The quality of selected AR models depends on the true process in the finite sample practice, on the number of observations, on the estimation algorithm, and on the order selection criterion. Samples are considered to be finite if the maximum candidate model order for selection is greater than 10, where denotes the number of observations. Finite sample formulae give empirical approximations for ...

The main result of this paper is a generalization of Popa’s free independence result for subalgebras of ultraproduct II1 factors [Po95b] to the framework of ultraproduct von Neumann algebras (M, φ) where (M,φ) is a σ-finite von Neumann algebra endowed with a faithful normal state satisfying (M) ∩ M = C1. More precisely, we show that whenever P1, P2 ⊂ M ω are von Neumann subalgebras with separab...

Article history: Received 5 July 2012 Received in revised form 25 September 2012 Accepted 29 September 2012 The fatigue crack growth of the nickel-based superalloy Haynes 230 was investigated at room temperature and 900 °C using digital image correlation (DIC). As expected, the crack growth rates at high temperature were much faster than at room temperature. However, the crack closure levels, w...

Standard maize starch was hydrothermally treated at residual moisture content (~12 %) by Instantaneous Controlled Pressure Drop for various pressure levels and processing times. In order to examine the homogeneity of the starch treatment, three thicknesses (1.5, 1 and 0.5 cm) were tested at 3 bar of steam pressure. For the three thicknesses, the temperature and the moisture content of starch we...

Mergers, acquisitions and divestments, including the carve-outs of business units or parts of them, are standard strategies used by multi-divisional organizations to adjust their business portfolios. Carve-out projects are critically dependent on their management of IT. Systems, which have been integrated in order to deliver seamless and efficient IT operations, must now be pulled apart under d...

The first and second mode stress intensity factors (SIFs) of a contact problem between a half-plane with an edge crack and an asymmetric tilted wedge were obtained using experimental method of Digital Image Correlation (DIC). In this technique, displacement and strain fields can be measured using two digital images of the same sample at different stages of loading. However, several images were ...

The authors point to several problems occurring if DIC = 2D(θ) − D(θ) is applied to missing data models: (i) the focus of the model depends on whether the missing data z are considered as observations or as parameters or integrated out; (ii) the parameter θ may be non-identifiable; (iii) θ can be a poor estimator of θ. They then investigate modifications of DIC mainly based on estimates other t...

1988; Lauritzen & Spiegelhalter 1988) cannot work as there extsts no probability measure that In this paper the elicitation of probabilities from simultaneously meets all constraints. The ratiohuman experts is considered as a measurement process, which may be disturbed by random ·measurement noise'. Using Bayesian concepts a second order probability distribution is derived reflecting the uncert...
