Publisher: name: Swinburne
Year: 2024

description: Damping constants of free oscillations of coupled gas bubbles change considerably when time delays due to the finite speed of sound in the surrounding liquid are taken into account. This effect is illustrated analytically by the example of a two-bubble system and numerically by the example of a bubble chain. By comparing the numerical data with experimental measurements, it is shown that allowing for time delays considerably improves agreement between theory and experiment.
Modelling wear and crack initiation in rails
Creators: name: Franklin, F. J.

Publisher: name: Swinburne
Year: 2024

description: Wear and crack initiation of steel rails is a problem of great significance to the railway industry. A high wear rate shortens the life of rails and the frequent rail replacement is expensive in terms not only of resources but also of track access time and delays affecting timetables. In addition, railhead profiles change gradually as the rails are worn and the greater the wear rate, the more often the rails need to be reground to maintain good train running performance. In contrast, a low wear rate means that cracks have time to develop in the plastically deformed rail steel and these may propagate deeper into the rails with potentially disastrous consequences. Finding the optimum combination of wear and grinding to maintain railhead profile and prevent cracks from growing is key to running a safe and cost-efficient railway. The large number of variables arising from track geometry, train dynamics, and wheel and rail profiles leads to wide variation in contact patch size and location. The two-dimensional model of ratcheting wear developed by Kapoor et al. has been developed to model the damage accumulation near the surface of the rail on the basis of a full three-dimensional contact stress distribution. Different rail steel microstructures can also be modelled and the effects of microstructure on wear and crack initiation are explored.

Fodgængeres trafiksikkerhed

Year: 1997

description: I perioden 1986-95 faldt antallet af dræbte og tilskadekomne fodgængere med 26% i Danmark. Men siden 1981 og op til 1993-95 steg risikoen for at gå én kilometer i vejtrafikken med ca. 23%. Dette skyldes, at danskerne går færre og færre kilometer. Alligevel er gang en forholdsvis sikker transportform. Faktisk er en gangtur mere sikker end en cykeltur eller en tur i personbil - ifølge den officielle statistik. Ældre fodgængere har en væsentlig højere risiko for at blive dræbt eller kvæstet i trafikken end yngre til fods. Det er også langt farligere at bevæge sig til fods i mørke end i dagslys, især i landområder. Da 20% af de dræbte fodgængere er spirituspåvirket, må fulde fodgængere ligeledes være en højrisikogruppe. Væsentlige indsatsområder overfor dødsuheld med fodgængere er derfor ældre fodgængere, mørkeuheld og fulde fodgængere. Omkring 75% af fodgængeruheldene sker, når fodgængeren krydser vejen. Den største udfordring er at reducere risikoen ved krydsning af vejen. I paperet præsenteres en liste over sikkerhedseffekter for fodgængere af en række foranstaltninger. Listen er baseret på litteraturstudier og analyser af danske fodgængeruheld, og indeholder blandt andet effekter af fodgængerfelter, midterheller og rundkørsler.

description: We assessed the molecular genetic diversity and population structure of Amaranthus species accessions using 11 simple sequence repeat markers. A total of 122 alleles were detected, and the number of alleles per marker (NA) ranged from 6 to 21 with an average of 11.1 alleles. The frequency of major alleles per locus ranged from 0.148 to 0.695, with an average value of 0.496 per marker. The overall polymorphic information content values were 0.436–0.898, with an average value of 0.657. The observed heterozygosity (HO) and expected heterozygosity (HE) ranged from 0.056 to 0.876 and from 0.480 to 0.907, with average values of 0.287 and 0.698, respectively. The average HO (0.240) was lower than the HE and gene flow (Nm), and showed substantial genetic variability among all populations of amaranth accessions. The sample groupings did not strictly follow the geographic affiliations of the accessions. A similar pattern was obtained using model-based structure analysis without grouping by species type. Knowledge of the genetic diversity and population structure of amaranth can be used to select representative genotypes and manage Amaranthus germplasm breeding programs.
Investigating fluid penetration of rolling contact fatigue cracks in rails using a newly developed full-scale test facility

description: Fluid penetration of surface breaking rolling contact fatigue cracks in rails is believed to be a key factor in their growth to dangerous lengths. Fluid entry has been proved for surface breaking cracks in laboratory twin disc contact simulations, but the authors are not aware of direct evidence for fluid penetration of cracks in full-scale rail-wheel contacts. There is, however, a widely held view that the behaviour observed in the laboratory will translate to full-scale cases. To investigate fluid penetration of cracks in full-scale rail-wheel contacts, cracked rails with a range of rolling contact fatigue severity were removed from mainline railway track and re-installed at a newly developed test facility. Investigation was undertaken using two different water-based marker fluids, and the rails subjected to over 1000 wheel passes with a locomotive. The rails were subsequently removed and selected crack faces broken open for observation by placing the rail in four-point bending. Ultra-violet and visible light were used to assess the degree to which the marker fluids had entered the surface breaking cracks. Good evidence of fluid penetration was found for one of the marker fluids, but the second fluid was not observed inside the cracks. The possible reasons behind this difference in behaviour are discussed.

description: A model of plastic strain accumulation, wear, and rolling contact fatigue (RCF) crack initiation in rail steel has been developed. Local to the contact zone, material is subject to severe cyclic stresses taking it beyond yield and leading to incremental accumulation of plastic deformation (ratcheting). This model is based on a ratcheting law derived from twin-disc, rolling-sliding contact experiments and can simulate thousands of ratcheting cycles with corresponding strain hardening. The model is being further refined to account for detailed microstructural changes. Sections of worn and fatigued rail, removed from service, have been metallurgically analysed. To obtain further data on rail-steel deformation and RCF crack initiation, twin-disc tests have been performed using discs cut from across a railhead and wheel rim. Two heat treatments were applied to some rail discs to investigate the effect of pro-eutectoid ferrite phase distributions and volume fractions. Tests were run to failure (defined by an eddy current crack-detection system) and to percentages of fatigue lives. Micro- and nano-hardness tests, and microstructural observations, have been used to suggest a micromechanism of fatigue crack initiation for the model. Application of this model will contribute to reduced maintenance costs and an improved understanding of RCF development.
Rapid method of stress intensity factor calculation for semi-elliptical surface breaking cracks under three-dimensional contact loading
Creators: name: Fletcher, D. I.
name: Kapoor, Ajay
Publisher: name: Swinburne
Year: 2024

description: Fast methods of stress intensity factor calculation for inclined surface breaking cracks under contact loading are presented. Cracks are loaded in normal and tangential traction by a three-dimensional Hertzian elliptical contact patch, and friction between the crack faces is considered. Stress intensities are calculated from Green's functions originally developed for two-dimensional cracks through application of stresses on a plane below the three-dimensional contact patch, in place of those previously considered for a two-dimensional contact. This approach gives the method great speed advantages over fully three-dimensional methods. Both semi-circular and semi-elliptical cracks are examined. The validity of the approximations and the results are judged by validation with results from alternative fully three-dimensional cases. Very good agreement is found between trends in stress intensity factor with changes in crack size and applied tractions. Absolute values of stress intensity factor agree well for semicircular and shallow semi-elliptical cracks, but values were below those of the reference case for deep, narrow semi-elliptical cracks. Calibration of the model to overcome this under-prediction is discussed. A case of special value in railway rail-wheel contact modelling is that of a contact offset to the side of a crack, representing the wheel running alongside rather than directly across an existing crack. This configuration results from the common procedure of grinding the rail to change or maintain its cross-sectional profile. The three-dimensional contact patch methods presented here enable this case to be modelled while retaining very fast running times for the calculations.

Growth of multiple rolling contact fatigue cracks driven by rail bending modelled using a boundary element technique

Publisher: name: Swinburne
Year: 2024

description: Examination of rails on which large rolling contact fatigue cracks have developed, either at the gauge corner or on the rail head, typically reveals that the cracks have not developed in isolation but occur at intervals along a length of track. Individual cracks are typically separated from one another by a few millimetres, although the reasons for this spacing between the cracks are not yet understood. This paper presents an investigation into the interaction between adjacent long cracks (tens of millimetres) that are at the beginning of their bending-stress-driven propagation phase. Results are presented as plots of stress intensity factor around crack fronts for single- and multiple-crack situations, for which crack growth rates are predicted. The work focuses particularly on the degree to which single-crack models may be misleading when dealing with a rail containing multiple cracks. The work has application in improving the modelling of crack growth in rails, leading to improved asset management and risk assessment.

Arbejdet blev lagt an på eksisterende modeller: Ørestadstrafikmodellen suppleret med IFP's rutevalgsmodeller (11 & 12). Men derudover blev der benyttet en 'minimum-maksimum' modelstrategi til at afdække, hvilke trafikkomponenter, det var relevant at undersøge nærmere, f.eks. nygenereret trafik. Ligeledes blev der givet anbefalinger om arealanvendelse (herunder udbygning af Holmen og Refshaleøen), lastbiltrafik, detaljerede rutevalg, trafiksanering af Kbh.'s centrum, turfordeling og transportmiddelvalg. Mange alternativer blev undersøgt, hvoraf nogle klart kunne afvises. Arbejdet blev afsluttet med en række anbefalinger til en eventuel efterfølgende mere detaljeret udredning om projektet. Nogle af disse anbefalinger var overraskende selv for erfarne trafikplanlæggere (inkl. undertegnede). Modelarbejdet må derfor i høj grad siges at have haft sin berettigelse.

Computer simulation of strain accumulation and hardening for pearlitic rail steel undergoing repeated contact

Publisher: name: Swinburne

description: This paper presents a validated model of plastic strain accumulation in railway rail steel under repeated wheel-rail contact. Such contacts subject the rails to severe stresses, taking the material local to the contact beyond yield, and leading to the incremental accumulation of plastic deformation (ratheting) as wheels pass. This process is at the root of several rail wear and rolling contact fatigue crack growth mechanisms. Existing plasticity models are inadequate for modelling the strain accumulation taking place in this material, which is under high hydrostatic compression (of the order of 1 GPa) and is severely anisotropic. The model described here is based on a ratcheting law derived from small-scale twin-disc rolling-sliding contact experiments and simulates tens of thousands of ratcheting cycles and the corresponding strain hardening in a few minutes on a personal computer. Results indicate that, to model these processes successfully, and to represent correctly the high levels of ductility seen in rail steels under compressive load, stress-strain data generated under high hydrostatic compression are required.

En arbejdsgruppe med kommunen, beboerrepræsentanter, politi og Vejdirektoratet udarbejdede projektet, som består af zone 40 km/t skilte på de fire indfartsveje, plateauer i kryds og bump på de lange, lige veje. Der blev gennemført en kampagne efter indvielsen af de ny hastighedsgrænser 1. oktober 1996, med husstandsomdelte foldere om skolekonkurrence. Evalueringen viser, at hastighederne er faldet. Målinger udført et halvt år efter indvielsen viser et fald i gennemsnitshastigheder på ca. 20 % på vejene i området. Der blev lavet en spørgeskemaundersøgelse i området som viser at tre ud af fire i området synes at 40 km/t eller lavere er en passende hastighed i området. Der er udarbejdet en hastighedsplan for Gladsaxe kommune, som foreslår zoner med hastighedsbegrænsning på 40 km/t i alle lokalområder.

description: Økonometriske modeller for transportadfærd som transportmiddelvalg, bilejerskab, rejseformål, etc. er sædvanligvis baseret på stokastisk nytteteori. Ved at lave forskellige antagelser om den underliggende stokastiske proces fås modeller som spænder fra simple logit modeller til mere generelle probit modeller. Eftersom responsvariablen er diskret er det ikke muligt at teste antagelser vedrørende den underliggende stokastiske proces. Konsekvensen er, at kun relativt lidt information om modellens validitet kan etableres. I dette paper tages der hul på beskrivelsen af den klasse af misspecifikationer, som skyldes skjulte ikke-lineariteter. Det vises, hvorledes misspecifikationer i modal-split modeller er tæt koblet til rejseafstand og i sidste ende til ændringer i den marginale rejsemodstand. Helt præcist vises det at to respondenter med forskellig marginal rejsemodstand ikke kan antages at have identiske fejlled. Yderligere vises det, hvorledes disse misspecifikationer er systematiske og en oplagt løsningsmåde foreslås.

A Model for Freight Transport crossing Storebælt
Creators: name: Sørensen, Anders
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 1997

description: In this note a model for growth in total freight transport crossing Storebælt is put forward. First, a model forecasts redistribution of freight generated by reduced transportation costs caused by the Fixed Link. Redistributed freight originates from present internal traffic within Jylland/Fyn or Sjælland/Lolland-Falster that will cross Storebælt in the future after establishment of the Fixed Link. This is the gravity model. Second, the results from the gravity model is compared with the existing literature. In Section 2, the gravity model is analysed. Here, the applied data set is discussed and the model is formulated and estimated. Moreover, the model is applied to forecast redistributed traffic in rela- tion to establishment of the Fixed Link crossing Storebælt. In Section 3, the estimated elasticities of freight volumes with respect to the production value are discussed and compared to estimates available from existing literature. Section 4 concludes.

description: Статья посвящена критике Мартином Хайдеггером современной естественной науки. Основная его претензия к естествознанию состоит в том, что оно не способно включить в себя исследования человека. Анализируются критические аргументы немецкого мыслителя. Статья состоит из четырех частей. В первой части содержится хайдеггеровская репрезентация современного естествознания. Обосновывается, что истоки современной естественной науки уходят своими корнями в западно-европейскую науку Нового времени. Показано, что в отличие от созерцательного познания древних греков западноевропейская наука Нового времени представляет собой рас-смотрение, «разделывание» результатов когнитивной деятельности. Во второй части репрезентации анализируется другой недостаток современной естественной науки — ее участие в поставе (Geshtell). Постав — термин, изобретенный и введенный в философию Хайдеггером. Постав несет ответственность за техническую гонку, свидетелями которой мы являемся. В третьей части содержится критика критики науки, представленной как приверженцами современного естествознания, так и его критиками. В четвертой части анализируется проект новой науки Хайдеггера, призванной заменить современное естествознание в качестве основы науки о человеке. Показано, что Хайдеггер не собирается отказываться от естествознания, но полагает, что оно, для того, чтобы включить в себя исследования человека, должно быть модифицировано. Выдвигается предположение, что с позиции немецкого мыслителя нужен синтез модифицированного естествознания с экзистенциальными факторами. Анализируются трудности, встающие на пути создания синтеза и поисков его механизма.

description: Tribological behaviour (friction and wear) of heavily loaded lubricated surfaces is found to be influenced by the presence of very small scale surface textures. The Indirect Structuring process, which is described here, is a new method of surface texture production through implantation of a surface with wear-resistant regions. During use a surface texture is developed and maintained because, at a given wear rate, the wear-resistant regions can sustain higher contact pressures than can the substrate. Indirect Structuring of a tool steel surface was carried out by laser implantation of the surface with titanium carbide implants, and rolling contact experiments were conducted under elastohydrodynamic and mixed-lubrication regimes. It was found that the indirect structuring process produces a surface structure which fulfils the design requirements for textured tool surfaces, and which is insensitive to the load applied to the surface. The mechanisms found to steer the development of the surface texture may be used to develop design methods for application of the Indirect Structuring process.

The aim of this thesis was to design and deliver a multifaceted, clinically integrated EBM curriculum and to evaluate its feasibility and impact in two UK medical schools.MethodsTo address research questions related to the overall aim of the thesis, the following work packages were undertaken:a) A systematic review was carried out to identify validated tools to evaluate EBM teaching.b) After redesigning EBM teaching, the Fresno test was used as a progress test in years one and two to evaluate the effectiveness of EBM teaching.c) Two approaches to delivering EBM teaching (face-to-face vs online) were tested during years three and four of the MB ChB programme. Students’ performance in Assessing Competency in EBM (ACE), Educational Prescriptions (EP), written summative examination and EBM Objective Structured Clinical Examination (OSCE) were compared for the two approaches.d) Six EBM OSCE stations were developed with increasingly complex tasks, with an aim to establish a spiral approach for EBM assessments.e) Medical students’ perceptions of EBM training were explored using focus groups.Resultsa) Six tools of reasonable validity for evaluating EBM teaching were identified. One of these, the Fresno test was selected for further use within this thesis.b) Evaluation of EBM teaching demonstrated a significant increase in knowledge, the average score increased by 38.7 marks (p<0.001).c) Students performed similarly in ACE, written assessment and the OSCEs in both approaches to teaching, while students in the face-to-face teaching approach performed better in EPs (MD=‐2.28, 95%CI: ‐4.31, ‐0.26).d) Five of the six EBM OSCE stations had excellent correlation coefficients and a high reliability ranging from 0.21‐0.49.a) EBM was perceived to be important by medical students during training and for future practice.ConclusionsIt was feasible to develop and implement a multifaceted, clinically integrated EBM teaching in two medical schools in UK. Evaluation of the curriculum has demonstrated a significant increase in students’ EBM knowledge. A spiral approach to assessments can provide evidence for assessing scaffolded learning and mastery of EBM competencies.

description: Here we provide information on an individual of Amphisbaena alba (Reptilia: Squamata) recognizing and using a foraging trail of leaf-cutting ant Atta laevigata (Hymenoptera: Formicidae) in the Brazilian Neotropical Savanna. We also recorded and described movements to deviate from obstacles and the behavior of A. alba to recognize the ants trail. Additionally, we discuss how the chemical mimicry of A. alba could be involved in our observation and we suggest that this relationship goes beyond a simple inquilinism, where A. alba can use the nest as a site for nesting and feeding of other organisms associated with leaf-cutting ants nests.
Estimation af turmatricer ud fra snittællinger – to metoder

description: I praktiske modelarbejder er det ofte meget ressourcekrævende at etablere viden om trafikanternes turmønstre i form af turmatricer. Derfor kan der opnås store besparelser ved brug af metoder, der estimerer matricerne ud fra snittællinger. Men de fleste af disse metoder bygger på meget simplificerede forudsætninger, f.eks. simplificerede rutevalgsmodeller eller at tællingerne er fejlfri deterministiske variable. Uden disse forudsætninger er metoderne så beregningstunge, at de er uanvendelige i praktiske modelarbejder. Artiklen beskriver to metoder til estimation af turmatricer, der ikke har disse problemer. I begge metoder udjævnes inkonsistente tællinger af andre tællinger, hvorved resultatet ikke påvirkes så alvorligt som i de fleste andre matrixestimationsmetoder. Derudover tager rutevalgsmodellerne både hensyn til kapacitetsproblemer, tilfældige forskelle i rutevalg samt forskelle i trafikanters præferencer. Dette giver en mere virkelighedsnær beskrivelse af trafikken, end med mere simplificerede modeller. Den første metode, Single Path Matrix Estimation – SPME, er forholdsvis let at implementere og kan i et vist omfang bygge videre på eksisterende modelpakker. SPME udnytter imidlertid kun tællingerne langs de ’optimale’ ruter. Den nye metode, Multiple Path Matrix Estimation – MPME, er derimod vanskeligere at implementere, men udnytter alle ruter mellem hvert zone-par til estimationen, og afspejler derved rutevalgsmodellerne bedre end SPME. MPME er benyttet i flere fuldskala trafikmodeller med gode resultater. Hvis en turmatrix estimeres på basis af MPME, vil den i mange tilfælde kunne erstatte dyre rejsevaneundersøgelser. Dog er metoden afhængig af udgangsmatricen, hvorfor denne bør have en vis gyldighed. Ligeledes blive turmønstret ikke helt så uddybende beskrevet som ud fra rejsevaneundersøgelser. Det er således primært ved mere skitse-prægede modelarbejder, at metoden er relevant.

Beyond Entropy and Bits: NSI v2.0 Formalism for Coherence-Gated Structural Information

description: Classic information measures like Shannon entropy and Kolmogorov complexity face inherent limitations when applied to complex, structured data prevalent in physical, biological, and cognitive systems. They often fail to distinguish meaningful organization from random noise or adequately capture the role of internal coherence. This paper introduces NSI v2.0 (Nonlinear Structural Information), a fundamentally revised theoretical framework and operational metric designed to overcome these limitations.

NSI v2.0 is built upon a rigorous axiomatic foundation using functional analysis. It uniquely defines informational complexity through the interplay of three core components: Structural Intensity (Iform), quantifying gradient energy or form; Coherence (κ), measuring phase or directional alignment; and Residual Entropy (H), capturing remaining unpredictability. These are integrated into a novel composite metric, INSI, reformulated as a normalized ratio κ*I_rel / (κ*I_rel + (1-κ)*H_rel + ε). This revised formulation posits that information manifests primarily through structure made coherent, rendering information negligible as coherence vanishes (κ → 0).

This new version explicitly addresses critical issues of previous approaches, including:

Contextual Normalization: Replacing unstable global min/max scaling with robust intra-contextual relative metrics (I_rel, H_rel) for improved stability and generalizability.

A Priori Decorrelation: Introducing analytical methods (e.g., geometric mean decomposition Z = sqrt(I*H)) to separate collinearity between Iform and H without statistical training, ensuring component independence.

Computable Complexity Proxy: Defining a pseudo-complexity measure K* based on the coding length of NSI features (-log2 p(I, κ, H)) as a practical bridge to algorithmic complexity.

Tensor Generalization: Extending the framework naturally to multichannel and multimodal data.

We present the complete axiomatic system (NSI v2.0), operational formulas for metrics, the context-aware normalization scheme, the decorrelation technique, the K* construction, and the tensor extension. Preliminary validation on synthetic and semi-realistic data confirms the theoretical predictions, including limit behaviors and high discriminative power (AUC ≈ 1.0) for classifying order vs. chaos and detecting anomalies. NSI v2.0 offers a robust, interpretable, and computationally tractable foundation for analyzing and modeling information in structure-rich, dynamic systems across diverse scientific and technological domains.
Toward a Unified Theory of Complexity and Information: Phase, Form, and Coherence Beyond Shannon

description: We propose a New Theory of Complexity and Information (NSI) that unifies Shannon entropy, Kolmogorov complexity, and nonlinear phase-structured models of meaning and form. Classical information theories quantify uncertainty or compressibility but fail to account for morphology, coherence, and semantic resonance. NSI introduces a hybrid metric combining entropy with morphological structure, governed by a coherence parameter κ\kappaκ. We formulate a 17-axiom foundation, prove key inclusion theorems (Shannon, Kolmogorov), define a category-theoretic structure, and demonstrate the theory through simulations on images, text, and signals. NSI offers a fundamentally new framework for perception, computation, cognition, and information health. We invite further exploration of its physical, cognitive, and technological implications.

description: Under the auspices of the World Climate Research Program WCRP, the climate modelling community organises international coordinated numerical experiments, named the Coupled Modelling Intercomparison Project (CMIP). These experiments form an important basis for the Intergovernmental Panel on Climate Change (IPCC) Assessments Reports, which analyse model evaluation and projections of possible future climate change. The IPCC Assessment Reports provide one of the strongest influences on international policy from the scientific community. Indeed in 2007, the Nobel Peace prize was awarded jointly to IPCC and Al Gore Jr. "for their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change". The community is now actively involved in the 6th phase of CMIP (CMIP6). We present here an analysis of the High Performance Computing (HPC) and associated data resources used for CMIP5 conducted in 2008- 2013 by European climate modelling centres, and a first extrapolation for CMIP6.
EDB-simuleringsmodeller til brug ved jernbaneplanlægning

description: Fremtidens jernbanedrift vil stille nye og store krav til jernbaneplanlæggerne. Med banernes liberalisering vil det betyde, at banerne skal kunne udnyttes mere fleksibelt. Dette vil ligeledes afstedkomme, at der ofte vil være tale om komplekse planlægningsopgaver, som kun vanskeligt lader sig løse med almindelig "købmandsregning". Det er derfor nødvendigt at inddrage EDB-modeller, som kan afprøve de forventede trafiksituationer. Afhængigt af planlægningsniveauet (strategisk, taktisk og operationel) og opgavetypen (f.eks. sporvedligeholdelse, materieldisponering eller kapacitetsundersøgelser) kan forskellige EDB-modeller være særdeles relevante som hjælpeværktøj. Nogle har disse modeller er beskrevet i dette paper.

Behandling af kollektiv trafik i trafikmodeller
Creators: name: Brems, Camilla Riff
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 1997

description: Behandlingen af kollektiv trafik i trafikmodeller bør på grund af den kollektive trafiks særlige egenskaber ske i modeller, der tager hensyn til disse egenskaber. Mange af de særlig egenskaber knytter sig til rutevalget, hvorfor en række anvendte rutevalgsmodeller sammenlignes ligesom de vurderes med hensyn til deres behandling af de særlige egenskaber. Afprøvning af de præsenterede modeller på et fælles eksempel viser markante forskelle i fordelingen af trafik på linier. Strukturen af rejser med (hovedsageligt) kollektiv trafik lægger op til at modellere valg af transportmiddel og rute samlet ved hjælp af turkæder. Introduktionen af turkæder indebærer en mere detaljeret modellering af både transportmiddelvalg og rutevalg sammenlignet med den nuværende situation. Der præsenteres en række forskellige modelopbygninger til behandling af turkæderne. Disse afspejler forskellige opfattelser af delene i en turkæde og stiller samtidig forskellige krav til modelleringen af henholdsvis transportmiddelvalg og rutevalg. Estimation af modellerne forudsætter dog et datagrundlag som så vidt vides ikke er til stede i Danmark i dag.

description: Le Macbeth de Verdi est un cas emblématique de l’héritage shakespearien : la rencontre entre un artiste romantique à la carrière ascendante et un auteur dramatique du passé désormais érigé en icône universelle. Si cet opéra s’inscrit dans une démarche respectueuse de sa source d’inspiration, il est d’abord le résultat de la découverte d’une figure de la littérature anglaise par un jeune italien, quasiment dilettante en la matière.
