A Sub-Optimal Policy for Connection Admission Control Mechanism in Cognitive Radio Sensor Networks
International Journal of Information and Communication Technology Research, 2017 Satisfying the quality of service (QoS) is a crucial issue in cognitive radio sensor networks (CRSNs) due to the highly variable nature of cognitive radio channels.

A semi-Markov model for price returns
, 2011 We study the high frequency price dynamics of traded stocks by a model of returns using a semi-Markov approach. More precisely we assume that the intraday return are described by a discrete time homogeneous semi-Markov process and the overnight returns ...

A Semi-Markov Modulated Interest Rate Model
, 2012 In this paper we propose a semi-Markov modulated model of interest rates. We assume that the switching process is a semi-Markov process with finite state space E and the modulated process is a diffusive process.

Continuous-Observation Partially Observable Semi-Markov Decision Processes for Machine Maintenance [PDF]
IEEE Transactions on Reliability, 2017 Partially observable semi-Markov decision processes (POSMDPs) provide a rich framework for planning under both state transition uncertainty and observation uncertainty. In this paper, we widen the literature on POSMDP by studying discrete-state, discrete-action yet continuous-observation POSMDPs.

Asymptotic Expansions for Stationary Distributions of Perturbed Semi-Markov Processes
, 2016 New algorithms for computing of asymptotic expansions for stationary distributions of nonlinearly perturbed semi-Markov processes are presented. The algorithms are based on special techniques of sequential phase space reduction, which can be applied to ...

Self-Optimizing and Pareto-Optimal Policies in General Environments based on Bayes-Mixtures
, 2002 The problem of making sequential decisions in unknown probabilistic environments is studied. In cycle $t$ action $y_t$ results in perception $x_t$ and reward $r_t$, where all quantities in general may depend on the complete history.

Managing Wind Power Generation via Indexed Semi-Markov Model and Copula
Energies, 2020 Because of the stochastic nature of wind turbines, the output power management of wind power generation (WPG) is a fundamental challenge for the integration of wind energy systems into either power systems or microgrids (i.e., isolated systems consisting
