description: In this work, the mass of the neutral pion is investigated in the presence of background magnetic fields in the framework of the Nambu--Jona-Lasinio model. Taking into account the anisotropic four-fermion interactions, a tensor current arises in the magnetized QCD system, which forms an anomalous magnetic moment (AMM) coupling in the Dirac equation for the quarks. By solving the gap equations, we find that the sign of the dynamically generated AMM is opposite to the sign of the quark's charge and its magnitude is definitely smaller than the constituent mass. We construct two generalized Nambu-Goldstone pions, which emerge as combinations of the quantum fluctuations around the conventional scalar and the emergent tensor chiral condensates. We analytically demonstrate that the Goldstone nature has been spoiled by the dimensional reduction in the two-particle state and the corresponding decreasing mass of the lighter generalized pionic mode is a remnant of the infrared dynamics.

title: Models of directed technical change
Creators: name: Grames, Johanna
Publisher: name: TU Wien
Year: 2013

description: In macroeconomic growth models technology is often exogenous or endogenously described with simple dynamics. The diploma thesis analyses the dynamics, but also the direction and the bias of technical change. The basic framework introduced by Acemoglu, (2002) is a two-sector model. Each sector uses different technologies. If the economy is switching from the technology in one sector to the other, we face directed technical change. The reasons and the policies to direct technical change are discussed for the basic model of Acemoglu, (2002). Further extensions that also include the dynamics of environment and population are introduced afterwards. The main focus is the quality of environment. What happens, if one sector needs natural resources to produce its goods? Which policies can be set to attract researchers to invest in sustainable technologies? The paper of Acemoglu, Aghion, Burstyn and Hemous, (2012) describes scenarios with renewable and exhoustible natural ressources. This paper also introduces different aspects of technical change and environment: Is economic growth still possible, if the production of the consumption good always affects the environment negatively, even if there exists a second production sector that decreases pollution of the first sector and increases the regeneration rate of the environment? A more complex model of directed technical change is based on the work of Schaefer, (2012). Additional to the factor environment it includes population dynamics and works with two different types of households - skilled and unskilled. As a result, the educational choice of parents for their offspring plays a crucial role to direct technical change. The diploma thesis describes and compares these four different models of directed technical change.

description: Given a stationary continuous-time process $f(t)$, the Hilbert-Schmidt operator $A_τ$ can be defined for every finite $τ$\cite{Vautard1989SingularSA}. Let $λ_{τ,i}$ be the eigenvalues of $A_τ$ with descending order. In this article, a Hilbert space $\mathcal{H}_f$ and the (time-shift) continuous one-parameter semigroup of isometries $\mathcal{K}^s$ are defined. Let $\{v_i, i\in\mathbb{N}\}$ be the eigenvectors of $\mathcal{K}^s$ for all $s\geq 0$. Let $f = \displaystyle\sum_{i=1}^{\infty}a_iv_i + f^{\perp}$ be the orthogonal decomposition with descending $|a_i|$. We prove that $\displaystyle\lim_{τ\to\infty}λ_{τ,i} = |a_i|^2$. The continuous one-parameter semigroup $\{\mathcal{K}^s: s\geq 0\}$ is equivalent, almost surely, to the classical Koopman one-parameter semigroup defined on $L^2(X,ν)$, if the dynamical system is ergodic and has invariant measure $ν$ on the phase space $X$.

description: The well known algorithm of Volker Strassen for matrix multiplication can only be used for $(m2^k \times m2^k)$ matrices. For arbitrary $(n \times n)$ matrices one has to add zero rows and columns to the given matrices to use Strassen's algorithm. Strassen gave a strategy of how to set $m$ and $k$ for arbitrary $n$ to ensure $n\leq m2^k$. In this paper we study the number $d$ of additional zero rows and columns and the influence on the number of flops used by the algorithm in the worst case ($d=n/16$), best case ($d=1$) and in the average case ($d\approx n/48$). The aim of this work is to give a detailed analysis of the number of additional zero rows and columns and the additional work caused by Strassen's bad parameters. Strassen used the parameters $m$ and $k$ to show that his matrix multiplication algorithm needs less than $4.7n^{\log_2 7}$ flops. We can show in this paper, that these parameters cause an additional work of approx. 20 % in the worst case in comparison to the optimal strategy for the worst case. This is the main reason for the search for better parameters.

description: We present here a criterion to conclude that an abstract SPDE posseses a unique maximal strong solution, which we apply to a three dimensional Stochastic Navier-Stokes Equation. Inspired by the work of [Kato and Lai,1984] in the deterministic setting, we provide a comparable result here in the stochastic case whilst facilitating a variety of noise structures such as additive, multiplicative and transport. In particular our criterion is designed to fit viscous fluid dynamics models with Stochastic Advection by Lie Transport (SALT) as introduced in [Holm,2015]. Our application to the Incompressible Navier-Stokes equation matches the existence and uniqueness result of the deterministic theory. This short work summarises the results and announces two papers [Goodair et al, 2022] which give the full details for the abstract well-posedness arguments and application to the Navier-Stokes Equation.

Enhancing the quantity and quality of leisure-time physical activity participation among individuals with spinal cord injury who walk
Creators: name: Lawrason, Sarah Victoria Clewes
Publisher: name: University of British Columbia
Year: 2022

description: Individuals with spinal cord injury (SCI) who walk participate in low levels of leisure-time physical activity (LTPA) due to barriers to quality LTPA experiences. Quality LTPA experiences are important as they confer several benefits such as improved well-being. Behavioural interventions that support quantity and quality of LTPA participation are lacking for ambulators with SCI. To support LTPA behaviour, theory-informed, partnered interventions are needed. The purpose of this dissertation was to conduct a series of studies that will aid in understanding and improving the quantity and quality of LTPA participation among individuals with SCI who walk. First, a scoping review was conducted to understand the amounts, types, correlates, and outcomes of physical activity participation for ambulators with SCI. Second, a cross-sectional study, informed by behaviour change theory, was conducted to identify factors related to LTPA participation in individuals with SCI who ambulate. Third, a qualitative study consisting of interviews with ambulators with SCI was conducted to explore the conditions and elements involved in positive and negative quality LTPA experiences. Fourth, using the findings from the first three studies, an LTPA-enhancing mHealth intervention was designed (SCI Step Together). Fifth, an 8-week randomized controlled trial was conducted to assess the feasibility, acceptability, engagement, and preliminary efficacy of the SCI Step Together program. The results of this programmatic, theory-informed series of studies contribute substantively to knowledge regarding LTPA in a sub-population that has been largely ignored. This dissertation revealed that among ambulators with SCI, LTPA levels are generally low and there are few interventions that support their quality LTPA participation. The studies found that factors that contribute to the quantity and quality of LTPA can be mapped onto existing behaviour change and quality participation frameworks. Conditions that influence elements of quality participation are valuable for designing behavioural interventions, like the SCI Step Together program. The SCI Step Together program demonstrated good feasibility, acceptability, engagement, and preliminary efficacy for some psychosocial variables (e.g., basic psychological needs). Overall, researchers and programmers are strongly encouraged to continue to study and develop resources in partnership with ambulators with SCI to encourage quality participation in LTPA.
Nonuniversal Shot Noise in Disordered Quantum Wires with Channel-Number Imbalance

description: The number of conducting channels for one propagating direction is equal to that for the other direction in ordinary quantum wires. However, they can be imbalanced in graphene nanoribbons with zigzag edges. Employing the model system in which a degree of channel-number imbalance can be controlled, we calculate the shot-noise power at zero frequency by using the Boltzmann-Langevin approach. The shot-noise power in an ordinary diffusive conductor is one-third of the Poisson value. We show that with increasing the degree of channel-number imbalance, the universal one-third suppression breaks down and a highly nonuniversal behavior of shot noise appears.

description: Die Bevölkerung von Österreich wird immer älter. Aufgrund dieser demografischen Alterung wird viel im Bereich Ambient Assisted Living (AAL) gearbeitet. AAL umfasst technische Ressourcen, die es älteren betreuungsbedüftigen Menschen ermöglichen unabhängig in ihren eigenen vier Wänden zu leben. Daher ist es von Interesse, die wirtschaftlichen Vorteile für Österreich durch den Einsatz von Ambient Assisted Living zu betrachten. Ein Ziel dieser Arbeit ist es diese Vorteile zu zeigen.
Dafür werden Informationen über Pflegekosten in Österreich gesammelt und eine Umfrage wird durchgeführt, um Informationen über Unternehmen und ihre Ambient Assisted Living-Projekten und die Kosten im Zusammenhang mit deren Entwicklung zu bekommen. Nach Analyse der gesammelten Informationen im Hinblick auf den Nutzen für Österreich, kann man sehen, dass große Einsparungen durch den Einsatz von Ambient Assisted Living möglich sind. Aufgrund der Tatsache, dass die Veränderung der Lebensbedingungen für über ein Jahr nach hinten verschoben werden könnten, wird das selbstständige Leben der betreuungsbedürftigen Menschen verlängert. Dadurch kann Österreich viel Geld im Bereich der finanziellen Unterstützung sparen. Das andere Ziel dieser Arbeit war, einen zentralen Anlaufpunkt für AAL zu schaffen. Um dies zu erreichen, wurde eine vorhandene Datenbank erweitert und die gesammelten Informationen über die AAL-Projekte wurden in diese eingefügt.

description: The population of Austria is getting older. Due to this demographic ageing a lot of work is done in the area of Ambient Assisted Living (AAL). AAL includes technical resources that enable older people in need of care to live independently in their own homes. Therefore, it is of interest which economic benefits Austria could have through the use of Ambient Assisted Living. One aim of this thesis is to show this benefits. For this, informations about care costs in Austria will be gathered and a survey is made to get information about companies and their Ambient Assisted Living projects and the costs related to the development of these projects. After an analysis of the collected information with regard to the benefit for Austria, it can be seen that there are major possible savings through the use of Ambient Assisted Living. Due to the fact that the change of living environment could be postponed for over one year, the independent life of people in need of care is extended. Thus, Austria can save a lot of financial support. The other aim of the theses was to create a single point of resource. A database has been extended to contain all gathered information about the AAL projects.

description: Understanding the phase diagram of QCD by measuring fluctuations of conserved charges in heavy-ion collision is one of the main goals of the beam energy scan program at RHIC. Within this work, we calculate the role of hadronic interactions and momentum cuts on cumulants of conserved charges up to fourth order in a system in equilibrium within a hadronic transport approach (SMASH). In our model the net baryon, net charge and net strangeness is perfectly conserved on an event-by-event basis and the cumulants are calculated as a function of subvolume sizes and compared to analytic expectations. We find a modification of the kurtosis due to charge annihilation processes in systems with simplified degrees of freedom. Furthermore the result of the full SMASH hadron gas for the net baryon and net proton number fluctuations is presented for systems with zero and finite values of baryon chemical potential. Additionally we find that due to dynamical correlations the cumulants of the net baryon number cannot easily be recovered from the net protons. Finally the influence of deuteron cluster formation on the net proton and net baryon fluctuations in a simplified system is shown. This analysis is important to better understand the relation between measurements of fluctuations in heavy-ion collisions and theoretical calculation which are often performed in a grand canonical ensemble.
Impact of QCD uncertainties on antiproton spectra from dark-matter annihilation

description: Dark-matter particles that annihilate or decay can undergo complex sequences of processes, including strong and electromagnetic radiation, hadronisation, and hadron decays, before particles that are stable on astrophysical time scales are produced. Antiprotons produced in this way may leave footprints in experiments such as AMS--02. Several groups have reported an excess of events in the antiproton flux in the rigidity range of $10$--$20$ GV. However, the theoretical modeling of baryon production is not straightforward and relies in part on phenomenological models in Monte Carlo event generators. In this work, we assess the impact of QCD uncertainties on the spectra of antiprotons from dark-matter annihilation. As a proof-of-principle, we show that for a two-parameter model that depends only on the thermally-averaged annihilation cross section ($\langle σv \rangle$) and the dark-matter mass ($M_χ$), QCD uncertainties can affect the best-fit mass by up to $\sim 14 \%$ (with large uncertainties for large DM masses), depending on the choice of $M_χ$ and the annihilation channel ($b\bar{b}$ or $W^+ W^-$), and $\langle σv \rangle$ by up to $\sim 10\%$. For comparison, changes to the underlying diffusion parameters are found to be within $1\%$--$5\%$, and the results are also quite resilient to the choice of cosmic-ray propagation model. These findings indicate that QCD uncertainties need to be included in future DM analyses. To facilitate full-fledged analyses, we provide the spectra in tabulated form including QCD uncertainties and code snippets to perform mass interpolations and quick DM fits. The code can be found in this \href{https://github.com/ajueid/qcd-dm.github.io.git}{github} repository.

Quantum thermalization of two coupled two-level systems in eigenstate and bare-state representations

description: We study analytically the quantum thermalization of two coupled two-level systems (TLSs), which are connected with either two independent heat baths (IHBs) or a common heat bath (CHB). We understand the quantum thermalization in eigenstate and bare-state representations when the coupling between the two TLSs is stronger and weaker than the TLS-bath couplings, respectively. In the IHB case, we find that when the two IHBs have the same temperatures, the two coupled TLSs in eigenstate representation can be thermalized with the same temperature as those of the IHBs. However, in the case of two IHBs at different temperatures, just when the energy detuning between the two TLSs satisfies a special condition, the two coupled TLSs in eigenstate representation can be thermalized with an immediate temperature between those of the two IHBs. In bare-state representation, we find a counterintuitive phenomenon that, under some conditions, the temperature of the TLS connected with the high-temperature bath is lower than that of the other TLS, which is connected with the low-temperature bath. In the CHB case, the coupled TLSs in eigenstate representation can be thermalized with the same temperature as that of the CHB in nonresonant cases. In bare-state representation, the TLS with a larger energy separation can be thermalized to a thermal equilibrium with a lower temperature. In the resonant case, we find a phenomenon of anti-thermalization. We also study the steady-state entanglement between the two TLSs in both the IHB and CHB cases.

Spatial dimensions and dynamics of bushmeat hunting : predicting defaunation and managing for sustainability
Creators: name: Deith, Mairin
Publisher: name: University of British Columbia
Year: 2022

description: Humanity continues to depend on wild meat for subsistence and livelihoods, particularly in the Global South. Here, harvest sustainability is often undermined by ineffective wildlife management, exacerbated by limited data and research capacity. A key challenge to decision makers, then, is how to manage harvest systems in the face of data scarcity. The goal of this dissertation is to provide data-limited decision support tools for wild meat management, with particular focus on (1) predicting effort distribution across large scales, and (2) assessing spatial management strategies’ ability to robustly meet conservation and harvest goals. In my first chapter, I developed a novel hunter movement model based on landscape resistance and circuit theoretic algorithms. These algorithms build on commonly used accessibility metrics by incorporating diffusive, multi-path movement from settlements into surrounding landscapes. To facilitate broad application, I built the landscape-scale map from freely available geospatial datasets and open source software. Validating this approach with camera trap observations of hunters from Malaysian Borneo, I found that the new accessibility metric had far more explanatory power than any other accessibility-based or environmental predictor. To assess other drivers of spatial foraging patterns, in my second chapter I extended my scope across the tropics. Compiling images of foragers taken from cameras in 10 protected areas (PAs), I explored which types of variables—accessibility, wildlife value, or environmental features—best informed forager presence on the landscape. While the results of this chapter should be interpreted cautiously, given limited observations, I found no variable could consistently explain observed forager presence across PAs except for elevation. In my final chapter, I leveraged simulations and decision analysis to assess traditional spatial management. I found that large, fixed reserves could robustly maximize both harvest and conservation goals, especially compared to strategies with small or dynamic alternatives. However, outcomes were strongly influenced by the intensity of hunting effort, hunters’ adherence to spatial rules, and mammal dispersal patterns. While the models and simulations I apply here do not capture the full diversity of hunter behaviour and game responses, they can provide guidance and insights where local data collection is infeasible.

description: We study the first order phase transition of Euler-Heisenberg-AdS black hole based on free energy landscape. By solving the Fokker-Planck equation, we research the probability distribution of the system states. The small (large) black hole can have the chance to switch to the large (small) black hole due to the change of the temperature $T$ or Euler-Heisenberg parameter $a$. A higher (lower) $T$ corresponds to a larger probability for a large (small) black hole. The coexistent small and large black hole states can be acquired for some conditions. For $0< a\leq \frac{32}{7} Q^2 $, the small-large black hole phase transition can be acquired with a small $a$. The probability of small (large) black holes will decrease to zero for a large $a$. For a small $a$, a higher peak of the first passage time can be acquired for higher (lower) $T$ or smaller (larger) $a$ with the initial small (large) black hole state. For $a<0$, a smaller (larger) $a$ corresponds to a larger probability for a large (small) black hole. A higher peak of the first passage time can also be obtained for higher (lower) $T$ or smaller (larger) $a$ with initial small (large) black hole state.

description: Renewed interest in deriving gravity (more precisely, the Einstein equations) from thermodynamics considerations [1, 2] is stirred up by a recent proposal that 'gravity is an entropic force' [3] (see also [4]). Even though I find the arguments justifying such a claim in this latest proposal rather ad hoc and simplistic compared to the original one I would unreservedly support the call to explore deeper the relation between gravity and thermodynamics, this having the same spirit as my long-held view that general relativity is the hydrodynamic limit [5, 6] of some underlying theories for the microscopic structure of spacetime - all these proposals, together with that of [7, 8], attest to the emergent nature of gravity [9]. In this first paper of two we set the modest goal of studying the nonequilibrium thermodynamics of classical matter only, bringing afore some interesting prior results, without invoking any quantum considerations such as Bekenstein-Hawking entropy, holography or Unruh effect. This is for the sake of understanding the nonequilibrium nature of classical gravity which is at the root of many salient features of black hole physics. One important property of gravitational systems, from self-gravitating gas to black holes, is their negative heat capacity, which is the source of many out-of-the ordinary dynamical and thermodynamic features such as the non-existence in isolated systems of thermodynamically stable configurations, which actually provides the condition for gravitational stability. A related property is that, being systems with long range interaction, they are nonextensive and relax extremely slowly towards equilibrium. Here we explore how much of the known features of black hole thermodynamics can be derived from this classical nonequilibrium perspective. A sequel paper will address gravity and nonequilibrium thermodynamics of quantum fields [10].

description: In this paper, we show that the adaptive projected subgradient method (APSM) is bounded perturbation resilient. To illustrate a potential application of this result, we propose a set-theoretic framework for MIMO detection, and we devise algorithms based on a superiorized APSM. Various low-complexity MIMO detection algorithms achieve excellent performance on i.i.d. Gaussian channels, but they typically incur high performance loss if realistic channel models (e.g., correlated channels) are considered. Compared to existing low-complexity iterative detectors such as individually optimal large-MIMO approximate message passing (IO-LAMA), the proposed algorithms can achieve considerably lower symbol error ratios over correlated channels. At the same time, the proposed methods do not require matrix inverses, and their complexity is similar to IO-LAMA.

description: Membership of stars in open clusters is one of the most crucial parameters in studies of star clusters. Gaia opened a new window in the estimation of membership because of its unprecedented 6-D data. In the present study, we used published membership data of nine open star clusters as a training set to find new members from Gaia DR2 data using a supervised random forest model with a precision of around 90\%. The number of new members found is often double the published number. Membership probability of a larger sample of stars in clusters is a major benefit in determination of cluster parameters like distance, extinction and mass functions. We also found members in the outer regions of the cluster and found sub-structures in the clusters studied. The color magnitude diagrams are more populated and enriched by the addition of new members making their study more promising. We compared this to unsupervised techniques using Gaussian Mixture Modelling to discuss the various caveats .

description: The construction of amplitudes on curved space-times is a major challenge, particularly when the background has non-constant curvature. We give formulae for all tree-level graviton scattering amplitudes in curved self-dual radiative space-times; these are chiral, source-free, asymptotically flat spaces determined by free characteristic data at null infinity. Such space-times admit an elegant description in terms of twistor theory, which provides the powerful tools required to exploit their underlying integrability. The tree-level S-matrix is written in terms of an integral over the moduli space of holomorphic maps from the Riemann sphere to twistor space, with the degree of the map corresponding to the helicity configuration of the external gravitons. For the MHV sector, we derive the amplitude directly from the Einstein-Hilbert action of general relativity, while other helicity configurations arise from a natural family of generating functionals and pass several consistency checks. The amplitudes in self-dual radiative space-times exhibit many novel features that are absent in Minkowski space, including tail effects. There remain residual integrals due to the functional degrees of freedom in the background space-time, but our formulae have many fewer such integrals than would be expected from space-time perturbation theory. In highly symmetric special cases, such as self-dual plane waves, the number of residual integrals can be further reduced, resulting in much simpler expressions for the scattering amplitudes.

description: The thermal entanglement of the Hubbard dimer (two-site Hubbard model) has been studied with the nonextensive statistics. We have calculated the auto-correlation ($O_q$), pair correlation ($L_q$), concurrence ($Γ_q$) and conditional entropy ($R_q$) as functions of entropic index $q$ and the temperature $T$. The thermal entanglement is shown to considerably depend on the entropic index. For $q < 1.0$, the threshold temperature where $Γ_q$ vanishes or $R_q$ changes its sign is more increased and the entanglement may survive at higher temperatures than for $q=1.0$. Relations among $L_q$, $Γ_q$ and $R_q$ are investigated. The physical meaning of the entropic index $q$ is discussed with the microcanonical and superstatistical approaches. The nonextensive statistics is applied also to Heisenberg dimers.

description: It was shown by Bishop that if Thurston's $K = 2$ conjecture holds for some planar domain, then Brennan's conjecture holds for the Riemann map of that domain as well. In this paper we show numerically that the original counterexample to Thurston's $K=2$ conjecture given by Epstein, Marden and Marković is not a counterexample to Brennan's conjecture.

description: We report the first unambiguous observation of a fractional quantum Hall state in the Landau level of a two-dimensional hole sample at the filling factor $ν=8/3$. We identified this state by a quantized Hall resistance and an activated temperature dependence of the longitudinal resistance and found an energy gap of 40 mK. To our surprise the particle-hole conjugate state at filling factor $ν=7/3$ in our sample does not develop down to 6.9 mK. This observation is contrary to that in electron samples in which the 7/3 state is typically more stable than the 8/3 state. We present evidence that the asymmetry between the 7/3 and 8/3 states in our hole sample is due to Landau level mixing.

description: This paper extends the results of the previous work of the authors on the classification on noncommutative domain algebras up to completely isometric isomorphism. Using Sunada's classification of Reinhardt domains in $C^n$, we show that aspherical noncommutative domain algebras are isomorphic if and only if their defining symbols are equivalent, in the sense that one can be obtained from the other via permutation and scaling of the free variables. Our result also shows that the automorphism groups of aspherical noncommutative domain algebras consists of a subgroup of some finite dimensional unitary group. We conclude by illustrating how our methods can be used to extend to noncommutative domain algebras some results from analysis in $C^n$ with the example of Cartan's lemma.

description: Vermischung spielt bei der Auslegung, Optimierung und Betriebsweise großer Wirbelschichten eine Schlüsselrolle um deren Effizienz zu steigern. Diese Arbeit untersucht das seitliche Mischverhalten in einem Kaltmodell einer Blasenbildenden Wirbelschicht bei unterschiedlichen, zum Vergasungs- und Verbrennungsprozess passenden, Betriebsbedingungen. Die Analysen wurden mittels digitaler Bildanalyse durchgeführt. Dafür wurde ein Objektdetektierungsalgorithmus entwickelt und validiert. Anschließend wurden zwei theoretisch unterschiedliche Modelle implementiert (Einzelpartikelverfolgung, multiple Partikelstreuung). Alle für die Auswertung notwendigen Parameter wurden untersucht. Dabei wurde der Einfluss der Mischzellenbreite bei der Einzelpartikelverfolgungsmethode gefunden. Ohne diesen Parameter, welcher weitere Untersuchungen benötigt, können nur Größenbereiche der Dispersionskoeffizienten angegeben werden. Die Verläufe von beiden Methoden sind miteinander vergleichbar. Dennoch sind jene Werte der Einzelpartikelverfolgung höher. Hinaufskalierte Dispersionskoeffizienten der Einzelpartikelverfolgung liegen in einem Bereich zwischen 0.0064 und 0.112m2s-1 was sie vergleichbar mit Literaturwerten (0.0001 bis 0.1m2s-1) macht.
description: Mixing is an important key issue in large fluidized beds to design, optimize and control the reactors efficiency. This thesis investigates lateral fuel mixing in a cold flow model at several operation conditions, relevant to gasification and combustion processes. The analysis was done with digital image analysis. A new object detection algorithm was developed and validated. Furthermore two different analysis models were developed (single particle tracking and multiple particle spreading). Further on several algorithm settings are investigated. Thereby the influence of the mixing cell length on single particle tracking was found out. Without this parameter, which needs further investigation, only a range of dispersion coefficients can be given. The trends of both methods are comparable. Nevertheless the values are higher for the single particle tracking method. Scaled up single particle tracking dispersion coefficient results are in the range of 0.0064 to 0.112m2s-1 which makes them comparable to those found in literature (0.0001 to 0.1m2s-1).
