A4Learning: a case study to improve the user performance Alumni Alike Activity Analytics to self-assess personal progress
Students usually find difficult to estimate if their effort in learning courses finds the instructor expectations. They tend to estimate "if they are doing right" by comparing themselves with peers, but this is difficult ...
Standard addition calibration: Is it enough for an analytical result estimation?. Spectrophotometric experiments for analyte quantitation in real samples
(Research Trends, 2021-12)
Analytical method validation is the first step for quantitative analysis, and both validation and quantitation are usual and fundamental tasks in analytical work; hence it is extremely important to perform them in the most ...
Alternative admissible biased estimators
(Institute of Electrical and Electronics Engineers, 2013)
In this work, a biased estimator obtained from an affine transformation of an unbiased estimator will be analyzed. In particular, the method proposed by Y. C. Eldar will be studied, and alternative approaches will be ...
Optimality of the maximum likelihood estimator in astrometry
(EDP Sciences, 2018)
Context. Astrometry relies on the precise measurement of positions and motions of celestial objects. Driven by the ever-increasing
accuracy of astrometric measurements, it is important to critically assess the maximum ...
A new and consistent parameter for measuring the quality of multivariate analytical methods: Generalized analytical sensitivity
(Elsevier Science, 2016-08)
Generalized analytical sensitivity (γ) is proposed as a new figure of merit, which can be estimated from a multivariate calibration data set. It can be confidently applied to compare different calibration methodologies, ...
A Visual Analytics Method for Score Estimation in Learning Courses
The provision of awareness is a well-known method for fostering students' self-reflection, a metacognitive skill often related to academic success and considered one of the key skills of the 21st century. Although the ...
Estimation of chlorophyll-a concentration from optimizing a semi-analytical algorithm in productive inland waters
(2018-02-01)
The high nutrient concentrations coming from non-point and point pollution have been linked to algae blooms, especially in hydroelectric plant reservoirs, due to higher residence time compared to rivers. The monitoring of ...
Recent advances in analytical figures of merit: Heteroscedasticity strikes back
(Royal Society of Chemistry, 2017-02)
With a growing number of analytical methodologies incorporating multivariate calibration models, the development of suitable estimators of their analytical figures of merit is playing an important role in modern analytical ...
