Multi resolution, high temporal fire monitoring and intensity mapping using Himawari-8 Advanced Himawari Imager data [3] This study is focused on utilising the multi-resolution and high frequency data from Advanced Himawari Imager to develop new algorithms for fire line mapping and fire intensity calculation. Two algorithms are proposed for fire line mapping and fire radiant energy: calculation...

In residential heat pump systems, the motivation for secondary loop systems is to allow for the use of flammable or toxic refrigerants with lower global warming potentials than the currently employed HFC refrigerants. The addition of radiant panels as integral building components (embedded in concrete at construction or attached to the underside of wood flooring) is becoming more common. Combin...

Soot concentration measurements in ethylene-O2/CO2 diffusion flames (fuel Re 120) encompassing oxidizer oxygen mole fractions (oxygen index, OI) of 35% to 90% were employed validate a methodology for modeling soot production. A skeletal 10-step reaction mechanism and the nucleation parameter (Cα) Moss-Brookes model as function OI provided adequate agreement with measurements. Cross-validation b...

Patient warming significantly decreases the risk of surgical site infection. Recently there have been concerns that forced air warming may interfere with unidirectional airflow, potentially posing an increased risk of infection. Our null hypothesis was that forced air and radiant warming devices do not increase the temperature and the number of particles over the surgical site when compared wit...

The efficacy of a Gamgee-lined hat in reducing the rate of fall in rectal temperature of infants during the first 30 minutes of life was studied. The trial, which included 211 infants, was randomised, prospective, and controlled. One hundred and seven infants were exposed to overhead radiantheaters. Of these, only 30 had normal deliveries, so the analysis was confined to the infants who were no...

Observing Earth’s radiant energy budget from space is critical to improving our understanding of Earth’s climate system. The Earth Radiation Budget Experiment (ERBE) (Barkstrom 1984; Barkstrom and Smith 1986) was the first initiative to provide simultaneous observations of Earth’s radiant energy with identical instruments flying aboard separate satellites. The design of the ERBE instrument was ...

We present a closed-form expression for the irradiance at a point on a surface due to an arbitrary polygonal Lambertian luminaire with linearly-varying radiant exitance. The solution consists of elementary functions and a single wellbehaved special function that can be either approximated directly or computed exactly in terms of classical special functions such as Clausen’s integral or the clos...

This study is focused on investigating the effectiveness of low heat accumulation asphalt mixture and its impact on the urban heat environment. Infrared radiation experiments showed that the temperature of the asphalt mixture decreased with the increase in far-infrared radiant material. The results also revealed that, compared to asphalt with 0% far-infrared radiant content, the asphalt materia...

Accuracy is an important measure of system performance and remains a challenge in 3D range gated reconstruction despite the advancement in laser and sensor technology. The weighted average model that is commonly used for range estimation is heavily influenced by the intensity variation due to various factors. Accuracy improvement in term of range estimation is therefore important to fully optim...

Background: Male reproductive disorders that are of interest from an environmental point of view include sexual dysfunction, infertility, cryptorchidism, hypospadias and testicular cancer. Several reports suggest declining sperm counts and increase of these reproductive disorders in some areas during some time periods past 50 years. Materials and Methods: Except for testicular cancer this evide...
