The formulation of hybrid crossing angle schemes has been a recent development of the TESLA collision geometry debate. Here we report on two such schemes, characterised by either a small vertical or horizontal beam crossing angle.

Three hybrid fuzzy control schemes for robotics applications are described. The rst scheme concentrates on a control architecture which incorporates fuzzy logic theory into the framework of behavior control for mobile robot navigation. The second scheme develops a two-level hierarchical fuzzy control structure for exible manipulators. It incorporates Genetic Algorithms (GA) in a learning scheme...

Hybrid information retrieval (IR) schemes combine di erent normalization techniques and similarity functions. Hybrid schemes provide an eÆcient technique to improve precision and recall (see e.g., [4]). This paper reports a hybrid clustering scheme that applies a singular value decomposition (SVD) based algorithm followed by a k{means type clustering algorithm. The output of the rst algorithm b...

This paper expands the notion of a KEM–DEM hybrid encryption scheme to the signcryption setting by introducing the notion of a signcryption KEM, a signcryption DEM and a hybrid signcryption scheme. We present the security criteria that a signcryption KEM and DEM must satisfy in order that the overall signcryption scheme is secure against outsider attacks. We also present ECISS–KEM — a simple, e...

Often authentication and confidentiality are required as simultaneous key requirements in many cryptographic applications. The cryptographic primitive called signcryption effectively implements the same and while most of the public key based systems are appropriate for small messages, hybrid encryption (KEM-DEM) provides an efficient and practical way to securely communicate very large messages...

Optimal control theory is a powerful tool for solving control problems in quantum mechanics, ranging from the control of chemical reactions to the implementation of gates in a quantum computer. Gradient-based optimization methods are able to find high fidelity controls, but require considerable numerical effort and often yield highly complex solutions. We propose here to employ a two-stage opti...

The question of constructing a hybrid signcryption scheme with outside security was considered by Dent [7]. That paper also demonstrated that the basic hybrid construction formalised by Cramer and Shoup [5, 9] is incapable of producing a signcryption scheme with insider security. This paper provides a paradigm for constructing signcryption schemes with insider security based on the ideas of hyb...

Jens-Dominik M uller and Michael B. Giles Oxford University Computing Laboratory Abstract A Navier-Stokes multigrid method that has been developed for triangles and tetrahedra is extended to be used on hybrid grids. Various choices in extending the linear preserving ux calculation of the simplex scheme are discussed and a exible way of expressing edge weights is presented. An edge-collapsing a...
