Axel/Stefan:
  Automatic loading of Reflex information in ROOT files

  Like automatic loading for dictionary libraries it should be also possible
  to allow automatic loading of Reflex information contained in ROOT files.
  The idea is to implement in Reflex a mechanism which will allow to do that.
  E.g. the information contained in rootmap files could be used via the
  PluginService to load the reflection information in an automatic way.
  The student will have to combine the PluginService with the ROOT I/O and
  enable population of Reflex via this mechanism. This will be also benefitial
  for BOOT in the longterm.

  ROOT: GUI Developments

The ROOT Graphical User Interface (GUI) classes are fully cross-platform
and provide standard components for an application environment with
common 'look and feel'. This availability of the basic user interface
elements assigns many tasks to be done for the ROOT users in the future.
The ROOT GUI work package can offer the following software development
in user interface classes:

- Multiple line labels and tooltips - new development related to the
label text with new-line delimiters, different font styles within lines,
hyperlinks features.

- Drag and Drop - a modern and intuitive way of transferring information
within different ROOT applications; an addition to the clipboard support
for moving and copying data in ROOT.

- Table/Grid widget - new development related to a GUI widget containing
multiple sections of rows and columns, where each section may be
independently scrolled and resized by dragging its borders.

Training recommended: see ROOT User's Guide and http://root.cern.ch

Content of the project: 100% computing

Expected training value of the project: experience with designing user
interface and application programming.

Computing skills required: OO design and programming in C++; use of
different operating systems (Linux, Windows)

Student: computer scientist

Supervisor: Ilka Antcheva
Second supervisor: Fons Rademakers


Lorenzo
  ROOT:Math Libraries development

The candidate will be integrated in the team of the Math work package

of the ROOT project.  This team has the responsibility of providing

the basic mathematical libraries to physicists developing reconstruction

and analysis programs and give support to them.
The main task of the student will be to perform unit and validation tests of new
 implementation of numerical and statistical algorithms implemented in the new R
OOT mathematical library. In addition he will work on simple examples and tutori
als which will be published on the Web site.

Main Supervisor: Lorenzo Moneta
Second Supervisor: ????

Student Profile: Mathematician/Physicist/Computing Scientist

Skills required: some basic knowledge of C++, applied mathematics and/or
statistics.

Training value:
learn numerical computation and  statistical methods  and improve the
knowledge of object oriented languages like C++


Fons

Implement a generic task processor in PROOF.
Extend PROOF to process generic task in parallel.
Implement a TPacketizerTask which takes care of task processing.

ROOT:Graphics: 2-D and 3-D
  ==========================
 
  Graphics is an essential component of any data analysis and data 
  presentation system. As such ROOT is not an exception: The ROOT's 
  graphical libraries provide support of many different functions including 
  basic graphics, high-level visualization techniques, output on files, 3D 
  viewing etc. They use well-known world standards to render graphics on 
  screen (X11, GDK, Qt, and OpenGL), to produce high-quality output files 
  (PostScript, PDF), and to generate images for Web publishing (SVG, GIF,
  JPEG, etc.). Many techniques allow visualization of all the basic ROOT
  data types (e.g., histograms, Ntuples, `trees', graphs, analytic 
  functions, cuts), projected in different dimensions and coordinate systems
  (2D, pseudo 3D, full 3D, 4D) and can be produced in high quality for
  publication purposes.
 
  In this context the ROOT Graphics Work Package can offer several projects 
  for a summer student all related to data's graphics representation. They 
  are of various kind:
    * Improvements in existing C++ classes,
    * Development of new C++ classes,
    * Framework improvement (graphics test suite, examples),
    * Basic 2D graphics,
    * Output (PDF, SVG),
    * High level 2D graphics or 3D graphics.
  One project may cover one or several of these aspects.
 
  Some projects may also have some connections with the graphical user 
  interface (GUI): High level graphics classes like TGraphPolar, TPie etc 
  need specific editors which are still missing. Also some existing editors 
  need to be completed.
 
  Other specific requirement:
     The candidates should be fluent in C/C++ programming language.
     Some knowledge in computer graphics and GUI would be also very useful.
