TL;DR: The effect of the lubrication on the mechanical behavior of magnetorheological elastomers (MREs) in compression mode is experimentally studied in this paper , where isotropic and anisotropic MREs with iron particle volume concentrations of 10, 20, 30 and 40% were tested under different strain amplitudes, prestrain and magnetic fields for a frequency range up to 300 Hz, with and without lubrication.

TL;DR: In this article , a set of guidelines on the use of the torsion pendulum for the viscoelastic characterisation of carbon black reinforced rubber is presented, including the set up selection, the post processing steps and the final evaluation of the method using temperature sweep results at small strains.

TL;DR: In this paper , the authors highlight the experiences from ten years of implementing sustainable development in all educational programs at a technical university and conclude that the evolution of a web of interconnected people, key academics, activities, norms and tools has contributed to an increased participation.
Abstract: ABSTRACT This work spotlights the experiences from ten years of implementing sustainable development in all educational programs at a technical university. With a focus on the critical issue of involving more academics in the work, experiences are shared through an ethnographic account including focus group interviews. ‘Sustainable development’ has been perceived as both superficial and overwhelming; unclear yet somehow predetermined; it has been perceived to demand non-existent space in the curriculum; and it has challenged the academics regardless of the subjects’ relatedness to sustainability. It is concluded that the evolution of a web of interconnected people, key academics, activities, norms and tools has contributed to an increased participation. The work for authenticity, reliability and feasibility, along with institution-wide and long-term academic development tools is presented.

TL;DR: In this paper , a flywheel mounted centrifugal pendulum absorber (CPVA) is designed to completely suppress the low frequency shuffle-mode resonance of a heavy-duty truck powertrain by exploiting the eigenfrequency veering property of the CPVA.
