LIDAR systems are able to provide preview information of wind speed, direction and shears at various distances in front of the wind turbines. This technology paves the way for new control concepts such as feedforward control and model predictive control to increase the energy production and to reduce loads of wind turbines. This paper describes how the necessary information can be obtained from...

Abstract During the solidification of binary metal alloys, chemical heterogeneities at product scale over a long distance range (1cm-1m) develop and this has detrimental effect on the resulting mechanical properties of cast products. Macrosegregation is of great concern to alloy manufacturers and end users as this problem persist. In this study, the use of process parameters namely casting spee...

The measuring system of a marathon runner by using the realtime image processor Picot (PICture COmpuTer) and fast graphic processor HSP has been newly developed. It includes two subsystems, pitch (step frequency) detection and CG display of a runner. Pitch detection subsystem detects the runner's pitch by image processing. CG display subsystem detects the position of the joints of the runner's ...

A 20-year-old female running the Marine Corps Marathon developed diarrhea at mile 12. After finishing the race she noted that she was covered in bloody stool. A local emergency department suspected ischemic colitis. After discharge, her primary care physician instructed her to discontinue the use of all nonsteroidal anti-inflammatory drugs. Her symptoms resolved and she returned to running with...
