Mit großen Kameras, einem Zelt als Dunkelkammer und zahllosen sperrigen Gerätschaften tourte Andreas Groll (1812-1872) per Kutsche, Bahn oder Donauschiff durch die Monarchie, um für seine nicht weniger innovativen Auftraggeber Fotografien nach Hause zu bringen. Diese ersetzten nicht einfach Bilder in traditionellen Medien, sondern revolutionierten durch ihre als untrüglich angesehene Glaubwürdigkeit den Gebrauch visueller Dokumente an sich. Denkmalpfleger trugen mit ihrer Hilfe Archive alter Bauwerke zusammen, Architekten häuften zahllose Vorbilder an, und der aufblühenden Industrie dienten sie als authentischen Beleg ihrer Leistungsfähigkeit. Der Wiener erfand damit zwischen Prag und Graz, Salzburg und Krakau, Südböhmen und dem fernen Banat als erster den Beruf des modernen Fotografen. Die vorliegende Publikation und die sie begleitenden Ausstellungen versuchen, den wenig dokumentierten Lebensweg dieser Ausnahmefigur der österreichischen Fotografie der Frühzeit zu rekonstruieren und zugleich Aufschluss zu geben über das Umfeld, in dem die erstaunliche Karriere des Andreas Groll möglich wurde.…

Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -A regression analysis describes the dependency of random variables in the form of a functional relationship. One distinguishes between the dependent response variable and one or more independent influence variables. There is a variety of model classes and inference methods available, ranging from the conventional linear regression model up to recent non- and semiparametric regression models. The so-called generalized regression models form amethodically consistent framework incorporating many regression approaches with response variables that are not necessarily normally distributed, including the conventional linear regression model based on the normal distribution assumption as a special case. When repeated measurements are modeled in addition to fixed effects also random effects or coefficients can be included. Such models are known as Random Effects Models or Mixed Models. As a consequence, regression procedures are applicable extremely versatile and consider very different problems. In this dissertation regularization techniques for generalized mixed models are developed that are able to perform variable selection. These techniques are especially appropriate when many potential influence variables are present and existing approaches tend to fail. First of all a componentwise boosting technique for generalized linear mixed models is presented which is based on the likelihood function and works by iteratively fitting the residuals using weak learners. The complexity of the resulting estimator is determined by information criteria. For the estimation of variance components two approaches are considered, an estimator resulting from maximizing the profile likelihood, and an estimator which can be calculated using an approximative EM-algorithm. Then the boosting concept is extended to mixed models with ordinal response variables. Two different types of ordered models are considered, the threshold model, also known as cumulative model, and the sequential model. Both are based on the assumption that the observed response variable results from a categorized version of a latent metric variable. In the further course of the thesis the boosting approach is extended to additive predictors. The unknown functions to be estimated are expanded in B-spline basis functions, whose smoothness is controlled by penalty terms. Finally, a suitable L1-regularization technique for generalized linear models is presented, which is based on a combination of Fisher scoring and gradient optimization. Extensive simulation studies and numerous applications illustrate the competitiveness of the methods constructed in this thesis compared to conventional approaches. For the calculation of standard errors bootstrap methods are used. 176 pp. Englisch.…

Wien, undated ( before 1869 ), the 8 albumine prints are mounted on 6 boards. The albumine prints represent different views of the original drawings by von Sicardsburg and van der Nüll. Sizes vary between 26 x 38 cm and 50 x 20 cm. Some of the drawings are titled. E.g. ''Rückwärtige Ausicht'' on board n°6. (This is also the print with Groll's name). Other drawings are: Groundfloor, Querschnitt durch die Bühne, Querschnitt, Seitenansicht (aussen). .All prints are mounted on contemporary boards. (62 x 46 cm). The boards are a bit dustsoiled, some of the prints are more or less faded. The boards are stamped with the collection stamp of Frans Baeckelmans ( 1835 - 1896) . He was an Antwerp (Belgium - Flanders) architect who reputedly designed neo-renaissance buildings partially based on photographic examples of classical renaissance buildings ( e.g. the old court of justice in Antwerp, based on a Baldus picture of the Louvre - this picture also formed part of his collection). The photographer Andreas Groll ( 1812 - 1872) was one of the photography pioneers of the Habsburg empire. Architecture was one of his main intrests. The Wiener Staatsoper ( still standing) was contructed between 1861 and 1869 at the newly constructed Ringstrasse. Its neo-renaissance style must surely greatly have pleased the Antwerp architect collector . This collection is an interesting and early testimony of the use of the newly invention of the art of photography in architectural design.…
