Work performed by Computer Systems Engineering student Michael Shanta for his 3rd year project, supervised by Dr. Marina Cole and Dr. Siavash Esfahani in the School of Engineering, was written up in a paper that was recently accepted for presentation at the IEEE Sensors 2020 Conference.

For his 3rd year project Michael worked on developing machine learning techniques for an Electronic Nose in order to classify odours based on the sensor responses. The system aims to detect incontinence incidents, allowing alerts to be sent to relevant personnel from an IoT network via a cloud server.

We are pleased to report that members of the department's Theory and Foundations research theme have had 6 papers accepted to the 47th International Colloquium on Automata, Languages and Programming, the main European conference in Theoretical Computer Science and annual meeting of the European Association for Theoretical Computer Science. The papers are:

• On the central levels problem by Petr Gregor, Ondřej Mička and Torsten Mütze
• Matrices of optimal tree-depth and row-invariant parameterized algorithm for integer programming by Timothy Chan, Jacob Cooper, Martin Koutecký, Dan Král and Kristýna Pekárková
• The Complexity of Verifying Loop-free Programs as Differentially Private by Marco Gaboardi, Kobbi Nissim and David Purser
• Rational subsets of Baumslag-Solitar groups by Michaël Cadilhac, Dmitry Chistikov and Georg Zetzsche
• The Strahler number of a parity game by Laure Daviaud, Marcin Jurdzinski and K. S. Thejaswini
• On the power of ordering in linear arithmetic theories by Dmitry Chistikov and Christoph Haase

The Department of Computer Science and the Mathematics Institute jointly hosted, last Saturday 7th December, the Christmas Meeting for 2019 of the British Society for the History of Mathematics.

Our Departments have a long and strong association with the BSHM which has an established tradition of having its Christmas meeting in the Midlands. With about 50 participants, including some staff and students from both our Departments, there were 8 talks in the day ranging from figurate numbers in the 9th century, Islamic use of sexagesimal calculation for π and sine values in the 15th century, to fascinating details of Victorian data processing and the mathematical semantics of programming languages in more recent times.

There were plenty of interesting questions arising and lively discussions in the refreshment intervals. There was also a presentation of the BSHM Neumann Prize and the Society's AGM.

The day was widely acclaimed as enjoyable and successful. Our thanks are due to both Departments for their sponsorship, to the admin and technical support in Computer Science, and to the local organising work of Steve Russ and Adam Jones. Further information about the BSHM is at https://www.bshm.ac.uk/.
