The Relationship

Heating films were prepared by using poly(methyl methacrylate) and polybutadiene composites containing graphite. The heating film was prepared by casting the as-made polymer composite on the PET film. Copper electrodes were attached to both ends of the as-prepared film, and the heating characteristics of the film were analyzed while applying the DC voltage. The electrical conductivity and the heating temperature of the heating films depended on the size, the structure, the content, and the dispersion characteristics of the graphite in the composite. The electrical resistance of the heating film was controlled to adjust the heating temperature of the film. The relationship between the physical/chemical structure and the heating characteristics of the composite film was studied by measuring the heating temperature as functions of film thickness and resistance by using an infrared thermal imaging camera. The lower the film resistance, the higher the heating temperature of the film. The surface temperature was uniform throughout the film.

The Relationship

Abstract Identifying severe bruising in livestock before slaughter is valuable because bruises are likely a source of pain for the animal that cannot be seen by visual inspection. This bruising may result in major trim losses because bruised tissue is considered unfit for human consumption. The objective of this study was to determine if bruising could be detected under the hide of live Holstein cull cows with infrared thermal imaging technology. A FLIR E8 thermal imaging camera was utilized to capture heat emission images pre-hide removal and post hide removal for 36 Holstein cull cows. Images were collected approximately 2 m from each cow and associated carcass images were examined on FLIR Tools software to determine if and where inflammation was detected on the carcass. Trimming occurs throughout the slaughter process, but carcasses may be ‘railed out’ if additional trimming is necessary. Trim loss was collected from railed out carcasses and weighed. The impact of rail-out status on trim loss was significant (P < 0.0001). Carcasses that were railed out (n = 15) yielded 16.2 ± 2.0 kg of trim loss. Carcasses that were not railed out (n = 21) did not experience additional trim loss. Carcasses railed out for additional trimming where inflammation suggested bruising existed (n = 7) yielded 21.0 ± 4.8 kg of trim loss. Carcasses railed out for trimming where thermography did not detect bruising (n = 4) yielded 12.6 ± 6.4 kg of trim loss. The relationship between thermographic detection of bruises and trim loss among railed-out carcasses was not significant (P = 0.3200). Inflammation that predicted rail-out events was 63.64% while carcasses in which rail-out was not detected by thermography was 36.36%. It appears that infrared thermography has potential to identify carcass bruising but additional investigation is warranted to understand its limitations.

A measurement of energy efficiency in the construction industry aims to reduce permanently energy requirements in design, construction and use of new buildings, sannation and reconstruction of the existing ones. Over the long term, with the expected increasing in the price of energy and the development of awareness about energy conservation and environmental protection, thermal imaging methods will certainly find their wide application in the construction industry. Infrared thermal camera is used to estimate the temperature. However, we do not see all the details of interest on the thermal image, therefore we suggest using the fusion of visual and thermal images of the same part of the building recorded simultaneously. The analysis images of the object obtained by fusion of television and infrared thermal imaging shows the areas of interest for further processing.

We have detected defects micro-pipes and a cluster of impurities in semi-insulating 6H-SiC substrates using long-wavelength infrared thermal imaging camera (IR-camera) with 8 ~ 14 µm in non-destructive and non-contact. Also we have evaluated the thermal influence of defects on the entire substrates from the observation results of scanning laser microscope (SLM) and light scattering tomography (LST). Through the process, it was certificated that the defects in the substrates could be detected with relatively macroscopic scale (8  6 mm2). Moreover, through a temperature profile processing by a 0.1 K thermal resolution, we estimated thermal behavior of the defect areas in the 6H-SiC precisely. The IR-camera is considered as effective technique for evaluating the defects in the intermediate range between micro and macro scale.
