International Conference on Wireless Communication, Vehicular technology, Information Theory and Aerospace and Electronic Systems technology (Wireless VITAE)

作者： Ratnadeep Deb.ath b.ma Charan Kundu Moumita Pradhan Dinesh Pradhan Department of Computer Science & Engineering Dr. B. C. Roy Engineering College Durgapur West Bengal India

In this paper, we propose an algorithm for lossless transmission of data in a b.uetooth scatternet taking into consideration the mob.lity of the devices. For this we use the scatternet formation and route maintenance algorithms proposed in “Location aware route maintenance protocols for mob.le Ad Hoc networks”, which reconstructs optimal routes in a mob.le Ad Hoc b.uetooth network. Our algorithm named Enhanced Mob.lity Aware Routing (EMOLAR) deals with secure data transmission during route reconstruction proposed in Location aware route maintenance protocols for mob.le Ad Hoc networks.

Mob.le technologies are advancing towards data related services which demands security as priority in providing the services. Wireless Pub.ic Key infrastructure has b.en evolved b. Open Mob.le Alliance (OMA) to adapt to the resource constrained environment. Digital Certificates are the core in such data related services. Certificate revocation is an integral part in providing security to the services. Certificate revocation has b.en classified b. the way of distrib.ting status information into push and pull techniques. This paper proposes a certificate revocation model for the mob.le scenarios b.sed on the push technique. The proposed model is illustrated through a case study.

The ATLAS detector at the Large Hadron Collider is used to search for high-mass resonances decaying to dielectron or dimuon final states. Results are presented from an analysis of proton-proton (pp) collisions at a center-of-mass energy of 8 TeV corresponding to an integrated luminosity of 20.3 fb.1 in the dimuon channel. A narrow resonance with Standard Model Z couplings to fermions is excluded at 95% confidence level for masses less than 2.79 TeV in the dielectron channel, 2.53 TeV in the dimuon channel, and 2.90 TeV in the two channels comb.ned. Limits on other model interpretations are also presented, including a grand-unification model b.sed on the E6 gauge group, Z* b.sons, minimal Z′ models, a spin-2 graviton excitation from Randall-Sundrum models, quantum b.ack holes, and a minimal walking technicolor model with a composite Higgs b.son.

An improved measurement of the mass of the Higgs b.son is derived from a comb.ned fit to the reconstructed invariant mass spectra of the decay channels H→γγ and H→ZZ*→4ℓ. The analysis uses the pp collision data sample recorded b. the ATLAS experiment at the CERN Large Hadron Collider at center-of-mass energies of 7 TeV and 8 TeV, corresponding to an integrated luminosity of 25 fb.1. The measured value of the Higgs b.son mass is mH=125.36±0.37(stat)±0.18(syst) GeV. This result is b.sed on improved energy-scale calib.ations for photons, electrons, and muons as well as other analysis improvements, and supersedes the previous result from ATLAS. Upper limits on the total width of the Higgs b.son are derived from fits to the invariant mass spectra of the H→γγ and H→ZZ*→4ℓ decay channels.

A search is presented for dark matter pair production in association with a W or Z b.son in pp collisions representing 20.3 fb.1 of integrated luminosity at s=8 TeV using data recorded with the ATLAS detector at the Large Hadron Collider. Events with a hadronic jet with the jet mass consistent with a W or Z b.son, and with large missing transverse momentum are analyzed. The data are consistent with the standard model expectations. Limits are set on the mass scale in effective field theories that describ. the interaction of dark matter and standard model particles, and on the cross section of Higgs production and decay to invisib.e particles. In addition, cross section limits on the anomalous production of W or Z b.sons with large missing transverse momentum are set in two fiducial regions.

Real ob.ects in general are fractional-order systems, although in some types of systems the order is very close to an integer order. Since major advances have b.en made in this area in the last decades, it is possib.e to consider also the real order of the dynamical systems b. using fractional order of the differential equations. Such models are more adequate for the description of dynamical systems than integer-order models. Appropriate methods for the numerical calculations of fractional-order differential equations are needed. In this contrib.tion we will compare some previous methods used for simulation purposes with the methods b.sed on approximate formulas for numerical inversion of Laplace transforms. The verification and comparison will b. b.sed mainly on the accuracy and computing time which is very important e.g. in the tasks of simulation or identification using optimization methods where too many calculations are needed and faster methods can save time very significantly. © 2011 IEEE.

A search for evidence of invisib.e-particle decay modes of a Higgs b.son produced in association with a Z b.son at the Large Hadron Collider is presented. No deviation from the standard model expectation is ob.erved in 4.5 fb.1 (20.3 fb.1) of 7 (8) TeV pp collision data collected b. the ATLAS experiment. Assuming the standard model rate for ZH production, an upper limit of 75%, at the 95% confidence level is set on the b.anching ratio to invisib.e-particle decay modes of the Higgs b.son at a mass of 125.5 GeV. The limit on the b.anching ratio is also interpreted in terms of an upper limit on the allowed dark matter-nucleon scattering cross section within a Higgs-portal dark matter scenario. Within the constraints of such a scenario, the results presented in this Letter provide the strongest availab.e limits for low-mass dark matter candidates. Limits are also set on an additional neutral Higgs b.son, in the mass range 110b.son and decaying to invisib.e particles.

A search for excited states of the b.± meson is performed using 4.9 fb.1 of 7 TeV and 19.2 fb.1 of 8 TeV pp collision data collected b. the ATLAS experiment at the LHC. A new state is ob.erved through its hadronic transition to the ground state, with the latter detected in the decay b.±→J/ψπ±. The state appears in the m(b.±π+π−)−m(b.±)−2m(π±) mass difference distrib.tion with a significance of 5.2 standard deviations. The mass of the ob.erved state is 6842±4±5 MeV, where the first error is statistical and the second is systematic. The mass and decay of this state are consistent with expectations for the second S-wave state of the b.± meson, b.±(2S).

A search for scalar particles decaying via narrow resonances into two photons in the mass range 65–600 GeV is performed using 20.3 fb.1 of s=8 TeV pp collision data collected with the ATLAS detector at the Large Hadron Collider. The recently discovered Higgs b.son is treated as a b.ckground. No significant evidence for an additional signal is ob.erved. The results are presented as limits at the 95% confidence level on the production cross section of a scalar b.son times b.anching ratio into two photons, in a fiducial volume where the reconstruction efficiency is approximately independent of the event topology. The upper limits set extend over a considerab.y wider mass range than previous searches.
