description: Das Recht auf Datenportabilität erlaubt Nutzerinnen und Nutzern, ihre bei einem Online-Dienst gespeicherten Daten abzurufen und zu anderen Diensten zu transferieren. Zwar müssen Anbieter Datenportabilität ermöglichen, doch wird sie bisher nur selten aktiv kommuniziert. Eine Ursache hierfür kann in wenig gesichertem Wissen über Effekte von Datenportabilität auf die Bewertung von Diensten gesehen werden. Diese Studie untersucht daher auf Basis einer Conjoint-Analyse (N = 395) exemplarisch, wie aktives Kommunizieren von Datenportabilität die Nutzungsbereitschaft für E-Mail-Dienste beeinflusst. Die Ergebnisse zeigen, dass Kundinnen und Kunden Angebote bevorzugen, die explizit auf Datenportabilität hinweisen, dass ein solcher Hinweis die Zahlungsbereitschaft erhöhen kann, und dass Individuumsvariablen wie Technikkompetenz dabei eine Rolle spielen. Die Studie legt somit nahe, dass die Attraktivität von Online-Diensten durch aktives Kommunizieren von Datenportabilität erhöht werden kann. Empfehlungen zur nutzerfreundlichen Gestaltung von Datenportabilitätshinweisen werden abgeleitet und Implikationen für die weitere Forschung diskutiert.
description: The right to data portability allows users to retrieve their data stored with an online service and transfer it to other services. Although service providers must make data portability possible, it is rarely actively communicated. One reason for this can be seen in the lack of reliable knowledge about the effects of data portability on users’ perception of services. This study therefore uses a conjoint analysis (N = 395) to investigate how actively communicating data portability influences the willingness to use e-mail services. The results show that customers prefer offers that explicitly advertise data portability, that a portability notification can increase willingness to pay, and that individual variables such as technical competence play a role in this. The study thus suggests that the attractiveness of online services can be increased by actively communicating data portability. Recommendations for the user-friendly design of data portability notices are derived and implications for further research are discussed.

description: This report results from the experience and lessons learned in co-designing the thirteen Cos4Cloud services. The technological services were created from a bottom-up approach, following a co-design process connected to an agile software development methodology. The co-design team implemented the co-design process as a service within the Cos4Cloud consortium, as stated in task 5.2. The result of implementing the co-design framework and methodologies and the corresponding monitoring during the co-design of the services, were evaluated and adapted to be shared with the citizen science community as a methodological guide. The guide was designed in a visual friendly format and published in Zenodo to promote its use by the public. The document it’s available at: https://doi.org/10.5281/zenodo.7472450 The present deliverable includes an introduction to the world of co-design, where the main definitions and mindsets of co-design and design thinking are given, as well as some tools to start applying the creative methodologies within them. Secondly, it introduces the co-design methodology followed in Cos4Cloud, together with some important concepts, such as citizen science and citizen observatories. Then, a practical guide of implementation is given, including all the co-design methodologies used in Cos4Cloud. The most standard methods include a description and a work map template, while the customised ones incorporate a step-by-step guide to implement them. Finally, an explanation is given on how the co-design process was implemented in Cos4Cloud as a service for software developers, by using three interactive platforms that allowed us to perform all creative sessions, including the co-design team and community that supported the process. The document concludes with an invitation to implement co-design processes in other software development projects.

description: Relaxation processes driven by a Laplacian matrix can be found in many real-world big-data systems, for example, in search engines on the World-Wide-Web and the dynamic load balancing protocols in mesh networks. To numerically implement such processes, a fast-running algorithm for the calculation of the pseudo inverse of the Laplacian matrix is essential. Here we propose an algorithm which computes fast and efficiently the pseudo inverse of Markov chain generator matrices satisfying the detailed-balance condition, a general class of matrices including the Laplacian. The algorithm utilizes the renormalization of the Gaussian integral. In addition to its applicability to a wide range of problems, the algorithm outperforms other algorithms in its ability to compute within a manageable computing time arbitrary elements of the pseudo inverse of a matrix of size millions by millions. Therefore our algorithm can be used very widely in analyzing the relaxation processes occurring on large-scale networked systems.

description: Redistribution of Cr atoms in a Fe85Cr15 alloy caused by its irradiation with 250 keV He ions to different doses viz. 5, 10 and 30 dpa was investigated by means of conversion electrons Mossbauer spectroscopy. The redistribution was expressed in terms of the Warren-Cowley short-range order parameters alpha1, alpha2 and alpha12 pertaining to the first, second and both neighbor shells, respectively. Clear evidence was found, both for non-irradiated and irradiated samples that the actual distribution of Cr atoms is characteristic of the shell, and for a given shell it depends on the irradiation dose. In particular, alpha1 is positive, hence indicates an under population of Cr atoms in 1NN with respect to the random case, alpha2 is negative, giving evidence thereby that 2NN is overpopulated by Cr atoms, and alpha12 is weakly positive. Under the applied irradiation the number of Cr atoms in both neighbor shells decreased signifying thereby a clustering of Cr atoms. The underlying decrease of Cr concentration within the two-shells volume around the probe Fe atoms was estimated at 1.5 at% ranging between 2.1 for the lowest and 0.8 at% for the highest dose.

Direct reprogramming of adult human fibroblasts: Generation of dopaminergic neurons for cell-based replacement therapy

description: Cell-based replacement therapy has great potential to address the motor symptoms of Parkinson’s disease (PD), a neurodegenerative disease resulting from the progressive loss of dopaminergic cells within the nigrostriatal system. Direct neural reprogramming is a technology where a somatic cell is directly converted into an induced neuron without going through a pluripotent intermediate stage. Induced neurons (iNs) are a unique resource obviating safety concerns associated with pluripotency, as well as ethical concerns with embryonic derived cells, whilst allowing for patient specific cells or matched donors. We have previously shown that dopaminergic (DA) neuronal fate could be generated from human fetal fibroblasts using forced expression of Ascl1 and specific DA fate determinants. However, this early protocol showed low efficiency when converting adult human fibroblasts. Here we build on our reprogramming method to convert human adult fibroblasts into induced dopaminergic neurons (iDANs) with a new combination of transcription factors combined with a RE1-silencing transcription factor (REST) knock-down. High content screening analysis shows that approximately 20% of converted cells express tyrosine hydroxylase (TH) using our new reprogramming cocktail. Furthermore, there is a progressive morphological maturation from day 6 and our iDANs express both mature neuronal and dopaminergic markers. Results provide a more robust and efficient protocol for the generation of iDANs and will help to pave the way for future research assessing their potential for brain repair.

description: We report $^{115}$In nuclear quadrupolar resonance (NQR) measurements on the heavy-fermion superconductor PuCoIn$_5$, in the temperature range $0.29{\rm K}\leq T\leq 75{\rm K}$. The NQR parameters for the two crystallographically inequivalent In sites are determined, and their temperature dependence is investigated. A linear shift of the quadrupolar frequency with lowering temperature below the critical value $T_c$ is revealed, in agreement with the prediction for composite pairing. The nuclear spin-lattice relaxation rate $T_1^{-1}(T)$ clearly signals a superconducting (SC) phase transition at $T_c\simeq 2.3$K, with strong spin fluctuations, mostly in-plane, dominating the relaxation process in the normal state near to $T_c$. Analysis of the $T_1^{-1}$ data in the SC state suggests that PuCoIn$_5$ is a strong-coupling $d$-wave superconductor.

Steady-state planet migration by the Kozai-Lidov mechanism in stellar binaries
Creators: name: Petrovich, Cristobal
Publisher: name: arXiv
Year: 2014
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: We study the steady-state orbital distributions of giant planets migrating through the combination of the Kozai-Lidov (KL) mechanism due to a stellar companion and friction due to tides raised on the planet by the host star. We run a large set of Monte Carlo simulations that describe the secular evolution of a star-planet-star triple system including the effects from general relativistic precession, stellar and planetary spin evolution, and tides. Our simulations show that KL migration produces Hot Jupiters (HJs) with semi-major axes that are generally smaller than in the observations and they can only explain the observations if the following are both true: (i) tidal dissipation at high eccentricities is at least $\sim 150$ times more efficient than the upper limit inferred from the Jupiter-Io interaction; (ii) highly eccentric planets get tidally disrupted at distances $\gtrsim 0.015$ AU. Based on the occurrence rate and semi-major axis distribution of HJs, we find that KL migration in stellar binaries can produce at most $\sim 20\%$ of the observed HJs. Almost no intermediate-period (semi-major axis $\sim0.1-2$ AU) planets are formed by this mechanism - migrating planets spend most of their lifetimes undergoing KL oscillations at large orbital separations ($>2$ AU) or as Hot Jupiters.

description: The main objective of this deliverable, aside from explaining the DUNS conceptualization and development process, is to demonstrate how this service can be integrated and useful in other Cos4Cloud services, such as Cos4Bio (a service that integrates biodiversity observations from multiple COs in one place). We also want to show how DUNS can provide an additional data flow to a citizen science portal such as Natusfera, enriching the portal's information with the goal of improving the community and retaining the people who are part of it and who contribute information with their observations. It is important to note that DUNS is a service that will be available on the EOSC Portal at https://marketplace.eosc-portal.eu/services/. The objective is that DUNS could be integrated into all Citizen Observatories that want to be part of Cos4Bio, and in this way they can receive notifications of use of each and every observation that experts download and use on other platforms through Cos4Bio. Deliverable related to DUNS service.
Long-time behavior of periodically driven isolated interacting lattice systems

description: We study the dynamics of isolated interacting spin chains that are periodically driven by sudden quenches. Using full exact diagonalization of finite chains, we show that these systems exhibit three distinct regimes. For short driving periods, the Floquet Hamiltonian is well approximated by the time-averaged Hamiltonian, while for long periods the evolution operator exhibits properties of random matrices of a Circular Ensemble (CE). In-between, there is a crossover regime. Based on a finite-size scaling analysis and analytic arguments we argue that, for thermodynamically large systems and non-vanishing driving periods, the evolution operator always exhibits properties of CE random matrices. Consequently, the Floquet Hamiltonian is nonlocal and has multi-body interactions; and the driving leads to the equivalent of an infinite temperature state at long times. These results are connected to the breakdown of the Magnus expansion and are expected to hold beyond the specific lattice model considered.

Direct Reprogramming of Adult Human Fibroblasts to Dopaminergic Neurons

description: Parkinson’s disease (PD) is a neurodegenerative disease resulting from the progressive loss of dopaminergic cells within the nigrostriatal system. Previous work has shown that it is possible to generate dopaminergic (DA) neurons from fetal tissue and embryonic stem cells and, when transplanted into animal models of PD, these cells can integrate and provide improvement in motor symptoms. However, in order to translate these into clinical therapies there are a number of logistical and ethical concerns with using cells derived from embryonic sources. With new reprogramming technologies we can now generate DA neurons from somatic cell sources, which also allows for the possibility to use patient specific cells or matched donors. The main purpose of this project is to develop robust protocols for the generation of DA neurons from adult human fibroblasts, from both healthy individuals and PD patients. We will reprogram cells directly into induced neurons (iNs) and investigate if there are any differences in gene expression, morphology or phenotype between the DA neurons generated from healthy, genetic PD, and sporadic PD donors. The results will provide a more robust protocol for the generation of reprogrammed DA neurons from adult donors and will help to pave the way for future research assessing their potential for brain repair and disease modelling.

description: Conditional random fields (CRFs) are popular discriminative models for computer vision and have been successfully applied in the domain of image restoration, especially to image denoising. For image deblurring, however, discriminative approaches have been mostly lacking. We posit two reasons for this: First, the blur kernel is often only known at test time, requiring any discriminative approach to cope with considerable variability. Second, given this variability it is quite difficult to construct suitable features for discriminative prediction. To address these challenges we first show a connection between common half-quadratic inference for generative image priors and Gaussian CRFs. Based on this analysis, we then propose a cascade model for image restoration that consists of a Gaussian CRF at each stage. Each stage of our cascade is semi-parametric, i.e. it depends on the instance-specific parameters of the restoration problem, such as the blur kernel. We train our model by loss minimization with synthetically generated training data. Our experiments show that when applied to non-blind image deblurring, the proposed approach is efficient and yields state-of-the-art restoration quality on images corrupted with synthetic and real blur. Moreover, we demonstrate its suitability for image denoising, where we achieve competitive results for grayscale and color images.

description: We present a systematic investigation of the gain properties of a gas electron multiplier (GEM) foil in pure dimethyl ether (DME) at low pressures. The GEM is made from copper- clad liquid crystal polymer insulator (LCP-GEM) designed for space use, and is applied to a time projection chamber filled with low-pressure DME gas to observe the linear polarization of cosmic X-rays. We have measured gains of a 100 um-thick LCP-GEM as a function of the voltage between GEM electrodes at various gas pressures ranging from 10 to 190 Torr with 6.4 keV X-rays. The highest gain at 190 Torr is about 2x10^4, while that at 20 Torr is about 500. We find that the pressure and electric-field dependence of the GEM gain is described by the first Townsend coefficient. The energy scale from 4.5 to 8.0 keV is linear with non-linearity of less than 1.4% above 30 Torr.

Search for supersymmetry with razor variables in pp collisions at sqrt(s) = 7 TeV

Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Physics - Experiment (hep-ex)
subject: FOS: Physical sciences

description: The razor approach to search for R-parity conserving supersymmetric particles is described in detail. Two analyses are considered: an inclusive search for new heavy particle pairs decaying to final states with at least two jets and missing transverse energy, and a dedicated search for final states with at least one jet originating from a bottom quark. For both the inclusive study and the study requiring a bottom-quark jet, the data are examined in exclusive final states corresponding to all-hadronic, single-lepton, and dilepton events. The study is based on the data set of proton-proton collisions at sqrt(s) = 7 TeV collected with the CMS detector at the LHC in 2011, corresponding to an integrated luminosity of 4.7 inverse femtobarns. The study consists of a shape analysis performed in the plane of two kinematic variables, denoted MR and R2, that correspond to the mass and transverse energy flow, respectively, of pair-produced, heavy, new-physics particles. The data are found to be compatible with the background model, defined by studying event simulations and data control samples. Exclusion limits for squark and gluino production are derived in the context of the constrained minimal supersymmetric model (CMSSM) and also for simplified-model spectra (SMS). Within the CMSSM parameter space considered, squark and gluino masses up to 1350 GeV are excluded at 95% confidence level, depending on the model parameters. For SMS scenarios, the direct production of pairs of top or bottom squarks is excluded for masses as high as 400 GeV.

description: The structure of the cold spot, of a non-Gaussian anomaly in the cosmic microwave background (CMB) sky first detected by Vielva et al. is studied using the data by Planck satellite. The obtained map of the degree of stochasticity (K-map) of CMB for the cold spot, reveals, most clearly in 100 GHz band, a shell-type structure with a center coinciding with the minima of the temperature distribution. The shell structure is non-Gaussian at a 4σconfidence level. Such behavior of the K-map supports the void nature of the cold spot. The applied method can be used for tracing voids that have no signatures in redshift surveys.

description: This paper is devoted to study the effects of electromagnetic on the collapse and expansion of anisotropic gravitating source. For this purpose, we have evaluated the generating solutions of Einstein-Maxwell field equations with spherically symmetric anisotropic gravitating source. We found that a single function generates the various anisotropic solutions. In this case every generating function involves an arbitrary function of time which can be chosen to fit several astrophysical time profiles. Two physical phenomenon occur, one is gravitational collapse and other is the cosmological expanding solution. In both cases electromagnetic field effects the anisotropy of the model. For collapse the anisotropy is increased while for expansion it deceases from maximum value to finite positive value. In case of collaps there exits two horizons like in case of Reissner-Nordstr$\ddot{o}$m metric.

description: Latent Dirichlet allocation (LDA) is a popular topic modeling technique in academia but less so in industry, especially in large-scale applications involving search engine and online advertising systems. A main underlying reason is that the topic models used have been too small in scale to be useful; for example, some of the largest LDA models reported in literature have up to $10^3$ topics, which cover difficultly the long-tail semantic word sets. In this paper, we show that the number of topics is a key factor that can significantly boost the utility of topic-modeling systems. In particular, we show that a "big" LDA model with at least $10^5$ topics inferred from $10^9$ search queries can achieve a significant improvement on industrial search engine and online advertising systems, both of which serving hundreds of millions of users. We develop a novel distributed system called Peacock to learn big LDA models from big data. The main features of Peacock include hierarchical distributed architecture, real-time prediction and topic de-duplication. We empirically demonstrate that the Peacock system is capable of providing significant benefits via highly scalable LDA topic models for several industrial applications.

Creators: name: Masiero, Federica
Publisher: name: arXiv

Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: We consider a backward stochastic differential equation in a Markovian framework for the pair of processes $(Y,Z)$, with generator with quadratic growth with respect to $Z$. Under non-degeneracy assumptions, we prove an analogue of the well-known Bismut-Elworty formula when the generator has quadratic growth with respect to $Z$. Applications to the solution of a semilinear Kolmogorov equation for the unknown $v$ with nonlinear term with quadratic growth with respect to $\nabla v$ and final condition only bounded and continuous are given, as well as applications to stochastic optimal control problems with quadratic growth.

description: We complement the Markowitz portfolio theory by adding a social dimension. Every asset is assigned a social return, which is generally modeled as stochastic. We focus on the theoretical foundation and practical implications of portfolio choice with social returns. We apply the theoretical model to two different microfinance investments. First, we consider an investor who is risk-neutral in the social dimension and faces a small number of assets: an equity index, a bond index and a microfinance investment fund (MFIF). Second, we address the question of how MFIFs should allocate funds to microfinance institutions.

description: Let $\mathbb{X}$ be a weighted projective line and $\operatorname{coh}\mathbb{X}$ the associated categoy of coherent sheaves. We classify the tilting complexes $T$ in $D^b(\operatorname{coh}\mathbb{X})$ such that $τ^2 T\cong T$, where $τ$ is the Auslander-Reiten translation in $D^b(\operatorname{coh}\mathbb{X})$. As an application of this result, we classify the 2-representation-finite algebras which are derived-equivalent to a canonical algebra. This complements Iyama-Oppermann's classification of the iterated tilted 2-representation-finite algebras. By passing to 3-preprojective algebras, we obtain a classification of the selfinjective cluster-tilted algebras of canonical-type. This complements Ringel's classification of the selfinjective cluster-tilted algebras.

description: Disformally coupled cosmologies arise from Dirac-Born-Infeld actions in Type II string theories, when matter resides on a moving hidden sector D-brane. Since such matter interacts only very weakly with the standard model particles, this scenario can provide a natural origin for the dark sector of the universe with a clear geometrical interpretation: dark energy is identified with the scalar field associated to the D-brane's position as it moves in the internal space, acting as quintessence, while dark matter is identified with the matter living on the D-brane, which can be modelled by a perfect fluid. The coupling functions are determined by the (warped) extra-dimensional geometry, and are thus constrained by the theory. The resulting cosmologies are studied using both dynamical system analysis and numerics. From the dynamical system point of view, one free parameter controls the cosmological dynamics, given by the ratio of the warp factor and the potential energy scales. The disformal coupling allows for new scaling solutions that can describe accelerating cosmologies alleviating the coincidence problem of dark energy. In addition, this scenario may ameliorate the fine-tuning problem of dark energy, whose small value may be attained dynamically, without requiring the mass of the dark energy field to be unnaturally low.

Subjects: subject: Health sciences

description: Problem: Open and responsive safeguarding communications between multiagency professionals who work with children and young people can be critical. Few studies have examined the experience of interprofessional safeguarding communications, and most reports are of social workers. This study explored safeguarding communications from the perspectives of four disciplines. Method: Semistructured interviews were conducted in (London) England with 11 professionals who were purposively sampled for their involvement in safeguarding and child protection work: school nurses (n = 4); teachers (n = 3); general practitioner (n = 1); and social workers (n = 3). Interviews were audio‐recorded, transcribed verbatim, and thematically analyzed. Findings: Five themes emerged from participant data to describe their experiences of safeguarding communications: communication technology; care coordination; professional relationships; information sharing; and, resources. Conclusions: Although participants reported positive experiences they also encountered significant communication challenges in their safeguarding roles. Complex technology could alienate as well as connect professionals, for which some IT system and process improvements were recommended. However, participants also wanted more opportunities for face‐to‐face contact. Their experiences indicate that effective safeguarding communications are best assured by both.

description: Is the brain really operating at a critical point? We study the non-equilibrium properties of a neural network which models the dynamics of the neocortex and argue for optimal quasi-critical dynamics on the Widom line where the correlation length is maximal. We simulate the network and introduce an analytical mean-field approximation, characterize the non-equilibrium phase transition, and present a non-equilibrium phase diagram, which shows that in addition to an ordered and disordered phase, the system exhibits a quasiperiodic phase corresponding to synchronous activity in simulations which may be related to the pathological synchronization associated with epilepsy.

The Cross-correlation of MgII Absorption and Galaxies in BOSS

description: We present a measurement of the cross-correlation of MgII absorption and massive galaxies, using the DR11 main galaxy sample of the Baryon Oscillation Spectroscopic Survey of SDSS-III (CMASS galaxies), and the DR7 quasar spectra of SDSS-II. The cross-correlation is measured by stacking quasar absorption spectra shifted to the redshift of galaxies that are within a certain impact parameter bin of the quasar, after dividing by a quasar continuum model. This results in an average MgII equivalent width as a function of impact parameter from a galaxy, ranging from 50 kpc to more than 10 Mpc in proper units, which includes all MgII absorbers. We show that special care needs to be taken to use an unbiased quasar continuum estimator, to avoid systematic errors in the measurement of the mean stacked MgII equivalent width. The measured cross-correlation follows the expected shape of the galaxy correlation function, although measurement errors are large. We use the cross-correlation amplitude to derive the bias factor of MgII absorbers, finding bMgII = 2.33 \pm? 0.19, where the error accounts only for the statistical uncertainty in measuring the mean equivalent width. This bias factor is larger than that obtained in previous studies and may be affected by modeling uncertainties that we discuss, but if correct it suggests that MgII absorbers at redshift z \simeq 0:5 are spatially distributed on large scales similarly to the CMASS galaxies in BOSS.

Tuning a magnetic Feshbach resonance with spatially modulated laser light

description: We theoretically investigate the control of a magnetic Feshbach resonance using a bound-to-bound molecular transition driven by spatially modulated laser light. Due to the spatially periodic coupling between the ground and excited molecular states, there exists a band structure of bound states, which can uniquely be characterized by some extra bumps in radio-frequency spectroscopy. With the increasing of coupling strength, the series of bound states will cross zero energy and directly result in a number of scattering resonances, whose position and width can be conveniently tuned by the coupling strength of the laser light and the applied magnetic field (i.e., the detuning of the ground molecular state). In the presence of the modulated laser light, universal two-body bound states near zero-energy threshold still exist. However, compared with the case without modulation, the regime for such universal states is usually small. An unified formula which embodies the influence of the modulated coupling on the resonance width is given. The spatially modulated coupling also implies a local spatially varying interaction between atoms. Our work proposes a practical way of optically controlling interatomic interactions with high spatial resolution and negligible atomic loss.

Consequences of fleet diversification in managed and unmanaged fisheries

Subjects: subject: Populations and Evolution (q-bio.PE)
subject: FOS: Biological sciences

description: Biological diversity is known to play an important role in generating and maintaining ecosystem productivity and other functions, and has consequently become a central focus of many efforts to preserve ecosystem services. Theoretical parallels suggest the diversity of fishing fleets may have a similarly important role in determining the productivity and ecological impacts of fisheries, but this possibility has rarely been explored. Here I present theoretical analyses showing that the diversity of métiers - combinations of technology, target species, and fishing grounds - and technical efficiencies in a fishing fleet have important impacts on the productivity, profitability, and ecological impacts of fisheries, particularly mixed-stock or multispecies fisheries. Diversification of métiers can increase yields and reduce threats to weak stocks in both managed and unmanaged multispecies fisheries. Diversification of technical efficiencies creates opportunities for larger profits in managed fisheries, but often decreases yields and worsens impacts on weak stocks in unmanaged fisheries. These results suggest that the potential impact of management may be highest in fisheries with diverse fleets.

title: Building Maps Based on a Learned Classification of Ultrasonic Range Data
Creators: name: Kurz, Andreas
Publisher: name: IFAC - International Federation of Automatic Control
Year: 2023

description: This paper introduces an approach for learning environmental maps based on ultrasonic range data. A neural network concept (self-organizing feature map) is used to learn a classification of the range data which makes it possible to discern situations. As a consequence the free-apace is partitioned into situation areas which are defined as regions wherein a specific situation can be recognized. Using dead-reckoning such situation areas can be attached to graph nodes generating a map of the free-space in the form of a graph representation. In this context it is discussed how the dead-reckoning drift can be compensated.
