($k$,$\epsilon$)-Anonymity: $k$-Anonymity with $\epsilon$-Differential Privacy
The explosion in volume and variety of data offers enormous potential for research and commercial use. Increased availability of personal data is of particular interest in enabling highly customised services tuned to individual needs. Preserving the privacy of individuals against reidentification attacks in this fast-moving ecosystem poses significant challenges for a one-size fits all approach...
متن کاملA Comparative Study of Omega RSM and RNG k–Epsilon Model for the Numerical Simulation of a Hydrocyclone
The design and optimization of hydrocyclones using CFD techniques are gaining popularity and the key to a successful simulation lies with the accurate description of the high turbulent swirling behavior of the flow. This paper presents a detailed co...

the design and optimization of hydrocyclones using cfd techniques are gaining popularity and the key to a successful simulation lies with the accurate description of the high turbulent swirling behavior of the flow. this paper presents a detailed comparison between the omega rsm and the rng k–e turbulence model, which are both derived specially for modeling swirling or rotational flow, in the s...
متن کاملApproximating capacitated $k$-median with $(1+\epsilon)k$ open facilities
In the capacitated k-median (CKM) problem, we are given a set F of facilities, each with a capacity, a set C of clients, a metric d over F ∪ C and an integer k. The goal is to open k facilities in F and connect the clients C to the open facilities subject to the capacity constraints, so as to minimize the total connection cost. In this paper, we give a constant approximation for CKM, by violati...
متن کاملA note on the numerical treatment of the k-epsilon turbulence model
Numerical solution of the equations arising from the turbulence model has difficulties inherent to nonlinear convection-reaction-diffusion equations with strong reaction terms, resulting in that numerical schemes easily become unstable. We present a formulation that stresses on the robustness of the solution method, tackling common problems that produce instability. The main contribution concer...
