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 ... -
Identification of design requirements for a high-performance, low-cost, passive prosthetic knee through user analysis and dynamic simulation
(Massachusetts Institute of Technology, 2013)In January 2012, a partnership was initiated between the Massachusetts Institute of Technology and Bhagwan Mahaveer Viklang Sahayata Samiti (BMVSS, a.k.a., Jaipur Foot) to design a high-performance, low-cost, passive ... -
Improving Indian beehives and beekeeping
(Massachusetts Institute of Technology, 2016)This thesis explores five beekeeping topics from a mechanical engineering perspective with findings that are relevant for both Indian and American beekeepers. First, hive weight scale mechanisms are quantitatively analyzed, ... -
An integrated modeling and decision tool for improved drinking water reliability in rural villages of India
(Massachusetts Institute of Technology, 2015)Rural community, which constitutes more than 70% of the total population in India, faces an everyday struggle to meet basic water requirements. The challenges in this struggle are numerous: lack of infrastructure, limited ... -
Justification of village scale photovoltaic powered electrodialysis desalination systems for rural India
(Massachusetts Institute of Technology, 2014)This thesis justifies photovoltaic (PV)-powered electrodialysis (ED) as an energy and cost-effective means of desalinating groundwater in rural India and presents the design requirements for a village-level system. Saline ... -
Method for Turbocharging Single Cylinder Four Stroke Engines
(ASME International, 2014-08)This paper presents a feasibility study of a method for turbocharging single cylinder, four-stroke internal combustion engines. Turbocharging is not conventionally used with single cylinder engines because of the timing ... -
A methodology for turbocharging single cylinder four stroke internal combustion engines
(Massachusetts Institute of Technology, 2015)This thesis presents a method for turbocharging single cylinder four stroke internal combustion engines, a model used to evaluate it, an experimental setup used to test it, and the findings of this experiment. A turbocharged ... -
National rural drinking water monitoring: progress and challenges with India's IMIS database
(IWA Publishing, 2016-02)National drinking water programs seek to address monitoring challenges that include self-reporting, data sampling, data consistency and quality, and sufficient frequency to assess the sustainability of water systems. India ... -
Pathways of industrialization exploring the impact of policy on industrial growth and urbanization in India
(Massachusetts Institute of Technology, 2016)Industrialization is the process in which a primarily agricultural area transforms into one centered around manufacturing goods and services. It occurs after the relocation of a large industrial plant to a previously rural ... -
Point-of-use soil diagnostics : an actionable information system for resource constrained farmers
(Massachusetts Institute of Technology, 2016)During the mid-1960s, India came to the brink of an acute food crisis in the midst of heavy dependence on food imports. A period of rapid agricultural modernization that followed, known as Green Revolution, transformed ... -
The reference electrification model : a computer model for planning rural electricity access
(Massachusetts Institute of Technology, 2015)Despite efforts from governments and other organizations, hundreds of millions of people-primarily in Africa and South Asia-still have no electricity service. Electrification efforts have historically been focused on ... -
Removal rates of electrolytes commonly found in brackish groundwater by means of electrodialysis reversal desalination
(Massachusetts Institute of Technology, 2015)This thesis tested and analyzed the removal rates of six different electrolytes: NaCl, Na2SO4 , MgCl2 , K2SO4 , Ca(NO3 )2, and CaSO4 when using electrodialysis reversal (EDR) desalination. A bench top EDR set-up was designed ... -
The role of actors and incentives in municipal solid waste management : a case study on Muzaffarnagar, India
(Massachusetts Institute of Technology, 2015)The ever-increasing urban population and a growing middle class are leading to a burgeoning solid waste problem in Indian cities. While legislation has been passed to address the growing waste issue, there has been limited ... -
