21. This co-operation never bore fruit despite the secondment of STMicroelectronics Bristol based staff to Quadrics . 22. Equivalently, it is a projective variety, defined as the zero locus of three smooth quadrics . 23. However the linear system of divisors consisting of all such quadrics is not without a base locus. 24. Lie sphere geometry is the geometry of the Lie quadric and the Lie transformations which preserve it. 25. The Linux-based supercomputer is the NetworkX / Quadrics machine at Lawrence Livermore National Laboratories in California. 26. Many high-performance interconnects including Myrinet, Quadrics , IEEE 1355, and SpaceWire support source routing. 27. It is possible to define the Jacobi form of an elliptic curve as the intersection of two quadrics . 28. However, QGA includes vector entities that can represent only the principal axes-aligned quadric surfaces characterized by 29. A powerful feature of QGA is the ability to compute the intersections of axes-aligned quadric surfaces. 30. The usual definition of a conic uses a quadratic form ( see Quadric ( projective geometry ) ).
