How to display a RGB image (MFISH)?
by jp April 3, 2023

April 3, 2023

Hi, I have written a script to try to combine five images into a three channels RGB images<http://dip4fish.blogspot.com/2011/05/trying-to-combine-mfish-images-into-rg…> . The resulting RGB image looks like a grey scale image instead of a color one. I have three np.array Rnorm, Gnorm, Bnorm which are copied into a rgb array: *rgb = np.zeros((shape[0],shape[1],3),dtype=float) mxr=np.max(R) mxg=np.max(G) mxb=np.max(B) Rnorm=np.uint8((255*(R/mxr)))Gnorm=np.uint8((255*(R/mxg)))Bnorm=np.uint8((255*(R/mxb)))#copy each RGB component in an RGB array rgb[:,:,0]=Rnorm rgb[:,:,1]=Gnorm rgb[:,:,2]=Bnorm* *pylab.subplot(224, aspect='equal',frameon=False, xticks=[], yticks=[]) pylab.imshow(rgb) pylab.show()* Any advice? Thank you Jean-Patrick

Help required regding Eigenvectors
by Sudheer Phani March 14, 2022

March 14, 2022

Hello All, I have been encountering some strange problems with the calculation of eigen vectors using python. The problem is with the sign of the eigen vectors calculated. On Very few occasions the eigen vectors calculated using python have an opposite sign than the actual eigenvectors, though the magnitude is correct. Can any one of you plz help me in this regard and suggest me some solution if you have encoutered similar problems . Any help in this regd is appreciated Thanks in Advace regds Sudheer

Fwd: PhD position in the Netherlands; solar energy/Python

Hello, sharing a PhD position opening at Utrecht in Netherlands. Read more below... ---------- Forwarded message --------- From: Mark Mikofski <bwanamarko(a)gmail.com> Date: Fri, Apr 30, 2021, 12:29 PM Subject: Fwd: PhD position in the Netherlands; solar energy/Python To: Mark Alexander Mikofski <mikofski(a)berkeley.edu> PhD positions with Wilfried van Sark at Utrecht Netherlands ---------- Forwarded message --------- From: abedw...(a)googlemail.com <abedwayyad(a)googlemail.com> Date: Monday, April 19, 2021 at 9:22:00 AM UTC-7 Subject: PhD position in the Netherlands; solar energy/Python To: pvlib-python <pvlib-python(a)googlegroups.com> Hello all, I did my MSc with Wilfried at Utrecht (the Netherlands). He's a truly wonderful mentor with an amazing and broad grasp of the knowledge. 10/10 would recommend doing a PhD there if you or someone you know would like to develop solar forecasting models. They are looking for pythonistas. All the best, Abed ---------- Forwarded message --------- From: dr. Wilfried van Sark - W.G.J.H....(a)uu.nl <blackboar...(a)uu.nl> Date: Wed, Apr 14, 2021 at 4:11 AM Subject: Master Energy Science: Looking for PhD/junior researchers To: Dear all, I am looking for talented and motivated junior researchers that would be interested to work in two projects: 1) ROBUST project: this recently granted project is focused on investigating options for flexibility in local electricity grids by using vehicle-to-grid technology in neighborhoods in Utrecht and Arnhem. We require experience with data analysis and simulation using Python. In this project we collaborate with WeDriveSolar and TUDelft. We have funding for at least 44 months available. 2) PVObs and SolFaSi projects. Both projects deal with photovoltaic performance and forecasting. The PVObs project aims to create a large database of PV systems in the Netherlands in order to assess their performance and from that determine with better accuracy the contribution of PV to the national electricity demand. Parnters in this project are CBS and SunData. The SolFaSi project aims to develop PV forecasting at high time and spatial resolutions using all-sky imagers (aka cloud cameras). We will install three cameras at the UU campus and one at KNMI. This network allows to construct a moving shadow field over the campus. This should be correlated with the power generation of the 4000+ PV panels at campus buildings. We require experience with (big) data analysis and simulation using Python. We have funding for 24 months available. If you are interested, or if you know someone who may be interested, please send me a mail at w.g.j.h....(a)uu.nl best regards Wilfried
