Abstract: In this paper, a combined use of dimensional analysis (DA) and statistical design of experiments (DOE) is proposed for a hydrodynamics experiment where there are a large number of variables. While DA is well-known, DOE is still unfamiliar to most ocean engineers although it has been shown to be extremely useful in many engineering applications. To illustrate the method, a study concer...

Purpose: To improve the production of a novel exopolysaccharide (EPS) by Bacillus mucilaginosus CGMCC5766. Methods: The culture medium for production of EPS was optimized using statistical experiment design. Sucrose, CaCO3 and K2HPO4 were found to be the key factors based on the results obtained from Plackett–Burman experimental design. The optimal concentration range of the three factors was e...

The design of an experiment can greatly affect its potential to produce statistically conclusive results. In this paper, we offer a method for increasing the statistical informativeness of an experiment through the use of adaptive design optimization. The problem to be solved in adaptive design optimization is identifying an experimental design under which one can infer the underlying model and...

Due to the inherent sensitivity of many survey questions, a number of researchers have adopted an indirect questioning technique known as the list experiment (or the item count technique) in order to minimize bias due to dishonest or evasive responses. However, standard practice with the list experiment requires a large sample size, is not readily adaptable to regression or multivariate modelin...

As experimentation in the behavioral and social sciences moves from brick-andmortar laboratories to the web, new opportunities arise in the design of experiments. By taking advantage of the new medium, experimenters can write complex computationally mediated adaptive procedures for gathering data: algorithms. Here, we explore the consequences of adopting an algorithmic approach to experiment de...

one of the most significant issues in pharmaceutical industries, prior to commercializationof a pharmaceutical preparation is the “preformulation” stage. however, far too attention hasbeen paid to verification of the software assisted statistical designs in preformulation studies.the main aim of this study was to report a step by step preformulation approach for a semisolidpreparation based on ...
