Congratulations to third-year Computer Science student Hengrui Zhang, who has had an abstract accepted at the British Conference of Undergraduate Research 2021 (BCUR 2021). Hengrui’s abstract, titled "Emotional Adjusted Chinese Sentiment Analysis", proposes a new and enhanced sentiment analysis model, SETCM, which combines the advantages of sentiment lexicon, emoji and neural computing technology. The proposed method overcomes the shortcomings of existing sentiment analysis on Chinese-language text. It is based on the work that Hengrui has completed as part of his third-year project, supervised by Dr Greg Watson.

Shen Wang and Professor Feng Hao from the Systems and Security theme at the Department of Computer Science and Ehsan Toreini from Durham University, have had the paper ‘Anti-Counterfeiting for Polymer Banknotes Based on Polymer Substrate Fingerprinting’, published in the journal IEEE Transactions on Information Forensics and Security, in which they propose a novel technique called Polymer Substrate Fingerprinting, which can identify each banknote’s own unique, unclonable fingerprint.

The researchers have found that every polymer banknote has a unique "fingerprint", which is caused by the inevitable imperfection in the physical manufacturing process, whereby the opacity coating, a critical step during the production of polymer notes, leaves an uneven coating layer with a random dispersion of impurities in the ink. This imperfection results in random translucent patterns when a polymer banknote is back-lit by a light source.

Congratulations to Samuel Ward, one of our third year Discrete Mathematics students, who has received a silver award as part of the Worshipful Company of Information Technologists’ (WCIT) Charity University IT Awards 2021. The awards, which were first held in 2015, seek to recognize outstanding undergraduate and postgraduate IT students within the UK. Applicants are judged based on their academic excellence, ability to overcome adversity, entrepreneurial skills, and contribution to charity or community.
