Müller, R.A.J. (author), von Benda-Beckmann, A.M. (author), Halvorsen, M.B. (author), Ainslie, M.A. (author)Regulations for underwater anthropogenic noise are typically formulated in terms of peak sound pressure, root-mean-square sound pressure, and (weighted or unweighted) sound exposure. Sound effect studies on humans and other terrestrial mammals suggest that in addition to these metrics, the impulsiveness of sound (often quantified by its kurtosis...article 2020

Vazquez, A.R. (author), Goos, P. (author), Schoen, E.D. (author)Definitive screening designs permit the study of many quantitative factors in a few runs more than twice the number of factors. In practical applications, researchers often require a design for m quantitative factors, construct a definitive screening design for more than m factors and drop the superfluous columns. This is done when the number of...article 2020

Vo-Thanh, N. (author), Goos, P. (author), Schoen, E.D. (author)Design of experiments is an effective, generic methodology for problem solving as well as for improving or optimizing product design and manufacturing processes. The most commonly used experimental designs are two-level fractional factorial designs. In recent years, nonregular fractional factorial two-level experimental designs have gained much...article 2020

N-of-1 designs gain popularity in nutritional research because of the improving technological possibilities, practical applicability and promise of increased accuracy and sensitivity, especially in the field of personalized nutrition. This move asks for a search of applicable statistical methods. Objective. To demonstrate the...article 2020

Schoen, E.D. (author), Eendebak, P.T. (author), Goos, P. (author)A conference design is a rectangular matrix with orthogonal columns, one zero in each column, at most one zero in each row and -1's and +1's elsewhere. A definitive screening design can be constructed by folding over a conference design and adding a row vector of zeroes. We prove that, for a given even number of rows, there is just one...article 2019

Scherer, L. (author), de Koning, A. (author), Tukker, A. (author)The BRIC (Brazil, Russia, India, China) and MINT countries (Mexico, Indonesia, Nigeria, Turkey) shifted the economic weight from developed to emerging countries. They will continue to grow rapidly by population and gross domestic product (GDP), which could also imply environmental changes. We use the environmentally extended multi-regional input...article 2019

Hansen, S.G. (author), Meinen, N.E. (author), Jørgensen, H.B. (author)Assessment of the load‐carrying capacity of existing concrete structures is often based on the concrete compressive strength obtained from drilled cores. These cores are typically drilled perpendicular to the concrete surface, under the assumption that the mechanical properties of the concrete are isotropic. Recent studies however showed that...conference paper 2019

Hattendorf, H. (author), Hermse, C.G.M. (author), IJzerman, R.M. (author)The focus in this study is on very metal dusting resistant nickel chromium alloys with a high content of chromium (in the range of 22 to 33 wt.%), additions of aluminum (between 0 and 3 wt.%) and variable iron content (between 0.1 and 15 wt.%). All samples were exposed up to 5693 h at 600 °C in a 37 vol.% CO, 7 vol.% CO2, 46 vol.% H2, 9 vol.%...article 2019

(author)Background Undernutrition impairs child development outcomes and growth. In this follow-up study of an open cluster-randomized intervention trial we examined the effects of an education package delivered to mothers in rural Uganda on their children's development, growth and gut microbiota at 36 months of age. Methods The parental trial included...article 2019

Carton, E.P. (author), Johnsen, B.B. (author), Rahbek, D.B. (author), Broos, J.P.F. (author), Snippe, A. (author)The depth of penetration (DOP) method is a well-known ballistic test method for characterisation and ranking of ceramic armour materials. The ceramic tile is bonded to a backing material of semi-infinite thickness, and the penetration depth of the projectile gives a measure of the performance of the ceramic. There is, however, an inherent...article 2019

(author)Typically, ultrasonic flow meters assume linear wave propagation. Nevertheless, if the transducers of an ultrasonic flow sensor excite a pressure wave with a high amplitude, nonlinear wave propagation effects become significant. The appearance of higher harmonics increases the bandwidth of the received signal, which may potentially lead to a...conference paper 2018
