  1. VIPRATECH An Internet Based Laboratory Course in Chemical Engineering and Unit Operations Tutorials and Remote Access Control Institute of Technical Chemistry University of Leipzig Ralf Moros ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  2. TOC • VS-C • VIPRATECH • Offline Experiments • Remote Control of Experiments • Experiences • Next Steps ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  3. VS-C – Network for Chemistry Education Federal Strategic Project in Germany 1999 – 2004 Aims • network of knowledge modules (Learning Unit ) for undergraduate studies in • chemistry • - LU: 45..60 min ; can be combined to a teaching path • using a web-based interactive teaching platform Partners Usergroups FIZ Chemie GmbH - project management - development of the interactive teaching platform 13 Universities (16 groups) - creating contents (learning units) - all chemistry disciplines involved • undergraduate students in chemistry • graduate students • -further education ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  4. Statistic • 13841 web pages • 1327 LUs • 3171 animations • …. ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  5. Technical Chemistry (Leipzig) lectures laboratory course seminars VIPRATECH Idea: online laboratory course in chemical engineering and unit operations Aim: support and improvement - carrying out a real experiment - evaluation of data - experiment manual web-based material (Experiment LUs) remote control experiments manuals Observe and control an experiment by using a standard web-browser • hardware description • experimental objectivs • theoretical backgrounds • offline experiments • online experiment • evaluation of data • interactive simulation • self control • Sharing expensive lab resources • Bringing lab experiments into the lecture hall • Enabling more flexible timetabling of labs • Sharing resources Interactive Simulation Offline Experiment Online Experiment ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  6. Experiment LU Introduction Experiment Objectives Equipment Procedure / Offline Exp. Online Experiment Evaluation / Discussion Simulation Self-controlling ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  7. Offline – Experiment • - based on real measured data • more then one user can carry out an Offline Experiment • saving real measured data • close to the real experiment Experiment Recording a real Experiment (Data, Video, Audio) Database SMIL Animation Streaming Server Internet/ Intranet Web-Browser Experiment LU – Offline Experiment • access to distant laboratory equipment (experiment) by VSC Experiment LU • Using a streaming client ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  8. Offline – Experiment ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  9. Online – Experiment : Remote Control Why?: - Sharing expensive lab resources - Bringing lab experiments into the lecture hall - Enabling more flexible timetabling of labs … Experiment Data Aquisition : TCP/IP-based hardware Observation: WEB-CAM Remote Control Server (MIFFY) Camera Server Internet/ Intranet Web-Browser Experiment LU – Online Experiment • access to distant laboratory equipment (experiment) by VSC Experiment LU • 3 web pages: user management ; scheduling ; remote access • Java-Client: Java Bean Library to create Java Clients - realized: simple scheduling, user management ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  10. Online Experiment Usermanagement Scheduling Remote access ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  11. Lab Provider - Leipzig – 6 Online Exp. Residence Time Distribution E-House Demonstration Heat Transfer 2001 2002 2003 Temperature Control Experiment Saponification of an Ester Dehydration old experiment 2004 2005 2005 ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  12. Lab Provider – Oldenburg – 1 Online Exp. Adsorption • In 2004 the adsorption experiment has • been realized • aim: building ,testing and analyzing • a network of remote controled experiments 2004 GUI ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  13. VIPRATECH: Experiences • being in use for the last 4 years • high reliability of servers (MIFFY) • easy to create servers/clients Server: 1 day; Client: 4-6 weeks • Who is using it? Students from Leipzig / Oldenburg/.. • most used experiment in 2004 :RTD Experiment (2004: 96h, 271 sessions) ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig

  14. Problems: no problems with client/server - User management/Scheduling if 2 (or more) Lab providers - Data storage; Data delivery (e-mails, ftp, download,..) Necessary to outsource service functions Next Steps: Lab Provider and Service Provider Service Provider which provides all service functions (user management, scheduling, data storage, data delivery, statistics, billing,..) more experiments (laboratory courses, automation of lab units,..) translation LUs in other languages Dream: building a network of remotely controlled experiments VIPRATECH: Experiences ICEE 2005 Gliwice/PL (c) R.Moros, ITC Leipzig
