This article addresses the problem of finding an optimal allocation of funds among different asset classes in a robust manner when the estimates of the structure of returns are unreliable. Instead of point estimates used in classical mean-variance optimization, moments of returns are described using uncertainty sets that contain all, or most, of their possible realizations. The approach present...

Radio-frequency transducers for obtaining primary information about parameters of the flows of mixes in pipelines are proposed. Sensors of transducers are resonators of a special construction, which do not create interference with the flow. The dependences of resonance frequency and amplitude of oscillations of resonators on the volumetric content of components of twoand three-component emulsio...

We analyse the mixing time of Markov chains using path coupling with stopping times. We apply this approach to two hypergraph problems. We show that the Glauber dynamics for independent sets in a hypergraph mixes rapidly as long as the maximum degree ∆ of a vertex and the minimum size m of an edge satisfy m ≥ 2∆+1. We also state results that the Glauber dynamics for proper q-colourings of a hyp...

We give a new method for analysing the mixing time of a Markov chain using path coupling with stopping times. We apply this approach to two hypergraph problems. We show that the Glauber dynamics for independent sets in a hypergraph mixes rapidly as long as the maximum degree ∆ of a vertex and the minimum size m of an edge satisfy m ≥ 2∆ + 1. We also show that the Glauber dynamics for proper q-c...
