Résumé :

Abstract Some simple arguments are introduced for a possible explanation of the behavior of the lateral shower age of proton-initiated showers. The corresponding analytical treatment based on the proposed argument is then illustrated. Using the Monte Carlo simulation (MC) code CORSIKA, we have validated how the different characteristics associated with the lateral shower age predicted in the present analytical parametrization, can be understood. The lateral shower age of a proton-initiated shower and its correlations with the lateral shower ages of electron- and neutral pion-initiated showers

Résumé :

The problem of incorporating exact 2→3 QCD cross sections into Monte Carlo models for hadron-hadron scattering is examined, and a simple, branching weight formalism which retains all the information of the 2→3 processes is presented. The connection of this prescription with the angle-ordered soft gluon results of Ellis, Marchesini and Webber is explored in detail. Possible unresolved questions for the procedure are also noted.

Résumé :

High transverse momentum (PT) QCD scattering processes are regarded as a valuable tool to study the medium produced in heavy-ion collisions, as due to uncertainty arguments their cross section should be calculable independent of medium properties whereas the medium then modifies only the final state partons emerging from a hard vertex. With the heavy-ion physics program at the CERN LHC imminent, the attention of high PT physics in heavy ion collisions is shifting from the observation of hard single hadrons to fully reconstructed jets. However, the presence of a background medium at low PT comp

As a basis for the interpretation of data gathered by LOPES and other experiments, we have carried out Monte Carlo simulations of geosynchrotron radio emission from cosmic ray air showers. The simulations, having been verified carefully with analytical calculations, reveal a wealth of information on the characteristics of the radio signal and their dependence on specific air shower parameters. In this article, we review the spatial characteristics of the radio emission, its predicted frequency spectrum and its dependence on important air shower parameters such as the shower zenith angle, the p

Résumé :

The lateral distribution (LD) of particles in extensive air showers (EAS) of cosmic rays (CRs) broadens as the cascade propagates in the atmosphere. A universal relation between LD parameters and shower age can be used to estimate the age and/or maximum depth, Xmax, basing on EAS measurements with surface arrays. We have simulated this relation using a Monte Carlo method implemented in the CORSIKA code. Our aim is to specify an algorithm applicable in particular to Yakutsk array data analysis.

Il parametro $m_t$ coincide con la massa fisica, che è collegata alla massa nuda attraverso una procedura di rinormalizzazione.

Résumé :

In the past years, next-to-leading order (NLO) QCD computations have become standard tools for phenomenological studies at lepton and hadron colliders. On the experimental side, instead, general purpose Shower Monte Carlo (SMC) programs have become the main tools used in the analysis. These programs perform a resummation of all order leading logarithmic contributions in soft and collinear approximation. The whole process is thus represented as a parton shower, in which subsequent emissions are strongly ordered. Being fully exclusive, it is easy to interface them with phenomenological

There are multiple complaints that existing project risk quantification methods—both parametric and Monte Carlo—fail to produce accurate project duration and cost-risk contingencies in a majority of cases.

It is argued that a project system consists of two interacting subsystems: a project structure subsystem (PSS) and a project delivery subsystem (PDS). Any misalignments or imbalances between these two subsystems (PSS–PDS mismatches) are associated

Résumé :

The timing capability of photomultipliers (PMTs) can be inferred from the basic laws of electron motion. The relationships between time dispersion and field strength, initial electron energy, angle of emission, and electrode spacing follow from these laws. For conventional PMTs, the major contribution to dispersion arises from the cathode-to-first-dynode region. The field gradient at the cathode primarily determines the timing. This is verified by examining the electron motion in non-uniform electric fields. The contribution from interdynode transitions is small for linear focussed PMTs. Monte

Résumé :

A new probabilistic approach to assess the reliability of brittle materials for high temperature engine components was developed. The probability of failure due the fracture of a randomly oriented damage inherent from manufacturing process was determined by a hybrid probabilistic method (HPM) for computational efficiency and accuracy. The random variables considered by this approach for overall component failure probability include fracture toughness, loads, geometric factor, initial damage size, damage growth rate, damage orientation and damage occurrence in a unit volume. HPM consists of fou

Résumé :

We study the use of multi-level Monte Carlo methods for wind engineering. This report brings together methodological research on uncertainty quantification and work on target applications of the ExaQUte project in wind and civil engineering. First, a multi-level Monte Carlo for the estimation of the conditional value at risk and an adaptive algorithm are presented. Their reliability and performance are shown on the time-average of a non-linear oscillator and on the lift coefficient of an airfoil, with both preset and adaptively refined meshes. Then, we propose an adaptive multi-fidelity Monte

Texte intégral

Résumé :

The common choice of using a direct forecasting scheme implies that the individual predictions ignore information on their cross-horizon dependence. However, this dependence is needed if the forecaster has to construct, based on direct density forecasts, predictive objects that are functions of several horizons (e.g. when constructing annual-average growth rates from quarter-on-quarter growth rates). To address this issue we propose using copulas to combine the individual h-step-ahead predictive distributions into one joint predictive distribution. Our method is particularly appealing to those

Résumé :

The analysis of a numerical benchmark for a pure 1-meter sphere of La-139 proposed by C. Konno using ACE- and MATXS-formatted cross section files from the FENDL-3.1c library showed problems in the unresolved resonance region (URR). The total neutron flux computed using MCNP/ACE differed up to 50% from the one calculated applying ANISN/MATXS. The problem arose when too small total cross section values were sampled by the PURR module of NJOY2016 mainly due to the limitations of the processing method. NJOY2016 (PURR) patch to correct this issue was proposed and applied. The patch increases the ne

Résumé :

We develop a novel pricing strategy that approximates the value of an American option with exotic features through a portfolio of European options with different maturities. Among our findings, we show that: (i) our model is numerically robust in pricing plain vanilla American options; (ii) the model matches observed bids and premiums of multidimensional options that integrate Ratchet, Asian, and Barrier characteristics; and (iii) our closed-form approximation allows for an analytical solution of the option’s greeks, which characterize the sensitivity to various risk factors.

Résumé :

A unified theory of estimation and inference is developed for an autoregressive process with root in (-∞, ∞) that includes the stationary, local-to-unity, explosive and all intermediate regions. The discontinuity of the limit distribution of the t-statistic outside the stationary region and its dependence on the distribution of the innovations in the explosive regions (-∞, -1) ∪ (1, ∞) are addressed simultaneously. A novel estimation procedure, based on a data-driven combination of a near-stationary and a mildly explosive artificially constructed instrument, delivers mixed-Gaussian limit theor

Résumé :

COVID-19 has created an unprecedented global health crisis that caused millions of infections and deaths worldwide. Many, however, argue that pre-existing social inequalities have led to inequalities in infection and death rates across social classes, with the most-deprived classes are worst hit. In this paper, we derive semi/non-parametric estimators of Health Concentration Curve (HC) that can quantify inequalities in COVID-19 infections and deaths and help identify the social classes that are most at risk of infection and dying from the virus. We express HC in terms of copula function that w

Résumé :

There is a growing recognition that offshore structures fundamentally distort the world map of foreign direct investment (FDI). This paper advances efforts to map the ultimate owners hidden in official data behind offshore or ‘phantom’ FDI by using a novel methodology to deconstruct the ultimate origins of FDI in the US, UK, France, Germany, Italy, Brazil, Russia, India, and China. In contrast to previous studies, this methodology unpicks distortions created by the offshore re-domiciliation of corporate groups at the parent level, in addition to subsidiary level, by determining the ‘true’ ulti

Résumé :

Contrary to the opinions expressed by many commentators, the recent price spike in agricultural commodities is a transitory phenomenon. Using projections from SIMPLE – a global model of the farm and food system – we argue that, in the long run, food prices will most likely resume their historical downward trend. We begin with an evaluation of the historical period 1961 to 2006 wherein the growth in agricultural productivity outpaced that of global crop demand, the latter being fueled by rising population and incomes. As a consequence, we observed a historical decline in global crop prices, whi

Experimental work was conducted on two girth welds in large diameter steel pipes. By a proper selection of welding consumables, yield strength mismatch was obtained from 5 to 12% undermatching and 45% overmatching. The girth welds were non-destructively tested using the time of flight diffraction technique by three NDE companies. The verification of the detection and sizing capabilities of TOFD inspection techniques has shown that the performance levels varied widely. This finding confirms the need to validate the NDE techniques. Tensile specimens, Charpy and CTOD specimens, and curved wide pl
