The probabilistic model is built on the assumption that a time series of students’ application downloads and activations can be represented by individual inter-personal influence factors which consist of latent groups. To verify that model with its assumption‚ about 160 university students voluntarily participated in a mobile application usage monitoring experiment. Analysis could identify latent user groups by observing predictive

Cooling Drinks 1) What is the specific latent heat of fusion of water? Specific latent heat of fusion is the amount of heat absorbed or released by a substance when changing states. This could be boiling or melting. Latent heat of fusion is the amount of energy needed to melt a substance‚ while latent heat of vaporisation is the amount of energy needed to boil a substance. The specific latent heat of fusion of water is 334 j/g In the graph‚ you can see that as the temperature increases more
