This research proposes an experimental design approach to design an ephemeral pavilion located at the Serpentine Gallery in London. The Serpentine Pavilions Programme functions as an experimentation laboratory and, at the same time, public and event spaces, enabling architects to expose their projects and work methodologies. Thus, the methods of Biomimicry and Parametric Design were combined to develop the pavilion. While the first one was used to create an ephemeral pavilion based on the Sartorius muscle, the second was responsible for generating the parametric model from a fast and intuitive manipulation code capable of exploring shape variations. This work explores the solution-based method approached by Badarnah (2012) based on a predefined problem (the pavilion project) and only after that seek some natural inspiration. Firstly, it was investigated the anatomy of the Sartorius muscle. Subsequently, with the domain of the solution, the parametric insertion of the shape was computationally performed. The anatomical study of the sartorius muscle revealed functions such as flexion, abduction, lateral rotation of the thigh, and medial rotation of the knee. Thus, the architectural choices reflect both its narrow and elongated morphology of the muscle and flexibility and rotation aspects. The pavilion also considered the previous Serpentine Pavilions regarding attributes such as area, height, and materials, which with other parameters may be changed using the code implemented in Grasshopper.

Abstract The AOAC colorimetric acetylacetone method for formaldehyde in sugar products is optimized by means of the simplex experimental design process. The resultant method is almost 4 times as sensitive as the original AOAC method. It is about 33% more sensitive than the simplex optimized J-acid procedure and 45% more sensitive than the simplex optimized chromotropic acid method and, thus, represents one of the most sensitive methods now available. The average relative standard deviation is about ±2.7%. The limit of detectability is estimated to be 30 ppb. The didactic exposition of the simplex optimization process reported earlier is applied to the AOAC acetyl-acetone method. Further insights into simplex operations are provided and certain advantages of simplex application are pointed out. It is shown that, by sacrificing the high sensitivity of the optimized method the parameters of the new method result in about a 10-fold increase in analytical speed. Further application of kinetic considerations and the advantages of high quality, productivity, and economy in chemical analytical methods by means of the simplex experimental design process are described.

Failure Mode and Effects Analysis (FMEA) is well-known as a useful tool in the design process. It is used by some engineers as part of process characterization studies. Yet FMEA is virtually ignored in most process quality improvement paradigms. We suggest its use in quality improvement programs and indicate where it belongs and how it can be applied.

In this paper, the design process of BLDC adopting the dual rotor method that can reduce the overall size of the motor while generating the same torque as the conventional Permanent Magnet BLDC is analyzed. A simple size is selected by obtaining the torque per rotor volume (TRV), and a method of matching the counter electromotive force by selecting the pole arc of the magnet through a magnetic equivalent circuit is analyzed. Since the efficiency is low because the 120-degree commutation method is selected, the middle stator is optimized through detailed design through the experimental design method. Afterwards, it has the advantage of being able to shift without stopping due to the characteristic of a dual rotor. For this, an analysis of the driving characteristics for each mode is performed.

Abstract This paper is to present the chosen methodology for research and thus approach the design process through biomimicry. The described methodology is applied in parasitic architecture research, focusing on developing the experimental design of architectural structure using artificial intelligence and thus approach and support the central hypothesis of the work -the effort to create self-designing and self-growing / developing architecture. Furthermore, the paper outlines the ontology as a model of knowledge, a source of data for the developed software © PAF A.I. and a source of inspiration influencing the final design of the proposed architectural structure. The way in which such an ontological resource is processed for research purposes and how it participates in the final design within the verification and validation of the whole conceptual design is also described. Besides, the paper explains why the ontology in question is essential and what was established as its content.
