THERMAL EFFECTS ON CAMERA FOCAL LENGTH IN MESSENGER STAR CALIBRATION AND ORBITAL IMAGING
Mercury, MESSENGER, MDIS Camera Digital Terrain Models
2018/5/11
We analyse images taken by the MErcury Surface, Space ENviorment, GEochemistry, and Ranging (MESSENGER) spacecraft for the camera’s thermal response in the harsh thermal environment near Mercury. Spec...
Thermal stresses analysis of casing string used in enhanced geothermal systems wells
Casing deformation and collapse Pre-tension stress cementing Well completion design Pre-stressed cementing
2018/3/23
In the enhanced geothermal systems wells, casing temperature variation produces casing thermal stresses, resulting in casing uplift or bucking. When the induced thermal stresses exceed casing material...
Ion thermal effects on E-region instabilities: 2D kinetic simulations
E-region electrojet Ionospheric irregularities Plasma instabilities
2017/3/22
Radars frequently receive strong returns from naturally occurring plasma density irregularities centered around
100 km altitude in the atmosphere. These E-region ionospheric irregularities occur when...
QUALITATIVE SCREENING METHOD FOR IMPACT ASSESSMENT OF UNCERTAIN BUILDING GEOMETRY ON THERMAL ENERGY DEMAND PREDICTIONS
Morris method Qualitative ranking Energy Demand CityGML
2016/10/14
Virtual 3D models of cities are now being extensively employed for the estimation of thermal energy demand at varying spatial and temporal scales. Efforts in preparing and management of the datasets r...
Robust satellite techniques (RST) for the thermal monitoring of earthquake prone areas:the case of Umbria-Marche October,1997 seismic events
earthquake satellite-thermal-infrared Meteosat Umbria-Marche RST
2015/9/1
Several authors claim a space-time correlation between increases in Earths emitted Thermal Infra-Red (TIR) radiation and earthquake occurrence. The main problems of such studies regard data analysis a...

Thermal diffusivity Soil temperature Soil moisture content West Africa
2015/8/18
This study presents comparisons between six algorithms used in the calculation of apparent thermal diffusivity (Kh) of the topsoil during measurement campaigns conducted at two equatorial sites. It fu...
Density-thermal dependence of sedimentary associations calls to reinterpreting detailed gravity surveys
Temperature Density Subvertical zone Gravity anomaly
2015/8/14
The modern gravimetric equipment allows to register very small effects of gravity field changes and can be applied solving different geological, geophysical and environmental problems. However, someti...

Climate change phenomenon permafrost active layer radiation layer temperature data monitoring in southern hemisphere circumpolar active layer
2015/1/6
International attention to climate change phenomena has grown in the last decade; the active layer and permafrost are of great importance in understanding processes and future trends due to their role...
Thermal conditions during deformation of partially molten crust from TitaniQ geothermometry: rheological implications for the anatectic domain of the Araçuaí belt, eastern Brazil
Neoproterozoic orogeny the earth's crust the three-dimensional deformation deep source middle crust
2015/1/6
During the Neoproterozoic orogeny, the middle crust of the Araçuaí belt underwent widespread partial melting. At the regional scale, this anatectic domain is characterized by a progressive rotati...
Thermal shock and splash effects on burned gypseous soils from the Ebro Basin (NE Spain)
Thermal shock splash effects gypseous soils the Ebro Basin
2015/1/6
Fire is a natural factor of landscape evolution in Mediterranean ecosystems. The middle Ebro Valley has extreme aridity, which results in a low plant cover and high soil erodibility, especially on gyp...
The ring-shaped thermal field of Stefanos crater, Nisyros Island: a conceptual model
The ring-shaped thermal field Stefanos crater, Nisyros Island conceptual model
2015/1/6
Fumarole fields related to hydrothermal processes release the heat of the underground through permeable pathways. Thermal changes, therefore, are likely to depend also on the size and permeability var...
