Venn is a secure workspace for remote work that isolates and protects work from any personal use on the same computer. Work lives in a secure local enclave that is company controlled, where all data is encrypted and access is managed. Within the enclave – visually indicated by the Blue Border around these applications – business activity is walled off from anything that happens on the personal side. As a result, work and personal uses can now safely coexist on the same computer.

EventDispatcher Component
Tools that allow your application components to communicate
... subclasses, code inheritance is no longer the answer. Consider the real-world example where you want to provide a plugin system for your project. A plugin should be able to add methods, or do something before or after a method is executed, without interfering with other plugins. This is not an easy problem to solve with single inheritance, and even if multiple inheritance was possible with PHP, it comes with its own drawbacks. -

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 independent... -

RSM
Radiation Spectrum Method : a modal BPM (Beam Propagation Method)
RSM (Radiation Spectrum Method) is a 2D rigorous tool to solve the Maxwell equations for the propagation of light in integrated optics or photonics devices. It makes use of an eigenmode expansion method to solve the electromagnetic problem. This software running on Windows and MacOS comes with a GUI that permits to define with the aid of files or scripts the arbitrary and complex geometry of the waveguide. Of that way any waveguide geometry can be handled. Several plots are available... -

Simplify
Android virtual machine and deobfuscator
Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. 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... -

DarkF
DarkF is an FFT optical simulation code for GW inteferometers
... (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. -

Abaqus Implementation of Phase Field
Abaqus implementation of phase--field model for brittle fracture
A phase-field model for brittle fracture is implemented in the commercial finite element software Abaqus by means of UEL subroutine. The phase-field method considerably reduces the implementation complexity for fracture problems as it removes the need for numerical tracking of discontinuities in the displacement field that are characteristic of discrete crack methods. This is accomplished by replacing the sharp discontinuities with a scalar damage phase-field representing the diffuse crack... -

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... -

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. Add solution_method and solution_convergence to the galdef... -

A hamradio beacon project on an AVR MCU
AVR beacon project utilizes a new approach to RF signal generation using SQDDS method (making RF signals directly from the software, based on a pre-calculated periodic bit-sequence). It is mainly used by the hamradio operators to set up various radio beacons for different purposes, mostly for radio waves propagation discoveries. CW (continious waves, Morze code) is a main modulation mode. Other modes like PSK and FSK are planned to implement in the future releases. User can enter any ASCII text... -

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... -
