• You have seen the response function contours through the stationary point, and you have seen the 3D response function visualizations. You may recall that I have two competing models, one is derived from the experimental data design for the response…

  • I have been calling my 3D response function a “surface”—which is linguistically feckless at best. Of course, I have some company, the immortal Box, Hunter, and Hunter call the experiment design a response surface method. So note carefully, the response…

  • The Results This bread is very different from the artisanal style with white flour. It is more flavorful, the crust has a similar chewiness and resilience, and the crumb is nice. It is, however, denser than I like. On the…

  • I have executed the experiment design discussed Coffee: Design of the Experiments (Part 2: RSO). This “response surface method” experiment design is carefully crafted to provide the data necessary to fit a formula of the form q = b0T2 +…

  • My oven is gas+electric. The thermostat and ignition are electric, but the heat is from gas. In a power failure my oven would serve well as a cabinet. In the back yard, though, I can cook in a Dutch oven,…

  • Storage of food and affiliated supplies could be a real hassle. It could also be expensive. However, if your plan satisfies some basic requirements it will be both serviceable to your family and economical. Possibly it will enhance your daily…

  • I won’t start the cold extraction experiments until I finish the response surface set, and possibly until I perform some local optimization using the RSO outcome. To warm up, paradoxically, here are some thoughts on cold extraction. The basic process,…

  • A friend of mine intimated today that his food storage plan was principally MRE (meals ready-to-eat), like they use in the military. He noted that the nutritional shelf life was essentially eternal, though I wonder if they would outlast a…

  • Sometimes things happen. Fortunately, there were no injuries. I was using this lump of crud to clamp some wood pieces while the glue cured. Or rather, I was trying to do so. The tension I had on the clamp was…

  • In Review The results of my 4-trial fractional factorial experiment (main effects) showed that extraction time is the most important variable, and that temperature and C/W ratio are less important. In the interest of completeness this experiment will not simply…
