Compost marketing guidelines for solid municipal waste management in India
(Massachusetts Institute of Technology, 2015)India has a waste problem. With the world's second largest population at 1.252 billion individuals, a population density of 382 persons per square kilometer and consumer behavior demanding a higher standard of life and ... -
Confined masonry for seismically resilient low-cost housing in India : a design and analysis method
(Massachusetts Institute of Technology, 2015)Confined masonry (CM) is a viable housing typology that is resilient and economical for developing countries in seismic regions. Given its suitability for low-tech environments, multiple authors have published instructions ... -
Delivering a low-cost, reliable drip irrigation filtration system for micro-irrigation in developing countries
(ASME International, 2014-08)The cylindrical filters presently used in drip irrigation systems frequently clog, increasing pressure loss and lowering the flow rate through the filters. This work investigates alternative filtration strategies that ... -
Design and evaluation of a cantilever beam-type prosthetic foot for Indian persons with amputations
(Massachusetts Institute of Technology, 2014)The goal of this work is to design a low cost, high performance prosthetic foot in collaboration with Bhagwan Mahaveer Viklang Sahayata Samiti (BMVSS), in Jaipur, India. In order to be adopted, the foot must cost less than ... -
Development of a Design Tool for Flow Rate Optimization in the Tata Swach Water Filter
(ASME International, 2014-08)When developing a first-generation product, an iterative approach often yields the shortest time-to-market. In order to optimize its performance, however, a fundamental understanding of the theory governing its operation ... -
Development of an efficient off-grid pumping system and evaporation reduction strategies to increase access to irrigation for smallholder farmers in India
(Massachusetts Institute of Technology, 2013)Due to the unavailability of electricity, about 85% of groundwater irrigation in eastern India employs fuel-powered surface pumps, which can have system efficiencies as low as 5%. As fuel prices continue to rise, impoverished ... -
Droplet deposition on hydrophobic surfaces for agricultural sprays
(Massachusetts Institute of Technology, 2015)This thesis presents a study of the in-situ precipitation of polyelectrolytes during droplet impacts and its applications in enhancing the retention efficiency of sprays. Large amounts of agricultural sprays are wasted ... -
The Effects of Prosthesis Inertial Properties on Prosthetic Knee Moment and Hip Energetics Required to Achieve Able-bodied Kinematics
(Institute of Electrical and Electronics Engineers (IEEE), 2015-07)There is a major need in the developing world for a low-cost prosthetic knee that enables users to walk with able-bodied kinematics and low energy expenditure. To efficiently design such a knee, the relationship between ... -
Effects of Prosthesis Mass on Hip Energetics, Prosthetic Knee Torque, and Prosthetic Knee Stiffness and Damping Parameters Required for Transfemoral Amputees to Walk With Normative Kinematics
(ASME International, 2014-08)We quantify how the hip energetics and knee torque required for an above-knee prosthesis user to walk with the kinematics of able-bodied humans vary with the inertial properties of the prosthesis. We also select and optimize ... -
Environmental and economic tradeoffs in building materials production in India
(Massachusetts Institute of Technology, 2014)The current and projected growth of India's economy and population will continue to lead to increased demand for buildings and infrastructure, and there is a real need to consider what this increase means in terms of natural ... -
Exploring volatile fatty acids (VFAs) as a novel substrate for microbial oil production
(Massachusetts Institute of Technology, 2015)Cost effective production of biofuels depends critically on feedstock cost and availability. As such, volatile fatty acids (VFAs) can play an important role in advancing sustainable biofuel production since they can be ... -
Extending the reach of anterior segment ophthalmic imaging
(Massachusetts Institute of Technology, 2016)Eye exams via a slit lamp are critical in screening for conditions such as cataracts, corneal opacities and pterygia early on to avert vision loss. The slit lamp, however, is a purely qualitative optical device that is ... -
