PhEq_bootstrap
FDA's f2 computation with bootstrap technique
This program was developed as a help in establishing pharmaceutical equivalence by use of FDA f2 coefficient. It was designed to help with f2 computation in cases when intra- and inter-batch variability is large, namely RSD>10%. The use of statistical bootstrap technique allows to implement confidence interval (CI) into the f2 coefficients resulting in overcoming of their major drawback in the original metrics. The algorithm provides possible “worst case scenario” of f2 values, thus supporting claim about pharmaceutical equivalence. The target users are researchers from industry and academia dealing with pharmaceutical equivalence problem. The software is Open Source. It was developed in Lazarus environment, therefore source code is available in ObjectPascal. -

NSLadder
Ladder editor and debugger
NSLadder is a complete PLC manager based on the Ladder diagram, it generates code that can be directly assimilated by the PLC controller (arduino, raspberry, arm cpu....) NSLadder also allows simulation without a PLC connected Ladder is one of the best visual programming languages is a PLC programming language called ladder diagram (LD) or instructions list (IL). The main strength of lader is the visual representation that is more representative than most programming languages, so people often find it much easier to learn. The clever thing about contact logic is that it is very similar to electrical relay circuits. The ladder is the graphic representation of the electrical circuit diagrams of automation. Troubleshooting automated installations is easier with the ladder language, you can quickly see what information is missing -

Nest-o-Patch
Software for analysis of patch-clamp recordings and other wave data
This program was designed mainly for preconditioning and analysis of electrophysiological data, including patch-clamp and 2-electrode voltage clamp recordings. The program includes tools both for basic analysis of whole-cell recordings or analysis of single channel properties. Program can display and analyse long traces incuding many sweeps, series and even groups simultaneously. Current amplitudes or time intervals are easily measured. Single channel conductance, kinetics, NPo, as well as number of channels in a patch and their open probability may be estimated with the analysis of dwelling time at each conductance level. The program directly reads files, created by Pulse and PatchMaster software (HEKA Elektronik Dr. Schulze GmbH) as well as ASCII files. However, the program may be useful in various applications when editing and measurements in a 2-dimentional (for example time-current) wave are required. -

Acoustic Research Tool (ART)
Acoustic Simulation Library for Frequency and Time Domain Simulations.
ART is a flexible simulation framework for wind instruments. It includes a growing library of modelling elements. So far bore discontinuities, branches, tone holes, cylindrical and conical tubes, Bessel horns and bent tubes are available for frequency domain modelling. In the time domain generic bidirectional propagation elements, scattering elements, fractional delays, convolution with reflection functions and general z-domain networks are available and can be described using MuParserX expressions. Cylindrical and conical ducts can also be defined based on their geometry. Available models and their parameters can be enumerated and combined to form simulators for complex acoustical structures. Parameters can be specified symbolically by expressions containing other parameter values or global variables. Dependencies between parameters are resolved at run time. However, MuParserX expressions are compiled at design time. Zero-delay loops are detected and reported. -

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. -

COM port notifier
System tray tool to show the available COM ports with friendly names
A tool for technicians who use USB-to-Serial converters to connect to various devices (PLCs, Frequency converters etc.). Many of the end-device supplied tools will show you all the possible COM ports on your system, and give you a headache to find which COM port belongs to your USB-to-Serial converter. This tool will help you by listing the COM ports with friendly names (as defined in the device driver). A notification with the list of COM ports will pop up at connecting a USB-to-Serial adapter. The tool can be set up to start with Windows. -

It's possible for machines to become self-aware.
This project is a quest for conscious artificial intelligence. A number of prototypes will be developed as the project progresses. This project has 2 subprojects: Object Pascal based CAI NEURAL API - https://github.com/joaopauloschuler/neural-api Python based K-CAI NEURAL API - https://github.com/joaopauloschuler/k-neural-api A video from the first prototype has been made: http://www.youtube.com/watch?v=qH-IQgYy9zg Above video shows a popperian agent collecting mining ore from 3 mining sites and bringing to the base. At the time the agent is born, it doesn't know how to walk nor it knows that it feels pleasure by mining. He has tact only (blind agent). The video shows learning, planning, executing and plan optimization. -
