Incremental elastoplastic analysis for active macro-zones
2012
SUMMARY In this paper a strategy to perform incremental elastoplastic analysis using the symmetric Galerkin boundary element method for multidomain type problems is shown. The discretization of the body is performed through substructures, distinguishing the bem-elements characterizing the so-called active macro-zones, where the plastic consistency condition may be violated, and the macro-elements having elastic behaviour only. Incremental analysis uses the well-known concept of self-equilibrium stress field here shown in a discrete form through the introduction of the influence matrix (self-stress matrix). The nonlinear analysis does not use updating of the elastic response inside each plas…
Convergence of a finite volume scheme for the compressible Navier–Stokes system
2019
We study convergence of a finite volume scheme for the compressible (barotropic) Navier–Stokes system. First we prove the energy stability and consistency of the scheme and show that the numerical solutions generate a dissipative measure-valued solution of the system. Then by the dissipative measure-valued-strong uniqueness principle, we conclude the convergence of the numerical solution to the strong solution as long as the latter exists. Numerical experiments for standard benchmark tests support our theoretical results.
Modeling Changes for SHOIN(D) Ontologies: An Exhaustive Structural Model
2013
Ontology development starts with a rigorous ontological analysis that provides a conceptualization of the domain to model agreed by the community. An ontology, specified in a formal language, approximates the intended models of this conceptualization. It needs then to be revised and refined until an ontological commitment is found. Also ulterior updates, responding to changes in the domain and/or the conceptualization, are expected to occur throughout the ontology life cycle. To handle a consistent application of changes, a couple of ontology evolution methodologies have been proposed. Maintaining the structural consistency is one of the ontology evolution criteria. It implies modeling chan…
Communication: Restoring full size extensivity in internally contracted multireference coupled cluster theory.
2012
The reason for the lack of size extensivity in the valence space in current implementations of internally contracted multireference coupled cluster theories is the procedure used to eliminate redundant components from the cluster operator. We present a simple way to restore full size extensivity by performing this critical step in a basis of excitation operators that are normal ordered with respect to the multiconfigurational reference function.
Towards a methodology to assess organizational learning capability
2011
PurposeThe present study aims to revalidate a measurement scale for organizational learning capability in the context of university faculty members. This is a particularly relevant context because it deals with knowledge‐intensive services. Following Chiva et al., organizational learning capability was conceptualized as a second factor construct including five dimensions: experimentation, risk taking, interaction with the external environment, dialogue and participative decision making.Design/methodology/approachData were collected from the Instituto Tecnológico de Costa Rica, a leading university in Costa Rica. The survey was addressed to faculty members. A total of 795 valid questionnaire…
Psychological Well-Being and Career Indecision in Emerging Adulthood: The Moderating Role of Hardiness
2016
Choosing a career path is an important developmental task during the transition from adolescence to adulthood. However, many emerging adults (EAs)-individuals between 18 and 29 years of age (Inguglia et al., 2016)-struggle to get their career decision-making processes under way because they need a long time to explore various possible career directions (Arnett, 2004; Miller & Rottinghaus, 2014). In particular, this condition concerns EAs who are never employed and is traditionally associated with the construct of career indecision (Gati et al., 2011; Gati, Krausz, & Osipow, 1996), referring to the difficulties that can slow or even stop the career decision-making process.Among such difficul…
The Spanish validation of the Short Health Anxiety Inventory: Psychometric properties and clinical utility
2019
The Short Health Anxiety Inventory (SHAI) is a widely used self-report instrument to evaluate health anxiety. To assess the SHAI's factor structure, psychometric properties, and accuracy in differentiating Spanish non-clinical individuals from patients with severe health anxiety or hypochondriasis.A total of 342 community participants (61.6% women;The original two-factor structure was selected as the best structure, based on its parsimony and empirical support (Factor 1: Illness likelihood; Factor 2: Negative consequences of illness). Moreover, the Spanish version of the SHAI demonstrated good construct and concurrent and discriminant validity, and internal consistency. A cutoff of 40.5 (to…
Comparing equilibration schemes of high-molecular-weight polymer melts with topological indicators.
2021
Abstract Recent theoretical studies have demonstrated that the behaviour of molecular knots is a sensitive indicator of polymer structure. Here, we use knots to verify the ability of two state-of-the-art algorithms—configuration assembly and hierarchical backmapping—to equilibrate high-molecular-weight (MW) polymer melts. Specifically, we consider melts with MWs equivalent to several tens of entanglement lengths and various chain flexibilities, generated with both strategies. We compare their unknotting probability, unknotting length, knot spectra, and knot length distributions. The excellent agreement between the two independent methods with respect to knotting properties provides an addit…
Two Paths to Logical Consequence: Pieri and the Peano School
2021
This chapter1 has two main goals. First, it will explore the “negative” avenue leading from the concepts of independence and consistency to that of logical consequence.
Operative Gesichtspunkte bei der Diskussion des Weberschen Gesetzes
1977
The analysis of structures of argumentation in historical controversies is considered to be a basic contribution to the dynamics of theories. In this paper attention is drawn to the occurence of operational arguments in the history of physics. This is to be discussed especially in respect to the nineteenth-century debates on the consistency of Wilhelm Weber's electrodynamic law with the principle of conservation of energy.
