AbstractThe Technical Division “Engineering and Operation of automated plants” of the VDI-/VDE-GMA (German Association of Measurement and Automation) elaborates new approaches for an efficient engineering and operation of equipment and automated plants. Within this Division, technical committee 6.12 “Integrated engineering of automated systems” has analyzed and refined the concept of an integrated plant model over all phases of a plant’s life, since this has the potential to generate high synergy potentials by means of model reuse and early integration. Previous work of the technical committee 6.12 has addressed the changes in the value network from a business perspective. The present contribution describes how an integrated plant model should be built, maintained and used. The approach is explained in a generic way from a usage view, by the description of the system under consideration, the acting technical stakeholders and the activities that can, or must, be carried out. The approach is then elucidated by means of an example.

With an increasing employment of technology the medical quality of treatment may rise. But, at the same time, the complexity of the medical equipment rises as well. This leads to an increase of the required interactions between user and technology. Therefore, a higher work loading for the medical and nursing personal is consequential. New requirements to the safety and the quality of use of medical devices and systems result from the increasing employment of technology. For the acquisition of devices users and operators need to pay attention to the possible sources of error in handling and use as well as to the possibility to decrease operating and process costs by foresighted purchase decisions. The German Association of Biomedical Engineering (DGBMT) considered the ergonomics of medical products as an important topic and established the Technical Committee of Ergonomics in Medical Engineering. The members of this technical committee compiled a paper describing the most important issues and intentions being partly presented in the following.

The aim of the scientific work is to assess the level of information security of the automated enterprise systems using modelling based on the concept of digital twins of production. The article is devoted to solving the problem of constructing a model that is a digital twin of the enterprise automated systems. Within the framework of a systematic approach, solving this problem implies modelling environmental conditions, software and hardware reliability, as well as the human factor. The novelty of the work is the proposed creative concept of using the digital twin technology for a detailed assessment of the information security level of the automated systems. The study findings are the recommendations for assessing the level of information security using a digital twin.

AbstractSince 2016, a new version of the VDI (German Association of Engineers) Guideline 2206 has been developed by the Technical Committee VDI GMA 4.10 “Interdisciplinary Product Creation”. This article presents the revision results of the VDI Guideline 2206:2004 “Design methodology for mechatronic systems”. The core content of the guideline is an updated and enhanced V-Model for Mechatronic and Cyber-Physical Systems. The inherent concern logic of the V-Model represents the logical sequence of tasks. Its key advantage lies in staying independent from the chosen form of project organization. This way, the V-Model can be applied in classically managed projects as well as in agile projects. In addition, the article describes how the revision was performed and which potentials were tapped. Based on the identified potentials, the new V-Model is derived, explained and illustrated. New contents such as the introduction of checkpoints and the integration of requirements engineering are explained in detail. Furthermore, the pursued scientific procedure and the results of the International Validation Workshop with 25 experts from science and industry are proposed.

Abstract International Organization for Standardization (ISO) Technical Committee (TC) 209’s first meeting was held in November 1993.The focus was on cleanrooms and controlled environments and the activities within cleanrooms. The TC has moved in recent years to generic operations documents such as a systematic approach for procuring disposables and particle deposition rate monitoring to improve the quality of products manufactured in a cleanroom. ISO stresses development of standards with requirements to support sustainability. A recently published standard on energy management in a cleanroom supports that need. ISO has a range of publication formats with different rigor in balloting to reduce document development being considered by the TC. ISO/TC 209 begins its third decade taking a more integrated approach to standardization with the goal of responding to the needs of industry.

Democratisation is a topic that is increasingly finding its way into the economic debate and is also becoming more and more of a trend within companies. The debates reveal various advantages and disadvantages of democratising companies. Within the various models of democratisation of companies, however, there seems to be a lack of coherent integration of the theoretical integration of this into the broad corporate structures – at least within business perspective. These often refer to orthodox theoretical foundations of hierarchical structures and corporate orientations, which in principle oppose and partly run counter to various forms of democratisation. In the present contribution, minimal conditions are to be worked out on the basis of democracy as cooperation and applied to the most elementary corporate structures. In such a coherent orientation and embedding, it can be shown that disadvantages of democratisation in the corporate context can be reduced and innovation and thus competitiveness can be promoted in a multidimensional way.

It is currently well established that, for an Al-Ag alloy quenched from the α phase and aged within the metastable solvus, the aging sequence is: supersaturated α → GP zones → γ’ → γ (Ag2Al). While GP zones and plate-shaped γ’ are metastable phases, continuously distributed in the matrix, formation of the equilibrium phase γ takes place at grain boundaries by discontinuous precipitation (DP). The crystal structure of both γ’ and γ is hep with the following orientation relationship with respect to the fee α matrix: {0001}γ′,γ // {111}α, <1120>γ′,γ, // <110>α.The mechanisms and kinetics of continuous matrix precipitation (CMP) in dilute Al-Ag alloys have been studied in considerable detail. The quantitative description of DP kinetics, however, has received less attention. The present contribution reports the microstructural evolution resulting from aging an Al-Ag alloy with Ag content higher than those previously reported in the literature, focusing the observations of γ' plate-shaped metastable precipitates.

Students with persistent reading difficulties are often especially challenged by multisyllabic words; they tend to have neither a systematic approach for reading these words nor the confidence to persevere (Archer, Gleason, & Vachon, 2003; Carlisle & Katz, 2006; Moats, 1998). This challenge is magnified by the fact that the vast majority of English words are multisyllabic and constitute an increasingly large proportion of the words in elementary school texts beginning as early as grade 3 (Hiebert, Martin, & Menon, 2005; Kerns et al., 2016). Multisyllabic words are more difficult to read simply because they are long, posing challenges for working memory capacity. In addition, syllable boundaries, word stress, vowel pronunciation ambiguities, less predictable grapheme-phoneme correspondences, and morphological complexity all contribute to long words' difficulty. Research suggests that explicit instruction in both syllabification and morphological knowledge improve poor readers' multisyllabic word reading accuracy; several examples of instructional programs involving one or both of these elements are provided.
