The design and performance of deep excavations in clay
(Massachusetts Institute of Technology, 1997) -
Design and performance of hemostatic biomaterials for managing hemorrhaging
(Massachusetts Institute of Technology, 2018)The high mortality rates associated with uncontrolled bleeding motivate hemostatic material development for traumatic injuries. Uncontrolled, or hemorrhagic, internal bleeding requires hemostatic materials that can be ... -
Design and performance of Thomas Telford's Bonar Bridge and Mythe Bridge
(Massachusetts Institute of Technology, 2018)This paper assesses two cast-iron arch bridges of Thomas Telford (1757-1834) - Bonar Bridge (1810-12) and Mythe Bridge (1824-26) - to draw a broader conclusion about his career in bridge building. The bridges are introduced ... -
Design and potential clinical impact of a noninvasive thermal diffusion sensor to monitor human peripheral microvascular perfusion in real-time
(Massachusetts Institute of Technology, 2006)Perfusion in peripheral tissues is fundamental to the characterization of both local and global cardiovascular health. However, despite the inherent accessibility of tissues such as skin to microvascular measurements, there ... -
Design and process optimization of a hot embossing machine for microfluidics with high aspect ratios
(Massachusetts Institute of Technology, 2013)Microfluidics is a growing technology in the field of medical diagnostics. Daktari Diagnostics is a startup located in Cambridge, MA that seeks to introduce a lab-on-a-chip device for monitoring HIV in patients. This work ... -
Design and process solutions for decreasing vendor defects
(Massachusetts Institute of Technology, 2013)Why do some new initiatives fail while others succeed? This thesis attempts to answer this complex question by investigating the failure of a defect tracking initiative at Amazon and examining how a reintroduction of the ... -
Design and process/measurement for immersed element control in a reconfigurable vertically falling soap film
(Massachusetts Institute of Technology, 2007)Reinforcement learning has proven successful at harnessing the passive dynamics of underactuated systems to achieve least energy solutions. However, coupled fluid-structural models are too computationally intensive for ... -
Design and production of a prototype wheeled pendulum for the new 2.004 laboratory
(Massachusetts Institute of Technology, 2006)The goal of this thesis was to create a piece of physical hardware that would be suited for a multi-week design project for the design component of the Dynamics and Control II (M.I.T. course number: 2.004) laboratory. The ... -
Design and prototype : a manufacturing system for the soft lithography technique
(Massachusetts Institute of Technology, 2006)Ever since 1998 when the term "soft lithography" was first created, soft lithography techniques have drawn close attention of the academia and the industry. Micro contact printing is by far the most widely used soft ... -
Design and prototype fabrication of a manipulator for semiconductor test equipment
(Massachusetts Institute of Technology, 1996) -
Design and prototype of a hovering ornithopter based on dragonfly flight
(Massachusetts Institute of Technology, 2007)Hovering is normally achieved using a horizontal wing path to create lift; bees, wasps and helicopters use this technique. Dragonflies hover using a unique method, by flapping along an inclined stroke plane. This seems to ... -
Design and prototype of a lamp build kit for STEM education
(Massachusetts Institute of Technology, 2016)This thesis describes a case study of an early phase product design process. Company J is a startup toy company creating toys that encourage STEM education and participation. One product in their anticipated lineup is a ... -
Design and prototype of a partial window replacement to improve the energy efficiency of 90-year-old MIT buildings
(Massachusetts Institute of Technology, 2007)The existing windows of the 90-year-old buildings on the main MIT campus are not energy efficient and compromise comfort levels. The single panes of glass allow too much heat transfer and solar heat gain. In addition, the ... -
Design and prototype of a personal ascending device based on the principle of a capstan winch
(Massachusetts Institute of Technology, 2014)The consumer market currently offers no options for a low-cost, personal ascending device. The purpose of this project is to propose a powered ascender, actuated by common power tool components and operating on the principle ... -
Design and prototype of an automated system for commercially viable production using micro contact printing
(Massachusetts Institute of Technology, 2006)This dissertation is a documentation of the thought process, its justification and the implementation details that went into prototyping a fully automated system employing Micro Contact Printing, an emerging technique for ... -
Design and prototype of an object-relational database for medical imaged
(Massachusetts Institute of Technology, 1998)Current electronic patient medical records are based on relational databases that have been very successful in managing text-based information. Recently, however, complex data types, such as digitized images, are becoming ... -
Design and prototype of dual loop lubricant system to improve engine fuel economy, emissions, and oil drain interval
(Massachusetts Institute of Technology, 2015)Regulations aimed at improving fuel economy and reducing harmful emissions from internal combustion engines place constraints on lubricant formulations necessary for controlling wear and reducing friction. Viscosity reduction ... -
