4. 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)

5. 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

6. Thesis Project Planning Overview TG1 TG2 TG3 TG4 TG5 • 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) Fas 3:Analysis, recommendations, results, diskussion Phase 2:Literature study, problem definition, data collection Phase 1:Planning Report writing (continuosly) [weeks] 0 2-4 9-10 20 22

7. 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!

8. 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

9. 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

10. 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

11. 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

12. 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!

13. 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

14. 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

15. 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

16. 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” • Useful links • http://kts.itn.liu.se/exjobb?l=en&sc=true • www.bibl.liu.se • http://www.ep.liu.se/index.en.html • www.ieee.org
