Energy-efficient Spike Encoding for ECG Arrhythmia Classification

Cardiovascular diseases (CVDs) are the top cause of death worldwide, and their diagnosis can be quickly and painlessly achieved through Electrocardiogram (ECG). The diagnosis of electrocardiogram has gradually evolved from manual diagnosis by doctors to one that can be realized using Artificial Intelligence (AI). Early AI still required manual...

Exploring the Relationships of Language Pattern, Math Anxiety, Self-esteem, and Curiosity

Math Anxiety (MA) is some of the most notable mental health issues. The causes and development of MA are complex and inconclusive. This study highlighted that language patterns differ between people with high and low MA. Especially, the word categories positive emotion, insight, articles and linguistic dimensions. This study included two...

Correcting Global Elevation Models for Canopy and Infrastructure Using a Residual U-Net

Digital Surface Models (DSMs) are commonly employed to investigate topographical characteristics and processes; however, the presence of canopy and infrastructure in urban and forested areas can lead to height biases and inaccuracies. In this study, I aim to correct such biases by applying a deep learning approach known as Residual U-Net to...

Lens and Will: Sigurd Lewerentz’s way of travel

Throughout architectural history, outstanding architects have often been outstanding travelers. Sigurd Lewerentz, a legendary figure in Swedish modern architecture, is undoubtedly one of them. Lewerentz, who started his independent architectural practice in 1910 and died in 1975, lived during an exciting period that saw the emergence of many...

A robust control strategy for virtual coupling train platoons

This paper presents a train robust control method to optimize train operation based on the concept virtual coupling on train platoon. This approach is inspired by the recent development of platoon control for autonomous vehicles, and it is hoped that this platoon control can be applied to railway transportation. We use a decentralized model...

Tree Reconstruction from a Point Cloud using an L-system

Storing accurate models of complex geometries in a compact way has become an increasingly challenging issue, especially when dealing with large datasets. One of such datasets is Cobra-Groeninzicht's database of all trees in the Netherlands. In the gaming industry, a new technique is being used to generate tree models: the L-system. An L-system...

Low-level radar data based road user detection

In order to achieve redundancy and improve the robustness of an autonomous driving system, radar is a suitable choice for road user detection task in severe working conditions (e.g. darkness, bad weather). However, the real-time multi-class radar based road user detection algorithm is less explored compared with camera and LiDAR solutions. To...

Disclosing the military city: Bridging the border of MMC

Having lost its productivity, MMC became isolated from its context. Most of its links to neighbour and region broke as a result of its changing role. A series of dilemmas<br/>mainly exists as social conflicts and spatial conflicts appeared around the<br/>border as result. However, as the carrier of social conflict in MMC and witness of colonial...

Modelling information diffusion based on Epinion

Online social networks have been attracted considerable attentions and provided new channels for users to share and disseminate content, products, ideas and etc on the websites. With the advent of Internet, the user activities in online social networks can be easily tracked, which provide us with a extremely large scale of online data to study...

Van Raam BV is a specialized bicycle producer for people with disabilities. One of their products is Fun2Go, a side-by-side tandem tricycle, which was designed in 2005 and produced for 7 years. To make it more competitive, Van Raam wants to develop the next generation of Fun2Go. This project includs 4 phases: analysis, concept, embodiment and...

What Challenges Dutch Design in China? Towards a supportive tool for Dutch Designers and Design managers and their Chinese co-workers

The research focuses on the challenges that Dutch design companies have encountered in their practical work for the Chinese clients. Ten different respondents are interviewed for the research, including Dutch designers, a Dutch business director, a Chinese employee and so forth. The collected interview data contribute to explore the culture...

Performance and fairness enhancement in ZigBee networks

ZigBee is a robust wireless communication standard which is based on physical and MAC layer on IEEE 802.15.4. ZigBee is also critically limited by the low data rate standard when there are many source nodes in the network. How to fairly and efficiently access the network and delivery the packets should be considered as one of the crucial issues....
