Volatile organic compounds (VOCs) emitted from building and vehicle cabin materials seriously affect indoor in-cabin air quality, as well human health. Previous studies revealed that some VOCs could react with ozone to the concentration levels of environment, but seldom refers materials. In this study, we performed experimental investigation for two kinds (car carpet, sealing strip) one furnitu...

Abstract Since the Antarctic scientific research device has been operating in Antarctica for a long time, power generation cabin needs to continuously provide heat so that its equipment can work within suitable temperature range. In view of complexity environment and high cost equipment, it is difficult test evaluate, which be well solved by numerical simulation test. The thermodynamic mechanis...

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...

Air distribution systems in commercial aircraft cabins are important for providing a healthy and comfortable environment for passengers and crew. The mixing air distribution systems used in existing aircraft cabins create a uniform air temperature distribution and dilute contaminants in the cabins. The mixing air distribution systems could spread infectious airborne diseases. To improve the air...

In this paper, a performance analysis on the estimation of so-called observation filter for Virtual Microphone Technique (VMT) in realistic automotive environment is presented. A comparison between adaptive and fixed methods, namely Least Mean Square (LMS) Minimum Error (MMSE), respectively, was carried on. Two different experimental setups were implemented popular B-segment car. Eight micropho...

In this study, effect of adding in SiO2 nanoparticle in base fluid (water) in car radiator is investigated experimentally. Radiators are compact heat exchangers that optimized and evaluated by considering different working conditions. Car\'s cooling system, plays an important role in vehicle\'s performance, consists of two main parts, known as radiator and fan. Radiators are compact heat exchan...
