XD1DD
XD1DD: X-ray Diffraction for 1 Dimensional Disorder
The computer program is designed to calculate powder X-ray diffraction patterns for one-dimensionally (1D) disordered crystals, i.e. containing planar defects. Calculations are made on the basis of statistical models, where the Markov chain with stationary transition probabilities is used as a probabilistic rule for generating a 1D disordered sequence of layers. The model takes into account the short-range order in the alternation and methods of layer superposition, which allows simulating various cases of distribution of planar defects in crystals. ... -

MarkerMapper
A cost-effective localization system using planar squared markers
This project allows the creation of cost-effective camera localization systems based on squared planar markers you can print at home. Print the markers, place them in the environment and record a video or take pictures of them. This project analyzes the images and returns the 3D location of the markers: the marker map. The map generated can be used by ArUCO library for localizing your camera. The library depends on Aruco for the marker detection: https://www.uco.es/investiga/grupos/ava/portfolio/aruco/ It also depends on OpenCv and eigen3 (the later is included in the 3rdparty directory). -

OpenJUMP is a community driven fork of JUMP the "Java Unified Mapping Platform" GIS software. The original JUMP was developed by Vivid Solutions, released under GPL2 in 2003 and discontinued in 2006. During 2004 already some enthusiastic developers joined together to enhance further the features of JUMP. They launched an independent development branch called OpenJUMP. The name gives credit to the original JUMP development, and at the same time describes the objectives of this project to...

GrainSizeTools script
A Python script for estimating the grain size from thin sections
Homepage & docs: http://marcoalopez.github.io/GrainSizeTools/ GrainSizeTools is a free, open-source, cross-platform script written in Python that provides several tools for (1) estimating average grain size in polycrystalline materials, (2) characterizing the nature of the distribution of grain sizes (either from apparent distributions or approximating 3D grain size distributions via stereology), and estimating differential stress via paleopizometers. The script requires as the input the areas of the grain profiles measured grain-by-grain on planar sections and does not require previous experience with Python programming language (see documentation below and FAQ). For users with coding skills, the script is organized in a modular way facilitating the reuse and code extension. Lopez-Sanchez, MA (2018). GrainSizeTools: a Python script for grain size analysis and paleopiezometry based on grain size. ... -

Alpha Dose Rate Calculator (ADRC)
Alpha radiation code for dosimetry calculations by Angus Siberry
ADRC is a geometrical alpha radiation code designed to calculate doses from radionuclide-containing solids exposed by surrounding media. The current version is only applicable to UO2 in water (radiolysis rates are also calculated in the results). More radionuclide containing materials and surrounding media options coming soon. **Note: All previous versions before v2 have an outdated script and any results used from simulations should be updated, reasons for this are explained in the... -

Objectron
A dataset of short, object-centric video clips
The Objectron dataset is a collection of short, object-centric video clips, which are accompanied by AR session metadata that includes camera poses, sparse point-clouds and characterization of the planar surfaces in the surrounding environment. In each video, the camera moves around the object, capturing it from different angles. The data also contain manually annotated 3D bounding boxes for each object, which describe the object’s position, orientation, and dimensions. The dataset consists of 15K annotated video clips supplemented with over 4M annotated images in the following categories: bikes, books, bottles, cameras, cereal boxes, chairs, cups, laptops, and shoes. ... -

Invariant curve calculations in Matlab
Calculating stable & unstable curves for 2 dimensional maps in matlab.
This is an implementation that follows closely the algorithm for calculating stable curves, described by J. P. England, B. Krauskopf, H. M. Osinga in the paper "Computing One-Dimensional Stable Manifolds and Stable Sets of Planar Maps without the Inverse" published in SIAM J. APPLIED DYNAMICAL SYSTEMS 3.2 (2004), 161-190. The package also contains an implementation for calculating the unstable curves which is based on the paper "Growing 1D and Quasi-2D Unstable Manifolds of Maps" by Bernd Krauskopf and Hinke Osinga published in Journal of Computational Physics (Oct 1998), Volume 146, 404-419. ... -

AmberAnalysis
Command-line tools for analyzing Amber Molecular Dynamics simulations.
A suite of command-line tools for analyzing chemically relevant features of an Amber Molecular Dynamics simulation. Can detect the position of a planar interface between two substances and plot density relative to that interface for atoms of an arbitrary type, name, charge, or residue. Orientation of three-atom residues (such as water) may be calculated and plotted. Uses parallel processing to detect hydrogen bonds, and can produce a bonding profile. Output files can be displayed as graphs using the included matplotlib python graphing script. -

ArchNURBS
NURBS-based elastic and limit analysis of masonry arches in MATLAB
ArchNURBS is a MATLAB tool for the analysis of planar curved structures, with a particular attention to masonry arches. As in CAD softwares, the geometry of the model is defined by a NURBS representation of the structure. Indeed, the user can upload geometries imported from a CAD environment. Based on such a representation, ArchNURBS performs the elastic isogeometric finite element analysis and the collapse limit analysis of the structure. -

LipidWrapper
Create lipid-bilayer models of arbitrary geometry.
LATEST VERSION NOW LOCATED AT http://git.durrantlab.com/jdurrant/lipidwrapper As ever larger and more complex biological systems are modeled in silico, approximating physiological lipid bilayers with simple planar models becomes increasingly unrealistic. When building large-scale models of whole subcellular environments, models of lipid membranes with carefully considered, biologically relevant curvature are essential. LipidWrapper, written by Jacob Durrant in the lab of Rommie E. Amaro, is capable of creating curved membrane models with geometries derived from various possible sources, both experimental and theoretical. ... -
