Datagam is a tool for extracting data from output or punch files produced by GAMESS(US) or FireFly (old name PC GAMESS) packages. Mac GUI wrapper also available. Upstream version of the project goes to the launchpad. Only final versions of the source code and compiled binars will be available from this domain.

Small-angle X-ray scattering (SAXS) in solution is a common low-resolution method which can efficiently complement high-resolution information obtained by crystallography or NMR. Sample monodispersity is key to reliable SAXS data interpretation and model building. Beamline setups with inline high-performance liquid chromatography (HPLC) are particularly useful for accurate profiling of heterogeneous samples. The program DATASW performs averaging of individual data frames from HPLC-SAXS experiment using a sliding window of a user-specified size, calculates overall parameters (I(0), Rg, Dmax and MW) and predicts the folding state (folded/unfolded) of the sample. Applications of DATASW are illustrated for several proteins with various oligomerization behaviors recorded at different beamlines.

Diamond is a confocal scanner written in python / Qt4. It combines an intuitive gui with flexible hardware abstraction classes. It is directed primarily towards quantum information processing (QIP) with single NV centers in diamond.

DIFFR is a menu-driven graphical software whereby the problem of a plane wave diffraction on a rough surface can be solved using several numerical and approximate methods.

DIMTree is Tree View Browser for DIM system. The DIM is CERN designed Distributed Information Manager system, see http://dim.web.cern.ch/. DIM uses to create distributed DAQ and experiment control systems. DIMTree is browser for DIM which provides Tree View to browse DIM Servers, his published Services and it's data content. It's useful test/monitor/debug tool for DIM users.

dmaControl is a DMA (differential mobility analyzer) control software for aerosol measurements.

dmcut2 is a scientific program designed to simulate chemical reactions at surfaces using Metropolis and Monte-Carlo methods. Short ranged interactions between adsorbates may be taken into account. Emphasis was put on code readability and usability.

This script fills in a two dimensional surface with an unbroken, non-overlapping path. The path direction is random, so one can imaging a chess board filled with dominos, with the constraint that the layout of the dominos is complete (board is filled) an

The dwi-toolbox provides a set of free and open-source Matlab routines for the simulation and analysis of Diffusion-Weighted Magnetic Resonance Imaging data. It includes data-fitting, simulation, visualization and statistical components.

A simple periodic table of elements viewer using elementary and edje.

ea-fold is a platform to perform protein folding simulations by means of evolutionary algorithms. The program implements a parallelized distributed evolutionary algorithms and a flexible force field.

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

At the moment this code can calculate free electron gas and the SIAM (single-impurity-anderson-model) In this version, the only thing computed by the code is the energy flow. There is no calculation for any thermodynamic quantaties. The implementation is very slow and rather for educational purposes to get an idea of the NRG-method. For example: it is not considered, that only matrix elements between states, whos occupation number differs by one and S_z differs by 1/2. There is only implicit parallelisation implemented by vectorizing the time consuming parts of the code.

Die Idee zu dieser speziellen Lagersoftware wurde - bedingt durch die Pandämie -und der sich einstellenden Bauteileverknappung geboren. Es handelt sich um ein reines Hochschulprojekt, KEIN privates oder kommerzielles Produkt. Die Nutzung ist nur für teilnehmende Hochschulen gedacht u nd erfordert eine Registrierung der einzelnen Institute.
