MesSBAR—Multicopter and Instrumentation for Air Quality Research

Air quality measurements usually consist of ground-based instrumentation at fixed locations. However, vertical profiles of pollutants are of interest for understanding processes, distribution, dilution and concentration. Therefore, a multicopter system has been developed to investigate the vertical distribution of the concentration of aerosol particles, black carbon, ozone, nitrogen oxides (NOx) and carbon monoxide and the meteorological parameters of temperature and humidity. This article presents the requirements by different users, the setup of the quadrocopter system, the instrumentation and the results of first applications. The vertical distribution of particulate matter next to a highway was strongly related to atmospheric stratification, with different concentrations below and above the temperature inversion present in the morning. After the qualification phase described in this article, two identically equipped multicopters will be used upwind and downwind of line or diffuse sources such as highways or urban areas to quantify the influence of their emissions on the local air quality.

Emulation in the context of digital art and cultural heritage preservation: Requirements, Approaches and yet so much more to do

Abstract: The article focuses on current approaches and potentials for emulation technologies within the cultural sector. In order to mark the field, practical examples are given. They convey some of the interests of “computer culture enthusiasts”, who engage themselves within cultural production and preservation. In order to sustain their heritage, they have started applying emulation technologies long before traditional institutions. Furthermore, institutionalized interests of cultural memory institutions are explained. Opposed to the enthusiasts’ examples, they focus on the process of value creation within the cultural sector. Opposed to the formerly given examples, this approach is normally centered on (single) “objects” and their specifity, originality, authenticity etc. Coming to a conclusion we ask how far these two seemingly opposing lines might become reconciled. The theory of digital memory seems to be adapted for this alliance and broadens an outlook on future research activities.
