The F-theory geometry with most flux vacua
(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 ... -
Fab forms: customizable objects for fabrication with validity and geometry caching
(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: Toward Flow-aware Buffer Sharing on Programmable Switches
(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 ... -
