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 ▲]

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 ▲]

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 ▲]

The Greater Region Saar-Lor-Lux is a geographic space constituted by two German border regions (Saarland and Rhineland-Palatinate), one French (Lorraine), one Belgian border region (Wallonia) and a small country (Luxembourg). In this area situated in the centre of the European Union, new dynamics of employment are observed especially with the development of cross-border labour: more and more people live and work in two different countries. Cross-border labour and its different forms have positive and negative effects on the composition of regional labour markets and more generally on the economic and social development of these different border regions.

Die Arbeitszufriedenheit der Arbeitnehmer in Luxemburg hat sich von 2013 zu 2014 insgesamt verringert. Von diesem Rückgang waren insbesondere Arbeitnehmer in der Altersklasse der 45-54 Jährigen, Arbeitnehmer mit portugiesischer Nationalität sowie in Belgien wohnhafte Arbeitnehmer betroffen. 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.

The relevance of Human Robot Interaction to complement human skills in a manufacturing environment with industrial robots increases the concerns over safety of human and the robot. It is necessary to identify collision risks and avoid them otherwise production stops may cost a huge amount to the industry. A robot working at manufacturing facility should be able to predict potential collisions and must be able to prevent i.e. react automatically for safe detour around obstacle/human. Currently, industrial robots are able to detect collisions after a real contact but the existing proposals for avoiding collisions are either computationally expensive or not very well adapted to human safety. The objective of this paper is to provide intelligence to the industrial robot to predict collision risks and react automatically without stopping the production in a static environment. The proposed approach using Time of Flight (TOF) camera, provides decision regarding trajectory correction and improvement by shifting robot to a secure position. The application presented in this paper is for safe KUKA robot trajectory generation in peg-in-hole assembly process in the laboratory context. [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 ▲]
