This contribution examines adolescent language use, interaction, and acts of identification on social media sites. Our approach is sociolinguistic, and we show how the understanding of language users today needs to break free from previously well-established sociolinguistic notions such as languages as countable units. In the following we argue that hybridity in language use is not intrinsically deviant, that language users may have multiple belongings and identifications, and that linguistic ideology must be accounted for by researchers. We also demonstrate how notions such as registers, polycentricity, and (poly)languaging enable us to address the relationships between language users, language form, social goals, and normativity. The data come from three linguistically heterogeneous European settings, and all focus on hybridity and ethnicity. [less ▲]

Software development for robots is a knowledge intensive exercise. To capture this knowledge explicitly and formally in the form of various domain models, roboticists have recently employed model-driven engineering (MDE) approaches. However, these models are merely seen as a way to support humans during the robot's software design process. We argue that the robots themselves should be first-class consumers of this knowledge to autonomously adapt their software to the various and changing run-time requirements induced, for instance, by the robot's tasks or environment. Motivated by knowledge-enabled approaches, we address this problem by employing a graph-based knowledge representation that allows us not only to persistently store domain models, but also to formulate powerful queries for the sake of run time adaptation. We have evaluated our approach in an integrated, real-world system using the neo4j graph database and we report some lessons learned. Further, we show that the graph database imposes only little overhead on the system's overall performance. [less ▲]

In the current thesis the model of the ROS management network is built using the domino principle. The model offers insight into the design principles underlying the ROS management network and enlightens its functionality in the diseases such as cancer and Parkinson’s disease (PD). It is validated using experimental data. The model is used for in silico study of the ROS management dynamics under the stress conditions (oxidative stress). This highlights the phenomena of both adaptation to stress and the stress accumulation effect in case of repeated stress. This study also helps to discover the potential ways to a personalized treatment of the insufficient ROS management. The different ways of a control of the ROS management network are shown using the optimal control approach. Obtained results could be used for a seeking of the treatment strategies to fix the ROS management failures caused by an oxidative stress, neurodegenerative diseases, etc. Or, in vice versa, to develop the ways of a controllable cell death that might be used in cancer research.

Functional encryption (FE) allows an authority to issue tokens associated with various functions, allowing the holder of some token for function f to learn only f(D) from a ciphertext that encrypts D. The standard approach is to model f as a circuit, which yields inefficient evaluations over large inputs. Here, we propose a new primitive that we call updatable functional encryption (UFE), where instead of circuits we deal with RAM programs, which are closer to how programs are expressed in von Neumann architecture. We impose strict efficiency constrains in that the run-time of a token P' on ciphertext CT is proportional to the run-time of its clear-form counterpart (program P on memory D) up to a polylogarithmic factor in the size of D, and we envision tokens that are capable to update the ciphertext, over which other tokens can be subsequently executed. We define a security notion for our primitive and propose a candidate construction from obfuscation, which serves as a starting point towards the realization of other schemes and contributes to the study on how to compute RAM programs over public-key encrypted data.

We present, for the first time, a general strategy for designing ARX symmetric-key primitives with provable resistance against single-trail differential and linear cryptanalysis. The latter has been a long standing open problem in the area of ARX design. The Wide-Trail design Strategy (WTS), that is at the basis of many S-box based ciphers, including the AES, is not suitable for ARX designs due to the lack of S-boxes in the latter. In this paper we address the mentioned limitation by proposing the Long-Trail design Strategy (LTS) -- a dual of the WTS that is applicable (but not limited) to ARX constructions. In contrast to the WTS, that prescribes the use of small and efficient S-boxes at the expense of heavy linear layers with strong mixing properties, the LTS advocates the use of large (ARX-based) S-Boxes together with sparse linear layers. With the help of the so-called long-trail argument, a designer can bound the maximum differential and linear probabilities for any number of rounds of a cipher built according to the LTS. To illustrate the effectiveness of the new strategy, we propose Sparx -- a family of ARX-based block ciphers designed according to the LTS. Sparx has 32-bit ARX-based S-boxes and has provable bounds against differential and linear cryptanalysis. In addition, Sparx is very efficient on a number of embedded platforms. Its optimized software implementation ranks in the top-6 of the most software-efficient ciphers along with Simon, Speck, Chaskey, LEA and RECTANGLE. As a second contribution we propose another strategy for designing ARX ciphers with provable properties, that is completely independent of the LTS. It is motivated by a challenge proposed earlier by Wallen and uses the differential properties of modular addition to minimize the maximum differential probability across multiple rounds of a cipher. A new primitive, called LAX is designed following those principles. LAX partly solves the Wallen challenge. [less ▲]

Die vorliegende Studie zur Situation der Jugendlichen in der Gemeinde Strassen wurde von der Forschergruppe „youth research“ an der Forschungseinheit INSIDE (Integrative Research Unit on Social and Individual Development) der Universität Luxemburg im Auftrag des Bürgermeister- und Schöffenrates der Gemeinde Strassen erstellt. Diese Studie ist Teil des Jugendkommunalplans für die Gemeinde Strassen und hat zum Ziel, den Verantwortlichen in Politik, Verwaltung und Jugendarbeit Informationen zu liefern, die zu einem besseren Verständnis der Jugendlichen in der Gemeinde beitragen. Denn die Gruppe der Jugendlichen repräsentiert mit ihren Wünschen, eigenen Sichtweisen und Erwartungen eine zentrale Entwicklungsperspektive für die Gemeinde Strassen. Unter anderem aus diesem Grund sind die Ergebnisse dieser Studie eine wichtige Informations- und Diskussionsgrundlage für die zukünftige Planung und Umsetzung der kommunalen Jugendpolitik und ein wichtiges Fundament für „Evidence-based-policy-making“, also eine wissensbasierte Jugendpolitik in Strassen. Diesem Anliegen entsprechend wurde diese Studie als Situations- und Bedarfsanalyse konzipiert. Wichtige thematische Aspekte sind insbesondere die Lebenswelten, das Freizeitverhalten und die Freizeitinteressen der Jugendlichen in Straßen aber auch die sozialen Herkunftsmilieus die einen starken Einfluss auf die Startbedingungen, Lebensentwürfe und Zukunftsperspektiven der Jugendlichen haben. Nicht zuletzt interessiert auch die Frage, wie die Jugendlichen unterschiedlicher Herkunft in der Gemeinde integriert sind, wie zufrieden sie mit den Angeboten und der Infrastruktur sind, welche Möglichkeiten der Partizipation für sie wichtig sind und inwiefern die Maßnahmen und Angebote der kommunalen Politik die Jugendlichen erreichen. In diesem Zusammenhang ist auch ein genauerer Blick auf die Situation der Jugendlichen mit einer ausländischen Nationalität von Interesse, zum Beispiel die Frage, wo Defizite aber auch Chancen einer stärkeren Integration oder Beteiligung dieser großen Zahl an Jugendlichen am Gemeindeleben bestehen. Bei vielen Themenbereichen sind Vergleiche mit anderen luxemburgischen oder mit internationalen Jugendstudien möglich. Dadurch können Gemeinsamkeiten sowie Besonderheiten der Gemeinde Straßen deutlich gemacht werden. [less ▲]

Due to its relevancy to point scoring, the spike is considered as one of the most important skills in fistball. Biomechanical analyses of this sport are very rare. In the present study, we performed a three-dimensional kinematic analysis of the fistball spike, which helps to specify performance parameters on a descriptive level. Recorded by four synchronized cameras (120 Hz) and linked to the motion capture software Simi Motion® 5.0, three female fistball players of the second German league (24–26 years, 1.63–1.69 m) performed several spikes under standardized conditions. Results show that the segment velocities of the arm reached their maximum successively from proximal to distal, following the principle of temporal coordination of single impulses. The wrist shows maximum speed when the fist hits the ball. The elbow joint angle performs a rapid transition from a strong flexion to a (almost) full extension; however, the extension is completed after the moment of ball impact. In contrast, the shoulder joint angle increases almost linearly until the fistball contact and decreases afterward. The findings can be used to optimize the training of the spike. [less ▲]

The real estate project KONS encountered a two and a half year process of demolition of an existing building and construction of a new building complex in a central, urban location of Luxembourg City opposite of the main railway station. Thereby the ambitious specifications of the investor as well as the requirements of the local authorities could be met only through a comprehensive and intelligent planning process. The complex interrelation between logistics and construction management processes, detailing and overall economic assessment found the solution of steel-composite design highly performant and efficient in every aspect.

This paper investigates the problem of the interference among multiple simultaneous transmissions in the downlink channel of a multi-antenna wireless system. A symbol-level precoding scheme is considered, where the data information is used, along with the channel state information, in order to exploit the multi-user interference and transform it into useful power at the receiver side. In this framework, it is important to consider the power limitations individually for each transmitting antenna, since a common practice in multi-antenna systems is the use of separate per-antenna amplifiers. Thus, herein the problem of per-antenna power minimization in symbol-level precoding is formulated and solved, under Quality-of-Service constraints. In the proposed approach, the precoding design is optimized in order to control the instantaneous power transmitted by the antennas, and more specifically to limit the power peaks, while guaranteeing some specific target signal-to-noise ratios at the receivers. Numerical results are presented to show the effectiveness of the proposed scheme, which outperforms the existing state of the art techniques in terms of reduction of the power peaks and of the peak-to-average power ratio across the transmitting antennas.
