Master’s thesis administration

1) Today: general info 2) Schedule meeting with examiner and supervisor

Mail to supervisor and examiner Specify if you can’t meet in certain times of day

3) Bring application form ”Change of courses” to the meeting http://www.lith.liu.se/blanketter/changing_courses_master.pdf Register to the course TQET30 Master’s thesis Give signed application form to Britt Wirmark Spetsen floor 6

(SP6213) 4) Examiner registers thesis and students in x-sys 5) Log into x-sys (http://x-sys.itn.liu.se ) and upload thesis

description 6) Examiner assess thesis description (x-sys)

TQET30 Master’s Thesis

The Master thesis aims to demonstrate that the student Can use aquired knowledge and solve a problem in a

scientific framework in relation to the study program Has ability to use both verbal and written communication

in a professional manner Can assimilate the content of relevant literature and

relate thesis work to this Can critically review and discuss a thesis presented by

another student, both verbally and in writing Will demonstrate by own initiative to plan and execute

thesis work, but also be able to seek guidance and support from the supervisor, as needed

Thesis Project Planning Overview

TG1: Short thesis description and examiner approval (Now, x-sys) TG2: Planning report to examiner/supervisor (February) TG3: Half time report to examiner/supervisor (March) TG4: Final report to examiner/supervisor, as well as date for

thesis presentation (May) TG5: Thesis presentation (plus auscultations and opposition)

Presentations week 22 (May 31-June 4)

Phase 1:Planning

0 2-4 9-10 20 22

Phase 2:Literature study, problem definition, data collection

Fas 3:Analysis, recommendations, results, diskussion

Report writing (continuosly)

Thesis description

Authors and title Contacts Purpose of the thesis Background Problem formulation and solution method Related courses in your program Rough time plan

The initial description and information from the first meeting is used as input After the first meeting you should be able to write the thesis

description (i.e. be prepared for the first meeting) Think about what you write and always read it again after

finishing a text!

Planning report

Problem background and description Purpose and thesis objectives Scope (focus and delimitations) Tentative theoretical frameworks, example references

and method Headlines for the report Activities and time plan (Gantt schedule) Approx 5-10 pages

Half-time Report

Planning report + Literature study Detailed problem definition with well formulated notations Solution method alternatives System/model description Possibly

Data collection Initial results

Project Execution

Except the thesis description, the planning report and the half-time report you will continuosly report the progress of the thesis

Weekly report every Friday What you have done this week What you will be doing next week Relation to the time plan Problems that have occured and if/how they are solved If you need support from the supervisor

Typically communicated through email 5-10 rows is normally enough Some weeks a meeting might replace the email

Thesis in Mobile Telecommunication Group

Work flow: 1) Literature survey and documentation 2) Model or system development 3) Experiments 4) Vizualisation/documentation 5) Discussion and conclusions

The second step is typically a quantitative (mathematical) model, system prototype or algorithm Prototype/algorithm: ”it is possible to solve the problem by

implementing a system/algorithm this way”. Performance? Advantages/drawbacks compared to other designs?

Quantitative model, e.g. simulation: ”we can model the real system like this”. Does it behave like the real system? What happens with the system with certain input based on the output of the model?

Combination: evaluate system/algorithm using quantitative model

The Report

Professional report The meaning of every word you write is important and should be

considered Formal language You should never write what you have been doing in the thesis (e.g.

diary like), but instead what has been done in a professional and scientific context Bad: ”First we constructed a database with throughput measurements

and then we made a simulation model of the LTE network in Opnet” Better: ”A simulation model is used to evaluate the throughput of the LTE

network. The simulation model is developed using the Opnet simulation tool.”

Statements and facts should be supported (references, numerical results, proof…)

You are not allowed to copy one single word from a source unless you quote it Copy & paste material in the report (in any form) leads to abortion of the

project!

The Report

References Of course continuous referencing is required! Use IEEE style references (similar to Vancouver system)

http://wwwlib.murdoch.edu.au/find/citation/ieee.html References is an important factor for the quality of the report Put effort into finding good references

Relevant published articles Books Avoid web page references (sometimes it could be motivated to

reference to a company web page for example) No references to Wikipedia! (it is though good to read for quick

understanding and links to other references) Write proper references directly when you put it in the report Keep track of references continuously while you work

The Report

If you use MS Word: Use the format templates Spelling checks Automatic generation of table of contents Cross references to figures, tables etc

Figures and tables should be used (when relevant) Figure numbering and text below Table numbering and text above Always relate to figures and tables in the text No ”pictures”

Define ambigous expressions and words first time they are used

Write the full meaning of acronyms the first time they are used

Thesis Headlines Introduction

Background, purpose, objectives, method, scope, outline Theoretical framework (one or several chapters)

Literature study (background theory and what has been done so far within the field, e.g. ”UMTS positioning methods”, ”Network simulation”)

System/model description Description of the system or model that you have developed

Results/Analysis Experiments and results illustrated with diagrams and tables

Discussion Assumptions made in the experiments or model valid? Can the

results be generalized? Are there sevaral possible explanations to the results? How does it affect the problem being solved?

Conclusions Most important part of result/discussion (no summary) Recommendations and future work

Thesis Examples

E. Näslund (2004), ”Associating DAB and GPRS to provide an asymmetric communication network” Pictures overkill though

P. Sandberg (2007), ” Mobile Broadband – Service Experience and Evaluation”

Gives an idea of how a good single student thesis can look like Use for inspiration, not template or ”ground truth”
