    • F-K Characteristics of the Seismic Response to a Set of Discrete Parallel Fractures 

      Zhang, Yang; Campman, Xander; Grandi, Samantha K.; Chi, Shihong; Toksoz, M. Nafi; e.a. (Massachusetts Institute of Technology. Earth Resources Laboratory, 2006)
      We model seismic wave propagation in a reservoir with discrete fracture zones using a finite difference scheme, which implements the Coates-Schoenberg formulation for fractured media. We study the variation of scattered ...
    • The F-theory geometry with most flux vacua 

      Taylor, Washington; Wang, Yinan (Springer Berlin Heidelberg, 2015-12)
      Applying the Ashok-Denef-Douglas estimation method to elliptic Calabi-Yau fourfolds suggests that a single elliptic fourfold M[subscript max] gives rise to O(10[superscript 272,000]) F-theory flux vacua, and that the ...
    • The F119 Engine: A Success Story of Human Systems Integration in Acquisition

      Ward, Matthew John (Massachusetts Institute of Technology, 2007)
      Intel's Colorado Springs wafer fabrication facility, known internally as F23, has undertaken several initiatives to reduce cycle time including High Precision Maintenance (HPM), content reduction through the application ...
    • Fab forms: customizable objects for fabrication with validity and geometry caching 

      Shugrina, Maria; Shamir, Ariel; Matusik, Wojciech (Association for Computing Machinery (ACM), 2015-08)
      We address the problem of allowing casual users to customize parametric models while maintaining their valid state as 3D-printable functional objects. We define Fab Form as any design representation that lends itself to ...
    • Fab trees for designing complex 3D printable materials 

      Wang, Ye, M. Eng. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2013)
      With more 3D printable materials being invented, 3D printers nowadays could replicate not only geometries, but also appearance and physical properties. On the software side, the tight coupling between geometry and material ...
    • FAB: Toward Flow-aware Buffer Sharing on Programmable Switches 

      Ranjan, Manya (ACM, 2019-12)
      Conventional buffer sizing techniques consider an output port with multiple queues in isolation and provide guidelines for the size of the queue. In practice, however, switches consist of several ports that share a buffering ...
    • Fables of undiscovered cities 

      Bao, Jie, S.M. Massachusetts Institute of Technology (Massachusetts Institute of Technology, 2017)
      "Space... The final frontier... These are the voyages of the Starship Enterprise. Its continuing mission: To explore strange new worlds... To seek out new life; new civilizations... To boldly go where no one has gone ...
