Multiple Product

The concept of product view and the corresponding required models is a basic constituent of a product development process. Integration across product views is addressed through an analysis of the key characteristics of current geometric modellers. Here, topological and geometric issues are identified and major shape modelling principles are studied. As a result, the core concepts of a framework for product view integration are proposed and justified. The notions of mixed shape representation and layered topological representation are briefly outlined as part of the proposed framework. Categories of operators enabling the required shape transformations are also shortly introduced as element of the proposed framework.

This paper focuses on the study of IoT network deployments, in both unlicensed and licensed bands, considering LoRaWAN and NB-IoT standards, respectively. The objective is to develop a comprehensive and detailed network planning and coverage dimensioning methodology for assessing key metrics related to the achieved throughput and capacity for specific requirements in order to identify tradeoffs and key issues that are related to the applicability of IoT access technologies for representative use case types. This paper will provide a concise overview of key characteristics of IoT representative IoT access network standards that are considered for being deployed in unlicensed and licensed bands and will present a methodology for modeling the characteristics of both access network technologies in order to assess their coverage and capacity considering different parameters.

Purpose – The purpose of this article is to provide an overview of key issues and concepts related to discussions of the internet, its governance, and its multi-stakeholder model. Design/methodology/approach – The method adopted is to discuss definitions of internet, to identify the key characteristics of internet, to define the multi-stakeholder approach, and to discuss the results it has achieved. Findings – The article finds that the internet is different from other networks, albeit not exactly in the ways that are commonly mentioned, and it finds that the internet's current governance mechanisms can be improved, in particular by increasing the role of more traditional governance mechanisms such as intergovernmental organizations. Originality/value – The analysis and conclusions are not found in previous literature, and they are meant to provoke further research and discussion.

The growth and convergence of wireless telecommunications and ubiquitous networks has created a tremendous potential platform for providing business services. In consumer markets, mobile marketing is likely to be a key growth area. The immediacy, interactivity, and mobility of wireless devices provide a novel platform for marketing. The personal and ubiquitous nature of devices means that interactivity can, ideally, be provided anytime and anywhere. However, as experience has shown, it is important to keep the consumer in mind. Mobile marketing permission and acceptance are core issues that marketers have yet to fully explain or resolve. This chapter provides direction in this area. After briefly discussing some background on mobile marketing, the chapter conceptualises key characteristics for mobile marketing permission and acceptance. The chapter concludes with predictions on the future of mobile marketing and some core areas of further research.

Reliability And Robustness

The importance of design robustness and reliability is a well-established notion and practice in today’s industry. Manufacturing companies strive to achieve Six-Sigma quality measures. While Virtual Prototyping is a key-factor in accelerating the product development process while reducing development costs, it has not contributed in the quest for improved product reliability and robustness performance since it is based on deterministic approaches. This paper provides a systematic approach to design for six-sigma simultaneously addressing variability and uncertainty present in real life on most design parameters. An example from the automotive industry illustrates the methodologies.

Shape Processing

Proximal mirroring of distal similarities is, at present, the only solution to the problem of representation that is both theoretically sound (for reasons discussed in the target article) and practically feasible (as attested by the performance of the Chorus model). Augmenting the latter by a capability to refer selectively to retinotopically defined object fragments should lead to a comprehensive theory of shape processing.

This article is part of the special cluster titled Conceptualizations of the Holocaust in Germany, Lithuania, Poland, and Ukraine since the 1990s, guest edited by Grzegorz Rossoliński-Liebe. The Holocaust is the darkest page of Lithuanian history: Nearly the whole Jewish community in Lithuania was destroyed, while a part of ethnic Lithuanians participated in this destruction. This article discusses three layers and periods of the Holocaust in Lithuania that have made a considerable impact on the perception of this traumatic period in Lithuanian society. The first period deals with the Lithuanian–Jewish relations during the German occupation in Lithuania (1941–1944). The second one is related to the Soviet reoccupation of Lithuania and discussions among Lithuanian émigrés in the West (1944–1990), which shaped the history of the Holocaust in Lithuania from the ideological (Soviet) and defensive (Lithuanian émigré) perspectives. The final part of this article discusses the historiography and Holocaust memory in independent Lithuania after the 1990s. Almost thirty years of independence mark not only the re-creation of some old myths and stereotypes in Lithuania, but also new groundbreaking and open discussions in society, concerning the perception of this dark page of Lithuanian history.
