This paper suggests that the Payne models should not properly be regarded as the traffic flow analog of the Navier-Stokes equations of fluid dynamics. Further, the Chapman-Enskog asymptotic expansion in a small parameter is shown to lead to an alternate class of models that seem to have a more legitimate claim to that distinction. Details of this expansion, about the stable-flow equilibria of the

Popular Abstract in Swedish Neuoroblastom är en av de tumörformer som oftast drabbar små barn. Eftersom tumörer lyckligtvis är relativt ovanliga hos barn drabbas inte fler än i genomsnitt 14 barn årligen av neuroblastom i Sverige. Tyvärr finns dock, trots den effektiva behandling som kunnat arbetas fram för många andra barncancerformer, idag ingen verksam behandling att tillgå för så många som hälNeuroblastoma is a tumor of sympathetic nervous system derivation, mostly afflicting young children. This thesis is focused on a group of receptor proteins for neurotrophic factors, the Trk family, and on N-Myc, a transcription factor, all important in the formation of the sympathetic nervous system as well as in determining neuroblastoma patient outcome. Expression of trkA and trkC is linked to f

Solar steam turbines are subject to high thermal stresses as a result of temperature gradients during transient operation, which occurs more frequently due to the variability of the solar resource. In order to increase the flexibility of the turbines while preserving lifing requirements, several operational modifications for maintaining turbine temperatures during offline periods are proposed and

Reality TV is popular entertainment. And yet a common way to start a conversation about it is ‘I wouldn’t want anyone to know this but…’ Why do people love and love to hate reality TV? This book explores reality TV in all its forms - from competitive talent shows to reality soaps - examining a range of programmes from the mundane to those that revel in a spectacle of excess. Annette Hill’s resear

The paper will discuss the design of a new organization of library services at Lund University, Sweden with special emphasis on the motives and drivers behind the reorganization. The university management has decided the reorganization after an evaluation report with recommendations. The new structure of the library services is designed as a network of libraries with a coordination and management

The amount of data in large-scale software engineering contexts continues to grow and challenges efficiency of software engineering efforts. At the same time, information related to requirements plays a vital role in the success of software products and projects. To face the current challenges in software engineering information management, software companies need to reconsider the current models

In the electricity market of today, with increasing demand for electricity production on short notice, the combined cycle power plant stands high regarding fast start-ups and efficiency. In this paper it has been shown how the dynamic start-up procedure of a combined cycle power plant can be optimized using JModelica. org, proposing a way to minimize the start-up time while maximizing the power pr
