    vHDL Obfuscator GUI

    vHDL Obfuscator GUI

    vHDL Obfuscator is an small GUI to obfuscate and reformat HDL files

    VHDL and Verilog HDL are standards languages for hardware description. Sometimes is necessary to share the source HDL file but maintaining a little level of control and protection of the intellectual property. This tool generate obfuscated code that is almost unreadable to humans, but is still readable to compilers and simulators. This tool use GHDL (https://sourceforge.net/projects/ghdl-updates/), HDLObf (https://sourceforge.net/projects/hdlobf/), Icarus Verilog (https://sourceforge.net/projects/iverilog/) and was created in Lazarus (http://www.lazarus-ide.org/)

    SPINA

    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.

    Nest-o-Patch

    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.
