<h3 id="sec2.4">Mateusz Paprocki,  SymPy (2 hrs)</h3>

<ul>

	<li>

	SymPy is a pure Python library for symbolic mathematics. It aims to become a

	full-featured computer algebra system (CAS) while keeping the code as simple

	as possible in order to be comprehensible and easily extensible. SymPy is

	written entirely in Python and does not require any external libraries.

	</li>

	<li>

	In this tutorial we will introduce attendees to SymPy. We will start by

	showing how to install and run SymPy. Then we will proceed with the basics

	of constructing and manipulating mathematical expressions in SymPy. We will

	also discuss the most common issues and differences from other computer

	algebra systems, and how to deal with them. We will also show how to solve

	simple, yet illustrative mathematical problems using SymPy.

	</li>

	<li>

	Outline

		<ul>

			<li>Installing, configuring and running SymPy.</li>

			<li>Basics of mathematical expressions:

 				<ul>

 					<li>symbols, dummy symbols</li>

 					<li>constructing expressions</li>

 					<li>expression traversal</li>

 					<li>pattern matching</li>

				</ul>

			</li>

			<li>Common issues, pitfalls and differences with other CAS:

				<ul>

					<li>1/3 is not a rational number</li>

 					<li>why you shouldn't write 10**(-1000)</li>

 					<li>issues with caching of computation results</li>

				</ul>

			</li>

			<li>Using built-in and implementing customized printers.</li>

			<li>Arbitrary precision numerical computing.</li>

<h3 id="sec2.5">Ole Nielsen: Mapping and Geoprocessing with Python (2 hrs)</h3>

<ul>

	<li>

	Putting information on a map and analyzing spatial data are fundamental to a

 	wide range of areas such as navigation, working with climate or geological

 	data, disaster management, presentation of modelling results, demographics,

 	social networking etc. However, making and viewing maps is just the tip of

 	the iceberg: to communicate spatial information much work is needed under

 	the hood to read, write, manipulate and process the data underpinning the

	maps.

	</li>

	<li>

	T This tutorial will give a practical introduction to tools and techniques

 	available for processing spatial information and, through hands-on

	 exercises, give the participants a sense of how to manipulate spatial data

	 using Python. Depending on time, topics covered include reading and writing

	 of important data formats for both raster and vector data, looking at the

 	layers with qgis, awareness of issues with datums and projections,

 	calculating area and centroids of polygons, performance enhancement using

 	vector operations, numerical stability issues, calculation of distance

	 between points on the surface of Earth, interpolation from raster grids to

	 points etc. The tutorial has been developed for Ubuntu Linux 11.04/11.10 and

	 will provide source code, tests and data for this platform. However, the

	 content and messages should be general and apply to any self-respecting

	 platform.

	</li>

	<li>

	I assume that participants know how to write and run Python scripts and are

 	OK having a crack at implementing simple numerical operations such as

 	summations in Python. I don't assume any previous knowledge of mapping or

 	Geographic Information Systems (GIS). The tutorial depends on the

 	packages qgis and gdal-bin as well as the python dependencies python-numpy

 	and python-gdal which are preloaded on the distributed live-DVD. The

 	tutorial material itself will be available in the Subversion repository

 	http://oles-tutorials.googlecode.com/svn/trunk/scipy2011 and also on a USB

 	stick that I will bring along.		

	</li>

	<li>

	If you have some spatial data you want to manipulate in Python feel free to

 	bring it along and grab me during a lunch break.

	</li>

<h3 id="sec2.6">Eric Jones: Traits + Traits UI (2 hrs)</h3> 

<ul>

	<li>

	Enthought’s traits package provides for a powerful object model which 

	provides a host of useful functionality with a clean and expressive syntax.  

	It is an open source library and forms the basis of the Enthought Tool Suite and many of 

	Enthought’s internal commercial projects.  In this tutorial we will cover the basics of using 

	Traits along with the UI library TraitsUI which makes it very easy to build powerful and 

	interactive, user interfaces using Traits.

	</li>

</ul>

<h3 id="sec2.7">Prabhu Ramachandran and Gael Varoquaux, Mayavi for 3D visualization (2 hrs)</h3>

<ul>

	<li>

	At the end of this tutorial attendees will learn how to visualize numpy

	arrays using Mayavi's mlab interface.  They will also learn enough about

	mayavi to be able to create their own simple datasets and visualize

	them.  If this tutorial follows one on traits, then attendees will learn

	how easy it is to embed 3D visualization in their own application UIs

	(provided they are written in wxPython or PyQt).

	</li>

	<li>

	In this tutorial, we first provide a rapid overview of Mayavi_ and its

	features.  We then move on to using Mayavi via IPython_ and mlab.  This

	is done in a hands-on fashion and introduces the audience to visualizing

	numpy arrays and the basic mayavi visualization pipeline.  We then

	introduce the audience to the basic objects and data sources used in

	Mayavi.  We end with an example of creating custom dialogs using Traits

	and embedding 3D visualization in these dialogs with Mayavi.

	</li>

	<li>

	Packages required

		<ul>

			<li><a href="http://code.enthought.com/projects/mayavi">Mayavi</a></li>

			<li><a href="http://ipython.scipy.org">IPython</a></li>

			<li><a href="http://code.enthought.com/projects/traits">Traits</a></li>

			<li>numpy, scipy</li>

		</ul>

<h3 id="sec2.8">Puneeth Chaganti, Sage introduction/tutorial: (1 hr)</h3>

<ul>

	<li>This tutorial will feature a demonstration and a brief review of some of the capabilities of the <a href="http://www.sagemath.org">Sage notebook</a>.</li>

	<li>A rough schedule of the talk would be as follows:

		<ul>

			<li>Introduction</li>

			<li>Starting the server</li>

			<li>The UI</li>

			<li>Getting Help</li>

			<li>Overview of what's available in Sage

				<ul>

					<li>Basic Algebra</li>

					<li>Basic Calculus</li>

					<li>Basic Plotting</li>

				</ul>

	</li>

		</ul>

	</li>

</ul>

<h3 id="sec2.9">Pankaj Pandey and Prabhu Ramachandran, An introduction to Cython (1 hrs)</h3>

<ul>

	<li>

	At some level, Cython (http://www.cython.org) can be thought of a Python to C compiler.  

	It allows someone to write extension modules in a language very similar to Python and 

	therefore makes it rather easy to write C-extensions.  In this tutorial we will cover 

	the basics of building extension modules with Cython.

	</li>

	<li>

		Package requirements: You will require to have Cython, the 

		Python development headers and a working C-compiler to run the hands-on exercises.

	</li>

</ul>
