Optimal Control of Applications for Hybrid Cloud Services
Development of cloud computing enables to move Big Data in the hybrid cloud
services. This requires research of all processing systems and data structures
for provide QoS. Due to the fact that there are many bottlenecks requires
monitoring and control system when performing a query. The models and
optimization criteria for the design of systems in a hybrid cloud
infrastructures are created. In this article suggested approaches and the
results of this build.Comment: 4 pages, Proc. conf. (not published). arXiv admin note: text overlap

Multiplicity estimate for solutions of extended Ramanujan's system
We establish a new multiplicity lemma for solutions of a differential system
extending Ramanujan's classical differential relations. This result can be
useful in the study of arithmetic properties of values of Riemann zeta function
at odd positive integers (Nesterenko, 2011)
Nonexistence of steady waves with negative vorticity
We prove that no two-dimensional Stokes and solitary waves exist when the
vorticity function is negative and the Bernoulli constant is greater than a
certain critical value given explicitly. In particular, we obtain an upper
bound for the Froude number of solitary waves with a
negative constant vorticity, sufficiently large in absolute value
