| genehacker | hey do you know if they have simulated versions of real cities? | 00:11 |
|---|---|---|
| digitaltao | ? | 00:13 |
| digitaltao | like google earth in 3d mode? | 00:13 |
| -!- katsmeow [n=someone@75-120-27-229.dyn.centurytel.net] has joined #hplusroadmap | 00:16 | |
| digitaltao | its the catsmeow. | 00:16 |
| genehacker | yeah but with things like rainfall data, soil data, geography, so you can calculate water flow | 00:17 |
| * katsmeow meows | 00:18 | |
| digitaltao | hmmm | 00:18 |
| digitaltao | too what end gene? | 00:18 |
| genehacker | so you could see the effects of building a subdevelopment on an aquifer | 00:19 |
| digitaltao | hmmm | 00:20 |
| genehacker | or figure out the most optimal walmart and school placement | 00:20 |
| genehacker | like playing sim city with a real city | 00:21 |
| digitaltao | nothing comes to mind really | 00:23 |
| DrTread | optimal walmart placement: University of Oklahoma's campus. | 00:24 |
| digitaltao | heh | 00:26 |
| DrTread | on a serious note: has anyone tried to build John Alexander's STM (scanning tunneling microscope) ? | 00:27 |
| genehacker | http://modeling.water.ca.gov/hydro/model/index.html | 00:27 |
| genehacker | guess something like this | 00:27 |
| digitaltao | no, got a link to the build tread? | 00:28 |
| genehacker | I was just watching this one documentary and was reminded of sid meiers alpha centauri | 00:28 |
| digitaltao | that was a fun game. | 00:28 |
| DrTread | http://www.geocities.com/spm_stm/Project_overview.html | 00:28 |
| DrTread | i was playing with piezos today. no deflection observed with 9 VDC. But then, i'm not using this particular piezo. | 00:30 |
| DrTread | my measurement sensitivity: 0.0001" = 2.5 um | 00:31 |
| genehacker | dang | 00:34 |
| genehacker | sim city is comprehensive | 00:34 |
| genehacker | semiconductor plants don't make people move away just like in real life | 00:35 |
| genehacker | it doesn't look like sim city takes into account golf courses and their effect on water quality though | 00:36 |
| digitaltao | that is a nifty build btw Drtread. | 00:38 |
| -!- katsmeow is now known as katsmeow-afk | 00:46 | |
| DrTread | yeah, i wish i could build one myself. | 00:56 |
| DrTread | i don't know if that piezo is special | 00:56 |
| DrTread | oh, wait. i just figured it out. the "m" in "mm" isn't an "m". It's a "mu". | 00:58 |
| digitaltao | ahhhhhh | 00:58 |
| digitaltao | MOOOOOOO | 00:58 |
| DrTread | i'll need to set up an interferometer to check for movement. | 00:58 |
| -!- any34221540 [n=someone@75-120-2-14.dyn.centurytel.net] has joined #hplusroadmap | 00:59 | |
| digitaltao | yea the unimorph is the only part that looks a little tricky. | 01:00 |
| DrTread | using his number, 9 V will move the piezo 1.4 moooocrons | 01:01 |
| DrTread | so i will need maybe 30 VDC to see it with my mechanical gauge. | 01:02 |
| DrTread | maybe a problem best handled tomorrow. :) | 01:03 |
| digitaltao | yea | 01:03 |
| digitaltao | -is aboot to hit the hay | 01:03 |
| digitaltao | good talking | 01:04 |

| kanzure | According to my UPS's monitoring software, by machine idles (screen off with torrents running) at 180W and hits 210W with folding@home (GPU edition on my 8800GTS) running, 30W extra. Assuming it does that 24 hours a day (it's always on anyway as it also runs as my FTP/web server and for remote access), that comes to 21.6KW-hr per month, which at local electrical rate (9.6 cents/KW-hr) comes to $2.07 per month. | 08:29 |

| kanzure | reliability prediction software: http://www.isograph.com/workbench.htm | 09:07 |
| kanzure | "The failure rate prediction methods have the same general form, they provide you with a powerful visual interface through which you can select components, define the conditions in which they operate such as the temperature or environmental conditions. The prediction software then carries out the failure rate calculation as defined by the standard and gives you the result. The Telcordia (Bellcore) standard predicts the failure rates for mainly electronic components and is based on research on telecommunications applications. The MIL-HDBK-217 standard predicts failure rates for electronic equipment based on work carried out for the US DoD. The RDF 2000 standard predicts failure rates for electronic equipment based on the reliability data handbook published by UTE (Union Technique de l'Electricite). The NSWC handbook deals with mechanical components and is based on research carried out for the United States Navy." | 09:07 |
| genehacker | wow | 09:09 |
| kanzure | what? "The main contents of this course has: the application pulls the Laplace transformation proceeds electric circuit analysis, apply the topology and matrix the electric circuit analyzes and the analytic appearance in network changes the method of deal." | 09:09 |
| genehacker | that's amazing | 09:09 |
| kanzure | is that supposed to make any sense in this language | 09:09 |
| genehacker | yeah it means the guy that teaches the course probably isn't a native speaker | 09:10 |
| genehacker | I probably shouldn't read so many papers by russian scientists.... | 09:11 |
| kanzure | can you read russian? | 09:11 |
| genehacker | no | 09:11 |
| genehacker | just bad english | 09:12 |
| genehacker | is that software only for testing the reliability of electrical systems? | 09:13 |
| genehacker | hmmm... you can estimate wear rates | 09:15 |

| kanzure | "KVL is used to find the currents by using the voltage drop between the node and other nodes to find the current required to go through these paths to create the voltage drop. In other words, nodal analysis uses KVL to find the voltages that would create currents that would satisfy KCL." | 17:30 |
