Bearing Capacity of Unbonded Flexible Pipe Carcass with Corrosion Defects

open access: yesShiyou jixie, 2022
The innermost carcass of flexible pipe directly contacts with the transported medium,and corrosion occurs inevitably,which will affect the pressure bearing capacity of the pipeline.In order to investigate the influence of corrosion defects on the ...

Auditory learning of recurrent tone sequences is present in the newborn's brain

open access: yesNeuroImage, 2023
The seemingly effortless ability of our auditory system to rapidly detect new events in a dynamic environment is crucial for survival. Whether the underlying brain processes are innate is unknown.

Evaluating Variable Length Markov Chain Models for Analysis of User Web Navigation Sessions

open access: yes, 2006
Markov models have been widely used to represent and analyse user web navigation data. In previous work we have proposed a method to dynamically extend the order of a Markov chain model and a complimentary method for assessing the predictive power of ...

Ground Vehicle Tracking Using Context-Based Sojourn Time Dependent Markov Model and Pseudo-Measurement

open access: yesIEEE Access, 2020
Tracking maneuvering vehicles in complex dynamic environment is a challenging problem for advanced driver assistance system and autonomous driving systems. Most conventional vehicle tracking algorithms can not model the vehicle dynamic exactly because of

GAUSSIAN MIXTURE MODEL AND RJMCMC BASED RS IMAGE SEGMENTATION [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017
For the image segmentation method based on Gaussian Mixture Model (GMM), there are some problems: 1) The number of component was usually a fixed number, i.e., fixed class and 2) GMM is sensitive to image noise.

Examination of genome homogeneity in prokaryotes using genomic signatures. [PDF]

open access: yesPLoS ONE, 2009
BACKGROUND:DNA word frequencies, normalized for genomic AT content, are remarkably stable within prokaryotic genomes and are therefore said to reflect a "genomic signature." The genomic signatures can be used to phylogenetically classify organisms from ...

Efficient ticket routing by resolution sequence mining [PDF]

open access: yes, 2008
IT problem management calls for quick identification of resolvers to reported problems. The efficiency of this process highly depends on ticket routing—transferring problem ticket among various expert groups in search of the right resolver to the ticket.

An Online Continuous Human Action Recognition Algorithm Based on the Kinect Sensor

open access: yesSensors, 2016
Continuous human action recognition (CHAR) is more practical in human-robot interactions. In this paper, an online CHAR algorithm is proposed based on skeletal data extracted from RGB-D images captured by Kinect sensors. Each human action is modeled by a

Low-Rank Separated Representation Surrogates of High-Dimensional Stochastic Functions: Application in Bayesian Inference

open access: yes, 2013
This study introduces a non-intrusive approach in the context of low-rank separated representation to construct a surrogate of high-dimensional stochastic functions, e.g., PDEs/ODEs, in order to decrease the computational cost of Markov Chain Monte Carlo
