Konstruktion und Concetto. Die römischen Katafalke für Kardinal Alessandro Farnese (1589), Papst Sixtus V. (1591) und Principe Carlo Barberini (1630)

In Rom entstand im ausgehenden 16. Jahrhundert die Gattung des „Tempietto-Katafalks“, eines Trauergerüsts in Form eines überkuppelten Zentralbaus, der anlässlich der feierlichen Exequien eines hochrangigen Verstorbenen die symbolische Totenbahre als anspruchsvolle ephemere Kleinarchitektur überfängt. Anhand dreier herausragender Beispiele, der Katafalke für Kardinal Alessandro Farnese, Papst Sixtus V. und Principe Carlo Barberini, sollen die architektonische Gestalt der Funeraltempietti und ihre symbolische Aussage näher beleuchtet werden. Dabei soll weniger die Ikonographie der figürlichen Ausstattung im Mittelpunkt stehen als vielmehr die “Sprachfähigkeit” der gewählten architektonischen Formen, die bei den hier vorgestellten römischen Katafalken ein zentraler Teil der Gesamtkonzepts ist. Dabei sind sowohl der Festanlass – die Memoria des verstorbenen Würdenträgers – als auch die Architektur selbst zum Thema gemacht.

The Samoa Hurricane, 15-16 March 1889

Analysing historical weather extremes such as the tropical cyclone in Samoa in March 1889 could add to our understanding of extreme events. However, up to now the availability of suitable data was limiting the analysis of historical extremes, particularly in remote regions. The new “Twentieth Century Reanalysis” (20CR), which provides six-hourly, three-dimensional data for the entire globe back to 1871, might provide the means to study this and other early events. While its suitability for studying historical extremes has been analysed for events in the northern extratropics (see other papers in this volume), the representation of tropical cyclones, especially in early times, remains unknown. The aim of this paper is to study to the hurricane that struck Samoa on 15-16 March 1889. We analyse the event in 20CR as well as in contemporary observations. We find that the event is not reproduced in the ensemble mean of 20CR, nor is it within the ensemble spread. We argue that this is due to the paucity of data assimilated into 20CR. A preliminary compilation of historical observations from ships for that period, in contrast, provides a relatively consistent picture of the event. This shows that more observations would be available and implies that future versions of surface-based reanalyses might profit from digitizing further observations in the tropical region.

BENCHMARKING AND IMPLEMENTATION OF A NEW INDEPENDENT MONTE CARLO DOSE CALCULATION QUALITY ASSURANCE AUDIT TOOL FOR CLINICAL TRIALS

Introduction Commercial treatment planning systems employ a variety of dose calculation algorithms to plan and predict the dose distributions a patient receives during external beam radiation therapy. Traditionally, the Radiological Physics Center has relied on measurements to assure that institutions participating in the National Cancer Institute sponsored clinical trials administer radiation in doses that are clinically comparable to those of other participating institutions. To complement the effort of the RPC, an independent dose calculation tool needs to be developed that will enable a generic method to determine patient dose distributions in three dimensions and to perform retrospective analysis of radiation delivered to patients who enrolled in past clinical trials. Methods A multi-source model representing output for Varian 6 MV and 10 MV photon beams was developed and evaluated. The Monte Carlo algorithm, know as the Dose Planning Method (DPM), was used to perform the dose calculations. The dose calculations were compared to measurements made in a water phantom and in anthropomorphic phantoms. Intensity modulated radiation therapy and stereotactic body radiation therapy techniques were used with the anthropomorphic phantoms. Finally, past patient treatment plans were selected and recalculated using DPM and contrasted against a commercial dose calculation algorithm. Results The multi-source model was validated for the Varian 6 MV and 10 MV photon beams. The benchmark evaluations demonstrated the ability of the model to accurately calculate dose for the Varian 6 MV and the Varian 10 MV source models. The patient calculations proved that the model was reproducible in determining dose under similar conditions described by the benchmark tests. Conclusions The dose calculation tool that relied on a multi-source model approach and used the DPM code to calculate dose was developed, validated, and benchmarked for the Varian 6 MV and 10 MV photon beams. Several patient dose distributions were contrasted against a commercial algorithm to provide a proof of principal to use as an application in monitoring clinical trial activity.

Why Monte Carlo Simulations are Inferences and not Experiments

Monte Carlo simulations arrive at their results by introducing randomness, sometimes derived from a physical randomizing device. Nonetheless, we argue, they open no new epistemic channels beyond that already employed by traditional simulations: the inference by ordinary argumentation of conclusions from assumptions built into the simulations. We show that Monte Carlo simulations cannot produce knowledge other than by inference, and that they resemble other computer simulations in the manner in which they derive their conclusions. Simple examples of Monte Carlo simulations are analysed to identify the underlying inferences.

More than just Good Luck. How to Explain the Success of Monte Carlo Simulations

Monte Carlo simulation is a powerful method in many natural and social sciences. But what sort of method is it? And where does its power come from? Are Monte Carlo simulations experiments, theories or something else? The aim of this talk is to answer these questions and to explain the power of Monte Carlo simulations. I provide a classification of Monte Carlo techniques and defend the claim that Monte Carlo simulation is a sort of inference.

Ein Forschungsreisender als Notbehelf: Hermann von Wissmann und der erste Überseeeinsatz des Deutschen Reichs (1889-1891)

When the German government faced for the first time an irregular war in German East Africa in 1888, it realised that it did not have the necessary means for such a conflict. Hermann Wissmann, an explorer, was therefore given the mandate to form and lead a force of mercenaries that was bound to him personally on the basis of contracts. Although Wissmann was successful in crushing the disturbances, the government of the Reich refused to give him a leading administrative position in the new formed protectorate subordinate directly to the Kaiser. It feared that the entrepreneur of violence, which had up to then been backed up, would not accept the regulations of colonial rule that should be implemented. Soon, however, it became clear that due to entrenched local views on sovereignty and legitimacy it would be difficult to transfer the western European concept of the monopoly of the state on violence to Africa.
