Collective sampling of environmental features under limited sampling budget Universiteit Gent
Exploration of an unknown environment is one of the most prominent tasks for multi-robot systems. In this paper, we focus on the specific problem of how a swarm of simulated robots can collectively sample a particular environment feature. We propose an energy-efficient approach for collective sampling, in which we aim to optimize the statistical quality of the collective sample while each robot is restricted in the number of samples it can take. ...
STtech: sampling and transport techniques for Aedes eggs during a sampling campaign in a low-resource setting Instituut voor Tropische Geneeskunde
Container-breeding Aedes spp. (Diptera: Culicidae) mosquitoes can be surveilled at low cost using ovitraps. Hence, this method is a preferred monitoring approach of dengue vectors in low-resource settings. The ovitraps consist of a cup filled with water and an oviposition substrate for female mosquitoes. The attractiveness of the substrates for female mosquitoes can greatly differ due to differences in texture, color, and smell of the ...
Passive sampling reversed: coupling passive field sampling with passive lab dosing to assess the ecotoxicity of mixtures present in the marine environment Universiteit Gent
A mixed-method investigation into measurement reactivity to the experience sampling method: The role of sampling protocol and individual characteristics KU Leuven
Since the introduction of the experience sampling method (ESM), there have been concerns that the repeated assessments typically related to this method may alter the behavior, thoughts, or feelings of participants. Previous studies have offered mixed results with some studies reporting reactive changes, while others failed to find such effects. Our aim was to investigate under which circumstances ESM induces reactive effects. Students (N = 151) ...
Face mask sampling (FMS) for tuberculosis shows lower diagnostic sensitivity than sputum sampling in Guinea Instituut voor Tropische Geneeskunde
BACKGROUND: Pulmonary tuberculosis (PTB) diagnosis relies on sputum examination, a challenge in sputum-scarce patients. Alternative non-invasive sampling methods such as face mask sampling (FMS) have been proposed.
OBJECTIVE: To evaluate the value of FMS for PTB diagnosis by assessing its agreement with sputum samples processed by GeneXpert MTB/RIF (Ultra)(Xpert) testing, and describe FMS sensitivity and specificity.
METHODS: ...
The effects of sampling frequency and questionnaire length on perceived burden, compliance, and careless responding in experience sampling data in a student population KU Leuven
Currently, little is known about the association between assessment intensity, burden, data quantity, and data quality in experience sampling method (ESM) studies. Researchers therefore have insufficient information to make informed decisions about the design of their ESM study. Our aim was to investigate the effects of different sampling frequencies and questionnaire lengths on burden, compliance, and careless responding. Students (n = 163) ...
Perceptions of self sampling and urine sampling versus traditional pap smear in rural settings of Cuenca Ecuador Universiteit Antwerpen
Background: Cervical cancer screening has demonstrated high effectiveness reducing cervical cancer mortality worldwide, however there is still a high rate of under screened women. Pap smear technique is often considered an uncomfortable examination technique that can reduce uptake of the examination. This study explores the perceptions of self sampling and urine sampling versus traditional pap smear in rural settings of Cuenca Ecuador. Methods A ...
Monte-Carlo based uncertainty analysis: Sampling efficiency and sampling convergence KU Leuven
Monte Carlo analysis has become nearly ubiquitous since its introduction, now over 65 years ago. It is an important tool in many assessments of the reliability and robustness of systems, structures or solutions. As the deterministic core simulation can be lengthy, the computational costs of Monte Carlo can be a limiting factor. To reduce that computational expense as much as possible, sampling efficiency and convergence for Monte Carlo are ...
