description: A distinguishing characteristic of wireless sensor networks is the opportunity to exploit characteristics of the application at lower layers. This paper reports on the results of a simulation comparison of proposed data dissemination protocols using the J-Sim simulator for the WSN protocols: Forwarding Diffusion Data Dissemination(FDDDP), Decentralized Data Dissemination(DDDP), Credit Broadcast Data Dissemination (CBDDP), Energy Aware & Geographical Data Dissemination (EAGDDP) .Our performance provides useful insights for the network designer such as which protocols (and design choices) scale control traffic well, improve data delivery or reduce overall energy consumption,improves routing overhead and maximizes the bandwidth utilization. The static pre configuration of the cell size in DDDP, is one of the reasons why DDDP exhibits larger routing overhead than FDDDP by 74.2% on average. Although CBDDP produces approximately 94.6% smaller overhead than DDDP and 90.7% smaller than FDDDP, because of statically configured amount credit CBDDP delivers on average 7.5 times more of the redundant data packets than DDDP and FDDDP.EAGDDP improves the delivery by 80% on average and makes a balance of energy consumption .We suggest that making these protocols truly self-learning can significantly improve their performance.

description: We analyze theoretically the many-body dynamics of a dissipative Ising model in a transverse field using a variational approach. We find that the steady-state phase diagram is substantially modified compared to its equilibrium counterpart, including the appearance of a multicritical point belonging to a different universality class. Building on our variational analysis, we establish a field-theoretical treatment corresponding to a dissipative variant of a Ginzburg-Landau theory, which allows us to compute the upper critical dimension of the system. Finally, we present a possible experimental realization of the dissipative Ising model using ultracold Rydberg gases. © 2017 American Physical Society.

description: In this paper, we apply dimensional analysis to study a diffusive molecular communication system that uses diffusing enzymes in the propagation environment to mitigate intersymbol interference. The enzymes bind to information molecules and then degrade them so that they cannot interfere with the detection of future transmissions at the receiver. We determine when it is accurate to assume that the concentration of information molecules throughout the receiver is constant and equal to that expected at the center of the receiver. We show that a lower bound on the expected number of molecules observed at the receiver can be arbitrarily scaled over the environmental parameters, and generalize how the accuracy of the lower bound is qualitatively impacted by those parameters.

description: We show that strongly interacting multicomponent gases in one dimension realize an effective spin chain, offering an alternative simple scenario for the study of one-dimensional (1D) quantum magnetism in cold gases in the absence of an optical lattice. The spin-chain model allows for an intuitive understanding of recent experiments and for a simple calculation of relevant observables. We analyze the adiabatic preparation of antiferromagnetic and ferromagnetic ground states, and show that many-body spin states may be efficiently probed in tunneling experiments. The spin-chain model is valid for more than two components, opening the possibility of realizing SU(N) quantum magnetism in strongly interacting 1D alkaline-earth-metal or ytterbium Fermi gases. © 2014 American Physical Society.

description: Raman-assisted hopping may be used to realize the anyon Hubbard model in one-dimensional optical lattices. We propose a feasible scenario that significantly improves the proposal of T. Keilmann et al. [Nat. Commun. 2, 361 (2011)], allowing as well for an exact realization of the two-body hard-core constraint, and for controllable effective interactions without the need of Feshbach resonances. We show that the combination of anyonic statistics and two-body hard-core constraint leads to a rich ground-state physics, including Mott insulators with attractive interactions, pair superfluids, dimer phases, and multicritical points. Moreover, the anyonic statistics results in a novel two-component superfluid of holon and doublon dimers, characterized by a large but finite compressibility and a multipeaked momentum distribution, which may be easily revealed experimentally. © 2015 American Physical Society.
On the origin of orbital period change in WY Cancri: a genuine angular momentum loss?
Creators: name: Chen, Wen-Cong
Publisher: name: arXiv
Year: 2013
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: WY Cancri is a short-period ($P$=0.829 d) eclipsing RS Canum Venaticorum stars, and both components are late-type stars. Recently, observations provided by photometric observations and light time minima show that the orbital period of WY Cancri is experiencing a secular decrease at a rate of ${\rm d} P/{\rm d}t=-1.2\times10^{-7}\rm d yr^{-1}$. In this Letter, we attempt to investigate if the period change of WY Cancri can originate from the angular momentum loss. In calculation, we assume that this source has a high wind loss rate of $\sim10^{-10} \rm M_{\odot} yr^{-1}$. To account for the observation, magnetic braking demands a strong surface magnetic field of $\gtrsim 10000$ G like Ap/Bp stars. Furthermore, if this source may be surrounded by a circumbinary disk, and 6% of the wind loss feeds the disk, tidal torque between the disk and the binary can offer the observed angular momentum loss rate. Such a strong magnetic field or an extremely high wind input fraction seem to be highly unlikely.

description: Non-selective luminescence spectroscopy and luminescence line-narrowing spectroscopy were used to study the retention of UO22+ on titanium dioxide (TiO2), synthetic calcium silicate hydrate (C-S-H) phases and hardened cement paste (HCP). Non-selective luminescence spectra showed strong inhomogeneous line broadening resulting from a strongly disordered UO22+ bonding environment. This problem was largely overcome by using luminescence line-narrowing spectroscopy. This technique allowed unambiguous identification of three different types of UO22+ sorbed species on C-S-H phases and HCP. Comparison with spectra of UO22+ sorbed onto TiO2 further allowed these species to be assigned to a surface complex, an incorporated species and an uranate-like surface precipitate. This information provides the basis for mechanistic models describing the UO22+ sorption onto C-S-H phases and HCP and the assessment of the mobility of this radionuclide in a deep geological repository for low and intermediate level radioactive waste (L/ILW) as this kind of waste is often solidified with cement prior to storage.

description: Starting from the fusion rules for the algebra SO(5)2we construct one-dimensional lattice models of interacting anyons with commuting transfer matrices of ‘interactions round the face’ (IRF) type. The con-served topological charges of the anyon chain are recovered from the transfer matrices in the limit of large spectral parameter. The properties of the models in the thermodynamic limit and the low energy excitations are studied using Bethe ansatz methods. Two of the anyon models are critical at zero temperature. From the analysis of the finite size spectrum we find that they are effectively described by rational conformal field theories invariant under extensions of the Virasoro algebra, namely WB2and WD5, respectively. The latter contains primaries with half and quarter spin. The modular partition function and fusion rules are derived and found to be consistent with the results for the lattice model.

description: Complex I has a unique structure in plants and includes extra subunits. Here, we present a novel study to define its protein constituents. Mitochondria were isolated from Arabidopsis thaliana cell cultures, leaves, and roots. Subunits of complex I were resolved by 3D blue-native (BN)/SDS/SDS-PAGE and identified by mass spectrometry. Overall, 55 distinct proteins were found, seven of which occur in pairs of isoforms. We present evidence that Arabidopsis complex I consists of 49 distinct types of subunits, 40 of which represent homologs of bovine complex I. The nine other subunits represent special proteins absent in the animal linage of eukaryotes, most prominently a group of subunits related to bacterial gamma-type carbonic anhydrases. A GelMap http://www.gelmap.de/arabidopsis-3d-complex-i/ is presented for promoting future complex I research in Arabidopsis thaliana.

description: SBR759 is a novel polynuclear iron(III) oxide–hydroxide starch·sucrose·carbonate complex being developed for oral use in chronic kidney disease (CKD) patients with hyperphosphatemia on hemodialysis. SBR759 binds inorganic phosphate released by food uptake and digestion in the gastro-intestinal tract increasing the fecal excretion of phosphate with concomitant reduction of serum phosphate concentrations. Considering the high content of ∼20% w/w covalently bound iron in SBR759 and expected chronic administration to patients, absorption of small amounts of iron released from the drug substance could result in potential iron overload and toxicity. In a mechanistic iron uptake study, 12 healthy male subjects (receiving comparable low phosphorus-containing meal typical for CKD patients: ≤1000 mg phosphate per day) were treated with 12 g (divided in 3 × 4 g) of stable 58Fe isotope-labeled SBR759. The ferrokinetics of [58Fe]SBR759-related total iron was followed in blood (over 3 weeks) and in plasma (over 26 hours) by analyzing with high precision the isotope ratios of the natural iron isotopes 58Fe, 57Fe, 56Fe and 54Fe by multi-collector inductively coupled mass spectrometry (MC-ICP-MS). Three weeks following dosing, the subjects cumulatively absorbed on average 7.8 ± 3.2 mg (3.8–13.9 mg) iron corresponding to 0.30 ± 0.12% (0.15–0.54%) SBR759-related iron which amounts to approx. 5-fold the basal daily iron absorption of 1–2 mg in humans. SBR759 was well-tolerated and there was no serious adverse event and no clinically significant changes in the iron indices hemoglobin, hematocrit, ferritin concentration and transferrin saturation.

description: In this paper we investigate the spin currents and the von Neumann entropy (VNE) of an Heisenberg XXZ chain in contact with twisted XY-boundary magnetic reservoirs by means of the Lindblad master equation. Exact solutions for the stationary reduced density matrix are explicitly constructed for chains of small sizes by using a quantum symmetry operation of the system. These solutions are then used to investigate the optimal transport in the chain in terms of the VNE. As a result we show that the maximal spin current always occurs in the proximity of extrema of the VNE and for particular choices of parameters (coupling with reservoirs and anisotropy) it can exactly coincide with them. In the limit of strong coupling we show that minima of the VNE tend to zero, meaning that the maximal transport is achieved in this case with states that are very close to pure states.

description: We report a combined theoretical and microwave spectroscopy study of the internal dynamics of the benzene dimer, a benchmark system for dispersion forces. Although the extensive ab initio calculations and experimental work on the equilibrium geometry of this dimer have converged to a tilted T-shaped structure, the rich internal dynamics due to low barriers for internal rotation have remained largely unexplored. We present new microwave spectroscopy data for both the normal (C6H6)(2) and partially deuterated (C6D6)(C6H6) dimers. The splitting patterns obtained for both species are unraveled and understood using a reduced-dimensionality theoretical approach. The hindered sixfold rotation of the stem can explain the observed characteristic 1 : 2 : 1 tunneling splitting pattern, but only the concerted stem rotation and tilt tunneling motion, accompanied by overall rotation of the dimer, yield the correct magnitude of the splittings and their strong dependence on the dimer angular momentum J that is essential to explain the experimental data. Also the surprising observation that the splittings are reduced by 30% for the mixed (C6D6)(C)(C6H6)(S) dimer in which only the cap (C) in the T-shaped structure is deuterated, while the rotating stem (S) monomer is the same as in the homodimer, is understood using this approach. Stark shift measurements allowed us to determine the dipole moment of the benzene dimer, mu = 0.58 +/- 0.051 D. The assumption that this dipole moment is the vector sum of the dipole moments induced in the monomers by the electric field of the quadrupole on the other monomer yields a calculated value of mu = 0.63 D. Furthermore, the observed Stark behavior is typical for a symmetric top, another confirmation of our analysis.
Harnack type inequality for positive solution of some integral equation

Publisher: name: arXiv
Year: 2013
Subjects: subject: Analysis of PDEs (math.AP)
subject: FOS: Mathematics

description: In this paper, we establish some Harnack type inequalities satisfied by positive solutions of nonlocal inhomogeneous equations arising in the description of various phenomena ranging from population dynamics to micro-magnetism. For regular domains, we also derive an inequality up to the boundary. The main difficulty in such context lies in a precise control of the solutions outside a compact set and the existence of local uniform estimates. We overcome this problem by proving a contraction result which makes the $L^1$ norms of the solutions on two compact sets $ø_1\subset\subsetø_2$ equivalent. We also construct the principal positive eigenfunctions associated to particular nonlocal operators by using the corresponding Harnack type inequalities.

description: Double electron electron resonance spectroscopy is a versatile and powerful tool for probing paramagnetic systems such metalloproteins and proteins with conjugated spin labels. Chapter 1 introduces EPR theory and the molecular biological concepts that this work is based on. This lays the groundwork with regard to basic knowledge and principles that the following chapters rely on. Chapter 2 collates the methodology used in all aspects of the work conducted in this body of work so that the techniques used may be critically assessed and the work reproduced under the same conditions in future experimentation. Chapter 3 focuses on the in-silico investigation of human calmodulin1 and applies a combinatorial approach utilising bioinformatic and computational techniques towards site selection for site-directed spin labelling and the elucidation of calmodulin1 conformational states through production of simulated models and predictions for expected DEER distance distributions. This ranges from literature reviews, structural region identification and degree of conservation assessment through to AI generated predicted models for secondary and tertiary structures and spin label modelling across different predicted conformational states and predicted distances. Chapter 4 provides a detailed explanation of the experimental work conducted to produce the variants of interest and the subsequent in-vitro process of data acquisition with details on a case-by-case basis. This focuses on the interactions between calmodulin1, Ca²⁺ and the M13 peptide. Chapter 5 takes a look at a comparative labelling technique that takes advantage of a rigid diHis motif for Cu²⁺ spin labelling in combination with MTSL (R1 when peptide-conjugated) for Cu²⁺NTA-R1 measurements that have been previously conducted in chapter 4 and utilises a different technique for distance measurements, RIDME. This chapter also applies other applications of RIDME to different spin systems, this time measuring distances between HisTag-bound Mn²⁺ and R1, taking advantage of another type of spin labelling technique.

description: We present the results on the study of the global and local M-Z relation based on the first data available from the CALIFA survey (150 galaxies). This survey provides integral field spectroscopy of the complete optical extent of each galaxy (up to 2-3 effective radii), with enough resolution to separate individual HII regions and/or aggregations. Nearly $\sim$3000 individual HII regions have been detected. The spectra cover the wavelength range between [OII]3727 and [SII]6731, with a sufficient signal-to-noise to derive the oxygen abundance and star-formation rate associated with each region. In addition, we have computed the integrated and spatially resolved stellar masses (and surface densities), based on SDSS photometric data. We explore the relations between the stellar mass, oxygen abundance and star-formation rate using this dataset. We derive a tight relation between the integrated stellar mass and the gas-phase abundance, with a dispersion smaller than the one already reported in the literature ($σ_{Δ{\rm log(O/H)}}=$0.07 dex). Indeed, this dispersion is only slightly larger than the typical error derived for our oxygen abundances. However, we do not find any secondary relation with the star-formation rate, other than the one induced due to the primary relation of this quantity with the stellar mass. We confirm the result using the $\sim$3000 individual HII regions, for the corresponding local relations. Our results agree with the scenario in which gas recycling in galaxies, both locally and globally, is much faster than other typical timescales, like that of gas accretion by inflow and/or metal loss due to outflows. In essence, late-type/disk dominated galaxies seem to be in a quasi-steady situation, with a behavior similar to the one expected from an instantaneous recycling/closed-box model.

description: The BioDT project took part in the workshop "Assessing and Preserving Soundscapes in National Parks" held on a sunny Sunday, May 28th, 2023, at the Braemar Village Hall in the Cairngorms National Park, Scotland. This workshop shed light on the significant role of the UK-SCAPE long-term environment monitoring conducted at the ECN site and its connection to groundbreaking research aiming to create a digital twin that would link the park's recreational potential with its biodiversity. Jan Dick (UK Centre for Ecology and Hydrology), alongside Tin Oberman from the Institute for Environmental Design and Engineering at The Bartlett, University College London (UCL), and Simone Torresin from the Department of Civil, Environmental and Mechanical Engineering at the Università degli Studi di Trento, captivated an audience of approximately 25 young acousticians, sound artists, engineers, and both academic and professional individuals. Notably, members of the Cairngorms National Park authority were also in attendance. Throughout the 1.5-hour workshop, participants delved into the significance of preserving and appreciating soundscapes, exploring the science behind human perception of soundscapes using ISO standards, incorporating long-term standard monitoring observations from the eLTER program, and recognizing the value of soundscapes in the context of tourism. The workshop provided a unique opportunity to highlight the intersection of the BioDT project's objectives with the broader field of sound preservation and its implications for national parks.

description: Die Einführung elektronischer Akten in Verwaltungen hat sich trotz gesetzlicher Vorgaben und technischer Machbarkeit als herausfordernd erwiesen. Diese Studie untersucht die Einführung der eAkte in fünf niedersächsischen Verwaltungen und identifiziert Herausforderungen sowie Erfolgsfaktoren für Implementierungsprojekte. Durch sechs Interviews mit sieben Experten aus der Verwaltung wurde eine interne Perspektive auf die Projekte gewonnen. Die Ergebnisse zeigen, dass organisatorische und soziale Herausforderungen die Einführungsprojekte häufig beeinträchtigten, während technische Aspekte weniger bedeutend waren. Die transparente Kommunikation, die Beteiligung aller Mitarbeiter und gezielte Schulungen wurden als entscheidend betrachtet, um die Akzeptanz und Nutzung der eAkte zu fördern. Auch die Rolle der Führungskräfte erwies sich als entscheidend für den Projekterfolg. Diese Erkenntnisse verdeutlichen den herausfordernden Übergang von der papierbasierten zur digitalen Verwaltung. Es besteht die Chance, dass durch die erfolgreiche Überwindung der organisatorischen Trägheit durch die Digitisierung die nachfolgende Digitalisierung von Prozessen und Transformation von Arbeitsweisen schneller stattfindet.

description: Fire brigade operations centers and public safety answering points are important actors in fire and civil protection. Part of their work, as an emergency response service, is the creation, management and evaluation of mission reports along rescue events. While the coordination of these parties in joint missions is of utmost importance, the detailed reporting of the rescue events is likewise mandatory and necessary to keep track of the happenings and resources on site as well as to maintain traceability. In Germany, on the federal state level, common standards and harmonized terminology regarding data on the management, coordination and format of resources used in civil protection are still lacking. Some federal states, administrative districts have even established their own workflows and formats for mission reports, hampering interoperability and making aggregation of data and statistics on missions of actors in fire and civil protection cumbersome and costly. To overcome these challenges, we develop a concept for a common format and handling of mission reports for the federal state Rhineland-Palatinate and their automatic integration into the central data portal BKS-Portal.rlp. Desk research and interviews are used to gather requirements, followed by developing a prototype using SCRUM.

description: We report on the photoluminescence (PL) properties of MgZnO/ZnO heterojunctions grown by plasma-assisted molecular-beam epitaxy. Influence of the applied magnetic field (B) on the radiative recombination of the two-dimensional electron gas (2DEG) is investigated up to 54 T. An increase in magnetic field in the range of B <= 20 T results in a redshift in the PL. Abrupt lineshape changes in the PL spectra are observed at higher magnetic fields, in correlation with the integer quantum Hall states. We attempt to interpret these features using the conventional model for the 2DEG-related PL based on the transition between the 2DEG and a hole as well as a model taking a bound state effect into account, i.e., a charged exciton. The comparison about the adequateness of these models was made, being in favor of the charged exciton model.

description: The current paper presents a work-in-progress study extending previous research on technology resistance among public sector employees by introducing a social environment approach, providing a more inclusive view of resistance towards technology in the public sector. We argue that technology-resisting behavior at the individual level may be modified by both individual characteristics, such as the susceptibility to the status quo bias, as suggested by previous work, and the particular social environment. We argue that the unique organizational-cultural characteristics of the public sector constitute a special social environment that may induce job-related technology resistance among public sector employees. We expect this effect to be moderated by generational cohorts and the progress in digitalization of the respective employing public administration. To test our hypotheses, we propose an online experiment to explore the relationship between public sector employees’ attitudes towards the use of innovative technologies and the social environment.

description: Das Working Paper untersucht die Entscheidungslogiken der Softwarenutzung in Kommunalbehörden. Im Mittelpunkt stehen drei Forschungsfragen, die mit qualitativen und quantitativen Methoden untersucht werden: Erstens wird erhoben, ob Behörden in der Kommunalverwaltung eher Standard- oder Individualsoftware erwerben und wie sie diese beschaffen. Zweitens wird untersucht, ob die Software den funktionalen Anforderungen in Kommunalbehörden entspricht. Drittens werden die Ergebnisse dahingehend analysiert, wie zufrieden Nutzer mit den eingesetzten Softwareproduktenim beruflichen Alltag sind. In den Ergebnissen zeigt sich, dass Behörden der Kommunalverwaltung nicht die funktional tauglichsten Lösungen auswählen, die im Customizing an ihre spezifischen Bedarfe angepasst werden. Vielmehr wählen sie Standardprodukte aus, die sie über kommunale IT-Dienstleister einkaufen. Oftmals entfällt eine Anpassung auf den spezifischen Kontext der Behörde (Customizing). Nutzer finden insofern keine Systemlandschaft mit integrierten Fachverfahren vor. Fachverfahren mit jeweils eigenen Workflows und separaten, nicht-integrierten Datenbeständen prägen den Arbeitsalltag. Trotz dieser Befunde sind Nutzer mit der eingesetzten Software relativ zufrieden.

description: The transfer of innovations into the parent company is one of the major challenges that separate innovation paths, such as corporate incubators, are facing these days. So far there is no specific design model for the transfer of innovation from corporate incubators. This research paper therefore focusses on the development of requirements for the configuration of the interfaces between these two entities. Based on an intensive literature study as well as interviews within a German automotive supplier, requirements for the transfer process between corporate incubator and its parent company are derived and discussed.

description: Die vorliegende Arbeit präsentiert das Konzept eines innovativen Ansatzes im Bereich der digitalen Bildung. Es wird das Modul „Digitales Arbeiten“ des dualen Studiengangs Verwaltungsinformatik am Fachbereich Finanzen der Hochschule des Bundes für öffentliche Verwaltung vorgestellt. Das Modul vermittelt den Studierenden Kenntnisse und Fähigkeiten im Umgang mit digitalen Werkzeugen und Prozessen, die für eine Bewältigung des digitalen Arbeitsalltags in der öffentlichen Verwaltung erforderlich sind. Es ist inhaltlich und methodisch auf die aktuellen Anforderungen der Verwaltungsdigitalisierung abgestimmt und orientiert sich am Europäischen Rahmenwerk für Digitale Kompetenzen (DigComp). Mit diesem Konzept wird ein praxisnaher Ansatz verfolgt, der es den Studierenden ermöglicht, die erworbenen Fähigkeiten unmittelbar in realen Szenarien sowie dem behördlichen Arbeitsalltag anzuwenden. Die Teile des Moduls erstrecken sich über vier Semester und kombinieren Präsenzlehre mit digitalen Selbstlerneinheiten. Zudem werden sie durch formative Assessments begleitet, um den Wissensstand der Studierenden zu erfassen und individuelle Lernpfade zu gestalten.

description: Many spectrum methods have been proposed to use spectrum effectively, the opportunistic spectrum access has become the most viable approach to achieve near-optimal spectrum utilization by allowing secondary users to sense and access available spectrum opportunistically. However, a naive spectrum access for secondary users can make spectrum utilization inefficient and increase interference to adjacent users. In this paper, we propose a novel approach using Fuzzy Logic System (FLS) to control the spectrum access. We have to minimize the call blocking and interference. The linguistic knowledge of spectrum access are based on three descriptors namely spectrum utilization efficiency of the secondary user, its degree of mobility, and its distance to the primary user. The spectrum is chosen for accessing based on the maximum possibility for better utilization of the spectrum

description: Produzierende Unternehmen sind aufgrund der zunehmenden Bedeutung von Industrie 4.0 mit großen technologischen Veränderungen konfrontiert. Diese Veränderungen beeinflussen den gesamten Wettbewerb. Volatile Märkte, die Fokussierung auf Kundenwünsche sowie die Reduzierung der Fertigungstiefe zwingen Unternehmen ihre Prozesse kontinuierlich anzupassen, um sich klar gegenüber den Wettbewerbern im Markt zu positionieren. Die Digitalisierung in allen Unternehmensbereichen ist ein entscheidendes Mittel für Unternehmen, um unter solch schwierigen Bedingungen langfristig erfolgreich am Markt agieren zu können. Besonders kleine und mittlere Unternehmen (KMU) haben durch ihre limitierten Möglichkeiten Schwierigkeiten, den digitalen Wandel ganzheitlich im Unternehmen voranzutreiben. Mittels einer internetbasierten Plattform können dem Nutzer niedrigschwellig Informationen und Erläuterungen zu Maßnahmen für eine individuelle und zukunftsorientierte Ausrichtung der Geschäftsprozesse bereitgestellt werden. Entscheidend ist hier insbesondere die didaktische Aufbereitung der Plattforminhalte, sodass dessen Nutzung mit keinem großen Aufwand verbunden ist und gleichzeitig vom Nutzer keine besondere Expertise verlangt wird. Dieser Artikel gibt eine kurze Zusammenfassung über die entwickelten Inhalte einer solchen Projektplattform mit dem Namen ‚Industrie 4.0-Projektplattform zur Einführung für KMU (I4PE)‘. Basierend auf dem wissenschaftlichen Ansatz wird zudem eine Methodik vorgestellt, mit der die Digitalisierungsmaßnahmen dem jeweiligen Entwicklungsstand und den strategischen Entwicklungszielen eines Unternehmens zugewiesen werden.
