This article analyses the development of integration policies concerning third country nationals at the European level. Starting with the discovery of recent policy developments at the EU level, including new directives granting social rights to non EU citizens, the paper proceeds to examine the reasons that enabled this shift from the national to the European level of decision making. It concludes that integration policies have been created as a new EU policy field amidst the also fairly new policy field of immigration policies. In light of the theoretical concept of „organisational fields” the interests and motives of the main actors involved are analysed, resulting in the following conclusions: First, a European integration policy could only be established within the emerging field of immigration policies. Secondly, the European Parliament, the Council of Europe, several nongovernmental organisations and most notably the European Commission played an important role in promoting integration policies at the European level. Thirdly, these actors tried to strengthen the status of integration policies by emphasising the linkage between successful integration policies and economic and social cohesion.
This thesis is dedicated to models and algorithms for the use in physical cryptanalysis which is a new evolving discipline in implementation security of information systems.
Physical observables such as the power consumption or electromagnetic emanation of a cryptographic module are so-called `side channels'. They contain exploitable information about internal states of an implementation at runtime. Physical effects can also be used for the injection of faults. Fault injection is successful if it recovers internal states by examining the effects of an erroneous state propagating through the computation.
The best currently known approach in physical cryptanalysis is a thorough experimental verification at a profiling stage, which is included in methods achieving maximum power. The final multivariate algorithms of this thesis can be seen as the most efficient ones in side channel cryptanalysis.

Early Detection of UV-B Induced Damages on Apple Seedlings by Fluorescence and Reflection Techniques
(2007)
This paper addresses the urgent need for international standardization of Context Metadata for e-Learning environments. In particular, E-Learning when distributed over the Internet, can synchronously and asynchronously reach a huge number of learners but also has to deal with a variety of different cultures and societies and the related complications. A lot of the differences strongly demand adaptation processes in which especially the contents are being modified to fit the needs in the targeted contexts. In our approach solving this task, we determined a list of around 160 significant possible differences and defined those as context metadata. In this paper, we show the results of our research regarding to the determination of context related influence factors as well as approaches to deal with them and present a first specification of the representing context-metadata.
This paper addresses the problem of adaptation of E-Learning to a given or proposed context. Current learning technology standards are available for various purposes, such as contents, learner profiles or learning activities, but there are no specifications to describe the context of learning scenarios. Such a description is crucial to identify change-requirements or to compare situations when learning scenarios are re-used. In this paper, we define a specification of context metadata. We show how they can be used to adapt learning scenarios from a given to a new context, in particular to identify change requirements for the internationalization of learning scenarios.

Reliable multicast transport services for content delivery in heterogeneous mobile environment
(2007)
For efficient deployment of new reliable multicast applications in heterogeneous mobile Internet environments, appropriate retransmission strategies are proposed. The focus is the minimization of the protocol overhead for reliable transport taking into account behaviour in mobile networks (oss and handover behaviour) and application requirements (such as carousel file transfer, one-to-many download and media streaming combined with recording). The proposed techniques are designed as building blocks for localized multicast error control supported by access routers. Considering IETF RMT standardization work, the discussed retransmission approaches can be used for flexible configuration of tree-based reliable multicast protocols in converged wired and wireless Internet environment. The implementation developed for the European project DAIDALOS [1] is based on Linux IPv6 environment. Simulations in ns2 focusing on the benefits of the proposed multicast retransmission schemes for particular application scenarios are presented.
Structural and Dynamical Properties of Polystyrene Determined by Coarse-Graining MD Simulations
(2007)
We present results from a detailed study of a new, optimized coarse-grained (CG) model of polystyrene (PS) and compare it with a recently published one (Harmandaris et al., Macromolecules 2006, 39, 6708). We will explain in detail, what led us to a different mapping scheme and put that into the general framework, with special emphasis on the aspect of time mapping. The new model is tested against the structural and dynamic properties of PS, resulting from atomistic simulations.
