On high-dimensional sign tests

, 2016
Sign tests are among the most successful procedures in multivariate nonparametric statistics. In this paper, we consider several testing problems in multivariate analysis, directional statistics and multivariate time series analysis, and we show that ...

Optimal and fast detection of spatial clusters with scan statistics [PDF]

, 2010
We consider the detection of multivariate spatial clusters in the Bernoulli model with $N$ locations, where the design distribution has weakly dependent marginals.

Canonical correlation between clogging agents and performance of drippers operating with aquaculture effluents [PDF]

Revista Brasileira de Engenharia Agrícola e Ambiental
The canonical correlation is used to correlate groups of distinct variables. The objective of this study was to use canonical correlation analysis to evaluate the interaction between water quality attributes clogging-causing and the hydraulic performance

Integrated Sensor System for Condition Monitoring of Electromechanical Cylinders

Proceedings, 2017
In this work, a sensor system mechanically integrated in an electromechanical cylinder is presented with the goal of measuring relevant quantities for condition monitoring. The system monitors those parts of the cylinder which are mainly affected by wear

MERCURY IN THE SEDIMENT OF PELOTAS RIVER BASIN, BRAZIL [PDF]

Engenharia Agrícola, 2018
Many studies have determined the concentration of trace elements in river sediments in Brazil. Notwithstanding, mercury assessments are scarce, especially because of exclusive extraction techniques and expensive analysis techniques.

Multi-tract multi-symptom relationships in pediatric concussion

eLife, 2022
Background: The heterogeneity of white matter damage and symptoms in concussion has been identified as a major obstacle to therapeutic innovation. In contrast, most diffusion MRI (dMRI) studies on concussion have traditionally relied on group-comparison ...

A Comparison of Different Statistics for Detecting Multiplicative Faults in Multivariate Statistics-Based Fault Detection Approaches

IEEE Access, 2018
The explosion of different fault detection (FD) statistics in multivariate statistics-based FD approaches has meant that the practitioner is faced with the unenviable job of determining which to use in a given circumstance.

The relationship between symptom burden and systemic inflammation differs between male and female athletes following concussion

BMC Immunology, 2020
Background Inflammation appears to be an important component of concussion pathophysiology. However, its relationship to symptom burden is unclear. Therefore, the purpose of this study was to evaluate the relationship between symptoms and inflammatory ...
