TL;DR: The paper presents the architecture and functionality of the principal networking agent?the SECOQC node module, which enables the authentic classical communication required for key distillation, manages the generated key material, determines a communication path between any destinations in the network, and realizes end-to-end secure transport of key material between these destinations.
Abstract: In this paper, we present the quantum key distribution (QKD) network designed and implemented by the European project SEcure COmmunication based on Quantum Cryptography (SECOQC) (2004?2008), unifying the efforts of 41 research and industrial organizations. The paper summarizes the SECOQC approach to QKD networks with a focus on the trusted repeater paradigm. It discusses the architecture and functionality of the SECOQC trusted repeater prototype, which has been put into operation in Vienna in 2008 and publicly demonstrated in the framework of a SECOQC QKD conference held from October 8 to 10, 2008. The demonstration involved one-time pad encrypted telephone communication, a secure (AES encryption protected) video-conference with all deployed nodes and a number of rerouting experiments, highlighting basic mechanisms of the SECOQC network functionality.The paper gives an overview of the eight point-to-point network links in the prototype and their underlying technology: three plug and play systems by id Quantique, a one way weak pulse system from Toshiba Research in the UK, a coherent one-way system by GAP Optique with the participation of id Quantique and the AIT Austrian Institute of Technology (formerly ARC), an entangled photons system by the University of Vienna and the AIT, a continuous-variables system by Centre National de la Recherche Scientifique (CNRS) and THALES Research and Technology with the participation of Universit? Libre de Bruxelles, and a free space link by the Ludwig Maximillians University in Munich connecting two nodes situated in adjacent buildings (line of sight 80?m). The average link length is between 20 and 30?km, the longest link being 83?km.The paper presents the architecture and functionality of the principal networking agent?the SECOQC node module, which enables the authentic classical communication required for key distillation, manages the generated key material, determines a communication path between any destinations in the network, and realizes end-to-end secure transport of key material between these destinations.The paper also illustrates the operation of the network in a number of typical exploitation regimes and gives an initial estimate of the network transmission capacity, defined as the maximum amount of key that can be exchanged, or alternatively the amount of information that can be transmitted with information theoretic security, between two arbitrary nodes.

TL;DR: In this paper, the authors conducted a case study with interviews and document data from four Northern Europe-based forerunner firms with circular economy business models enabled by digital technologies, providing two key contributions to the extant literature.
Abstract: Digital technologies have been increasingly argued to enable circular economy business models. However, the extant research is based on conceptual and review studies, leading to a lack of understanding of how digital technologies enable individual firms in real-life settings to improve their resource flows and value creation and capture and thereby enable business model innovation to emerge. In this study, we conducted a multiple case study with interviews and document data from four Northern Europe-based forerunner firms with circular economy business models enabled by digital technologies, providing two key contributions to the extant literature. First, we generate an empirical evidence -based synthesis of improvements of resource flows and value creation and capture in firms’ businesses across industries, highlighting the critical role of knowledge generation. Second, we develop a model of four key types of business model innovation for circular economy catalyzed by digital technologies, varying on incremental and radical improvement to both the resource flows and value creation and capture, providing theoretical insights to both business model innovation and digital technologies in circular economy. For managers, we suggest suitable digital technologies for the key types, highlighting the importance of radical business model innovation catalyzed by data integration and analysis technologies.

TL;DR: In this article, the authors propose a method for testing one or more OSSs of an ILEC, which includes performing test plans associated with preparation of a test plan for each of the OSS elements.
Abstract: A method for testing one or more OSSs of an ILEC includes performing one or more actions associated with preparation of a test plan for testing one or more elements of the ILEC OSSs, performing one or more actions associated with implementation of a test plan in testing one or more of the ILEC OSS elements, evaluating the performance of the one or more ILEC OSS elements according to the testing, and generating one or more test results according to the evaluation, each test result corresponding to a particular ILEC OSS element tested.

TL;DR: In this paper, metrics-related testing of one or more operational support systems (OSSs) of an incumbent provider for compliance with a regulatory scheme, the method performed by an independent testing entity attempting to emulate a competitive provider that would access the OSSs in attempting to compete with the incumbent provider in an open competitive market.
Abstract: Methods are provided for metrics-related testing of one or more operational support systems (OSSs) of an incumbent provider for compliance with a regulatory scheme, the method performed by an independent testing entity attempting to emulate a competitive provider that would access the OSSs in attempting to compete with the incumbent provider in an open competitive market. Each method includes an active testing phase in which one or more OSSs are tested. Performance of the incumbent provider during active testing is evaluated according to predetermined evaluation criteria. Test results are generated according to the evaluation and a final report is issued. The final report includes the test results and provides a sufficient basis for a regulatory entity administering the regulatory scheme to determine compliance of the incumbent provider with the regulatory scheme.

TL;DR: This paper reviews 175 scholarly empirical publications on mobile Internet usage intensity levels and potential determinants of respective usage behavior at the individual subscriber level and concludes that mono-method work which measures both explanatory factors and MI usage in one questionnaire was prone to overestimate relationships between independent study variables and self-reports of MI usage.
