Mmaintenance of wind turbine farms is a huge task, with associated significant risks and potential hazard to the safety wellbeing people who are responsible for carrying tower inspection tasks. Periodic inspections required ensure that turbines in full working order, no signs failure. Therefore, development an automated system has been very crucial overall performance renewable power generation...

In this study, we employed a four-hole cobra probe to measure the wake characteristics of rec-tangular bridge tower model in wind tunnel. The scale was 1:30, and Reynolds number varied from 1.38 × 105 2.27 by changing yaw angle. A measurement plane with 9 19 points horizontally set at middle height behind model. test without control, i.e., baseline case, first tested angle range 0° 90°; then, f...

Some of the algorithms for solving the Tower of Hanoi puzzle can be applied “with eyes closed” or “without memory”. Here we survey the solution for the classical tower of Hanoi that uses finite automata, as well as some variations on the original puzzle. In passing, we obtain a new result on morphisms generating the classical and the lazy tower of Hanoi, and a new result on auomatic sequences.

The fog entered and escaped through the openings of the tower, displaying iridescent colors and creating ever-changing and fast-moving fog shadows of the tower and the cables (Figure 2). I emailed a few images to Dr Andrew T. Young at the Astronomy Department, San Diego State Univ...
