Serial factorial design

Biometrika, 1968
SUMMARY Serial factorial designs are designs for long-term experiments with one or more basic treatments repeated as separate factors every year. The designs are cyclic, with essentially the same structure in any period of successive years. For example, three rates of a single basic treatment (e.g.

Design, analysis and presentation of factorial randomised controlled trials [PDF]

BMC Medical Research Methodology, 2003
Background The evaluation of more than one intervention in the same randomised controlled trial can be achieved using a parallel group design. However this requires increased sample size and can be inefficient, especially if there is also interest in ...

Aplicação da metodologia de planejamento fatorial e análise de superfícies de resposta para otimização da fermentação alcoólica Application of the factorial design and response surface methodology for optimization of alcoholic fermentation

Química Nova, 2008
In the present work, the influence of the amount of nitrogen and phosphorus and degrees Brix on the yield and productivity of alcoholic fermentation has been evaluated. The methodology used was factorial design and response surface analysis.

ZAMSTAR, The Zambia South Africa TB and HIV Reduction Study: design of a 2 x 2 factorial community randomized trial. [PDF]

, 2008
BACKGROUND: TB and HIV form a deadly synergy in much of the developing world, especially Africa. Interventions to reduce the impact of these diseases at community level are urgently needed.

Influência do material e volume do porta-amostra na determinação termogravimétrica do teor de cinzas em mel Influence of material and volume of the sample holder on the thermogravimetric determination of ash contents in honey

Química Nova, 2005
The results suggest that the two variables studied are significant and that they may be independently optimized. The material of the sample holder interferes with the incineration process only due to the amount of heat transfered.

Aplicação de planejamento fatorial a protocolo de extração e fixação de sulfetos volatilizáveis por acidificação (SVA) em amostras de sedimento Factorial design used on the extraction and fixation of acid volatile sulfides (AVS) from sediment samples

Química Nova, 2009
The AVS is defined operationally as acid volatile sulfide, which is a controlling phase on the partition of some metallic species in sediments. A Factorial design was evaluated by means of 16 experiments and using four variables: temperature, extraction ...

Minimum Aberration Split-Plot Designs Focusing on the Whole Plot Factors

Mathematics, 2022
In some experiments, the levels of some factors are difficult to change; then fractional factorial split-plot (FFSP) designs are suitable for selection.

An experimental evaluation of a loop versus a reference design for two-channel microarrays [PDF]

, 2004
Motivation: Despite theoretical arguments that socalled "loop designs" of two-channel DNA microarray experiments are more efficient, biologists keep on using "reference designs".
