Electrification of transportation is critical for a lowcarbon society. In particular, public vehicles (e.g., taxis) provide a crucial opportunity for electrification. Despite the benefits of eco-friendliness and energy efficiency, adoption of electric taxis faces several obstacles, including constrained driving range, long recharging duration, limited charging stations and low gas price, all of...

This study investigates taxi drivers’ multi-day cruising behaviours with GPS data collected in Shenzhen, China. By calculating the inter-daily variability of taxi drivers’ cruising behaviours, the multi-day cruising patterns are investigated. The impacts of learning feature and habitual feature on multiday cruising behaviours are determined. The results prove that there is variability among tax...

Motility responses triggered by changes in the electron transport system are collectively known as energy taxis. In Azospirillum brasilense, energy taxis was shown to be the principal form of locomotor control. In the present study, we have identified a novel chemoreceptor-like protein, named Tlp1, which serves as an energy taxis transducer. The Tlp1 protein is predicted to have an N-terminal p...

In this paper, we consider spatial predator-prey models with diffusion and prey-taxis. We investigate necessary conditions for pattern formation using a variety of non-linear functional responses, linear and non-linear predator death terms, linear and non-linear prey-taxis sensitivities, and logistic growth or growth with an Allee effect for the prey. We identify combinations of the above non-l...

Inhalable particulate pollution has adverse effects on human health. Many studies have been conducted to investigate levels and risks of exposure in public transit, but scant attention paid variations the among different positions inside cabin. Differences can be observed transit vehicles, like passenger density activities, which may lead differentiated between positions. Therefore, this study ...

Boundary layer induced noise, i.e. noise inside the aircraft resulting from the turbulent boundary layer enclosing the fuselage, is known to dominate air-cabin noise at cruise conditions. In this paper a method is described to design trim panels containing a large number of coupled tubes to effectively reduce this type of noise. The theory of viscothermal wave propagation in tubes, as presented...

Equations for studying flashover fire were studied experimentally in this paper. Experiments were carried out in a chamber inside a full-scale burning test hall of the joint project between The Hong Kong Polytechnic University and the University of Science and Technology of China. Three correlation equations on estimating the critical heat release rates for flashover were considered. The two-la...

This article reports on the wellness of selected cabin crew members at a South African airline. The aviation industry introduces a great amount of potential environmental stressors to cabin crew. The purpose of the research was to explore the wellbeing of cabin crew and the stressors related to their working environment. As primary safety officers on board an aircraft, cabin crew perform a vita...
