ied images (in the form of a time series). At first, the idea was to take time series of satellite imagery and label them accordingly into urban and non-urban. Since this step alone seemed too time consuming for now, we took a different approach. We photographically documented the growth of the slime mold Physarum Polycephalum in a Petri dish (about 2000 images in 2-min increments) and then labeled them into fungal and non-fungal.
We would now like to use this labeled data (in the form of a list of black levels for each pixel) to make a prediction using Crow. Our first consideration is to use as input the pixel values of time step n and as output those of time step n+X and to train the network in this way (X could be 1, i.e. 2 min in the future, or 10, i.e. 20 min in the future). We would then use a later time step as a test, which is not included in the training set. So we could then compare the real output with the generated one.
Now the questions:
How realistic is it to perform such a prediction using the backpropagation approach in Crow? Especially also with regard to the structure of input and output (both times long lists of pixel values)? Will this detect the patterns of the temporal component, even if they are not explicitly stored in the inputs and outputs?
Or in general, is it realistic to do this kind of time prediction with Crow?Thank you to anyone in advance who might be able to help!…
si à faire le tri avec Grasshopper et l'outil Points in Brep, comme je pensais. Je suis passé d'environ 400 000 points à uniquement 20 000 points autour de mes 3 rails. C'est très efficace (mais un peu dangereux avec tous ces points).
J'ai interdit au composant CircleFit de faire un cercle, s'il n'y a pas au moins 5 points présents sur la section. Car lorsqu'il y a seulement 3 ou 4 points, il suffit qu'il y en ait un pour que le cercle soit faux, alors qu'au delà, le cercle a plus de chance d'être "bon".
J'ai également créé des "Pipe" (créés à partir de portions de l'axe) au lieu des "Box » de sélection des points pour éviter de sélection trop de points que ne serait pas des points du rail.
J'ai ensuite créé des « panel » pour la moyenne des distances en X et en Y et la moyenne des distances centre à centre.
Tout cela fonctionne bien avec un axe et un tuyau. Mais maintenant j'essaie d'appliquer ça à plusieurs rails en même temps. Je crois avoir compris qu'il faut créer des « path » dans l'imput manager, et faire correspondre le « path » de l'axe et celui du Tuyau.
Dans mon exemple j’ai mis 3 courbes et 21 sections. Au moment où j'utilise les boîtes pour créer les portions des axes, il crée 63 « sous-path » de 1 courbe alors qu'il faudrait qu'il crée 3 "paths" de 21 courbes, enfin si j'ai bien compris.
Car une fois qu’il a créé les points à l’intérieur des « Pipe », il doit les projeter sur les plans correspondant. Et c’est là que le problème se voit. Il ne fait pas correspondre les points à projeter et les plans.
Je vous envoie la version à une courbe et un tuyau (c’est la v5 avec un fichier rhino ou la courbe d'axe est "bakée" pour pouvoir faire un zoom sur la zone plus rapidement) et je vous envoie également, celle avec 3 courbes et 3 tuyaux. Sachant qu’il faudra également attribuer un rayon pour un des tuyaux et un autre rayon pour les deux autres.
Tout ça est bien compliqué, j’espère que je ne vous embête pas trop.
Merci d’avance.…
you have a list that looks like this...
0. mesh_FromPoints
1. 7.0
2. 11.0
The SQL Format Rows will simply format the list items into a single string separated by commas: "mesh_FromPoints, 7.0, 11.0"
If you want to have multiple rows in a similar format, you will want to input a data tree that looks like...
{0}
0. mesh_FromPoints1
1. 7.0
2. 11.0
{1}
0. mesh_FromPoints2
1. 5.0
2. 20.0
{2}
0. mesh_FromPoints3
1. 20.0
2. 8.0
In which case the SQL Format Rows will give you a list of strings...
0. "mesh_FromPoints, 7.0, 11.0"
1. "mesh_FromPoints, 5.0, 20.0"
2. "mesh_FromPoints, 20.0, 8.0"
Hope this helps...

Horticulture and Landscape in same time.
The most common plastic materials used as agricultural films are the low density polyethylene (LDPE, with a density less than 0.93 kg m−3), the copolymer of ethylene and vinyl-acetate (EVA)
Also here you can find the characteristics of the flexible materials for greenhouse covers (adapted from CPA, 1992 and Tesi, 2001) as much as i get.
UV-PE Film ( UV-PE~ polyethylene Long life or UV)
Thickness (mm) = 0.18
Direct PAR transmissivity (%) = 90
Diffuse PAR transmissivity (%)= 86
Long-wave IR transmissivity (%)= 65
EVA Film ( EVA~Ethylene vinyl-acetate copolymer)
Thickness (mm) = 0.18
Direct PAR transmissivity (%) = 90
Diffuse PAR transmissivity (%)= 76
Long-wave IR transmissivity (%)= 27
and here you will find the global heat transfer coefficient’ (K in W m−2 °C−1) for the above greenhouse covering materials, measured under normalized conditions (temperatures: exterior: −10°C, interior: +20°C, wind: 4 m s−1). (Source: Nisen and Deltour, 1986.)
Cover Clear sky Overcast Sky
Single PE 8.8-9.0 7.1- 7.2
Single EVA 7.8 6.6
Note : the PAR radiation (photosynthetically active or photoactive radiation and its the amounts to 45–50% of the global radiation; Berninger, 1989)
The name PAR is used to designate the radiation with wavelengths useful for plant photosynthesis. It is accepted that the PAR radiation ranges from 400 to 700 nm (McCree, 1972), although some authors consider the PAR from 350 to 850 nm.
The composition of the radiation changes with time, as a function of the Sun’s elevation and the cloudiness. When the Sun is low over the horizon, the short wavelengths are reduced (less UV and more red). The clouds reduce the amount of energy, greatly decreasing the NIR.
The PAR proportion in relation to the global radiation increases with scattering (diffusion). It is lower with clear sky and in the summer (45–48%).

izes. I've been doing this up until now using a very rudimentary VB script I wrote that looks like this:
If x < .8875 Then A = .75 ElseIf x >= .8875 And x < 1.025 Then A = .8875 ElseIf x >= 1.025 And x < 1.1625 Then A = 1.025
.......and so on and so on
You can see how clumsy this is. What I would like to do is take this script and make it dynamic; so I can plug in a step size and let it run through a loop of some kind so if I decide we want 20 unique sizes instead of 10, I don't have to go in and re-work all that cumbersome code. I've tried this with For loops and Do While loops...but I must be missing something cause it isn't working. Currently my loop looks like this: (n is number of steps/unique members, min is minimum size, and steps is the increment of length from n to n+1)
For i = 0 To i = n - 1 If l >= min + steps * i And l < min + steps * (i + 1) Then A = min + steps * i - .05 Else i = i + 1 End If Next
The code works, but doesn't loop. Can anybody point me in the right direction to fix this?…

CONSTRUCTING FOR UNCERTAINTY
Design and construction, increasingly more information-centric, must also address issues of computational ambiguity. As users, we must drive computational systems to assume new roles and subsume more domains to meet the needs before us. We must consider issues of time and permanence within a cultural and technological landscape of constant change - our most grand gestures will define our environment physically, culturally and economically for generations.
Where historic responses to uncertainty constructed a simplistic environment with basic mechanisms for aggregation and subdivision, we augment these with smart, dynamic and interactive systems. Where modeling capacity has been limited, we now take advantage of vast amounts of data collected by sensing and scanning devices, processed by cluster or grid computing, filtered by machine learning algorithms into patterns, and communicated by ubiquitous devices. Our past data trajectories can guide us in discovering robust and tolerant design systems to meet the demands of a malleable present and uncertain future.
sg2013 Constructing for Uncertainty: transition computational design from the hard space of the ideal to the soft reality of an uncertain built environment.

he "source_" = 0 (SRTMGL1) is limited to 60 degrees North. The bug is fixed. Check the attached file.
Thank you for posting the link to ArcticDEM! I was not aware of it, it certainly looks very intersting!The 2 meter resolution also sounds wonderful!
Gismo at the moment only generates terrain and underwater terrain from three upper mentioned sources: SRTMGL1, AW3D30, GMRT.
https://www2.jpl.nasa.gov/srtmhttps://www.eorc.jaxa.jp/ALOS/en/aw3d30https://www.gmrt.org/services
The reson for this is because all thre of them are supported throug opentopography.org's query terrain web service, which enables to get the DEM data only for defined boundaries (in Gismo's case the _location and the radius_ inputs). This means that the terrain model is automatically generated by just defining these two inputs.The same principle is followed for openstreetmap shapes - automatic generation for given two inputs.
Geting DEM from services as ArcticDEM, would require finding the appropriate DEM tile containing the desired _location, downloading it manually and then loading it to Gismo.Even though this is possible and "under the hood" Gismo and MapWinGIS have methods capable of performing such task, I am still reluctant to do it. My assumption is that it may create a number of questions about reprojections, and non-alignment caused by the use of different coordinate reference systems.But if this feature is asked from a certain number of users, I assume that in the end I would have to provide it.
Let me know if the upper used "source_" = 1 (resolution 20 to 30 meters) fulfils your current terrain requirements.…
