Advanced methods for safe visualization on automotive displays

Camera Monitor Systems (CMSs), for example, for backup cameras or mirror replacements, become increasingly important and already cover safety aspects such as guaranteed latency and no frame freeze. Today\u27s approaches deal only with supervision of the digital interface, LCD backlight, and power supply. This paper introduces methods for advanced safety monitoring of panel electronics and optical display output that aim to enable future CMS based automotive use cases. Our methods are based on correlation of physical measurements with predicted values derived from a corresponding display model. This model was made via calibration measurements and many test patterns. Correlation of the monitoring results with predicted values corresponds to the probability that the RGB data are shown as intended. This implies that an overlying system, an Automotive Safety Integrity Level (ASIL) Prepared Video Safety System (APVSS), ensures that only safety verified RGB data are provided to the panel electronics. In case of failures, our methods enable a safe system state, for example, by deactivating the panel. An additional challenge is to allow graceful degradations, a safe but slightly degraded image may provide a better customer experience compared with no information. We successfully verified our approach by a fully functional prototype and extensive evaluation towards “light-to-light” (camera to display output) supervision

Transferring and implementing the general dynamic model of oceanic island biogeography at the scale of island fragments: the roles of geological age and topography in plant diversification in the Canaries

Aim The general dynamic model (GDM) of oceanic island biogeography integrates rates of immigration, speciation and extinction in relation to a humped trajectory of island area, species carrying capacity and topographic complexity through time, based on a simplified island ontogeny. In practice, many islands have more complex ontogenies, featuring surfaces of varying age. Here, we extend the GDM to apply at a local scale within islands, and test the predictions analytically within individual islands. Location El Hierro, La Palma and Tenerife (Canary Islands). Methods Following the GDM logic, we derive predictions for the distributions and richness of single island endemics (SIEs) across island landscapes of different age. We test these predictions by means of generalized linear models and binominal tests using gridded species occurrence data for vascular plant SIE species and a set of climatic, topographic and terrain age variables. We also examined phylogenetic divergence times for a subset of endemic lineages. Results Geological age, in interaction with slope, and topographic variables, best explained SIE richness at the landscape scale. About 70% of SIEs had ranges strongly biased to, or largely restricted to old terrain. Available phylogenetic divergence times of SIEs of radiated plant lineages suggested an origin on the older parts of the islands. Metrics of anthropogenic disturbance and habitat availability were unrelated to the observed SIE pattern. Main conclusions Our findings support the hypothesis that SIEs have evolved and accumulated on older and topographically complex terrain, while colonization processes predominate on the youngest parts. These results imply that evolutionary processes shape species distributions at the landscape scale within islands. This opens the perspective of extending the GDM framework to understand processes at a local scale within individual islands

Evolutionary winners are ecological losers among oceanic island plants

Aim Adaptive radiation, in which successful lineages proliferate by exploiting untapped niche space, provides a popular but potentially misleading characterization of evolution on oceanic islands. Here we analyse the respective roles of members of in situ diversified vs. non-diversified lineages in shaping the main ecosystems of an archipelago to explore the relationship between evolutionary and ecological ‘success’. Location Canary Islands. Taxon Vascular plants. Methods We quantified the abundance/rarity of the native flora according to the geographical range (number of islands where present and geographical extent of the range), habitat breadth (climatic niche) and local abundance (cover) using species distribution data based on 500 × 500 m grid cells and 2000 vegetation inventories located all over the archipelago. Results Species of diversified lineages have significantly smaller geographic ranges, narrower climatic niches and lower local abundances than those of non-diversified lineages. Species rarity increased with the degree of diversification. The diversified Canarian flora is mainly comprised by shrubs. At both archipelagic and island level, the four core ecosystems (Euphorbia scrub, thermophilous woodlands, laurel forest and pine forest) were dominated by non-diversified lineages species, with diversified lineages species providing <25% cover. Species of diversified lineages, although constituting 54% of the archipelagic native flora, were only abundant in two rare ecosystems: high mountain scrub and rock communities. Main conclusions Radiated species, endemic products of in situ speciation, are mostly rare in all three rarity axes and typically do not play an important role in structuring plant communities on the Canaries. The vegetation of the major ecosystem types is dominated by plants representing non-diversified lineages (species that derive from immigration and accumulation), while species of evolutionarily successful lineages are abundant only in marginal habitats and could, therefore, be considered ecological losers. Within this particular oceanic archipelago, and we posit within at least some others, evolutionary success in plants is accomplished predominantly at the margins.publishedVersio

Vocalizing the Angels of Mons: Audio Dramas as Propaganda in the Great War of 1914 to 1918 Societies 2014, 4(2), 180-221; doi:10.3390/soc4020180

Sound drama production prior to the onset of the “Radio Age” underwent a pioneering development during the Great War. This was achieved by the making, publication and distribution of short audio dramas acted with sound effects and music in front of early microphones and released in the form of 78 rpm phonograph discs. Entertaining storytelling through dramatic performance was mobilized for the purposes of improving recruitment and disseminating patriotic endorsement recordings. This article focuses on the sound dramatization of the myth of “The Angels of Mons” released by Regal in 1915. The recording is examined as a text for its significance in terms of propaganda, style of audio-drama, and any cultural role it may have played in the media of the First World War. The Regal disc was an example of what was described at the time as “descriptive sketches.” This article explores why a sound phonograph was used to dramatize the myth that angels intervened to assist the British Expeditionary Force to resist the German Army invading France through Belgium in 1914. A number of historians have discussed the First World War as being a theatre for the first modern media war, in which the process of propaganda was modernized. To what extent does “The Angels of Mons” phonograph and the genre of descriptive sketches support this analysis? Does this short sound drama play have any relevance to the cultural phenomena of spiritualism, modernism and patriotic Christianity identified as being important during the Great War period

Didyma, Türkei. Site Management und Tempelkonsolidierung. Die Arbeiten der Jahre 2017 und 2018

The Site Management Project, which based on a concept developed in 2012/2013, pursues two main objectives: to provide visitors access to the excavation area of the Sacred Way, and to establish a connection with the separated area of the Apollo Temple by means of a new visitor guidance system. As in previous years consolidation work on the Apollo Temple has been done in accordance with international standards. The completion of the examination of the temple but also a mapping of the damages and consolidation work already undertaken since 1992 constituted additional measures in 2018. Another task was to determine and to visualize all the rebuilt parts, carried out during the excavation of the temple at the beginning of the 20th century
