Part II

Make an oral presentation (of strictly 15 minutes duration) on your assignment topic. The presentation should consist of the salient features of the manufacturing process; it should also put the process in perspective with reference to other competing processes; attention should be paid to the materials aspect of the process.

The dates and times of the presentations will be decided in the class, after which, I will upload the information here.

Some suggestions

  • Under no circumstance, exceed the time limit.
  • The presentation should mostly consist of figures, tables, and data.
  • Figures and data should be properly attributed.
  • All the graphs should be neatly labelled and readable.
  • Figures should be neat and readable; if need be, also labelled.
  • If possible, completely avoid writing sentences on your slides.
  • If you are forced to have some sentences in your transparency, try only to jot down important words as bulleted points.
  • If you can not help writing sentences at all, limit to five or six lines per slide.
  • Reading from the slide is a strict no-no.
  • Under no circumstance, the written portion of your slides be more than 25% of the total number of slides.
  • If you have too much of material to cover in 15 minutes, use your judgement; present only what is relevant or some section of what you think is important.
  • Here are some web resources to help you prepare for the presentations:
  1. Making good academic presentations
  2. Preparing PPT presentations
  3. Giving an academic talk
  4. Using black/white boards
  5. Giving great talks
  6. Words of advice about giving talks
  7. Making short conference presentations and memorable posters

Part I

Write an essay (of three to five pages) on one of the following topics — as chosen by you in the class — go here for student-wise listing of the topics; the essay should
(a) describe the manufacturing process;
(b) describe the advantages and disadvantages of the processing technique;
(c) describe the type of materials for which the process is used; and,
(d) what properties of the material is affect by the process and why.
Any other interesting (for example, historical) information is welcome!

  • The assignments are due on or before 18th, February, 2009.
  • The assignments may be submitted in electronic format – as a pdf, or a word file; mail it to gurudotcoursesatgmaildotcom
  • You can also submit, if you so wish, a hard copy.
  • All write-ups will be corrected and graded; after grading, I will have office hours fixed so that I discuss the reports with each and every one of you – for comments and clarifications.
  • Please feel free to write to me in case you have queries and clarifications; you can also fix a time to have a discussion with me if you have any questions; do not hesitate to contact me at any stage (except for requesting extension of last date).

Some suggestions

  1. You may use points (a)-(d), namely, the description of the process, the relative merits and demerits, the types of materials for which the process is suitable, and the effect of the process itself on materials, as an outline for your report.
  2. Give definitions of the process themselves, if possible! If there are more than one way of defining, give all of them and let me know which one you prefer and why.
  3. You are welcome to point out any discrepancies that you notice in the literature.
  4. I will be happy if you also tell how to deal with them or get rid of them.


  1. Essay should be in your own words.
  2. Use as many figures, schematic drawings, graphs, tables and pictures as you wish – they are not counted towards the number of pages.
  3. All figures/drawings/pictures/graphs should be neatly labelled and titled.
  4. The essays should have a bibliography and/or reference section – these again are not counted towards the number of pages.
  5. The references should be in a consistent (and, standard) format.
  6. All the materials in the write-up (including data, tables, information, figures, pictures, graphs and schematic drawings) should be correctly attributed.
  7. Use plain and direct language; avoid jargons; expand all abbreviations.
  8. Make sure you list your topic, your name, and registration number on the first page of the report.

A note on helping each other

Generally, for assignments, you are expected not to help each other. However, in this course, since each of the assignments are unique, there is no such constraint. In fact, I actively encourage you to interact with each other; you may go through the reports of your friends; you may suggest references to your friends; you may correct the technical and literary aspects of your friends' reports; however, you get credit only for your report (and are completely responsible for it too!). Having said that, I would appreciate if you do not write the reports or collect materials in toto for your friends, though — allowing each person to go through the material by himself/herself and internalise the information would come handy in making presentations based on these processes for the second half of the assignment.
