2

• (MIT)This subject involves individual the basic process of science research beginning with defining the problem, researching background information, understanding the various types of evidence,

• becoming familiar with various types of inferential-statistics multivariate-statistics experimental-design, sampling techniques statistical package etc,

• analysing, representing information visually, and presenting of the argument.

3

• (MIS) Students will study the process of scientific research beginning with the definition of a problem,

• researching the background information, understanding the various types of evidence,

• becoming familiar with various types of inferential statistics

• multivariate statistics, experimental design, sampling techniques,

• statistic package etc, analysing, representing information visually

• and finally the presentation of the argument.

4

• Research: studious enquiry or examination, especially critical and exhaustive investigation or experimentation having, for its aim the discovery of new facts and their correct interpretation, the revision of accepted conclusions, theories or laws in the light of newly discovered facts or the practical application of such new and revised conclusions, theories and laws. (Webster)

Finding a Topic

1) MIT thesis 12 credits, MIS special problem 3 credits .

2) General area of interest e.g. cloud computing, Internet security, encription, speech to text/text to speech, image processing

3) Narrow down to something doable, but not trivial – current knowledge, literature, experts

6

5) Start planning - what is the current situation - what techniques to use, equipment – timing.

6) Measure of success.

Not a once through process.

Many feedback loops, particularly steps 4) – 6).

The most important question when choosing an area –

Are YOU interested in it?

7

Selected Area

• What do I already know?• What has been happening in the area

recently?• What are potential research problems?• Which one do I think I want to work on?• Then:• STOP• Sleep on it

Bertrand Russell (philosopher):

• I have found . . . That if I have to write upon some rather difficult topic . . . The best plan is to think about it with very great intensity – the greatest intensity of which I am capable – for a few hours or days and at the end of that time give orders, so to speak, that the work is to proceed underground.

• After some months I return consciously to the topic and find that the work has already been done.

9

• Before I discovered this technique, I used to spend the intervening months worrying because I was not making any progress;

• I arrived at the solution non the sooner for this worry, and the intervening months were wasted , whereas now I can devote them to other pursuits.

10

• Does not avoid hard work and thinking but is more efficient. Processing in the background.

•

• Think you have your topic?

• Know what you want to achieve and where you are starting from?

• Objectives and scope

• Now start planning the route to get there. How do I get from the present situation to my goal?

• Methodology

11

• Will require thinking about tools to use, mathematics for proofs of theory. Data simulation, applications to real data.

• Think about time.

• How long will it take?

• The scope may need revising as this develops.

• Benefits of the work

• How will my new knowledge help society? How will it be used?

12

• Ready for thesis topic proposal?

• 12 credits coursework, GPA at least 3.0, passed comprehensive exam. Enrol in 3 credits.

13

Preparing a Thesis Proposal• In preparing a thesis proposal students

should cover the topics covered in the sections below

• The thesis proposal should contain:• Thesis title (Very important for the

Graduate College – difficult to change once approved.)

• The background and importance of the problem (Specify the problem, the importance of the problem and why it is necessary to do research to solve it.)

• (Show you know what has been done before and the importance of the work.)

14

• The objectives (State the objectives clearly. If previous knowledge is necessary to do the research state clearly the assumptions that will be used in the research.)

15

1. (Development of an open learning system to support the training for Khmer localisation)

• Proposal version 1• The main objectives of the study as follows:• To analyze and design a suitable

instructional pattern to solve the current problems of Khmer Localization Training.

• To develop and test an Open Learning Environment (OLE) based on open source web application to support Khmer Localization training.

16

• To assess whether the use of an open source web application can provide the learners with an additional learning that they can learn by their own.

• To assess the level of system’s contribution that will be used by the instructors in order to supports the learners.

17

• Final report• The main objectives of the study are as

follows:• To develop an Open Learning System

(OLS) which is fully supported the use of Khmer Unicode and based on open source software (OSS).

• To develop online learning content which have to conform to the Sharable Content Object Reference Model (SCORM).

18

• 2. Business Intelligence Using Incremental Learning Parallel Fuzzy Ant Colony Optimization with Factor Analysis

• 3. Intelligent system for diagnosis and recording of breast cancer patients: case study at Siriraj Hospital.

19

• The scope of the research (Specify the basic research area, the main research topic and how long you have been studying.)

20

• Methodology ( Specify your plans for doing your research, the necessary steps in the research, the tools needed to do the research, how you are going to collect your data, how you will change the results)

• This is where you outline what you are going to do, briefly. We want to know what hardware and software you plan to use, because it may be expensive, e.g. time on Big Blue, an expensive software package.

21

• Where will your data come from? • Collect raw data yourself, simulate data, use

data collected anyway by an organisation, (gov. dept., hospital, insurance scheme, bank, retailer) use publicly available data sets – some available on the Internet.

• Timing – when are you going to do what. A timetable should be provided showing your plans. Remember it takes time to write up your thesis report. Writing up should start once your title has been approved.

22

• Usefulness of the research (Specify clearly what the results to come out of the research will be. Show how the outcomes of the research will be used to solve the problem.)

• What will the results of your research be used for?

• How will they advance knowledge in the field?

• References (List the books and journal articles that will be used in the research in the format given in the Graduate College handbook.)

23

• This will be all documents you have referenced in your thesis proposal and not others.

• A detailed discussion of referencing later.• Other details. In addition list any relevant

information needed depending on the postgraduate course.

• Form GC 53 says not more than 5 pages.

24

Conquering the literature

• How do I know what other people have done/are doing in a particular field?

• Read and understand the literature.

•

• Finding the literature.

• Understanding what you are looking for.

• Where you can find it.
