abstract = {{ In the debate on the integration of information and communication technologies (ICT) into schools, the beliefs and attitudes of teachers towards ICT in teaching and learning have always been regarded as central criteria for successful implementation of new technologies. In this context, a study in 2013 by the International Association for the Evaluation of Educational Achievement, IEA, provided insights into teachers’ beliefs regarding ICT and showed that perceptions of the pedagogical advantages of technologies differ between countries. With regard to this finding, this paper seeks to determine whether there is a typology of teachers with different attitudes towards the potential of ICTs for learning. This question is addressed by conducting latent class analyses on a sample of teacher data from three European countries – the Czech Republic, Germany and Norway. Furthermore, the paper investigates how the use of computers by teachers varies between the groups to which these teachers can be assigned. In doing so the research reported at hand connects, arguably for the first time, representative data on teacher typologies of attitudes towards and beliefs about ICT in teaching and learning with data on computer use in schools. }},

abstract = {{ The International Computer and Information Literacy Study (ICILS 2013) provides, for the first time, information about students’ computer and information literacy (CIL), as well as its acquisition, based on a computer-based test for students and background questionnaires. Among the 21 education systems that participated in ICILS 2013, there are 12 European countries, making secondary comparative in-depth analyses at a European level particularly fruitful. Accordingly, while the four articles in this Special Issue each deal with different topics and adopt different methodologies, they all share a common element and provide European comparisons in the ICILS context. The editorial in turn outlines the aim of the ICILS 2013 study and its relevance for European education research as well as its contextual framework and approach to the measurement of students’ CIL. The potential and challenges of such large-scale assessment studies are also discussed. }},

abstract = {{Wireless Sensor Networks (WSN) consist of large number of distributed sensors nodes which are able to sense,
read and transmit physical measurements such as temperature, humidity and pressure over wireless
communication links. WSN nodes are often powered by batteries or can use energy harvesting methods from
environmental energy sources. One of the major challenges in the design of WSN nodes is the high level of
power dissipation for sensing, processing and communication. Operating at low-power levels reduces
maintenance effort for periodic battery replacement or can even provide unlimited operation by means of energy
harvesting. Since the communication process is the most power hungry process, ultra-low-power wireless
communication is an enabler for network applications such as cyber-physical systems, Internet-of-Things and
Industry 4.0 etc. Our research is based on Wake-up Receivers (WuR) architectures. Each of the WSN nodes contains a WuR
which is always-on, listening for a wake-up signal from other nodes or the base station, and activating the node
only when a wake-up signal is detected. By this scheme the communication with the base station becomes
asynchronous, real-time and on-demand. Due to the centrally-coordinated, collision-free communication such
WSNs can be scaled to very large node numbers. Designing always-on WuR at ultra-low-power dissipation
levels makes the WSN nodes very energy efficient because they are only activated when a wake-up-signal is
received. Additionally, the WuR must be robust to noise and co-channel interference in order to operate safely
in parallel to other wireless systems. We investigate a novel radio architecture for the WuR using Linear Frequency Modulation (LFM) and passive
analog signal processing by means of a Surface Acoustic Wave (SAW) correlator. The base station sends the
required WSN node ID using LFM signal at 2.4 GHz. The node ID is encoded as chirp up or chirp down signal
with chirping bandwidth of 80MHz. On the receiver side, the SAW chirp correlator demodulates the received
LFM signal while suppressing other wireless signals. In order to achieve proper demodulation and high Signal-to-Noise Ratio (SNR), the SAW correlator is designed to behave like a Matched Filter (MF) which boosts up the
SNR. After that the signal is amplified/detected by baseband amplifier stage, it is compared with the unique ID
of the node, and the node's Wake up signal is asserted accordingly. Since the SAW correlator operates
completely passive, the WuR can be implemented in a very energy-efficient way, without the need to use power
hungry device such as Low Noise Amplifiers (LNA) or down conversion Local Oscillators (LO)}},

Mixed signal baseband realization allows for easier implementation of the channel equalization function and eliminates the need for high speed data converters. System design and architecture of a mixed signal baseband processor for 100 Gbps wireless communication is described that reduces the implementation complexity and results in a consequent reduction in power dissipation and chip area. An ultra-broadband analog correlator consisting of a four-quadrant multiplier and a fast resettable integrator using only NPN transistors was designed, fabricated, and measured. The correlator circuit is the core component of the receiver baseband. To the best knowledge of the authors, it is the fastest correlator circuit published so far.}},
