System dynamics program with additional features for economics
Minsky enables the simulation of models (particularly from economics) defined in terms of coupled ordinary differential equations. The models are defined using a drawing canvas (rather like VisSim), and a double entry bookkeeping system known as a Godley table.
A program for fitting structural models to small angle scattering data
SASfit has been written for analyzing and plotting small angle scattering data. It can calculate integral structural parameters like radius of gyration, scattering invariant, Porod constant. Furthermore it can fit size distributions together with several form factors including different structure factors. Additionally an algorithm has been implemented, which allows to simultaneously fit several scattering curves with a common set of (global) parameters. This last option is especially important in contrast variation experiments or measurements with polarised neutrons. The global fit helps to determine fit parameters unambiguously which by analysing a single curve would be otherwise strongly correlated.

Localisation system in wireless sensor networks using ns-2
This project presents an extension to ns-2, which enables a normal user, who has basic knowledge of ns-2, to simulate localization system within a wireless network. Moreover, this project would be beneficial to researchers who want to implement new or existing localisation algorithms and anyone new to ns-2 who wish to know more about how a simulation project is built and structured. , provide more details.

Schematic circuit editor for VLSI and Mixed mode circuit simulation.
Xschem is a schematic capture program, it allows to create a hierarchical representation of circuits with a top down approach . By focusing on interconnections, hierarchy and properties a complex system (IC) can be described in terms of simpler building blocks. A VHDL, Verilog or Spice netlist can be generated from the drawn schematic, allowing the simulation of the circuit. Key feature of the program is its drawing engine written in C and using directly the Xlib drawing primitives; this gives top speed performance, even on very big circuits. I have succesfully managed to simulate complete VLSI projects with this tool, both digital (Verilog / VHDL) and analog (Spice). The user interface is built with the Tcl-Tk toolkit, tcl is also the extension language used to send commands to the program. Schematics can be printed in SVG, PNG, PDF, formats. XSCHEM runs on Linux or other Unix-likes with Xorg server and on Windows with the Cygwin layer and required tools installed.
