Thanks for the details. Late night thinking about this mathematically, I came to the following conclusions: 1) bigger pond (surface area) = more efficient 2) if the pond is the same size as the lock, the weir should be 1/3 from the top (2/3 from the bottom) of the rise and returns up to 1/3 lock of water per cycle. 3) an infinitely large pond should have the weir lower, at 1/2 between top and bottom levels returning up to 1/2 a lock per cycle. This is maximum efficiency. 4) a pond between the two sizes listed above (most of them) should be somewhere between the two levels. Never lower than 1/2 way up but never higher than 2/3 of the way up. 5) the bottom of the pond should always be at the water level in the lower part of the canal. Any lower is wasteful (unless keeping it for wildlife etc). Any higher would run out sooner with consecutive uphill movements. This means the ponds are much shallower than the locks. Between 2/3 and 1/2 the rise. For a lock of rise 12ft, the pond should be between 6ft and 8ft when full. The above assume similar numbers of journeys up and down the canal.
Does the glideslope have a clearance signal? There's been a few accidents where an airliner has latched onto a sidelobe which would seem preventable if the clearance signal was present.
At 31:53 I don't understand why the peak (limaçon) corresponds to the lowest part of the modulated wave instead of the highest part of the wave (on the top left corner)? Anyways great explanation :)
Thank you… I have watched so many clips of others folding this tent and it never felt right like it was fighting itself in the bag. This method was perfect and it stayed flat and easy to put away. Again thank you so much, 🙏
Been an FAA VOR technician for 35 years and I was told 35 years ago, don't worry about your VOR it's going away soon. Here it is 2023 and still going strong. 5 more years I retire and I'm sure they will be around then. We have shut down a few and left a DME only site. Great explanation of the system. It's amazing how this technology is still going strong our engineers that were around in the 30s and 40s were very smart.
I heard they were just removing a few but it's a great system and you know the Chinese may one day take out the GPS system so not wise to remove VOR.. They did decommission thee Sioux City one near me but plenty others in the same VHF receiving distance.
I was considering buying this watch for traveling, really like it but after this video won't happen. Casio complicated this process so much that it defeats it's purpose. You're traveling to a place first need to check the city included in the watch corresponding to the place you're visiting. Are you supposed to have all included cities abbreviations and corresponding time zones in your mind? Then you can only move forward like in the second example in the video 22 times, really. From my perspective is way easier to simply set the new local time in a regular watch.
