Factors Impacting The Cultivation, Structure, And Oxygen Profiles Of Oxygenic Photogranules For Aeration-Free Wastewater Treatment, Megan Hann 2018 University of Massachusetts Amherst

Factors Impacting The Cultivation, Structure, And Oxygen Profiles Of Oxygenic Photogranules For Aeration-Free Wastewater Treatment, Megan Hann

Environmental & Water Resources Engineering Masters Projects

Oxygenic photogranules (OPGs) are novel biogranules which have successfully treated wastewater without external aeration at the bench scale. The formation of OPGs under both static and hydrodynamic conditions is a unique phenomenon which has no known counterpart. This report examines some of the granulation mechanisms and structural and functional differences between statically and hydrodynamically cultivated OPGs. As previously reported, filamentous cyanobacteria are an essential component of both types of OPGs. The addition of Oscillatoria in augmented activated sludge inoculum showed successful static OPG formation in a shorter time (28 vs 35 days) and produced more settled OPGs than native sludge ...

Implications Of Data Sampling Resolution On Water Use Simulation, End-Use Disaggregation, And Demand Management, A. Cominola, M. Giuliani, A. Castelletti, David E. Rosenberg, A. M. Abdallah

Civil and Environmental Engineering Faculty Publications

Understanding the tradeoff between the information of high-resolution water use data and the costs of smart meters to collect data with sub-minute resolution is crucial to inform smart meter networks. To explore this tradeoff, we first present STREaM, a STochastic Residential water End-use Model that generates synthetic water end-use time series with 10-s and progressively coarser sampling resolutions. Second, we apply a comparative framework to STREaM output and assess the impact of data sampling resolution on end-use disaggregation, post meter leak detection, peak demand estimation, data storage, and meter availability. Our findings show that increased sampling resolution allows more accurate ...

Gender Difference In Situation Awareness When Receiving Wayfinding Direction By Landmarks And Headings, Ziyi Dong 2018 Embry-Riddle Aeronautical University

Gender Difference In Situation Awareness When Receiving Wayfinding Direction By Landmarks And Headings, Ziyi Dong

Dissertations and Theses

In aviation, situation awareness (SA) is a fundamental requirement for effective flying and air traffic control. This skill has greatly been associated with pilot and air traffic controller performance. Previous studies in aviation and other fields have shown that gender differences exist in SA performance. Four hypotheses were tested in this study: women navigate better from landmark cues; men navigate better from headings cues; women have better SA performance than men when receiving landmark directions; and men have better SA when receiving cardinal directions. Thirty-eight participants drove a driving simulator twice. While driving, participants were asked SA questions to assess ...


Integrated Free-Form Method For Aerostructural Optimization Of Wind Turbine Blades, Ryan Barrett, Andrew Ning 2018 Brigham Young University

Integrated Free-Form Method For Aerostructural Optimization Of Wind Turbine Blades, Ryan Barrett, Andrew Ning

All Faculty Publications

A typical approach to optimize wind turbine blades separates the airfoil shape design from the blade planform design. This approach is sequential, where the airfoils along the blade span are pre-selected or optimized and then held constant during the blade planform optimization. In contrast, integrated blade design optimizes the airfoils and the blade planform concurrently and thereby has the potential to reduce cost of energy (COE) more than sequential design. Nevertheless, sequential design is commonly performed because of the ease of precomputation, or the ability to compute the airfoil analyses prior to the blade optimization. This research compares two integrated ...

Implementation Of 5s At A Survey Laboratory In Western Kentucky University, Mercy Akunna Ebuetse 2018 Western Kentucky University

Implementation Of 5s At A Survey Laboratory In Western Kentucky University, Mercy Akunna Ebuetse

Masters Theses & Specialist Projects

5S is a technique used alongside methodologies such as lean, total quality management and six-sigma for continuous improvement and workplace standardization. Nonetheless, despite the upsurge in the implementation of 5S by lean manufacturing facilities and other industries, educational laboratories appear to be lagging. Taking into consideration the benefits of implementing 5S within industry, it has become crucial to replicate the technique in an educational laboratory to obtain equivalent results. To upgrade educational laboratories into industrial laboratories, 5S (sort, set in order, shine, standardize, and sustain) is required to improve the laboratory’s ergonomics that subsequently increases efficiency, productivity, and lessens ...

The Skilled Framing Carpenter Shortage On The Central Coast Of California: A Focus On Residential Construction, Trevor John Nally

Construction Management

The residential construction industry has many critical components. When one of these components is not operating optimally, it can be detrimental to the system as a whole. A critical component to residential construction is skilled craftspeople. Without them, there can be no significant physical work completed on any residential project. Currently the component of skilled craftspeople in residential construction is in a state of short supply. Throughout the United States, there is an inadequate amount of craftspeople to fill the demand for their skills. The Central Coast of California is experiencing this issue much like the rest of the nation ...
