Hints on Writing

Technical Papers &

Making Presentations

Kasaei 30

General PointsGeneral Points

Make attention on how to communicate effectively.

Engineers write a lot (over 40% of the work).

A successful engineer career requires strong writing skills.

Consider good writers & good speakers in research community.

“No one can be a good writer – only a good rewriter”.

Kasaei 31


Be clear & concise.

Eliminate noise during communication (it’s, fuzzy).

Focus on why you are writing.

Focus on your readers/audience.

Get to the point.

Kasaei 32


Provide accurate information.

Present your material logically.

Convey ideas & results in the least possible time & space.

Present yourself clearly (engineering is considered as a precise discipline).

Kasaei 33


Highlight your contributions.

Keep reader’s attention on the main problem.

Organize the article into sections & subsections properly to help its readability.

Spell abbreviation out in full when first used & include (parenthetically) the abbreviation [i.e., image processing(IP)].

Be consistent with notations & format.

Kasaei 34


The number of figures & tables does not come inside brackets [i.e., Figure 1, Table 5].

Figure caption appears on its below & ends with a point.

Table caption appears on its above & ends with a point.

Do not put space between a word & its subsequent comma, semi-colon, point, etc.

Kasaei 35


Avoid using apostrophe in formal writing [i.e., don’t].

Avoid writing short paragraphs.

Avoid writing lengthy sentences.

Avoid writing English or French words using Persian alphabets.

First time that the Persian translation of a professional word is used, state the English word using footnote.

The testing hardware of the rocket shown in Figure 8 has five main components: camera, digitizer, computer, I/O interface, and mechanical interface. Commands are generated by the computer, then passed through the I/O interface to the mechanized interface where the keyboard of the ICU is operated. The display of the ICU is read with a television camera and then digitized. This information is then manipulated by the computer to direct the next command.

Points on Writing a Scientific ManuscriptPoints on Writing a Scientific Manuscript

Technical papers usually consist of the following components:

1. Title – should be concise & to the point, contain main keywords, denote the specialty of the work, all in less than about 10 words (or 3 lines). Usually in uppercase & boldface.

2. Abstract – summary of the paper (not more that 150~200 words) including a brief description of the problem, its importance, related existing work, main proposed solution, & conclusions. No cited references or displayed equations.Written in one paragraph.

Kasaei 89


3. Keywords – selected for computerized search.Contains about 4~6 words (in the order of importance).

4. Introduction – defines the scope & limitations of the work.It contains the definition, scientific importance, historical background, & relevance to other areas. Properly describe & reference the related work. Give your description about other algorithms.Briefly describe the proposed solution, how it is different from & superior to other existing solutions.Clearly state the conclusion. Last paragraph is a summary of the paper structure.

Kasaei 90


5. Proposed Algorithm – describes the proposed solution. Highlight your contributions. State the model assumptions clearly. Use flowcharts & figures to illustrate the solution.

6. Experimental Results – give a complete performance analysis (not Simulation Results). State resource characteristics (size, resolution, etc.).Use figures, tables & charts to interpret results. Chosen parameter values should make sense. Show the average values & confidence intervals. Describe simulation time, computer type, & the used language.

Kasaei 91


7. Figures – place immediately after where they are referred to, at the top of the next page, or at the end of the paper. Some space should be left above & below each figure. Should be readable without relying on the accompanying description in the text. All symbols should be explained in the legend. Caption appears in below & ends with a point.Previously published material must be accompanied by written permission from the author & publisher.Figures should be numbered sequentially in Arabic numerals. Figure numbers should not appear inside parenthesis.

Kasaei 92


8. Tables – insert in the text as close to the point of reference as possible.Should be readable without relying on the

accompanying description in the text.Some space should be left above & below the table.Tables should be numbered sequentially in Arabic numerals.Numbers should not appear inside parenthesis.Captions are to be centralized above them.All used symbols should be described.

Kasaei 93


9. Equations – number consequently in each section, with the number set flush right & enclosed in parentheses.Refer to equations using parenthesis (e.g., Eq. (4.1)).

10. Conclusions – summarizes what you have done, the difficulties, & concludes based on results. Include the future research direction.Preferably, written in one paragraph.

11. Acknowledgement – comes before the appendix if any.Should be unnumbered.

1. Funding information may also be included.

Kasaei 94


12. Appendix – contains materials deemed inessential to understanding but included for completeness, & detailed mathematical proofs. Comes before the References.With more that one appendix, numbered alphabetically.Number displayed equations in the way, e.g. (A.1).

13. References – use more readily available papers. Follow the determined standard bibliography format precisely.All should be cited in the text.Should be unnumbered.

Kasaei 95

Submitting a Scientific ManuscriptSubmitting a Scientific Manuscript

Originality – paper should not be either published or considered for publication in another journal or conference.

Submission – submit, most, papers electronically in .ps, .dvi, or .pdf formats as attachments to an email message to the Editor-in-Chief.Indicate author in contact’s email, postal address, & the fax number.

Kasaei 96

Submitting a Scientific ManuscriptSubmitting a Scientific Manuscript

Acknowledgement & Refereeing – the Editor-in-Chief will acknowledge receipt of the submitted paper. If the Editor-in-Chief considers the paper to be appropriate, it will be refereed.

Copyright – for accepted papers for publications, the authors are assumed to have the copyright transferred to the publisher.

Submission of Final Version – the final version (the camera ready version) should exactly follow the style file provided by the publisher.

Presentation PointsPresentation Points

1. Visit the venue beforehand to get familiar with room’s layout & the equipment.

2. Establish rapport with audience by speaking to them for a couple of minutes (summarize the result, how this talk relates to other talks in the session, how it relates to the keynote of the conference, how you got interested in this topic). Get the audience to focus on the topic rather than on the speaker or the screen.

Kasaei 113


3. Project your voice relative to the room & audience size.

3. Aim for a normal conversation speed.

4. Vary your pace & pitch.

5. Avoid blocking anyone’s view continuously.

Kasaei 114


7. Stand far enough to the side to prevent screen blocking.

8. Avoid reading from slides.

9. Repeat key points – “tell your listeners what you are going to tell them, & finally tell them what you have told them”.

10. Use a pointer to focus your audience’s attention on your graphics.

Kasaei 115


11. Accept your nervousness.

Take some deep breaths before entering the room.

Note that you have worked hard on your talk & have practiced delivering it.

Try to concentrate on your topic rather than yourself.

Try to have a few friends or colleagues in the audience.

Look at friendly faces. ☺

Kasaei 116


12. Have an “Outline” slide.

13. Organize the slides as precise & as logical as possible.

14. Presentation should not follow the paper exactly.

15. You usually have 20 min. for presentation & 5 min. for questions & answers. Explain the goal, importance of the work, key ideas of the solution, how it is different (& hopefully) better than existing solutions.

Kasaei 117


16. Presentation should not deviate too much from paper either.

17. Maintain eye contact. Talk to the audience not to the viewgraph. Address different parts of the room.

18. When preparing slides:Make sure that the visual aids are readable. Use a bit of color to highlight important points.Use figures, block diagrams, flow charts, images, etc.Bring transparencies, other diskettes, … as backups.

Kasaei 118


19. Do not put too many ideas on the same slide.

19. Everything on the slide should be explained.

20. Do not put too much mathematics on the slides. Just enough mathematics should be presented to bring the key point across. The focus should be on the results. Use figures (plots) to bring the points across.

Kasaei 119


22. Have at least one “Contributions” slide.

23. Have a “Conclusion & Future Work” slide.

24. Have a “List of Publication” slide.

25. Have some extra slides containing some details of the work, to use in case some questions arose.

Kasaei 120


26. Be ready for difficult or unexpected questions.

If there is any difficulty with a particular question do not be overly defensive.

A difficult question can be turned into an idea for future research.

Repeat the question.

Simply say “I don’t know”.

Offer to talk with the questioner after your talk.

Do not say things that you are not absolutely sure of.

By the late Middle Ages, cities throughout Europe were building Gothic cathedrals. The only way, however, that architects could test a new design was to build the cathedral, a process that took more than forty years. Unfortunately, many cathedrals caved in during or after construction. What took forty years to test in the Middle Ages could have been done in minutes on a supercomputer.

Mount St. Helens erupted on May 18, 1980. A cloud of hot rock and gas surged northward from its collapsing slope. The cloud devastated more than 500 square kilometers of forests and lakes. The effects of Mount St. Helens were well documented with geophysical instruments. The origin of the eruption is notwell understood. Volcanic explosions are driven by a rapid expansion of steam. Some scientists believe the steam comes from groundwater heated by the magma. Other scientists believe the steam comes from water originally dissolved in the magma. We need to understand the source of steam in volcanic eruptions. We need to determine how much water the magma contains.

Non-words and nonsensical groupingsof words also cause problems

Whichever design you choose is (alright / all right) with me.

(Irregardless / Regardless) of the shipping delay, the work will stop because of the strike.

Applying that set of constraints is a (most unique / unique / very unique) way to approach the problem.

The serum had (alot / a lot) of side effects.

1. Hyphenated Words – If the first word is used as an adjective, no hyphen is necessary (e.g., first generated). If the first word is a noun, you need to hyphenate (e.g., range-limited). If the second word is a gerund do not hyphenate (e.g., cell splitting).

Kasaei 198


2. Numbers:

2.1. Use numerals for technical quantities, especially if a unit of measurement is included:3 feet12 grams43.2 square miles

2.2. Use numerals for non-technical quantities of 10 or more:300 persons12 wheals35% increase

Kasaei 199


2.3. Use words for non-technical quantities of fewer than 10:Three personsSix wheals

2.4. Use both words & numerals for:Back-to-back numbers (e.g., seven 3-inch screws)Addresses (e.g., 3801 Fifteen Street)

Kasaei 200


2.5. Special Cases:

Use words to begin a sentence (e.g., Thirty-seven acres was …)

Write out fractions, except if they are linked to technical unites (e.g., two-thirds of the members, but 1/2 hp)

Fractional numbers are considered plurals (e.g., 0.5 meters).

Write out approximations (e.g., about two million trees)

Kasaei 201

Common Errors

Use numerals for titles of figures, tables, & page numbers (e.g., Figure 1, Table 2, page 3)

Use numerals for decimals (e.g., 0.7)

Use numerals for time if A.M. or P.M. is used (e.g., 6:10 A.M., but six o’clock)

3. When abbreviating (initialisms/initialization not acronyms), if the word starts with a vowel (namely a, e, i, o, u) use the article “an” (e.g., an LCD, an MRI, a radar).

Kasaei 202


4. First time a symbol is used, explain what it refers to (e.g., Wavelet Transform (WT)).Avoid repeating the refer.

4. Avoid negative words like “not”, “un”, “non” as well as double negative like “not uninteresting” as much as possible. Use “invalid” instead of “not valid” & “violating” instead of “not satisfying”.

Kasaei 203


6. Phrase “a lot of” is used for uncountable objects (e.g., a lot of money). For countable objects use the word “many” (e.g., many users). The same goes for the word “a large amount”.

7. Say “greatly improves” rather than “highly improves” of “largely improves”.

8. Say “contrary to” rather than “in contrary to”.

Kasaei 204


9. Words “work” & “research” are already in plural.

10. Do not use abbreviation/informal forms like “don’t”.

11. Avoid using multiple superlatives (e.g., very best).

12. Do not start a sentence with “also”. Use “Besides”, “Moreover”, “In addition” instead.

Kasaei 205


13. Say “comprises” or “consists of” rather than “comprises of”.

14. Words “figure”, “table”, “theorem”, “lemma”, “chapter”, & “section” may be used as proper or common nouns. Proper nouns must be capitalized (e.g., Figure 1 illustrates … ; but, in this figure …). Spell in full if they are the first word of the sentence.

15. Semi-colons are used to break up groups of objects (e.g., Set A …; Set B …; Set C …).

Kasaei 206


16. Avoid repeated usage (e.g., than that in, the former, the latter).

17. Most abbreviations do not take plurals (e.g., 3 lb)

18. Be consistent with English & American spelling.

19. Avoid writing French words with Persian alphabets.

Research ProcedureResearch Procedure

Kasaei 212


A rough outline of a research program is:

1. Ideation2. Background Research3. Topic Selection4. Initial Research & Proposal Development5. Proposal Defence6. Research Completion (often validating a concept

developed in the proposal)7. Thesis Defence8. Publication

Kasaei 213


This process is not necessarily linear.

Topic can be pre-selected because of the interests of the student and/or the supervisor.

Publications & conference presentations often come directly out of the background research process.

Publications often lead to innovative ways of describing issues that will eventually lead to field or laboratory studies to validate the proposal.

Kasaei 214


Learning & Accumulating Knowledgeis the fundamental activity, & relates to most of the process steps in the research program. This section reviews some of the most relevant aspects of this activity.

Literature ReviewKey Authors, Papers, & JournalsIn every field there are key authors & papers that you will see as your review process proceeds.

Kasaei 215


Finding good review articles is like finding gold nuggets during your literature review. These are often published by Ph.D. students, who have gone through a great deal of effort to describe previous research in the field in which they are working.

Recently there has been & continues to be a huge transformation in the availability of journals, as well as many electronic books, online.

Kasaei 216


How does one make use of this great abundance of research?

1. Be selective in your choice.2. Do not print all the articles on hard copy.3. Download & store the papers you choose on your

computer & read them there if possible. Papers that are very important to your research probably should be printed out because most of us are better able to handle detailed study of hard copy than material on computer screens.

Kasaei 217


Keep Track of all These ArticlesFrom the very beginning set up a database of references(that you can select from at will & can reference from the text of your thesis & other publications).

Associations & ConferencesAn excellent way to keep your knowledge updated is to belong to an association of researchers active in your field, networking with them, & attending conferenceswhere you can be exposed to the latest advances, trade ideas & experiences with your peers.

Kasaei 218


What do researchers get out of the conferences?

1. Exposure to the latest research on current issues.2. Opportunity to meet with other researchers with similar

interests.3. Availability of job market for both new & established

researchers.

Kasaei 219


PublishingPublication is the end result of the work that goes into research. This is not the only end result of the research, teaching is also greatly enhanced by knowledge gained in research activities that not only push the envelope of existing knowledge, but also forces researchers to keep up-to-date on the latest works.

Kasaei 220


“publish or perish” syndromeThat is, if you are hired after graduation into a tenure track faculty position, you will be required to turn out an acceptable amount of research over a limited time, in order to keep your job. If you have a couple of good articles published or accepted, by the time you complete your studies, this greatly enhances the likelihood of finding a good position.

Kasaei 221


If you plan to submit to a journal, be sure to check the journal’s “instructions to authors” for acceptable topics, length, formatting, how to handle diagrams, references,etc.Also check a sample of articles that have appeared in the journal, & these may tell you more.
