Der DFG-geförderte Fachinformationsdienst Romanistik (FID) wird von der SUB Hamburg und der ULB Bonn betrieben und bietet laufend weiterentwickelte Services für die Bereitstellung und Recherche von Literatur für die Forschung sowie ein reichhaltiges fachspezifisches Online-Informationsangebot. Der Beitrag illustriert, wie der FID mit seinen Teilprojekten Forschungsdatenmanagement (FDM) und Open-Access-Publizieren (OA) sowie mit den neuen Kommunikationskanälen eine transdisziplinäre digitale Romanistik unterstützt. Zunächst wird argumentiert, dass FDM nach den FAIR-Prinzipien Transdisziplinarität immer schon mitdenkt. Nach einer Vorstellung der entsprechenden Unterstützungsangebote des FID wird auf die Bedeutung einer konsistenten Metadatenvergabe eingegangen und eine breitere fachinterne Diskussion zu diesem Thema angeregt. Als nächstes wird das Informationsangebot des FID zum Thema OA vorgestellt sowie ein Ausblick auf das gerade eingerichtete Repositorium für romanistische OA-Publikationen geboten, das als zentrale Anlaufstelle für frei zugängliche fachspezifische Erst- und Zweitveröffentlichungen konzipiert ist. Abschließend werden mit dem Romanistik-Blog und dem Twitter-Kanal des FID zwei Angebote präsentiert, die neben der Information über aktuelle Entwicklungen in relevanten Bereichen auch die Vernetzung innerhalb und außerhalb der Fachcommunity unterstützen.

In the ongoing decade, port logistics in Europe have been exposed to intense competition. Especially container ports experience competition not only for ships but also for supply chains. To adapt to this trend, terminal operators are improving the efficiency in port logistics through, among other things, automation of port operations. Most of these efforts concern processes handling shipped goods. Instead of concentrating on these well-researched improvements, we explored the feasibility and economic potential of an intelligent lighting control system. Often automating handling processes need high investments in hard- and software. This smart lighting system is supposed to control demand-actuated outdoor lights in a harbour environment. In this research, movement profiles of straddle carriers and infrastructural data were gathered and refined to build a model of the observed container terminal. The modelled infrastructure includes the position of every lighting tower and its illuminant as well as their specific power consumption and the respective area, which those lights illume. To control these lights, we developed a control algorithm. We investigated through simulation experiments the power savings for this autonomous lighting control system. Multiple influential factors of this control concept were evaluated by varying the parameterization of the algorithm. A gathered data set, containing trajectories of operating straddle carriers during full terminal utilization, is the basis for the mentioned experiments. The results of varying the utilization rate of the terminal have identified a relationship between capacity and percental power consumption, in the form of a root function. The more straddle carriers run, the less the overall power consumption is increasing. Using the intelligent light control system on full utilization saves 14.67% of the total energy. In the case of 80 % terminal utilization, 18.22 % of total energy is subject for saving effects. Besides these results, we were able to explore the influences of the algorithm parameterization on the energy savings and could assess these solutions economically.

Neben einer zunehmenden Attraktivitat des E-Commerce ist gleichzeitig ein steigendes Interesse an Themen der Nachhaltigkeit auf Ebene der Verbraucher zu verzeichnen, welche eine nachhaltigere Lieferung ihrer bestellten Waren wunschen. Unser Beitrag betrachtet den Trade-Off zwischen dem Bedurfnis nach mehr Nachhaltigkeit und einem durch den E-Commerce verursachten zunehmenden Lieferaufkommen. Dabei zeichnet sich insbesondere der Lebensmitteleinzelhandel durch einen wachsenden Bedarf nachhaltiger Produkte und Lieferungen aus.

Although retailers and logistics service providers offer various last mile delivery options, the level of individualisation regarding integrating consumer demands and expectations for home delivery is currently low. In order to offer such individualised delivery options, it is necessary to understand consumers' home delivery needs and wants. Accordingly, this paper examines consumer preferences regarding delivery options, focusing on online grocery retailing using a discrete choice experiment approach. Our results show that consumers can derive high benefits from the individualization of delivery options, especially in the areas of vehicle type and place of delivery. Also, packaging and delivery time are relevant delivery options for consumers but considered to be less useful than transport vehicles and place of delivery, while consumers do not prefer the selection of a time window on the day of delivery.

The online grocery trade has received an additional boost from the Covid pandemic. The delivery of such purchases places particular demands on last mile logistics since consumers demand more and more individualized delivery options, e.g., regarding the delivery arrival or the type of transport. At the same time, many consumers are becoming more environmentally conscious, so there is a need to examine further how this particular consumer behavior affects the sustainability of deliveries. This paper develops and presents a simulation model, which considers grocery delivery under different framework conditions. The examined scenarios show that a change in consumer behavior directly impacts last mile logistics systems, mainly by increasing the total number of orders and a slight reduction in emissions through improved vehicle utilization. Nevertheless, the results show that without sufficiently high utilization of delivery vehicles, shopping trips by private car may cause fewer emissions.

Privilege separation has been proposed to reduce exploitation capabilities attackers may gain after successfully infiltrating a process, e.g. a network daemon. In this article we present a highly automated approach for decomposition of existing source code in order to realize such a privilege separation for existing monolithic software. For this, we describe an approach to analyze the source code, generating necessary inter-process communication (IPC), global variable handling and a dynamic memory monitoring. To show practical suitability, the approach is evaluated by being applied to two open source network daemons.

The major cause of IT security incidents are software issues, hence this article presents an automated approach for source code partitioning and privilege separation. Based on static call graph analysis, functions and program parts of a monolithic software are separated in several processes and grouped by the privilege they need. For the partitioning we introduce a metric that estimates the potential security gain by considering the complexity and privilege distribution of the separated software. Furthermore, we present a partitioning heuristic that uses this metric to create a secure software partitioning.

A typical office worker nowadays spends the majority of his time sedentary in the course of his working life. In this paper, we address the problem of sedentariness in the context of office work through smooth integration of light physical activity into the daily work routine. Equipping a flexible office chair with motion sensing functionality, the chair becomes a ubiquitous input device that provides an office worker with the possibility to use the movements of his body for tilting, rotating, or bouncing to control his workplace computer. Based on this idea, we apply an existing gesture taxonomy to body movements on an active office chair, and explore different application scenarios for ubiquitous gestural chair interaction.

Multipath routing allows for a reliable communication in ad-hoc networks, e.g., to transport VoIP calls in disaster scenarios. Due to the usage of different paths in conjunction with Forward Error Correction, failures can be tolerated without interrupting real-time transmissions. However, current multipath algorithms either depend on global topology information, perform an excessive message flooding, or require information of physical node positions. The situation becomes even worse if efficient broadcasts are impossible, e.g., due to some point-to-point links or if authentication is required and asymmetric signatures cannot be considered. Thus, this article introduces Scalable Multipath Exploration in Ad-Hoc Networks (SMEAN) as a method to discover, estimate, and select ad-hoc multipaths. SMEAN uses an overlay structure that is embedded into the transport network to discover overlay paths that utilize highly disjoint underlay paths. The low overhead allows for a reactive usage, e.g., when a VoIP is established. A simulative evaluation shows that SMEAN is able to set up suited multipath topologies with only a fraction of the messages needed by common ad-hoc routing algorithms.

Apolipoprotein B100 (apoB100)-containing lipoproteins (very low density lipoprotein (VLDL) and low density lipoprotein (LDL)) are the principal fat and cholesterol carriers in blood. During metabolic conversion from VLDL to LDL, the particle size decreases (from ∼ 80 nm to 20 nm) and lipid composition is changed, however, the amphiphilic apoB100 molecule remains bound to its lipoprotein particle and most likely compensates for structural changes due to its inherent conformational flexibility and dynamics .Here, we report on motions in the time range of 100 ps to 1 ns in human-LDL, human VLDL and yolk-VLDL, which were recorded by elastic neutron-scattering temperature scans from 20K to 310 K using hydrated lipoprotein powders. The mean square displacement values were calculated from the scattering vector dependence of the elastic intensity I(Q). The effective force constants , which are a measure for the resilience of the particle, were derived from the slopes in the vs. T scans. In the low-temperature harmonic regime we found no substantial differences between lipoprotein fractions ( ∼1 N/m). Nevertheless, lipoproteins are softer compared to hydrated myoglobin powder (2 N/m) or purple membranes (1.7 N/m) [1]. Significant differences were observed with increasing temperatures. Both, human and yolk VLDL show two breaks in the scan with a steep increase in above 270K, whereas LDL shows a smooth behavior above a dynamic transition around 220K. Accordingly, at physiological temperatures VLDL-fractions are highly soft and mobile ( ∼0.08 N/m) as compared to LDL ( ∼ 0.2 N/m). Sucrose, added as cryoprotectant, significantly modified the dynamics of VLDL, as it confers extreme stability to VLDL over the whole temperature range and substantially suppresses dynamic transitions.[1] G.
