To mitigate the high latencies of geostationary satellite networks, TCP-splitting Performance Enhancing Proxies are deployed. However, these cannot be applied in the case of encrypted transport headers as it is the case for VPNs or QUIC. We summarize performance evaluation results from multiple measurement campaigns. In a recently concluded project, multipath communication was used to combine the advantages of very heterogeneous communication paths: low data rate, low latency (e.g., DSL light) and high data rate, high latency (e.g., geostationary satellite).

Damit einher geht eine erhöhte Komplexität beim Lebensmitteleinkauf und ein verändertes Wissen von Konsument*innen, über die Waren: Das eigene Erfahren der Lebensmittelproduktion ist im Alltag heute nicht mehr möglich. Statt praktischem Wissen gewinnt damit explizites und objektiviertes Wissen über die Waren, z.B. in Form von Siegeln an Bedeutung. Viele Produkt- und Produktionseigenschaften entziehen sich zudem der Kenntnis der Konsument*innen, während gleichzeitig das Bewusstsein für Fragen sozialer und ökologischer Nachhaltigkeit steigt. Die vorliegende Studie geht vor diesem Hintergrund am Beispiel des Einkaufs von frischem Obst und Gemüse der Frage nach, welche Bedeutung die Herkunftsangabe als Hinweis auf die Geographien der Waren für die Bewertung von frischem Obst und Gemüse hat und welches Wissen Konsument*innen über Waren und deren Biographien haben. Es wird zudem aufgezeigt, welche Rolle Nichtwissen beim Lebensmittelkonsum spielt. Die Studie liefert Erkenntnisse für die bislang im deutschsprachigen Raum noch vergleichsweise wenig repräsentierte Konsumgeographie und macht Konzepte aus der Wissens- und Organisationssoziologie für die wirtschaftsgeographische Forschung fruchtbar. Aus einer Praxisperspektive bietet sie Anschlusspunkte für Fragen des nachhaltigen Konsums sowie des Verbraucherschutzes.

Stateof- the art techniques provide exact methods for the calculation of object-specific hit probabilities given entire cache hierarchies with random inter-cache network delays. The system hit probability is a provider-centric metric as it relates to the origin offload, i.e., the decrease in the number of requests that are served by the content origin server. In this paper we consider a user-centric metric, i.e., the response time, which is shown to be structurally different from the system hit probability. Equipped with the state-of-theart exact modeling technique using Markov-arrival processes we derive expressions for the expected object response time and pave a way for its optimization under network delays.

Indeed, distributing packets over multiple networks can lead to increased robustness, resiliency and capacity. A key part of such a framework is the multi-access proxy, which transparently distributes packets over multiple paths. As the proxy needs to serve thousands of customers, scalability and performance are crucial for operator deployments. In this paper, we leverage recent advancements in data plane programming, implement a multi-access proxy based on the MP-DCCP tunneling approach in P4 and hardware accelerate it by deploying the pipeline on a smartNIC. This is challenging due to the complex scheduling and congestion control operations involved. We present our pipeline and data structures design for congestion control and packet scheduling state management. Initial measurements in our testbed show that packet latency is in the range of 25 μs demonstrating the feasibility of our approach.

More specifically, the new normal might encompass online education we are getting used to during the pandemic and the age-old onsite education as well. Thoughtfully integrated, online and onsite learning combine to create blended learning. However, the pertinent literature reveals that English as a foreign language (EFL) students and teachers differently perceive and react to blended learning in diverse contexts. This study was designed to explore student and teacher perceptions of and reactions to blended learning in the Department of English, Jahangirnagar University in the new normal. Fifty undergraduates of EFL and eight teachers of the department participated in the study. To collect data from them, the Student Questionnaire and the Teacher Questionnaire were used. And the data were processed by applying the SPSS programme module. The findings revealed that the majority of the students and the teachers had mostly positive perceptions of blended learning, although the former did not have sufficient exposure to online learning and the latter lacked adequate insights into online teaching. Further, both the students and the teachers expressed mostly positive reactions to blended learning in the new normal, though the former deemed online examinations inadequately smooth and reliable, and the latter had insufficient experience of online instruction and assessment. The study categorically recommends reforming the curriculum, adopting relevant instructional strategies, developing suitable materials, customizing the assessment, integrating and installing technology, training the teachers, upskilling the students for blended learning, improving the infrastructure, and adjusting the management.

Eine Analyse der deutschen Schuhbranche vom Hersteller bis zum Konsumenten T1 - Restructuring of value chains in digitalization. An analysis of the German footwear sector from manufacturer to consumer N2 - Globale Wertschöpfungsketten stellen nicht nur hochkomplexe Beziehungsgefüge dar, sondern unterliegen auch einem ständigen Wandlungsprozess. Ein zentraler Treiber dieser Wandlungsprozesse ist der technologische Fortschritt. Moderne Informations- und Kommunikationstechnologien, insbesondere die Phänomene der Digitalisierung und des Online-Handels, sind derzeit von besonderer Bedeutung für Wertschöpfungsketten, da unterschiedliche Fortschritte in der Digitalisierung nicht nur zu wirtschaftlichen Vor- und Nachteilen von Unternehmen führen können, sondern auch zu Up- bzw. Downgradingprozessen innerhalb der Wertschöpfungsketten. In der vorliegenden Studie wird der Fokus auf den handels- bzw. konsumentennahen Teil von Wertschöpfungsketten gelegt, um die Folgen der Digitalisierung für Hersteller, Händler und Konsumenten näher zu betrachten. Als konkretes Forschungsbeispiel dient die deutsche Schuhbranche, da sich diese gegenwärtig – von Industrie bis Handel – in einem umfassenden Strukturwandel befindet. Die Analyse zeigt, dass sich die Komplexität von Wertschöpfungsketten im Zuge der Digitalisierung deutlich erhöht (hat). In der Schuhbranche drängen neue Akteure auf den Markt, bestehende Akteure müssen sich anpassen. Direkte Folgen sind nicht nur eine neue Akteurskonstellation, sondern auch ein sich neu bildendes Machtgefüge. Es kommt somit zur Restrukturierung bisheriger Wertschöpfungsketten. N2 - Global value chains (GVC) not only represent highly complex structures of relationships, but are also subject to a constant process of change. A key driver of these processes of change is technological progress. Modern information and communication technologies, especially the phenomena of digitalization and e-commerce, are currently of particular importance for GVC, as different advances in digitalization can lead not only to economic advantages and disadvantages for companies, but also to up- or downgrading processes within GVC. This study examines on the retail- and consumer-related part of GVC in order to investigate the consequences of digitalization for manufacturers, retailers and consumers. The German footwear sector serves as a specific research example, as it is currently undergoing major structural change – from industry to retail. The analysis shows that the complexity of GVC has increased significantly in the course of digitalization. In the footwear sector, new players are entering the market and existing players have to adapt. Direct consequences are not only a new constellation of players, but also a newly forming power structure. This results in the re-organization of previous value chains.

T1 - Virtual Queues for QoS Compliance of Haptic Data Streams in Teleoperation T2 - Würzburg Workshop on Next-Generation Communication Networks (WueWoWas'22) N2 - Tactile Internet aims at allowing perceived real-time interactions between humans and machines. This requires satisfying a stringent latency requirement of haptic data streams whose data rates vary drastically as the results of perceptual codecs. This introduces a complex problem for the underlying network infrastructure to fulfill the pre-defined level of Quality of Service (QoS). However, novel networking hardware with data plane programming capability allows processing packets differently and opens up a new opportunity. For example, a dynamic and network-aware resource management strategy can help satisfy the QoS requirements of different priority flows without wasting precious bandwidth. This paper introduces virtual queues for service differentiation between different types of traffic streams, leveraging protocol independent switch architecture (PISA). We propose coordinating the management of all the queues and dynamically adapting their sizes to minimize packet loss and delay due to network congestion and ensure QoS compliance.

Bush Jr. T2 - Studies in Modern English N2 - This research paper concentrates on the analysis of the aphoristic potential of G. W. Bush’s presidential rhetoric. Aphorisms are the most ancient laconic forms of expressing original and completed thoughts which reveal the peculiarity of their authors’ world perception and worldview. From this perspective, these units can serve as the means of values codification. Repeatability and widespread use of aphorisms in various communications contribute to transmitting the values and ideas between the generations. Political aphorisms, which are a combination of aphoristic expressions from political communication and discourse, play an important role in this process. The authors of these expressions are not only politicians, but also philosophers, historians, writers, celebrities of different nationalities and generations. Presidential rhetoric is an integral and significant part of political discourse. The use of aphorisms as the means of codification of national and common human values in President G. W. Bush’s formal addresses and speeches is intentional. It makes them concise and original, influential and convincing. Aphoristic expressions denoting common human values show the ideas and beliefs of their authors, as well as the politician, about life, justice, equality, freedom, faith, family. Aphorisms defining national values become the means of updating concepts of democracy, unity and diversity, freedom and security, success, and opportunity to fulfill one’s potential in American society. The distinctive feature of G.W. Bush’s rhetoric is the frequent use of aphorisms whose authors are the Founding Fathers.

In using the strategy, research found that poor students or low proficiency learners struggled in their attempts to use it. Mainly, it was reported that it was due to their vocabulary knowledge was limited. In another aspect, retaining vocabulary learnt is also important. Such is essential since learning vocabulary does not mean knowing the definition only. Yet, learners must also be able to use the vocabulary as they engage in language skills such as reading, writing, speaking and listening. The study aims at finding the hindrances faced among poor students’ using contextual clues in retaining vocabulary. The study employed a case study to collect data from two basic students studying at a tertiary level. The study found that their hindrances in guessing meaning contexts were due to their being confused in guessing meaning when reading a sentence. Also, it was found that they were not able to find clues since they lacked vocabulary to guess correctly. The study implied that guessing meaning from context required sizeable vocabulary knowledge. Therefore, more training is necessary to assist basic learners in being successful in guessing from contexts.

The problem of the connection between language and culture has occupied the minds of many famous scientists: some believe that language is a part of the culture as a whole; others think that language is only a form of cultural expression. Undoubtedly, language constitutes a vital component of the cultural background underlying social development. Language is an essential means of communication and interaction. However, language is at the same time sovereign about culture as a whole and can be separate from culture or compared to culture as an equal element (i.e., that language is neither a form nor a component of culture).

No language in the world can remain the same after interacting with other languages. The present chapter intends to propose and support the idea of using ‘Zambian English’ for both formal and informal business. Such a measure would create the communicative competence that the majority of the Zambians have always longed for. In Zambia, the purpose of using English language office is to deliberate day to day’s business. On the contrary, this has been found to be an obstacle to those who lack principles of command in the language usage, but are able to construct sentences for communicative purposes yet are deprived in international interactions. The views expressed in this chapter are those of the language experts who were engaged in a conver� sation with regard to the possibility of creating what would be known as Zambian English (ZamEnglish).

Such resource reservations for data flows are usually established at the startup time of an application and remain untouched until the flow ends. There is no way to migrate existing flows easily to alternative paths without inducing additional delay or wasting resources. Therefore, some of the new flows cannot be embedded due to capacity limitations on certain links which leads to sub-optimal flow assignment. As future networks will need to support a large number of lowlatency flows, accommodating new flows at runtime and adapting existing flows accordingly becomes a challenging problem. In this extended abstract we summarize a previously published paper of us [1]. We combine software-defined networking (SDN), which provides better control of network flows, with TSN to be able to seamlessly migrate time-sensitive flows. For that, we formulate an optimization problem and propose different dynamic path configuration strategies under deterministic communication requirements. Our simulation results indicate that regularly reconfiguring the flow assignments can improve the latency of time-sensitive flows and can increase the number of flows embedded in the network around 4% in worst-case scenarios while still satisfying individual flow deadlines.

The design of an efficient, virtualized, context-aware, self-configuring orchestration system of a fog computing system constitutes a major development effort within this very innovative area of research. In this paper we describe the architecture and relevant implementation aspects of a cloudless resource monitoring system interworking with an SDN/NFV infrastructure. It realizes the basic monitoring component of the fundamental MAPE-K principles employed in autonomic computing. Here we present the hierarchical layering and functionality within the underlying fog nodes to generate a working prototype of an intelligent, self-managed orchestrator for advanced IoT applications and services. The latter system has the capability to monitor automatically various performance aspects of the resource allocation among multiple hosts of a fog computing system interconnected by SDN.

T1 - Towards Stateless Core Networks: Measuring State Access Patterns T2 - Würzburg Workshop on Next-Generation Communication Networks (WueWoWas'22) N2 - Future mobile communication networks, such as 5G and beyond, can benefit from Virtualized Network Functions (VNFs) when deployed on cloud infrastructures to achieve elasticity and scalability. However, new challenges arise as to managing states of Network Functions (NFs). Especially control plane VNFs, which are mainly found in cellular core networks like the 5G Core (5GC), received little attention since the shift towards virtualizing NFs. Most existing solutions for these core networks are often complex, intrusive, and are seldom compliant with the standard. With the emergence of 5G campus networks, UEs will be mainly machine-type devices. These devices communicate more deterministically, bringing new opportunities for elaborated state management. This work presents an emulation environment to perform rigorous measurements on state access patterns. The emulation comes with a fully parameterized Markov model for the UE to examine a wide variety of different devices. These measurements can then be used as a solid base for designing an efficient, simple, and standard conform state management solution that brings us further towards stateless core networks.

In this work, we propose a novel approach toward reproducible research—a structured experimental workflow that allows the creation of reproducible experiments without requiring additional efforts of the researcher. Moreover, we present our own testbed and toolchain, namely, plain orchestrating service (pos), which enables the creation of such experimental workflows. The experiment is documented by our proposed, fully scripted experiment structure. In addition, pos provides scripts enabling the automation of the bundling and release of all experimental artifacts.

This is good for the normal transmission of data in a wired or wireless system. For industrial automation and control, rather short packages are used due to the short-latency requirements. Using Shannon’s formula leads in this case to inaccurate RRM solutions, thus another formula should be used to optimize radio resources in short block-length packet transmission, which is the basic of Ultra-Reliable Low-Latency Communications (URLLCs). The stringent requirement of delay Quality of Service (QoS) for URLLCs requires a link-level channel model rather than a physical level channel model. After finding the basic and accurate formula of the achievable rate of short block-length packet transmission, the RRM optimization problem can be accurately formulated and solved under the new constraints of URLLCs. In this short paper, the current mathematical models, which are used in formulating the effective transmission rate of URLLCs, will be briefly explained. Then, using this rate in RRM for URLLC will be discussed.

Atomic layer deposition (ALD) allows for controlled thin film deposition of a vast variety of materials including exotic ones that can hardly be synthesized by wet chemical methods. The properties of coated supraparticles are defined not only by the nanoparticle material chosen and the nanostructure adjusted during spray‐drying but also by surface functionalities modified by ALD, if ALD is capable of modifying not only the outer surfaces but also surfaces buried inside the porous supraparticle. Simultaneously, surface accessibility in the porous supraparticles must be ensured to make use of all functionalized surfaces. In this work, iron oxide supraparticles are utilized as a model substrate as their magnetic properties enable the use of advanced magnetic characterization methods. Detailed information about the structural evolution upon individual ALD cycles of aluminium oxide, zinc oxide and titanium dioxide are thereby revealed and confirmed by gas sorption analyses. This demonstrates a powerful and versatile approach to freely designing the functionality of future materials by combination of spray‐drying and ALD.

After introducing some general aspects about gender as well as some important properties of the German and Spanish gender systems, this paper compares several formal (morphological and phonological) and semantic rules regarding gender assignment. Despite large structural differences between the languages, the comparison shows that the assignment rules prove to be in a sense cross-lingual, which do not only testify to the assumption but also the validity of an underlying system of rules.

The results of the corpus-driven discourse-linguistic analysis demonstrate in particular metaphors and topoi that can be highlighted as a constitutive part of the discursive construction of a Boca Juniors supporters’ identity and the otherings of River Plate hinchas. Through the use of certain metaphors and determined lexical fields that clearly call for acts of violence, a masculine ethos is discursively constructed among Bocas own followers, which goes far beyond comparable insulting and cheering chants of comparable European football teams.

Schmidt (1987) introduced the term into German to describe bound morphemes that are lexical, but not inflectable. Since the 2000s, an increasing number of publications deal with the phenomenon and the term has begun to enter linguistic reference works as well. In French, the situation is completely different due to the structure of the language (poor in compounds and mostly post-determinative). Although the term and the concept have originall y been coined by the French structuralist André Martinet ([1961] \(^3\)1980 ), the denomination itself is barely present in Romance linguistics. French researchers usually take different approaches to discuss the phenomenon (e.g., neoclassical compounds, constructed lexemes). In Italian, the denominations confisso/ confissazione are first used by De Mauro (1999), who adopts both the term and concept directly from Martinet; moreover, they can be found in some contributions on word formation and lexicology (e.g., Adamo/Della Valle 2008). Nevertheless, the Italian termino-logy remains heterogeneous, with some researchers still using the terms prefissoide/suffissoide coined by Migliorini (1963). As I will show by comparing the languages in question, the terminology and the concept of confixes vary greatly between Romance and Germanic languages.

JF - promptus - Würzburger Beiträge zur Romanistik N2 - In this article dedicated to Jean-Paul Sartre’s first novel La Nausée, we analyze how the idea of conversion to art grows in the imagination of the hero, Antoine Roquentin. Furthermore we show that all the narrative actions in the novel are based on the hero’s communicational interaction with the other characters. This lonely person who complains in his diary about social exclusion, yet he converts to art not through his reflections, but through communica-ting with the other characters. Also, many critical studies on La Nausée have considered jazz music that the hero listens to in a café as the critical moment of his conversion. In our opinion this reflects juste one phase of a connected sequence of events through which the hero passes from a state of relational negativity and existential alienation to a state of openness, achieved again mainly by the virtue of other characters.

Ein spätmoderner Adept Zolas? JF - promptus - Würzburger Beiträge zur Romanistik N2 - French history of literature is undoubtedly characterized by a tradition of social criticism portraying the working class’ misery that can be traced back at least to the 19th century. Among these depictions, Zola’s novels have a prominent position. This is, among other aspects, due to their pretended scientific foundation and their pretentious claims to be scientific studies. The contemporary author Édouard Louis situates himself in this tradition of Zola’s naturalism. This invites us to examine the interrelation between Zola and Louis more closely. Based on the common ground of scientific foundation, scientific ambition and social commitment pursued in their novels, it will be demonstrated that Louis is a late-modern Zola whose milieu and character descriptions follow in detail Zola’s constructions.

However, those conditions seem to possess an aesthetic potential which we seek to analyze in terms of literature. Therefore, we are going to look on three novels from Romance-language areas: Julio Cortázar’s short story La autopista del sur (1966), Carlo Lucarelli’s novel Autosole (1998) and Grégoire Gauchet’s novel Les robinsons de l’autoroute (2018). First, we will analyze the nature of deceleration/congestion by referring to human geographer Tim Cresswell’s concept of friction. Second, we will examine recurring motifs linked to the deceleration/congestion in all novels before taking a closer look at Gauchet’s novel where the friction not only applies to traffic but also to human relationships. The aim is to look at different literary representations of an everyday experience like traffic congestion and to see how literature deals with such an occurrence.

ED - Lazebna, Nataliia ED - Kumar, Dinesh T1 - ESL/EFL in Teaching and Learning Process T2 - Studies in Modern English N2 - Teaching comprises all types of disciplines and teachers need to look outside the confines of English as a Second Language. The acquisition of knowledge comes in a variety of the learners’ educational potential. English as a Second Language in teaching and learning, focuses on active learner’s involvement and reduction of coercion. Indeed, Gibran’s thoughts remain true that “wisdom leads one to discuss his or her potentials. To realize this, teachers in all educational levels have to portray a less dominant classroom role in accord with the importance of classroom interaction in the teaching learning process. N.A. Flaunders retorted that “in the average classroom someone is talking for two-thirds of the time, two-thirds of the task is direct influence.” What does this mean? Students’ participation or interaction in the classroom has a significant content to enhance their linguistic competence and its core basis is how to use the language as the most important factor in the classroom. Comprehending the information caters one to establish a fair and well-balanced condition that teachers are facilitators, and the learners are to stay in the frontline. In today’s classroom setting, the adoption-adaption of teaching strategies focuses on the learners’ ability to have a strong command or fluency of the language. ESL is learned around the globe and the learners’ interests are the primary goals in the teaching and learning pro� cess. Colin Blakemore once said that “True knowledge, as Plato argues, must be within us all, and learning consists of solely of discussing what we already know.” In an ESL classroom, discovery of knowledge is not a new game. Teachers do perform their tasks and the learners serve not as passive listeners but as active recipients in the transformation-sharing of all the five macro skills namely speaking, reading, writing, listening, and viewing. In fact, if commitment, knowledge of subject-matter for independent learning, and management of learning are packaged in one big box, both the teachers and the learners will operate a mutual process of generating a lively culture and quality of educational life. With the aforementioned views I had experienced in teaching ESL, the teacher’s passion for teaching and attitude in dealing with the learners create a strong impact on the learners cognitive, affective, and psychomotor domains.
