PocketSVG
Easily convert your SVG files into CGPaths, CAShapeLayers, etc.
A simple toolkit for displaying and manipulating SVGs on iOS and macOS in a performant manner. The goal of this project is not to be a fully compliant SVG parser/renderer. But rather to use SVG as a format for serializing CG/UIPaths, meaning it only supports SVG features that can be represented by CG/UIPaths. Thoroughly documented. -

Moveable
Draggable, resizable, scalable, rotatable, warpable application
Moveable is draggable, resizable, scalable, rotatable, warpable, pinchable, groupable, and snappable. Draggable refers to the ability to drag and move targets. Resizable indicates whether the target's width and height can be increased or decreased. Scalable indicates whether the target's x and y can be scale of transform. Rotatable indicates whether the target can be rotated. Warpable indicates whether the target can be warped (distorted, bented). Pinchable indicates whether the target can... -

sidmon5.net
Sudden ionospheric disturbance monitor with Stokes data product
This package is a VLF receiver for monitoring VLF transmitter signals for evidence of transients indicating ionospheric disturbances, usually caused by x-ray bursts from the sun. It takes sample pairs from dual-channel sound cards and spectrally processes them to Stokes parameters. Data are plotted as time series and in scatter plots. -

RoughSwift
Create hand-drawn, sketchy, comic shape in Swift
Create hand-drawn, sketchy, comic shape in Swift. RoughSwift allows us to easily make shapes in a hand-drawn, sketchy, comic style in SwiftUI. Use the generator in draw function to specify which shape to render. The returned CALayer contains the rendered result in the correct size and is updated every time the generator is instructed. The beauty of CALayer is that we can further animate, transform (translate, scale, rotate) and compose them into more powerful shapes. -

EllipseFitting
Pre-processor for ellipse data to improve ellipse fitting.
Ellipse fitting is a highly researched and mature topic. Surprisingly, however, no existing method has thus far considered the data point eccentricity in its ellipse fitting procedure. Here, we introduce the concept of eccentricity of a data point, in analogy with the idea of ellipse eccentricity. We then show empirically that, irrespective of ellipse fitting method used, the root mean square error (RMSE) of a fit increases with the eccentricity of the data point set. The main contribution... -

Stress intensity factor (SIF) calculation from crack tip displacements
The code implements Muskhelishvili's complex function approach to calculate 2D stress intensity factors (modes I+II) from crack tip displacement fields. Surface displacements can be used with a plane stress elastic model. The code uses power/Fourier series expansion and a conformal mapping of an ellipse onto a circle. -

Constrained Ellipse Fitting
MATLAB Code for Constrained Ellipse Fitting with Center on a Line
The provided Matlab code allows for fitting an ellipse to given data points with the additional prior knowledge that the center of the ellipse is located on a given line. The usage of this constraint in a new global convergent one-dimensional search problem ("Tunneling") improves the fitting accuracy compared to other ellipse fitting methods. You can find more details on the theoretical background of the presented algorithm here: http://doi.org/10.1007/s10851-015-0584-x If you use the code... -
