ABSTRACT

In the first paragraph the student has to make introductory remarks on

the significance of the title given to the project. The title has to be unique

and cannot be copied as it is from the journal/conference publication. Theimportance of the project with respect to practical application also has to be

written clearly. The first paragraph should not be more than eight lines.

The conventional methods used to achieve the objectives of the title

that have been used and discussed in the literature have to be briefly

mentioned in the second paragraph. The method adopted by the student in

the project has to be explained where the advantages and disadvantages

should be weighed corresponding to the method under consideration. The

second paragraph should not exceed more than ten lines.

The third paragraph must emphasize on the mathematical modeling

corresponding to the methods discussed in the second paragraph. The

explanation should be crisp and the paragraph can have a maximum of ten

lines.

Fourth paragraph must accentuate on the problem outline and theobjective of the project work. The problem outline should be vividly discussed

which in turn must deliver the objective. This can be written in about five to

eight lines.

Here the proposed work/method with its methodology has to be

discussed in detail so that the reader can easily understand the nuances of the

project work undertaken by the student. The fifth paragraph can be written in

ten lines.

The last paragraph must be used to discuss the results and conclusions

drawn from the project. The student must very carefully write this paragraph

as this decides the extent to which the project has been completed. A

maximum of four lines can be used for this elucidating the results.

Introduction

The undergraduate engineering education at MGIT is embodied withthree facets, namely, primary understanding, detailed study and application.

Students are given basic education, provided detailed background in onechosen area of engineering, and finally shown how to apply these concepts.With the above spirit, the Bachelor of Technology Project plays an importantrole of synthesizing the various elements of undergraduate education.

Students are posed with one comprehensive real-life engineering problemthat involves 3-4 facets of the engineering specialization chosen by thestudents. In about 4 months, all students of the graduating class work inteams and arrive at different proposals as engineering solutions to the problem

posed to them. The methods and skills applied shall be based on theengineering education acquired by them during the Bachelor of Technology

Program at MGIT.

This team approach of problem solving on a competitive platform isintended to prepare the students for addressing an engineering problem in aturnkey sense, as is the case in the engineering profession.

1.1 Purpose of This Document This document, henceforth referred to as the Manual, presents the

general and specific requirements for the preparation of the Bachelor of

Technology Project Report. It presents guidelines for arrangement of thecontents of the report. Detailed accounts on possible styles, structures andpresentations of technical reports are available in literature. The purpose ofthis Manual is to maintain uniformity in the project reports submitted byindividual students of the electrical department.

1.2 Project Report SubmissionFor the purposes of examination and record, three copies of the report

are required to be submitted to the guide, department library. Also, thestudents are required to submit to the Central Library of the Institute, softcopies of the Bachelor of Technology Project Report in PDF format. Anindividual copy of the report has to be retained with every student of theproject batch. The Project Supervisors are required to ensure that the

specifications and guidelines as prescribed in this Manual are adhered to bythe students while preparing the Bachelor of Technology Project Report.

Chapter 2

Guidelines for Arrangement of Contents

The Bachelor of Technology Project Report consists of three parts, namely(a) preliminary pages, (b) main body, and (c) appendices. Parts (a) and (b) aboveare mandatory in all reports. In some Bachelor of Technology Project Reports,where vast amount of raw data is generated or used, the main body is keptbrief by including only the representative and critical data derived from the rawdata. However, the detailed account of the raw data can be included in the part(c) for purposes of reference and record.

2.1 Preliminary Pages This manual has all its preliminary pages in the formats in which

preliminary pages are required in the Bachelor of Technology Project Report.

2.1.1 Title Page The first page of the report is the Title Page. It contains the title of the

report at the top, followed by the partial fulfillment clause, the degree for whichthe report is submitted, the authors with their role numbers (placed in theorder of the role numbers), the Institute logo, the name of department and

Institute to which it is submitted, and the month and year of submission.

2.1.2 Certificate PageA certification from the Project Supervisors, stating that the contents of

the report are based on the work done by the students under their supervision,

constitutes the next page. A text of the same is shown on page iii of thisdocument.

2.1.3 Acknowledgments Page The authors of the report may include warm acknowledgments in

recognition of the support and help rendered by different persons and

organisations in the conduct of the project.

2.1.4 Table of ContentsFor the ease of readily reaching the different sections of the report, a

complete table of contents should be included indicating the sections and the

corresponding page numbers.

2.1.5 Abstract Page The second page of the report contains the abstract of the report in a

maximum of 250 words. The text should be in single spacing.

2.1.6 List of Tables and FiguresFor quick access to the tables referred to in the text, a list of tables and

figures is essential. These lists are made on separate pages and should followthe Table of Contents page.

2.1.7 List of Symbols The various symbols used in the body of the text are defined in detail on

the first instance of their occurrence. However, a separate list of the briefdefinitions of all symbols should be included for easy comprehension of thereport; should the symbol appear at a location far away from where it has beendefined first, this list will be a great help. Some symbols appearing in thismanual and their brief definitions are presented in the List of Symbols on pageviii. As shown, the English alphabet based symbols appear first and then theGreek alphabet based symbols.

2.2 Main Body

The author must provide the content of the Bachelor of TechnologyProject in the main body of the text. In general, it may contain the followingsections: (a) introduction of the subject matter of the project, (b) status of thework done in this areas - problems, and issues involved, (c) relevance,motivation and objectives of the present work, (d) detailed literature review of

the past work of relevant to the topic of project at hand, (e) formulation andtesting of the analytical model, (f) analysis and design of the system, (g)analysis, design and conduct of the experimental part of the study, if any,(h)analysis of the experimental and analytical data, (i) validation of the datagathered from analysis, design and experiments, (j) discussion of results, (k)concluding remarks, and (l) recommendations for future work, if applicable.

Any past work quoted in the report shall be properly cited. And, a list ofall references cited in the report shall be provided at the end of the main text ofthe report.

2.3 Appendices The appendices play an important role of record keeping of the valuable

data gathered for and during the project. The appendices may contain differenttypes of data, e.g., questionnaire and survey forms, raw experimental data, raw

analytical data, drawings, computer program listings, and detailed derivationsof certain expressions used in the main body of the report.

2.4 Closing Remarks This manual gives only basic requirements for preparing the project

reports. In addition to the points mentioned in this document, the reportshould be easy to read and pleasant in appearance. Several aspects of reportwriting, e.g., style of writing and presentation, are not discussed in thisdocument. Guidance may be obtained from standard literature on the subjectmatter of the report.

Specification for Report Format

In general, the reports submitted by the different students of the departmentmust bear a uniform style and format; even within a report, adopting anidentical style and format throughout the report, will lead to an easily readabledocument. The specifications mentioned in this chapter are mandatory in thepreparation of the report. The department shall not accept a report that doesnot adhere to these specifications.

3.1 Preparation of Manuscript The report shall be typeset on any electronic medium with uniform sized andspaced characters, lines and margins on every page. The font used shall be

“Bookman Old Style” for the entire text in the report, irrespective of whether

it appears in the text, figures, tables or appendices.

The report shall be free from typographical errors and handwritten correction. The “spell-check” facility available with the word processors should be utilizedfor this purpose. The use of tape as an adhesive is not permitted. Allphotographs shall be used after proper acknowledgement from the source ifthey are being directly used from existing literature.

The matter shall be printed on good quality white bond paper by laser printers. The pages shall not be printed back to back. Only single side printing is to be

done to avoid any confusion.

All copies of the report shall be clear, adequately dark and even. The resultsand important figures pertaining t the project should not be pixilated and mustbe printed in color so as avoid any ambiguity to the reader.

3.2 Sizes and Margins The finished size of the report shall be that of an A4 page, i.e.,

210mm×297mm (8.27 inches × 11.69 inches). The margins at the top, bottomand outside shall be 25mm (1 inch), while that in the inside shall be 32mm(1.27 inches). These limits are applicable for the entire report, including pageshaving tables and figures.

Any subheading placed near the bottom of the page, shall have at leasttwo lines of text following it oil that page; else, it must be started on the nextpage. The text in all tables and figures shall conform to the same requirementsas applicable to the running text.


15/23

3.3 Style of WritingAll text shall be cast in third person singular. The sentences shall be

kept in passive voice. Personal opinions, thoughts and feelings shall not beincluded in the report, however valid, important and correct they may be.

3.4 Page Numbering The report is printed on only one side. Beginning with the first page of

Chapter 1, all pages of the report including the appendices shall be numberedsequentially in Arabic numerals, e.g., 1, 2, 3, The pages preceding Chapter 1,which are referred to as the preliminary pages, shall be numbered in lower caseRoman numerals, e.g., i, ii, iii,…. In this regard, the title pages (the first twopages inside the front cover) is considered to be having number I and ii ; this

number is, however, not printed on the title pages.

All page numbers shall be placed in the lower outside corner of the pagein the footer area at the bottom the page; the number shall be right justified to

the available footer text area on the odd pages (right hand side pages) and left justified to the available footer text area on the even pages (left hand sidepages).

The font type for page number shall be same as that of the text in thewhole report, i.e., Bookman Old Style. The font size, however, shall be 10pt andin bold style.

3.5 Font, Line Spacing and Justification The font size and style to be used on the Title Page are different for

different line. The title of the report at the top of the page will be in 16pt, boldstyle. The partial fulfillment clause is in 12pt, regular style. The degree forwhich the report is submitted is in 12pt, bold capital style. The author name is

12pt, bold style with first letters in capitals, and their role numbers in 12pt,regular style. The name of department to which the report is submitted is in

12pt, bold style. The name of the institute to which it is submitted is in 12pt,bold capital style. And, the month and year of submission is in 12pt, regularstyle. The line spaces between the above items shall be adjusted for aestheticappeal.

The font size in the whole report is 12pt for all text in the preliminary,

main and appendices pages. Some text in the tables and the figures may havesmaller fonts, but not smaller than 8pt. However, the titles of the tables andfigures shall be in 12pt. The chapter title is in 16pt, bold style. The lineshowing the chapter number is in 14pt, regular style. First level sub-headingsare in 12pt, bold style with first letter capitals. The second level subheadingsare in 12pt, bold style, and the third level sub-headings in 12pt, bold style initalics. In the chapter titles, headings and sub-headings, where first letters arein capitals, words, such as “of”, "a", "an" and "the", are in lower case.


16/23

All text in the report shall be in 1.5 line spacing with each line 12ptthick. One blank line of 12pt size is provided after every paragraph. Before

every first heading, two blank lines are provided each of 12pt size and beforeevery first and second level sub-headings, one blank line of 12pt size. No space

shall be left between the headings & subheadings and the text that follows

them. Between the lines having the ruler under the chapter number andchapter title, one blank line is provided of 12pt size. The entire text shall bedouble justified to the width of the available textbox after removing themargins.

3.6 Equations, Tables and FiguresAll equations, tables and figures shall be prepared on electronic media.

Equations are embedded in the text at the appropriate locations. Equationsshall be placed with one tab from the left margin of the active text. Eachequation shall be assigned a number, which is placed in right end of the line inparentheses. For example:

Magnetic flux is produced in the windings when a current flows throughit. Since flux passes through, or links, all turns of the winding it is known asflux linkage ( ).

This can be derived as,

i R

N 2

(3.1)

where R is the total reluctance seen by the flux, N is the number of turnsin the winding and i is the current in the winding. Inductance is defined as therelationship between flux linkage and current.

(3.2)

The primary significance of flux linkage is that it induces a voltage e ,across the winding in question whenever it changes with time. This isdescribed by Faraday's Law

dt

d e

(3.3)

The polarity of the induced voltage is governed by Lenz's law.Substituting 3.2 into 3.1, and applying Faraday's Law,

Where, v = dx/dt is the velocity at which the inductance changes. The

first term is the transformer voltage. The second term is the back EMF andvaries with speed.

Tables are placed immediately following the paragraph in which their

reference is made. Between two consecutive tables or two consecutive figures,two single line spaces are provided (each of 12pt thickness). All tables bear anumber and a caption. The number and caption of a table precede a table. Nospace is provided between the table caption and the table itself. If there is not

much place in that page to accommodate the table, it must appear at the top ofthe next immediate page. Table 3.1 demonstrates this; the table lists theresults of the load test carried out on a BLDC motor.

The load test is carried out on an eddy current setup where the motorgets loaded as a result of the eddy currents setup from the fly-wheel that is

attached to the motor. The tabular column below shows the loads that are used

to load the motor and hence determine the efficiency of the motor.

Hand drawn figures are not acceptable. Just as the tables, figures also areplaced immediately following the paragraph in which their reference is made.

All figures shall bear a caption placed below the figure; there shall be a singleline space in between the figure and its caption. Please see Figures 3.1 and 3.2

for a demonstration of the same. Again, if there is not much place in that page

to accommodate the figure, they must appear at the top (or after a table there ifany) of the next immediate page.

Figure 3.1 Winding Design for 14-Pole 12-Slot motor

Figure 3.2 Operating Point of the Permanent Magnet

All equations, tables and figures are numbered chapter-wise in Arabic

numerals. They are numbered sequentially in the order of their firstappearance. Equations, tables and figures are referred as Eq. (3.1), Table 3.1and Figure 3.1, respectively. The figures should not be directly copy pastedfrom books or the internet. The student is expected to make us of tools likeMS Paint® or MS word® or MS PowerPoint® to draw the figures and MS Excel® to plot graphs.

Plagiarized figures or block diagrams and graphs or plots will not beentertained. The guides are requested to check for such discrepancies.

3.7 SymbolsAll symbols used in the text are listed alphabetically and defined in the

List of Symbols in the preliminary pages of the report. First, all the uppercasesymbols are listed then lowercase symbols, and finally the Greek symbols (in

the Greek alphabetical order).

3.8 References All formal literature used in the project work is referred to at the

appropriate locations in the text. The standard IEEE format must be used tocite the references.

When there are two authors, the last name of the first author is followed

by an "and" and the last name of the second author; this is then followed by acomma and the year of publication When the number of authors is more thantwo, the citation has the last name the first author followed by "et al”, a commaand the year of publication [e.g., Arlekar et al, 1997].

However, the entire list of authors is provided in the reference includedin the list of References. All references are in single spacing with second andsubsequent lines indented forward by 5mm. Only those references cited in textare included in the list of references.

3.9 AppendicesEach appendix starts on a fresh page. Each appendix is identified by

capital letters of English alphabet in the sequence of their appearance. The

sub-sections in the appendices shall be numbered with the first letter beingthat of the English alphabet corresponding to that appendix. Please see

Appendix A for examples.All specifications applicable for the main text of the report are equallyapplicable to the appendices too. When appendices are making the report

voluminous, they may be printed in reduced font size to limit the size of thereport; in such cases, the font size is not smaller than 8pt.

3.10 Printing and Binding The prescribed number copies as mentioned before of the report are to be

submitted in the hard bound form. The paper quality is white bond paper, atleast of 80g/m2 quality. The front cover of the bound volume bears the samematerial as the Title Page of the report. The cover of the report is in dark blue

colour. On the cover of the report along its thickness, the title of the project isto be clearly written. If the title is too lengthy then the size may be adjusted tofit the mid-rib of the book.

Chapter 4

Summary and Conclusions

This is the last chapter of the report. This chapter is usually very brief, with

precise statements that summarizes and conclude the report.

4.1 Summary This section summarizes the project. It has the objective of the study

undertaken, the methodology adopted and the work accomplished. The aboveitems are very concisely described here; details are not provided.

4.2 Concluding RemarksSince Bachelor of Technology Projects hold the philosophy of synthesis of

knowledge acquired during the undergraduate program, the work conductedfor the project is not, expected to have “research type” conclusions that may

have significant bearing on the state-of-the-art or of-practice. However,concluding remarks on the salient observations made from the project work arerecapitulated in this section. If there are specific recommendations for future

work in the subject matter discussed, the same may be made here.
