Lernstick Exam Environment is a live Linux distribution with a focus on exam situations, usually installed on USB sticks. To provide up-to-date software choice on a solid base, it uses a combination of Debian stable with official and custom backports. Access to local storage media (internal hard drive, other USB storage media) or network access is prohibited per default, but certain network connections (e.g., to network printers or websites) can be allowed in a whitelist.
The EESST package implements a common format for Email Exchange of Secondary School Transcripts. MIME and OpenPGP email standards are applied to enable secure communication of academic transcripts directly from each student to his or her chosen recipients without intervention or monitoring by any third-parties. Because transcripts are digitally signed by the originating school official, transcript recipients can independently verify that transcripts received directly from students have not been altered in transit.
FísicaLab is an educational application to solve physics problems. The problems are set up by adding elements from the palette to a chalkboard and entering the data for each element. The elements are objects such as blocks, pulleys, motors, and forces. It can use the SI and English unit systems, scientific notation, and many conversion factors. The types of problems that can be solved are kinematics of particles (including circular motion), static analysis of particles and rigid bodies in 2D, dynamic analysis of particles in 2D (excluding the dynamics of circular motion), heat, calorimetry, ideal gas, and expansion. The static and dynamic problems are entered by constructing the free body diagrams of the objects.
MorseCodr is a program for practising Morse code communication. You can connect to other users and send Morse signals that are automatically interpreted by the program. Once you become more proficient, you can reduce the amount of display and interpretation provided. It features Morse code tape display, dot/dash colouring, letter interpretation, and adjustable speed.
GCompris is an educational software suite with numerous activities for children aged 2 to 10. Some of the activities are game-orientated, but nonetheless still educational. These include computer discovery (keyboard, mouse, different mouse gestures), algebra (table memory, enumeration, double entry table, mirror image), science (the canal lock, the water cycle, the submarine, electric simulation), geography (place the country on the map), games (chess, memory, connect 4, oware, sudoku), reading practice, and others (learn to tell time, puzzles of famous paintings, vector drawing, cartoon making, etc.). It currently offers in excess of 100 activities, and more are being developed.
Organic Photovoltaic Device Model is a 1D Schottky-Read-Hall based drift diffusion model specifically designed to model organic photovoltaic (OPV) devices. It can describe non-geminate recombination via two mechanisms: free-to-trap processes via an exponential tail of trap states, and free-to-free carrier processes. The model solves the drift diffusion equations for electrons and holes, Poisson's equation to calculate the potential distribution in position space, and the Schottky-Read-Hall capture escape equations for a discretized set of energy levels. The model has been used to generate a number of publications. It can simulate the following experiments often used to characterize OPV devices: JV curves (Light/Dark), Charge extraction data (Light/Dark), and Steady state recombination data (Light/Dark).
