Dronenet: The Quad Chronicles
A complex electrical engineering project, Dronenet, is a design and system integration of four major subsystems: an unmanned aerial vehicle (UAV), a control terminal for the UAV, a mobile UAV carrier, and a control terminal for the mobile UAV carrier. Dronenet has a unique regenerative charging system based on the design of a Bedini motor to extend the duration of Pb and LiPo batteries. This pr...
متن کاملBackground for the Quad Prize
The a Quad Prize, to be awarded in coordination with the Automata-2008 workshop, wants to encourage filling a gap in our imagination of the simplest models of computation, and will be awarded to the first submission that will either exhibit a computation-universal 2-state cellular automaton on a 2-dimensional, 2×2-neighborhood—or on the contrary prove that none exist within that class. Short of...
متن کاملThe Quad-Arc Data Structure
In Gold et al. (1996) a simple polygon digitizing technique was described where ‘fringe’ points were digitized around the interior of each map polygon, the Voronoi diagram constructedand the relevant polygon boundary segments extracted from the Voronoi cells. Gold (1997a) extended this to work with scanned map input, where the fringe points were generated automatically, and complete polygon bou...
متن کاملAdaptive Quad Mesh Simplification
We present an improved algorithm for the progressive simplification of quad meshes, which adapts the resolution of the mesh to details of the modeled shape. We extend previous work [TPC∗10], by simplifying the approach and combining it with the concept of Fitmaps introduced in [PPT∗10]. The new algorithm has several advantages: it is simpler and more robust; it does not need a parametrization o...
متن کاملAnalysis of QUAD
In a Eurocrypt 2006 article entitled “QUAD: A Practical Stream Cipher with Provable Security,” Berbain, Gilbert, and Patarin introduced QUAD, a parametrized family of stream ciphers. The article stated that “the security of the novel stream cipher is provably reducible to the intractability of the MQ problem”; this reduction deduces the infeasibility of attacks on QUAD from the hypothesized inf...
