Quantum Wells, Wires and Dots
A set of tools for simulating semiconductor nanostructures.
This software accompanies the textbook "Quantum Wells, Wires and Dots" (4th Edition), Paul Harrison and Alex Valavanis, Wiley, Chichester (2015). It is adapted (by the same authors) from code that was originally supplied on a CD with the first edition of the book [1] and is now made available under the GPL3 license. In brief, we encourage everyone to use the software in your studies and research, to study and modify the source-code and to share it widely. However, you are not permitted to include any of our code in a closed-source project. -

SphereSim
Physical simulation of particle movements
Physical simulation of particle movements. The computer program SphereSim simulates and animates the behavior and the movement of particles in a space. By forces (such as gravity in a particular direction and between the particles, repulsion of the particles against each other and from the walls, Lennard-Jones-Potential between particles) different physical effects in particle groups are calculated and shown, such as the Brownian motion. The application uses the programming language C++ and the Qt, OpenGL and OpenMP libraries. -

Veritas RIXS Analysis
Advanced data analysis for Veritas beamline at MAX IV
You can do advanced analysis using the raw data from RIXS .h5 file. It has several tabs using which you can do different types of analysis, thereby utilizing the full potential of the Veritas beamline. Some of the features in addition to standard RIXS data analysis are: - continuous and discrete RIXS maps, - RIXS spectromicroscopy, - radiation damage analysis, - Q calibrations. -

Virtual Reflectometer
Simulates basic reflectometer scans with X ray tracing.
With Virtual Reflectometer (VR), you can simulate the basic alignment scans of a basic X ray reflectometer (diffractometer) with a Goebel mirror using ray tracing. With this program, you can characterize reflectometers and get a reflectometer-dependent overillumination correction for X Ray Reflectivity (XRR) scans. The pogram serves as an educational tool for explaining alignment and for a proper overillumination correction of XRR data. !!Paper will be referenced!!. VR can be run by code in Matlab or as a standalone app. It's not necessary to have Matlab installed on your computer if you want to use the standalone app (Download button). You can find a documentation in the wiki tab. The program is freshly released. So feedback is very welcome in order to improve it. You can write a discussion entry in the wiki tab or write me a mail to elias.hils@uni.kn -

XMDS
Fast integrator of stochastic partial differential equations
XMDS is a code generator that integrates equations. You write them down in human readable form in a XML file, and it goes away and writes and compiles a C++ program that integrates those equations as fast as it can possibly be done in your architecture. -

YCTget
Program to fetch datas from YC-7x7 dataloggers from YCT
We needed a datalogger, we found one. But the supplied VB6 program was very crappy, _really_ unusable, even on old XP machines. So I did mine, able to run under windows and linux. All the fun was to reverse the (binary) RS232 protocol. Our is a YC-727D with 2 thermocouple inputs, but the protocol is the same for 1, 2, 3 or 4 inputs models (YC-717, YC-727, YC-737, YC-747). Bytes orders needs to be checked for 3th and 4nd channels tough. -

easy-dhpsf
GUI for fitting 3D single-molecule images using the double-helix PSF
This package of MATLAB routines with accompanying GUI allows scientific users to measure the 3D location of single molecules when using the double-helix point spread function (DH-PSF) widefield microscope. Version 2 also includes code that facilitates combining localization data from two spectral channels using a locally-weighted quadratic 3D registration function Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads) - DH localization is performed through template matching and subsequent double Gaussian fitting - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions - Two spectral channels are registered by generating a locally-weighted quadratic mapping function from control point pairs -

This package includes a collection of MATLAB files which are designed to: 1. Given a calibration scan of the image of a point emitter with an engineered point spread function (PSF), 2. Perform a phase retrieval algorithm based on maximum likelihood estimation (MLE) of a phase aberration term which is added to the theoretical pupil function of the imaging system. 3. Use the phase-retrieved pupil function to perform single-emitter localization. Accompanying publication available here: https://doi.org/10.1364/OE.25.007945
