Honduras wastewater treatment : chemically enhanced primary treatment and sustainable secondary treatment technologies for use with Imhoff tanks
(Massachusetts Institute of Technology, 2009)
(cont.) However, it is doubtful the costs associated with dosages required to achieve these removals are sustainable for communities such as Las Vegas. To address these deficiencies further sustainable practices for ...
Monitoring effective use of household water treatment and safe storage technologies in Ethiopia and Ghana
(Massachusetts Institute of Technology, 2009)
Household water treatment and storage (HWTS) technologies dissemination is beginning to scale-up to reach the almost 900 million people without access to an improved water supply (WHO/UNICEF/JMP, 2008). Without well-informed ...
Applying "Design for Disassembly" to connection design in steel structures
(Massachusetts Institute of Technology, 2009)
Design for Disassembly (DfD), also known as Design for Deconstruction, is an emerging initiative of sustainable construction that favors disassembly over demolition, considering a building's full life cycle during the ...
Sustainable transport at MIT : improving area bus services
(Massachusetts Institute of Technology, 2009)
Everyday each member of the MIT community makes a decision about how they will travel to school or work. Using the Commuter Habit Survey and information regarding local bus services as guides, this report analyzes the ...
Stochastic optimization of hydroelectric dam operations on the Biobio River in Chile
(Massachusetts Institute of Technology, 2009)
Growing electricity demand in Chile has prompted the proposal of new hydropower projects. In addition to evaluating new projects to satisfy demand, a holistic assessment of alternatives as well as potential gains from ...
The design and retrofit of buildings for resistance to blast-induced progressive collapse
(Massachusetts Institute of Technology, 2009)
In recent years, concern has risen drastically regarding the suitability of structural design for blast resistance. Historic events have proven that buildings that are designed in compliance with conventional building codes ...
Bacteria attenuation modeling and source identification in Kranji Catchment and Reservoir
(Massachusetts Institute of Technology, 2009)
This study was performed to determine the bacterial loading of Kranji Catchment and Reservoir and how this will affect planned recreational use of Kranji Reservoir. Field and laboratory work was conducted in Singapore ...
Siphon filter assessment for Northern Ghana
(Massachusetts Institute of Technology, 2009)
The siphon filter is a household water filter developed by the Basic Water Needs Foundation based on the design of ceramic candle filters. The siphon filter is marketed under brand names CrystalPur and Tulip and is sold ...
Carbon nanotubes and their application to very long span bridges
(Massachusetts Institute of Technology, 2009)
Spanning long distances in bridge construction relies mainly on the structure's efficiency and materials used. Whereas structural design for high rise building is fast-expanding, the overall design of long span bridges has ...
Passive motion control of super tall buildings : tuned mass and viscous dampers in Taipei 101.
(Massachusetts Institute of Technology, 2009)
As tall buildings keep becoming taller, they become more susceptible to dynamic excitations such as wind and seismic excitations. One way to reduce structural vibration under dynamic excitations is by placing damping devices ...
