Moments of Conditional Sojourn Times in Finite Capacity M/M/1/N-PS Processor Sharing Queues [PDF]
IEEE Communications Letters, 2012 Moments of sojourn times conditioned on the length of an admitted job are derived for a finite capacity M/M/1/N-PS processor sharing queue. The mean conditional sojourn time is given in closed form whereas an expression is provided for the conditional ...

Sojourn times and the fragility index [PDF]
Stochastic Processes and their Applications, 2011 We investigate the sojourn time above a high threshold of a continuous stochastic process Y = ( Y t ) t ∈ [ 0 , 1 ] . It turns out that the limit, as the threshold increases, of the expected sojourn time given that it is positive, exists if the copula ...

On the rate of convergence for central limit theorems of sojourn times of Gaussian fields [PDF]
Stochastic Processes and Their Applications, 2013 The aim of this paper is to control the rate of convergence for central limit theorems of sojourn times of Gaussian fields in both cases: the fixed and the moving level. Our main tools are the Malliavin calculus and the Stein method, developed by Nualart,

Context-Aware Beam Selection for IRS-Assisted mmWave V2I Communications [PDF]
SensorsMillimeter wave (mmWave) technology, with its ultra-high bandwidth and low latency, holds significant promise for vehicle-to-everything (V2X) communications. However, it faces challenges such as high propagation losses and limited coverage in dense urban

Multistate markov model analysis of metabolic syndrome progression in a community-based longitudinal cohort study [PDF]
Diabetology & Metabolic SyndromeBackground Metabolic syndrome (MetS) is a cluster of metabolic abnormalities that are strongly associated with cardiovascular disease and diabetes. However, there is limited evidence on how MetS develops from individual metabolic abnormalities.

Estimation of semi-Markov multi-state models: a comparison of the sojourn times and transition intensities approaches [PDF]
The International Journal of Biostatistics, 2020 Semi-Markov models are widely used for survival analysis and reliability analysis. In general, there are two competing parameterizations and each entails its own interpretation and inference properties.

On the sojourn time of a generalized Brownian meander [PDF]
Statistics & Probability Letters, 2021 In this paper we study the sojourn time on the positive half-line up to time $ t $ of a drifted Brownian motion with starting point $ u $ and subject to the condition that $ \min_{ 0\leq z \leq l} B(z)> v $, with $ u > v $. This process is a drifted Brownian meander up to time $ l $ and then evolves as a free Brownian motion. We also consider the

Renewal theory with fat-tailed distributed sojourn times: Typical versus rare [PDF]
Physical Review E, 2018 Renewal processes with heavy-tailed power law distributed sojourn times are commonly encountered in physical modelling and so typical fluctuations of observables of interest have been investigated in detail.
