Konferensbidrag (refereegranskat)abstract
- Timber footbridges with a span larger than 30 meters are sensitive to vibrations and dynamic factors must therefore be taken into considerations in the design. A case study of a cable-stayed footbridge, Älvsbacka Bridge, with a free span of 130 meters, is presented. The dynamic design of the bridge is compared, based on the old Swedish code, BRO 2004 and the Eurocode 5. Simplified force models presented in BRO 2004 and the ISO 10137 international standard are compared. Vertical and lateral accelerations are measured on the bridge with accelerometers attached to the bridge deck. According to the simplified force model, the vertical acceleration limit was met for a group of twenty pedestrians, which was regarded as a reasonable design situation. From the measured accelerations, the damping factor was calculated as 1.2% of critical damping, which is twice the value used in design.

- Printed electronics are considered for wireless electronic tags and sensors within the future Internet-of-things (IoT) concept. As a consequence of the low charge carrier mobility of present printable organic and inorganic semiconductors, the operational frequency of printed rectifiers is not high enough to enable direct communication and powering between mobile phones and printed e-tags. Here, we report an all-printed diode operating up to 1.6 GHz. The device, based on two stacked layers of Si and NbSi2 particles, is manufactured on a flexible substrate at low temperature and in ambient atmosphere. The high charge carrier mobility of the Si microparticles allows device operation to occur in the charge injection-limited regime. The asymmetry of the oxide layers in the resulting device stack leads to rectification of tunneling current. Printed diodes were combined with antennas and electrochromic displays to form an all-printed e-tag. The harvested signal from a Global System for Mobile Communications mobile phone was used to update the display. Our findings demonstrate a new communication pathway for printed electronics within IoT applications.

- During the Syrian civil war, different types of Salafi-Jihadi rebel groups controlled territory and established governance over civilians. Their governing strategies have been markedly diverse. In this study, we explore how this governance variation can help to explain the occurrence of civil resistance. We suggest that different types of rebel governance structures provide political opportunities for civilians to mobilize against those rebel groups through public demonstrations. In particular, we argue that it is middle-ranged opportunity structures of rebel governance that strongest incentivizes civil resistance, by giving enough space for civilian mobilization but fewer alternative channels of expressing discontent. This argument is explored through an analysis of the variation between the three main Salafi-Jihadi rebel groups in Syria – IS, HTS and Ahrar al-Sham. We show how differences in the groups’ four rebel governance dimensions – rebel collaboration, civilian inclusion, alliance structure, and repression – impact the political opportunities for civilians to mobilize against these groups. We find that HTS, the group that is in the middle range across these four governance dimensions, provided greater opportunity for civilian protests. This study uses a new dataset of civilian resistance events in Syria as well as interviews with civilians governed by these groups.

Rivers of Peace : Institutionalized Mekong River Cooperation and The East Asian Peace

- East Asia represents a remarkable example of a region that has transformed from one of the most violent in the world, in terms of interstate wars and internationalised intrastate conflicts, towards a relatively peaceful region. What explains East Asian peace? This study adopts an institutional perspective, arguing that a crucial role in the creation and development of East Asia’s peace, and in the Mekong region in particular, has been the emergence of transnational river cooperation in the Mekong Basin. It examines the nature and drivers of such institutional cooperation. Explanations can be found in a combination of external support from third parties, and an internal economic growth imperative held by the Mekong states themselves. It provides useful policy lessons for the creation and development of peace and cooperation through institution-building.

Manufacturing Dissent : Modernization and the Onset of Major Nonviolent Resistance Campaigns

- A growing research field examines the conditions under which major nonviolent resistance campaigns—that is, popular nonviolent uprisings for regime or territorial change—are successful. Why these campaigns emerge in the first place is less well understood. We argue that extensive social networks that are economically interdependent with the state make strategic nonviolence more feasible. These networks are larger and more powerful in states whose economies rely upon organized labor. Global quantitative analysis of the onset of violent and nonviolent campaigns from 1960 to 2006 (NAVCO), and major protest events in Africa from 1990 to 2009 (SCAD) shows that the likelihood of nonviolent conflict onset increases with the proportion of manufacturing to gross domestic product. This study points to a link between modernization and social conflict, a link that has been often hypothesized, but, hitherto, unsupported by empirical studies.

Effective field theory analysis of the Coulomb breakup of the one-neutron halo nucleus 19 C

Tidskriftsartikel (refereegranskat)abstract
- We analyse the Coulomb breakup of 19 C measured at 67A MeV at RIKEN. We use the Coulomb-Corrected Eikonal (CCE) approximation to model the reaction and describe the one-neutron halo nucleus 19 C within Halo Effective Field Theory (Halo EFT). At leading order we obtain a fair reproduction of the measured cross section as a function of energy and angle. The description is insensitive to the choice of optical potential, as long as it accurately represents the size of 18 C. It is also insensitive to the interior of the 19 C wave function. Comparison between theory and experiment thus enables us to infer asymptotic properties of the ground state of 19 C: these data put constraints on the one-neutron separation energy of this nucleus and, for a given binding energy, can be used to extract an asymptotic normalisation coefficient (ANC). These results are confirmed by CCE calculations employing next-to-leading order Halo EFT descriptions of 19 C: at this order the results for the Coulomb breakup cross section are completely insensitive to the choice of the regulator. Accordingly, this reaction can be used to constrain the one-neutron separation energy and ANC of 19 C.
