Inner point methods: On necessary optimality conditions of various reformulations of a constrained optimization problem

Marco Rozgic, Manuel Jaraczewski & Marcus Stiemer
Primal-dual inner point algorithms are known to be efficient in solving non-linear constrained optimization problems. Modern implementations are capable of solving optimization problems with a huge number of non-linear constraints. To do this efficiently it is crucial, that necessary optimality conditions are formulated such that they can be easily implemented into a computer program. Favourable is a formulation as a system of equations that can be linearized. The Karush-Kuhn-Tucker conditions represent such a set. This...

Dataset of air ion and aerosol measurements. Tahkuse 2004-2014

Urmas Hõrrak, Hilja Iher, Kaupo Komsaare, Eduard Tamm & Hannes Tammet
The present dataset of air ion mobility and aerosol particle size distributions is a follow-up of the dataset Tahkuse_1993_1994, http://datadoi.ut.ee/handle/33/22. It makes available results of routine measurements in Tahkuse Air Monitoring Station from 01.01.2004 to 31.12.2014. The station is located in the Sepa farmhouse in Tahkuse village about 27 km northeast of the city of Pärnu, Estonia. Geographical coordinates are 58º31'28"N, 24º55'32"E, 24 m a.s.l. The farmhouse is surrounded with flat open landscape with some...

Data from: Determining spatio-temporal metrics that distinguish play outcomes in field hockey

Ciarán McInerney
Tactical behaviour in field sports can be examined using spatio-temporal metrics, that is, descriptions of player behaviour derived from data of player positions over time. Methods typically used by sports performance analysts cannot appropriately analyse the many spatio-temporal metrics and their interactions. The interactions between theses descriptions of player behaviour could potentially describe tactical differences in performance. The aim of this thesis was to determine which spatio-temporal metrics distinguish play outcomes in field hockey. The...

DynVolc Database

Lucia Gurioli & Andrea Di Muro
Observation system within France’s National Service for Volcanological Observation (SNOV).The system contributes complete, integrated, data sets for eruptive products from : field studies (i.e., field mapping, outcrop and sample descriptions), textural analysis (i.e., particle size and size distribution, morphology, density, porosity, connectivity, permeability and vesicle and crystal size, distribution, shape and orientation),and chemical data (i.e., bulk and glass chemistry).

L’ambito delle Scienze integrate. Il PAS A059 - Matematica e Scienze nella scuola secondaria di primo grado e il PAS A060 - Scienze naturali, Chimica e Geografia, Microbiologia

Michele Stoppa & Patrizia Nitti
Dopo una sintetica premessa dedicata all’insegnamento integrato delle Scienze nelle Scuole secondarie di primo e secondo grado e alle sue criticità, vengono illustrate le peculiarità del PAS A059 - con precipuo riferimento all’Area delle Scienze - e del PAS A060, con particolare attenzione agli aspetti attinenti l’offerta formativa, le metodologie didattiche adottate e gli esiti dell’esperienza formativa.

Die Rolle von Persönlichkeit bei der Inneren Kündigung im Bezug zu den Prädiktoren Psychologischer Vertrag und Sensibilität für Ungerechtigkeit

Achim Wortmann
Das Phänomen Innere Kündigung stellt wissenschaftliche Untersuchungen ebenso wie die unternehmerische Praxis noch immer vor große Herausforderungen. Der bisherige Umgang damit ist geprägt von individualen Betrachtungen, die die Auswirkungen der Interaktion von Person-Gruppe-Organisation nicht gerecht werden. Ein zentraler Bestandteil des Verständnisses von Innerer Kündigung basiert auf einer unzureichenden empirischen Studie, die kaum Aussagekraft hat. Darüber hinaus gibt es nur wenig brauchbare Daten. Diese Lücke wird mit der vorliegenden Arbeit geschlossen. In einer umfangreichen Befragung von...

Spiders of Europe

Daniel Gloor, Theo Blick, Wolfgang Nentwig, Christian Kropf & Ambros Hänggi
By mid of 2010 this database contains information on more than 3900 European spider species from 58 families with more than 16.000 figures, 3900 distribution maps, and 600 publications. This makes Spiders of Europe to one of the largest Internet identification keys and we hope that all users of this project further contribute to it.

Variational Space-Time Methods for the Elastic Wave Equation and the Diffusion Equation

Uwe Köcher
In dieser Arbeit werden variationelle Raum-Zeit Diskretisierungen für eine präzise und zuverlässige numerische Approximation von drei-dimensionalen elastischen Ultraschallwellen in Festkörperstrukturen analysiert. Eine mögliche Anwendung ist die numerische Simulation von Strukturüberwachungssystemen für moderne Faserverbund-Werkstoffe. Für die räumliche Diskretisierung wird eine unstetige (discontinuous) Galerkin Methode im Sinne einer unstetigen Finite Elemente Methode mit beliebigen Polynomgrad angewandt. Für die zeitliche Diskretisierung werden unstetige, stetige sowie stetig differenzierbare Galerkin Methoden im Sinne von Zeitschrittverfahren angewandt und diskutiert. Analysiert werden...

Lokale Entropieproduktionsraten in der Polymerelektrolyt-Membran-Brennstoffzelle

Marc Siemer
Die Energiewandlung in einer Brennstoffzelle ist im Gegensatz zur Wandlung in einer Wärmekraftmaschine nicht schon prinzipiell durch den Carnot-Wirkungsgrad begrenzt. Theoretisch ist es daher möglich, die Brennstoffenergie verlustfrei in elektrischen Strom zu wandeln, wodurch die Brennstoffzellentechnologie thermodynamisch sehr interessant erscheint. - Reale Brennstoffzellen weisen im Betrieb jedoch nicht unerhebliche Verluste auf, so dass ca. 30% - 50% der mit dem Brennstoff zugeführten Energie als Abwärme von dem System abgegeben werden. - In dieser Arbeit wurden...
