Paula : [Portraits of Paula Beer-Hofmann].
No full textThe name "Paula" is written in gold on the hard cover of this album. The photographs depict Paula Beer-Hofmann as a teenager and in her twenties, dressed in various outfits, sometimes with her hair up, other times with her hair down, sometimes in hats, sometimes with her daughter Miriam. Profile portraits and forward-facing portraits are included. Inscriptions on the photographs note Paula's age and the location, where the photograph was taken, most commonly in Vienna. Some photographs were taken in Atelier d’Ora in Vienna, others by Perscheid in Berlin.The following photographs are included in this album: F 10015, F 10016, F 10017, F 10018, F 10019, F 10020, F 10021, F 10022, F 10023, F 10024, F 10024A, F 10025, F 10026, F 10027, F 10028, F 10029, F 10030, F 10031, F 10032, F 10033, F 10034, F 10035, F 10036, F 10037, F 10038, F 10039, F 10040, F 10041, F 10042Paula (Pauline) Lissy was born in Vienna, Austria in 1879.

Death of Murad Hofmann: Some thoughts and recollections
Get PDFBorn a Catholic in Germany’s Aschaffenburg, Hofmann began his university education at Union College in New York in 1951. Then he studied law at Munich and Harvard Universities with a PhD in jurisprudence from the former in 1957 and a Master of Law from Harvard Law School in 1960. A prolific author of about a dozen books and an eloquent speaker, Hofmann embraced Islam in 1980, performed hajj in 1992 and describes his hajj experiences and his thoughts and reflections on various aspects of Islam in Journey to Makkah
Design, implementation and testing of a real time system to unambiguously assign detected vehicles from car-to-car communication and on-board camera
No full textOn-Board surround sensors, such as cameras and radars, are used in Advanced Driving Assistance Systems applications to improve the driver safety and comfort. In the meantime, Car-to-Car Communication systems are in the deployment phase and have been tested in huge test fields. In order to compensate the weaknesses and benefit from the strengths of both systems, their information can be fused. In this context, one major challenge is the unambiguous assignment of detected vehicles from different sensors, which is still an open research topic and the major target of this work. An innovative algorithm was first tested in Matlab using recorded data and then implemented on real hardware. The results obtained are promising and, from a spatial point of view, they show already a successful matching of vehicles. Compared with the solutions proposed in literature, the developed demonstrator is innovative, and represents the first step towards a real world application running in real time inside cars. Overall, this work is a useful contribution to active safety and autonomous driving applications based on sensor fusion and a good reference for further research on the topic
Propagation of Uncertainty with the Koopman Operator
Get PDFThis paper proposes a new method to propagate uncertainties undergoing nonlinear dynamics using the Koopman Operator (KO). Probability density functions are propagated directly using the Koopman approximation of the solution flow of the system, where the dynamics have been projected on a well-defined set of basis functions. The prediction technique is derived following both the analytical (Galerkin) and numerical (EDMD) derivation of the KO, and a least square reduction algorithm assures the recursivity of the proposed methodology.This is a preprint from Servadio, Simone, Giovanni Lavezzi, Christian Hofmann, Di Wu, and Richard Linares.

In Search of the Worlds of Compliance: Promises and Pitfalls of Quantitative Testing. IHS Political Science Series Paper No. 113, July 2007
Get PDFThe “worlds of compliance” typology as developed by Falkner/Treib/Hartlapp/Leiber (2005) builds on ideal-typical procedural modes of domestic adaptation to EU directives. Recently, the Journal of European Public Policy (JEPP) has published an interesting article discussing this concept. At closer inspection, the analysis presented by Dimiter Toshkov results in some support for, but also some criticism of, the worlds of compliance. His statistics-based approach gives us the opportunity to raise several issues of crucial importance for the entire scholarly community in the field of EU implementation research. Among these are the problem of choosing adequate indicators, of using reliable quantitative data, and of appropriately applying domestic politics approaches and veto player theory. These discussions are of general interest also for a very practical reason: similar methodological choices are rather common in current European integration research
Integrating Drone Truthing and Functional Classification of Remote Sensing Time Series for Supervised Vegetation Mapping
Get PDFAccurate vegetation mapping is essential for monitoring biodiversity and managing habitats, particularly in the context of increasing environmental pressures and conservation needs. Ground truthing plays a crucial role in ensuring the accuracy of supervised remote sensing maps, as it provides the high-quality reference data needed for model training and validation. However, traditional ground truthing methods are labor-intensive, time-consuming and restricted in spatial coverage, posing challenges for large-scale or complex landscapes. The advent of drone technology offers an efficient and cost-effective solution to these limitations, enabling the rapid collection of high-resolution imagery even in remote or inaccessible areas. This study proposes an approach to enhance the efficiency of supervised vegetation mapping in complex landscapes, integrating Multivariate Functional Principal Component Analysis (MFPCA) applied to the Sentinel-2 time series with drone-based ground truthing. Unlike traditional ground truthing activities, drone truthing enabled the generation of large, spatially balanced reference datasets, which are critical for machine learning classification systems. These datasets improved classification accuracy by ensuring a comprehensive representation of vegetation spectral variability, enabling the classifier to identify the key phenological patterns that best characterize and distinguish different vegetation types across the landscape. The proposed methodology achieves a classification accuracy of 92.59%, significantly exceeding the commonly reported thresholds for habitat mapping. This approach, characterized by its efficiency, repeatability and adaptability, aligns seamlessly with key environmental monitoring and conservation policies, such as the Habitats Directive. By integrating advanced remote sensing with drone-based technologies, it offers a scalable and cost-effective solution to the challenges of biodiversity monitoring, enabling timely updates and supporting effective habitat management in diverse and complex environments
