These servers, to ensure an acceptable level of reliabil- ity, should be equipped by systems for the backup of the status of the provided services and the data they deal with. keywords: active; analysis; applications; architecture; automatic; availability; available; case; computer; computing; continuity; cost; data; dormant; drbd; failback; failover; fault; federici; general; havms; high; integral; machine; management; manager; remus; resources; running; server; services; software; solution; storage; synchronization; system; time; use; virtual; xen cache: app01-2419.pdf plain text: app01-2419.txt item: #47 of 571 id: app01-2420 author: Tluczykont, M.; Brückner, M.; Budnev, N.; Chvalaev, O.; Dyachok, A.; Epimakhov, S.; Gress, O.; Hampf, D.; Horns, D.; Ivanova, A.; Kalmykov, N.; Konstantinov, E.; Korosteleva, E.; Kozin, V.; Kunnas, M.; Kuzmichev, L.; Lubsandorzhiev, B.; Mirgazov, R.; Monkhoev, R.; Nachtigall, R.; Panasyuk, M.; Pakhorukov, A.; Poleschuk, V.; Porelli, A.; Prosin, V.; Ptuskin, V.; Rubtsov, G.

The low accretion rate of the white dwarf in AE Aquarii (Ṁ∗ ∼ 1014 g s−1) compared to the mass transfer rate deduced from the UV emission line spectra (Ṁ2 ∼ 1017 g s−1) implies that the white dwarf in AE Aquarii is in a super-propeller (ejector) state (Bisikalo & Zhilkin 2012; Ikhsanov & Beskrovnaya 2012). keywords: accretion; ae aquarii; apj; aquarii; beskrovnaya; cataclysmic; dwarf; e.g.; emission; et al; field; high; horne; ikhsanov; magnetic; mass; meintjes; mnras; non; optical; order; p.j; patterson; period; propeller; rate; ray; secondary; spin; star; system; s−1; thermal; transfer; van; variables; venter; white cache: app01-2841.pdf plain text: app01-2841.txt item: #74 of 571 id: app01-2842 author: Latev, G.; Zamanov, R.; Boeva, S.; Stoyanov, K. title: Simultaneous UBVRI Observations of the AE Aquarii Blobs date: 2015-02-23 words: 2203 flesch: 64 summary: On time-scales of about 10 minutes, the light curve of AE Aqr displays flares with an amplitude up to ≈ 1 mag (see Fig.1 and Fig.2).
