Teaching Experimental Design [PDF]

open access: yesILAR Journal, 2014
Awareness of poor design and published concerns over study quality stimulated the development of courses on experimental design intended to improve matters. This article describes some of the thinking behind these courses and how the topics can be presented in a variety of formats.

Optimal Experimental Designs

open access: yesThe Annals of Mathematical Statistics, 1966
Abstract : This paper presents a number of results concerning the theory of the optimal design of experiments initiated and principal developed by Elfving, Kiefer and Wolfowitz. The paper contains approximately half expository and half new material. The proofs are mostly new and presented in a unified manner.

Spherical microphone array acoustic rake receivers [PDF]

open access: yes, 2015
Several signal independent acoustic rake receivers are proposed for speech dereverberation using spherical microphone arrays. The proposed rake designs take advantage of multipaths, by separately capturing and combining early reflections with the direct ...

Collagen Extraction Optimization from the Skin of the Small-Spotted Catshark (S. canicula) by Response Surface Methodology

open access: yesMarine Drugs, 2019
The small-spotted catshark is one of the most abundant elasmobranchs in the Northeastern Atlantic Ocean. Although its landings are devoted for human consumption, in general this species has low commercial value with high discard rates, reaching 100% in ...
