# Scicos > Examples

**Examples from the book**

*Modeling and Simulation in Scilab/Scicos with ScicosLab 4.4*
**Important: To run the examples, you need ScicosLab 4.4b7 or a more recent release.
**

**Examples from Chapter 7:**

- SIR model for Spread of Disease;
- Chaotic Dynamics of a Rossler attractor
- Sampled-data observer for a continuous-time state-space linear system

**Examples from other chapters:**

- Predator-prey model of sardine and shark populations, with fishing
- Discrete-time controller to control a continuous-time system
- Signal processing application
(FFT on a sliding window). This demo uses a
*CBlock*and thus can be simulated if a C compiler (e.g. gcc or VC++ on Windows) is available. - Queuing systems (Poisson arrival process and an exponential service time)
- Neuroscience application. Luteinizing hormone-releasing hormone pulse generator model introduced in the following article:
- Fluid model of TCP-like behavior. The model is presented in:
- Interactive GUI to design PD controller
- Simple batch processing example
- Batch processing: using From and To workspace blocks for exchanging data; it also contains an older version using files
- Batch processing: parameter
optimization using Scilab function
*datafit* - Inverted pendulum: animation and
control.This demo uses a
*CBlock*and thus can be simulated if a C compiler (e.g. gcc or VC++ on Windows) is available. - Electrical circuit. This is an example of Scicos implicit extension based on Modelica. This demo contains Modelica blocks and requires a C compiler
