description: A mezőgazdaság foglalkoztatásban betöltött szerepének visszaesése a nemzetközi tendenciákhoz hasonlóan Magyarországon is tapasztalható. Az élőmunka-felhasználás mérséklődését a rendszerváltozás okozta társadalmi, gazdasági változások, továbbá a modern technológiák alkalmazása, a termelési szerkezet leegyszerűsödése, valamint a specializáció és a koncentráció mellett főként a nemzetgazdaság más ágazataiban elérhető magasabb jövedelmek és a kedvezőbb munkakörülmények gyorsították fel az elmúlt évtizedekben. Ennek ellenére a vidéki megélhetés egyik alapvető forrása a mezőgazdaság maradt, melynek önellátási, foglalkoztatási és jövedelemtermelő szerepe összehangolt, célzott, a tényleges fejlesztési szükségletekre reagáló szakpolitikai beavatkozások alkalmazása mellett akár tovább erősödhet. Nemzetgazdasági szempontból elsősorban a piaci lehetőségek kihasználására épülő foglalkoztatásbővítés teremthet fenntartható munkahelyeket. Emellett az ökoszociális célú tevékenységek bővítése is rejt magában mezőgazdasági munkahely-teremtési lehetőségeket. ---------------- Similar to international trends, the decline of the role of agriculture in employment can be also observed in Hungary,. The decline of labor-use was accelerated by social and economic changes as a result of the transition after the fall of socialism. In agriculture, the use of modern technologies, the simplification of production structure, specialization and concentration, the higher income available in other spheres of national economy, as well as more favorable working conditions have led to an outfl ow of labor in the last decades. Nevertheless, one of the most fundamental sources of rural livelihood is still the agriculture, whose role concerning self-sufficiency, employment and income-generation can be strengthened by appropriately targeted measures in order to implement effective policy interventions responsive to existing development needs. In economic terms, sustainable jobs can be created by an employment policy, which is primarily based on the exploitation of market opportunities. Apart from this, the expansion of eco-social activities also includes opportunities for job creation in agriculture.

description: Ziel dieser Arbeit ist die methodische Behandlung einer Pfadplanung und die anschließende Pfadfolgeregelung für mechanische Systeme. Der vorliegende Text ist in zwei Teile gegliedert, die jeweils einem dieser Probleme gewidmet sind. Im ersten Teil wird mittels der so genannten Rapidly Exploring Random Trees (schnell erkundende zufällige Bäume) ein allgemeines Pfadplanungsproblem gelöst. Dieses besteht aus der Forderung einen Pfad zwischen zwei definierten Punkten eines Raumes zu finden, der durch Hindernisse beschränkt ist. Mittels einer Erweiterung des Algorithmus können optimale Pfade, im Sinne eines spezifizierten Kriteriums, gefunden werden. Durch geeignete Annahmen lässt sich dieses Problem auf eine weite Klasse mechanischer Systeme anwenden. Der so gewonnene Pfad soll weiters durch ein mechanisches System gefolgt werden. Zu diesem Zweck wurde ein neuer Ansatz für eine Pfadfolgeregelung entwickelt. Hierbei ist nicht nur die Verfolgung des Pfades, sondern auch eine unabhängige Spezifikation der Reaktion auf Abweichungen möglich. Alle beschriebenen Methoden werden anhand geeigneter Simulationen analysiert und ausgewertet. Diesbezüglich wurden mechanische Systeme mit unterschiedlichen Charakteristika herangezogen, um die gewählten Ansätze zu illustrieren. Die Validierung der beschriebenen Methoden mithilfe eines drei-achsigen Parallelroboters untermauert deren praktische Anwendbarkeit.
description: The goal of this thesis is to provide systematic means to plan and follow a path for mechanical systems. Therefore, this thesis is divided into two main parts, one for each of these problems. Firstly, the path planning problem is introduced and then solved by using the so-called Rapidly Exploring Random Tree algorithm. To improve the so-found paths, a modification is introduced which renders the solutions optimal with respect to a specific criterion. To avoid high computation times, the algorithm was simplified by consistent assumptions on the mechanical system. Secondly, a path following controller is derived to follow the calculated path in presence of disturbances and to account for modelling errors. Using this controller, it is possible to control the velocity along the path with one control law and a second control law is defined to account for deviations from the path. To the best of the authors knowledge, this controller, unlike for any other approach, can be specified in fixed coordinates. This particularly simple approach is applicable to a wide variety of systems, in particular mechanical systems. In simulation the proposed concepts were tested for a number of mechanical systems. To underline its practical feasibility the path following approach was validated using a parallel kinematic robot.

description: Napjainkban a világ, illetve az Európai Unió legtöbb tagországára is igaz, hogy jelentős fejlettségbeli különbségek vannak az országhatárokon belül és kívül egyaránt. Jelentős fejlettségbeli eltérést mutatnak a városi, illetve a vidéki területek. A területi egyenlőtlenségek kialakulásának legfőbb oka, hogy a gazdasági-társadalmi folyamatok térben és időben szüntelenül újrarendeződnek, és e tényezők a világ globalizálódásával csak tovább fokozódnak. A hátrányos helyzetből való kitörésre az időben és térben lejátszódott, illetve folyamatosan működő területi egyenlőtlenségi folyamatoknak és azok térszerkezeti változásokra gyakorolt hatásainak átfogó ismerete adhat lehetőséget. Ebben a sokváltozós viszonyrendszerben az újabb és újabb fejlesztési stratégiák kidolgozását meggyőződésem szerint elsősorban a régiókon belüli lehetőségekre, az endogén potenciálok kiaknázására, a saját erők megújítására és fejlesztésére kell alapozni az adott térségekben. De felmerül a kérdés: mi várható az alulról induló, az endogén forrásokra épülő fejlesztésektől, hiszen az endogén forrásokra alapozott fejlesztésnek nyilvánvalóan mások és mások a lehetőségei a térségek területi különbségeit is figyelembe véve. Mindezek alapján is jól látható, hogy nincs egységes megoldási séma a területi különbségek mérséklésére, így fontos a hátrányos helyzet kialakulásának ismerete, elemzése, ami nem nélkülözheti a természeti és a gazdasági tényezők mellett a társadalmi folyamatok részletes vizsgálatát. ---------------- It is true for most countries that there are significant inequalities in development both within their borders and beyond. Urban and rural areas show significant differences in the level of development. The reason for the creation of spatial discrepancies is that the economic and social processes are always restructured in space and time and such processes are even accelerated by globalisation. There are restructuring and relocating processes under way both in Europe and beyond. In order to gain a precise and realistic picture of territorial processes, it is worth learning the spatial processes that have already happened and their impacts on the spatial structure, since these may enable us to break out from the disadvantaged situation.

description: Measurements of the persistent current in a ring containing a quantum dot would afford a unique opportunity to finally detect the elusive Kondo screening cloud. We present the first large-scale numerical results on this controversial subject using exact diagonalization and density matrix renormalization group (RG). These extremely challenging numerical calculations confirm RG arguments for weak to strong coupling crossover with varying ring length and give results on the universal scaling functions. We also study, analytically and numerically, the important and surprising effects of particle-hole symmetry breaking.

title: The Epidemiology and Control of Human Influenza in Vietnam
Creators: name: Pham, Quang Thai
Publisher: name: The Open University

description: Understanding the epidemiology of human influenza in Viet Nam is important for developing local policies and also for understanding the dynamics of influenza in tropical and subtropical southeast Asia. I have analysed an 18 year time-series of influenza-like-illness (ILI) surveillance data, and assessed the relationship of this time-series with climate variables and with sentinel influenza virus surveillance data. I also conducted a study of influenza A/H1N1 transmission within households. ILI notifications in Viet Nam show a latitudinal gradient, with seasonality in the north but no seasonal pattern observed in low lying areas of central and southern Viet Nam. Seasonality is however observed in the elevated provinces of central Viet Nam, suggesting that the seasonal patterns are driven by climate. Principal component analysis finds that temperature and absolute humidity (AH) are positively correlated and together explain around 59% of total climatic variance, and that there is a strong latitudinal gradient in these variables. Regression tree analysis shows that provinces with strong seasonality of AH have strong ILI seasonality. Although virological surveillance data are limited, increases in ILI notifications are associated with an increase in the proportion of upper respiratory tract swabs that are influenza positive. In a prospective study of H1N1/2009 transmission in a household-based cohort, 11 of 59 household contacts were infected, giving a household secondary infection risk of 18.6% (95%CI 10.7-30.4%), but 5 (45%) did not develop symptoms. Virus genetic sequencing indicated that 10 of the 11 secondary cases (91%) were probably infected within the household rather than from the community. This research provides new insights into the seasonality and climatic determinants of ILI and influenza epidemiology in Viet Nam, and on the transmission of influenza within households. The findings are valuable for national influenza control policies and also add to the current state of knowledge of influenza epidemiology.

description: We consider multipartite quantum state discrimination and provide a specific relation between the properties of entanglement witness and quantum nonlocality inherent in the confidence of measurements. We first provide the definition of the confidence of measurements as well as its useful properties for various types of multipartite measurements. We show that globally maximum confidence that cannot be achieved by local operations and classical communication strongly depends on the existence of entanglement witness. We also provide conditions for an upper bound on maximum of locally-achievable confidences. Finally, we establish a method in terms of entanglement witness to construct quantum state ensemble with nonlocal maximum confidences.

description: Über die Koralmbahn zwischen Graz und Klagenfurt wird eine Wildbrücke als Schalenbrücke mit dem Pneumatic Forming of Hardened Concrete (PFHC) Bauverfahren hergestellt. Die doppelt gekrümmte Schale der Brücke wird dabei durch das Anheben einer ebenen ausgehärteten Betonplatte mit Hilfe einer pneumatischen Schalung errichtet. Diese Diplomarbeit beinhaltet die Beschreibung und Auswertung einer Serie von 16 vorab durchgeführten Biegeversuchen an rechteckigen Betonplatten, mit dem Ziel die geeignetste Beton-Bewehrungskombination für den Umformungsprozess von der Platte zur Schale zu bestimmen. Mit einem an den Versuchsergebnissen kalibrierten numerischen Modell der Biegeexperimente werden zweidimensionale nichtlineare Analysen zu den Versagensmechanismen und der Variation des Bewehrungsgrades durchgeführt. Abschließend wird eine dreidimensionale nichtlineare Simulation des Umformungsprozesses vorgestellt und ausgewählte praxisrelevante Ergebnisse werden präsentiert.
description: A shell-shaped concrete bridge is going to be erected along the railway line Koralmbahn between Graz and Klagenfurt using the Pneumatic Forming of Hardened Concrete (PFHC) construction method. The double-curved shell of the deer pass is built by lifting an initially flat hardened concrete plate with the aid of a pneumatic formwork and additional post tensioning cables at the circumference. This master-s thesis includes the description and analysis of a series of 16 preliminary four-point bending tests on rectangular concrete specimen. The aim is to determine the most suitable concrete-reinforcement combination for the transformation process from the plate to the shell. Using a numerical model of the bending experiments, which is calibrated to the test results, two-dimensional nonlinear analyses of failure mechanisms and variations of the reinforcement ratio are executed. Finally, the thesis describes a three-dimensional nonlinear simulation of the transformation process and presents some particularly chosen results.

WMAP Microwave Emission Interpreted as Dark Matter Annihilation in the Inner Galaxy
Creators: name: Finkbeiner, Douglas P.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Excess microwave emission observed in the inner Galaxy (inner ~1 kpc) is consistent with synchrotron emission from highly relativistic electron-positron pairs produced by dark matter particle annihilation. More conventional sources for this emission, such as free-free (thermal bremsstrahlung), thermal dust, spinning dust, and the softer Galactic synchrotron traced by low-frequency surveys, have been ruled out. The total power observed in the range 23 < nu < 61 GHz is between 10^{36} and 5x10^{36} erg/s, depending on the method of extrapolation to the Galactic center, where bright foreground emission obscures the signal. The inferred electron energy distribution is diffusion hardened, and is in qualitative agreement with the energy distribution required to explain the gamma ray excess in the inner Galaxy at 1-30 GeV as inverse-Compton scattered starlight. We investigate the possibility that this population of electrons is produced by dark matter annihilation of 100 GeV particles, with cross section =2x10^{-26} cm^3/s, and an 1/r dark matter mass profile truncated in the inner Galaxy, and find this scenario to be consistent with current data.

description: We determine the Shimura modular curve X_0(3) and the Jacobian of the Shimura modular curve X_1(3) associated with the congruence subgroups Gamma_0(3), Gamma_1(3) of the (2,3,7) triangle group. This group is known to be arithmetic and associated with a quaternion algebra A/K ramified at two of the three real places of K=Q(\cos 2π/7) and at no finite primes of K. Since the rational prime 3 is inert in K, the covering X_0(3)/X(1) has degree 28 and Galois group PSL_2(F_27). We determine X_0(3) by computing this cover. We find that X_0(3) is an elliptic curve of conductor 147=3*7^2 over Q, as is the Jacobian J_1(3) of X_1(3); that these curves are related by an isogeny of degree (27-1)/2=13; and that the kernel of the 13-isogeny from J_1(3) to X_0(3) consists of K-rational points. We explain these properties, use X_0(3) to locate some complex multiplication (CM) points on X(1), and describe analogous behavior of a few Shimura curves associated with quaternion algebras over other cyclic cubic fields.

Non-extensive random walks

description: The stochastic properties of variables whose addition leads to $q$-Gaussian distributions $G_q(x)=[1+(q-1)x^2]_+^{1/(1-q)}$ (with $q\in\mathbb{R}$ and where $[f(x)]_+=max\{f(x),0\}$) as limit law for a large number of terms are investigated. These distributions have special relevance within the framework of non-extensive statistical mechanics, a generalization of the standard Boltzmann-Gibbs formalism, introduced by Tsallis over one decade ago. Therefore, the present findings may have important consequences for a deeper understanding of the domain of applicability of such generalization. Basically, it is shown that the random walk sequences, that are relevant to this problem, possess a simple additive-multiplicative structure commonly found in many contexts, thus justifying the ubiquity of those distributions. Furthermore, a connection is established between such sequences and the nonlinear diffusion equation $\partial_t ρ=\partial^2_{xx}ρ^ν$ ($ν\neq1$).

Public health nurse perceptions of their role in early postpartum discharge
Creators: name: Cusack, Cheryl Leah
Publisher: name: University of British Columbia
Year: 2010

description: With early postpartum discharge (EPD), public health nurses (PHNs) are given the responsibility of community-based postpartum follow-up after hospital discharge, to promote the safety and well-being of new mothers and babies. Given the large number of births per year and the requirements for PHN follow-up, EPD has affected PHNs’ workload. The objectives of this qualitative, descriptive study were to: a) describe PHNs’ perceptions of EPD, b) document the effects of EPD on PHN practice, and c) describe the preferred role of PHNs in caring for postpartum women and newborns. The Canadian Health Nurses Association of Canada (CHNAC) standards of practice served as the conceptual framework for the study. Four sets of PHNs in the Winnipeg Regional Health Authority (WRHA) participated in this study through 1- hour focus groups. The data were analysed using an inductive content analysis approach, in the form of constant comparative analysis. Three main themes and 10 sub-themes were identified. The three main themes were: a passion for the public health nurse role, the influence of early postpartum discharge on public health practice, and building a public health nursing future. The findings were discussed, and implications for nursing education, research, administration, practice, and policy described. The findings of this study point to the need to develop new and innovative approaches for providing EPD services to the public.

Improving methods of measuring physical activity for health research : validation of the lifetime physical activity questionnaire (L-PAQ)
Creators: name: De Vera, Mary Abigail
Publisher: name: University of British Columbia
Year: 2010

description: Lifetime physical activity plays an important determinant role in health outcomes including physical fitness, well-being, and development of disease, and the evaluation psychometric properties of instruments measuring this construct are important in epidemiologic studies. This study provided a comprehensive evaluation of the Lifetime Physical Activity Questionnaire (L-PAQ), a novel, Internet-based, self-administered instrument measuring lifetime exposure to physical activity across three domains: sports/recreation, occupation, and domestic. Validation of the L-PAQ involved a test/retest study to evaluate instrument reliability and a two-part construct validity study involving comparison to two questionnaires measuring similar constructs and hypotheses testing of L-PAQ constructs. The L-PAQ demonstrated good reliability with intraclass correlation coefficients for average lifetime hours/week of physical activity ranged from 0.58 to 0.83. The highest reliability was seen for sports (0.83) and lowest for total activity (0.58). Intermediate correlation coefficients were obtained for occupational (0.72) and domestic (0.60) activity. Based on the results of comparison with the LTPAQ, the Lifetime Total Physical Activity Questionnaire, and the CT-PAQ, the Chasan- Taber Physical Activity Questionnaire, the L-PAQ demonstrated very good validity for domestic activity and moderate validity for sports and occupational activity. The robustness of the measurement of lifetime physical activity by the L-PAQ was further supported by the results of hypotheses tests between constructs measured by the questionnaire and descriptors of survey respondents. The relationship between lifetime physical activity measured by the L-PAQ and gender agree with previous findings. In addition, this was the first study to show relationships between lifetime physical activity and education level. Overall, validation studies of the L-PAQ contribute to the existing knowledge of measurement of lifetime physical activity and provide evidence for the utility of this instrument.

In this note we provide a stringy embedding of this mechanism through the Green-Schwarz mechanism, demonstrating that if the model-independent axion is the source of the gravitational waves responsible for the lepton asymmetry, one can observationally constrain the string scale and coupling.

description: We study the sensitivity of fixed target experiments to hadronically-coupled axion like particles (ALPs) produced in kaon decays, with a particular emphasis on current and upcoming short-baseline neutrino experiments. We demonstrate that below the kaon decay mass threshold ($m_a < m_K - m_π$) kaon decay is the dominant production mechanism for ALPs at neutrino experiments, larger by many orders of magnitude than production in psuedo-scalar mixing. Such axions can be probed principally by the di-photon and di-muon final states. In the latter case, even if the axion does not couple to muons at tree level, such a coupling is induced by the renormalization group flow from the UV scale. We reinterpret prior results by CHARM and MicroBooNE through these channels and show that they constrain new areas of heavy axion parameter space. We also show projections of the sensitivity of the SBN and DUNE experiments to axions through these channels, which reach up to multiple decades higher in the axion decay constant beyond existing constraints. DUNE projects to have a sensitivity competitive with other world-leading upcoming experiments.

description: Giant arcs in strong lensing galaxy clusters can provide a purely geometric determination of cosmological parameters, such as the dark energy density and equation of state. We investigate sources of noise in cosmography with giant arcs, focusing in particular on errors induced by density fluctuations along the line-of-sight, and errors caused by modeling uncertainties. We estimate parameter errors in two independent ways, first by developing a Fisher matrix formalism for strong lensing parameters, and next by directly ray-tracing through N-body simulations using a multi-plane lensing code. We show that for reasonable power spectra, density fluctuations from large-scale structure produce > 100% errors in cosmological parameters derived from any single sightline, precluding the use of individual clusters or golden lenses to derive accurate cosmological constraints. Modeling uncertainties similarly can lead to large errors, and we show that the use of parametrized mass models in fitting strong lensing clusters can significantly bias the inferred cosmological parameters. We lastly speculate on means by which these errors may be corrected.

Canonical and DLPNO-based composite wavefunction methods parametrized against large and chemically diverse training sets. 2. Correlation consistent basis sets, core-valence correlation, and F12 alternatives

description: A hierarchy of wavefunction composite methods (cWFT), based on G4- type cWFT methods available for elements H through Rn, was recently reported by Semidalas and Martin [J. Chem. Theor. Comput. 2020, 16, 4238]. We extend this hierarchy by considering the inner-shell correlation energy in the second-order Moller-Plesset correction and replacing the Weigend-Ahlrichs def2-mZVPP(D) basis sets used in the aforementioned paper with complete basis set extrapolation from augmented correlation consistent core-valence triple-zeta, aug-cc-pwCVTZ(-PP), and quadruple-zeta, aug-cc-pwCVQZ(-PP), basis sets, thus creating cc-G4- type methods. For the large and chemically diverse GMTKN55 benchmark suite, they represent a substantial further improvement and bring WTMAD2 (weighted mean absolute deviation) down below 1 kcal/mol. Intriguingly, the lion's share of the improvement comes from better capture of valence correlation; the inclusion of core-valence correlation is almost an order of magnitude less important. These robust correlation consistent cWFT methods approach the CCSD(T) complete basis limit with just one or a few fitted parameters. Particularly the DLPNO variants such as cc-G4-T-DLPNO are applicable to fairly large molecules at modest computational cost, as is (for a reduced range of elements) a different variant using MP2-F12/cc-pVTZ-F12 for the MP2 component.

Constraints on the role of synchrotron X-rays from jets of accreting black holes
Creators: name: Heinz, S.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We present an extension of the scale invariance formalism by Heinz & Sunyaev (2003) which includes the effects of radiative cooling on the X-ray synchrotron emission from core dominated jets and outflows. We derive the scaling relations between the radio luminosity L_r, the synchrotron X-ray luminosity L_x, the mass M, and the accretion rate of an accreting black hole. We argue that the inclusion of synchrotron losses into the scaling relations is required by the data used in Merloni, Heinz, & DiMatteo (2003) to define the "fundamental plane'' correlation between L_r, L_x, and M in AGNs and Galactic X-ray binaries. We then fit the new scaling relations to the "fundamental plane" correlation. This allows us to derive statistical constraints on the contribution from jet synchrotron emission to the X-rays from black holes, or, alternatively, on the particle acceleration scheme at work in these jets. We find that, in order for jet synchrotron X-rays to be consistent with the observed "fundamental plane" correlation, the global particle spectrum must be both steep: f(gamma) ~ gamma^(-(3.4 (+0.6-0.5)), and unbroken down to energies well below the radio synchrotron regime. Such a steep particle distribution would imply steeper X-ray spectra than observed in most sources contributing to the correlation with avalailable X-ray spectral index measurements. We suggest that, unless some assumptions of the scale invariance hypothesis are broken, another emission mechanism (likely either disk radiation and/or inverse Compton scattering in the jet) contributes significantly to the X-rays of a sizeable fraction of the sources.

title: Distilling Mobile Privacy Requirements from Qualitative Data
Creators: name: Thomas, Keerthi
Publisher: name: The Open University
Year: 2014

description: As mobile computing applications have become commonplace, it is increasingly important for them to address end-users' privacy requirements. Mobile privacy requirements depend on a number of contextual socio-cultural factors to which mobility adds another level of contextual variation. However, traditional requirements elicitation methods do not sufficiently account for contextual factors and therefore cannot be used effectively to represent and analyse the privacy requirements of mobile end users. On the other hand, methods that investigate contextual factors tend to produce data which can be difficult to use for requirements modelling. To address this problem, we have developed a Distillation approach that employs a problem analysis model to extract and refine privacy requirements for mobile applications from raw data gathered through empirical studies involving real users. Our aim was to enable the extraction of mobile privacy requirements that account for relevant contextual factors while contributing to the software design and implementation process. A key feature of the distillation approach is a problem structuring framework called privacy facets (PriF). The facets in the PriF framework support the identification of privacy requirements from different contextual perspectives namely - actors, information, information-flows and places. The PriF framework also aids in uncovering privacy determinants and threats that a system must take into account in order to support the end-user's privacy. In this work, we first show the working of distillation using qualitative data taken from an empirical study which involved social-networking practices of mobile users. As a means of validating distillation, another distinctly separate qualitative dataset from a location-tracking study is used, in both cases, the empirical studies relate to privacy issues faced by real users observed in their mobile environment.

description: We make an exploratory study of how well dark energy models can be constrained using lensed arcs at different redshifts behind cluster lenses. Arcs trace the critical curves of clusters, and the growth of critical curves with source redshift is sensitive to the dark-energy equation of state. Using analytical models and numerically simulated clusters, we explore the key factors involved in using cluster arcs as a probe of dark energy. We quantify the sensitivity to lens mass, concentration and ellipticity with analytical models that include the effects of dark energy on halo structure. We show with simple examples how degeneracies between mass models and cosmography may be broken using arcs at multiple redshifts or additional constraints on the lens density profile. However we conclude that the requirements on the data are so stringent that it is very unlikely that robust constraints can be obtained from individual clusters. We argue that surveys of clusters, analyzed in conjunction with numerical simulations, are a more promising prospect for arc-cosmography. We use such numerically simulated clusters to estimate how large a sample of clusters/arcs could provide interesting constraints on dark energy models. We focus on the scatter produced by differences in the mass distribution of individual clusters. We find from our sample of simulated clusters that at least 1000 pairs of arcs are needed to obtain constraints if the mass distribution of individual clusters is taken to be undetermined. We discuss several unsolved problems that need study to fully develop this method for precision studies with future surveys.
