Information Model of Cloud App Scaling with Variable Load Peaks
The information model of cloud app was done. It is a formal description of cloud app infrastructure and possible transitions between them, and cloud app current working state classification criterion. Cloud app current state classification criterion on the basis of Page-Hinckley method and calendar of events related to the cloud app working state considers the current state to one of three classes in order to improve the accuracy of prediction of cloud app workload.Proposed criterion was compared with standard offline criterion that analyzes information about the entire time series of cloud app through a considerable time after the events that lead to the load peak, and therefore can\u27t be used when grading in real time. It is shown that the classification of cloud app state is consistent in 92 % of cases.The resulting information model of cloud app scaling with variable load peaks can be used as a component of information technology for cloud app scaling with variable load peaks

Growth and characterization of ZnMnO thin films
Zn1−xMnxO (0 ≤ x ≤ 0.1) thin films were grown on sapphire substrates by pulsed laser
deposition and rf magnetron sputtering methods. As a target source ceramic pellets prepared by
mixing ZnO and Mn3O4 powders were used. The shift of the absorption edge due to increase the
energy band gap with increasing Mn content was observed in optical absorption spectra of the
Zn1−xMnxO thin films. Magnetic susceptibility and magneto-optical Faraday rotation experiments
show paramagnetic behavior and absence of ferromagnetic ordering in the studied films.This work has been supported in part by grant No. M/128-2004 from the Ministry of

Magneto-optical Faraday effect in II–VI based semimagnetic semiconductor nanocrystals
Different physical and chemical methods were used to prepare II–VI based semimagnetic semiconductor
nanocrystals. A study of magneto-optical Faraday effect in the nanocrystals revealed its enhancement as
compared with bulk crystals. It is explained in framework of increase in the oscillator strength of exciton
transitions and to the difference between these strengths in an external magnetic field. It was observed almost
linear dependence of the Faraday rotation as function of magnetic field strength for nanocrystals at
liquid helium temperature in contrast to the dependence with saturation in bulk case and changes in process
of a transition of the semimagnetic nanocrystals from the paramagnetic state to a spin glass state
Православна мiсiя в Японii на рубежi XIX - XX ст.
The work of the Orthodox Mission in Japan at the turn of the XIX - XX centuries forever changed map of religions in the Land of the Rising Sun. The National Japanese Orthodox Church was established and all the clergy were elected from among the Japanese themselves. The founder of the mission and its long-standing leader was the Archbishop Nikolai (Kasatkin). The article provides an overview of the main principles the mission was found upon and its activities.Праця православної місії в Японії на рубежі XIX - XX століть навічно змінила карту релігій на Землі Східного Сонця. Була створена Національна Японська Православна Церква, і всі духовенства були обрані з числа самих японців. Засновником місії та її давнім лідером був архієпископ Микола (Касаткін). У статті подано огляд основних принципів, якими характеризувалася місія та її діяльність

Resolvent convergence of Sturm-Liouville operators with singular potentials
In this paper we consider the Sturm-Liuoville operator in the Hilbert space
with the singular complex potential of and two-point boundary
conditions. For this operator we give sufficient conditions for norm resolvent
approximation by the operators of the same class.Comment: 6 pages, to appear in Math. Note
Effects of codoping in ZnO-based semimagnetic semiconductor thin films
Single doped Zn1-xMnxO, Zn1-xFexO and codoped Zn1-x-yMnxFeyO, Zn1-x-yMnxSnyO,
Zn1-x-yMnxLiyO, Zn1-x-yFexAlyO thin films were grown on sapphire and glass substrate by
pulsed laser deposition and RF sputtering techniques. No secondary phases was detected from
XRD analysis. Among the studied oxide films single doped with Fe and codoped with (Mn,Fe)
and (Fe, Al) exhibit n-type conductivity and room temperature ferromagnetic behaviour. For
the films codoped with (Mn, Sn) formation of clusters including nanowire-like structures was
shown from AFM analysis. Optical and magnetooptical studies suggest of Mn, Fe, Sn and Li
substitution for Zn2+ ions in ZnO lattice.This research was partially supported by the Ministry of Education and Science of Ukraine
