Project work

Deeper study of a particular field of sensors/application. Give some experience in writing a research report. Possible project examples;

• Review of state of the art of certain sensors

• Experimental evaluation of a sensor setup

• Applications to industrial problems

Course examination:• Presentation of a related research paper• Writing of a research report of the project (6 pages or more

depending on format) and oral presentation of the results at a seminar

Project work (cont.)

Each project will be done by student groups of 2 students each. Any deviations from this groupsize will be exceptions and must be approved by examiner. They must be approved before project work starts.

Seminar with oral presentation of the project work + presentation of the related paper:

22 Oct 13.15-17 Room D415

Written report sent to course examiner email adress as a PDF file no later than:

1 Nov 23:59 ([email protected])

• The report/paper should have a similar type of structure as the example papers that are handed out from previous year

• It is very important that the report contain some references/review of earlier (related) work to your chosen project topic

• In addition to your own work, you need to present a paper at the seminar. Choose the subject of the paper so that it is related to your own work (paper choice should be approved by the examiner once projects have been chosen).

Project work (cont.)

• Fill out the paper which will circulate the class room after the lecture and decide who will be in each group by yourselves.

• I will email each group with project abstracts, each group then needs to send me their rank on each project (rank 1 – most interesting project, rank 2 – second most interesting project, etc). I will use this for deciding which group gets to do a certain project. It is possible that there will be more than 1 group working on the same project.

Grading criterions

• Adopted partly from master thesis grading

• May not need all criterions to be fulfilled to achieve a certain grade

Grading criterions (cont.)

Information RetrievalGrade 3Has compiled a satisfactory list of references.Knows which references are important and which are less important for theproject.Can summarize the most important references.Knows the contents of the remaining references in “abstract” form.Understands the problem and can formulate subproblems.Can relate the project to the references.Grade 4Can relate the references to each other and combine information from them andcome to conclusions.Can use the references to sharpen the project plan, i.e. decide to omit somestudies or concentrate on some subproblem.Grade 5Is able to criticize and find weak and strong parts in reference articles as wellas the own work.

ResultsGrade 3The result is acceptable, but can point at several things that,with a reasonable effort, would have improved it.Can identify and formulate significant strong and weak points in the result.Grade 4The result is good (i.e. matches well to the anticipated results in the, possiblyrevised, project plan) and can point at only a few things thatcould have been done better or that are missing.Can, with minor supervision, come to some conclusions on how the resultcould have been improved.Can, with minor supervision, formulate some future directions for the project.Grade 5The result is excellent and the supervisor can point at only very few minorimprovements which could have been done.The result is publishable in a scientific journal or at a conference.Can, without supervision, evaluate the result in relation to other work donein the field.

Presentation Grade 3

Presents the problem and proposed solution in a clear way.

Presents a clear analysis of the problem.

Can answer fundamental questions on the subject.

Grade 4

Presents the project in an attractive way with e.g. well chosen illustrations.

Can discuss different aspects of the problem.

Grade 5

An excellent presentation, which engages the audience and generates interested questions. All questions are answered in a relevant way.

Grading criterions (cont.)

ReportGrade 3The report is complete (i.e. with ”background”, ”methodology”,”results”, ”conclusion”, ”summary” etc.).All references, figures & tables are referred to in the text.Grade 4The report is, with significant supervision, well written. (”Well written” meansthat: The English is correct and the text flows smoothly. Figures are relevantand add value to the text. Similarly with tables. The result and conclusion isclearly stated.)Grade 5The report is, with minor supervision, very well written.The report is written such that it would be publishable, provided the result is good enough.

Fleet behavior can provide a norm in which an “unhealthy” bus can be detected as deviating from the norm. The RDM project investigates how this norm can be found and used on a fleet of vehicles to improve up-time management.
