description: Formålet med denne undersøgelse var at opnå større viden om hvilke trafikale situationer, som udløser vrede hos forskellige trafikantgrupper. Datagrundlaget for undersøgelsen var en repræsentativ spørgeskemaundersøgelse blandt 2000 personer i Danmark. Analyserne viste, at trafikanter særligt ofte bliver vrede over to typer af adfærd hos andre trafikanter: uopmærksomhed/manglende orientering og hensynsløshed. Analyserne viste desuden en række forskelle mellem undergrupper i befolkningen, fx bliver kvinder oftere end mænd vrede over farlig adfærd, og mænd bliver vrede over bilister, som holder i vejen. Generelt bliver individer oftest vrede over adfærd, som går ud over dem selv – fx bliver bilister vrede over andre bilister, som trækker for tæt ind foran, og cyklister bliver vrede over fodgængere på cykelstierne.

Rapid approximate 3D inversion of transient electromagnetic data
Creators: name: Schaa, R
Publisher: name: University Of Tasmania
Year: 2023

description: Three-dimensional geophysical inversion of EM data aims to give an idealised estimate of the 3D geoelectrical structure of the subsurface which can meaningfully describe a set of observations. Rigorous 3D inversion of time-domain electromagnetic data is an onerous computational challenge, often taking several hours or even days. Motivated by the demand for a rapid and reliable 3D inversion method for TEM data, a fast, approximate 3D inversion of transient electromagnetic data has been developed. The new scheme combines the TEM moments concept and geologically constrained 3D inversion methodology. The TEM moment inversion scheme builds on the pre-existing VPmg potential field modelling and inversion framework which has been extended and modified so as to accommodate approximate 3D TEM inversion. The method has potential for fast, constrained 3D inversion of large airborne TEM data sets. The moment transform of TEM data is a time-weighted integral of the impulse response which accentuates late-time features. Due to the time integration, a TEM decay is effectively reduced to a single value. Depth resolution is lost due to the time integration, which, in effect, converts the nonlinear 3D TEM inversion problem into a linear 3D magnetic inversion problem. Using TEM moments, EM interaction may tolerably be ignored, therefore justifying linear superposition of TEM responses. 3D TEM forward modelling is realised as a linear combmation of a discretised 3D target response and a continuous background response. Superposition of the TEM moment responses of magnetic dipoles, distributed on a cubic mesh, gives the target response whereas the TEM moment response of a half space serves as the background response. Computations are based on analytical formulae. For the approximate scheme, a reduction in accuracy is accepted as a trade-off for much improved speed of calculation. For the 3D inversion, a starting model (or a set of weights) generated from conductivity-depth imaging ( cor) is used to inject depth resolution. The CDis are based on total magnetic field data which facilitates derivation of unambiguous apparent conductivities for fixed-loop TEM. Depth resolution is also recovered by means of geological constraints and depth weighting. The underlying model is both geological and petrophysical, so that the inversion can be focused on selected units. A fast steepest descent method is employed, so that computationally slow matrix inversion is not required Typically, for ground-TEM, the fast approximate 3D inversion completes in minutes, thus facilitating exploration of non-uniqueness. The inversion scheme was successfully tested on synthetic fixed-loop TEM examples and on fixed-loop TEM field data from South Africa.

description: We prove a general bound on the superpotential in theories with broken supersymmetry and broken R-symmetry, 2|W|< f_a F, where f_a and F are the R-axion and Goldstino decay constants, respectively. The bound holds for weakly coupled as well as strongly coupled theories, thereby providing an exact result in theories with broken supersymmetry. We briefly discuss several possible applications.

The reproductive ecology of vascular plants on subantarctic Macquarie Island
Creators: name: Shaw, JD
Publisher: name: University Of Tasmania
Year: 2023

description: Southern Ocean islands have long been sites of scientific interest, due to their isolation, climate, geology and biology. This study investigated reproductive ecology of vascular plants on subantarctic Macquarie I. The persistence of plant species in a community relies on life history strategies which ensure population growth and sustainability. This can be via either vegetative or sexual reproduction. Many studies have shown that for alpine and high latitude plants sexual reproduction is not an important life history trait. The study identified that 26 species flowered, 22 dispersed seed and 12 produced seedlings over the study period on Macquarie I. This represents 72%, 61 % and 33% of the angiosperm flora of the island, respectively. There was a strong seasonality with almost all species flowering and fruiting in spring and summer. Overall sexual reproduction coincided with an increase in day length in summer. Seed rain of several plant communities was measured across eight sites of differing environments. At most sites seed rain was representative of standing vegetation, with the most widespread and abundant species1 on the island being the most widespread and abundant species present in the seed rain. The study has shown that several species (particularly Pleurophyllum hookeri and Stilbocarpa polaris) produced large numbers of seeds (over 13, 300 seeds `m^-2`) which are greater seed rain densities than previously recorded in arctic and alpine studies. Both species of large leaved megaherb (P. hookeri and S. polaris) are abundant on the island. S. polaris and P. hookeri allocated resources similarly as both species were found to allocate over 50 % of their total biomass to leaf tissue and a substantial proportion of biomass (20+%) to sexual reproduction. The study identified that seed germination occurred for megaherbs across a range of altitudes. Seedling densities recorded for both species were extremely high (up to 10, 000 `m^2`). Despite high seedling mortality during the study many seedling were observed to survive to become juvenile plants. P. hookeri population demography was investigated across four different populations. All were found to be dominated by large old plants. Despite some demographic variation between populations, seedlings were recruited into the population at most sites. Alien species were found to have deleterious impacts on megaherb species through seed predation, seedling herbivory, and site disturbance. This study has shown that plants on subantarctic Macquarie I. allocated considerable resources to sexual reproduction which is an important plant life history strategy for plants growing in this environment.

description: Phosphorus-containing flame retardants synthesized from renewable resources have had a lot of impact in recent years. This article outlines the synthesis, characterization and evaluation of these compounds in polyesters and epoxy resins. The different approaches used in producing biobased flame retardant polyesters and epoxy resins are reported. While for the polyesters biomass derived compounds usually are phosphorylated and melt blended with the polymer, biobased flame retardants for epoxy resins are directly incorporated into the polymer structure by a using a phosphorylated biobased monomer or curing agent. Evaluating the efficiency of the flame retardant composites is done by discussing results obtained from UL94 vertical burning, limiting oxygen index (LOI) and cone calorimetry tests. The review ends with an outlook on future development trends of biobased flame retardant systems for polyesters and epoxy resins.

description: In many experimental situations, a physical system undergoes stochastic evolution which may be described via random maps between two compact spaces. In the current work, we study the applicability of large deviations theory to time-averaged quantities which describe such stochastic maps, in particular time-averaged currents and density functionals. We derive the large deviations principle for these quantities, as well as for global topological currents, and formulate variational, thermodynamic relations to establish large deviation properties of the topological currents. We illustrate the theory with a nontrivial example of a Heisenberg spin-chain with a topological driving of the Wess-Zumino type. The Cramér functional of the topological current is found explicitly in the instanton gas regime for the spin-chain model in the weak-noise limit. In the context of the Morse theory, we discuss a general reduction of continuous stochastic models with weak noise to effective Markov chains describing transitions between stable fixed points.

Sex-linked, recessive, cold-sensitive mutants of Drosophila melanogaster : genetic and biochemical studies
Creators: name: Mayoh, Helen Margaret
Publisher: name: University of British Columbia
Year: 2010

description: Cold-sensitive mutants of E. coli have been valuable in the study of the structure and assembly of bacterial ribosomes. Some cold-sensitive mutations of E. coli have been mapped to loci coding for ribosomal proteins. Other cold-sensitive mutations have been shown to alter the regulatory properties of bacterial enzymes. In contrast, little was known about the genetics and biochemistry of cold-sensitive mutants of Drosophila and other eukaryotes. Also, the genetic loci of ribosomal proteins of D. me1anogaster were unknown although the ribosomal RNA genes have been located on the X and 2nd chromosomes. Therefore the following questions were asked: Can cold-sensitive lethals of the X chromosomes of Drosophila melanogaster be isolated? If so, what are their genetic properties? Do some have altered ribosomal proteins as in cold-sensitive mutants of bacteria? The study was part of a general search for and characterization of cold-sensitive lethals of all the chromosomes of D. melanogaster. Among 3,919 EMS-treated X chromosomes, 25 were retained as cold-sensitive lethals or semi-lethals. That is, more than 20% of the flies carrying a cold-sensitive lethal survived at 22°C and none at 17°C, and for cold-sensitive semi-lethals, > 30% survived at 22°c and <13% at 17°c. The cold-sensitive mutations were not randomly distributed, 7 being located at the X tip and 3 being alleles to the right of car. Over half exhibited female sterility at the permissive temperature and 7 exhibited visible phenotypes characteristic of bobbed and Minute mutations. As the presence of altered ribosomal proteins has been demonstrated in cold-sensitive mutants of bacteria, the ribosomal proteins from Drosophila mutants and controls were studied by 2-dimensional gel electrophoresis. By this method, it was estimated that 69-72 proteins are present in the ribosomes of Drosophila. No qualitative differences were observed in the gel patterns of ribosomal proteins from 5 cold-sensitive, sex-linked mutants and the controls. A summary of the biochemical testing of the ribosomes from other cold-sensitive mutants of Drosophila is also given. No biochemical evidence to support the hypothesis that cold-sensitive mutants of Drosophila have altered ribosomes was obtained. The limitations of the study and recommendations for future research are discussed.

description: Unge bilister forbliver overrepræsenterede i trafikulykkesstatistikker. Bilisters evne til at identificere potentielle risikosituationer samt til at reagere adækvat i disse situationer forbedres gradvist baseret på erfaring med håndtering af en bred vifte af trafikale situationer. Internationalt betegnes denne evne ofte som hazard perception skills (HPS). Formålet med denne undersøgelse er at afdække, om yngre bilisters HPS i fodgængerrelaterede situationer kan forbedres gennem et specialdesignet træningsforløb, gennemført i en kørselssimulator. Træningsforløbet omfattede en kombination af træningskørsel i en kørselssimulator, en video med et lydspor med ekspertkommentarer vedr. bilkørsel samt en afspilning af deltagernes egen træningskørsel. 30 unge bilister modtog træning og deres resultater blev sammenlignet med 30 utrænede bilister. Sammenligningen blev baseret på deres visuelle fikseringer og køreadfærd i forskellige fodgængerrelaterede situationer af varierende kompleksitet. Resultaterne viste, at trænede bilister reagerede på en af tre skjulte farer ved at reducere hastigheden, mens utrænede bilister ikke gjorde. Analysen af deltageres visuelle fikseringer viste, at de trænede bilister oftere fikserede på steder, hvor farer kunne være skjult. Derudover havde trænede bilister en lavere selvvurderet HPS efter træningen end før træningen. Interventionen havde en positiv effekt med hensyn til at forbedre bilisternes kørehastighed og visuelle fikseringer i potentielt kritiske fodgængerrelaterede situationer, hvilket kræver mere avancerede HPS. Resultaterne tyder på, at interventionen med fordel kan videreudvikles med henblik på at implementere et ekstra modul, som led i den køreskolebaserede køreundervisning, for at sikre nye bilister de bedst mulige HPS, når de får kørekørt.

description: Design requirements for moving parts in mechanical assemblies are typically specified in terms of interactions with other parts. Some are purely kinematic (e.g., pairwise collision avoidance) while others depend on physics and material properties (e.g., deformation under loads). Kinematic design methods and physics-based shape/topology optimization (SO/TO) deal separately with these requirements. They rarely talk to each other as the former uses set algebra and group theory while the latter requires discretizing and solving differential equations. Hence, optimizing a moving part based on physics typically relies on either neglecting or pruning kinematic constraints in advance, e.g., by restricting the design domain to a collision-free space using an unsweep operation. In this paper, we show that TO can be used to co-design two or more parts in relative motion to simultaneously satisfy physics-based criteria and collision avoidance. We restrict our attention to maximizing linear-elastic stiffness while penalizing collision measures aggregated in time. We couple the TO loops for two parts in relative motion so that the evolution of each part's shape is accounted for when penalizing collision for the other part. The collision measures are computed by a correlation functional that can be discretized by left- and right-multiplying the shape design variables by a pre-computed matrix that depends solely on the motion. This decoupling is key to making the computations scalable for TO iterations. We demonstrate the effectiveness of the approach with 2D and 3D examples.

Thus, in order to solve it, it suffices to determine for a given Coxeter system (W,R) all Coxeter generating sets S of W which are contained in R^W, the set of reflections of (W,R). In this paper, we provide a further reduction: it suffices to determine all Coxeter generating sets S in R^W which are sharp-angled with respect to R.

Field administration and rural development in Bangladesh : the collector's role
Creators: name: Shawkat Ali, A. M. M
Publisher: name: University Of Tasmania
Year: 2023

description: This is a study on the role of the Collector in the process of rural development in Bangladesh within the conceptual framework of comparative field administration. The Collector occupies a pivotal position in field administration that is comparable to that of the Prefect. Research suggests that (a) the role of the Collector is bound up less with supporting stability than with generating popular enthusiasm for rural development and (b) the formal structure does not reveal the functions of the Collector in the sphere of rural development. Collector's role in rural development is alluded to in the literature of field administration but is yet to be researched. This role cannot be explained by static models of field administration or by an approach that views the Collector as a paradigm of political field administrator concerned with regulatory functions. Evidence suggests that the role has a continuity that is best explained by an analysis of the Collector's relationship with the rural development process in terms of interaction among national political leadership, the field administrative system and participation by the villagers. Chapter I deals with the origin of field administrative system and analyses the circumstances that led to the mix between regulatory and development functions. Chapter II analyses the crucial role played by the Collector in the process of building up institutional framework for rural development during the years 1950 to 1971. Chapter III describes the continuity of the Collector's role in rural development, the failed attempt to introduce District Governor system and the relationship between the Collectoral pattern and development ministries during the years 1976 to 1979. Chapter IV deals with the role of the Collector in evocating popular enthusiasm for voluntary participation in labour-intensive schemes between the years 1974 to 1979. Chapter V argues the case for a micro-level under-standing of the cruciality of the Collector's role in the process of rural development based on voluntary labour-utilisation strategy. Chapter VI explains the theme of incompatibility of the colonial pattern of field administration in generating popular enthusiasm for development in terms of its relationship with the rural society, summarises the major points from the perspective of comparative field administration and indicates the most recent trends with regard to the future role of the Collector.

description: Hot exozodiacal dust is dust in the innermost regions of planetary systems, at temperatures around 1000K to 2000K, and commonly detected by near-infrared interferometry. The phenomenon is poorly understood and has received renewed attention as a potential risk to a planned future space mission to image potentially habitable exoplanets and characterize their atmospheres (exo-Earth imaging) such as the Habitable Worlds Observatory (HWO). In this article, we review the current understanding of hot exozodiacal dust and its implications for HWO. We argue that the observational evidence suggests that the phenomenon is most likely real and indeed caused by hot dust, although conclusive proof in particular of the latter statement is still missing. Furthermore, we find that there exists as of yet no single model that is able to successfully explain the presence of the dust. We find that it is plausible and not unlikely that large amounts of hot exozodiacal dust in a system will critically limit the sensitivity of exo-Earth imaging observations around that star. It is thus crucial to better understood the phenomenon in order to be able to evaluate the actual impact on such a mission, and current and near-future observational opportunities for acquiring the required data exist. At the same time, hot exozodiacal dust (and warm exozodiacal dust closer to a system's habitable zone) has the potential to provide important context for HWO observations of rocky, HZ planets, constraining the environment in which these planets exist and hence to determine why a detected planet may be capable to sustain life or not.

description: This paper is devoted to the study of the random displacement model on $\R^d$. We prove that, in the weak displacement regime, Anderson and dynamical localization holds near the bottom of the spectrum under a generic assumption on the single site potential and a fairly general assumption on the support of the possible displacements. This result follows from the proof of the existence of Lifshitz tail and of a Wegner estimate for the model under scrutiny.

description: Parkeringspladser i tætte byområder er en eftertragtet vare, men udbuddet kan være knapt, bl.a. som følge af, at bilejerskabet og den generelle bilrådighed over de seneste år er steget, efter at have været svagt faldende i forlængelse af finanskrisen. Dette ses konkret ved, at der fx i 2016 er 16.000 flere privatbiler i København end der var i 2010. Alene i perioden 2015 til 2016 er der kommet 4.500 flere biler. Stigningen i antallet af biler har medført en generel stigning i parkeringsbelægningen, herunder er der kommet flere zoner med en teoretisk parkeringsbelægning på 100 % eller højere. For Københavns Kommune er det omkostningsfuldt at etablere nye parkeringspladser, da disse enten skal anlægges i konstruktion eller tilvejebringes ved at fjerne areal fra andre formål. Projekt Smart Parkering har som formål at sikre en bedre udnyttelse af parkeringspladserne, og det er derfor interessant at undersøge i hvilket omfang behovet for etablering af nye parkeringspladser kan reduceres, gennem en smartere og mere effektiv udnyttelse af den eksisterende parkeringskapacitet. Herved kan projektet medvirke til at fastholde parkeringsudbuddet eller frigøre areal til andre formål som eksempelvis cykelparkering, bynatur og klimatilpasning. Denne undersøgelse er gennemført som led i en førmåling af p-situationen, bilisternes tidsforbrug i forbindelse med afsøgning efter en ledig parkeringsplads, samt søgetrafikkens omfang.

Samtidig er der flere, som får bil, og der køres mere. Det betyder, at der efterspørges mere parkering. Især i Aarhus Midtby, hvor der er begrænset plads, er der pres på parkeringen – og her især gadeparkeringen. Både beboere, virksomheder, kunder og besøgende efterspørger mere parkering. Der er i dag næsten altid ledig parkeringskapacitet i Aarhus Midtby men den ledige kapacitet er hovedagligt i parkeringsanlæg mens der er mangel på parkeringspladser i boligområderne. Her bruges kapaciteten ofte af pendlere og besøgende da parkeringen i stor grad er gratis og dermed presses beboerne på deres parkering. Parkeringspolitikken skal derfor blandt andet understøtte at bilister med ærinde i Midtbyen kan køre direkte til et parkeringsanlæg, og derfra let gå til det relevante mål i Midtbyen. Desuden skal den sikre tilstrækkelig parkering til beboere i Midtbyen. Samtidig skal vi, jf. fortællingen om Aarhus, benytte vores gaderum til andet en parkering for at opnå det Aarhus som vi alle ønsker. For at opnå dette er der en række midler der tages i anvendelse; beboerparkering i hele Aarhus Midtby, udvidet område og tidsrum med betalingsparkering, differentieret priser på parkering for henholdsvis gadeparkering og parkering i anlæg m.m. Alt i alt er det den største ændring i kommunens parkeringspolitik siden 1999 hvor beboerparkeringsordningerne blev indført.

Liquid n-hexane condensed in silica nanochannels: A combined optical birefringence and vapor sorption isotherm study

description: The optical birefringence of liquid n-hexane condensed in an array of parallel silica channels of 7nm diameter and 400 micrometer length is studied as a function of filling of the channels via the vapor phase. By an analysis with the generalized Bruggeman effective medium equation we demonstrate that such measurements are insensitive to the detailed geometrical (positional) arrangement of the adsorbed liquid inside the channels. However, this technique is particularly suitable to search for any optical anisotropies and thus collective orientational order as a function of channel filling. Nevertheless, no hints for such anisotropies are found in liquid n-hexane. The n-hexane molecules in the silica nanochannels are totally orientationally disordered in all condensation regimes, in particular in the film growth as well as in the the capillary condensed regime. Thus, the peculiar molecular arrangement found upon freezing of liquid n-hexane in nanochannel-confinement, where the molecules are collectively aligned perpendicularly to the channels' long axes, does not originate in any pre-alignment effects in the nanoconfined liquid due to capillary nematization.

description: The Tile Assembly Model is a Turing universal model that Winfree introduced in order to study the nanoscale self-assembly of complex (typically aperiodic) DNA crystals. Winfree exhibited a self-assembly that tiles the first quadrant of the Cartesian plane with specially labeled tiles appearing at exactly the positions of points in the Sierpinski triangle. More recently, Lathrop, Lutz, and Summers proved that the Sierpinski triangle cannot self-assemble in the "strict" sense in which tiles are not allowed to appear at positions outside the target structure. Here we investigate the strict self-assembly of sets that approximate the Sierpinski triangle. We show that every set that does strictly self-assemble disagrees with the Sierpinski triangle on a set with fractal dimension at least that of the Sierpinski triangle (roughly 1.585), and that no subset of the Sierpinski triangle with fractal dimension greater than 1 strictly self-assembles. We show that our bounds are tight, even when restricted to supersets of the Sierpinski triangle, by presenting a strict self-assembly that adds communication fibers to the fractal structure without disturbing it. To verify this strict self-assembly we develop a generalization of the local determinism method of Soloveichik and Winfree.

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2018

description: Modern railway signal systems allow the collection of very large data sets (more than a thousand values). These data sets are often rounded by the signal technology, so that the values are effectively discrete. This paper reviews other literature on fitting distributions to large data sets, and then shares the experience of distribution fitting to a large data set from the Danish railways.

Faktorer som påvirker fergereisendes ventetid

Year: 2018

description: I denne artikkelen presenteres en modell som beskriver hvordan ulike faktorer påvirker ventetiden til fergereisende. Anslagene er basert på intervjuer av 10 952 fergereisende som i 2013 ble gjennomført på seksten av de viktigste fergeforbindelsene i Norge. Modellenes resultater viser at brukerens ventetid ved terminaler øker konkavt med lengden på tidsintervallet mellom hver fergeavgang (headway), og avstanden respondenten hadde reist for å komme til fergeterminalen, noe som betyr at marginalvirkningen av disse faktorene reduseres når verdiene øker.

Observations of lacustrine sedimentation at Lillooet Lake, British Columbia
Creators: name: Gilbert, Robert
Publisher: name: University of British Columbia
Year: 2010

description: Sediment from Lillooet River basin, 3000 km² of alpine and subalpine landscape about 10% of which is glacierized, is largely deposited in Lillooet Lake. Dissolved sediment concentration in the streams flowing into Lillooet Lake is generally less than 100 mg l⁻¹. Suspended sediment concentrations vary from 50 mg l⁻¹ to over 3000 mg l⁻¹, related closely to water discharge. Coarse grained sediment which moves as bed load is deposited as foreset beds at the delta lip. Suspended sediments are distributed through the lake (a) by dispersion and interflow above the thermocline at low to moderate inflow rates and (b) by interflow and underflow at higher inflows. The thermocline effectively limits vertical sediment movement during much of the melt season though during high flows the thermal structure of the lake may be temporarily destroyed by underflow and powerful interflow. The delta surface consists of rapidly shifting channels and sand bars. Bed load movement is sporadic and changing lake levels lead alternately to accumulation in backwater when the lake level rises or flushout as the lake level falls. Coarse sediment from bed load, deposited on the proximal, slope is redistributed by infrequent major slump events. Mounds of slumped material cover the foreset slope to its base at 120 m depth. Interflow and underflow give rise to a distinctive sedimentary sequence of varved silts and clays interspaced with turbidites. Thickness of the varves is related to characteristics of the inflowing water and fine grained sediment. Continuous records of water temperature near the lake bottom indicate that frequent laminae within varves are due to intermittent underflow of suspended fluvial sediment. Autumn floods result in the deposition from suspension in the lake water of an anomalously thick, fine grained layer during the following winter. Infrequent much smaller winter inflow peaks result in underflow and the deposition of a lighter toned, coarser grained lamina in the winter deposit. Both are useful stratigraphic markers. Continuous seismic profile records indicate that as much as 200 m of sediment has been deposited in the lake. Calculation based on present rates of accumulation of 20 - 50 mm yr⁻¹, depending on distance from the delta, indicates that reflecting horizons in the sediment represent increased sediment input associated with volcanic activity 2400 years B.P. and, less reliably, to Pleistocene glaciation. Annual long term (1913-1969) clastic sediment yield at Lillooet Lake is calculated as 1.1 x 10⁶m³yr⁻¹ (specific denudation 0.28 mm yr⁻¹). The advance rate of Lillooet Delta indicates that yield may have trippled after 1950 associated with river engineering, logging and agriculture.

BFKL and CCFM evolutions with saturation boundary
Creators: name: Avsar, Emil

Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We perform numerical studies of the BFKL and CCFM equations for the unintegrated gluon distribution supplemented with an absorptive boundary which mimics saturation. For the BFKL equation, this procedure yields the same results for the saturation momentum and the gluon distribution above saturation as the non-linear BK equation, for both fixed and running coupling, and for all the considered energies. This similarity goes beyond expectations based on the correspondence with statistical physics, which hold only for fixed coupling and asymptotically high energies. For the CCFM equation, whose non-linear generalization is not known, our method provides the first study of the approach towards saturation. We find that, in the running-coupling case, the CCFM and BFKL predictions for the energy dependence of the saturation momentum are identical within our numerical accuracy. A similar saturation boundary could be easily implemented in the CCFM-based Monte Carlo event generators, so like CASCADE.

Vehicle Delay-Driven Passenger Delay Modelling
Creators: name: Paulsen, Mads
name: Rasmussen, Thomas Kjær
name: Nielsen, Otto Anker
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2018

description: Travel time of passengers is often uncertain due to lack of punctuality of public transport services. Whereas Automatic Vehicle Location (AVL) data makes it easy to measure the punctuality of public transport vehicles themselves, calculating door-to-door passenger punctuality is challenging, as both the intended and realised routes of passengers have to be considered. This study introduces a MATSim mesoscopic simulation framework for evaluating passenger punctuality caused by vehicle delays in the railway system in the metropolitan area of Copenhagen. Based upon empirical train delay data for 65 weekdays in the autumn of 2014, the model shows that passenger punctuality is considerably smaller than train punctuality, with 17.8% of the passengers using the railway system being delayed more than a minute compared to their intended plan.
