Development of Mobile Machining Cell

This report covers some initial aspects of development of the mobile InnoMill machining cell. The new machining paradigm where the machine is mounted on the workpiece is compared to the old paradigm where the workpiece is mounted inside the machine, and differences are discussed. Parametric studies of the workpiece case study of the InnoMill project, the Vestas V112-3.0MW wind turbine hub, are performed to supply insight regarding load capacity etc. for the machine designers. The hub finite element model is validated using experimental results from Operational Modal Analysis performed on the hub. Furthermore, the InnoMill concept is described, and work regarding the 6 degree of freedom parallel kinematic manipulator which is present in the concept is performed. A numerical procedure accounting for base deflections due to static loading is proposed and implemented. Additionally, a six degree of freedom spring-mass model vibrational response is compared to vibrational response obtained from experiments on the 6 degree of freedom parallel kinematic manipulator at Aarhus University. The model, which is based on assumptions commonly found in literature, is rejected. Finally, an outlook for the remaining part of the PhD project is presented

The fourth volume of the International Journal of Homiletics opens with an article from South Africa presenting first results of an empirical research on preaching in times of the pandemic. Marileen Steyn, Cas Wepener and Hennie Pieterse, all three from Stellenbosch University, conducted a grounded theory exploration on Preaching During the COVID-19 Pandemic in South Africa analyzing 24 sermons preached on March 22 and March 29 2020- during the time of the South African lockdown. They convincingly show that in an experience of ‘distance’ (to God and the others) sermons primarily try to present a God who is ‘near.’ The authors explore the ‘hinges’ preachers use to help people on the threshold between near and far. They also point to the role liturgy plays together with the words of the sermon and suggest Holy Saturday/Silent Saturday as a metaphor for the homiletical endeavor of preaching in times of crisis. The article is presented in our volume in an English and an Afrikaans version

Welcome to the Supplementum issue of the International Journal of Homiletics. The articles in this volume are edited, peer-reviewed versions of keynote lectures and papers1 presented at the Societas Homiletica Conference on August 3rd – 8th 2018, at The Divinity School of Duke University, North Carolina, USA. The theme of the conference was “Fearing God in a Fear-Filled World? Homiletical Explorations” – a topic that resonated with homileticians from all over the world and engendered rich reflections and discussions during the conference. In what follows are four keynote lectures, a keynote response and six papers discussing the theme of fear from theological perspectives of South Africa, Brazil, Australia, Germany, the Netherlands, Sweden, and the United States

2020 – this year will surely be remembered as the year of the Covid19-pandemic. Writing these lines in August 2020, there are around 20 million people infected (numbers increasing continuously) – and the whole population of the world affected by the virus. 750.000 people died in the first months of the pandemic. And all over the world poverty increases, and the most vulnerable are most affected by the crisis. Are there any ‘answers’ sermons can give? Or is this a time for silently listening with the congregations to the word of God? What is the role of preaching in the pandemic – knowing that we will never simply return to the situation ‘before’ the pandemic, but that our way of living, and also our way of preaching and celebrating worship will change
