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. -

LibreAquarium
An aquarium management software with a Simulation Model System
SME LibreAquarium is an Aquarium management system with a Simulation Model Engine (SME) that makes a prediction of the possible measurement values for the different pollutants that affect to these aquatics systems (NO3,PO4, Fe). The simulator consults the recorded analysis to calculate a prediction of the NO3, PO4, Fe, that the these aquatic system produce. It also uses a central (fish, plant and invertebrates) database to check if the actual parameters are Ok, depending on the species that live in the Aquarium. With all the records, the Simulation Model predicts the algae risk too (low,medium,high) and the algae type(green,cyanotic.) using the Redfield coefficient. Appart from that, the program tries to bring another modest contribution to Open Source Software and the World of Aquariums. SME LibreAquarium helps to daily maintenace of the aquarium with habitants control(fishes,plants, invertebrates), expenses, statistics, alarms, etc. -

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. -

Libro
An interactive program for statistical analysis of texts
A cross-platform text analysis program written in Python and Free Pascal/Lazarus which scans a whole text file (in plain text, HTML, EPUB, or ODT formats) and ranks all used words according to frequency, performing a quantitative analysis of the text using Shannon-Weaver information statistic and Zipf power law function. It counts words, sentences, chars, spaces, and syllables. Also computes readability indexes (Gunning-Fog, Coleman-Liau, Automated Readability Index (ARI), SMOG grade, Flesch–Kincaid grade level and Flesch Reading Ease).
