Review: XCTL during last year

1
Review XCTL during last year

• Kay Schuetzler

2
Agenda

• Introduction to the XCTL system
• State in August 2003
• Work done up to now
• Current work
• Diploma theses at HU

3
Introduction to the XCTL system

• Hardware controlling software used in
  experimental physics
• Usage area
• Analysis of semiconductor structures
• Displaying investigated structures in graphical
  form

4
Example usage of XCTL
collimator
photo plate
?
sample
sample holder
X-ray tube
5
Presenting structureson a photo
Picture of GaSb-islands on an AlSb-substrate

• Measuring method
• Topography

6
Presenting structuresas graphics
Graphic of an atom core with its e-shell

• Measuring method
• Diffractometry/Reflectometry

7
Features of XCTL

• Control motors (e.g. on sample holder)
• Control x-ray detecting devices
• Control measurement processes
• Adjust samples (before and during measurements)
• Evaluate and display results (during and after
  measurements)

8
State in August 2003

• Freshly ported from 16-Bit WINDOWS and Borland
  C to 32-Bit WINDOWS and Microsoft Visual C
• Reengineering of user interfaces started
• Plovdiv group Refactoring of use case LineScan
  finished and refactoring of use case AreaScan
  started
• Parts of multimedia presentation of XCTL and its
  domain finished

9
Porting activities

• A lot of successful tests
• Some not so successful
• By now, porting activities successfully ended
• XCTL 32-Bit WINDOWS application to be further
  developed with Microsoft Visual C 6.0 IDE

10
Reengineering ofuser interfaces

• Redesign of user interfaces of use case Manual
  Adjustment
• More ergonomic versions with less errors
• Separating functional component from user
  interface for use case Topography
• Easier to maintain, easier to understand
• Both tasks finished

11
Multimedia presentation

• Multimedia presentation application grew and
  still grows
• By now, nearly 80 finished
• Assumed to be finished in December (this year! ?)

12
Work done in Plovdiv

• Presentation at this workshop
• A. StoyanovaA refactoring process based on the
  experience with XCTL
• Used newly developed English version of ATOS
• K. SchuetzlerTesting tool ATOSprinciples and
  experience

13
Current work

• Moved from directly reworking XCTL software to
  considering its environment
• Testing ATOS - Enhancement
• Metrics New tool by two of our students
• Testing the correctness of user interfaces
• Multimedia presentation

14
Diploma theses at HU

• T. Kullmann, G. Reinecker
• Decomposition of software systems into functional
  component and user interface in forward and
  reengineering
• Jan Picard
• Software reconstruction through refactoring
• H. Seffler, R. Treysse
• A metrics and instrumentation tool for Java and
  C
• M. Wolf
• Correctness of user interfaces
• some student research projects
