based encryption (CP-ABE) is a more efficient and flexible encryption system as the encryptor can control the access structure when encrypting a message. In this paper, we propose a privacy-preserving decentralized CP-ABE (PPDCP-ABE) scheme where the central authority is not required, namely each authority can work independently without the cooperation to initialize the system. Meanwhile, a user can obtain secret keys from multiple authorities without releasing his global identifier (GID) and attributes to them. This is contrasted to the previous privacy-preserving multi-authority ABE (PPMA-ABE) schemes where a user can obtain secret keys from multiple authorities with them knowing his …

An Adaptively Cca-Secure Ciphertext-Policy Attribute-Based Proxy Re-Encryption For Cloud Data Sharing, Kaitai Liang, Man Ho Au, Willy Susilo, Duncan Wong, Guomin Yang, Yong Yu

Faculty of Engineering and Information Sciences - Papers: Part A

A Ciphertext-Policy Attribute-Based Proxy Re-Encryption (CP-ABPRE) employs the PRE technology in the attribute-based en- cryption cryptographic setting, in which the proxy is allowed to convert an encryption under an access policy to another encryption under a new access policy. CP-ABPRE is applicable to many real world applications, such as network data sharing. The existing CP-ABPRE systems, how- ever, leave how to achieve adaptive CCA security as an interesting open problem. This paper, for the rst time, proposes a new CP-ABPRE to tackle the problem by integrating the dual system encryption technology with selective proof technique. The new scheme supports any …
