Unique Truncated Cluster Expansions for Materials Design via Subspace Projection and Fractional Factorial Design [PDF]

open access: yesarXiv, 2012
For alloy thermodynamics, we obtain unique, physical effective cluster interactions (ECI) from truncated cluster expansions (CE) via subspace-projection from a complete configurational Hilbert space; structures form a (sub)space spanned by a locally complete set of cluster functions.

Application of the fractional factorial design in multiple W/O/W emulsions

open access: yes, 2017
In presented research, multiple W/O/W emulsions were developed by using experimental design method. A 24-1 fractional factorial design was performed by varying the following input parameters: primary polymeric emulsifier (PEG 30-dipolyhydroxystearate ...

Cropping History and Cropland Abandonment Period Influenced Levels of Soil Organic Carbon, Distribution of Aggregates and Aggregate Associated Carbon

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Knowledge gaps remain regarding soil organic carbon (SOC) storage and aggregate dynamics under varying cropland abandonment periods, particularly within the context of degraded and low‐SOC soils. This study aimed to assess the influence of cropping history and the period of cropland abandonment period on SOC, aggregate distribution, and ...

LA PROGRAMMAZIONE DELLA SPERIMENTAZIONE NELLO SVILUPPO DEI PROCESSI CHIMICI

open access: yesRatio Mathematica, 1995
In the present paper the main advantages obtained in the planning of experimental tests by using factorial design are shown. In particular the general criteria to perform a full and fractional factorial experiments are highlighted.

Markov chain Monte Carlo methods for the regular two-level fractional factorial designs and cut ideals [PDF]

open access: yesJournal of Statistical Planning and Inference 143, Issue 10 (2013) 1791--1806, 2013
It is known that a Markov basis of the binary graph model of a graph $G$ corresponds to a set of binomial generators of cut ideals $I_{\widehat{G}}$ of the suspension $\widehat{G}$ of $G$. In this paper, we give another application of cut ideals to statistics. We show that a set of binomial generators of cut ideals is a Markov basis of some regular two-

Nutrient inversion but not warming drive changes in periphyton biomass and composition in shallow lake mesocosms

open access: yesLimnology and Oceanography, EarlyView.
Abstract Periphyton plays an important functional role in shallow lakes and is sensitive to variation in nutrient availability and global warming. Understanding the responses of periphyton to changes in nutrient availability in contrasting warming scenarios can contribute to the development of more efficient techniques for the restoration of lakes in a
