LIME is a software tool for creating multiphysics simulation codes.
The Lightweight Integrating Multiphysics Environment for coupling codes (LIME) is a small software package for creating multiphysics simulation codes. LIME is intended to be especially useful when separate computer codes (which may be written in any standard computer language) already exist to solve different parts of a multiphysics problem. LIME provides the key high-level software (written in C++), a well defined approach (with example templates), and interface requirements to enable the assembly of multiple physics codes into a single coupled-physics simulation code. To achieve its flexible lightweight design objectives, LIME 1.0 requires that some amount of customized software be written each time a new multiphysics application is created. Also, modest high-level revisions or modifications to most stand-alone physics codes may be required to meet interface requirements. Detailed descriptions of these requirements together with example cases are provided in a users guide.

A highly flexible 3D flocking boids simulator, conceived as a tool for
This project concerns the design and implementation of an open-source flocking boids simulator, designed as a tool to analyze and characterize flock-like collective emerging behaviors. Each boid is conceived as an active agent and modelled by a point-mass approximation. Boid movements in a 3D space are guided by a set of elementary steering behaviors, each implemented as a force acting on the boid's point mass. Each boid is affected by interactions with both the environment and other boids. The set of considered behaviors are inspired by the well-known approach introduced in 1987 by C. W. Reynolds. The simulator delivers a 3D visual interface and provides as an output file all the instantaneous microscopic information related to each boid (positions and velocities over time), allowing in this way subsequent analysis, such as searching for synthetic and higher-level descriptions of collective behaviors, relying for instance on global network and meta-structural properties.

AFM puller control software
Nanopuller by Konrad Pawlak and Janusz Strzelecki http://dx.doi.org/10.1016/j.ultramic.2016.01.008 http://www.biofizyka.fizyka.umk.pl/ Laboratory made AFM force spectroscopy setups were present in milestone single molecule experiments and there is a growing number of groups using such equipment even though the commercial setups are nowadays widely available. The ability to tailor the setup accordingly to particular application is an advantage that makes the effort necessary for construction a worthy investment. However, one advantage of using a commercial setup – repeatability and unification, cannot be archived, as every laboratory is developing a specific data acquisition protocol and software. Our Nanopuller software (open ISC license) presented here is intended to eliminate this obstacle. We give access to a program, which with only a minimum effort can be adjusted for vast array of typical equipment.

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.

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. Features - Double-Gaussian estimator is calibrated via an axial scan of bright immobile fluorescent emitters (e.g. beads). - Template-matching and double-helix recognition algorithm is calibrated via setting an image correlation threshold against single-molecule data. - Tiff stacks of SM images are analyzed using template matching followed by double-Gaussian fitting to extract estimates of the molecule positions. - The motion/drift of fiduciaries (e.g. fluorescent beads) during an experiment can tracked and removed form SM localization data. - 3D localization data can be exported to .csv format for post-processing and visualization. - Basic 3D scatterplot and 2D z-projection histogram visualizations are included.

Discrete wavelet methods for time series analysis using python
Several python libraries implement discrete wavelet transforms. However, none of them, or at least none that I know, is aimed at scientific use. This library aims at filling this gap, in particular considering discrete wavelet transform as described by Percival and Walden. This module started as translation of the wmtsa Matlab toolbox (http://www.atmos.washington.edu/~wmtsa/), so most naming conventions and most of the code structure follows their choices. The code uses a mix of python and cython for improved performance. The code reflects my needs and preferences, but contributions from others are welcome. The code has to some extent been tested, but bugs are to be expected.
