A key criterion in the design of high-speed networks is the probability that the buffer content exceeds a given threshold. We consider n independent identical traffic sources modelled as point processes, which are fed into a link with speed proportional to n. Under fairly general assumptions on the input processes we show that the steady state probability of the buffer content exceeding a thres...

In various industries benzene is used for cleaning, stain removal, and dilution and as an adhesive. The petrochemical industry uses benzene as a raw material for styrene, alkyl benzene, and caprolactam. Moreover, aromatic compounds are added to gasoline as a substitute for alkyl lead compounds. Although atmospheric lead pollution is reduced, the concentration of benzene released into the air is...

It is not clear whether or not recreational runners can recover aerobic fitness and performance within one week after marathon running. This study aimed to investigate the effects of running a marathon race on aerobic fitness and performance one week later. Eleven recreational runners (six men, five women) completed the race in 3 h 36 min 20 s ± 41 min 34 s (mean ± standard deviation). Before a...

The real time evolution of non-equilibrium expectation values with soft length scales ∼ k−1 > (eT )−1 is solved in hot scalar electrodynamics, with a view towards understanding relaxational phenomena in the QGP and the electroweak plasma. We find that the gauge invariant non-equilibrium expectation values relax via power laws to asymptotic amplitudes that are determined by the quasiparticle pol...

The clusters of up spins of a two-dimensional Ising ferromagnet undergo a second order percolative transition at temperatures above the Curie point. We show that in the scaling limit the percolation threshold is described by an integrable field theory and identify the nonperturbative mechanism which allows the percolative transition in absence of thermodynamic singularities. The analysis is ext...

The real time evolution of field condensates with soft length scales ∼ k−1 > (eT )−1 is solved in hot scalar electrodynamics. We rederive the HTL effective action using the techniques of non-equilibrium field theory for small amplitude condensates. We find that transverse gauge invariant condensates relax as 1/t2 and longitudinal condensates associated with plasmon (charge density) excitations ...

BACKGROUND Biomechanical, psychosocial and individual risk factors for low back disorder have been studied extensively however few researchers have examined all three risk factors. The objective of this was to develop a low back disorder risk model in furniture distribution workers using biomechanical, psychosocial and individual risk factors. METHODS This was a prospective study with a six m...

In this paper we consider digital images for which the pixels values are given by a sequence of independent and identically distributed variables within an observation window. We proceed to construction unbiased estimator perimeter without border effects. The study first second moments allows prove auto-normalised asymptotic normality results with explicit covariance matrix consistently estimat...

Constant temperature and pressure molecular-dynamics simulations in conjunction with constant pressure and enthalpy simulations, designed to examine the threshold behavior in laser ablation, demonstrate that the rate of homogeneous nucleation (explosive boiling) increases sharply in a very narrow temperature range at approximately 90% of the critical temperature. Moreover, the homogeneous nucle...
