Elbiler i København. ZEUS-projektet
Creators: name: Jensen, Niels
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 1999

description: København anskaffer ca. 50 elbiler. Det sker som et led i ZEUS-projektet under EU's Ther-mieprogram. København har sammen med 4 andre byer været ude i en EU-licitation og har som resultat heraf forpligtiget sig til at anskaffe 10 Citroën Berlingo CityVan Electrique og 10 Fiat Seicento Elettra. Berlingo’erne blev købt og fungerede fint, men det viste sig desværre, at Fiat'erne ikke kunne leve op til de krav der var stillet til rækkevidde. Kommunen frigjorde sig derfor fra kontrak-ten. Heldigvis var det muligt at købe Citroën Saxo Electrique i stedet for Fiat’erne. I juli 1999 havde kommunen anskaffet 20 Berlingo, 17 Saxo samt 6 specielle arbejdskøretøjer. Bilernes ydeevne, under de meget forskellige klimatiske og topografiske forhold i ZEUS-byerne, skal evalueres af det engelske motorprøveinstitut MIRA. Foreløbige resultater fra Kø-benhavn viser, at elbilerne indtil videre lever op til forventningerne. Mange kommunale biler kører ikke mere end 40-50 km om dagen og kan uden videre erstattes af elbiler. Opladningen kan foregå om natten, hvorved elbiler kun bruger omkring halvdelen af den energi konventionelle biler bruger. Der er lejlighedvis et behov for opladning i løbet af dagen. Københavns kommune har tre ste-der hvor det - også for private - er muligt at lade bilerne op. Opladning er for tiden gratis og der er ingen parkeringsafgift for elbiler i København.

The Øresund Traffic Forecast Model

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2002

description: The Øresund Traffic Forecast Model was designed to forecast impacts of the fixed link crossing Øresund. The link connects the metropolitan area of Copenhagen with Malmö – the third largest city in Sweden. The link provides a direct rail and car connection between the two city-centres, previously only served by fast passenger boats. The latter was not connected to the rail network of Copenhagen, and parking facilities in Copenhagen near the boat was few and expensive. On the other hand several other ferry-lines connected other parts of the Copenhagen Region with the southern Sweden. Accordingly, the fixed link improved the connection between the two regions significantly – but to a varying extent for different parts of the region. The fixed link also improved the infrastructure for longer trips between the Scandinavian Peninsula and the European Continent. However, in this respect the link compete with quite a number of ferry links. From a modelling point of view, the task was difficult since the choice set included many overlapping routes and (sub-) mode-choices. For some trips, the link constitutes a significant improvement. But the link connects two countries, where culture, language and economy (e.g. labour legislation) provide a potential barrier for travel. Economic differences may also results in additional trips, e.g. shopping trips due to different VAT- and tax-levels on different goods. To model this context, tenders were invited for a large-scale traffic model project. The resulting model was in many respects state-of-the-art: A utility-based model (nested logit) was estimated from joint RP- and SP-datasets collected specifically for the study. Several sub-models (segments) were estimated for short- and long trips, and for different trip purposes. In addition, both passenger and freight traffic were described by different (sub) models. However, in reality the model failed to describe several impacts of the fixed link (as it turned out after the link opened). Especially, the model failed to describe the competition between fast boats and the rail link, and the magnitude of the social and economic barriers for short-distance traffic. Since the model itself is described in Øresundskonsortiet (2000) its structure is only briefly described in section 2 of the present paper. Accordingly, the main focus is on lessons learned from the model project, starting with a short description of the forecast results versus actual traffic in section 3. Section 4 describes different modelling issues that are considered as the main problem with conventional models. Finally, section 5 sums up the conclusions and provide some guidelines for future models of projects that involve a mixture of regional and international (long-distance) traffic.

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2002

description: When evaluating large infrastructure projects one point to be made is the importance of supplementing the more traditional effects captured by a cost-benefit analysis as presented for example by use of the benefit cost ratio (BCR) with strategic effect modelling to obtain a more comprehensive view of the societal importance of the examined project. The focus of this paper is to present the first results of a comparison of the use of a strategic impact measurement (the POINTER index) for road traffic on the Great Belt Link, the Øresund Link and the proposed Fehmarn Belt link. Specifically a number of calculation scenarios have been made to assess the possibility of the POINTER approach to indicate the changes in strategic mobility (accessibility) associated with the implementing of one or more of the three fixed links. Finally, conclusions and a research perspective are outlined.

description: The External Ligurian and Epiligurian Units in the Northern Apennines of Italy are tectonically juxtaposed with the Tertiary Piedmont Basin along the Villalvernia – Varzi Line, which represents a regional scale fault zone, E-striking. Our map, at the 1:20,000 scale, describes the tectono-stratigraphic evolution of this sector that resulted from multistage faulting along that fault zone. Four main tectonic stages are defined on the basis of the crosscutting relationships between mapped faults and stratigraphic unconformities: late Priabonian – Rupelian, Chattian – early Miocene, late Serravallian – Tortonian, and late Messinian – early Pliocene. Our results demonstrate that since the late Burdigalian, the Villalvernia – Varzi Line was sealed by the gravitational emplacement of a chaotic rock body. The deposition of the late Serravallian – early Messinian succession is controlled by NW-striking strike-slip faults that crosscut to the west the Villalvernia – Varzi Line. Extensional tectonics related to regional scale N-dipping tilting characterized the late Messinian – early Pliocene time interval.

Fiscal measures to Reduce CO2 emissions from new passenger cars
Creators: name: Jordal-Jørgensen, Jørgen
name: Jespersen, Malene Sand
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2002

description: The fuel efficiency of passenger cars is often emphasised as one of the most significant areas of action in terms of limiting the transport sector’s CO2 emission levels. This could be achieved either on the supply side through the technological development of cars, or through demand-side measures such as influencing first time buyers’ choice of car. The aim of this article is to present a model for analysis of the demand side, more specifically the relation between the CO2 emissions from new cars and the car taxation related to new car purchases in EU. The purpose of the model is twofold. Firstly, it should be used to analyse the CO2 efficiency of the car taxation in each member state. Secondly, results from model calculations should be used to illustrate what are the possibilities for the individual member states to reduce their CO2 emissions from new cars. The major conclusions from the study are: • It is essential to apply a tax scheme, which is directly or indirectly CO2 related in order to provide for significant reductions in the average CO2 emissions from new cars. • It is essential to differentiate the taxes in such a way that taxes for very energy effective cars are significantly lower than taxes for cars with poor energy efficiency. • Fuel tax increases provide only very small reductions of the average CO2 emissions of new cars compared to vehicle taxes. The model is based on a revised and enhanced version of the Danish Car Choice model from 1997 combined with car characteristics, socio-economic data and car taxation data from the EU member states.

description: The research presented in this report is the second project of ongoing research on this subject at the University of Texas and is focused on in-situ remediation of dense chlorinated contaminants in the subsurface. The purpose of the first project was to find the most effective oxidation/reduction (redox) catalyst combination to dehalogenate TCE to less hazardous products. The focus of this second project is to test the selected redox catalyst, tetrasulfonated Co(II) phthalocyanine, and the reductant (Ti(III) citrate) in TCE-contaminated sand-packed columns. Laboratory evaluation of Ti(III) citrate and CoPTS included both column and batch experiments. There were three series of initial column experiments to establish operational conditions, four series of batch experiments to set chemical conditions and the final column experiment that observed successful reductive dehalogenation of DNAPL in a TCE-contaminated sand-packed column within 10-17 PV of remedial solution injected.

description: Trafik- og miljøpuljen 1992-95 havde til formål at støtte udarbejdelsen og gennemførelsen af lokale handlingsplaner i kommunerne. Målsætningen var at reducere den trafikskabte miljøforurening i større bykommuner. Dette mål skulle opnåes gennem en tostrenget strategi, der dels bestod af en påvirkning af indholdet i de lokale handlingsplaner gennem en centralt formuleret vejledning, og dels var der knyttet økonomiske incitamenter til puljen, som kunne støtte gennemførelsen af konkrete foranstaltninger. Gennem denne strategi lykkedes det Miljøministeriet at skabe strategiske alliancer i kommunerne. Det gæler politikere og interessenter i almindelighed og de tekniske forvaltninger i særdeleshed. resultaterne var, at det i nogle kommuner lykkedes at anbringe de trafikskabte miljøproblemer på den kommunal- og miljøpolitiske dagsorden. Afslutningsvist stilles dog fokus på strategiens begrænsninger, idet der er en grænse for, hvor mange ressourcer kommunerne kan og vil afsætte til matche statslige initiativer.

description: Udvikling og drift af miljøtilsyn for HT-busser. Siden 1995 har der i HT's kontrakter indgået en klausul om, at busserne i hele kontraktperioden skal leve op til den pågældendes EURO-emissionsnorm. Der har i midlertid ikke eksisteret en brugbar målemetode, hvorfor hverken entreprenører eller HT har kunnet sikre dette. Målet med miljøtilsyn er, at HT i samarbejde med entreprenørerne kan sikre, at HT-busser kører emissionsmæssigt som aftalt i kontrakten, og dermed tæt på det optimale for den pågældende motor. I dette paper præsenteres udviklingen af en brugbar, hurtig og billig målemetode til bestemmelse af, om emissionerne fra en bus er acceptable eller for høje. Derpå beskrives erfaringerne fra det første års miljøtilsyn, samt hvordan busser målrettet kan forbedres mht. emissioner, herunder hvilke parametre der er afgørende for, hvor meget en bus i drift forurener i forhold til en tilsvarende ny bus.

description: We have seen recent advances in the fields of Machine Learning (ML), Deep Learning (DL), and Artificial intelligence (AI) that the models are becoming increasingly complex and large in terms of architecture and parameter size. These complex ML/DL models have beaten the state of the art in most fields of computer science like computer vision, NLP, tabular data prediction and time series forecasting, etc.  With the increase in models’ performance, model explainability and interpretability has become essential to explain/justify model outcome, especially for business use cases. There has been significant improvement in the domain of model explainability for Computer Vision and Natural Language Processing (NLP) tasks with fundamental research for both black-box and white-box techniques. In this paper, we proposed novel time series explainability techniques SPASE for black-box time series model forecasting and anomaly detection problems.

Motorring 3 er meget stærkt trafikeret, og i myldretiderne er der store køproblemer. En udvidelse af vejen vil forøge kapaciteten og dermed reducere køproblemerne. Men undervejs vil der i anlægsfasen blive nødvendigt med hastighedsbegrænsning, reduktion af sporbredde og i værste fald reduktion af antal kørespor. Det medfører en reduceret kapacitet, og trafikafviklingen bliver vanskelig. Omfaget af problemet ønskes forhåndsvurderet, som hjælp til planlægningen af en trafikafvikling i anlægsfasen med så små trafikantgener som muligt. En reduceret kapacitet på Motorring 3 i anlægsfasen vil medføre overflytning af biler til parallelle veje samt forøge trængslen på M3 og veje med overflyttet trafik. Almindelige planlægningsorienterede trafikmodeller kan ikke tilstrækkeligt præcist belyse trafikafviklingen under køsituationer, hvilket har nødvendiggjort anvendelse af en utraditionel fremgangsmåde. Formålet med indlægget er at præsente- re denne og beregningerne af fremkommeligheden i anlægsfasen.

Strategies for specification search as a cause of bias and inaccuracy of parameter estimates
Creators: name: Brundell-Freij, Karin
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2002

description: As we all know, model predictions and estimation results are erroneous. What we do not know is the size of those errors (had we done so, we would have compensated for them). Never the less, professionalism requires that we couple the model results we use, with some kind of measure of their estimated quality. Accuracy thus is a key issue of modelling – not only to obtain, but to properly describe. The typical tool we would use for description of model accuracy is standard errors of obtained parameter estimates. However, standard errors are only designed to illustrate a smaller part of those model errors that may arise from the complex process of developing a transport model. This paper discusses and investigates some such limitations in relation to the errors that may arise from specification search . Initial analyses, based on a combination of a real data set and simulation tools, will show that there may be considerable inaccuracy and bias caused by systematic factors that are outside the scope of standard error. Despite the fact that the concrete example, and implicitly much of the discussion, relates to models for discrete choice applied to transport demand, the general conclusions would apply also to a vast range of other types of modelling.

description: I en række sammenhænge er fordele og ulemper ved Stated Preference (SP) og Revealed Prefe- rence (RP) interviewteknikker blevet diskuteret (se f.eks. Denstadli & Strand, 2001). Fordelen ved SP er – ud over at kunne klarlægge fremtidige alternativer, der ikke eksisterer i dag – bl.a. at respondenters præferencer hvad angår korrelerede variabler lettere kan estimeres. Dette skyldes, at man i SP-eksperimenter styrer de spørgsmål, der stilles respondenten, og derfor systematisk kan variere forholdet mellem de forskellige variabler for de alternativer, respondenten vælger imellem. Er en rute eksempelvis både hurtigst og kortest kan en bilists præferencer for tid versus længde derimod ikke klarlægges ud fra RP-data. Således vil kun nogle af observationerne i et RP-datasæt kunne estimere præferencer. Derudover er det kun muligt at få flere observationer per person i SP-eksperimenter, end i de fleste RP-data. Derimod rummer SP selvsagt det problem, at respondenterne ikke nødvendigvis agerer i virkeligheden, som de påstår under interviewet. Omfanget af dette problem samt SP-teknikkens følsomhed over for forskellige variabeldefinitioner er sjældent klarlagt.

The Use of Multilinear Regression Models in Patterned Waterfloods: Physical Meaning of the Regression Coefficients
Creators: name: Gentil, Pablo Hugo
Publisher: name: The University of Texas at Austin
Year: 2005

Reservoir

description: One of the reservoirs engineer's mission is to predict the behavior of hydrocarbon producing assets. Once this ability is developed he/she will try to manage tbe ''today" to maximize the future economic return of the asset. However, the techniques to predict future performance vary from an educated guess of an appropriate analogy to very complex numerical approximations. But what they all have in common is that they are analyzing performance in the past to say something about the future. Hence, most models rely on fitting or matching to historic data. Albertoni (2002) proposed yet another approach using well rate fluctuations in waterfloods to predict interwell connectivity. He expressed the total fluid production at a producer as a weighted linear combination of the injection rates at different injectors located in the same reservoir. The relationship between the weights and the formation geological characteristics were not clear. For example, injection wells with no hydraulic connection to a producer may still exhibit a significant or even a negative weight. This work explores the physical meaning of the weights and proposes a new way to interpret them. In addition, the original model has been expanded and is now able to incorporate flowing bottomhole pressure fluctuations. These insights are used to better understand the underlying assumptions of the model used by Albertoni (2002) and to construct a procedure for incorporating production data into geostatistical permeability distribution models. The new interpretation of the weights arises as an analogy between constrained regression and parallel flow from each injector to all the producers. The procedure shows that the weights can be interpreted as the ratio of inverse distance weighted average permeabilities of well pairs associated with each injector (transmissibilities). They can also be interpreted as individual injector-producer water allocation factors that would result if there were no other injectors. This has been confirmed with flow simulation. Finally, a new water allocation model is proposed that, in combination with a water-oil ratio power-law model, has been used to regress oil rates with encouraging results in synthetic and real datasets.
History Matching Using Probabilistic Approach in a Distributed Computing Environment

Subjects: Reservoir
Permeability

description: A novel methodology for delineating multiple reservoir domains for the purpose of history matching in a distributed computing environment has been proposed. A fully probabilistic approach to perturb permeability within the delineated zones is implemented. The combination of robust schemes for identifying reservoir zones and distributed computing significantly increases the accuracy and efficiency of the probabilistic approach. The information pertaining to the permeability variations in the reservoir that is contained in dynamic data is calibrated in terms of a deformation parameter rv. This information is merged with the prior geologic information in order to generate permeability models consistent with the observed dynamic data as well as the prior geology. The relationship between dynamic response data and reservoir attributes may vary in different regions of the reservoir due to spatial variations in reservoir attributes, well configuration, flow constraints etc. The probabilistic approach then has to account for multiple rv values in different regions of the reservoir. In order to delineate reservoir domains that can be characterized with different rn parameters, principal component analysis (PCA) of the Hessian matrix has been done. The Hessian matrix summarizes the sensitivity of the objective function at a given step of the history matching to model parameters. It also measures the interaction between the parameters affecting the objective function. The basic premise of PCA is to isolate the most sensitive and least correlated regions. The eigenvectors obtained during the PCA are suitably scaled and appropriate grid block volume cut-offs are defined such that the resultant domains are neither too large (which increases interactions between domains) nor too small (implying ineffective history matching). The delineation of domains requires calculation of the Hessian, which could be computationally costly and also restricts the current approach to some specific simulators. Therefore a robust technique to evaluate a covariance matrix, which is analogous to the 'Hessian matrix', from a set of equi-probable realizations has also been developed. This technique is easy to implement. It yields the domains, which could be intuitively justified. Since the domain delineation process yields zones that are least correlated with each other, each rn parameter can be optimized independently and simultaneously using individual nodes of a cluster of computers. Further, the least correlation criterion helps in retaining the simplicity of 1-D optimization during the history matching. Upon convergence, the perturbed regions are put together and the history match is verified. The proposed approach results in a set of independent tasks of equal magnitude and thus is particularly suited for distributed computing. The methodology has been successfully tested on various synthetic cases.

description: Godstransport i byer foretages af et stort antal virksomheder, der hver især har begrænsede muligheder for at udnytte transportapparatet effektivt. Ved en koncentration og koordinering af godstrafikken kan der principielt opnås store besparelser i godstrafikarbejdet og den deraf følgende miljøbelastning. I projektet opstilles modeller for koncentration af godstransporten, og modellernes konsekvenser vurderes. Modellerne omfatter bl.a. etablering af særlige citylogistik-selskaber, der arbejder målrettet for en effektiv, koncentreret bydistribution. Som et incitament til transportørerne foreslås en certificeringsordning, således at effektive transportører kan blive certificeret og dermed opnå visse fordele i forhold til andre transportører.

description: Fördraget är en sammanfattning av rapporten "Färder i framtiden - Transporter i ett bärkraftigt samhälle". Hur kan ett bärkraftigt transportsystem för Sverigese ut? Studien har angripit denna fråga genom att formulera en framtidsbild (med varianter) av transport i ett framtida samhälle som uppfyller krav som ställs av "sustainable development". Tidsperspektivet är 40 - 50 år, cirka år 2040. växhuseffekten har antagits innebära att koldioxidutsläppen från fossila bränslen, räknat per capita, måste reduceras med mellan 80 - 100%. Detta leder till att transportsektorns energibehov behöver minskas till hälften respektive en tredjedel. I alternativet där transportsektorn drivs med en tredjedel av dagens energianvändning antages enbart förnybara energislag användas. Ny transportteknik analyseras och den kan väsentligt reducera energianvändningen per personkilometer respektive godskilometer. Därför analyseras även drivkrafterna bakom transporternas utveckling. Ett strategiskt val identifieras: Mycket av dagens resande utgöres av strukturellt tvungna resor (till och från arbete, för inköp, service etc). Dessa kan rduceras avsevärt genom samhällsplaneringsåtgärder och användande av IT. Sker detta kan ett ökat utrymme för önskat resande skapas, dvs olika former av fritidsresande.

description: Konkurrencedygtige rejsetider og høj regularitet er meget afgørende for et velfungerende højklasset busnet. Samtidig er terminalers og Park & Ride pladsernes succes meget afhængig af, at den kollektive transport kører rettidigt og korresponderer. Særligt i Københavnsområdet er bussernes hastigheder lave og regulariteten for dårlig. Det hænger primært sammen med den stigende biltrafik på vejnettet, samtidig med at vejen flere steder benyttes tæt på eller over kapacitetsgrænsen. Dernæst hænger det sammen med trafiksaneringer, der desværre mange gange er kendetegnet ved at have en negativ effekt på bussernes rejsetider. Mange trafiksaneringer af lokale byområder har tit den konsekvens, at meget trafik flyttes ud på de større veje, hvor busserne kører. Man ” glemmer” ofte at tænke i busvenlige løsninger. HT har derfor igennem de seneste par år dels satset på at intensivere HT og nogle af de centrale vejmyndigheder samarbejde om at forbedre busfremkommeligheden og dels på at synliggøre trængselsproblemerne bl.a. ved hjælp af GIS. HT har i den forbindelse udviklet et GISprogram FREM2, som på baggrund af data indsamlet fra HT’s tællebusser visualiserer hvor hurtig busserne kører i hele HT-området.

Publisher: name: Wiley-VCH

description: Precipitate hardening is introduced as a mechanism to tune the reaction of ferroelectric materials to the application of an external electric field. For this purpose, a phase field model for polarization in ferroelectric material is presented in this paper. Different materials with and without precipitates are simulated and the respective hysteresis curves for charge and macroscopic strain are derived. The results show a reduction of the hysteresis curves if precipitates are present in the material, which confirms the experimental observation of recent material studies.

description: Measuring the number of papers which are published each year, publication productivity is the factor which shows the reputation of universities and countries. However, the effect of growing economy and using internet on the publication productivity in Asian countries has not been discovered yet. The present research is going to figure out the publication productivity among the elite universities in Asian countries and also ten top universities around the world in the last twenty years (from 1993 to 2012). Furthermore, the current research is aimed to study the relationship among publication, gross domestic product (GDP) and internet usage. It is worth to mention that the publication of the top Ten Malaysian Universities was regarded for the similar period of time. To get the exact numbers of documents like papers, conference articles, review papers and letters which are published by the universities in the last twenty years, the writer of the same paper used the Science Direct database. Moreover, the data for GDP and the number of internet usage was collected through the World Bank database (World Data Bank).To compare all kinds of publications,one-way ANOVA was used and to investigate the impact of economic growth and internet usage on publication productivity, multiple regression analysis was applied.The results showed that the rate of publication growth was 1.9, 20.9, and 65.5 % in top universities in the world, ASEAN countries and Malaysia, respectively.The results also showed that there was a positive and significant correlation between GDP and the number of internet users with the number of publications in ASEAN and Malaysian universities. Internet usage had much more influence in comparison with the GDP in predicting the number of publications among these groups except for top ten Malaysian universities from 2003 to 2012. In summary, publication trends in top ten Malaysian and ASEAN universities are promising. However, policy makers and science managers should spend much more percentage of their GDP on Internet facilities and research studies that their outputs lead to more rapid economic growth and internet usage.

description: LGBTQ+ Asian Americans experience unique psychological health concerns at the intersection of multiple forms of marginalization. White supremacist, cisheteronormative, and colonial ideals and their structural and interpersonal manifestations may encourage family rejection of LGBTQ+ identities within Asian American family units. Family shame, conflicts in allegiances, and internalized anti-LGBTQ+ stigma were hypothesized as mediators in the association between family rejection and psychological distress and disordered eating. The current study examined family rejection and its impacts on psychological distress and disordered eating in a sample of LGBTQ+ Asian American adults (N = 155; MAge = 24.26; 30.3% Gender Diverse) using a cross-sectional survey design and path analysis. There was a significant serial mediation such that family rejection was positively associated with conflicts in allegiances, which was positively associated with familial shame, which was positively associated with psychological distress (B = .12, p = .01). The same serial mediation was nonsignificant for disordered eating (B = .04, p = .26). Results indicate the importance of considering conflicts in allegiances, family shame, and the interpersonal dynamics of LGBTQ+ Asian Americans in understanding experiences of psychological distress and disordered eating. Implications are drawn for further research, clinical work, and broader efforts addressing the larger sociocultural environment that encourages familial rejection of LGBTQ+ identity.
