AbstractIn this chapter, we posit that academics need to reduce their flying in line with the ‘Carbon Law’ if we are to attain the agreed-upon targets of the Paris agreement. This entails reducing emissions in general as well as reducing emissions from flying by at least 50 per cent every decade from 2020 and on. We present data from KTH Royal Institute of Technology regarding our flying and use two specific departments as examples. We unpack this data, using material visualisations (i.e. post-it notes and poker chips) to raise questions that are not immediately apparent when looking at top-down statistics about flying. Our material visualisations instead present data about flying patterns and habits in a format that viscerally displays the differences (‘inequalities’) that exist between and within departments. Such visualisations emphasise that reducing the frequency and the length of air trips will inevitably lead to discussions and negotiations about who gets to fly (or not), as well as discussions about exactly what constitutes ‘unnecessary’ flights. The chapter ends with a reflection about the limitations of our language and how the task of reducing carbon emission from flying necessitates a reinvention of how we think and talk about flying.

This paper describes the experimental setup, instrumentation and procedures which have been developed in the thermal-hydraulic laboratory at the Royal Institute of Technology (KTH), Stockholm, Sweden, to perform new post-dryout heat transfer investigations in an annulus with flow obstacles. Previous investigations performed in the same laboratory indicated that flow obstacles had a considerable influence on the post-CHF heat transfer. The measured heat transfer enhancement was significantly under-predicted by existing models. However, the net effect of obstacles could not be deduced from the measurements, since reference - obstacle-free measurements - had not been performed. In addition, the number of thermocouples that could be installed inside the heated rod was limited to 8. These deficiencies have been removed in the current approach. Firstly, the present design of the test section allows for measurements both with and without flow obstacles. In this way the net effect of the obstacles will be captured. Secondly, a newly developed technique allowed the installation of 40 thermocouples inside of the heated rod. An additional 40 thermocouples have been installed on the external wall of the heated tube. Therefore, a significant improvement of the accuracy of measurements can be expected. The present arrangement of instrumentation is suitable to perform measurements of heat transfer under both steady-state and transient conditions.

This article offers an overview of the two key outcomes of the 2015 Paris climate negotiations, the Paris cop decision, and the Paris Agreement. Collectively, they chart a new course for the un climate regime that started in earnest in Copenhagen in 2009. The Paris Agreement represents a path away from the top-down approach and rigid differentiation among parties reflected in the Kyoto Protocol, toward a bottom-up and flexible approach focused on collective long-term goals and principles. It represents an approach to reaching these long-term goals that is focused on self-differentiation, support, transparency, and review. The article highlights the key elements of the agreement reached in Paris, including its approach to mitigation, adaptation, loss and damage, finance, transparency, and compliance.

The urgent need for actions in the light of the global challenges motivates international policy to define roadmaps for education on all levels to step forward and contribute with new knowledge and competencies. Challenge-Driven Education (CDE) is described as an education for Sustainable Development (ESD) approach, which aims to prepare students to work with global challenges and to bring value to society by direct impact. This paper describes, evaluates and discusses a three-year participatory implementation project of Challenge-driven education (CDE) within the engineering education at the University of Dar es Salam, UDSM, which has been carried out in collaboration with the Royal Institute of Technology, KTH in Stockholm. Conclusions are drawn on crucial aspects for engineering education change through the lens of Activity Theory (AT), where CDE is brought forward as a motivating ESD initiative for engineering faculty and students. Furthermore participatory co-creation is notably useful as it aims to embrace social values among the participants. Also, traditional organizational structures will need to be continuously negotiated in the light of the integration of more open-ended approaches in education.

Speech Information

Tests of tactual speech perception were conducted using a special frequency-analyzing vocoder. The vocoder presented a running frequency analysis of speech mapped into a spatial array of tactual vibrations which were applied to the fingers of the receiving subject. Ten vibrators were used, one for each finger. The position of a vibrator represented a given frequency region of speech energy; the total range covered was 210 to 7 700 cps; all the vibrations had a frequency of 300 cps; the vibration amplitudes represented the energy distribution over the various frequencies. Discrimination and identification tests were performed with various sets of test vowels; consonant discrimination tests were performed with certain consonants including those that might be difficult to lipread. Performance with vowels appeared to be related to formant structure and duration as measured on the test vowels, and to tactual masking effects. Consonant discrimination was good between stops and continuants; consonant features of nasality, voicing, and affrication were also discriminated to some extent. It is concluded that the skin offers certain capacities for transmitting speech information which may be used to complement speech communication where only an impoverished speech signal is normally received. This research was conducted at the Speech Transmission Laboratory, Royal Institute of Technology, Stockholm, Sweden.

The Swedish multiinstitutional research program MultiG spawned a number of research projects concerned with telecommunication, telecollaboration, and telepresence. One of these projects is DIVE (Distributed Interactive Virtual Environments), a multiuser virtual reality system developed jointly by the Swedish Institute of Computer Science and the Royal Institute of Technology in Stockholm, Sweden. DIVE is used as the platform for research in collaborative work in virtual spaces. In cooperation with the universities of Lancaster, Manchester, and Nottingham, the DIVE group has developed a spatial model for interaction. In this model each participant defines subspaces for their presence and attention. The intersection of those subspaces provides for varying degrees of mutual awareness, which is presumed to support more natural human-human interaction in virtual environments.
