is allowed to be increased, depending on the air speed as specified in Table 5.4.2.4, which can be as high as 2.2 degree.
So, I assume the height of the "hump" is about 2.2 degrees from the upper acceptability limit (80% or 90%).
Appreciate your advice if the understanding here is not correct.

epaired the missing xml closing statements, but a lot of data is missing from this file. Ddi you make it yourself or did you download it?

e same time consider gravity (gravity on) at the crosssectionoptimization?
And the reduction of the allowable stress to "some" value means what exactly? 80% or more? and is it a discrete or continuous reduction?
Excuse my curiosity and thanks for your help.much appreciated.…
bjectives. I've write my master thesis about the environmental multicriteria optimizations, and usually, you can define the objective according to environmental criterias (concerning the daylight for instance, in the environmental certifications, they say you have to obtain at least 2% of light factor in 80% of the room).Tell me if you find something interesting using wind datas ;)…
y to control the minimum and maximum width of my louvers? For example near the attractor points 40 cm and far away from the attractor points about 80 cm.
…
ose space to make the louver look dense at some part.
Here' my method toward those space creating.
First, i create a numeric combination, so i got 3,9,15,30.
Second, i repeated the data until the length i want, and jitter them. Here's what i get:
30,3,9,3,15,9,30,30,15,3,3,15,30,9,3,3,15,3,3,9,9,3,15
Actually what i`m trying to achieve shown below:
3,9,3,3,30,3,15,9,15,30,30,15,30,3,9,15,9,3,3,15,3,9,3
My idea is, to make the center part look no so dense compare to others part, somehow
it's no a absolute looking in the final. What i mean is, maybe more [30] like 80% drop at the center part, 80% of [3] drop at the start and the end, meanwhile the others 20% [3] and [30] appear to be random in whole series.
Last, i will weave this set with other set which stand of the dimensions of sticks.…
exact formula is inside /lib/skybright.cal if this can help you to find the name.
{ RCSid: $Id$ } { Sky brightness function for sunny and cloudy skies.
Additional arguments required for calculation of skybright:
A1 - 1 for CIE clear, 2 for CIE overcast, 3 for uniform, 4 for CIE intermediate A2 - zenith brightness A3 - ground plane brightness A4 - normalization factor based on sun direction A5,A6,A7 - sun direction }
cosgamma = Dx*A5 + Dy*A6 + Dz*A7;
gamma = Acos(cosgamma); { angle from sun to this point in sky }
zt = Acos(A7); { angle from zenith to sun }
eta = Acos(Dz); { angle from zenith to this point in sky }
wmean(a, x, b, y) : (a*x + b*y) / (a + b);
skybr = wmean((Dz+1.01)^10, select(A1, sunnysky, cloudysky, unifsky, intersky), (Dz+1.01)^-10, A3);
sunnysky = A2 * (.91 + 10*exp(-3*gamma) + .45*cosgamma*cosgamma) * if( Dz - .01, 1.0 - exp(-.32/Dz), 1.0) / A4;
cloudysky = A2 * (1 + 2*Dz)/3;
unifsky = A2;
intersky = A2 * ( (1.35*sin(5.631-3.59*eta)+3.12)*sin(4.396-2.6*zt) + 6.37 - eta ) / 2.326 * exp(gamma*-.563*((2.629-eta)*(1.562-zt)+.812)) / A4;
