Opportunities To Mainstream Gender In Water And Wastewater Infrastructure Projects: A Case Study In Barbados, Wainella Isaacs Mar 2017

Opportunities To Mainstream Gender In Water And Wastewater Infrastructure Projects: A Case Study In Barbados, Wainella Isaacs

Graduate Theses and Dissertations

According to the World Resources Institute, Barbados is one of seven Caribbean countries ranked as being the most water stressed territories in the world. Prevailing drought conditions for the period 2010-2016 further compromised its water security while confirming predictions of a drier regional Caribbean climate. The simultaneous failing of at least 50-year-old water infrastructure at many points in the distribution network adds to these water stress conditions, and presents a financial burden to the local water utility in the form of lost revenues, and increased energy consumption for pumping.

Climate change and its impacts are not gender-neutral, and water infrastructure ...


Automated Design For Manufacturing And Supply Chain Using Geometric Data Mining And Machine Learning, Michael Jeffrey Daniel Hoefer Jan 2017

Automated Design For Manufacturing And Supply Chain Using Geometric Data Mining And Machine Learning, Michael Jeffrey Daniel Hoefer

Graduate Theses and Dissertations

This thesis presents an automated method for assessing conceptual designs with respect to manufacturing and supply chain, using geometric data mining and machine learning algorithms. It is important for designers to understand how design decisions will impact downstream manufacturing and sourcing. Many critical decisions are made during conceptual design that impact production cost even before detailed design is finalized; however, the effects of these decisions are not known until later. Design for manufacturing and design for supply chain are methods that provide feedback to the user in a way that enables proactive design changes.

A High-Fidelity Approach To Conceptual Design, John Thomas Watson Jan 2016

A High-Fidelity Approach To Conceptual Design, John Thomas Watson

Graduate Theses and Dissertations

We created a new methodology to perform conceptual design analysis on aircraft, using off-the-shelf, high-fidelity software tools to explore the project design space, including important preliminary design factors and thereby producing a more robust result which is less subject to compromise at later design stages. We claim that this analysis can be performed in one hour with commonly available computation resources, and therefore is applicable to conceptual design. We used the case study of a supersonic transport jet to develop these methods. For this application, we used Solidworks to create a parameterized three-dimensional CAD solid to define the exterior geometry ...


Surrogate-Based Design Optimization Of Dual-Rotor Wind Turbines Using Steady Rans Equations, Andrew Scott Thelen Jan 2016

Surrogate-Based Design Optimization Of Dual-Rotor Wind Turbines Using Steady Rans Equations, Andrew Scott Thelen

Graduate Theses and Dissertations

Dual-rotor wind turbines (DRWT) may offer better energy efficiency over their single-rotor counterparts in isolated and in windfarm operation. The design and analysis of DRWT requires, among other, the use of computational fluid dynamics models. Depending on their formulation, these models can be computationally expensive. Numerous simulations are typically required during the design process, which may render the overall computational cost to be prohibitive. This thesis investigates and compares several optimization techniques for the design of DRWTs. In particular, the DRWT fluid flow is solved using the Reynolds-Averaged Navier-Stokes equations with a two-equation turbulence model on an axisymmetric mesh, while ...

Website Gender Perceptions: Effects And Recommendations For Gender Inclusivity, Jacklin Hope Stonewall Jan 2016

Website Gender Perceptions: Effects And Recommendations For Gender Inclusivity, Jacklin Hope Stonewall

Graduate Theses and Dissertations

This paper examines the interactions of design elements and perceptions of a website’s gender as well as the effects of perceived gender on aspects of user experience. Designing for a particular gender is common in both product and web design, but in many situations is exclusionary. While imparting gender onto a product is often intentional, gender bias in websites largely is not. The unintentional gender bias in websites is created through a combination of internalized biases, biased tools, and culture. This work lays the foundation for understanding how websites become gendered as well as the effects of gendering on ...


Testing Non-Termination In Multi-Threaded Programs, Priyanka Thyagarajan Jan 2016

Testing Non-Termination In Multi-Threaded Programs, Priyanka Thyagarajan

Graduate Theses and Dissertations

We study the problem of detecting non - termination in multi - threaded programs due to unwanted race conditions. We claim that the cause of non-termination can be attributed to the presence of at least two loops in two different threads, where the valuations of the loop controlling parameters are inter-dependent, i.e., value of one parameter in one thread depends on the execution sequence in the other thread and vice versa. In this thesis, we propose a testing based technique to analyze finite execution sequences and infer the likelihood of non-termination scenarios. Our technique is a light weight, flexible testing based ...
