Assessing nitrogen fertilizer response of coastal Douglas-fir in the Pacific Northwest using a paired-tree experimental design

Forest Ecology and Management, 2014
Abstract Nitrogen is the nutrient most limiting growth of coastal Douglas-fir of the Pacific Northwest and, accordingly, urea fertilization has been applied through the region to improve Douglas-fir growth. While factors affecting fertilizer response have been studied for years, changing management techniques and improved genetics warrant new studies

Permutation Methods for the Analysis of Matched-Pairs Experimental Designs

Psychological Reports, 2003
The Fisher-Pitman and powers of ranks permutation tests are shown to provide substantial resistance to extreme values when compared with the conventional t test for analyzing matched-pairs experimental designs.

Efficient experimental design for binary matched pairs data

Statistics in Medicine, 2009
AbstractThe analysis of data from matched pairs binary experiments, often performed with McNemar's test, presents a unique experimental design challenge in dealing with the effect of the discordance probability, p. Most approaches for determining size and power use point estimates or maximization, but this fails to account for the considerable ...

Experimental analysis of differential pairs designed with line tunnel FET devices

2017 IEEE SOI-3D-Subthreshold Microelectronics Technology Unified Conference (S3S), 2017
The aim of this work is to study, for the first time, the behavior of differential pair circuits designed with Line TFETs and compare the suitability of this technology with alternatives such as FinFETs and Point TFETs. The first part highlights experimental characteristics of individual Line TFET transistors, which present similar transconductance and

Experimental design and evaluation of differential-skew dependence on differential-pair orientation

2015 10th International Microsystems, Packaging, Assembly and Circuits Technology Conference (IMPACT), 2015
An experiment was conducted to evaluate the dependence of differential skew on the differential-pair orientations relative to the filling yarn of the glass fabrics of a printed circuit board. The level of differential skew of a differential pair is evaluated by measuring the phase difference of the two traces that forms a differential pair.

Experimental Designs Balanced for Pairs of Residual Effect

Australian Journal of Scientific Research Series A: Physical Sciences, 1950
When different treatments are applied In succession to the same unit of experimental material, it is necessary to consider the residual effects of preceding treatments on the present treatment. To facilitate the interpretation of the results of such experiments, balanced designs have been developed.

Design of an Experimental Setup for Freely Positionable Coil Pairs for Transcutaneous Energy Transfer Systems

2018 EMF-Med 1st World Conference on Biomedical Applications of Electromagnetic Fields (EMF-Med), 2018
Mechanical circulatory support systems (MCSS), such as the left ventricular assist device (LVAD), still employ percutaneous drive-lines for the power supply of implanted components. Transcutaneous energy transfer (TET) offers the possibility to reduce drive-line related infections, but also improve patients’ every day life.

Experimental design and the control of error: II. Within-groups related design and matched pairs design

1981
So far we have presented exclusively the advantages of using different rather than the same people for all the experimental conditions.

Optimization of polymeric triiodide membrane electrode based on clozapine–triiodide ion-pair using experimental design

Talanta, 2008
Central composite design (CCD) and response surface methodology (RSM) were developed as experimental strategies for modeling and optimization of the influence of some variables on the performance of a new PVC membrane triiodide ion-selective electrode. This triiodide sensor is based on triiodide-clozapine ion-pair complexation.

Experimental design for the rapid selection of separation conditions for methyl and propyl parahydroxybenzoate, phenylephrine hydrochloride and chlorphenamine maleate by ion-pair liquid chromatography

Journal of Pharmaceutical and Biomedical Analysis, 1994
Methyl and propyl parahydroxybenzoate (MPHB, PPHB), phenylephrine hydrochloride (PE) and chlorphenamine maleate (CPM) are often combined as ingredients in cough-syrups. Due to distinct chemical structures, pKa values among other chemical properties are different.
