Performance composability: An emerging challenge in performance-adaptive systems
… performance tuning. Composition of multiple adaptive components in large-scale software systems, however, presents challenges that arise from potential incompatibilities among the respective components. Self-reinforcing “vicious cycles” caused by interactions between them lead to unstable or …

Design and control of a compact aerial manipulation system with a Delta-type parallel robot
… controller, where baseline, feedforward, and adaptive components are combined and used in unison with an optimal trajectory generation algorithm. Finally, we present simulation results which reflect the feasibility of the concepts.

Improving performance for adaptive filtering with voice applications
… OF MISSOURI-COLUMBIA AT AUTHOR'S REQUEST.] Adaptive filtering is a common solution to many signal processing applications in which the environments are time varying. Its performance is limited by the misadjustment. A method to reduce the misadjustment when the additive noise in the desired …

Enabling and directing real-time cognitive radar transmitter optimization.
As the available wireless spectrum grows more crowded with increased usage from high bandwidth telecommunications applications, it becomes infeasible for many other users of wireless spectrum to continue operating with static, inflexible methods. Among these users are radar systems, which have …

Systematic adaptive control design using sequential loop closure
… method of synthesizing an output feedback adaptive controller for a class of uncertain, non-square multi-input/multi-output systems. The control design process consists of first designing an inner-loop controller for a reduced order plant model to enforce command tracking of selected …

A Study of the Effects of Scintillation on Digital Satellite Communication Systems
… fading are discussed. Analysis of an adaptive modulation system using three modulation techniques is presented and its advantages demonstrated. The adaptive system can be used to mitigate scintillation fading and at the same time increase the capacity of the system, decreasing system …

Troubleshooting interactive complexity bugs
… tendency of systems with large number of components. He argued that, in systems with large number of components, multiple failures often interact in some unexpected way, leading to catastrophic failures in systems such as planes or nuclear power plants. He also suggested that with …
