How the planning concept of “Microdistrict” (Xiaoqu）shaped the Chinese contemporary living ideologies: Documentation and Understanding of Space-People Relationship

Have microdistricts changed Chinese people’s living ideologies? The appearance, spatial relationships and community organizations of Chinese Microdistrict have changed dramatically over the decades since the 1950s when the Soviets first introduced this concept. Meanwhile, the rapid urbanization and commercialization of the real estate market...

SunBox: Screen-To-camera communication with ambient light

A recent development in wireless communication is the use of optical shutters and smartphone cameras to create optical links solely from ambient light. At the transmitter, a liquid crystal display (LCD) modulates ambient light by changing its level of transparency. At the receiver, a smartphone camera decodes the optical pattern. This LCD-To...

Designing an optical link between a micro-display and a smartphone camera

The popularity of various wireless communication applications is crowding the radio spectrum. As an alternative medium, the visible light spectrum is be- ing exploited. Camera-based visible light communication systems are gaining much attention due to the widespread use of smartphones equipped with small embedded cameras. Screens (e.g., liquid...

The negative effect of carbohydrates on protein degradation in the acid-phase of anaerobic digestion of protein-rich wastewater: a microbial composition study

Anaerobic digestion (AD) is a promising technology to process protein-rich wastewater. However, incomplete protein degradation during the acidification of organic matter is frequently observed when carbohydrates are present. Literature reports little information to explain the mechanisms behind this phenomenon. This MSc study investigated the...

Influence of particle size distribution on anaerobic degradation of phenol and analysis of methanogenic microbial community

Sludge morphology considerably affects the mechanism underlying microbial anaerobic degradation of phenol. Here, we assessed the phenol degradation rate, specific methanogenic activity, electron transport activity, coenzyme F₄₂₀ concentration, and microbial community structure of five phenol-degrading sludge of varying particle...

SmartVLC: Co-Designing Smart Lighting and Communication for Visible Light Networks

Visible Light Communication (VLC) based on LEDs has been a hot topic investigated for over a decade. However, most of the research efforts assume the intensity of LED light is constant. This hypothesis is not true when Smart Lighting is introduced to VLC, which requires LEDs to adapt their brightness based on the intensity of natural ambient...

An interactive model among potential human risk factors: 331 cases of coal mine roof accidents in China

In order to explore optimal strategies for managing potential human risk factors, this paper developed an interactive model among potential human risk factors based on the development processes of accidents. This model was divided into four stages, i.e., risk latency stage, risk accumulation stage, risk explosion stage and risk residue stage....
