This paper presents learning points from the application of a dynamic thermal rating (DTR) system to a 132kV distribution network. The DTR system incorporates over 90km of 132kV overhead lines and is being deployed to facilitate the connection of in excess of 200 MW of wind generation. The benefits and principles of this DTR system are stated, and initial results from the deployment are presented...
Materials International Space Station Experiment-X (MISSE-X) is a proposed International Space Station (ISS) external platform for space environmental studies designed to advance the technology readiness of materials and devices critical for future space exploration. The MISSE-X platform will expand ISS utilization by providing experimenters with unprecedented low-cost space access and return on investment...
Today operators in complex task domains such as aviation, process control, medicine and the military must work closely with automation to achieve levels of performance that would be impossible to reach independently. To maximize the full benefit of this man-machine relationship operator trust must be appropriately calibrated with the trustworthiness of the system. Misalignment of trust with the automation's...
The productivity of software developers is under constant attack due to a continual inundation of information: source code is easier and easier to traverse and to find, email inboxes are stuffed to capacity, RSS feeds and tweets provide a continual stream of technology updates, and so on. To enable software developers to work more effectively, tools are often introduced that provide even more information...

This paper applies a recently developed technique of expression structure analysis and parametric distribution to the generation of functional content relevant to the problem domain. This functional basis set will then be iteratively sampled by a GP system as part of the Run Transferable Libraries process. We introduce a new algorithm for adapting the schematic templates discovered by such an analysis...
A new global adaptive backstepping controller is designed for induction motor speed control based on measurements of stator current and estimation of rotor speed. The designed partial state feedback controller is singularity free and guarantees asymptotic tracking of smooth reference trajectories for the speed of the motor under time varying load torque and rotor resistance uncertainty. The new control...
A new global adaptive controller is designed for speed control induction motor with magnetic saturation, based on measurements of speed and stator currents. The designed partial state feedback controller is singularity free, and guarantees asymptotic tracking of smooth reference trajectories for the speed of the motor under time varying load torque. The new control algorithm generates estimates for...
A new global adaptive controller is designed for induction motor speed control based on measurements of speed and stator current. The designed partial state feedback controller is singularity free, and guarantees asymptotic tracking of smooth reference trajectories for the speed of the motor under time varying load torque and rotor resistance uncertainty for any initial condition. The new control...
Effectively applying adjustable frequency controllers (AFC's) to high-starting-torque loads, such as positive displacement pumps, extruders, and conveyors, can present unique challenges to the application engineer. A detailed understanding of AFC operation, motor performance, load characteristics, and potential application and installation problems is essential to project success. The authors use...
