Adaptive Baseline Finder, a statistical data selection strategy to identify atmospheric CO2 baseline levels and its application to European elevated mountain stations [Discussion paper]

Description: This paper presents a novel statistical data selection method for CO2 measurements at elevated mountain measuring stations. It provides insights on how data processing techniques are critical for measurements and data analyses. By applying different methods on atmospheric CO2 of various mountain sta...

B-splines as a tool to solve constraints in non-hydrostatic forecast model

Description: Finite elements has been proven to be an useful tool to discretize the vertical coordinate in the hydrostatic forecast models allowing to define model variables in full levels so that no staggering is needed. In the non-hydrostatic case a constraint in the vertical operators appears (called C1) that...

Comparing cell viability and ethanol fermentation of the thermotolerant yeast Kluyveromyces marxianus and Saccharomyces cerevisiae on steam-exploded biomass treated with laccase

Description: In this study, the thermotolerant yeast Kluyveromyces marxianus CECT 10875 was compared to Saccharomyces cerevisae Ethanol Red for lignocellulosic ethanol production. For it, whole slurry from steam-exploded wheat straw was used as raw material, and two process configurations, simultaneous saccha...

Robust Principal Component Analysis Based On Trimming Around Affine Subspaces

Description: Principal Component Analysis (PCA) is a widely used technique for reducing dimensionality of multivariate data. The principal component subspace is defined as the affine subspace of a given dimension d giving the best fit to the data. However, PCA suffers from a well-known lack of robustness. As a r...

A Fuzzy Approach to Robust Clusterwise Regression

Description: new robust fuzzy linear clustering method is proposed. We estimate coe cients of a linear regression model in each unknown cluster. Our method aims to achieve robustness by trimming a xed proportion of observations. Assignments to clusters are fuzzy: observations contribute to estimates in more tha...

Finding the Number of Groups in Model-Based Clustering via Constrained Likelihoods

Description: Deciding the number of clusters k is one of the most difficult problems in Cluster Analysis. For this purpose, complexity-penalized likelihood approaches have been introduced in model-based clustering, such as the well known BIC and ICL criteria. However, the classification/mixture likelihoods consi...

A Reweighting Approach to Robust Clustering

Description: An iteratively reweighted approach for robust clustering is presented in this work. The method is initialized with a very robust clustering partition based on an high trimming level. The initial partition is then refined to reduce the number of wrongly discarded observations and substantially increa...

The formation and rupture of oropharingeal membrane in the mouse embryo: The role of cell death

Description: Producción Científica , Se realiza un estudio histológico y ultraestructural de la formación y desaparición de la membrana orofaríngea (bucofaringea) durante el desarrollo embrionario del ratón. La membrana orofaríngea aparece en embriones de ratón de 5-7 somites, como una zona de aposición...

Robust constrained fuzzy clustering

Description: It is well-known that outliers and noisy data can be very harmful when applying clustering methods. Several fuzzy clustering methods which are able to handle the presence of noise have been proposed. In this work, we propose a robust clustering approach called F-TCLUST based on an “impartial” (i.e.,...
