Mid-term PhD seminar
Today
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
Today
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
Tomorrow (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.

Biography:
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.

Final presentation of the course IT in Society
Tomorrow (13 Dec)

Half-time seminar
Friday 14 Dec
Fayiq Alghamdi: Computer Science Teachers Perspective on their Educational Epistemology - A case study in Saudi Arabia
Location: ITC 2446, Time: 13:00

In this halftime seminar, Alghamdi will present and discuss his work concerning how Computer Science teachers in Saudi Arabia have adapted changes in their educational epistemologies and how these changes appear in their teaching practice. The research describes the teachers’ perspective through their descriptions of their practices and experiences in schools. It is an investigation of the teachers’ educational epistemologies in teaching Computer Science in the Saudi Arabian culture, and how it is affected by external factors such as the new teaching competencies standard and teacher’s prizes. The external reviewer is Matti Tedre from University of Eastern Finland.
