This article will summarise the evaluation of four CFD software codes (CFX, FDS4, SMAFS and SOFIE). Evaluation was performed by means of comparing the simulation data with experimental scenarios. The scenarios were chosen to represent scenarios frequently assessed using fire safety design based on performance. The greatest difficulty during validation of CFD-codes is to find well documented releva

A new Reynolds stress transport model (RSTM) aimed for engineering applications is proposed with consideration of near-wall turbulence. This model employs the SSG pressure strain term, the ω equation, and the SST model for the shear stresses at the near-wall region (say y+ less than or equal 30). The models are selected based on the following merits: The SSG RSTM model performs well in the fully t

In this paper a non-line-of-sight (NLOS) path-loss and fading model developed for vehicle-to-vehicle (V2V) communication at 5:9 GHz is validated with independent and realistic measurement data. The reference NLOS model is claimed to be flexible and of low complexity, and incorporates specific geometric aspects in a closed-form expression.We validated the accuracy of the model with the help of real

Among the formats introduced in Swedish radio in the 1930s, the theatre series about contemporary family life has turned out an exceptional survivor. The first family series, ”Ingenjör Björck med familj” (1936-1943), was followed by 22 related series during the rest of the 20th century, each cultivating its own intimate and ritual based bond with the listeners. The dissertation ”Höra hemma. Familj

This work presents an overview of four different approaches to the problem of future contingency and determinism in temporal logics. All of them are bivalent, viz. they share the assumption that propositions concerning future contingent facts have a determinate truth-value (true or false). We introduce Ockhamism, Peirceanism, Actualism and T x W semantics, the four most relevant bivalent alternati

The paper describes a concept for securing the geometry in flexible production based on robot assisted framing. This uses the robot(s) as an active device during change-over between product variants and it is assumed that product variants can be produced in any mixed order. The case under study is cabs for trucks which in traditional production require large and heavy equipment which is above the

The European research project ‘Experiences of Children from Rainbow Families in School’ (2009 – 2011) conducted by researchers from Humboldt-Universität zu Berlin, Germany (Centre for Transdisciplinary Genderstudies), University Ljubljana, Slovenia (Department of Social Justice and Inclusions, Faculty of Social Work) and Lund University, Sweden (Centre for Gender Studies) focuses in its comparativ
