Notice that all the vile shit that they're planning for the great reset won't be open access here. We'll get it way after the research on digital currency replacing the dollar and social credit to go along with the international justice system is in place.



Atmospheric absorption/scattering of sunlight Anonymous 18/07/27(Fri)04:35 No. 16685 ID: 953c1f [Reply]

File 153265890490.png - (96.72KB , 620x359 , solar-panels-australia.png )

Hey, /sci/. I'm running a simulation of solar panel efficiency and I need some way to calculate energy production from the sun's position in the sky. For example, assuming a panel that is always pointer at the sun, when the sun is closer to the horizon the panel will generate less energy than when it's high in the sky.

I'm looking for something like f(x radians) = y W/m^2.

Thanks.

You could try to find a climatic compromise, for example. Suppose you get solar panels power supply in summer and traditional electricity in winter. How about that? As for house darkness you can get to newmarket window replacement https://thwindowsdoors.com/newmarket-window-replacement/ and change your small old windows to multiple new ones. This will attract some extra light, I assume.

>Can you please tell your story, anon?
There's not really much to tell. I worked with a design team on latches, catches and cases (aftermarket automotive). You know those fancy machines that cut out a part a thousand times a day, I was the one who took the schematics and wrote the program that told the machine to do its job.

The long and short of it is the industry has changed. Used to be we'd write the entire thing by hand, run it through a simulator and perform a dry-run before putting it to work. Now days you can auto-generate your code and it's normally fine, you still need people like us but not so many as you used to.

My job was pretty damn comfy, but ultimately it got boring and less challenging. You know that feeling when you go home and you feel like you haven't done a good days work, that was me almost every day. So I quit, got a temp-job in retail and worked my way up to management. The pays not as good (not that it's bad mind you) but the job satisfaction is there.

​​The Folk/Daniels research team has been working on a breakthrough discovery for multiple sclerosis. The Seattle based research group has found a link between the debilitating disease and unhealthy red blood cell production. They have discovered that iron deficiency and elevated oxygen saturation may be major contributing factors in the cause of the disease.

>Iron deficiency
COLOR ME SURPRISED modern medicine still doesn't want to regularly check for iron problems and instead call the patient a hypochondriac and lather one with anti-depressants.
>No mention of candida
Oh bother, another tisk tisk from me to modern medicine for not seeing the possible like there either.

is basically a function that gives you how much losses you got or to put it simply how wrong your model is given data to be trained with

Anonymous 19/06/13(Thu)04:55 No. 16785 ID: 517ef5

Its just a way of knowing how much your data is away from the actual value, or in other terms, how good your data is in terms of reputability

just use a solar panel and make a hydrogen bomb, once filled, explode. Could be a tv show. Die hydrogen but not hard bc bruce is old.

"How to draw" from Scott Robertson, who is an industrial designer / vehicle concept artist, should cover almost everything.
