Differential Protection Calculator - Detect fault in a protection zone more>>
The comparison is not straightforward, however, if there is a transformer in the zone, because the magnitudes and often also the phases of the primary and secondary currents of a transformer are different. The measured value of either the primary or secondary current must be corrected, or compensated for the differences due to the transformer before the comparison.
This Differential Protection Calculator application is designed to calculate the necessary corrections. The phase difference is corrected by multiplying the measured or calculated three phase current vector by a matrix, and the magnitude is corrected by multiplying by a constant.
In addition, some other simple operations can be done with this program to the current vector, such as the change of the sign, the calculation of the complex conjugate, and the calculation of the sequence components from the phase components, and vice versa

Digital Dream Studio 2.1
DDS V2 is an image-editing software, supporting multiple layers and plug-ins. more>> Digital Dream Studio V2 is an image-editing software, allowing multiple layers and supporting plug-ins.
It has numerous methods for selection (brushes, flood-fills, spray, shapes, spline curves, color proximity and other advanced methods).
DDS V2 offers over 50 blending modes and it allows the user to create more of his own.
Among the effects that can be applied: textures, blurs, convolution, gradients, text rendering. Also, DDS has a non-linear history (similar to undo feature, but more complex), which allows overlaying the new state of a layer onto its old state, using opacity and blending settings.
Image retouch features include: SUSAN (adaptive filter for noise), Edge Enhance (adaptive sharpening filter) and JPEG Repair (removes artifacts from JPEG).
Four plug-ins are already included in the installation package: Mapping (for distorting images, using several predefined or user-defined mathematical methods), Dynamic Mapping (similar to Liquefy, but with far more options), Fractal (renders various Julia and Mandelbrot fractals) and PDE (Partial Differential Equations are simulated using the RGB channels of an image).
As a conclusion, aside from offering most of the features required in the world of image editing, Digital Dream Studio V2 includes many other new, ingenious, fine-tunable alternatives, especially designed for graphics connoisseurs.<<less

GREYCstoration 2.9
Will allow you to process a color image by locally removing small variations of pixel intensities more>> Will allow you to process a color image by locally removing small variations of pixel intensities
GREYCstoration is an image regularization algorithm that will allow you to process a color image by locally removing small variations of pixel intensities while preserving significant global image features, such as edges and corners.
The most direct application of image regularization is image denoising. By extension, it can also be used to inpaint or resize images.
GREYCstoration is based on state-of-the-art image processing methods using nonlinear multi-valued diffusion PDEs (Partial Differential Equations).
This kind of method generally outperforms basic image filtering techniques (such as convolution, median filtering, etc.), classically encountered in image painting programs.
Other comparable image denoising techniques are available (for instance, Noise Ninja, Neat Image ) but are not open-source, and the corresponding algorithms are kept secret.
On the contrary, the source code of GREYCstoration is freely available and distributed under the CeCILL License (compatible with the well-known GPL). It gives similar results (not to say better) to existing closed-source denoising filters, and is absolutely free to use.
Compared to other PDE-based regularization methods, our approach has several advantages : It performs very fast and is able to preserve thin image details since it works at a sub-pixel accuracy.
