The effective sample size for multivariate spatial processes with an application to soil contamination
(2021)
Effective sample size accounts for the equivalent number of independent observations contained in a sample of correlated data. This notion has been widely studied in the context of univariate spatial variables. In that ...
Storage strategies and processing of bovine milk samples for pregnancy-associated glycoproteins detection test
(Taylor & Francis As, 2017-01-01)
Three experiments were performed to test if the time and storage conditions of milk samples, the preheating of samples in a water bath, as well as the carryover effect in laboratory analysis equipment could affect the ...
Effect of sample conditioning on the water absorption of concrete
(ELSEVIER SCI LTD, 2011)
ASTM C1585 is commonly used to determine the absorption and rate of absorption of water in unsaturated hydraulic cement concretes. Unfortunately, a wide range of relative humidities can exist in the samples after this ...
Effects of sampling completeness on the structure of plant-pollinator networks
(Wiley, 2012)
Plant-animal interaction networks provide important information on community organization. One of the most critical assumptions of network analysis is that the observed interaction patterns constitute an adequate sample ...
An empirical examination of respondent driven sampling design effects among HIV risk groups from studies conducted around the world
(Springer, 2013)
For studies using respondent driven sampling (RDS), the current practice of collecting a sample twice as large as that used in simple random sampling (SRS) (i.e. design effect of 2.00) may not be sufficient. This paper ...
Analysis of pesticides in food and environmental samples by enzyme-linked immunosorbent assays
(Elsevier B.V., 1998-02-01)
Enzyme-linked immunosorbent assays (ELISAs) are the most extensively studied types of immunoassay and their application in pesticide residue monitoring is an area with enormous potential for growth. In comparison with ...
Optimistic Motion Planning Using Recursive Sub- Sampling: A New Approach to Sampling-Based Motion Planning
Sampling-based motion planning in the field of robot motion planning has provided an effective approach to finding path for even high dimensional configuration space and with the motivation from the concepts of sampling ...
New passive sampling device for effective monitoring of pesticides in water
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE QUÍMICAUFMG, 2019)
The T2 chart with mixed samples to control bivariate autocorrelated processes
(2016-06-02)
In this paper, we propose the use of the T2 chart with the mixed sampling strategy (MS) to monitor the mean vector of bivariate processes with observations that fit to a first-order vector autoregressive model. With the ...
Interactions among resource partitioning, sampling effect, and facilitation on the biodiversity effect: A modeling approach
(Springer, 2014-01)
Resource partitioning, facilitation, and sampling effect are the three mechanisms behind the biodiversity effect, which is depicted usually as the effect of plant-species richness on aboveground net primary production. ...
