Alexandre Serres’ PhD, “Aux sources d’Internet: l’!emergence d’ARPANET” (“The origins of the Internet: the Emergence of ARPANET”), defended in 2000, is quite influential in Francophone research literature and discourse on Internet histories. However, yet untranslated, it has remained little known in Anglophone scholarly circles. The results of this thesis, which strongly echoes other articles and interviews, that are part of this special issue on ARPANET, remain still relevant and valid and we have chosen to introduce the reader to the final part of Serres’ research – an inevitable choice within the 600 pages of this work.

This chapter focuses on implicit attitudes toward smoking and provides the first systematic review of research in this domain. Implicit attitudes are suggested to guide automatic behavior, thereby playing a pivotal role for automatic processes inherent in addictive behaviors. This chapter further explores the extent to which implicit attitudes are context-sensitive. More specifically, it reviews studies that have focused on the differential effects of external cues such as warning labels and internal cues (e.g., deprivation). Results of 32 studies show that although smokers generally have more positive implicit attitudes than non-smokers, the valence of implicit attitudes varies as a result of the applied method or stimuli. Studies reveal that implicit attitudes toward smoking partly depend on external cues, especially outcome expectancies. Similarly, internal cues affect implicit attitudes whereby the level of nicotine deprivation seems vital. Implications for intervention and future research are indicated in the discussion. [less ▲]

The MQTT application protocol was originally designed for monitoring a oil pipeline through the desert by collecting sensor data via satellite link. Thus, by design MQTT is very suitable for data collection over integrated satellite-terrestrial networks. Leveraging on the MQTT Bridge functionality, in this work we propose a novel architecture with two MQTT Brokers located at the satellite terminal and the satellite gateway. By using the topic pattern option, supported by the bridge, a subscriber can request several topics within a single request. To reduce the amount of traffic ex-changed over the satellite return channel, we introduce in the architecture a new entity, namely MQTT message aggregation filter, which aggregates all the MQTT topics matching the topic pattern in the same response.

The Laser Technology Competence Centre (LTCC) of the University of Luxembourg provides skills in joining material combinations, which are considered being non-weld able with traditional methods or at least challenging to join (e.g. Copper and Aluminium, Aluminium and Polyamide (PA), Titanium and PEEK, steel and tungsten hard alloy). Related accomplishments include minimal intermetallic compounds, convincing mechanical and superior electrical properties of the laser-welded specimen. With defined spatial and temporal modulation of the laser beam, an accurately defined temperature profile is created on the lower side of the upper material in the two dimensional directions, which enable joining of dissimilar materials in overlap configurations, despite challenging thermal properties. To weld butt-joint geometries with minimal heat affected volume, the temperature profiles were expanded in the third dimension, which can be achieved through controlled laser energy guidance. The scientific methods to accomplish these convincing results are explained, with selected industrial use cases ranging from automotive industry, energy storage, and medical implants. An outlook with unsolved challenges is intended to ignite discussions about upcoming research topics. [less ▲]

In September 2018, the European Commission presented a draft Regulation on preventing the dissemination of terrorist content online. The proposal builds upon EU-level initiatives to foster the voluntary cooperation of service providers in stopping the dissemination of terrorist content online, and echoes ongoing national developments which go a step further in imposing obligations – underpinned by considerable fines – on service providers. This article describes the main features of the proposal and highlights some of the policy challenges, legal questions and technological concerns it is likely to face on the road to adoption.

We demonstrate the potential for the Global Positioning System (GPS) to provide highly accurate tropospheric products for use in meteorological applications. Tropospheric products, in particular the wet delays, are treated as an unknown parameter in GPS processing and are estimated with other parameters such as station coordinates. In this study, we investigate the effects of Phase Center Correction (PCC) models on tropospheric zenith wet delay (ZWD), integrated water vapor (IWV) and gradient products. Two solutions were generated using the GAMIT software over the EUREF Permanent GNSS Network (EPN). The first (reference) solution was derived by applying the International GNSS Service (IGS) type-mean PCC model, while for the second solution PCC models from individual calibrations were used. The solutions were generated identically, except for the PCC model differences. The two solutions were compared, with the assumption that common signals are differenced out. The comparison of the two solutions clearly shows a bias in all tropospheric products, which can be attributed to PCC model deficiencies. Overall, mean biases of ±1.8, ±0.3, ±0.14 and ±0.19 mm are evident in ZWD, IWV, North-South and East-West gradients, respectively. Moreover, the differences between the two solutions show seasonal variations. For all antenna types, the ZWD and IWV differences are dominated by white plus power-law noise, with latter characterizing the low-frequency spectrum. On the other hand, the horizontal gradients exhibit a white plus first order autoregressive noise characteristic with less than 1% white noise. The individual PCC model provides a better fit to an external independent model in terms of gradient estimate and also provides up to 3 % more carrier phase ambiguity resolution. [less ▲]

Energy consumption is one of the main limiting factors for the design of ultrascale infrastructures. Multi-level hardware and software optimizations must be designed and explored in order to reduce energy consumption for these largescale equipment. This chapter addresses the issue of energy efficiency of ultrascale systems in front of other quality metrics. The goal of this chapter is to explore the design of metrics, analysis, frameworks and tools for putting energy awareness and energy efficiency at the next stage. Significant emphasis will be placed on the idea of “energy complexity,” reflecting the synergies between energy efficiency and quality of service, resilience and performance, by studying computation power, communication/data sharing power, data access power, algorithm energy consumption, etc. [less ▲]
