DoCS seminar
Elena Di Lascio: Unobtrusive Monitoring of Students’ Affective State During Lectures Using Wearable Sensors
Location: ITC 2446, Time: 10:15

Modern wearable devices enable the continuous and unobtrusive monitoring of human physiological parameters, including heart rate and electrodermal activity. Thanks to the availability of these devices, researchers are now able to gather large amounts of data in real settings and use it to build more accurate affect models in naturalistic settings such as the home, work or school. In this talk, we present our work on using off-the-shelf wearable devices to unobtrusively monitor the affective state of students during lectures in terms of emotional engagement and classroom experience. Overall, our findings may inform the design of systems that allow students to self-monitor their engagement and act upon the obtained feedback. Teachers could profit of information about non-engaged students too to perform self-reflection and to devise and evaluate methods to (re-) engage students. Bio: Elena Di Lascio is a third year PhD student in Informatics at Università della Svizzera italiana (USI), Lugano, Switzerland. In the context of her PhD thesis, she is focusing on the unobtrusive inference of human well-being factors using smartphones and wearable devices. She received her Master degree in Communication and Information Technology Engineering at Università degli studi Roma Tre, Rome, in 2016. She worked on her Master's thesis "A Battery-free Indoor Localization System" at Uppsala University within the Uppsala Networked Objects (UNO) research group in 2016. She received her Bachelor degree in Electronic Engineering in 2013.

Pedagogic Lunch Seminar
Tomorrow (11 Dec)
Tobias Wrigstad: Mastery Learning with Achievements
Location: ITC 4308, Time: 12:15-14:00

You are kindly invited to the IT Pedagogic Lunch Seminar

Mastery Learning with Achievements

Place: ITC 4308
Time: 12.15-13.00, with extra time for discussion until 14.00.

You can find more and updated information in Medarbetarportalen.

If you’d like us to arrange lunch for you, you should sign up here at least two days before the seminar.


In this lunch seminar, I will talk about an attempt at implementing mastery learning on the 2nd year course on imperative and object-oriented programming. We adopt a design where the goals of producing a working program are the side-effects, the learning outcomes, in a very hands-on way: by having the students mine their programs, processes and designs for applications of achievements---core concepts in the course, and use these as evidence for demonstrating fulfilment of coarse goals in a back-and-forth with examiners.


I will talk about experiences of running a course like this for a number of years and lessons learned. In addition, Lars-Henrik Eriksson and Kiko Fernandez-Reyez will talk about experiences of running very different courses (Formal Semantics and Software

Design) using achievement-driven methods.

Mid-term PhD seminar
Wednesday 12 Dec
Malin Källén: Refactoring an HPC code base using object-oriented methodology -effects on maintainability and performance
Location: ITC 2446, Time: 13:15-15:00

My research connects high performance computing with software engineering. At my half-time seminar, I will address how the quest for performance can be approached without sacrificing the principles for constructing maintainable extensible software, and what compromises may be needed. At the end of the presentation, I will pose an open question to the audience to solicit input for future research. The external reviewer is Professor Serge Demeyer from the University of Antwerp, who is an expert in software reengineering and the evolution of object-oriented software systems.

DoCS/CSD seminar
Wednesday 12 Dec
Pavel Krcal, Lloyd's Register: Algorithmic Challenges in Safety Assessment of Technical Utilities
Location: ITC 2446, Time: 9:15-10:00

Operators across various industrial domains (e.g., aerospace, transportation, and nuclear energy), their customers and the general public share the utmost interest in safety. Maintaining and improving the safety of complex utilities requires mathematical modelling of a system under study and its potential failures. In an established approach, one uses formalisms combining probabilistic data for individual components and the structural information. The amount and type of dependencies between parts of the system that can be expressed in the model determine the complexity of the analysis. I will talk about the algorithmic challenges posed by the analysis of different formalisms. We start with the standard event tree/fault tree model and discuss its extensions by adding state information. Most examples and practical motivation of studied features come from the area of Nuclear Safety. I will present the current development and future directions in the safety assessment tool suite RiskSpectrum.

SysCon Seminar
Thursday 13 Dec
Dr. Ramon Delgado, University of Newcastle: Delay alignment in NR multi-point connections.
Location: ITC 2446, Time: 13:15

In a 5G new radio (NR) telecommunication system, low latency is crucial to enable new applications including wireless augmented and virtual reality, haptic feedback, and mobile industrial robot control. To meet with the requirements of these applications, an NR system will operate at millimetre wave (mmW) carrier frequencies. At these frequencies, radio shadowing conditions are severe and large moving objects may further deteriorate the radio transmission paths. This can be compensated with the use of multi-point transmission, where multiple base stations communicate simultaneously with one user equipment. To ensure the success of multi-point transmissions, synchronised arrival of originally adjacent data packets sent over these paths is essential. Therefore, a method to control the delays encountered by these data paths is needed in a multi-point connection.
This talk describes some challenges with delays in multi-point connections and how to handle them using mainly linear MIMO control techniques.

Ramon Delgado (homepage) received his professional title of Ingeniero Civil Electronico and M.Sc. degree in Electronic Engineering from Universidad Tecnica Federico Santa Maria, Chile. He received a Ph.D. degree in Electrical Engineering from the University of Newcastle, Australia, in 2014. He is currently a research academic at the University of Newcastle. In his current role, Dr. Delgado is primarily focused on the collaboration project between the University of Newcastle and the Swedish company Ericsson AB. His research areas include system identification, control, signal processing and optimisation.
