John of Luxembourg became widely known as a legend, which authors of chronicles started to depict immediately after his death at Crécy. Until the 19th century, he was traditionally described as a valiant and loyal knight. However, research done in the last fifteen years changed this picture and shed a different light on it. John was undoubtedly an experienced warrior, but waging war was not his only activity. Latest research emphasizes especially his diplomatic skills. In the course of thirty‑six years he in fact attempted thirty‑six projects of marriage convenient for the Luxembourg dynasty. His policy within the Empire was dominated by his dream to acquire the imperial crown. The article focuses mainly on Johnʼs policies in the county of Luxembourg, where it was important to ensure tenancy of property and if possible, to expand its territory. It expanded successfully towards several of its neighbours, while in the case of Trier, it was only possible to defend the status quo. During his reign, he was one of the first counts in the Empire to use modern means of governance: collecting pecuniary dues from the serfs or appointing ministerial clerks responsible for administrative tasks, giving preference, especially in financial administration, to competent burghers. He had the land urbarium updated and was the first to appoint a general tax collector for the whole county. Under the rule of his son Charles, the focal point of the dynasty shifted to central Europe and the county of Luxembourg became, to its own detriment, a less important land frequently used as a pledge.

In the heated times of the Cold War, two hypothetical schoolboys – Johnny in the United States and Ivan in the Soviet Union (USSR) – were both promised a school where they would learn in a new way. This new way – the technology of programmed instruction – was developed by the American behavioral psychologist Burrhus F. Skinner. It became popular globally over the 1960s and was promoted passionately in the United States and the USSR alike. The aim of this article is to explore this shared sentiment, with the specific intention of explaining how, during the Cold War, an American innovation was able to become a hit in Soviet education under reform. Un­ derstanding educational transfer as translation rather than transportation, the article unveils the ways in which the idea of programmed learning became embedded and reconceptualized through the specific Soviet political, historical, and cultural lens of the time. The case of programmed instruction not only demonstrates that ideas become global only through their local reinvention but also illustrates that assumed scientific­ hence ­universal educational innovations or programs are never such.

This paper considers the joint design of bit loading, precoding and receive filters for a multiple-input multiple-output (MIMO) digital communication system employing decision feedback (DF) detection at the receiver. Both the transmitter as well as the receiver are assumed to know the channel matrix perfectly. It is well known that, for linear MIMO transceivers, a diagonal transmission (i.e., orthogonalization of the channel matrix) is optimal for some criteria. Surprisingly, it was shown five years ago that for the family of Schur-convex functions an additional rotation of the symbols is necessary. However, if the bit loading is optimized jointly with the linear transceiver, then this rotation is unnecessary. Similarly, for DF MIMO optimized transceivers a rotation of the symbols is sometimes needed. The main result of this paper shows that for a DF MIMO transceiver where the bit loading is jointly optimized with the transceiver filters, the rotation of the symbols becomes unnecessary, and because of this, also the DF part of the receiver is not required. The proof is based on a relaxation of the available bit rates on the individual substreams to the set of positive real numbers. In practice, the signal constellations are discrete and the optimal relaxed bit loading has to be rounded. It is shown that the loss due to rounding is small, and an upper bound on the maximum loss is derived. Numerical results are presented that confirm the theoretical results and demonstrate that orthogonal transmission and the truly optimal DF design perform almost equally well. [less ▲]

Herein, we study the spectral coexistence of Geostationary (GEO) Fixed Satellite Services (FSS) downlink and Broadcasting Satellite Services (BSS) feeder links in the Ka-band (17.3 − 18.1 GHz) which is primarily allocated for BSS feeder links. Firstly, a novel cognitive spectrum exploitation framework is proposed in order to utilize the available band efficiently. Subsequently, based on the interference analysis carried out between these systems, two cognitive approaches, namely Carrier Allocation (CA) and Beamforming (BF), are investigated under the considered framework assuming the availability of an accurate Radio Environment Map (REM). The employed techniques allow the flexibility of using additional shared carriers for the FSS downlink system along with the already available exclusive carriers (19.7 − 20.2 GHz), thus increasing the overall system throughput. It is shown that a significant improvement in the per beam throughput as well as in the beam availability can be achieved by applying CA and BF approaches in the considered scenario. [less ▲]

The potential gains of multiple antennas in wireless systems can be limited by the channel state information imperfections. In this context, this paper tackles the feedback in multiuser correlated multiple input single output (MU-MISO). We propose a framework to feedback the minimum number of bits without performance degradation. This framework is based on decorrelating the channel state information by compression and then quantize the compressed (CSI) and feedback it to the base station (BS). We characterize the rate loss resulted from the proposed framework. An upper bound on the rate loss is derived in terms of the amount of feedback and the statistics of the channel. Based on this characterization, we propose am adaptive bit allocation algorithm that takes into the account the channel statistics to reduce the rate loss induced by the quantization. Moreover, in order to maintain a constant rate loss with respect to the perfect CSIT case, it is shown that the number of feedback bits should scale linearly with the SNR (in dB) and to the rank of the user transmit correlation matrix. We validate the proposed framework by Monte-carlo simulations. [less ▲]
