EventDispatcher Component
Tools that allow your application components to communicate
The EventDispatcher component provides tools that allow your application components to communicate with each other by dispatching events and listening to them. Object-oriented code has gone a long way to ensuring code extensibility. By creating classes that have well-defined responsibilities, your code becomes more flexible and a developer can extend them with subclasses to modify their behaviors. But if they want to share the changes with other developers who have also made their own... -

libthreadar
C++ library to manage threads and any type of exception between them
Libthreadar is a C++ library providing an abstracted set of C++ *classes* to manipulate threads in a very simple and efficient way from your C++ code. It also handles exceptions thrown from a thread and propagated to another one, when the later is calling the thread::join() method. This let one manage exceptions as simply as it is in C++ single threaded context. Additionally, all the related objects around multi-threading (mutex, semaphore, ...) are provided, under easy to use and... -

DarkF
DarkF is an FFT optical simulation code for GW inteferometers
...Beams and mirrors are sampled on a grid of coordinates (x; y) and the DarkF resolution is depending on the grid size and on the sampling rate (typically a size of 0.6m (larger than a mirror) and a sampling rate of 256*256). With the Fourier transform method, it is easy to obtain a propagated beam and we can use this code to simulate a simple or a complex system as a Fabry Perot cavity or Advanced detector, like Advanced Virgo, Advanced LIGO or Kagra. It can include reflection and transmission maps from measurements or real mirrors. -

Simplify
Android virtual machine and deobfuscator
...Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. ... -

Abaqus Implementation of Phase Field
Abaqus implementation of phase--field model for brittle fracture
...The nonlinear coupled system consisting of the linear momentum equation and a diffusion-type equation governing the phase-field evolution is solved simultaneously via a Newton–Raphson approach. The implemented crack propagation model does not require predefined paths for crack growth or user-defined surfaces to simulate crack debonding. http://dx.doi.org/10.1016/j.commatsci.2014.05.071 -

glSatellite Demo
Technological demo of OpenGL ES 2 Android NDK
Technological demo of OpenGL ES 2 for Android platform. It reads public NORAD satellite database and shows the satellite positions and altitude related to Earth in the form of beams (the height of the beam represents the relative altitude). NOTE: The project has been moved to GitHub: https://github.com/nuald/glSatellite-Demo The old one stays here just for the historical reasons. The 3D features present: - OpenGL ES 2; - rotating, multi-touch zooming and moving the globe; - stars on a fixed background; - each satellite is represented by a beam with a unique color; - identifying the corresponding satellite if a beam has been tapped (based on color picking method). ... -

RigMechanix
Super quick load analysis for rigged structures. No more Span Tables!
RigMechanix is an tool for analytically assessing the safety and loading of basic rigged structures, typically for use in the performing arts industries. The idea is to replace safety reliance on commonly-used "span tables" with a faster and more accurate method. RigMechanix will not only output accurate loading values indicating any that are unsafe, but also warn the user of excessive local deformation due to excessive point loads, span lengths that are too large, as well as areas of weakness. It is designed to be used on-the-fly as much as it is in the preparation stage; there is a strong emphasis on speed & RigMechanix will contain an expandable database of fixtures, truss/beam types & rigging points ready for use so that input models can be created, edited and analysed in as little time as possible. ... -

galprop_propel
GALPROP update for accurate propagation calculation
The GALPROP program (http://galprop.stanford.edu) computes cosmic-ray propagation numerically. To obtain manifestly accurate solutions an explicit method is now available to replace the Crank-Nicolson operator-splitting method. This can be implemented in the public version of GALPROP with the update provided here. Instructions: replace the four files propel.cc, propel_diagnostics, Galdef.cc and Galdef.h and rebuild the executable. -

EGA
A novel and effictive GA algorithm to solve optimization problem
Classical genetic algorithm suffers heavy pressure of fitness evaluation for time-consuming optimization problems. To address this problem, we present an efficient genetic algorithm by the combination with clustering methods. The high efficiency of the proposed method results from the fitness estimation and the schema discovery of partial individuals in current population and. Specifically, the clustering method used in this paper is affinity propagation. The numerical experiments demonstrate that the proposed method performs promisingly for well-known benchmark problems in the term of optimization accuracy. -
