Unlock Your World With Your Heartbeat: Evolution and Recent Trend of Electrocardiogram Biometrics

Biometric recognition provides automated security for identity recognition based on physiological or behavioural characteristics. It becomes one of the hottest topics in technologies nowadays as it offers an essential improvement over usernames and passwords. Emerging innovations to a mobile device, portable, wearable and other innovations are bringing biometrics to mainstream marketplaces. So far, various biometrics have been implemented in a real application for instance; face, speech, iris, signature and fingerprint. However, a security breach is one of the limitations of common biometrics. Recently, electrocardiogram (ECG) signal which is one of the most prominent biomedical signals for heart abnormality detection has been studied for the use of secure identity recognition. ECG has extremely discriminative characteristics in the biometric field and has recently received significant interest as a promising biometric trait. This innovation attracts intention among researchers owing to ECG signal is difficult to counterfeit through latent patterns as it is intrinsically originated from a critical heart activity. ECG signal analysis for biometric recognition can combine several steps, such as pre-processing, feature extraction, feature selection, feature transformation, and classification which is a very challenging task. Moreover, the selected success measures and proper structure of the ECG signal database play significant roles in biometric system analysis, considering that publicly available databases are essential to the research community to evaluate the performance of their proposed algorithms.  To date, ECG technology has emerged as a new viable alternative approach in a biometric scenario. In this talk, we highlight the recent advances in ECG biometric technology, its challenges and feasible future research opportunities.

On Orthogonal Circulant MDS Matrices

In 2019, Cauchois and Loidreau gave a necessary and sufficient condition for circulant maximum distance separable (MDS) matrices using q-polynomial rings. This work proves the non-existence of certain orthogonal circulant MDS matrices. The study also provides a necessary and sufficient condition for orthogonal θ-circulant matrices using q-polynomial rings. The orthogonal circulant MDS matrices over Galois rings are also discussed.

Experience Rating Using Bonus-Malus, With Applications in R

Bonus-malus system, which is used interchangeably as “no-fault discount”, “merit rating”, “experience rating” or “no-claim discount” in different countries, is based on penalizing insureds who are responsible for one or more claims by a premium surcharge, and awarding insureds with a premium discount if they do not have any claims. Insurers use bonus-malus systems for two main purposes; to encourage drivers to drive more carefully in a year without any claims, and to ensure insureds to pay premiums proportional to their risks based on claims experience. In this presentation, we relate the NCD system with a discrete time parameter Markov Chain, and show some applications of the Markov Chain model on the NCD system such as stationary distribution, convergence rate, premium evolution, and premium rating. We also show briefly the application of R on several insurance data.

Programming and Programming Languages Based on Mathematical Concepts 

In this talk, non-popular programming style and languages are introduced. They are based on mathematical concepts. These programming languages provide “declarative programming style” which is a different programming style from that of conventional programming languages such as C and other popular languages. For example, declarative programming languages do not provide iteration description such as “for” loop and “while” loop. Instead, they provide recursive processing to realize iteration. Furthermore, as declarative programming style and languages have strong theoretical background, they are suitable for theoretical analysis of programs and programming such as program verification and proof of correctness. Basic concepts and some examples of two declarative programming languages are provided in this talk.

STEGANOGRAPHY AND STEGANALYSIS FOR 3D MODELS 

Digital steganography is the embedding of information into carrier files, which could represent text, audio, images, video, or 3D models. Typical applications include copyright protection, copy control, protection against unauthorised alteration, and covert communications. Steganalysis, on the other hand, aims at the detection of hidden messages embedded into the carrier file. In this talk, we present our work on steganographic and steganalytic algorithms for 3D triangle meshes. At the end of the talk, we will also present our work on the related problem of embedding and extracting information from physical 3D printed objects, rather than digital ones. The focus of that part of the talk will be on the different requirements, challenges, and employed techniques, between these two settings of digital vs physical carrier.

BRIDGING TECHNOLOGY AND MATHEMATICS: USAGE OF GRAPHING CALCULATOR

In this era of fast technological advancement, keeping up with the latest innovations and inventions that technology can offer is essential to be relevant now and in the future. The graphing calculator provides millions of students worldwide as well as in Malaysia, with useful and exciting experiences, enhancing their mathematics learning with computer visualizations. Educators are now able to present mathematical ideas, concepts, and applications in both traditional as well as computer-generated numeral and graphical representations. Students who are engaged in their mathematical works are energized by four goals: success, curiosity, originality, and satisfying relationships. But the questions now are “How do we cultivate these drives in the students’ lives? How can we connect them?” To prepare students for life in today’s highly technical society, their mathematical knowledge must include and go beyond knowing the simple skills to solve more complex problems, and the use of graphing calculator-based instruction materials would be beneficial. One of the questions in the educational community is whether students will have a more meaningful learning experience by engaging themselves with mathematics and technology. In this presentation, the presenter will share what kind of work they find engaging and how to engage in work that stimulates students’ curiosity, permits them to express their creativity, and fosters relationships with others.

BITCOIN MINING AND ELECTRICITY CONSUMPTION

We propose a dynamic industry equilibrium model for Bitcoin electricity consumption in a general framework, including Bitcoin miners’ optimal entry and exit with technology innovation. By adopting average operating costs as an approximation to the true operating costs, we overcome the difficulty of strong path-dependency due to the interaction among entry, exit, and technology innovation. The model can capture both the upside and downside co-movements of miners’ computing power, electricity consumption, and mining revenue. Our model shows that the Bitcoin electricity consumption will not grow indefinitely, with the ratio of Bitcoin electricity consumption to the miners’ revenue fluctuating within a range. This work is joint with Steven Kou, Shuaijie Qian, and Ling Qin.

Workshop Synopsis:

Problem solving is crucial in mathematics and should be emphasised at all levels. Mathematical instructors, on the other hand, may not always be aware of how to meaningfully incorporate problem solving into the mathematics curriculum. Problem solving refers to mathematical assignments that may be used to increase students' mathematical learning and growth by posing intellectual difficulties. It is an essential process that is emphasised in the Malaysian Standard Curriculum for Secondary Schools' mathematics (KSSM) framework. In this workshop, participants would learn how to develop problem solving tasks that involves going through Polya’s four phases of solving a problem. Furthermore, the task developed would be solved with the assistance of the Classwiz scientific calculator. Not only will the learner solve the problem, but they will also validate the solutions with different methods.
