We studied the relationship between the phase and the amplitude of the circadian temperature rhythm using questionnaires that measure individual differences in personality variables, variables that relate to circadian rhythms, age and sex. The ambulatory core body temperature of 101 young men and 71 young women was recorded continuously over 6 days. The temperature minimum (Tmin) and amplitude ...

We have developed the theory for using the deflection of laser beams of various wavelengths to determine molecular and thermal diffusion coefficients in multicomponent mixtures. In the past, simultaneous determination of molecular and thermal diffusion coefficients have only been achieved for binaries. Our procedure is faster and more accurate than the current techniques to determine molecular ...

The feasibility of using ultrasound-based elastic modulus imaging to visualize thermal ablation zones in an in vivo porcine model is reported. Elastic modulus images of soft tissues are estimated as an inverse optimization problem. Ultrasonically measured displacement data are utilized as inputs to determine an elastic modulus distribution that provides the best match to this displacement field...

Infrared thermal imaging of the breast, a non-invasive adjunctive diagnostic methodology has become all but non-existent in the United States. This is in large part due to extensive debate concerning thermography in the trial courts, related to spinal injury cases and also due to the model or basis used for breast thermal imaging. This paper attempts to identify possible factors which will brin...

This is a review of thermal imaging methods used for the measurement of body surface temperatures, including the most important medical applications, papers on thermal maps of people with various body compositions, and the applicability of thermal imaging in sport training.

Intermolecular Multiple Quantum Coherences Enable Accurate Thermal Imaging of Red Bone Marrow During Thermal Therapy of Bone Metastases by Ryan M Davis Department of Biomedical Engineering Duke University Date:_______________________ Approved: ___________________________ Warren S.

Thermal strain imaging (TSI) or temporal strain imaging is an ultrasound application that exploits the temperature dependence of sound speed to create thermal (temporal) strain images. This article provides an overview of the field of TSI for biomedical applications that have appeared in the literature over the past several years. Basic theory in thermal strain is introduced. Two major energy s...

Thermal camera operating in Far Infrared (FIR) is considered to be underexplored in fields other than security and law enforcement. Nevertheless, recently it drawn the attention of Human Computer Interaction (HCI) researchers as a new sensory system enabling novel interactive systems. They are robust to illumination changes and using it with well-known computer vision techniques, the complexity...

We propose a revolutionary concept for detecting suspects engaged in illegal and potentially harmful activities in or around critical military or civilian installations. We investigate the use of thermal image analysis to detect at a distance facial patterns of anxiety, alertness, and/or fearfulness. This is a totally novel approach to the problem of biometric identification. Instead of focusin...
