Automatic detection of defective crankshafts by image analysis and supervised classification
(2019)[Abstract]: A crankshaft is a mechanical component of an engine that performs a conversion of an alternative movement of a piston in a rotational motion of a shaft. It is a critical part and one of the most expensive of ... -
Kernel distribution estimation for grouped data
(Institut d'Estadística de Catalunya, 2019)[Abstract]: Interval-grouped data appear when the observations are not obtained in continuous time, but monitored in periodical time instants. In this framework, a nonparametric kernel distribution esti- mator is proposed ... -
Poisson mixed models for predicting number of fires
(CSIRO, 2019-03)[Abstract]: Wildfires are considered one of the main causes of forest destruction. In recent years, the number of forest fires and burned area in Mediterranean regions have increased. This problem particularly affects ... -
DNA methylation screening after roux-en Y gastric bypass reveals the epigenetic signature stems from genes related to the surgery per se
(Springer Nature, 2019-05-27)[Abstract] Background/objectives: Obesity has been associated with gene methylation regulation. Recent studies have shown that epigenetic signature plays a role in metabolic homeostasis after Roux-en Y gastric bypass ... -
Distributed classification based on distances between probability distributions in feature space
(Elsevier, 2019-09)[Abstract]: We consider a distributed framework where training and test samples drawn from the same distribution are available, with the training instances spread across disjoint nodes. In this setting, a novel learning ... -
Analysis of interval‐grouped data in weed science: The binnednp Rcpp package
(John Wiley & Sons Ltd., 2019-09-13)[Abstract] Weed scientists are usually interested in the study of the distribution and density functions of the random variable that relates weed emergence with environmental indices like the hydrothermal time (HTT). ... -
On egalitarian values for cooperative games with a priori unions
(Springer & Spanish Society of Statistics and Operations Research, 2020)[Abstract]: In this paper, we extend the equal division and the equal surplus division values for transferable utility cooperative games to the more general setup of transferable utility cooperative games with a priori ... -
Sharing delay costs in stochastic scheduling problems with delays
(Springer, 2020)[Abstract]: An important problem in project management is determining ways to distribute amongst activities the costs that are incurred when a project is delayed because some activities end later than expected. In this ... -
ProjectManagement: an R Package for Managing Projects
(R Foundation for Statistical Computing, 2020)[Abstract]:Project management is an important body of knowledge and practices that comprises the planning, organisation and control of resources to achieve one or more pre-determined objectives. In this paper, we introduce ... -
A goodness-of-fit test for regression models with spatially correlated errors
(2020)The problem of assessing a parametric regression model in the presence of spatial correlation is addressed in this work. For that purpose, a goodness-of-fit test based on a -distance comparing a parametric and nonparametric ... -
Constructing a Control Chart Using Functional Data
(MDPI AG, 2020-01-02)[Abstract] This study proposes a control chart based on functional data to detect anomalies and estimate the normal output of industrial processes and services such as those related to the energy efficiency domain. Companies ... -
Inter-and Intra-Examiner Reliability of Supraspinatus Muscle Tendon Palpation: A Cross-Sectional Study by Ultrasonography
(Kauno Medicinos Universitetas,Kaunas University of Medicine, 2020-02-18)[Abstract] Background and objectives: Palpation is an inherent and basic skill of health professionals—particularly manual therapists who base their diagnosis and treatment in a clinical environment. Many authors have ... -
Altered pathways in methylome and transcriptome longitudinal analysis of normal weight and bariatric surgery women
(NLM (Medline), 2020-04-15)[Abstract] DNA methylation could provide a link between environmental, genetic factors and weight control and can modify gene expression pattern. This study aimed to identify genes, which are differentially expressed and ... -
On benefits of cooperation under strategic power
(Springer, 2020-05)[Abstract]: We introduce a new model involving TU-games and exogenous structures. Specifically, we consider that each player in a population can choose an element in a strategy set and that, for every possible strategy ... -
Nonparametric covariate hypothesis tests for the cure rate in mixture cure models
(John Wiley & Sons, 2020-06)[Abstract]: In lifetime data, like cancer studies, there may be long term survivors, which lead to heavy censoring at the end of the follow-up period. Since a standard survival model is not appropriate to handle these data, ... -
How do early socioeconomic circumstances impact inflammatory trajectories? Findings from Generation XXI
(Elsevier, 2020-09)[Abstract]: Background: The association between socioeconomic position and markers of inflammation in adults, including C-reactive protein (CRP), is well-established. We hypothesized that children from families of ... -
Small area estimation of proportions under area-level compositional mixed models
(Springer Nature, 2020-09)[Abstract]: This paper introduces area-level compositional mixed models by applying transformations to a multivariate Fay–Herriot model. Small area estimators of the proportions of the categories of a classification variable ... -
Big-But-Biased Data Analytics for Air Quality
(MDPI AG, 2020-09-22)[Abstract] Air pollution is one of the big concerns for smart cities. The problem of applying big data analytics to sampling bias in the context of urban air quality is studied in this paper. A nonparametric estimator ... -
A heuristic approach to the task planning problem in a home care business
(Springer, 2020-12)[Abstract]: In this paper, we study a task scheduling problem in a home care business. The company has a set of supervisors in charge of scheduling the caregivers’ weekly plans. This can be a time-consuming task due to the ... -
Outlier Detection for Multivariate Time Series: A Functional Data Approach ®
(Elsevier, 2021)[Abstract] A method for detecting outlier samples in a multivariate time series dataset is proposed. It is assumed that an outlying series is characterized by having been generated from a different process than those ...
