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
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
My focus is on pragmatic arguments for various rationality constraints on a decision maker’s state of mind: on his beliefs or preferences. An argument of this kind purports to show that a violator of a given constraint can be exposed to a decision problem in which she will act to her guaranteed disadvantage. Dramatically put, she can be exploited by a clever bookie who doesn’t know more than the a
