In this paper, the arbitrary Lagrangian Eulerian formalism is used to compute the steady state of a 2D metal cutting operation and a 3D U-shaped cold roll forming process. Compared to the Lagrangian case, this method allows the use of a refined mesh near the tools, leading to an accurate representation of the chip formation (metal cutting) and the bending of the sheet (roll forming) with a limited computational time. The main problem of this kind of simulation is the rezoning of the nodes on the free surfaces of the sheet. A modified iterative isoparametric smoother is used to manage this geometrically complex and CPU expensive task. c 2007 American Institute of Physics. [less ▲]

A catalog of all the known Ap and Am stars, containing a total of 6684 objects, was prepared. The few stars that were wrongly considered as Ap or Am star are noted as well as some others for which their identity as Ap or Am stars is not yet well established. The catalog gives the identificators and the main observational data for each star, including the magnitude, color, spectral type, duplicity, periodicity, magnetic field, and projected rotational velocity.

A catalogue of 8205 known or suspected Ap, HgMn and Am stars is presented. This is a major update of the catalogue of Ap and Am stars (Renson et al., 1991, III/162). It includes revised identifications, additional stars and revised information. Bertaud and GC identifications were suppressed. HIP and TYC identifications were added. The GC number can be found in notes N for stars without HIP number and for double stars when the components have different numbers (the GC of the other component is then given in note D).

A discontinuous Galerkin formulation of the boundary value problem of finite-deformation elasticity is presented. The primary purpose is to establish a discontinuous Galerkin framework for large deformations of solids in the context of statics and simple material behaviour with a view toward further developments involving behaviour or models where the DG concept can show its superiority compared to the continuous formulation. The method is based on a general Hu-Washizu-de Veubeke functional allowing for displacement and stress discontinuities in the domain interior. It is shown that this approach naturally leads to the formulation of average stress fluxes at interelement boundaries in a finite element implementation. The consistency and linearized stability of the method in the non-linear range as well as its convergence rate are proven. An implementation in three dimensions is developed, showing that the proposed method can be integrated into conventional finite element codes in a straightforward manner. In order to demonstrate the versatility, accuracy and robustness of the method examples of application and convergence studies in three dimensions are provided.

Differential item functioning (DIF) is an important issue of interest in psychometrics and educational measurement. Several methods have been proposed in the last decades to identify items that function differently between two (or more) groups of examinees. Starting from a framework for classifying DIF detection methods and from a comparative overview of the most traditional methods, an R package for nine methods, called difR, is presented. The commands and options are briefly described, and the package is illustrated through the analysis of a data set on verbal aggression. [less ▲]

Conducting round robin exercises is one of EGOLF's key activities. A round robin exercise is a necessary tool to improve and maintain a good level of quality within EGOLF. A good plan of the round robin exercise will make the work easier, and will help avoid problems and misunderstandings. The intention is to give general guidelines on how to organize round robins in a standardized way within EGOLF. The document is divided into the following parts - Preparing and planning the round robin - Testing - Data analysis and reporting These guidelines comply with the ISO 5725 prescriptions. [less ▲]

We consider a stochastic version of the multi-product multi-level capacitated lotsizing and scheduling problem with sequence-dependent setups. A bottler needs to determine its production schedule over a finite horizon in order to satisfy a deterministic demand. The raw materials are supplied through two different sources: uncapacitated reserves of new bottles and the uncertain returns of used bottles. We present results for the single-item case. [less ▲]
