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...
There has been a dramatic increase in interactive cloud based software applications. Compared to classical real-time media applications (voice over IP (VoIP)/conferencing) and non real-time file delivery, these interactive software applications have unique characteristics: 1) they are delay sensitive yet demand in order and reliable data delivery, and 2) the traffic is usually bursty. Traditional...
In this paper, an optimal aggregation and counter-aggregation (drill-down) methodology is proposed on multidimensional data cube. The main idea is to aggregate on smaller cuboids after partitioning those depending on the cardinality of the individual dimensions. Based on the operations to make these partitions, a Galois Connection is identified for formal analysis that allow to guarantee the soundness...
In this paper, a novel adaptive calibration technique for advanced RF front-ends is proposed in which sensors are implanted in the transmitter and the observed device test response to a special calibration test is compared against the known golden response to the same. Tuning 'knobs' which are built into the circuit are then used to minimize the error between the observed response and the golden response...
