We have searched for exclusive gammagamma production in proton-antiproton collisions at sqrt[s]=1.96 TeV, using 532 pb(-1) of integrated luminosity taken by the run II Collider Detector at Fermilab. The event signature requires two electromagnetic showers, each with transverse energy E(T)>5 GeV and pseudorapidity |eta|<1.0, with no other particles detected in the event. Three candidate events a...
During the period 24-25 July 2004, elevated convection produced rain totaling up to 5 inches across east-central Missouri. No rain was forecast by the 12 km Eta model over this area. The presence of two concurrent mesoscale convective systems rendered this event a particularly challenging one for numerical weather prediction. An analysis of the physical differences between the model forecast an...
and Conclusions This paper is concerned with the analysis of Event Trees where the branch point event causes are defined using Fault Tree structures. Attention is focussed on the non-trivial situation where there are dependencies amongst the branch point events. The dependencies are due to component failure events featuring in one or more of the fault trees. In these situations it is shown that...
In the present paper, nonlinear behavior of mass concrete simulated by smeared crack model is combined with Endurance Time Analysis (ETA) method for studying seismic response of arch dams. ETA is a time-history based dynamic pushover procedure in which special predesigned intensifying acceleration functions are used for analysis and estimation of structural responses in various performance leve...
This paper reviews the theoretical bases of the barrier modelling analysis, and introduces a novel approach for considering the barrier effects on the probability of the events through the event tree analysis. A structure for modelling barrier sets is developed. Using the techniques of the reliability analysis, an approach for calculating the effects of the barriers on the probability of events...
Human Reliability Analysis (HRA) has found application within a diverse set of engineering domains, but the methods used to apply HRA are often complicated, time-consuming, costly apply, specific particular (i.e., nuclear) applications, and not suitable for direct comparison amongst themselves.
 This paper proposes Factors Hazard Model (HFHM), which builds an method from tools Fault Tree (...
Introduction: Chemical industries often have risks for the environment and communities, due to the use of complex facilities and processes. Also, in the ammonia tanks, the probability of risk of explosion is high, owing to their specific characteristics. The aim of this study is to evaluate the risks of explosion scenario at the ammonia tank in the Kermanshah petrochemical complex Material and...
