Remaining Useful Life Prediction Using Elliptical Basis Function Network And Markov Chain

Yi Yu, Lin Ma, Yong Sun, Yuantong Gu
2010 Zenodo  
The estimated external and the unknown internal covariates constitute an incomplete covariate set which are then used and analyzed by the EBF network to provide survival information of the asset.  ...  No explicit extrapolation is needed for internal covariates while a Markov chain is constructed to represent the evolution of external covariates in the study.  ...  ACKNOWLEDGMENT This paper was developed within the CRC for Infrastructure and Engineering Asset Management, established and supported under the Australian Government's Cooperative Research Centre Program  ...

2021 Anthropologia integra  
One of the potential practical applications of our program is to test whether an evaluated child with incomplete growth (e.g., at age 4, 8, or 13) is growing "normally" or should be considered abnormal  ...  Currently, the application allows computing of the FPCA model and its derived estimates for one specified longitudinal series of body height measurements of an individua -only one case (child) can now  ...  The main object of his studies is the use of static and dynamic features of the human body in forensic anthropology, especially in virtual environment.  ...

Dealing with uncertainties in environmental burden of disease assessment

Anne B Knol, Arthur C Petersen, Jeroen P van der Sluijs, Erik Lebret
2009 Environmental Health  
Environmental burden of disease estimates enable policy makers to evaluate, compare and prioritize dissimilar environmental health problems or interventions.  ...  We propose the use of an uncertainty typology to identify and characterize uncertainties.  ...  Furthermore, we are grateful to Bert Brunekreef, as well as to the reviewers, for useful comments and suggestions.  ...

Xihe: A 3D Vision-based Lighting Estimation Framework for Mobile Augmented Reality [article]

Yiqin Zhao, Tian Guo
2021 arXiv   pre-print
However, in practice, estimating omnidirectional lighting can be challenging due to limitations such as partial panoramas of the rendering positions, and the inherent environment lighting and mobile user  ...  Centering the key idea of 3D vision, in this work, we design an edge-assisted framework called Xihe to provide mobile AR applications the ability to obtain accurate omnidirectional lighting estimation  ...  We use Xihe's session recorder to capture recordings when the user is interacting with our reference AR application in an indoor environment.  ...

The proposed approach, based on a frequency domain description of an input design, as in earlier works on ex- periment design for lumped parameter systems, is shown to be fruitful.  ...  With this method it is possible to design classes of admissible fil- ters, including filters of order higher than the order of the equation specifying the process.  ... 

Adaptive item-based learning environments based on the item response theory: possibilities and challenges

K. Wauters, P. Desmet, W. Van den Noortgate
2010 Journal of Computer Assisted Learning  
In order to make learning environments more efficient, researchers have been exploring the possibility of an automatic adaptation of the learning environment to the learner or the context.  ...  Therefore, we discussed the two main challenges associated with IRT application in such learning environments: the challenge of the data set and the challenge of the algorithm.  ...  In this paper, we wanted to identify associated problems and suggested solutions based on the literature on testing and learning environments, whether they were IRT-based or not.  ...

Interspecific-Competition Strongly Constrains Species-Richness and Species-Abundance Evenness in a Tropical Marine Molluscan Community Inhabiting Caulerpa Beds, as Compared to Coral-Reefs

Jean Béguinot
2021 Asian Journal of Environment & Ecology  
In this perspective, we quantify and compare how species-richness accommodation proceeds in two major taxonomic groups, Bivalves and Gastropods respectively, both belonging to a same molluscan community  ...  So that, concretely, each community requires a specific analysis, in order to disentangle and quantify the respective contributions of the niche-diversification and the intensity of interspecific-competition  ...  The second possibility can be exploited, here, with a same environment (Caulerpa beds) and two different kinds of communities in this same environment (Gastropods and Bivalves groups).  ...

Addressing scope of inference for global genetic evaluation of livestock

Robert John Tempelman
2010 Revista Brasileira de Zootecnia  
Management systems and environments have and will continue to change; hence, it is vital that genetic evaluations are as robust and scope-appropriate as is possible in order to optimize animal adaptation  ...  For example, estimating haplotype effects from the data of a single reference population does not bode well for the use of WGS in other diverse environments since the scope of inference is too narrow;  ...  ") and the rate of divergence in genetic merit with improving environments.  ...

2015 Journal of Occupational and Environmental Hygiene  
As the scientific basis for uncertainty factor application has improved, default uncertainty factors are now used only in the absence of chemical-specific data, and the trend is to replace them with chemical-specific  ...  Five key uncertainties that are often examined include interspecies variability in response when extrapolating from animal studies to humans, response variability in humans, uncertainty in estimating a  ...  ACKNOWLEDGMENTS T he authors thank the following for their helpful comments and suggestions on earlier drafts: Ed Sargent, Linda Schenk, Paul Schulte, and Christine Sofge.  ...
