Hidden Markov model (HMM) has been well studied and extensively used. In this paper, we present DPHMM (Differentially Private Hidden Markov Model), an HMM embedded with a private data release mechanism, in which the privacy of the data is protected through a graph. Specifically, we treat every state in Markov model as a node, and use a graph to represent the privacy policy, in which “indistingu...

In this general lecture, we shall rst outline the way computational non-Newtonian uid mechanics di ers from conventional CFD. We do this by brie y outlining the major historical developments in this relatively new eld of science, which is conveniently called Computational Rheology. To illustrate essential features, we limit the discussion to the Oldroyd B, UCM and Phan-Thien/Tanner constitutive...

We investigate finite amplitude stability of spatially inhomogeneous steady state an incompressible viscoelastic fluid which occupies a mechanically isolated vessel with walls kept at non-uniform temperature. For wide class models including the Oldroyd-B model, Giesekus FENE-P Johnson–Segalman and Phan–Thien–Tanner model we prove that is stable subject to any perturbation.

conclusions the results showed that the level of respect for informational privacy was relatively acceptable. however, the level of respect for physical privacy was poor. therefore, it is essential to provide appropriate training on the issue of children’s privacy, especially physical privacy (e.g., using separate rooms and ensuring that medical staff knock before entering a room), and to ensur...
