Thermal anomalies at volcanoes

2015
Thermal anomalies occur when a pixel in a satellite image shows a higher brightness temperature than is expected relative to its neighbors. Thermal anomalies have been observed over decades at volcanoes in satellite data. Such anomalies occur for many reasons, but at volcanoes this can be an indicator of volcanic activity or even a precursor to more ...

Thermal expansion anomaly of MnB

Physics Letters A, 1975
Abstract The thermal expansion of MnB has been measured in the temperature range from 0 to 420°C. An Invar type thermal expansion is observed. The thermal expansion coefficient is −42×10-6 deg.-1 at 295°C(≈Tc).

Residential Thermal Anomalies And Their Origins

SPIE Proceedings, 1985
Over the past few years, interest in the use of infrared thermography in residential dwellings has increased. With this growth comes the need for a better understanding of thermal images. Just as in other applications of thermal imaging, different thermal signatures represent different characteristics of the object being studied.

Thermal anomaly detection in datacenters

Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science, 2011
The high density of servers in datacenters generates a large amount of heat, resulting in the high possibility of thermally anomalous events, i.e. computer room air conditioner fan failure, server fan failure, and workload misconfiguration. As such anomalous events increase the cost of maintaining computing and cooling components, they need to be ...

Anomalies in the Thermal Properties of Water

Nature, 1969
IN this article we draw attention to the abrupt changes in the properties of water as a function of temperature which have been described as “anomalies in the already anomalous behaviour of water”1,2.

The spatial extent of thermal anomalies at Lascar Volcano

2010 IEEE International Geoscience and Remote Sensing Symposium, 2010
Lascar volcano (Chile) has undergone at least 4 vulcanian eruptions and other smaller events between May 2000 and April 2009. Multispectral, thermal infrared images taken during this time by ASTER are used to calculate surface temperatures. The spatial extent and intesity of thermal anomalies are interpreted as varying due to fluctuations in the ...

Lunar rocks and thermal anomalies

Journal of Geophysical Research, 1971
Recent microwave and infrared spectral observations of several of the large bright-rayed craters on the moon suggest that the thermal anomalies in these craters are produced by large rocks, boulders, and exposed rock strata. The data for the crater Tycho can be simulated by a surface consisting of 16% loose rocks of 1-meter size and 4% exposed rock ...

Thermal anomaly detection for 2013 Lushan earthquake

2016 IEEE International Geoscience and Remote Sensing Symposium (IGARSS), 2016
For some strong earthquakes, thermal anomaly occurs before the event, however not definitely. In this study, time series of MODIS Land Surface Temperature (LST) products have been processed and analyzed to locate possible anomalous variations prior to the Lushan (20 April 2013) earthquakes.

The thermal expansion anomaly of gadolinium

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1960
Abstract The thermal expansion of polycrystalline gadolinium has been measured from 80 to 750°K. The anomaly in the expansivity in the region of the ferromagnetic Curie point corresponds to an isotropic volume strain of 2⋅7 x 10-3. The connexion of the thermal expansion anomaly with the magnetostriction constants and the (hexagonal ...

Thermal Sensing and Anomaly Detection

2011
Thermal remote sensing directs our attention to the role of temperature and an indicator of land surface conditions and contrasts (Diak 1995; Xian and Crane 2006; Quattrochi and Luvall 1999). Recognizing that all surface objects with temperatures above absolute zero (0K) emit electromagnetic radiation, thermal remote sensing concentrates on the ...
