The metafor package provides functions for conducting meta-analyses in R. The package includes functions for fitting the meta-analytic fixedand random-effects models and allows for the inclusion of moderators variables (study-level covariates) in these models. Meta-regression analyses with continuous and categorical moderators can be conducted in this way. Functions for the Mantel-Haenszel and ...

Manufacturing processes such as monitoring and controlling typically confront the user with a variety of heterogeneous data sources and systems. The cognitive efforts to summarize and combine the data from these different sources affect the user’s efficiency. Our goal is to support the user in his work task by integrating the data and presenting them in a more perceivable way. Hence, we introdu...

Open environments are characterized by their uncertainty and non-determinism. This poses an inevitable challenge to the construction of agents operating in such environments. The agents need to adapt their processing to available resources, deadlines, the goal criteria specified by the clients as well as their current problem solving context in order to survive. Our research focuses on construc...

The ultimate goal of metamaterial engineering is to have complete control over the electromagnetic constitutive parameters in three-dimensional space. This engineering can be done by considering either single meta-atoms or full meta-arrays. We follow the first route and perform numerical simulations of split-ring resonators, with different gap numbers and under varying illumination scenarios, t...

The increasing openness and heterogeneity of distributed computing systems requires the representation of meta-information in distributed environments. Most type management systems can only define types within particular type systems. In contrast, the DSTC’s Meta-Object Facility (MOF) first defines a type system as a set of meta-meta-objects, and then defines types as meta-objects which are des...

Two studies examined the compensation hypothesis that members of both highand low-status groups associate high-status groups with high levels of competence and low levels of warmth on the one hand, and low-status groups with low levels of competence and high levels of warmth, on the other. Building upon existing linguistic relations between the French and the Belgians, Study 1 had standard, i.e...

Purpose – The Robots.txt and Robots Meta tags constitute a set of instruments that can be used to instruct software robots. However, the current version of Robots.txt and Robots Meta tags are both too simple and ambiguous in an internet world with many potential conflicts, especially in terms of copyright and trespass to chattels. This paper seeks to propose an amendment to the Robots.txt and R...

The existing resource and topology heterogeneity has divided the scheduling solutions into local schedulers and high-level schedulers (a.k.a. meta-schedulers). Although much work has been proposed to optimise job queue based scheduling, seldom has attention been put on the job sharing behaviours between decentralised distributed resource pools, which in turn raises a notable opportunity to expl...

Our aim in this article is to show how modularity is defined and used in some current modeling languages based on meta-meta-models. These languages are the MOF (Meta Object Facility) [MOF1997] submission which has been submitted to the OMG (Object Management Group) and CDIF [Ernst1997] (Case Data Interchange Format) as defined by the CDIF technical committee and standardized by the Electronic I...

Enterprise Interoperability can be identified on cultural, rule, process, data, software, object, social network, services, knowledge, electronic ID, cloud, and ecosystem level, whereas the challenge is the conceptual integration across those layers in a flexible way. Meta Modeling as a concept is a proven technology to enable such conceptual integration for both machine computation and human-o...
