Hierarchical MPC of Hybrid Power Systems based on Fuzzy Discrete Abstraction
(IFAC-PapersOnLine;Volume 53, Issue 2, 2020, Peer reviewed; Journal article, 2020-04-14)A hierarchical control approach is proposed for hybrid systems with discrete-valued input based on fuzzy discrete abstraction and model predictive control (MPC) scheme. The system is firstly abstracted to a discrete event ... -
High Availability and Performance of Database in the Cloud - Traditional Master-slave Replication versus Modern Cluster-based Solutions
(Chapter; Peer reviewed, 2017)High availability (HA) of database is critical for the high availability of cloud-based applications and services. Master-slave replication has been traditionally used since long time as a solution for this. Since ... -
High-frequency expansions for time-periodic Lindblad generators
(Physical review B (PRB);104, 165414, Peer reviewed; Journal article, 2021-10-15)Floquet engineering of isolated systems is often based on the concept of the effective time-independent Floquet Hamiltonian, which describes the stroboscopic evolution of a periodically driven quantum system in steps of ... -
High-resolution lead–lag relations between Barents Sea temperatures, the AMOC and the AMO during 1971-2018
(Peer reviewed; Journal article, 2023)The direction of heat transport from the atmosphere to the Barents Sea, and between the Barents Sea and the North Atlantic is important for understanding the interplay between Greenland ice melting and anthro- pogenic ... -
Higher harmonics of azimuthal anisotropy in relativistic heavy-ion collisions in HYDJET++ model
(The European Physical Journal C;74(3), Journal article; Peer reviewed, 2014)The LHC data on azimuthal anisotropy harmonics from PbPb collisions at center-of-mass energy 2.76TeV per nucleon pair are analyzed and interpreted in the framework of the HYDJET++ model. The cross-talk of elliptic v2 and ... -
The Hilbert Scheme of Buchsbaum space curves
(Annales de l'Institut Fourier;62, Journal article; Peer reviewed, 2012)We consider the Hilbert scheme H(d,g) of space curves C with homogeneous ideal I(C):=H_{*}^0(\sI_C) and Rao module M:=H_{*}^1(\sI_C). By taking suitable generizations (deformations to a more general curve C') of C, we ... -
