Virtual Labs

To provide remote-access to Labs in various disciplines of Science and Engineering. These Virtual Labs would cater to students at the undergraduate level, post graduate level as well as to research scholars.

Virtual Labs will provide to the students the result of an experiment by one of the following methods (or possibly a combination)

  • Modeling the physical phenomenon by a set of equations and carrying out simulations to yield the result of the particular experiment. This can, at-the-best, provide an approximate version of the ‘real-world’ experiment.

  • Providing measured data for virtual lab experiments corresponding to the data previously obtained by measurements on an actual system.

  • Remotely triggering an experiment in an actual lab and providing the student the result of the experiment through the computer interface. This would entail carrying out the actual lab experiment remotely.

Broad Areas of Virtual Labs: Electronics & Communications, Computer Science & Engineering, Electrical Engineering, Mechanical Engineering, Chemical Engineering Biotechnology and Biomedical Engineering, Civil Engineering, Physical Sciences, Chemical Sciences

The design is typically optimised following industry best practices.

Osdag is primarily built upon Python and other Python-based FLOSS tools, such as, PyQt, OpenCascade, PythonOCC, and svgwrite. It uses SQLite for managing steel section databases. Osdag is currently under development. A beta version of Osdag containing some shear connection design modules was released in June, 2017.

OpenPLC is an initiative by FOSSEE, to engage the polytechnic, engineering and other technical students, in hands-on PLC programming experience. We envision to bridge the gap between theory centric academic training and skill based industry requirements. We use Free/Libre and Open Source Softwares - LDMicro, 4diac and PLCOpenEditor - along with affordable open-source hardware designed at IIT Bombay.

Students across engineering, polytechnic and industrial training institutes, adding up to about a million, need to be educated in PLC every year. If we include re-skilling the workforce, the number becomes even larger. In fact, the Indian Government has projected skills training for half a billion people. Most of these students lack hands-on skills as the machinery is expensive , making it mostly unaffordable for the academic institutions. Even if they are available, students are forbidden from using it out of fear that they might get into disrepair. Existing PLC’s are also restricted to predefined set of experiments and thus lack versatility. They are also closed and interiors are made inaccessible, making it a black-box.

I am not a full time teacher but teaching few students of different grades. Teacher-student relation is crucial for success of the student. My students have different gravity of subject proficiency and ability to grasp knowledge. This is why, I prefer to teach students with student-centric updated contents, written by myself focusing the ability of my students, within the academic syllabus. I never used fixed books but each time I explore new methods for explaining of the concepts to make them easy-to-understand. I wrote notes for my students in different subjects like mathematics, physics, computer, embedded system, numerical programming, concepts behind the software applications etc. which are under continuous moderation and updation (none is best, everyone must be evolved with time and space to survive). All notes and contents are compiled in one file (pdf files are available withing Books and Short Notes menu). You can download them as you required. As I already said that, none is best, this is why these notes are NOT "fully completed" and are still under updation and completion. These notes are provided under GPL licensing (as they are, may be fit or not for your requirements and are available without any commitment or guarantee).

The Chemical Processes Virtual Laboratories Portal is essentially defined as a tool to support Education.

The great changes that Higher Education is going through, namely as a result of the Bologna Process, require the discovery and development of new teaching methodologies, in particular tools aimed at the development of student autonomy. The "Web" is therefore an ideal vehicle to support this new philosophy of student-centered teaching.

This Portal contains tools developed for the Teaching of Chemical Processes, directly related to the training of Chemical Engineers. These Pedagogical Resources go through Interactive Content; Online Simulators and Virtual Experiences. Each block also contains a Library of Practical Design Cases of the Chemical Processes and Products dealt with in the respective block.

The other aspect of the Portal is of a more informative nature, with the purpose of disseminating what Chemical Engineering is, its Evolution and Areas of Application, namely among the public at the levels of Basic and Secondary Education.

The Portal will also be used in online support for Lifelong Training.
