Monitoring the process mean with an ATTRIVAR chart
(2020-01-01)
In this article, we propose an ATTRIVAR chart to control the process mean. With the ATTRIVAR chart, the sampling is performed in two stages, collecting attribute and variable sample data from the same sample (attribute ...
Inspecting the cepheid distance ladder: the Hubble space telescope distance to the SN Ia host Galaxy NGC 5584
(IOP Publishing, 2021)
The current tension between the direct and the early-universe measurements of the Hubble constant, H0, requires
detailed scrutiny of all the data and methods used in the studies on both sides of the debate. The Cepheids ...
Inspecting the Cepheid parallax of pulsation using Gaia EDR3 parallaxes Projection factor and period-luminosity and period-radius relations
(EDP, 2021)
Context. As primary anchors of the distance scale, Cepheid stars play a crucial role in our understanding of the distance scale of
the Universe because of their period-luminosity relation. Determining precise and consistent ...
Monitoring the covariance matrix of bivariate processes with the DVMAX control charts
(2022-01-01)
Two versions of Phase II attribute+variable (DVMAX) control charts are investigated for monitoring the covariance matrix (Formula presented.) of bivariate processes. Monitoring always starts with an attribute chart employing ...

Different approaches to characterize artificial breeding sites of Aedes aegypti using generalized linear mixed models
(BioMed Central, 2020-07)
Background: As no globally accepted dengue vaccines or specific antiviral therapies are currently available, controlling breeding sites of Aedes aegypti is a target to prevent dengue outbreaks. The present study aimed to ...
Exocomets: A spectroscopic survey
(European Southern Observatory, 2020)
Context. While exoplanets are now routinely detected, the detection of small bodies in extrasolar systems remains challenging. Since the discovery of sporadic events interpreted as exocomets (Falling Evaporating Bodies) ...
