A practical development of engineering simulation-assisted educational AR environments

Engineering simulations have opened several gates for today’s chemical engineers. They are powerful tools to provide technical content as physics-based numerical solvers. Augmented reality (AR) and virtual reality (VR), on the other hand, are already underway to digitize environments in many fields. The combination of AR/VR environments and simulations in engineering education has been attracting widespread interest. Literature has demonstrated a massive amount of digital educational environments in several contexts as being complementary to conventional educational methods. Nevertheless, hosting technical content produced by engineering simulations with educational AR/VR is still challenging and requires expertise from multiple disciplines throughout the technical development. Present work provides a facile and agile methodology for low-cost hardware but content-wise rich AR software development. Inspired by the Covid-19 pandemic, a case study is developed to teach chemical-engineering concepts using a liquid-soap synthesis process. Accordingly, we assess and conclude the digital development process to guide inexperienced developers for the digitalization of teaching content. The present contribution serves as an example of the power of integrating AR/VR with traditional engineering simulations for educational purposes. The digital tool developed in this work is shared in the online version.     

“These devices have not been made for older people's needs” – Older adults' perceptions of digital technologies in Finland and Ireland

This article examines how older adults use and perceive digital technologies in Finland and Ireland. These two countries are at different stages regarding two important global trends – demographic ageing and digitalization. Finland, being the fastest ageing society in Europe, is also one of the leaders in implementing digital technologies in social and health care services. In contrast, Ireland is a demographically younger and less digitalized society. Drawing on focus group discussions on the usage of digital technologies, conducted with older adults in both countries, we analyse how digital technologies are adopted and viewed by older generations. The analyses showed that older adults associate digitalization with both advantages and drawbacks. To encapsulate these two contrasting aspects, we developed the term Janus-faced conceptions of technology. This concept encapsulates how the successful adoption of digital technology facilitates everyday activities whereas the inability to utilise technologies results in feelings of alienation and being out-of-touch. The digital divide was found to occur not only between generations but also between different socioeconomic groups of older adults.

汽车数字供应链SaaS化新管理模式探究与实践

随着现代技术的发展,汽车产业孕育着新一轮升级。目前,汽车企业间的竞争逐步加大,已经逐步转化为供应链的竞争。而传统供应链生产管理仍然面临着市场高质量、高交期的巨大挑战,无法满足汽车企业对其生产效率的需求。因此,新的汽车供应链管理模式应运而生。研究了汽车数字供应链软件即服务(SaaS)化新管理模式,并基于SaaS平台实现探索供应链数字化管理的新生态模式。以某汽车公司为例,进行供应链SaaS生态平台实践研究,以数字化制造重塑供应链流程,解决供应链企业间数据协同,实现汽车全产业链互联互通、结构性降本增效,打造高效协作、互利共赢的新型行业生态模式。采用SaaS平台实现供应链生产管理后,其供应链管理数字化延伸,生产线开动率提升了1%,协同效率大幅提升。     

Systematically mapping innovations in electricity using startups: A comprehensive database analysis

Technology innovation is recognized as one of the main enablers of sustainable development and the transition towards a low-carbon future. Anticipating innovation trajectories could help decision-makers develop new capabilities to take advantage of incremental and disruptive innovations. This paper maps the current innovation that is taking place in the electricity sector using a bottom-up approach by analyzing the value proposition pursued by startups worldwide.We compiled a database of 320 startups whose focus is the electricity sector. We classified these startups according to their business propositions in the context of megatrends disrupting the electricity sector. From analyzing this dataset, we find the following. Photovoltaic generation (PV) is the primary technology for decarbonization. Innovation within PV focuses on developing more resistant materials, panels that are easier to install, or maintain. These innovations do not need an updated regulatory-market structure of the industry to be deployed. Digitalization is the key disruptive/breakthrough innovation. It has the potential to reshape businesses and the regulatory-market structure. Storage technologies can be very disruptive for the power sector, but the innovation we observe in storage technology is incremental. This includes batteries that last longer, that charge in shorter periods of time, or that use other less expensive raw materials, or more energy density –more kilowatt-hours per kilogram.
