Stochastic modeling and simulation of multi-lane traffic

A multi-lane traffic flow model based on stochastic noise driven dynamics is introduced and analyzed. The model employs conservative anisotropic Arrhenius spin-exchange (surfacediffusion) dynamics. We generate an asymmetric simple exclusion process to model vehicleinteractions. Vehicles react and advance based on the energy profile of their surrounding trafficthrough a novel look-ahead asymmetric

Renblåsning och rotorkanalform

Regenerativ värmeväxling med rotor har ett varvtalsberoende överföringsflöde med frånluft till tilluft, vilket elimineras med ett renblåsningsflöde. Det är inte självklart att en rotor blir renblåst även om renblåsningsvolymen för en rotorkanal är större än rotorkanalens volym. Syftet med denna arbetsrapport är att komplettera en tidigare arbetsrapport med titeln Ren- blåsning med diffusion TV

On Volume Average Relations in Continuum Mechanics, Part II

This paper continues the analysis of volume average relations that was initiated in [1]. In this paper, as well as in the previous one, results from various investigations, presented in the literature, have been reviewed and extended and they have, in some cases, been more precisely stated and rigorously proven. Some of the results in the present paper are believed to be entirely new. The key obje

Supply Chain Security Programs - Comparing business and authority certifications

A new topic that during the last years has come to the attention of researchers is supply chain security. Stakeholders are progressively realizing the importance to join the authority regulations issued by governments (e.g. AEO) to reduce transport delays at Customs or other business certifications (e.g. TAPA) to reduce theft or counterfeiting. However the differences and impacts of security certi

Exception Handling in Recipe-Based Batch Control

Exception handling constitutes a large part of the design and implementation effort in batch production, but so far little work has been carried out to specify this area. This paper proposes an internal model approach for unit supervision using Grafchart. It also discusses exception handling at the recipe level.
