a parallel hybrid system of hmm and gmm modeling techniques was implemented and used in a telephony speaker verification and identification system. spectral subtraction and weighted projection measure were used to render this system more robust against additional noise. cepstral mean subtraction method was also applied for the compensation of convolution noise due to transmission channel degrad...
State-transition modeling is an intuitive, flexible, and transparent approach of computer-based decision-analytic modeling including both Markov model cohort simulation and individual-based (first-order Monte Carlo) microsimulation. Conceptualizing a decision problem in terms of a set of (health) states and transitions among these states, state-transition modeling is one of the most widespread ...
OBJECTIVES The purpose of the study was to develop a population-based simulation model of osteoarthritis (OA) in Canada that can be used to quantify the future health and economic burden of OA under a range of scenarios for changes in the OA risk factors and treatments. In this article we describe the overall structure of the model, sources of data, derivation of key input parameters for the ep...
Abstract Based on microsimulation, this study analyses the performance and behavior of motorized vehicles at signalized intersection between railway line Ahmad Yani road-Jemursari road. For survey volume vehicles, is divided into four intersections with eight directions traffic movement one direction combined movement. Microsimulation was carried out using Vissim software nine parameters calibr...
In this study, for the first time, we model gasoline consumption behavior in Iran using the long-term memory model of the autoregressive fractionally integrated moving average and non-linear Markov-Switching regime change model. Initially, the long-term memory feature of the ARFIMA model is investigated using the data from 1927 to 2017. The results indicate that the time series studied has a lo...
JAMSIM (JAva MicroSIMulation) is an innovative synthesis of open source packages that provides an environment and set of features for the creation of dynamic discrete-time microsimulation models that are to be executed, manipulated and interrogated by non-technical, policy-oriented users. JAMSIM combines the leading open source statistical package R and one of the foremost agentbased modelling ...
OBJECTIVE The aim of this paper was to review and compare HIV vaccine cost-effectiveness analyses and describe the effects of uncertainty in model, methodology, and parameterization. METHODS We systematically searched MEDLINE (1985 through May 2016), EMBASE, the Tufts CEA Registry, and reference lists of articles following Cochrane guidelines and PRISMA reporting. Eligibility criteria include...
A candidate Variable Speed Limits Sign (VSLS) control algorithm was applied to an urban freeway in Toronto, Canada using microsimulation. The microsimulation model was combined with a categorical crash model to quantify the impacts of VSLS implementation on safety and traffic performance. The VSLS control strategy was developed as a practical algorithm that responded to real-time measures of tr...
