Calc Lad
Сalculator with a gold proportion calculation, memory work.
Калькулятор "Лад" является безплатной программой ("Freeware") с открытым исходным кодом и распространяется по принципу "как есть" ("as is"). Может вычислять золотую пропорцию, проценты, сохранять значения в любую из 14 ячеек памяти, и извлекать эти значения из любой из 14 ячеек памяти, В историю вычислений можно дописывать значения словами. Можно сохранять историю вычислений в текстовый файл, и подгружать сохраненный текстовый файл в калькулятор. Cправка на странице проэкта https://andreitn.narod.ru/index/kalkuljator-lad/0-5 В версии 4.6 добавлена возможность узнать результат не только после нажатия =, но и после нажатия любого из знака + - * / При этом результат вычисления автоматически записывается в историю вычислений и переносится в переменную 1 и добавляется сразу знак который вы нажали, и вам только следует указать второе число. Если вы нажали символ квадратного корня или символ золотого сечения, то второе число не нужно добавлять-результат появляется сразу. -

SPINA
Structure parameter inference approach for endocrine feedback control
SPINA is software for the rapid, reliable and accurate determination of constant structure parameters of endocrine feedback control systems. It is a class of static function tests that require nothing more than steady-state concentrations of hormones or metabolites obtained in vivo. The first version of this cybernetic approach had been developed for the evaluation of the functional status of the thyroid gland, i.e. thyroid's secretory capacity (gain of thyroid, GT or SPINA-GT) and sum activity of peripheral deiodinases (GD or SPINA-GD). A second version has been established for insulin-glucose homeostasis. It delivers the secretory capacity of pancreatic beta cells (SPINA-GBeta), an estimate for the insulin receptor amplification (SPINA-GR) and a static disposition index as a measure for the loop gain of the feedback loop (SPINA-DI). Both implementations of SPINA have been validated in more than 50 clinical studies based on large cohorts. -

Double Fractal with 3D Prototype
Easily creates high complex fractal images. Includes 3D prototypes.
Double Fractal was first created in the 90s and was the result of a passion for fractals and fractal math. Since then, it has grown including many unique fractals invented by its author. Some fractals were found by chance in 2001 when functions used for artificial intelligence were plotted as fractals. These new fractals were called JP Random Sets. The brilliant environment Lazarus allowed Double Fractal to be ported from Delphi and now Double Fractal can be run on Windows, Linux and MAC OS X. Fractals are infinite complex images defined by a finite definition. We find in fractals a model to understand many different sciences such as economy, health and weather. Many scientists love fractals. Double Fractal is a program that creates fast and easily high complex images. No specific knowledge is needed to use this program, it is a program that can be run just for fun. Please enjoy the better than ever Double Fractal 3 with its brand new 3D JP1 Set prototype. -

Transposer
Transposer changes chords from one key to another in a song file.
Transposer converts the chords of a text file which contains the lyrics and chords for a song into whatever key the user desires. Version 1.0 no new features, just some UI cleanup. No bugs reported since last BETA, so nothing to fix at this point. (0.56) was the first with a mechanism for creating an ignore list of words which might get transposed if they are on a line by themselves, such as, "ending". This word is typically made of characters which are valid chord characters that would otherwise be transposed. There are two editing panes in the main window. One is for the original song, and the other is for the transposed song. Earlier versions of this program were command line only (CLI), then I used QT to augment my C++ source to create a GUI. This project is now developed in Lazarus, using a collaborative approach. I (abudeveloper) and my son (iamslinger) are working together on this project. -
