Industry 4.0

Во всем мире традиционная обрабатывающая промышленность находится в процессе цифрового преобразования, которое вызвано стремительно растущими технологиями (например, роботы, автономные беспилотные летательные аппараты, 3D- печать). Компании и их производственные процессы должны подстроиться под эти быстрые изменения, если они не хотят отстать от развития их индустрии. Around the world, traditional manufacturing industry is in the throes of a digital transformation that is accelerated by exponentially growing technologies (e.g. intelligent robots, autonomous drones, sensors, 3D printing). Companies and their industrial processes need to adapt to this rapid change if they are not to be left behind by developments in their sector and by their competitors

Mobility in a Globalised World 2012

The term mobility has different meanings in the following science disciplines. In economics, mobility is the ability of an individual or a group to improve their economic status in relation to income and wealth within their lifetime or between generations. In information systems and computer science, mobility is used for the concept of mobile computing, in which a computer is transported by a person during normal use. By designing logistics networks, logistics creates the infrastructure for the mobility of people and goods. Electric mobility is one of today’s solutions from an engineering perspective to the problem of reducing the need for energy resources and environmental impact. Finally, for urban planning, mobility is the crunch question as to how to optimise the different needs for mobility and how to link different transportation systems. In this publication we have collected the ideas of practitioners, researchers, and government officials about the different modes of mobility in a globalised world, focusing on both domestic and international issues

Helium-Diffusion in Nickel bei hohen Temperaturen

Helium has been implanted at certain temperatures between 800 and 1250 °C into single and polycrystalline Ni-samples with implantation depths between 15 and 90 $\mu$m. Simultaneously the helium reemission from the sample is measured by a massspectrometer. It has been shown that the time dependence of the observed reemission rate is governed by volume diffusion of the helium. Measuring this time dependence as a function of temperature the helium diffusion constant has been determined to D$_{He}$ = 10$^ {-2.2\pm0.3}$ . e^ {0.81\pm0.04 eV/k \cdotT} cm$^{2}$/sec The He-diffusion is interpreted as a interstitial diffusion hindered by thermal vacancies. Within this model the measured activation energy can be identified with the difference of the energy for dissoziation of a helium atom from its substitutional lattice site[...

Report on an informal meeting on hydrogen transport and solubility in carbon materials

On the occasion of the 8th international conference onplasma surface interaction in Jülich an informal meeting washeld in Aachen, the 5 of May. The aim of this meeting was todiscuss the present knowledge on transport and solubility ofhydrogen in carbon and to recommend future work necessary inthis field. This report summarises the main topics discussedin this meeting.On the basis of two excellent invited talks by W. Möller[l] and R. Causey (2] the discussion was concentrated on thehydrogen behaviour in the saturated surface layer (or a-C:H films) and in the unmodified carbon material.In the saturated layer the hydrogen behaviour has beendiscussed according to the following scenario:- implantation- thermalisation- trapping- ion induced and thermal detrapping- internal recombination to molecules- subsequent migration and release of the molecules
