Unveiling stellar-mass black holes in globular clusters with dynamical models.
Creators: name: Peuten, Miklos
Publisher: name: University of Surrey
Year: 2020

description: The recent discovery of a gravitational wave produced by two merging stellar-mass black holes started a search for environments where two stellar mass black holes can become a binary and merge. One favourable environment could be globular clusters, but the evolution of black holes in them is still widely debated. In this thesis, I present a method, based on isotropic lowered isothermal multimass models with which stellar mass black hole populations in globular clusters can be dynamically inferred and the main properties of the cluster can be estimated. In the models, I am using an improved stellar evolution code from Balbinot and Gieles (2018) to which I added black hole evolution. Before applying the multimass models to data, I made a detailed comparison between the properties of multimass models and collisional N-body simulations. I find that all dynamical stages are well described by the models and that a stellar mass black hole population reduces mass segregation. For the Milky Way globular cluster NGC 6101, I run three N-body simulations to show that the observed lack of observable mass segregation could be explained by a stellar mass black hole population. To differentiate this explanation from others, I create different multimass models and find that measuring the cluster's velocity dispersion could help to prove the black hole population. In the final chapter I follow-up on this prediction, and present new line-of-sight velocities of NGC 6101's velocities with the ESO MUSE instrument, I find, applying my method, that the cluster has 86+30-23 black holes, which could explain its currently observed lack of mass segregation. This thesis is concluded by a discussion on how to improve dynamical detections of BH populations with future observations and models.

Experimental and numerical investigation of the crashworthiness performance of sandwich structures
Creators: name: Carranza Guisado, Ignacio
Publisher: name: University of Surrey
Year: 2020

description: There has been a growing interest in the last decade for the use of composite materials in the automotive industry, due to their low weight and high energy absorption capabilities. Predicting the response under impact conditions of these lightweight materials is crucial for both design and reduction of manufacturing and testing during the development of new vehicles. However, the complexity of composites makes it difficult to predict their behaviour using Finite Element Analysis (FEA). Hence, this research looks into the development of a reliable Finite Element methodology to simulate lightweight automotive crash structures, combining composite materials with polymeric foams in a sandwich panel. To achieve that goal, firstly a calibration process of a constitutive model for crushable foams was developed, including the proposed experimental tests to characterise the polymer. The approach was then validated by correlating a mixed-mode indentation tests with its corresponding Finite Element model and results from Digital Image Correlation (DIC). Secondly, different configurations of the crash structure were tested under mixed-mode loading conditions at quasi-static rates, based on the side-pole impact test. These experiments provided a better understanding with regard to the performance of each configuration. Furthermore, they were used to develop a robust FE methodology to accurately predict their behaviour, including good correlations in terms of load-displacement and failure mechanisms. Finally, the methodology was employed to design an impact test on a similar crash structure. The tests were conducted, and the outcomes were used to improve the Finite Element models, showing good agreement in terms of loads and energy absorption capability. It was found that the structures that were tested did not experience composite crushing, highlighting the need of further optimisation of the sandwich structure. Therefore, having validated the numerical methodology, FEA can now be used to assess the influence of different design approaches to improve the performance of this type of crash structures, prior to the manufacturing and testing of new full-size components.

Relationships of firms in the textile industry in Pakistan: an exploration of Talukaat.
Creators: name: Qureshi, Naveed A.
Publisher: name: University of Surrey
Year: 2020

description: Studies on Asian business clans have highlighted the importance of networks in business operations. However, there has been less attention on social ties as an instrument to influence and maintain business ties. Despite being present and contributing substantially to the Pakistan economy, little is known about Talukaat, a form of business clan. Indeed, its role in business performance notwithstanding, there is a paucity of knowledge regarding its nature and formation. In this regard, this study seeks to contribute to knowledge about Asian business clans particularly by exploring Talukaat in the context of the textile industry in Pakistan. To examine Talukaat, this thesis sought to answer three exploratory research questions which were drawn from the literature (i) to develop an understanding of what Talukaats are (ii) how they operate and (iii) how they compare to other Asian business clans. The thesis utilised Social Network Theory as a theoretical lens to examine Talukaat. To answer the research questions and offer detailed perspectives on Talukaat, an inductive approach was adopted. This approach, together with the epistemological stance of interpretivism involved the use of semi-structured interviews, observation guides, and a snowball sampling technique. This research methodology was used to explore the in-depth knowledge of business managers operating in Pakistan’s textiles industry. The findings suggest that business ties are underpinned by social ties, and the two are inseparable. It also came to light that, networks formed in businesses operate through shared social values, preventing opportunism and maintaining solidarity in them. From the findings, a definition of Talukaat was drawn to highlight the main features of the network: a closed but informal network that relies on direct social ties based on a number of constructs including kinship, community, friendship, trust, collectivism, reciprocity and facilitative professionalism which is influenced by shared social values. Moreover, the findings provide a better understanding of the role Talukaat plays in the textile industry in Pakistan. A comparison of Talukaat network to three other Asian clans: Japanese Keiretsu, Chinese Guanxi and Arabic Wasta revealed that, all three are closed networks implying there is limited access of ‘outsiders’ to the network. Compared to Chinese Guanxi, Talukaat showed extensive influence over business decisions whereas, Japanese Keiretsu and Arabic Wasta do not. The thesis makes important contributions to knowledge by exploring Talukaat, and in so doing adding an additional facet to the examination of business clan networks, and more importantly from an Asian perspective. The thesis has also revealed that managerial decision making in the Pakistani textile industry is influenced by Talukaat and this has wider implications on business networks and operations.
Compound interval cycles and derived aggregate arrays in Anton Webern's atonal miniatuary.
Creators: name: leGassick, Damian A.
Publisher: name: University of Surrey
Year: 2020

description: A number of individual movements composed by Webern between 1909 and 1914 can be shown to be partly or wholly derived from chromatic aggregate arrays — linear, ordered constructs. These aggregate arrays are themselves derived from one of two compound interval cycles: c.c. 1:3, which ascends by semitones and minor thirds (the hexatonic scale), and c.c. 6:7, which ascends by tritones and perfect fifths. Webern's engagement with these aggregate arrays is described in terms of 'background' (the array as pre-compositional resource), 'deployment' (the selection of conjunct spans on the arrays), 'traversal' (deployment of contiguous or overlapping spans expressed in terms of direction) and 'articulation' (the transformation of the deployed spans into actual music). The presence of these arrays explains much of the 'data' posited by extant analyses of these movements; especially those that belong to the traditions of pitch-class set analysis, chromatic aggregation, or chromatic wedge formation. Webern's use of c.c. 1:3 and c.c. 6:7 is traced back as far as the 1905 String Quartet, where they operate as collections rather than arrays, and in a tonal context. Aggregate arrays in Op. 5 (1909) are found alongside hexatonic music akin to the Fortspinnung found in the 1905 Quartet (they are also found alongside decisively non array-based music). By 1911, Webern is deriving entire movements from these aggregate arrays (Op. 9/II, Op. 9/IV and Op. 10/IV). The end-point of this dissertation is a pair of movements from 1913–1914 (Op. 9/VI and Op. 11/II) where c.c. 6:7 and c.c. 1:3 aggregate arrays respectively interact with non-patterned arrays that are themselves secondary derivations of composed music. These non-patterned arrays, which are traversed in order, just like their patterned counterparts, are 'series' in all but name.
Vaccine development and genomics of the soil-transmitted helminth Ascaris
Creators: name: Evangelista, Francisco Miguel Dias
Publisher: name: University of Surrey
Year: 2024

description: The zoonotic parasite Ascaris is estimated to infect over 700 million people worldwide while concomitantly remaining one of the most common helminth infections in pigs. The use of anthelmintic drugs remains the most frequent control method in both human and pigs. There has been an increased interest regarding alternative control methods due to the possibility of the development of resistance to anthelmintic drugs.

description:

description: This study used a reverse vaccinology approach to identify potential vaccination targets against ascariasis present in Ascaris proteomes. Due to the zoonotic nature of the parasite, this was done using both A. lumbricoides and A. suum proteomes. Four proteins, a cadherin, a Piezo channel, and two calcium channels (T-type and L-type), were identified as putative vaccination targets and predicted to bind to both B-cells and T-cells.

description:

description: A multi-epitope vaccine polypeptide was designed using an in silico methodology. This polypeptide was designed with epitopes from the four proteins identified through the reverse vaccinology approach alongside epitopes from the established targets As14, As16 and As37. Immune simulations predicted a beneficial immune response with the potential to control Ascaris infections.

description:

description: Based on whole-genome sequence data, the vaccine targets integrated in the multi-epitope vaccine had a low variation rate in Ascaris samples from the Philippines. Nevertheless, some targets had mutations that require further research due to potential protein truncation, making them unviable as vaccine targets in this population. Furthermore, mitochondrial genome phylogenetic analysis highlighted the similarities between Ascaris strains from humans and pigs from geographically distinct parts of the world.

description:

description: The research presented in this work has identified additional potential Ascaris antigens for vaccine development and highlights the benefits of incorporating these antigen epitopes into a single polypeptide to enhance vaccine efficacy. This will open further research venues and reinforces reverse vaccinology as a useful tool for vaccine development in Ascaris.

description: Background: Gastric pull up remains a popular reconstructive option for pharyngoesophagectomy defects extending to thoracic inlet. Gastric necrosis is a dreaded complication of gastric pull up reconstruction and few studies report on management of this complication. MEDLINE, EMBASE, and Web of Science™ databases were searched for publications in the last 25 years on gastric pull up reconstruction following pharyngoesophagectomy. The rates of complications related to gastropharyngeal anastomosis were extracted, and methods of managing gastric necrosis were noted. Forty seven case series were identified reporting on the use of gastric pull up for reconstruction of pharyngoesophageal defects. Mortality rate varied from 0 to 33 % with a weighted average of 8.6 %. In 39 % of patients, mortality was either caused or directly related to failure of the gastropharyngeal anastomosis. The reported rate of gastric necrosis ranged from 0 to 24 % resulting in a 28 % mortality. Options for managing gastric necrosis included: temporary cervical diversion, free jejunum flap, colonic interposition, tubed radial forearm flap, deltopectoralis and pectoralis myocutaneous flaps. Case presentation: We present the first case of an anterolateral thigh flap rescue of gastric necrosis after gastric pull up reconstruction. The case report is followed by a review of literature on management of gastric pull up failures. Conclusion: Based on the extracted information, we propose an algorithm for managing gastric pull up failure following pharyngoesophageal reconstruction.

title: The Politics and Poetics of Latin American Magical Realism
Creators: name: Bennett, Caroline Jane
Publisher: name: Goldsmiths, University of London
Year: 1999

description: The phenomenon of the magical realist genre in twentieth century Latin American fiction is the subject of this thesis. Part I, comprising three chapters, considers the theoretical aspects of magical realism. Chapter One traces the genealogy of the critical writing on magical realism, and identifies a number of problems. In Chapter Two, the European and Latin American textual ancestry is established. Chapter Three, dealing with the politics and poetics of magical realism, first lays bare the attributes of both classic realism and surrealism, demonstrating magical realism's dependence on realist methodology in its depiction of 'magical' events, and clarifies its difference from other realisms. Also, in this chapter, a specific postcolonial structure of feeling is identified with magical realist fiction; the consciousness of South and Central American writers has assimilated the culture of both the former coloniser and the colonised, and this co-existence of two contradictory cultures produces the structure of feeling that lies behind magical realism. In part, literature is viewed, effectively, as the practice of the collective socio-political unconscious, and magical realism is conceived as a mode of resistance to the colonially imposed construction of identity. It can also be one of the channels through which non­hegemonic groups appropriate cultural capital. The remainder of this chapter deals with further postmodern characteristics and issues concerning postcolonialism. Part II contains three chapters which are devoted to close textual analysis of the following narratives: The Kingdom of This World by Alejo Carpentier; One Hundred Years of Solitude and 'Innocent Erendira' by Gabriel Garcia Marquez; and The House of the Spirits by Isabel Allende.
Optimization of Timetable Supplement from a Passenger Based Socio-Economic Point of View
Creators: name: Thorhauge, Mikkel
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2010

description: This article discusses how to optimize the timetable supplement in timetables. The focus of this article will be on railways, but the principle will in theory apply to all transportation modes within the area of public transportation. When constructing timetables it is important to plan the right amount of timetable supplement. Too little timetable supplement will result in many delays, while too high timetable supplement will result in a (too) high planned travel time which will affect every departure whether or not the train is delayed. At present timetable supplement is chosen based on experience or estimates. Through an optimization process it is possible to find the optimal timetable supplement. A way to do so is by using the passenger delay model in a socio-economic analysis as done by (Thorhauge & Piester, 2010). In this process the train delays (or a simulation of the train delays) are needed. The overall process is (if the train delays are not already known): Simulation of train delays → modeling passenger delays → estimation of the socio-economic effects A case study of an upgrade of Sydbanen between Ringsted and Rødby has been conducted using the passenger delay model and the methods are described in this article. The case study has shown that the optimum timetable supplement is between 6-9 % depending on the scenario. By optimizing the timetable supplement it is possible to achieve a surplus of 250-500 mio. DKK during the evaluation period compared to the proposed timetable by the Danish Transport Authority (Trafikstyrelsen, 2008). Note however that none of the investigated scenarios are socio-economic viable even though the timetable and timetable supplement is optimized. Note that this paper is regarded as a sequel to the article “The usability of passenger delay models in socio-economic analysis” (Thorhauge, 2010). This article is based on the results of (Thorhauge & Piester, 2010).

Muligheden for elektrificering af jernbanenettet i Nordjylland
Creators: name: Jensen, Tommy Odderskjær
name: Nautrup, Lars
Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2010

description: Efter det brede forlig En Grøn Transportpolitik blev vedtaget i januar 2009, har der været landspolitiske udmeldinger om, at det stadig er et langsigtet nationalt mål om at elektrificere hovedjernbanenettet i Danmark. Tidshorisonten rækker efter al sandsynlighed ud over signalprogrammets gennemførelse, og måske helt frem til omkring 2035 førend elektrificeringen i den omform der kendes i dag kan afsluttes. Nærmere afklaring vil ske når ”Strategisk analyse af elektrificering af banenettet” fremlægges i 2011. Atkins Danmark har for Region Nordjylland undersøgt mulighederne for at fremskynde elektrificeringen i regionen, som led i en opdatering af regionaltrafikken i Vendsyssel og Aalborg Nærbane. Undersøgelsen indikerer, at elektrificering af delafsnit Hobro-Hjørring kan gennemføres langt tidligere, omkring 2018, men med en reduceret anlægsmængde (f.eks. færre opstillingsspor, færre forsyningsstationer/banetransformere). Ved at kæde elektrificeringen sammen med opgraderingen af strækningen Hobro-Aalborg til væsentligt højere hastigheder som del af timeplanen, etablering af nyt signalsystem, samt et udtalte behov for reinvestering af tog på Aalborg Nærbane og i Vendsyssel, vil der være der oplagte muligheder for synergi mellem tre vidt forskellige og store investeringer. Omkostningerne til elektrificering af Hobro-Aalborg-Lindholm skønnes til ca. 650 mio. kr. (2008- prisniveau) og for yderligere 850 mio. kr. kan Lindholm-Hjørring-Frederikshavn og Nordjyske Jernbaner også omfattes af elektrificeringen. Når det nordjyske køreledningsnet sammenbygges med et landsdækkende køreledningsnet, vil det være nødvendigt at supplere investeringen op til 120 mio. kr.

Ny anlægsbudgettering på banen

Publisher: name: Proceedings from the Annual Transport Conference at Aalborg University
Year: 2010

description: I nærværende artikel diskuteres implementeringen af Ny Anlægsbudgettering på baneområdet. Diskussionen er gennemført på ere niveauer, idet der indledningsvis gives en overordnet beskrivelse af baggrunden og det egentlige formål med Ny Anlægsbudgettering og efterfølgende redegøres i detalje for de værktøjer og den struktur, der er nødvendig, for at Ny Anlægsbudgettering kan implementeres. Ny Anlægsbudgettering er baseret på de to grundlæggende principper, at der anvendes erfaringsbaseret budgettering, og at der etableres sporbarhed i baneprojekter. Princippet om anvendelse af erfaringsbaseret data er i sig selv simpelt, men det viser sig at være ganske kompliceret at etablere det grundlag, som muliggør, at erfaringsbaseret data kan anvendes i praksis. Dette er en væsentlig observation, som danner grundlaget for det meste af artiklens indhold. Det beskrives, hvorfor den praktiske anvendelse er udfordrende, og i naturlig forlængelse heraf beskrives de tre elementer, som sikrer, at udfordringerne kan løses. Løsningen forudsætter, at der etableres en hensigtsmæssig data- og projektstruktur, at der etableres et hensigtsmæssigt aggregeringsniveau til brug ved budgettering, samt at der opbygges en prisdatabase, som skal undergå kontinuerlig vedligeholdelse. Disse tre aspekter er diskuteret individuelt, og den detaljerede redegørelse har til hensigt at give læseren en forståelse af kompleksiteten i de enkelte problemstillinger såvel som et godt overblik over, hvorledes disse er løst. Artiklen fokuserer på en diskussion af de nødvendige forudsætninger og forklarer, hvordan disse opstår som aedte behov af de overordnede krav i Ny Anlægsbudgettering. Endvidere redegøres for, hvorledes forudsætningerne imødegås ved anvendelse af værktøjer og opbygning af en hensigtsmæssig datastruktur. Principperne i Ny Anlægsbudgettering er ikke specikke for baneområdet og kan således finde mere generel anvendelse indenfor økonomistyring på andre fagområder. Diskussioner og konklusioner fra artiklen kan derfor umiddelbart generaliseres til andre fagområder, selvom artiklen tager sit udgangspunkt i diskussionen af implementering af Ny Anlægsbudgettering på baneområdet.

Development and Application of CFD for Aeroelastic Modelling
Creators: name: KUMAR, RAMESH
Publisher: name: University of Surrey
Year: 2020

description: This thesis describes the development and application of a methodology for modelling fluid-structure interaction (FSI). The method uses a mesh deformation algorithm integrated within an industrial computational fluid dynamics (CFD) code solving Reynolds averaged Navier-Stokes (RANS) equations in the arbitrary LagrangianEulerian (ALE) formulation. Three classes of problems have been investigated: dynamic stall, stall flutter and leaf seal dynamics for turbomachinery applications. In the first one, the flow over an aerofoil pitching from 5◦ to 25◦ at high Reynolds numbers has been studied for different reduced frequencies. CFD results have been found to be in reasonably good agreement with both the experimental and computational results available from the literature. In the subsequent part of the thesis, the CFD code has been coupled with a dynamic structural model of the aerofoil, and stall flutter simulations have been conducted to study the effects of the initial condition on the amplitude of limit cycle oscillation (LCO) in the stable region. The third application study focuses on the aeroelastic instability of a leaf seal in the secondary air system of gas turbine. Leaf seals can be deployed in gas and steam turbine secondary air systems to reduce parasitic leakages close to rotating shafts. They consist of multiple flexible elements which have to withstand substantial pressure loads during operation. Leaf seal issues are anecdotally associated with the risk of vibration due to the high energy contained within the fluid. This may lead to transient forcing imposed on the flexible elements. Modal analysis of a single leaf has shown that the natural frequency is significantly affected by leaf-rotor contact, while pressure loading is less important. A blow-down neutral clearance seal design was identified for further analysis, using one-way FSI. Transient leaf deflections for the first-flap and third twist modes were imposed on the leaf during unsteady CFD simulations. Unsteady flow structures in the vicinity of the leaf pack, including trailing edge vortex shedding, were identified. Fourier spectral analysis and worksum calculations showed that first mode is stable, whereas a possible flutter instability was observed for the third mode due to interaction with vortex shedding.
description: Influence coefficient method was developed which evaluates the modal forces on the vibrating leaves including the effects of neighbouring leaves. Further, this was implemented in the modal model to study the circumferential travelling waves.
description: Prediction of travelling waves with first mode are found encouraging and this methodology can be used to assess higher modes.

Gender in United Nations peacebuilding: A case study of Timor-Leste
Creators: name: Smith, Sarah
Publisher: name: Swinburne
Year: 2024

description: Using successive United Nations peacebuilding missions in Timor-Leste as her focus, Dr Smith analysed how and why gender has come to be part of peacebuilding practice, and how gender policies are implemented on the ground in post-conflict settings. This examination demonstrated limitations in the way women's role in peacebuilding has been conceptualised and practiced by United Nations peace operations. The insights gathered in the Timor-Leste case study provide significant and timely lessons for how gender is understood and practiced in international peace operations, and what this means for women's empowerment and women's security in post-conflict settings.
Højklassede bussystemer kan bidrage til den ”positive spiral” indenfor den kollektive trafik

description: Kun hver femte københavner bruger udelukkende kollektiv transport til og fra arbejde. Københavns kollektive trafik ligger dermed i bunden sammenlignet med andre europæiske byer. Skal den kollektive trafik blive en succes skal der tages ved lære af de udenlandske erfaringer: • begrebet "skinneeffekt" skal gentænkes, som i Frankrig mm., så den fremstår som "systemeffekt" • der skal satses på det kunderne efterspørger, nemlig høj rejsehastighed, høj pålidelighed og høj frekvens • introducere flere højklassede transportløsninger • fjerne sig fra rygmarvsløsningen = letbaner, men se på mere rentable løsninger som f.eks. højklassede busser (som i de franske vejregler) • rykke på konkurrenceforholdet mellem kollektiv trafik og biltrafik (som det gøres i Frankrig, Tyskland, Norge mm.)

description: The Internet of Things is not just a theoretical topic anymore, but it has become a reality that affects everyday life in many aspects. Users and devices can now be connected to the Internet whenever, wherever and interact with each other in revolutionary ways. Mobile Crowdsensing (MCS) is a collaborative demonstration of this interaction. However, MCS introduced a series of challenges surrounding the areas of power management, privacy preservation, and data quality. These may result in compromised user experience, limited user acceptance, and minimise the potential this area has to offer. This study addresses the discussed problems by examining the impact Internet of Things (IoT) communication protocols have on modern mobile crowdsensing systems. To do so, an end-to-end crowdsensing system is designed to evaluate the most popular IoT protocols. Simulation and off-the- shelf-device-based experiment runs provided an insight on the performance of the said protocols. Based on the findings, a new sensing approach is introduced aiming to improve system’s robustness and minimise energy requirements. Finally, a user-preference efficient crowdsensing algorithm that determines the most efficient communication protocol based on user input and experiment parameters is proposed.

description: Background: Information on above-ground biomass (AGB) is important for managing forest resource use at local levels, land management planning at regional levels, and carbon emissions reporting at national and international levels. In many tropical developing countries, this information may be unreliable or at a scale too coarse for use at local levels. There is a vital need to provide estimates of AGB with quantifiable uncertainty that can facilitate land use management and policy development improvements. Model-based methods provide an efficient framework to estimate AGB. Methods Using National Forest Inventory (NFI) data for a ~1,000,000 ha study area in the miombo ecoregion, Zambia, we estimated AGB using predicted canopy cover, environmental data, disturbance data, and Landsat 8 OLI satellite imagery. We assessed different combinations of these datasets using three models, a semiparametric generalized additive model (GAM) and two nonlinear models (sigmoidal and exponential), employing a genetic algorithm for variable selection that minimized root mean square prediction error (RMSPE), calculated through cross-validation. We compared model fit statistics to a null model as a baseline estimation method. Using bootstrap resampling methods, we calculated 95 % confidence intervals for each model and compared results to a simple estimate of mean AGB from the NFI ground plot data. Results Canopy cover, soil moisture, and vegetation indices were consistently selected as predictor variables. The sigmoidal model and the GAM performed similarly; for both models the RMSPE was ~36.8 tonnes per hectare (i.e., 57 % of the mean). However, the sigmoidal model was approximately 30 % more efficient than the GAM, assessed using bootstrapped variance estimates relative to a null model. After selecting the sigmoidal model, we estimated total AGB for the study area at 64,526,209 tonnes (+/− 477,730), with a confidence interval 20 times more precise than a simple design-based estimate. Conclusions Our findings demonstrate that NFI data may be combined with freely available satellite imagery and soils data to estimate total AGB with quantifiable uncertainty, while also providing spatially explicit AGB maps useful for management, planning, and reporting purposes.

Modelling and simulations of energy storage devices

description: Energy storage is a field which governs almost all aspects of daily life. Batteries and capacitors are utilised in devices at every scale, from mobile phones all the way up to the national grid. Efficient energy storage requires extensive research into chemistries and configurations, utilising novel materials to assemble devices. These often have a significant effect on features including the energy and power density of a cell. One such property is the pore structure of an electrode. Electrochemical Double-Layer Capacitors, also known as supercapacitors, utilise meso/microporous electrodes with a wide distribution of pore sizes. Larger pores typically facilitate ion diffusion and a high device power density, yet smaller micropores provide a large specific surface area for the electric double layer which facilitates a high device energy density. Recent advancements in post-lithium ion battery technology (such as lithium-sulphur and lithium air batteries) utilise these micropore surface areas for redox reactions. Developing accurate models of energy storage devices allows for the simulation of the processes within the cells without the need for expensive and time-consuming experimental testing. Many models have been developed in the past, however sweeping assumptions are often made with respect to the pore structure. These generally assume a uniform pore size and structure, and do not take into account the effects of different pore sizes present in a true electrode material. Pore network models are able to do this, but require complex or expensive pieces of software and a long simulation time. In this project, a novel continuum model of mass and charge transport has been developed catering for the many pore sizes in an electrode. This model allowed for the simple implementation of a pore size distribution into the simulation of the processes in several supercapacitor configurations, a lithium-sulphur battery, and two lithium-oxygen battery configurations. This novel approach involved characterising an electrode material through analysis of the pore structure and pore size distribution. A novel mathematical transient volume averaged model was developed to solve for the mass transport of species within pores of different sizes. The use of this model in each case demonstrated good agreement with experimental data and allowed for analysis of the effects of different pore structures on the activity of cells. It was found that larger pores (in the macropore region) facilitate mass transport of species, and smaller pores (in the micropore region) have a reduced rate of mass transport and a higher rate of reaction (in batteries) and stern layer formation (in supercapacitors). This novel model demonstrated the importance of modelling ion transport through multiple pore sizes of an electrode material. This model also addresses the need for more complex energy storage device simulation in a reasonable solving time without the need for expensive pieces of software.
Mobilitet og personbefordring i landdistrikter

description: Befordring i landdistrikterne er et centralt emne i disse år, hvor den kollektive transport omorganiseres og bliver efterspørgselsstyret, befolkningstallet er vigende og behovet for befordring er større end nogensinde før. Samtidigt åbner moderne kommunikationsteknologi op for nye måder at organisere befordringen på. Derfor blev befordringsbehovet undersøgt i Favrskov Kommunes landdistrikter (det åbne land og landsbysamfund med op til 1.000 indbyggere). Dataindsamlingen blev foretaget ved hjælp af en spørgeskemaundersøgelse, fokusgruppeinterviews og en ekspertkonference. Hovedresultaterne fra undersøgelsen er, at landdistriktsbeboerne i det store hele har de samme problemer og daglige udfordringer, som flere tidligere undersøgelser fra Danmark også viser: nemlig at den kollektive transport kun opfattes som et relevant og brugbart personbefordringsmiddel af et fåtal, og det vigtigste transportmiddel er personbilen, samt at befordringsbehovet ikke opfyldes tilstrækkeligt. Endvidere vi- ser undersøgelsen, at langt hovedparten af undersøgelsens respondenter anvender moderne kommunikationsmidler såsom mobiltelefon og Internet, og at manglende forståelse af disse ikke er en barriere mod indførelse af mere intelligente løsninger på personbefordringen på landet i fremtiden.
