The carbon footprint analysis of wastewater treatment plants and nitrous oxide emissions from full-scale biological nitrogen removal processes in Spain
(Massachusetts Institute of Technology, 2013)
This thesis presents a general model for the carbon footprint analysis of advanced wastewater treatment plants (WWTPs) with biological nitrogen removal processes, using a life cycle assessment (LCA) approach. Literature ...
The dynamic behavior of the Basilica of San Francesco of Assisi
(Massachusetts Institute of Technology, 2013)
During the 1997 Umbria-Marche earthquake, two of the vaults of the Basilica of San Francesco in Assisi collapsed as a result of an 8.5 Mercalli-scale magnitude earthquake. The structure had endured stronger earthquakes for ...
The effects of an intermittent piped water network and storage practices on household water quality in Tamale, Ghana
(Massachusetts Institute of Technology, 2013)
The United Nations Millennium Development Goals include a target to halve the number of people without access to "improved" water sources, which include piped water supply. However, an "improved" source of water does not ...
Near and far field models of external fluid mechanics of Ocean Thermal Energy Conversion (OTEC) power plants
(Massachusetts Institute of Technology, 2013)
The world is facing the challenge of finding new renewable sources of energy - first, in response to fossil fuel reserve depletion, and second, to reduce greenhouse gas emissions. Ocean Thermal Energy Conversion (OTEC) can ...
Control of agricultural nonpoint source pollution in Kranji Catchment, Singapore
(Massachusetts Institute of Technology, 2013)
Singapore's Kranji Reservoir is highly sensitive to nutrient and bacterial pollution, both of which can be directly traced to agricultural runoff. Water quality samples were collected along the main drainage channel in the ...
Increasing supply chain robustness through process flexibility and strategic inventory
(Massachusetts Institute of Technology, 2013)
When a disruption brings down one of company's manufacturing facilities, it can have a ripple effect on the entire supply chain and threaten the company's ability to compete. In this thesis, we develop an effective disruption ...
Evaluation of sewer leakage into the stormwater drainage system in Singapore
(Massachusetts Institute of Technology, 2013)
Singapore's Public Utilities Board (PUB) aspires to bring Singaporeans closer to their water bodies through recreational activities so that they may cherish them and be more conscious of water scarcity. However, there have ...
The relationship between rail transit ridership and built environment and transportation system
(Massachusetts Institute of Technology, 2013)
Public transportation is an effective tool to tackle many urban transportation problems. Due to its higher capacity and reliability, rail transit often serves as the main means to connect major trip origins and destinations ...
Study of base isolation systems
(Massachusetts Institute of Technology, 2013)
The primary objective of this investigation is to outline the relevant issues concerning the conceptual design of base isolated structures. A 90 feet high, 6 stories tall, moment steel frame structure with tension cross ...
Simulation of household in-home and transportation energy use : an integrated behavioral model for estimating energy consumption at the neighborhood scale
(Massachusetts Institute of Technology, 2013)
Household in-home activities and out-of-home transportation are two major sources of urban energy consumption. In light of China's rapid urbanization and income growth, changing lifestyles and consumer patterns - evident ...
