Several proposals have been made during the last ten years on size-independent resonators by using metamaterials for phase compensation. In this paper, we present an estimate of the quality factor of a simple parallel-plate resonator, based on realistic assumptions such as linear, passive, causal, time-translational invariant metamaterials, and lossy walls. It is found that the quality factor of t
To manage risks in Western society is increasingly seen as a process of including the public in different deliberative and/or participatory projects. This is sometimes done via civil society organisations (CSOs) that also have a second role as gatekeepers, managing or constraining flows of knowledge and information. This paper aims to analyse the dual role of CSOs in the management of chemical ris
Simulations of collective effects in the MAX IV 3 GeV ring were done with the tracking code mbtrack. The code is a 6D macroparticle tracking code performing transformations under the influence of various wakefields. Each bunch is presented by a number of macroparticles which are sorted into bins according to their longitudinal position. The discrepancy in the results for the microwave instability
Traditionally the simulation of transient and voltage stability in power systems has been constrained to tools developed specifically for this purpose, e.g. Simpow, PSS/E, ETMSP and Eurostag. While being efficient and thereby able to simulate large systems, their component models are often encapsulated and difficult or impossible to examine and modify. Also, these simulators often require substant
The article concerns artistic development within the context of a Master of Fine Arts program in visual arts in Sweden, and presents an empirical study based on repeated interviews with a group of art students. The aim is to contribute to our present understanding of artistic development by focusing on changes in the relation between the student and his/her artistic work as part of their artistic
