      Recent studies have shown that distributed spacecraft missions, or constellations, can offer similar performance to monolithic satellite missions for lower cost and less risk. Additionally, recent developments in and ...
    • PCV valve flutter : vibration characterization through pressure and flow 

      Gomez, Nicasio (Massachusetts Institute of Technology, 2005)
      A Positive Crankcase Ventilation, or PCV, valve is required by internal combustion engines in order to regulate the flow of blow-by gases out of the crankcase and into the intake air stream. Fluctuations in the pressure ...
    • Peak pressures due to steam bubble collapse-induced water hammer 

      Perkins, Garry Wayne. (Massachusetts Institute of Technology, 1979)
    • Peanut oil press for developing countries 

      Jain, Neera, S.B. Massachusetts Institute of Technology; Lee, Somin (Massachusetts Institute of Technology, 2006)
      Despite the problems with obesity that the United States is facing today, malnutrition, caused in part by severely low dietary fat consumption, remains a problem among many people living in Sub-Saharan Africa. According ...
    • Peanut oil press redesign for Developing countries 

      Lee, Daipan (Massachusetts Institute of Technology, 2007)
      One of the causes of malnutrition among the rural inhabitants of Sub-Saharan Africa is the high cost of dietary fats that are necessary to maintain normal body functions. Though the Food and Agriculture Organization of the ...
    • Peluchi : product development of a programmable robotic toy to stimulate interest in the fields of science and technology amongst young girls 

      Vu, My (My H.) (Massachusetts Institute of Technology, 2011)
      Statistically speaking, science, technology, and engineering are male dominated fields. Peluchi is a second-generation prototype of a programmable robotic toy targeted towards young girls in hope of promoting more interest ...
    • The performance of a diesel engine using benzol as a fuel, 

      Hickey, Thomas R; Stephenson, Thomas I (Massachusetts Institute of Technology, 1945)
    • Performing overhead tasks with supernumerary robotic limbs 

      McKenna, Jay (Jay P.) (Massachusetts Institute of Technology, 2014)
      Overhead tasks such as those frequently found in aircraft manufacturing pose health risks to the workers due to the strain imposed on the shoulders. To reduce the risk of injury, a set of supernumerary robotic limbs (SRL) ...
