in some conditions, to avoid deterioration and field losses of soybean seeds (glycine max merr.) from weathering at end of the season, farmers start to harvest seeds with a high moisture content and so, careful post-harvest drying would be required to maintain the physiological quality of seeds. response surface methodology (rsm) was used to optimize the operating conditions of soybean seed dry...

objective(s): response surface methodology (rsm) by central composite design (ccd) was applied to statistically optimize the preparation of rutin-quercetin (ru-qr) dual drug loaded human hair keratin nanoparticles as well as evaluate the characteristics. materials and methods: the effects of three independent parameters, namely, temperature (x1:10-40 c), surfactant (x2: sds (1), sls (2), tween-...

inulin is widely used in functional foods throughout the world for its health-promoting and technological properties. helianthus tuberosus is cultivated widely in the northern part of iran. helianthus tuberosus can be a valuable source of inulin. to optimize conventional extraction of inulin, various combinations of time, temperature, and solvent: solid ratio, were used. in this research, a ser...

gelatin is a protein hydrocolloid. because of its unique characteristics such as gel forming, thickening, stabilizing, emulsifiing, foam and film forming, is widely used in food industries. in this research, in order to optimize the factors which affect enzymatic extraction method of gelatin ,the effects of three variables, enzyme concentrations(2-10 ppm), time(8-16 hours) and temperature(60-80...

Experimental design is a powerful approach to study the impact of potential variables affecting systems and provides spontaneous insight for continuous improvement possibilities. Most research in system design has focused on problems with a single characteristic or response. This paper is concerned with the application of a design method to problems with multiple characteristics. The study sequ...

The design of experiments involving more than one blocking factor and quantitative explanatory variables is discussed, the focus being on two key aspects of blocked response surface designs: optimality and orthogonality. First, conditions for orthogonally blocked experiments are derived. Next, an algorithmic approach to computeD-optimal designs is presented. Finally, the relationships between d...

We investigated if and under which conditions multimodal interfaces (touch, speech, motion control) fulfil the expectation of being superior to unimodal interfaces. The results show that the possibility of multimodal interaction with a handheld mobile device turned out to be more intuitive, more robust, and more preferred than the interaction with the individual modalities speech and motion con...

Several approaches to robust design have been proposed in the past. Only few acknowledged the paradigm shift from performance based design to design for cost. The incorporation of economics in the design process, however, makes a probabilistic approach to design necessary, due to the inherent ambiguity of assumptions and requirements as well as the operating environment of future aircraft. The ...
