description: Irradiation cis-[M(Ln-S,O)2] complexes (M = PtII, PdII) derived from N,N-dialkyl-N′-benzoylthioureas (HLn) with various sources of intense visible polychromatic or monochromatic light with λ < 500 nm leads to light-induced cis → trans isomerization in organic solvents. In all cases, white light derived from several sources or monochromatic blue-violet laser 405 nm light, efficiently results in substantial amounts of the trans isomer appearing in solution, as shown by 1H NMR and/or reversed-phase HPLC separation in dilute solutions at room temperature. The extent and relative rates of cis/trans isomerization induced by in situ laser light (λ = 405 nm) of cis-[Pd(L2-S,O)2] was directly monitored by 1H NMR and 195Pt NMR spectroscopy of selected cis-[Pt(L-S,O)2] compounds in chloroform-d; both with and without light irradiation allows the δ(195Pt) chemical shifts cis/trans isomer pairs to be recorded. The cis/trans isomers appear to be in a photo-thermal equilibrium between the thermodynamically favored cis isomer and its trans counterpart. In the dark, the trans isomer reverts back to the cis complex in what is probably a thermal process. The light-induced cis/trans process is the key to preparing and isolating the rare trans complexes which cannot be prepared by conventional synthesis as confirmed by the first example of trans-[Pd(L-S,O)2] characterized by single-crystal X-ray diffraction, deliberately prepared after photo-induced isomerization in acetonitrile solution.

description: Som en del af de samfundsøkonomiske beregninger af vejprojekter indgår behovet for at opgøre eksterne effekter i form af uheld, emissioner, luftforurening og støjbelastning. Vejdirektoratet har i forbindelsen med en række planlægningsopgaver, herunder for- og VVM-undersøgelser, et behov for at opgøre de eksterne effekter på en ensartet måde. I samarbejde med MOE | Tetraplan, er der derfor udviklet en model, der på baggrund af resultater fra trafikale beregninger med Landstrafikmodellen (LTM), beregner de eksterne effekter for vejtrafikken som følge af et vejinfrastrukturprojekt. Modellen, der er blevet navngivet LTMEnvi, tager udgangspunkt i eksisterende beregningsmetoder til fastlæggelse af trafikkens eksterne effekter, og kobler metoderne med data fra LTM i form af trafikale beregningsresultater og andre grunddata samt en række øvrige eksterne kilder, hvoraf flere er i GIS-format. Resultaterne fra modellen kan udtrækkes både i form af tabeller og geografiske kort, og som en samlet opgørelse af nøgletal fra beregningerne til brug for samfundsøkonomiske beregninger med Teresa-modellen. Der er foretaget en kvalitetssikring og validering af de overordnede nøgletal, der er sammenholdt med eksisterende kilder, som overordnet giver god overensstemmelse mellem resultaterne fra LTMEnvi beregningerne og de eksterne kilder.

description: A relativistic diffusion model with cylindrical symmetry, which propagates an initial state based on quantum chromodynamics in time towards a thermal equilibrium limit, is derived from nonequilibrium-statistical considerations: Adapting an existing framework for Markovian stochastic processes representing relativistic phase-space trajectories, a Fokker-Planck equation is obtained for the time evolution of particle-number distribution functions with respect to transverse and longitudinal rapidity. The resulting partially-evolved distribution functions are transformed to transverse-momentum and pseudorapidity space, and compared with charged-hadron data from the CERN Large Hadron Collider (LHC).

description: This paper studies the importance of transportation for the quality of life in Denmark. The average Dane spends about 55 minutes on transport per day (DTU [2013]) and the average household's expenditure devoted to transport is about 20 % of the total household budget (Berri et al. [2014]).1 It is therefore important to recognize the importance of transportation for the quality of life. Transportation is derived demand as individuals often consume the service not because they benet from consumption directly, but because they partake in other consumption or activities elsewhere (see e.g. Small and Verhoef [2007]). Transportation allows households to buy consumption goods and activities, get to work and enjoy leisure. Households therefore face in general trade-o between, on one hand productivity and consumption advantages (high-paying jobs and high quality local urban amenities), and on the other hand higher costs of living and dis-amenities (high housing costs, congestions and pollution), when they decide where to live. Transportation infrastructure facilitates interaction within cities. It relieves pressure on urban land by enabling workers to live at some distance from their jobs at reasonable commutes. Transport infrastructure thus aect the attractiveness of urban areas. We construct a transport adjusted Quality of Life Index (QLI) for the 98 urban areas - municipalities - covering Denmark. Using this index we investigate the importance of adjusting for the inter area commute patterns in terms of the quality of life of a typical household. We also investigate the relationship between transport infrastructure investments and the QLI.

description: We present a numerical study, using the vortex filament model, of vortex tangles in a flow of pure superfluid $^4$He in the $T = 0$ limit through a channel of width $D = 1$ mm for various applied velocities $V$. The flat channel walls are assumed to be microscopically rough such that vortices terminating at the walls are permanently pinned; vortices are liberated from their pinned ends exclusively through self-reconnection with their images. Sustained tangles were observed, for a period of 80 s, above the critical velocity $V_c \sim 0.20$ cm s$^{-1} = 20 κ/D$. The coarse-grained velocity profile was akin to a classical parabolic profile of the laminar Poiseuille flow, albeit with a non-zero slip velocity $\sim$ 0.20 cm s$^{-1}$ at the walls. The friction force was found to be proportional to the applied velocity. The effective kinematic viscosity was $\sim 0.1κ$, and effective Reynolds numbers within $\mathrm{Re'} < 15$. The fraction of the polarized vortex length varied between zero in the middle of the channel and $\sim$ 60% within the shear flow regions $\sim D/4$ from the walls. Therefore, we studied a state of polarized ultraquantum (Vinen) turbulence fuelled at short lengthscales by vortex reconnections, including those with vortex images due to the relative motion between the vortex tangle and the pinning rough surface.

Udfordringer ved samfundsøkonomisk analyse af transportprojekter
Creators: name: Andersen, Knud Erik
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2019

description: Den samfundsøkonomiske analyse har til formål at støtte den politiske beslutningsproces. Men der er langt imellem, at der ved politiske valg eller fravalg af projekter henvises til samfundsøkonomisk rentabilitet. Produktivitetskommissionen gjorde allerede for nogle år siden opmærksom på et alvorligt problem i transportsektoren med en stor andel af samfundsøkonomisk ineffektive investeringer. Eksperter udvikler til stadighed metodiske forbedringer og finjusteringer af den samfundsøkonomiske beregning. Der foreligger nu et helt system af korrektionsfaktorer, og flere er undervejs. Men det burde disku-teres med aftagerne - dvs. politikerne - hvad det er, der skal til, for at analyserne får en politisk mere brugbar form. Politikerne efterspørger ikke nødvendigvis beregninger, der omfatter flest mulige politiske hensyn. Det kan endda tværtimod være mere enkelhed, der skal til for at fremme anvendelsen. Grundlæggen-de ønsker en politiker næppe at få sat hele sin beslutningsproces på formel. Eksperterne bør derfor også tænke i anvendelighed frem for at forsøge at afspejle flest mulige politiske og fiskale hensyn. De anvendte beregninger bør derudover have større fokus på helt grundlæggende analyse- og beregningskvalitet. Ved enhver samfundsøkonomisk analyse relateres et projektscenarie til et basisscenarie. Sidstnævnte behandles imidlertid ofte stedmoderligt. Men et projektscenarie skal jo ofte, set over en lang planperiode, afløse komplicerede og måske dynamisk udviklende uhensigtsmæssigheder i transportsystemet dvs. afgørende og ofte modelberegnede karakteristika ved basisalternativet. Basisalternativet kan også have sin egen specielle anlægs- og driftsøkonomi. Derer ikke nødvendigvis bare tale om et ’nul-alternativ’, og basisalternativet kan også være karakteriseret af teknologiske og markedsmæssige udviklinger af stor betydning. Samlet set indebærer det, at basisscenariet bør have mindst lige så meget fokus som projekt-scenariet – om ikke mere. Det største forbedringspotentiale for den samfundsøkonomiske analyse er således at levere politisk rele-vante og kommunikérbare nøgletal og sætte fokus på, at helt grundliggende beregninger er retvisende. Først derefter bør man tænke i metodemæssige finjusteringer.

Radio spectra of pulsars fitted with the spectral distribution function of the emission from their current sheet

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: In their catalogue of pulsars' radio spectra, Swainston et al. (2022, PASA, 39, e056) distinguish between five different forms of these spectra: those that can be fitted with (i) a simple power law, (ii) a broken power law, (iii) a low-frequency turn-over, (iv) a high-frequency turn-over or (v) a double turn-over spectrum. Here, we choose two examples from each of these categories and fit them with the spectral distribution function of the caustics that are generated by the superluminally moving current sheet in the magnetosphere of a non-aligned neutron star. In contrast to the prevailing view that the curved features of pulsars' radio spectra arise from the absorption of the observed radiation in high-density environments, our results imply that these features are intrinsic to the emission mechanism. We find that all observed features of pulsar spectra (including those that are normally fitted with simple or broken power laws) can be described by a single spectral distribution function and regarded as manifestations of a single emission mechanism. From the results of an earlier analysis of the emission from a pulsar's current sheet and the values of the fit parameters for each spectrum, we also determine the physical characteristics of the central neutron star of each considered example and its magnetosphere.

description: ABSTRACTPoly(amidoamine) dendrimer (PAMAM) was successfully functionalized by chlorosulfonic acid to form an strong ionic acid catalyst. The resulting polymeric catalyst was shown to be an efficient catalyst for the synthesis of 1,1-diacetyl from aldehydes under free solvent conditions at room temperature. Also, the deprotection of the resulting aldehydes was investigated under catalytic conditions. The Hammett acidity function of catalyst showed that catalyst is a strong Brønsted acid. Due to the multi-functional nature of PAMAM, the catalyst has high loading level of acidic protons.
Multiple localized-itinerant dualities in magnetism of 5f electron systems. The case of UPt$_2$Si$_2$

description: The paper deals with the U based compound UPt$_2$Si$_2$ (UPS). The material was first treated as a localized 5f-electron system. Later, an opposite opinion of a predominantly itinerant nature of the system was put forward. The most recent publications treat UPS as a dual material. We suggest a material specific theoretical model based on the density functional theory plus Hubbard $U$ (DFT+$U$) calculations that describes the set of fundamental ground-state properties and high magnetic field experiment. The ground state properties include antiferromagnetic magnetic structure, magnetic easy axis, and the value of the U atomic moment. The in-field experiment shows the presence of a strong metamagnetic transition for the field parallel to the easy axis in contrast to the hard field direction where such a feature is absent. On the other hand, comparable induced magnetization values are obtained for both easy and hard field directions. Within the framework of the suggested model we show that the compound possesses well-formed atomic moments built by electrons treated as delocalized. To understand the experimental high-field properties we estimate exchange energy, magnetic anisotropy energy, and Zeeman energy. All three energies are shown to have comparable values what is crucial for the interpretation of the experiment. At all steps of the study we devote special attention to revealing and emphasizing the dual itinerant-localized properties of the material. The obtained forms of the duality are different: well defined atomic moments formed by the itinerant electrons, interplay of the single-site and two-site anisotropies, strong localization of two of the 5f electrons in contrast to the itinerant nature of the 5f electrons contributing to the states around the Fermi level.

description: We consider the Dirac field in polar formulation, showing that when torsion is taken in effective approximation the theory has the thermodynamic properties of a van der Waals gas, that when the limit of zero chiral angle is taken the theory reduces to that of a Weyssenhoff fluid, and that under the spinless condition it gives the Newtonian particle. This nesting of approximations will allow us to interpret the various objects pertaining to the spinor, with torsion providing a form of negative pressure, and the chiral angle being related to a type of temperature.

description: During recombination, the cosmic background radiation is disturbed, in particular, by Lyman-alpha emissions from neutral hydrogen. It is proposed to account for the subsequent time-dependent partial thermalization of the Lyman-alpha energy content in an analytically solvable nonlinear diffusion model. The amplitude of the partially thermalized and redshifted Ly-$α$ line is found to be too low to be visible in the cosmic microwave spectrum, in accordance with previous numerical models and Planck observations.

En transportpolitikk med usynlige virkninger for trafikksikkerheten?
Creators: name: Elvik, Rune
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University

description: Et mål for transportpolitikken mange steder er at flere skal gå eller sykle eller reise med kollektive transportmidler. Argumentene for dette er blant annet å bedre folkehelsen og å redusere klimagassutslipp fra transport. Det er imidlertid meget sannsynlig at økt ferdsel til fots, med sykkel eller med kollektive transportmidler vil øke antallet personskader i trafikken. Det er videre overveiende sannsynlig at det meste av økningen i antall skader ikke vil bli registrert i offisiell ulykkesstatistikk. Man kan godt tenke seg at den offisielle ulykkesstatistikken kun vil vise en liten, eller ingen, økning i antall skadde trafikanter når flere går, sykler eller reiser kollektivt. De virkelige skadetallene er langt høyere enn ulykkesstatistikken viser. Rapporteringsgraden for skader blant syklister er under 10 %. De fleste skader blant fotgjengere inntreffer ved fallulykker som ikke er definert som trafikkulykke. Videre oppstår de fleste skader blant reisende med kollektive transportmidler ved fall ombord eller ved av- og påstigning; hendelser som heller ikke betraktes som trafikkulykker. I denne artikkelen er det laget regne-eksempler på mulige virkninger på antall skadde personer av økt gange, sykling og bruk av kollektive transportmidler basert både på skaderisiko beregnet på grunnlag av offisiell statistikk og basert på skaderisiko beregnet på grunnlag av skader registrert av helsevesenet. Vesentlig mindre enn 10 % av den reelle økning i skadetall vil synes i offisiell ulykkesstatistikk.

description: Trafitec har for Vejdirektoratet udviklet metoder til systematiske opgørelser af bilisters oplevede serviceniveau på strækninger af by- og landeveje. Resultater af sådanne opgørelser beskriver, hvor tilfreds bilister er på en vej eller et vejnet. Til at beskrive hvordan trafikafvikling, vejdesign og andre forhold påvirker bilisters tilfredshed, har 268 tilfældigt udvalgte respondenter set 144 videoklip af vejstrækninger optaget fra en kørende personbil. Videoklippene er udført i HD-format med kameradækning ud af forrude, ved sidespejle/sideruder og ud af bagrude samt et GPS-baseret speedometer. Respondenter har vurderet videoklip på en tilfredshedsskala med 6 trin gående fra meget tilfreds til meget utilfreds. I alt er der indsamlet 2.757 tilfredshedsvurderinger af 48 videoklip fra 36 veje i byer og 2.757 tilfredshedsvurderinger af 48 videoklip fra 36 landeveje. Hvert videoklip og vejstrækning er beskrevet med ca. 450-500 variable, der angiver trafikafvikling, vejudformning, omgivelser, vejr, osv. Der er opstillet to typer modeller, der beskriver sammenhænge mellem bilisters tilfredshed og forholdene på by- og landeveje. Både kumulative logit modeller og generaliserede lineære modeller indeholder kun statistisk signifikante variable, der påvirker bilisters tilfredshed på logisk facon. Det er hovedsageligt den gennemsnitlige rejsehastighed og hastighedsbegrænsningen, der påvirker bilisters tilfredshed på by- og landeveje. Derudover påvirkes tilfredsheden i mindre grad af antallet af fodgængere og parkerede biler, vejens længdeprofil, bredden af kørebane, midterrabat og fortov samt typen af cykelfacilitet og kantlinje. Den kumulative logit model returnerer den procentuelle fordeling af bilister på de 6 tilfredshedskategorier og dette oversættes efterfølgende til oplevet serviceniveau.

description: Thesis Artifacts for: Thesis Artifacts for: Collaborative Program Comprehension based on Virtual Reality A detailed description can be found in the README.md. The corressponding thesis can be found here. Abstract To meet the increasing requirements of modern computer programs, the complexity of software systems is constantly growing. Monitoring tools, especially tools for software visualization, help to handle this complexity and to gain a deep understanding of the structure and the runtime behavior of software systems. The VR extension of the research tool ExplorViz provides an approach to collaboratively exploring large software landscapes using virtual reality. A first practical test has shown that the tool meets the basic usability requirements. The aim of this thesis is to investigate whether the VR extension is suitable for collaboratively solving complex tasks in the context of program comprehension. For this purpose we extended the VR extension with a number of features that increase the information offer and enhance the possibilities of interaction. Subsequently, we conducted an experiment with 24 participants, in which software analysis tasks were to be solved in teams. The results show that the VR extension is well suited for collaboratively analyzing both static and dynamic aspects of software systems. However, the experiment also revealed problems in navigation and layout.

description: While first-principles calculations of electrode-molecule binding play an indispensable role in obtaining atomic-level understanding in surface science and electrochemistry, a significant challenge remains because the adsorption energy is well-defined only in equilibrium. Herein, a theory to calculate the electric enthalpy for electrochemical interfaces is formulated within the multi-space constrained-search density functional theory (MS-DFT), which provides the nonequilibrium total energy of a nanoscale electrode-channel-electrode junction. An additional MS-DFT calculation for the electrode-only counterpart that maintains the same bias voltage allows one to identify the internal energy of the channel as well as the electric field and the channel polarization, which together determine the electric enthalpy and the nonequilibrium adsorption energy. Application of the developed scheme to the water-Au and water-graphene interface models shows that the Au and graphene electrodes induce very different behaviors in terms of the electrode potential-dependent stabilization of water configurations. The theory developed here will be a valuable tool in the ongoing effort to obtain an atomic-scale understanding of bias-dependent molecular reorganizations in electrified interfaces.

Offentligt Privat Partnerskab − Perspektiverne for den kollektive trafik
Creators: name: Darmer, Michael
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2004

description: Som trafikplanmyndighed i Hovedstadsregionen undersøger HUR mulighederne for at anvende OPP i forbindelse med større trafikprojekter i regionen. Baggrunden er, at der er udsigt til at trafikinvesteringerne i Hovedstadsregionen vil falde de kommende år, medmindre der findes alternative finansieringskilder. Et fald kan få betydning for den økonomiske vækst i regionen, udviklingsmulighederne samt velfærd og miljø. HUR ser OPP som et spændene alternativ til traditionel offentlig finansiering. Konceptet indebærer en række fordele for det offentlige, først og fremmest at OPP-projekter oftere leveres til tiden og inden for budget sammenlignet med traditionelle projekter. Samtidig er OPP en enorm udfordring for den offentlige myndighed. Særligt de indledende stadier - dvs. udbuds og kontraktskrivningsfasen vil stille store og nye krav til det offentlige. Også det mangeårige partnerskab byder på udfordringer - kulturforskelle mellem offentlig og privat, vil politikerne acceptere et reduceret politisk og økonomiske råderum over projektet osv. OPP kræver at den offentlige aktør har en solid kompetence på området - tillid kræver respekt og respekt kræver viden. Større OPP-projekter inden for infrastruktur og lignende kan derfor med fordel forankres i de kommende regioner eller stat.

description: Samferdselsmyndighetene i Norge har engasjert Transportøkonomisk Institutt (TØI) og Møreforsking Molde AS (MFM) til å etablere et sett med landsdekkende kortdistanse transportmodeller som blant annet skal benyttes i arbeidet med nasjonal transportplan (NTP). Grunnlaget for arbeidet er blant annet en nasjonal reisevaneundersøkelse gjennomført i Norge i 2001 (RVU2001), og en rekke andre geografisk fordelte data fra samme tidsrom. RVU2001 og de øvrige data er stedfestet til grunnkretser som geografisk enhet. Det er vel 13500 slike grunnkretser i Norge. Modellene omfatter bilhold/førerkortinnehav, innehav av periodekort for kollektivtransport, valg av transportmiddel og destinasjon, og reisefrekvens. Det er også utviklet en prosedyre som ivaretar reiser med sekundære destinasjoner. Det er estimert modeller på data for hele landet og modellene skal implementeres i 5 regioner.

Forecasting the Trade Flow of Denmark
Creators: name: Lyk-Jensen, Stéphanie Vincent
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2004

description: This paper presents the modeling of a dynamic gravity equation in order to forecast the trade flows of goods in and out of Denmark, including transit goods. This analysis is part of a research project where the objective is to establish the future flow of goods for Denmark as well as the node points in order to be able to optimize public investments. The paper only focuses on the construction of the gravity equation that will be used for setting up scenarios for the future flow of goods from and to Denmark. We compare different methods of estimation of the gravity equation used in previous studies and propose a robust estimation of a dynamic gravity equation. Examples of the forecasting method are presented for illustration.

Explaining the decoupling of freight traffic growth and economic growth
Creators: name: Kveiborg, Ole
name: Fosgerau, Mogens
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2004

description: In recent years we have in many European countries seen a decoupling of the growth in freight traffic (vehicle km) from economic growth. A similar decoupling has not been seen in freight transport (tons km). In this paper we analyse the historical development in freight transport and freight traffic using a decomposition methods described in Fosgerau and Kveiborg (2004). The growth in freight traffic can be attributed to various factors with economic growth as an important factor, but there are also important explanations caused by the development in vehicle size, average load and average length of trips as well as the logistical element of freight transport described by the handling factor, which links produced amounts in tons to tons conveyed. Through the analysis we point out the impact these factors have on overall development in freight traffic and freight transport. We further demonstrate that overall freight traffic growth is a consequence of often opposite pointing growth effects in the underlying factors. We find that the primary reason for the decoupling of freight traffic growth and economic growth can be attributed to growth in vehicle sizes, increasing average load and less empty running with the vehicles.

description: Polycaprolactone (PCL)/hydroxyapatite (HA) composite scaffolds were prepared by combining solvent casting and salt particulate leaching with a polymer leaching technique. The hydrophilicity of the dual-leached scaffold was improved by alkaline (NaOH) treatment. Well-defined interconnected pores were detected by scanning electron microscopy. The water absorption capacity of the NaOH-treated PCL/HA dual-leached scaffold increased greatly, confirming that the hydrophilicity of the scaffold was improved by NaOH treatment. The compressive modulus of the PCL/HA dual-leached scaffold was greatly increased by the addition of HA particles. An indirect evaluation of the cytotoxicity of all PCL dual-leached scaffolds with mouse fibroblastic cells (L929) and mouse calvaria-derived pre-osteoblastic cells (MC3T3-E1) indicated that the PCL dual-leached scaffolds are non-toxic to cells. The ability of the scaffolds to support mouse calvaria-derived pre-osteoblastic cell (MC3T3-E1) attachment, proliferation, differentiation, and mineralization was also evaluated. Although the viability of cells was lower on the PCL/HA dual-leached scaffold than on the tissue-culture polystyrene plates (TCPS) and on the other substrates at early time points, both the PCL and NaOH-treated PCL/HA dual-leached scaffolds supported the attachment of MC3T3-E1 at significantly higher levels than TCPS. During the proliferation period (days 1–3), all of the PCL dual-leached scaffolds were able to support the proliferation of MC3T3-E1 at higher levels than the TCPS; in addition, the cells grown on NaOH-treated PCL/HA dual-leached scaffolds proliferated more rapidly. The cells cultured on the surfaces of NaOH-treated PCL/HA dual-leached scaffolds had the highest rate of mineral deposition.
