DTA method applikation to the highest refractory oxide systems investigation
Thermochimica Acta, 1985Abstract DTA method application to the controlled gaseous environment up to the temperature of 2600°C and TA method application in air using solar heating up to the 3000°C are considered. Phase trans formations in the highest refractory systems based on the lanthanide oxides: zirconium, hafnium, yttrium oxides as well as IIA subgroupe element oxides ...

Oxidation stability of polymeric materials dynamic DSC/DTA method
Journal of Thermal Analysis, 1982The dynamic DSC/DTA method was observed to give better selectivity and reproducibility than the isothermal method when estimating relative oxidation stability of plastics materials. The dynamic DSC/DTA method is in this survey exposed to a round robin test.

A new method for DTA measurement of enthalpy change during the pyrolysis of rubbers
Thermochimica Acta, 1996Abstract A novel approach involving the use of DTA to measure quantitatively the enthalpy change during rubber atmospheric pyrolysis was developed and applied to tire rubbers: NR (natural rubber), SBR (styrene-butadiene rubber) and BR (butadiene rubber).

A new DTA method for measuring critical cooling rate for glass formation
Journal of Non-Crystalline Solids, 2005A new differential thermal analysis (DTA) experimental method has been developed to determine the critical cooling rate for glass formation, R(sub c). The method, which is found especially suitable for melts that, upon cooling, have a small heat of crystallization or a very slow crystallization rate, has been verified using a 38Na2O-62SiO2 (mol%) melt ...

Evaluation of the number density of nuclei in Li2O·2SiO2 glass by DTA method
Journal of Non-Crystalline Solids, 2001Abstract DTA measurements were performed to obtain the crystallization peak temperature, TC, for Li2O·2SiO2 glass heat-treated for nucleation. The relationship between TC and the number density of nuclei was obtained. Calculation of TC was performed by simulating the crystallization process, and the effects of the size and the number density of ...

An investigation of AlN nanoparticles by DTA and DTG methods
UNEC journal of engineering and applied sciences, 2023Differential thermal analysis (DTA) and differential thermal gravimetry (DTG) studies at different heating rates of were considered for AlN nanoparticles. The free Gibbs energy in the temperature range of 300÷1400 K is determined at 5, 10, 15 and 20 K/min heating rates.

A new method of DTA: Theory and practice
Journal of Thermal Analysis, 1973A novel differential thermoanalytical technique is described and discussed with regard to function, operation, performance, theory and application. Information is provided about the nature of the internal processes taking place at the time of absorption or release of energy. Notable features of the technique include high sensitivity and independence of

Real-time traffic forecasting with recent DTA methods
2017 5th IEEE International Conference on Models and Technologies for Intelligent Transportation Systems (MT-ITS), 2017In this paper we revisit the real-time traffic forecasting problem. We review recently proposed Dynamic Traffic Assignment (DTA) methods and verify how they can improve the practice of traffic forecasting. In particular, we analyze: 1) the Gradient projection DTA model of Gentile (2016), 2) Day-to-day model by Watling and Cantarella (2016), 3) the ...
