The current state of the problem of distributed attacks aimed at denial of service is investigated, the last DDoS attacks are monitored. The most popular type of DDoS attacks continues to be httpflood. The modern methods of diagnosing DDoS-attacks are investigated. Positive and negative aspects of these methods were identified.
Methods and software were developed for studying parameters of frequency dispersion for radio links of different length. We used SDR based sounding system for studying a HF radio channel and determining parameters of frequency dispersion. The software component was implemented using licensed software Lab VIEW. The hardware component was implemented using a programmable transceiver USRP N210. We studied...
Methods and software are developed for research the effects of phase dispersion, depending of the ionospher, based on LabVIEW. It is found that the leading edge increased with increasing of the third order parameter of impulse response, which leads to the case without the frequency dispersion, while trailing edge moving away from the peak, which leads to the case of linear frequency dispersion. Ionospheric...
A new heavy gauge boson, W′, decaying to a muon and a neutrino, is searched for in pp collisions at a centre-of-mass energy of 7 TeV. The data, collected with the CMS detector at the LHC, correspond to an integrated luminosity of 36 pb−1. No significant excess of events above the standard model expectation is found in the transverse mass distribution of the muon–neutrino system. Masses below 1.40...
A measurement of W+W− production in pp collisions at s=7 TeV and a search for the Higgs boson are reported. The W+W− candidates are selected in events with two leptons, either electrons or muons. The measurement is performed using LHC data recorded with the CMS detector, corresponding to an integrated luminosity of 36 pb−1. The pp → W+W− cross section is measured to be 41.1±15.3(stat)±5.8(syst)±4...
