Effects Of Time Varying Background Noise Conditions On Human Perception And Performance, Andrew H. Hathaway

Architectural Engineering -- Dissertations and Student Research

This thesis was designed to study the effects of changing noise conditions on human perception and performance. In two phases, participants were exposed to a number of noise conditions and their performance on an arithmetic task involving short-term memory was monitored and their subjective perception of noise conditions was collected via questionnaires.

In the first phase, participants were tested while being subjected to RC-29(H) and RC-47(RV) conditions created by broadband noise fluctuating on different time intervals, resembling the changing noise conditions potentially found in modern HVAC systems. These intervals varied from two minutes to ten minutes. Results show ...

Improving Scheduling In Heterogeneous Grid And Hadoop Systems, Aysan Rasooli Oskooei

Open Access Dissertations and Theses

Advances in network technologies and computing resources have led to the deployment of large scale computational systems, such as those following Grid or Cloud architectures. The scheduling problem is a significant issue in these distributed computing environments, where a scheduling algorithm should consider multiple objectives and performance metrics. Moreover, heterogeneity is increasing at both the application and resource levels. The heterogeneity in these systems can have a huge impact on performance in terms of metrics such as average completion time. However, traditional Grid and Cloud scheduling algorithms neglect heterogeneity in their scheduling decisions. This PhD dissertation studies the scheduling challenges ...

A Model For Transforming Engineering Education Through Group Learning, Shannon Chance, Gavin Duffy, Brian Bowe, Mike Murphy, Tony Duggan

Conference papers

Electrical engineering educators at Dublin Institute of Technology (DIT) have successfully implemented pedagogical change. They now use group-based, student-centered and inquiry-driven approaches to teach emerging engineers. The objective of this was to foster students’ personal as well as professional skills (i.e., teamwork, communication, self-directed learning, etc.). This paper explores how such change was achieved and provides graphic models that draw from prior phenomenological studies and incorporates aspects of Rogers’ (1962) product adoption curve and Lowe’s (2012) interpretations of it.

Investigation Of Sound Transmission Through An Open Window Into A Room, Caleb F. Sieck

Architectural Engineering -- Dissertations and Student Research

In recent decades, noise levels in cities and the associated annoyance and health consequences have become regular topics of discussion. As a result, the assessment of environmental noise transmitting into buildings has received much attention. Current models of sound transmission through open windows have either neglected their thickness or the presence of a room behind on one side. The objectives of the present work were to (1) develop an accurate analytical model of sound transmission through an open window of finite thickness into a room, (2) verify the analytical model using a finite element model and experimental measurements, and (3 ...

Aqueous Turbulence Structure Immediately Adjacent To The Air - Water Interface And Interfacial Gas Exchange, Binbin Wang

Theses and Dissertations

Air-sea interaction and the interfacial exchange of gas across the air-water interface are of great importance in coupled atmospheric-oceanic environmental systems. Aqueous turbulence structure immediately adjacent to the air-water interface is the combined result of wind, surface waves, currents and other environmental forces and plays a key role in energy budgets, gas fluxes and hence the global climate system. However, the quantification of turbulence structure sufficiently close to the air-water interface is extremely difficult. The physical relationship between interfacial gas exchange and near surface turbulence remains insufficiently investigated. This dissertation aims to measure turbulence in situ in a complex environmental ...

Comparing Class A Compressed Air Foam Systems (Cafs) Against Plain Water Suppression In Live Fire Gas Cooling Experiments For Interior Structural Firefighting, Sean Carter Mitchell

Master's Theses and Project Reports

Wildland fire services have successfully integrated compressed air foam systems (CAFS) into their fire suppression arsenal over the last few decades to effectively increase the firefighting ability of water. Many urban fire departments have done the same, but far more still rely on plain water to extinguish Class A fires. Many claims have been made about the advantages and disadvantages of firefighting foams, but only limited research has been conducted on the subject to date. Fire departments need more information, beyond that provided by foam suppliers and CAFS equipment manufacturers, to make an independent decision on whether or not to ...
