Trajectory generation and control for four wheeled omnidirectional vehicles
This paper describes an algorithm to calculate near-optimal minimum time trajectories for four wheeled omnidirectional vehicles, which can be used as part of a high-level path pla...

A Constraint and Attribute Based Security Framework for Dynamic Role Assignment in Collaborative Environments
Abstract. We investigate a security framework for collaborative applications that relies on the role-based access control (RBAC) model. In our framework, roles are pre-defined and...

Selective Magic HPSG Parsing
We propose a parser for constraintlogic grammars implementing HPSG that combines the advantages of dynamic bottom-up and advanced topdown control. The parser allows the user to ap...

Consistent Approximations and Approximate Functions and Gradients in Optimal Control
As shown in [7], optimal control problems with either ODE or PDE dynamics can be solved efficiently using a setting of consistent approximations obtained by numerical discretizati...

Isochronous manifolds in self-triggered control
Abstract— Feedback control laws are predominantly implemented on digital platforms as periodic tasks. Although periodicity simplifies the analysis and design of the implementati...
