Challenges of measuring body temperatures of free-ranging birds and mammals [PDF]
, 2015 The thermal physiology of most birds and mammals is characterised by considerable spatial and temporal variation in body temperature. Body temperature is, therefore, a key parameter in physiological, behavioural and ecological research.

Active Thermography in Qualitative Evaluation of Protective Materials [PDF]
International Journal of Occupational Safety and Ergonomics, 2009 This is a study of the possibilities of a qualitative evaluation of protective materials with active thermography. It presents a simulation of a periodic excitation of a multilayer composite material. Tests were conducted with lock-in thermography on Kevlar composite consisting of 16 layers of Kevlar fabric reinforced with formaldehyde resin with ...
