TeamsTeams

• Teams have been formed, with 2-3 members in each group• Each group should have a team leader who schedules and

coordinates group events and submits your work to the hand-in system.

• Each team will be provided with a DSP/FPGA board. You can use your personal computer or a Lab machine to manipulate the boards, as long as the required software is installed.

• Following is the grading criteria with a total of 100 points for any projects. But different projects may carry different weights in your final grade.

– Project report: 20% – Detailed source code comments and README: 20%– Oral discussion: 60%

• Typically, all members in a team will get the same grade for a project, unless the team leader or other members report that someone contributes little to the project and he/she should get only a certain percentage (e.g., 90%) of the team’s grade.


Some Suggestions for Your SuccessSome Suggestions for Your Success

• Start as early as you can!

• Do good project management (e.g., risk anticipation)– http://en.wikipedia.org/wiki/Project_management

• Do efficient teamwork

• Follow guidelines to manage your source code– C: http://www.jetcafe.org/jim/c-style.html– HDL: http://www.altera.com/literature/hb/qts/qts_qii51007.pdf

• Use automatic documentation tool:– http://en.wikipedia.org/wiki/Comparison_of_documentation_generators

Thesis ProposalThesis Proposal

• Use of PLC as a fieldbus– Modbus, Profibus,… tunneling

– Standard? PRIME, G3…

• Long Range wireless communication– Smart metering

– SDR implementation

• Mesh wireless networking (IEEE802.11s, BTMesh…)

• POSSIBLE SOSTITUTION OF THE EXAM

Thesis ProposalThesis Proposal

• Master thesis in ABB– ABB R&D in Sweden is looking for skilled guys who want to apply for

Master thesis related to real-time wireless communication for industrial automation. The students will be working with Software Defined Radios to implement some new PHY and MAC functionalities since we have no possibility to change/adapt traditional HW. So the student/students will work with areas such as signal processing, wireless communication, and programming in Matlab and C/C++. It is a plus if they have knowledge about real-time systems, electronics and automation.

• POSSIBLE SOSTITUTION OF THE EXAM
