Abstract This research deals with continuous surface body temperature measurements in cow using IR based thermometry. Body surface temperatures were estimated contactless utilizing recordings from an IR thermometry fixed at a specific region in the cow. The body surface temperatures were dissected reflectively at two regions: the rectal region (behind the tail) and abdominal region (nearer the stomach) in the cow. The traditional invasive rectal temperature filled in as a kind of perspective temperature and was estimated with a computerized thermometer at the comparing time point. An aggregate of ten cows (Redsindhi, HF cross, Kangayam ) was inspected. The normal most extreme temperatures of the territory of the rectal (mean ± SD: 38.69 ± 0.5°C) and the abdominal region (38.4 ± 0.51°C). The temperatures of these regions in the cow were 95% accurate than the traditional invasive rectal temperature measurements. Notwithstanding, the most extreme temperatures as estimated utilizing IR thermometry expanded with an expansion in cow rectal temperature. These temperature readings are then been communicate to the remote server for continuous monitoring of the condition of cows. This communication is carried out by using Bluetooth/Wifi medium. Since this framework comes out with a non-invasive fashion measuring surface body temperature, will be an alternate way of taking a reading of temperature rather than computing the internal body temperature in an invasive fashion. Subsequently, this IR thermometry shows potential as a marker for consistent temperature estimations in cows.

This paper refers to a numerical study of the hypo-thermal behaviour of a pine tree in a forest fire environment. The pine tree thermal response numerical model is based on energy balance integral equations for the tree elements and mass balance integral equation for the water in the tree. The simulation performed considers the heat conduction through the tree elements, heat exchanges by convection between the external tree surfaces and the environment, heat exchanges by radiation between the flame and the external tree surfaces and water heat loss by evaporation from the tree to the environment. The virtual three-dimensional tree model has a height of 7.5 m and is constituted by 8863 cylindrical elements representative of its trunks, branches and leaves. The fire front has 10 m long and a 2 m high. The study was conducted taking into account that the pine tree is located 5, 10 or 15 m from the fire front. For these three analyzed distances, the numerical results obtained regarding to the distribution of the view factors, mean radiant temperature and surface temperatures of the pine tree are presented. As main conclusion, it can be stated that the values of the view factor, MRT and surface temperatures of the pine tree decrease with increasing distance from the pine tree in front of fire.
