Interconnected vehicles are a growing commodity providing remote access to on-board systems for monitoring and controlling the state of the vehicle. Such features are built to facilitate and strengthen the owner’s knowledge about its car but at the same time they impact its safety and security. Vehicles are not ready to be fully connected as various attacks are currently possible against their control systems. In this paper, we analyse possible attack scenarios on a recently released all-electric car and investigate their impact on real life driving scenarios. We leverage our findings to change the behaviour of safety critical components of the vehicle in order to achieve autonomous driving using an Open Vehicle Monitoring System. Furthermore, to demonstrate the potential of our setup, we developed a novel mobile application able to control such vehicle systems remotely through the Internet. We challenge the current state-of-the-art technology in today’s vehicles and provide a vulnerability analysis on modern embedded systems. [less ▲]

Despite the deleterious effect of hardware impairments on communication systems, most prior works have not investigated their impact on widely used relay systems. Most importantly, the application of inexpensive transceivers, being prone to hardware impairments, is the most cost-efficient way for the implementation of massive multiple-input multiple-output (MIMO) systems. Consequently, the direction of this paper is towards the investigation of the impact of hardware impairments on MIMO relay networks with large number of antennas. Specifically, we obtain the general expression for the ergodic capacity of dual-hop (DH) amplify-and-forward (AF) relay systems. Next, given the advantages of the free probability (FP) theory with comparison to other known techniques in the area of large random matrix theory, we pursue a large limit analysis in terms of number of antennas and users by shedding light to the behavior of relay systems inflicted by hardware impairments.

FULL TEXT Before 1848 only few choirs existed in Luxembourg: “Les Villageois” in Contern (1825), the parish choir of Echternach (1834) and the Société d’amateurs de chant (also known under the German name of Liedertafel in Luxembourg City (1843). In 1848, the Dutch King William II (who was also Grand-Duke of Luxembourg) proclaimed, under the pressure of the European wave of democratic revolts, a more liberal constitution, which conferred the right of association. As a result, amateur ensembles began to emerge all over the Grand-Duchy. During the following five years about ten choral societies were founded – a large number for a small country. Wind bands and gymnastic clubs also proliferated. The main objective of these societies was to engage in cultural-collective leisure pursuits; no professionalization was involved (to this day, Luxembourg still lacks a professional choir.) At this early stage, choirs were men-ony. They followed the German model of Zelter’s (Berlin) and Silcher’s singing societies (“Liedertafel”). The repertoire consisted at this initial phase of four-part songs of German Romanticism. Later on, Luxembourg composers like Jean-Antoine Zinnen (1827-1898), Laurent Menager (1835-1902) and their successors Gustave Kahnt (1848-1923) and Alfred Kowalsky (1879-1943) furnished local compositions. Analogous to these secular societies were the church choirs, one of the first being in 1844 the Caecilian association (Cäcilienverein) of St. Peter, today Notre-Dame cathedral in Luxembourg City. (Luxembourg became an independent diocese in 1870.) It introduced the tradition of the German Cecilian movement to the Grand-Duchy. A first wind band and choir competition was organized in 1852; eight choral societies participated. In the following years, the demand for competitions and song festivals increased, and they were organized in many localities by a semi-official federation. In 1864, 26 wind bands and choral societies founded an official federation (Allgemeiner Luxemburger Musikverein). The concert celebrating its official foundation was the occasion of the first performance, by 500 singers and musicians, of Zinnen’s anthem Ons Hémecht (“our homeland”), later to become the Grand Duchy’s national anthem. By 1914 the number of choral societies had grown to ca. 40. Many of these were based in the indistrial south with its developing steel industry. Here, choral societies and wind bands became meeting grounds for the sociable integration of Italian immigrants. [less ▲]

We assess the extent to which remotely-located firms are likely to discretionarily accumulate cash rather than distribute it to shareholders. We consider that these firms are less subject to shareholder scrutiny and, thus, will have high agency conflicts as the distance will facilitate the extraction of private benefits. Consistent with our predictions, we find a positive relation between the distance to the main metropolitan area and cash holdings, and this impact is more pronounced when the controlling shareholder has high levels of excess control rights (i.e., separation of cash-flow rights and control rights). Our results hold even after accounting for all control variables, including financial constraints, and suggest that geographic remoteness can be conducive to severe agency problems, particularly when there is a large separation of cash-flow rights and control rights.

In order to raise the question of a potential compatibility between the awareness of Otherness on the one hand, and a form of universality on the other, some hypotheses should first be formulated and defined. 1) How does moral relativism equate to the rejection of universal discourses? 2) Consequently, how can this rejection be understood as a result of Modernity? 3) How can Modernity be understood as recognition of Otherness? The current paper will attempt to outline some answers to these questions based on a comparative reading between Kelsen and Lefort. Firstly, in order to explicate the main lines of the Kelsenian relativistic axiology it seems crucial to consider his second edition of the Pure Theory of Law, since one can find within it the grounds for a limitation of human cognition. His Farewell Lecture, “What is justice?”, is also relevant to this theme since in it he claims that the human world is a world of relative and conflicting values. The combination of these two ideas leads to the rejection of Universalist discourses – identified with the ones of Natural Law theories – in the name of science. Secondly, three of Lefort’s articles seem to be relevant. The first, “The Image of the Body and Totalitarianism”, enables us to understand his symbolic political philosophy, and more importantly, to introduce his definition of Modernity. “Dissolution of Marks and Democratic Challenge” focuses more on the concept of moral relativism, whilst interpreting it as a consistent reaction to modern indeterminacy. Finally, “Politics and Human Rights” offers a restricted concept of Human Rights, reminiscent of Hannah Arendt’s views, namely that human rights mean the rights to have rights. [less ▲]

FULL TEXT Musical nationalism in Luxembourg does not follow the standard European pattern of a folk-inflected exceptionalism vis-à-vis the French/Italian/German mainstream, arising around the mid-19th century. Luxembourg was too small to initiate an own musical nationalism, and had been under foreign control for several centuries before developing into the direction of sovereignty between 1815 and 1890. At this time Luxembourg had only one music school, and no professional orchestra; but amateur ensembles began to emerge all over the country following the liberal constitution of 1848 which granted the right of association. Luxembourg composers born in the mid-century (e.g. Jean-Antoine Zinnen, 1827-1898, the composer of the national anthem) established themselves in the city of Luxembourg and composed for choir and for wind band; there is little overtly national bias in their work. In 1870 the diocese of Luxembourg was founded; this also had an influence on musical life. Henri Oberhoffer (1824-1885), organist at the cathedral of Luxembourg, and Laurent Menager (1835-1902) wrote sacred music; Oberhoffer was a champion of the Cecilian movement in Luxembourg with Franz Xaver Witt ran the periodical Cäcilia from 1862 to 1871. The outstanding composer of this first generation was Laurent Menager, the first to have studied music abroad – in Cologne, where he came in contact with several Romantic composers, among others his composition teacher Ferdinand Hiller. His 63 secular and sacred songs for four-part male choir and his 23 songs for voice and piano are a fine representation of the taste of the period, reminiscent of Schubert. [less ▲]

Industrial robots bear significant potential for increasing productivity of manufacturing operations. However, producing increasingly individualized products with an enhanced number of variants, the flexibility of the production system poses substantial challenges in order to robotize manual tasks. Comprehensive scientific research is required to provide tailored solutions for these manufacturing processes. This is true especially for small and medium sized companies (SME). The key note discusses the challenges of automating flexible manufacturing operations with examples from specific use cases with industrial background. We present automotive powertrain assembly, which requires agile robotic joining of rigid and complaint parts. However, as automation of many low volume processes is economically not advantageous, semi-automation and Human-Robot Collaboration are key enablers for robotizing small lot production. Human-Robot Collaboration requires novel technologies for dynamic workload distribution between worker and robot. Automating 3D surface grinding process is another example how scientific research contributes to increased manufacturing efficiency. [less ▲]

FULL TEXT The first folksong collection in Luxembourg, Die luxemburger Volkslieder älterer Zeit, compiled by the folklorist and ethnologist Edmond de la Fontaine (alias Dicks, 1823-1891), was published posthumously in 1904. It contains only forty songs, and due to the unscientific way they had been collected, some important information is missing; nonetheless it offers a first glipse into folksongs in 19th-century Luxembourg. Their lyrics were adapted to the Luxembourg context, although only a few songs originate from the country. A scholarly, methodical folksong collection following the model of Erk and Böhme’s Deutscher Liederhort (1893-94) was published in 1937, entitled Singendes Volk. Its author, Mattias Thill, a primary school teacher, spent about four decades collecting songs throughout the Grand Duchy; again, most songs are variants of existing songs of non-Luxembourgish origin, 65% from Germany and a mere 3% from France. The remaining 32% have Luxembourgish texts (which, again, speaks for their more complete integration into Luxembourg life, not necessarily for a Luxembourg origin). Indigenous songs are often related to the military history and to the fortress of Luxembourg. Folk music in Luxembourg is predominantly vocal, with the one curious exception of a mystical blind violin-playing minstrel, Matthias Schou (alias Blannen Theis, 1747-1824) who was led from parish fair to parish fair by his wife and entertained the peasant population with his songs. Until today no sources have been discovered, but it is assumed that this troubadour is at the origin of melodies gathered a century later. In three cases, songs were subsequently arranged to instrumental music at a later date and gained a persistent performative presence to the point of becoming markers of Luxembourgish musical identity: the Wilhelmus, the Song of the dancing Procession, and the Hämmelsmarsch The Wilhelmus is the anthem of the Grand-Ducal court (not of the country), and is performed at the occasion of an official appearance of the Grand-Duke or of a member of his family. The melody is a variant of the Dutch national anthem Wilhelmus van Nassouwe, evidently based on Mozart’s Seven variations on Wilem Van Nassau (1766, KV 25) The “Song of the Dancing Procession” originates from the famous Procession of Echternach, and is based on the German folksong Adam hatte sieben Söhn’, arranged to a Rheinländerpolka for wind band in a medium tempo suitable for pilgrims taking three steps forward and two steps backwards. The Hämmelsmarsch, a beggar song derived from a 14th-century shepherd’s fair song, was played by pipers and drummers while visitors had to pay a fee. Modern-day local wind bands maintain this tradition, strolling the streets during parish fairs and requesting financial donations while playing this song. [less ▲]

Die Veränderungen von 2014 zu 2015 fallen insgesamt moderater aus. Innerhalb dieses Zeitraums nimmt die Arbeitszufriedenheit der 16-24 Jährigen jedoch relativ stark ab. Arbeitnehmer mit portugiesischer Nationalität steigen in ihrer Arbeitszufriedenheit dagegen wieder an. Zu keinem der drei Erhebungszeitpunkte sind hinsichtlich der Arbeitszufriedenheit Unterschiede zwischen Männern und Frauen sowie zwischen Arbeitnehmern in Vollzeit und in Teilzeit festzustellen. Insgesamt berichten Manager und Führungskräfte sowie Arbeitnehmer in akademischen Berufen im Jahr 2015 über die höchste Arbeitszufriedenheit, dagegen Arbeitnehmer, die Anlagen und Maschinen bedienen sowie Arbeitnehmer, die in Land- und Forstwirtschaft beschäftigt sind, über die geringste Arbeitszufriedenheit.

This research establishes that religiosity has a persistent effect on economic outcomes. First we use a sample of migrants in the US to establish that religiosity at the country of origin has a long lasting effect on the religiosity of migrants. Second, exploiting variations in the inherited component of religiosity of migrants, our analysis uncovers the causal effect of religiosity on economic activity using a panel of countries for the period 1935-2000. The empirical findings suggest that i) church attendance has a positive impact on economic outcomes; ii) religious beliefs in the existence of god, hell, heaven and miracles have no systematic effect on economic outcomes, and iii) stronger faith is associated with prosperity. Moreover we extend our analysis to uncover the channels via which religiosity operates. Notably, the positive effect of religious participation and of stronger faith on economic outcomes operates via the creation of social capital and the development of traits, such as hard work and thrift, that are conducive to growth.

We explore time-memory and other tradeoffs for memory-hard functions, which are supposed to impose significant computational and time penalties if less memory is used than intended. We analyze two schemes: Catena, which has been presented at Asiacrypt 2014, and Lyra2, the fastest finalist of the Password Hashing Competition (PHC). We demonstrate that Catena's proof of tradeoff resilience is flawed, and attack it with a novel \emph{precomputation tradeoff}. We show that using $M^{2/3}$ memory instead of $M$ we may have no time penalties. We further generalize our method for a wide class of schemes with predictable memory access. For Lyra2, which addresses memory unpredictability (depending on the input), we develop a novel \emph{ranking tradeoff} and show how to decrease the time-memory and the time-area product by significant factors. We also generalize the ranking method for a wide class of schemes with unpredictable memory access [less ▲]
