Glass transitions are characterized by large apparent activation energies and entropies. However, at sufficiently high temperatures, the activation entropy decreases to zero. This is a characteristic of noncooperative internal motions. The frequency-temperature relationship can be fitted by an equation which...
RELATIONSHIP BETWEEN THE TEMPERATURE AND FREQUENCY DEPENDENCE OF THE DAMPING PROPERTIES OF NATURAL RUBBER WITH DIFFERENT EPOXIDATION LEVELTwo common ways to control noise is either by reducing the power radiated by the source or through insulation. The latter method is used widely whenever it is not ...
and wave action to ships, buildings, trees, crops, roads, and railways, and they may interruptairservice and communications. Heavy snowfall and icy conditions can impede transportation and increase the frequency of accidents. The long absence of rainfall, by contrast, can cause droughts and severe...
Relationship between the Bond Valence and the Temperature Coefficient of the Resonant Frequency in the Complex Perovskite (Pb1−xCax)[F... The temperature coefficient of the resonant frequency (TCF) of complex perovskite (Pb1−xCax)[Fe0.5(Nb1−yT... Heung,Soo,Park,... - 《Journal of...
13. Palaeoclimate proxy data from high-quality geological archives can help improve projections of future water availability by probing the stability of the relationship between effective moisture and temperature over a range of past temperatures large enough to determine whether the Horn of Africa’s ...
First, the major frequency orders affected by temperature were derived from the tested multi-order natural frequencies through correlation analysis. Second, the PSO neural network algorithm was adopted to analyze the measured data, and the relationship between temperature and natural frequency was ...
Optimal Design Methodology for Frequency Compensation Circuits in Logging Cable Transmission Channel Analytical expressions are derived for the relationship between pole-zero and gain, deviations caused by high temperature; and are then verified via ...

Wien studied the wavelength or frequency distribution of blackbody radiation in the 1890s. It was his idea to use as a good approximation for the ideal blackbody an oven with a small hole. Any radiation that enters the small hole is scattered and reflected from the inner walls of the oven ...
where kB is the Boltzmann constant, and ν0 = 3 × 1011 s−1 is the average vibrational frequency of the normal mode along the MEP direction in the initial state30. Similarly, the critical strain \({\varepsilon }_{{{\rm{c}}}^{{{\rm{bwd}}}\) for the reverse transfo...
Driven by rapid urbanization, China has witnessed significant changes in urban LULC that have substantially impacted urban thermal environments over recent decades11,19,34. Studies have revealed that urbanization intensifies the frequency of extreme climate events, and its influence on AP is more profoun...
