RFID-based Business Models

During the implementation, upgrade and disposal of RFID-applications different tasks have to be performed. Since most companies outsource a great share of these activities, there is profit potential for service providers. The article introduces a typology for RFID-enabled and -supported services as well as support services. Potentially all sub processes can be outsourced to service providers. The RFID-process landscape presented in this article can help the users to identify processes for outsourcing. The case study within the article described the organization of a tag cycle for reusable RFID-tags as potential service offering

Cost-Benefit Sharing in Cross-Company RFID Applications: A Case Study Approach

Although the highest potential for RFID in logistics is expected to be realized in cross-company applications, the status quo in the RFID project landscape is dominated by isolated solutions in specific fields. Reasons for this phenomenon are the high investment costs and the difficulty in assessing the benefits during the run-up phase. In network technologies such as RFID, the benefits depend on the spread of the technology in the network. A high discrepancy may result between the occurring costs and the resulting benefits for each of the network partners. This unequal distribution puts the success of the application at risk. To counter this trend, a balancing of costs and benefits should be considered. The research question of this paper is how these costs and benefits should be distributed among which participants. To develop a practical, relevant solution, we use an empirical research method based on an exploratory case study

RFID in der Logistik : Empfehlungen für eine erfolgreiche Einführung

Gefördert vom BMWi unter Förderkennzeichen 01MG515Die RFID-Technologie zählt seit einigen Jahren zu den meistdiskutierten Innovationen in der Logistik. Aufgrund der zahlreichen Einsatzmöglichkeiten in nahezu allen Branchen und den nicht zu bestreitenden Vorteilen gegenüber anderen Identifikationstechnologien nimmt die Verbreitung von RFID stetig zu. Im Einzelfall ergibt sich jedoch ein sehr differenziertes Bild. So weiten zahlreiche Unternehmen ihre RFID-Aktivitäten weiter aus und leisten mit dem Einsatz der Technologie einen wertvollen Beitrag zur Effizienzsteigerung ihrer Logistik. Andererseits kommt eine Vielzahl von Projekten kaum über die Konzeptphase hinaus oder wird nach einem kurzen Pilotbetrieb eingestellt. Was also macht eine erfolgreiche RFID-Implementierung aus? Warum sind einige Unternehmen erfolgreich, wo andere scheitern? Welche Strategien eignen sich für die Einführung der Technologie? Welche Tätigkeiten sind entscheidend für einen Implementierungserfolg? Wie können die richtigen Lösungspartner gewählt werden? Um Antworten auf diese Fragen zu finden, wurde eine Befragung durchgeführt, an der sich mehr als 150 Anwender und Systemanbieter beteiligt haben. Bei der Auswertung werden die Sichtweisen der Anwender und der Systemanbieter gegenübergestellt, branchenbezogene Analysen durchgeführt sowie Strategien der erfolgreichsten Anwender herausgearbeitet und in Handlungsempfehlungen übersetzt.

Yield Progress in Forage Maize in NW Europe—Breeding Progress or Climate Change Effects?

Yield increases in forage maize (Zea mays L.) in NW Europe over time are well documented. The driving causes for these, however, remain unclear as there is little information available regarding the role of plant traits triggering this yield progress. Ten different hybrids from the same maturity group, which have typically been cultivated in Northwest Germany from 1970 to recent and are thus representing breeding progress over four decades, were selected for a 2-year field study in northern Germany. Traits that were investigated included leaf area index, leaf architecture, photosynthesis, radiation use efficiency, root mass, root length density, and turnover. Based on a mixed model analysis with these traits as co-variates, parameters related to leaf characteristics, in particular the number and length of leaves, the radiation use efficiency, and the leaf orientation, were identified as most influential on the yield progress (0.13 tons ha-1 year-1). In contrast to our hypothesis, root biomass only increased negligibly in newer hybrids compared to older ones, confirming the ‘functional equilibrium’ theory for high input production systems. Due to an abundance of nutrients and water in such high input systems, there is no incentive for breeders to select for carbon partitioning toward the rooting system. Breeding evidence to increase forage quality were also negligible, with no change in cob starch concentration, forage digestibility, nor NDF content and NDF digestibility. The observed increase in yield over the last four decades is due to a combination of increased temperature sums (~240 GDD within 40 years), and a higher radiation interception and radiation use efficiency. This higher radiation interception was driven by an increased leaf area index, with a higher number of leaves (16 instead of 14 leaves within 40 years) and longer leaves of newer compared to older hybrids. Future selection and adaptation of maize hybrids to changing environmental conditions are likely to be the key for high productivity and quality and for the economic viability of maize growing and expansion in Northern Europe

Graph Data-Models and Semantic Web Technologies in Scholarly Digital Editing

This volume is based on the selected papers presented at the Workshop on Scholarly Digital Editions, Graph Data-Models and Semantic Web Technologies, held at the Uni- versity of Lausanne in June 2019. The Workshop was organized by Elena Spadini (University of Lausanne) and Francesca Tomasi (University of Bologna), and spon- sored by the Swiss National Science Foundation through a Scientific Exchange grant, and by the Centre de recherche sur les lettres romandes of the University of Lausanne. The Workshop comprised two full days of vibrant discussions among the invited speakers, the authors of the selected papers, and other participants.1 The acceptance rate following the open call for papers was around 60%. All authors – both selected and invited speakers – were asked to provide a short paper two months before the Workshop. The authors were then paired up, and each pair exchanged papers. Paired authors prepared questions for one another, which were to be addressed during the talks at the Workshop; in this way, conversations started well before the Workshop itself. After the Workshop, the papers underwent a second round of peer-review before inclusion in this volume. This time, the relevance of the papers was not under discus- sion, but reviewers were asked to appraise specific aspects of each contribution, such as its originality or level of innovation, its methodological accuracy and knowledge of the literature, as well as more formal parameters such as completeness, clarity, and coherence. The bibliography of all of the papers is collected in the public Zotero group library GraphSDE20192, which has been used to generate the reference list for each contribution in this volume. The invited speakers came from a wide range of backgrounds (academic, commer- cial, and research institutions) and represented the different actors involved in the remediation of our cultural heritage in the form of graphs and/or in a semantic web en- vironment. Georg Vogeler (University of Graz) and Ronald Haentjens Dekker (Royal Dutch Academy of Sciences, Humanities Cluster) brought the Digital Humanities research perspective; the work of Hans Cools and Roberta Laura Padlina (University of Basel, National Infrastructure for Editions), as well as of Tobias Schweizer and Sepi- deh Alassi (University of Basel, Digital Humanities Lab), focused on infrastructural challenges and the development of conceptual and software frameworks to support re- searchers’ needs; Michele Pasin’s contribution (Digital Science, Springer Nature) was informed by his experiences in both academic research, and in commercial technology companies that provide services for the scientific community. The Workshop featured not only the papers of the selected authors and of the invited speakers, but also moments of discussion between interested participants. In addition to the common Q&A time, during the second day one entire session was allocated to working groups delving into topics that had emerged during the Workshop. Four working groups were created, with four to seven participants each, and each group presented a short report at the end of the session. Four themes were discussed: enhancing TEI from documents to data; ontologies for the Humanities; tools and infrastructures; and textual criticism. All of these themes are represented in this volume. The Workshop would not have been of such high quality without the support of the members of its scientific committee: Gioele Barabucci, Fabio Ciotti, Claire Clivaz, Marion Rivoal, Greta Franzini, Simon Gabay, Daniel Maggetti, Frederike Neuber, Elena Pierazzo, Davide Picca, Michael Piotrowski, Matteo Romanello, Maïeul Rouquette, Elena Spadini, Francesca Tomasi, Aris Xanthos – and, of course, the support of all the colleagues and administrative staff in Lausanne, who helped the Workshop to become a reality. The final versions of these papers underwent a single-blind peer review process. We want to thank the reviewers: Helena Bermudez Sabel, Arianna Ciula, Marilena Daquino, Richard Hadden, Daniel Jeller, Tiziana Mancinelli, Davide Picca, Michael Piotrowski, Patrick Sahle, Raffaele Viglianti, Joris van Zundert, and others who preferred not to be named personally. Your input enhanced the quality of the volume significantly! It is sad news that Hans Cools passed away during the production of the volume. We are proud to document a recent state of his work and will miss him and his ability to implement the vision of a digital scholarly edition based on graph data-models and semantic web technologies. The production of the volume would not have been possible without the thorough copy-editing and proof reading by Lucy Emmerson and the support of the IDE team, in particular Bernhard Assmann, the TeX-master himself. This volume is sponsored by the University of Bologna and by the University of Lausanne. Bologna, Lausanne, Graz, July 2021 Francesca Tomasi, Elena Spadini, Georg Vogele

RFID: Grundlagen und Potenziale

Die Radio Frequenz Identifikation (RFID) erlaubt es, Objekte mit Transpondern zu versehen und sie dadurch eindeutig zu identifizieren sowie drahtlos Daten auszutauschen. Das Potenzial der RFID erstreckt sich dabei weit über die einfache Identifikation von Objekten und bietet die Möglichkeit, Daten lokal zu speichern, sensorisch zu erfassen und am Objekt zu verarbeiten bzw. Steuerungs-entscheidungen zu treffen. Für die volle Ausschöpfung dieses Potenzials sind technologische Fragestellungen der Integration der RFID in technische Systeme zu erforschen, Standardisierungsvorhaben mit dem Ziel einer global einsetzbaren Technik voranzutreiben und Anwendungen zu forcieren, in denen Transponder über die Grenzen geschlossener Kreise eingesetzt werden. Vision ist ein universell einsetzbares, kostengünstiges Processing Label (PL), das die Funktionalitäten der Datenspeicherung, Sensordatenerfassung und Datenverarbeitung vereint

Informatics for historians : tools for medieval document XML Markup, and their impact on the History-Sciences

This article is a revised and extended version of [VBG, 07]. We conjecture that the digitalization of historical text documents as a basis of data mining and information retrieval for the purpose of progress in the history sciences is urgently needed. We present a novel, specialist XML tool-suite supporting the working historian in the transcription of original medieval charters into a machine-readable form, and we also address some latest developments which can be found in the field since the publication of [VBG, 07]
