On imputation for planned missing data in context questionnaires using plausible values: a comparison of three designs

open access: yesLarge-scale Assessments in Education, 2018
Background This paper extends a recent study by Kaplan and Su (J Educ Behav Stat 41: 51–80, 2016) examining the problem of matrix sampling of context questionnaire scales with respect to the generation of plausible values of cognitive outcomes in large ...

A Note on the Balanced Incomplete Block Designs

open access: yesThe Annals of Mathematical Statistics, 1956
It is a well-known property of the BIB design that all treatment effects are estimated with the same accuracy, i.e., that the variances of the estimates of the treatment effects are all equal and their covariances are also all equal. We show that the converse is also true. If the estimates of the treatment effects in an incomplete block design all have

An adaptable implementation package targeting evidence-based indicators in primary care: A pragmatic cluster-randomised evaluation.

open access: yesPLoS Medicine, 2020
BackgroundIn primary care, multiple priorities and system pressures make closing the gap between evidence and practice challenging. Most implementation studies focus on single conditions, limiting generalisability. We compared an adaptable implementation

On the Photonic Implementation of Universal Quantum Gates, Bell States Preparation Circuit, Quantum Relay and Quantum LDPC Encoders and Decoders

open access: yesIEEE Photonics Journal, 2010
We show that any family of universal quantum gates can be implemented based on a single optical hybrid/Mach-Zehnder interferometer (MZI)/directional coupler (DC) and either a highly nonlinear optical fiber or a tap coupler with an avalanche photodiode ...

Optimal and efficient crossover designs for comparing test treatments with a control treatment

open access: yes, 2005
This paper deals exclusively with crossover designs for the purpose of comparing t test treatments with a control treatment when the number of periods is no larger than t+1. Among other results it specifies sufficient conditions for a crossover design to

EXPLORATION OF FINITE GROUP APPROACH IN BALANCED INCOMPLETE BLOCK DESIGN

open access: yesAcademy Journal of Science and Engineering
The development of block designs continues to be an unresolved challenge in combinatorial design, with several forms, the most notable being the balanced incomplete block designs (BIBDs).

ON D-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2015
The paper deals with the problem of determining the chemical balance weighing designs satisfying the criterion of D-optimality under assumption that the measurement errors are equal correlated and they have the same variances.
