B-slack Trees: Space Efficient B-Trees

B-slack trees, a subclass of B-trees that have substantially better worst-case space complexity, are introduced. They store n keys in height O(logb n), where b is the maximum node degree. Updates can be performed in O(log b 2 n) amortized time. A relaxed balance version, which is well suited for concurrent implementation, is also presented.

Shape control of slack space reflectors using modulated solar pressure.

The static deflection profile of a large spin-stabilized space reflector because of solar radiation pressure acting on its surface is investigated. Such a spacecraft consists of a thin reflective circular film, which is deployed from a supporting hoop structure in an untensioned, slack manner. This paper investigates the use of a variable reflectivity distribution across the surface to control ...

Braiding With Majorana Fermions

This paper is an introduction to relationships between topology, quantum computing and the properties of fermions. In particular we study the remarkable unitary braid group representations associated with Majorana fermions.
