On the simulations of correlated nakagami-m fading channels using sum-of-sinusoids method
… from sum-of-sinusoids method in which Nakagami process is generated by taking square root of Gamma process. Gamma process itself can be realized using Gaussian processes. We have used Improved Jake's Model to characterize the low-pass Gaussian Processes. We also studied second order statistics …

Sampling error of the supremum of a Lévy process
… supremum and discrete maximum of a Lévy process that is often used in finance. We will show that the expected difference is a quantity that highly depends on the variational property of the underlying Lévy process. Two techniques are used with respect to the cases of the complexity of the …

Measurement of cross section times branching ratio for W boson + photon and Z boson + photon and search for anomalous W boson-photon and Z boson-photon couplings at 1.8 TeV
… cross section times branching ratio for $W + \gamma$ and $Z + \gamma$ processes, where the W decays into a muon and neutrino and the Z decays into a muon pair, have been made from the analysis of 18.6 $\pm$ 0.7 $pb\sp{-1}$ of high-$P\sb{T}$ muon data from proton-antiproton (pp) collisions. The …

Study of relaxation processes in simple glass formers by means of 2H NMR spectroscopy
… study the properties of the secondary relaxation processes (beta-processes) in the glassy state (0.5Tg<T<Tg). For several systems we also acquired NMR data at temperatures corresponding to the supercooled liquid state (T>Tg) providing information on the main relaxation process (alpha-process). In …

Diboson physics with CMS detector
… at Large Hadron Collider (LHC). A study of Z+gamma process is performed on the data collected by the CMS during 2011 and corresponding to integrated luminosity L= 5 fb[superscript]-1. The study consists of two parts: cross section measurement and setting the limits on anomalous trilinear gauge …

Optimal inspection and maintenance for stochastically deteriorating systems
… may be modelled by a continuous time stochastic process. Our emphasis is mainly on using the information gained from inspecting the degradation to determine efficient maintenance and inspection policies. The system we shall consider is one in which the degradation is modelled by a Levy process, …

Reliability-based performance assessment and optimum maintenance of corroded reinforced concrete structures
… bond failure between the rebar and concrete. The gamma process is adopted for stochastic modelling of concrete crack growth and strength deterioration with uncertainties. Then, a time-dependent reliability analysis is undertaken to evaluate the probability of failure in serviceability and load …

Z \(\gamma\) + differential cross section measurements and the digital timing calibration of the level-1 calorimeter trigger cluster processor system in ATLAS
… the reconstruction of \(Z\)(\(\to\) \({ee}\))\(\gamma\) events with the ATLAS detector at the LHC. The capabilities of the detector are explored for the initial run scenario with a proton-proton centre of mass collision energy of \(\sqrt{s}\) = 7TeV, and an integrated luminosity of …

Nonparametric Bayesian Modelling in Machine Learning
… Bayesian non-parametric inference. The Dirichlet process and its extensions are priors on an infinite-dimensional space. Originally introduced by Ferguson (1983), its conjugacy property allows a tractable posterior inference which has lately given rise to a significant developments in applications …

Integrated Workload Allocation and Condition-based Maintenance Threshold Optimisation
… maintenance optimisation model based on Gamma Process at the asset level through a machine agent; and 2) a workload allocation strategy at the system level implemented by a coordinator agent. Numerical analysis is performed to demonstrate the rationale behind the decision-making process, …
