General Issues

Why a lecture about writing?

Surely, any literate can write. Why talk about ‘Writing’?

Any body can sing. But, can we get an audience? Writing is for communication? Can we get readers?

‘Writing’ is a SKILL.

Good writing is an ART. More so ‘Technical Writing’.

There may be those who are born or gifted writers.

Others have to LEARN and PRACTICE.

Example of an old Technical PaperFrom: Philosophical Transactions of the Royal Society 41, 162-66 (1739)

An Experiment to prove, that Water, when agitated by Fire, is infinitely more elastic than Air in the same circumstances; by the late Revd John Clayton, Dean of Kildare in Ireland

Sir Thomas Proby having heard of a new Digester, which I contrived, had a Desire to see it, and some experiments made therein. I had a small one which I designed only for an inward Cylinder; this I could easily put in my Pocket: Wherefore , going to pay him a Visit at … … , but that the Vessel was very weak, and I feared would not endure the Pressure of so violent a Heat; yet something desirous to have the Experiment tried; I said I was ready to venture my Vessel: ……. into the Fire about half way; and in about three Minutes time I found it raised to a great Heat; ….. . Scare had I done speaking, and Sir Thomas thereupon moved his Chair to avoid Danger; ….. , it burst as a Musquet had gone off. A Maid that was gone a milking, heard it considerable Distance; the Servants said it shook the House. The Bottom ….

Example of a modern Technical PaperFrom: Proceedings of the Royal Society 457, 1533-1554 (2001)

Decay of a three-dimensional vortex in an enclosureBy Name of the Author(s), Institution, Address, e-mail

Received 7 January 2000; revised 17 October 2000; accepted 6 December 2000

Abstract: …………………..Keywords: vortex motion; viscous decay; closed streamlines; cavity; toroidal surface

___________________________________________________________________________________________

1.IntroductionAlthough many studies exist of both inviscid and viscous free vortices, not many exist of confined three-dimensional vortex motions, despite these being of fundamental and practical interest. Confined flows, of course, have special complications brought about by, for instance, the presence of corner or secondary vortices and separation and reattachment points; moreover if the initial state is turbulent, transition to the laminar state will occur with the decay of the vortex motion. It is clear that with all these complexity one will………

Basic Requirements

Good Vs Bad writing: This is subjective. No one is perfect.

‘writing’ should meet minimum acceptable standard.

• Avoid spelling errors (like bad notes in music)

Use built-in Dictionary but don’t rely wholly on it.

“Following procedure followed for performing model analysis”“There are too birds on the tree”

Select appropriate version of “English” for spell checking

“Load and boundary conditions applied on the model is shown in the figure bellow”

“The following steps are used in preparing FE model for thermal analysisodal analysis”

Patiently search. Proof Read.

Some Guidelines regarding Flow: Use appropriate words. Avoid verbose and bombastic language. Each sentence must have a main verb (action). Use simple declarative sentences. Let the sentences be inter-connected. Each paragraph contains one main idea. Paragraphs must be inter-connected. (Explain with 1,2,3 above as an example.)

Avoid grammatical errors (like a bad tune) – Study and practise.

Maintain a good flow of language. (like a good song) – This comes by practice. Write and re-write. Change the sequence of sentences. Write in several ways. Read loudly. Select what you feel as the best.

“The operating speed of the impeller is 24000 rpm (revolutions per minute) that is the exiting frequency of the impeller system is the operating speed in per second. Hence the exciting frequency in revolution per second is 4500 rps (Hz)”.

Use Simple declarative sentences. Note the irony:

“He should be especially careful to shun the long, meandering sentence that is crammed with obscurely related phrases and clauses, in which the subject and predicate seem hopelessly to be searching for each other and the verb has a kind of floating object.”

- from Dwight E Gray, “So you have to write a technical report”, ARP, Washington, 1970. Ch.1, p.3.

Avoid phrases like:Coming to the point… It is important to note…All in all…To reiterate…It can’t be overemphasized that …We have to note especially that …Can I ask you a question? – This itself is a question.

Some examples of bad usage:

Ex. 1: ‘The number of tasks are …’ (noun in singular, verb in plural)

‘Data’: is it singular or plural?

Ex. 2: ‘although the pressure was very high, it is within acceptable limits’; (tense mismatch)

Ex. 3. It was aim to study the characteristics of the comparator response…

The aim was to study …

Ex.4. “It was also verified for it’s various building blocks were studied for their designed values, which was satisfactory for the output response.” Too many verbs in a single sentence. (sentence too long, too-many verbs with mixed number)

It was verified if

( a ) the building blocks meet the design specifications and

(b ) the output gives a satisfactory response.

Elements of Technical Writing Purpose: Convey Information in clear, precise, un-ambiguous, and technically sound language. Technical writing consists of technical terms.

Vocabulary of technical terms. A student of distinction scores because he/she uses technical terms precisely. Technical terms in Cricket:

“Lindwall is having a fast run-up for his bowling.

He has one long-leg, one short-leg, one square-leg.”

Maintain a Handbook for Glossary of Technical Terms. Whenever you come across a new technical term, enter it with definition, example of usage with Figure, symbol, unit, cross reference to related words.

Examples: Understand the subtle difference between similar technical terms.

sound, acoustic, vibration; ultra-sound, super-sonic.

Is this a valid question: ‘What is the velocity of sound waves?’

time, duration, interval, delay;

Force, pressure, stress,

Strain, elongation, displacement, deformation, amplitude

VKB MDD

21M.S.Ramaiah School of Advanced Studies

Elements of Technical Writing Vocabulary of technical terms (cont.)

Multi-dimensional Vs multi-channel

Factorization Vs Decomposition; ‘The factors are…’ Vs ‘The components are…’

Analog Vs Continuous; Analog Vs Analogue; Discrete Vs Digital;

Convolution Vs Correlation

‘waveform of an amplifier is…’;

‘motor is reversed…’;

‘logarithmic bandwidth’ – is this a valid technical term?’

…which keeps the residual echo minimum; - is this correct?

‘with certain assumptions on certain circumstances and constraints’; (too vague)

Use the appropriate word based on the context.

50% of the learning/teaching effort goes towards building the technical vocabulary. Knowledge of the technical terms must be available at finger tips. A student’s level of confidence depends on this knowledge.

Elements of Technical Writing

Use of Unit. What is the time? six twenty. 620. It makes sense.

what is the speed? 600. 600 what? 600 mph or 600 kmph or 600 rpm?

Always specify the Unit along with the number. Use appropriate unit based on the context. In place of 0.003 meter, use 3 mm for easy readability. But while solving problems use appropriate unit. While entering data as input into a program, use the appropriate unit. Units are always in singular (exception ‘feet’?). In case of Units having proper names the first letter is capitalized (convention varies). Ex: Hz, dB. Abbreviations for ‘milli’, ‘kilo’ etc are always in lower case. Ex: kHz, 3 mm. Sometimes a subtle distinction is made between meter-squared Vs sq-meter (area).

When a sequence of numbers is given, specify unit only ones: 100, 1000 and 4000 Hz not 100 Hz, 1000 Hz and 4000 Hz. ( is the previous sentence correct?)

Dimension: Dimension of speed is the same (L/T) irrespective of the Unit. A knowledge of Dimension helps in verifying the correctness of a formula.

Which formula is correct: f=c or c = ff: frequency = 1/T. c = L/T. = L.

Elements of Technical Writing

Symbols and Mathematical Formulae:

Mathematics is the queen of science. It is a short hand notation.

Physical situation > Mathematical model > Solution > Interpretation in physical terms.(Give example here: Grand father’s age is the square of grand-son’s age; 2*GF+GS=78.)

Define the symbol the very first time it is used. Use symbols consistently through out the presentation. Ex: frequency is represented by the symbol ‘f’ ( or ). Note the difference between the angular frequency (radians per sec) and the linear frequency f (Hz).

Use appropriate symbols for Scalars, Vectors, Matrices. Define the convention.

Transforms are generally shown in Upper case. F(), T(s), H(z).

Take care of sub-scripts and super-scripts. Use parenthesis to properly group the terms. Numerator and denominator are to be properly separated.

Tables: are used to show experimental data where ( a ) one or more of the variables is non-mathematical or ( b ) there are too many variables or ( c ) the dependence amongst the various variables is not obvious (no underlying theory)

or ( d ) the data is too sparse.

Ex: Frequency of occurrence of different letters; Confusion matrices in listening tests; Velocity of acoustic waves in different media.

Generalization can’t be drawn from the results presented in a Table. Sometimes Bar graphs, pie-charts are used to visualize data in a Table.

Elements of Technical Writing

Graphs: are used where the variables (a) take on numerical values and (b) are grouped as dependent and independent. Example: Filter response. Independent variable, frequency, is shown on x-axis. Dependent variable, gain, is shown on the y-axis. Proper units and range must be chosen to illustrate the functionality. Use ‘log’ scale when the range is very large. Ex: Frequency range over 10 to 100,000 Hz. Sometimes a family of curves is shown. Filter response also depends on the ‘order of the filter’. This is shown as a ‘parameter’. Throughout the experiment the value of the parameter remains the same. Experimentally measured data are to be shown as discrete points along with the fitted curve. The following graphs represent filter responses of first order LPF and 2nd order HPF. What is wrong?

Selecting a Project Don’t be too ambitious - selecting a big project that can’t be handled within the

available time reflects badly – (give examples) - Don’t select a trivial project either – Discuss with various persons –

What Employers look for in a project? Important Points to remember:

DEPTH – QUALITY – COMPLETENESS – KNOWLEDGE ACQUIRED – SKILLS ACQUIRED – PRESENTATION SKILLS (Oral and Written)

Depth: Thoroughly familiar with all the terms / concepts /formulae used.

Quality: Work must show the ability to solve a problem – know the difference between reality and model: Resistor Vs Resistance? (More about it later).

Completeness: Making a big claim in the Title of the project, but within the report stating that due to lack of time only a part could be done - not a good practice.

Knowledge/Skills Acquired: Employers are going to test the knowledge relating to the problem area – You must become an expert in the chosen problem area (sub-area) – be able to teach /guide / lecture -

Writing the Introduction

Introduction has three principal parts

A Scope and subject matter

Amplification of the Title – What the report is all about – Limits of coverage

B Purpose, Audience

amplification of the preface if there is one - Purpose of the report not the purpose of the experiment – Is it a user’s manual, is it a technical report; what background is assumed on the part of the reader – what are the limits of the study -

C Plan of the work

amplification of the Contents - an overview of the report – how things are organized and why so –

Length of the Introduction: 10 to 15%.

DON’T: Start with a long history, very general discussion about the subject matter.

DO: Let the reader to know the subject matter of the report immediately.

 “VLSI is an exciting and important area in electronics. Over the past decade it has emerged as …”

   “Security is a vital issue of national importance. Today’s technology has advanced …”

 Instead, use direct approach:

“This report presents in detail the VLSI design of a first order Butterworth analog filter for audio applications.”

“A digital image processing algorithm is presented that verifies the image of the human face recorded using a web camera against images stored in an existing database. The algorithm is based on …”

Problem

Problem is broadly specified by the Programme Manager.

But narrow down the problem.

Ex: where do you live? – In solar system, on earth, in India, in Karnataka, … Subject > Area > Topic > Problem (Area )> Your Problem (sub-area)

Electronics > Digital Signal Processing > Image Processing > Face Recognition

Face Recognition: Is it identification or Verification?Technique: What Features are used? What is the Classification strategy? Situation: Input Image: Passport photographs, web camera, movie clippings etc.Setting-up performance criteria is a part of the problem statement – Is it to improve

the speed or accuracy? – Is it hardware implementation or simulation study etc? What is the size of database?

Relevance: Application.Why have you selected this problem? What are the engineering challenges that are addressed in the problem?

Literature Survey: How similar problems have been solved? Put your work in the contemporary context.

Problem #2

State the Problem (PHYSICS/REALITY). Start from the broad area and narrow down to the specifics.

Engineering design is a trade-off between Performance and Cost.

What are the performance criteria? What are the goals? What are the costs involved?

NARROW DOWN.

State the various approaches available to solve the problem. Literature Survey.

Justify the particular approach you are going to use.

Give both the theoretical basis and the basis for selecting particular tools.

If you are good at coding (programming), nothing like writing your own code.

Methodology and Tools

Generally a software tool is available. Based on the problem proper software tool has to be used. Proper input has to be specified. The tool also generates graphs.

What is the difference between a Technician and an Engineer?

A Technician knows how to use the tools. An Engineer can DESIGN a system. An Engineer can solve a problem, meet the challenges of a new situation.

Master the tool, but know its pit falls –

Some designs of automobiles, aircraft, computers have been withdrawn from the market because of bad design. This situation arises due to improper use of tools.

Three examples of Pit Falls: a) The spectrum of a sine wave computed using the FFT showed the spectrum of an exponentially damped resonance. b) Pole-zero estimation was made while the input signal that was made-up of only poles. c)Phase response showed a large range while theoretically it has to be within 2.

WARNING: Understand clearly the Physics of the problem and the limitations of the tool.

52M.S.Ramaiah School of Advanced Studies

Collecting the Results

Validate using simplified models. Solve it analytically. Estimate the expected results and compare them with those generated by the tools. Then apply to a complex situation. Replicate an earlier study.

How are you going to test the results?

Generate test cases like a test dose of an injection for possible allergic reaction.

Validate the results – Cross check the results to ascertain that the tools are being used properly, check if appropriate inputs have been given - in millimeter or meter, Temperature in Degree F or C, proper polarity ( + or -) etc.

Run the Experiment for Repeatability, Consistency. One Single Run is no experiment. No conclusion can be drawn.

Collect the Results in a systematic manner. Some of the experiments may be time consuming. Proper planning is required.

Presentation of Results

How to present the results? Prepare a menu card. Serve item by item.

The presentation must cover the following:

1 Tools or equipments used. Model No., Version No. , Manufacturer or Developer.

Actual set-up. Additional details can be given in Appendix.

2 Testing of the tool on a smaller scale before the actual presentation of the results or

Calibration of the instruments used to make the measurements.

3 Testing on data where results are predictable or replication - for validation.

4 Scope of the experiments regarding the range of the input parameters and what are the output parameters that are being measured.

5 Present one experiment at a time with a clear objective for the experiment. Present the results and discuss the main findings. Use Tables, Graphs etc for proper illustration. Use proper scale and legend for the Graphs.

6 Show the link between one experiment and another. Present the results in a graded manner.

Conclusions and RecommendationsConclusions are convictions based on (experimental) evidence.

Results are measurements. What you infer from the results are the conclusions.

Exmp: Data on Rain fall Vs month of the year.

Conclusion: Usually there is no rain fall in Bangalore during the month of March.

Recommendations: Suggested action. Do’s and Don’ts.

Exmp: Conclusion: Delayed Submission of Assignment.

Recommendation: Deduction of marks.

List the Conclusions. For each item in the list provide the supporting evidence by referring to the Figures or Tables in the main body of the report.

Problem Formulation: begins with reality or Physics of the process - Modeling (theory).

Experiments are conducted using the model. Why? To deal with a wide range of input parameters, situations etc. Working with real systems is time consuming, expensive.

Results are generated using simulation tools or experimental setups.

Conclusions take us back to the reality or physics of a process.

General Hints

Whole to Part: Going from broad area or overview into details is a better approach. Master Plan to fine details. (Four walls and a roof; later interiors)

Do the work in several rounds. First round: Assume that you are preparing one page assignment to be submitted within one day. Propose a tentative title, write a crude report. Second round add some more details etc.

Look for information sources. Prioritize: Text Books, Journals (review articles) and Web browsing. Write down the reference immediately. Be FOCUSSED while browsing. Don’t go too deep during the first round of reading. Don’t try to understand all aspects. Just establish links between the problem and the sources.

Several rounds of light reading is better than one round of deep reading.

Categorize the reading material: Definition, Concept, Illustration, Formula, Details, Case Study etc. Xerox parts and build-up a crude report. Then write it in your own words.

Honesty is the best policy.

You cannot write a good report / paper unless you have something to say.

First decide what is that you want to say. Then say it boldly, clearly and briefly.

Technical writing is a boring job. Doing an experiment or computation or observing the sky is more exciting. (They involve new tasks!) But technical reporting is an equally important job. Hence it has to be done properly. It does not necessarily mean we have to spend more time.

PhilosophyPhilosophy

Poor technical writing makes one suspect about the care taken in your

technical work itself.

And they are wholly inexplicable on any other view.”Notice the confident summary from a Master. Also notice the word “wholly” in the last sentence: How precise and guarded he is!

I by no means expect to convince experienced naturalists whose minds are stocked with multiple of facts all viewed, during a long course of years, from a point of view directly opposite of mine. It is easy to hide our ignorance under such expressions as the ‘plan of creation’ ‘unity of design,’ &c., and to think that we give an explanation when we only re-state a fact.”Feel the pressure and pain under which he is writing. Also notice how he has used the word “stocked”. (Is it complimentary?) How clearly he points out the mistake of other naturalists.

Dark energy: The cosmological challenge of the millennium

Authors:

Abstract: Recent cosmological observations suggest that nearly seventy per cent of the energy density in the universe is unclustered and has negative pressure. Several conceptual issues related to the modelling of this component (‘dark energy’), which is driving an accelerated expansion of the universe, are reviewed with special emphasis on the cosmological constant as the possible choice for the dark energy.

Monsoon prediction – Why yet another failure?Authors:

Abstract: The country experienced a deficit of 13% in the summer monsoon of 2004. As in 2002, this deficit was not predicted either by the operational empirical models at India Meteorological Department (IMD) or by the dynamical models at national and international centres. Our analysis of the predictions generated by the operational models at IMD from 1932 onwards suggests that the forecast skill has not improved over the seven decades despite continued changes in the operational models. Clearly, new approaches need to be explored with empirical models. The simulation of year-to-year variation of the monsoon is still a challenging problem for models of the atmosphere as well as the coupled ocean–atmosphere system. We expect dynamical models to generate better prediction only after this problem is successfully addressed.

Cratering and spall simulation of Pokhran-1 event with three-dimensional transient finite element analysis Abstract: Three-dimensional transient numerical simulation of coupled gas cavity and geological medium problem resulting from underground nuclear explosion events is complex due to the gas cavity growth, resulting into the large deformations and large strains of the geological medium and shock-induced high strain-rate dependence of the response. However, it is important to establish the effects of local inelastic and nonlinear behaviour due to crushing and cracking of the geological medium, on the shock-waves near the source and the seismic signals beyond the elastic radius. This study also helps simulate the shock-wave reflection effects from the free surface near the ground zero, mound growth, spall near the free surface and the subsequent free fall of the mound due to gravity effect resulting in crater formation. The impacting spalled rock layers give rise to secondary seismic signals in addition to the primary signals that are observed in the near field which in turn are known to influence the far-field seismic signals. The present article describes the capabilities of a three-dimensional transient finite element code, SHOCK-3D, for the shorttime cavity growth, shock-wave propagation, mound growth and its free fall along with the settlement of the mound observed after a longer duration for the composite layer medium. The code predictions are benchmarked for the near-source experimental observations of the first Indian nuclear explosion event of 1974, carried out at the Pokhran test site.

Women, Science and the X-Chromosome

International Women’s Day is celebrated every year on 8th March. The day has been institutionalized by the United Nations, although various dates in March have been previously associated with the struggle for equality of women. The women’s rights movement has its origins in the struggle to vote by women in the United States in the latter half of the 19th century, most dramatically highlighted by the 1873 trial of Susan B. Anthony in the United States for illegal voting, Women’s Day appears to have firmly rooted beginnings in Europe. March 8 presumably commemorates the famous strike in St. Petersburg organized by Russian women in 1917, a spontaneous uprising for ‘bread and peace’ in a Russia ravaged by war and ripe for revolution. Today, Women’s Day is used to focus attention on the many issues that ensure that women continue to live in an unequal world. This year, I received an invitation ……… P. Balaram
