Abstract (sommario):

AbstractIn this paper, a high-gain dual-band distributed amplifier (DBDA) based on the metamaterial transmission line (TL) is proposed. To have two separate frequency bands in the distributed amplifiers, the composite right/left-handed (CRLH) TLs are used instead of conventional TLs. Although both forward and reverse gains of the distributed amplifiers are available in this case, they suffer from their low gains. In this paper, to increase the DBDA power gain, a new circuit architecture for the CRLH TL is introduced. By using the proposed CRLH TL, a lower wave attenuation coefficient at the forward band of the DBDA is achieved than the conventional structures, which causes a higher forward power gain. Simulation results also show that the power gain of the proposed DBDA is about 28.5 dB at the desired frequency bands, and good agreement between the measurement and simulation results confirms the accuracy of the design method.

Abstract (sommario):

This article argues for an unorthodox reading of Israel's current political situation. Rather than examine the immediate results of the March 2015 elections, it lays out the ramifications of the country's current predicament in light of the complex relations between the Jewish majority and Palestinian Arab minority. The author contends that despite the seeming stranglehold that extremist nationalism exerts on the political process, there is true potential for Palestinian citizens of Israel (PCI) to gain full and equal citizenship, on a par with that of their Jewish counterparts. He argues further that the PCI may be poised to lead the Palestinian national movement in advancing a political resolution to the conflict with Israel.

Abstract (sommario):

As the demand for more efficient alternative energies increases, the demand to make the power electronics that go along with those energies increases as well. One of the major power components for photovoltaics is the DC-DC converter required to increase the voltage produced. A hybrid DC-DC boost-forward topology was explored. A switch on the secondary side can be turned off and the converter will take the characteristics of a boost converter. These predictions were confirmed by simulating this cirucit in MatLab Simulink, and finally by building a prototype circuit. A desired output of 170V - 100W was produced and the efficiency was measured. The boost-forward converter peaked at about 85% efficient which was below the 94% efficient boost converter. The boost-forward converter, however, was found to have a higher efficiency than the boost converter when the input voltage was below 34V . The circuit is designed to work as a boost converter when the input voltage is above 34V . When the input drops below that voltage the converter can be put into the boost-forward converter configuration by closing the switch on the secondary side.

Abstract (sommario):

Dans les systèmes radio mobiles, la diversité représente une technique efficace pour lutter contre l’évanouissement dû aux multi-trajets. La pleine diversité spatiale est atteinte dans les systèmes multiple-input multiple-output (MIMO). Mais, souvent l’intégration d’antennes multiples au niveau de l’émetteur ou du récepteur est coûteuse. Comme alternative, dans les réseaux sans fil multi-hop, la diversité coopérative garantit des gains de diversité spatiale en exploitant les techniques MIMO traditionnelles sans avoir besoin d’antennes multiples. En outre, la diversité coopérative fournit au réseau : un débit important, une énergie réduite et une couverture d’accès améliorée.Dans ce contexte, l’objectif de cette thèse est de concevoir des schémas de codage pour le canal à relais afin de réaliser une meilleure performance en termes de gain de diversité et de gain de codage. D’abord, nous étudions un système de turbo-codage distribué à L-relais en mode soft-decode-and-forward. Ensuite, nous proposons un système de turbocodage coopératif distribué à L-relais en utilisant la concaténation en parallèle des codes convolutifs. Enfin, afin d’améliorer la fiabilité de détection au niveau du noeud relais, nous proposons la technique de sélection d’antenne/relayage-soft. Pour une modulation BPSK, nous dérivons des expressions de la borne supérieure de la probabilité d’erreurbinaire où les différents sous-canaux sont supposés à évanouissement de Rayleigh, indépendants et pleinement entrelacés avec une information instantanée d’état de canal idéal. Une validation des résultats théoriques est également menée par la simulation
Diversity provides an efficient method for combating multipath fading in mobile radio systems. One of the most common forms of spatial diversity is multiple-input multipleoutput (MIMO), where full diversity is obtained. However, embedding multiple antennas at the transmitter or the receiver can sometimes be expensive. As an alternative to collocated antennas, cooperative diversity in wireless multi-hop networks confirms their ability to achieve spatial diversity gains by exploiting the spatial diversity of the traditional MIMO techniques, without each node necessarily having multiple antennas. In addition, cooperative diversity has been shown to provide the network with importantthroughput, reduced energy requirements and improved access coverage.In light of this, the objective of this thesis is to devise coding schemes suitable for relay channels that aim at showing the best compromise between performance of diversity and coding gains. Firstly, we investigate a distributed turbo coding scheme dedicated to L-relay channels operating in the soft-decode-and-forward mode. Then, we present a proposed distributed turbo coded cooperative (DTCC) scheme, called parallel concatenated convolutional-based distributed coded cooperation. Finally, we investigate antenna/soft-relaying selection for DTCC networks in order to improve their end-to-end performance. Assuming BPSK transmission for fully interleaved channels with ideal channel state information, we define the explicit upper bounds for error probability inRayleigh fading channels with independent fading. Both theoretical limits and simulation results are presented to demonstrate the performances

Abstract (sommario):

The superior characteristics of silicon carbide, compared with silicon, have suggested considering this material for the next generation of power semiconductor devices. Among the different power switches, the bipolar junction transistor (BJT) can provide a very low forward voltage drop, a high current capability and a fast switching speed. However, in order to compete on the market, it is crucial to a have high current gain and a breakdown voltage close to ideal. Moreover, the absence of conductivity modulation and long-term stability has to be solved. In this thesis, these topics are investigated comparing simulations and measurements. Initially, an efficient etched JTE has been simulated and fabricated. In agreement with the simulations, the fabricated diodes exhibit the highest BV of around 4.3 kV when a two-zone JTE is implemented. Furthermore, the simulations and measurements demonstrate a good agreement between the electric field distribution inside the device and the optical luminescence measured at breakdown. Additionally, an accurate model to simulate the forward characteristics of 4H-SiC BJTs is presented. In order to validate the model, the simulated current gains are compared with measurements at different temperatures and different base-emitter geometries. Moreover, the simulations and measurements of the on-resistance are compared at different base currents and different temperatures. This comparison, coupled with a detailed analysis of the carrier concentration inside the BJT, indicates that internal forward biasing of the base-collector junction limits the BJT to operate at high current density and low forward voltage drop simultaneously. In agreement with the measurements, a design with a highly-doped extrinsic base is proposed to alleviate this problem. In addition to the static characteristics, the comparison of measured and simulated switching waveforms demonstrates that the SiC BJT can provide fast switching speed when it acts as a unipolar device. This is crucial to have low power losses during transient. Finally, the long-term stability is investigated. It is observed that the electrical stress of the base-emitter diode produces current gain degradation; however, the degradation mechanisms are still unclear. In fact, the analysis of the measured Gummel plot suggests that the reduction of the carrier lifetime in the base-emitter region might be only one of the causes of this degradation. In addition, the current gain degradation due to ionizing radiation is investigated comparing the simulations and measurements. The simulations suggest that the creation of positive charge in the passivation layer can increase the base current; this increase is also observed in the electrical measurements.

Abstract (sommario):

Nous étudions un protocole de coopération dans les réseaux MIMO à deux sauts : le rotate-and-forward (RF). Dans ces réseaux, la source et la destination ne communiquent qu'à travers une couche de relais. Nous étudions la performance du protocole RF à partir d'une nouvelle métrique appelée gain de coupure. Ce gain nous permet de décrire le comportement de la probabilité de coupure à des valeurs du rapport signal à bruit moyennes et élevées. En utilisant le gain de coupure, nous comparons la performance du RF aux performances d'autres protocoles ayant le même ordre de diversité que le RF. Nous supposons aussi qu'une voie de retour existe entre la destination et les relais et nous donnons un algorithme qui permet d'améliorer les performances du RF en termes de probabilité de coupure en se basant sur la connaissance des gains du canal. Nous considérons un protocole de codage de réseaux au niveau physique : le compute-and-forward (CF). Nous nous intéressons à la maximisation du débit de calcul et nous montrons que c'est équivalent à la recherche du vecteur le plus court dans un réseau de points donné. Tout d'abord, nous implémentons le protocole utilisant des réseaux de points uni-dimensionnels et des gains de canal réels. Nous nous basons sur la fonction de maximum de vraisemblance (ML) pour proposer une technique de décodage quasi-ML et nous montrons que le décodage s'effectue par une approximation Diophantienne inhomogène. Ensuite, nous généralisons certains de ces résultats au cas des réseaux de points multi-dimensionnels et des gains de canal complexes, et nous proposons un critère de construction des codes en réseaux de points qu'on appelle le facteur de platitude.

Abstract (sommario):

Dans un réseau coopératif, différents noeuds coopèrent afin de créer un réseau d’antennes virtuel et exploiter la diversité spatio-temporelle. On s’intéresse d'abord au canal à relai. Afin d'améliorer les performances à bas SNR, on propose une stratégie adaptative pour les protocoles ”amplify-and-forward” (AF) et ”decode-and-forward (DF) qui détermine la meilleure technique de transmission en fonction du canal. Afin de définir un protocole DF à la fois performant et facile à implémenter, on propose ensuite d'utiliser un décodage incomplet aux relais. Cette technique permet d’atteindre les gains de multiplexage et de diversité maximaux, son DMT est le même que celui du protocol AF non-orthogonal (NAF). Pour réduire la complexité aux relais, deux nouvelles méthodes de décodage sont proposées, basées pour l’une sur la structure des codes TAST, et pour l’autre sur une approximation diophantienne. Dans le cas où plusieurs sources transmettent simultanément, on parle de canal coopératif à accès multiple (CMA). Une implémentation pratique et deux améliorations du protocole CMA-NAF sont proposées, ainsi qu’une variante utilisant une stratégie DF. Ces protocoles permettent d’atteindre de meilleures performances asymptotiques et leur DMT est plus proche de la borne MISO. Enfin, si le lien direct entre source et destination est inutilisable, on utilise une stratégie multi-saut. Dans cette thèse, on propose un protocole pour le canal ”K-parallel-path” (KPP), basé sur la sélection de chemin combinée avec un code spatio-temporel de faible dimension. Ce protocole permet d’atteindre les limites théoriques du canal tout en ayant une complexité limitée
In cooperative networks, multiple nodes cooperate to form a virtual antenna array and exploit space-time diversity. The relay channel is first investigated. In order to improve performance at low SNRs, an adaptive strategy is proposed for both amplify-and-forward (AF) and decode-and-forward (DF) protocols. This strategy chooses the best transmission scheme in term of mutual information for each channel realization. To define an easily implementable and efficient DF protocol, we propose to use an incomplete decoding at relays. This technique provides both full rate and full diversity. Its DMT is similar to the one of the well-known non-orthogonal AF (NAF). In order to reduce the decoding complexity at relays, we also propose two decoding methods based on the space-time block code (STBC) structure and diophantine approximation, respectively. When several sources need to transmit simultaneously, a cooperative multiple access (CMA) channel has to be considered. A practical implementation and two modifications of the CMA-NAF protocol defined by Azarian et al. Are proposed, as well as a DF variant, the CMA-IDF. These protocols provide better asymptotic performance and their DMT is closer to the MISO bound. Finally, if the direct link between source and destination is nonexistent or experiences too much fading, a multihop strategy has to be used. In this thesis, a protocol is proposed for the K-parallel-path (KPP) network, based on path selection combined with a small STBC. This protocol achieves the optimal DMT of the KPP channel with a limited complexity

This master’s thesis deals with the design of the switching power supply on the principle of high frequency converter. The goal of this thesis is construction of converter which is using GaN MOSFET transistors and SiC diodes for switching. The converter uses two switch forward power supply topology. Unusually high switching frequency was chosen for the design with power transformer with open magnetic core. The outcome of this work is functional converter which is primarily intended for educational and demonstrational purposes. Multiple parts of this converter are divided into individual blocks, which can be further used for construction of other types of switching converters.

This chapter offers an introduction to the book. Modality is a core research topic for most disciplines interested in language, including linguistics, philosophy, and psychology. By putting forward specific case studies across an extensive range of languages, the chapters in this book allow us to gain insights into features that are common across languages in the construction of modal meanings, as well as into constraints that are language-specific. The broad range of syntactic and morphological configurations under study in this book succeed in giving readers a sense of the extremely rich diversity found in natural language under the “modal umbrella.”

Abstract (sommario):

Commodity investments have continued to gain traction in diversified portfolios since the 1990s. Historically low correlations relative to traditional asset classes, different fundamental drivers, and investor demand for alternative sources of return have brought commodity investments forward as a solution that provides overall portfolio diversification while maintaining similar long-term return streams. A large inflow of institutional investors and noncommercial traders has increased demand and lowered barriers to entry. Many of these investors simply want exposure to commodities as an asset class, often investing in index funds or exchange-traded funds (ETFs). In some cases, investors assume that the underlying commodity indexes that these investment vehicles track represent appropriate benchmarks asset class performance. In reality, the many different commodity indexes available make benchmarking asset class performance more difficult.

Abstract (sommario):

Cyber conflict is often called the fifth domain of conflict. As more and more systems, networks, and information become digitized, there is contestation as to the growing nature of the threat and how exactly this domain can be exploited to coerce the enemy for either geopolitical or financial gain. Some argue that the cyber threat is exponentially growing and that offensive dominance reigns, making cyber conflict extremely unstable. Others contest that the threat is overblown and is more socially constructed. In this chapter we take a middle ground and find that much of the cyber conflict and security discourse has gotten it wrong through conjecture and worst- (or best-) case scenarios. We argue that a system of norms must be built upon and preserved to keep cyberspace a domain of relative openness and nonescalation. Arms races and deterrence strategies are not the path forward for a secure, prosperous cyberspace.

AbstractNowcasting macroeconomic aggregates have proved extremely useful for policy-makers or financial investors, in order to get real-time, reliable information to monitor a given economy or sector. Recently, we have witnessed the arrival of new large databases of alternative data, stemming from the Internet, social media, satellites, fixed sensors, or texts. By correctly accounting for those data, especially by using appropriate statistical and econometric approaches, the empirical literature has shown evidence of some gain in nowcasting ability. In this chapter, we propose to review recent advances of the literature on the topic, and we put forward innovative alternative indicators to monitor the Chinese and US economies.

Abstract (sommario):

ZusammenfassungWithin the field of capital market research, two diametrically opposed conceptions continue to be prevailing: The efficient market hypothesis by Fama (1970) on the one hand and the behavioral finance approach by Shiller (2003) on the other hand. According to Fama (1970), capital markets are efficient in a sense that current prices of securities incorporate all information available up to that point in time. Consequently, following Fama’s reasoning, there exist no possibilities to gain riskless profits by exploiting mispricings (so-called arbitrage) (Fama, 1970). Shiller (2003), in contrast, puts forward the claim that markets tend to behave irrationally, implying that there indeed exist possibilities to exploit mispricings.

Abstract (sommario):

AbstractThe very nature of what constitutes an effective learning environment is undergoing substantial re-imagination. Authors have suggested that the affordances of existing learning spaces, often termed conventional or traditional classrooms, is limited and constrains the possible pedagogies available to teachers. Architects, authors and governments have put forward innovative learning environments (ILEs) as a better alternative. ILEs provide affordances thought to be somewhat better at providing to students learning needs than traditional classrooms, particularly in terms of creative and critical thinking, and collaborative and communicative workers. However, there is little evidence available to show of either spatial type (traditional classroom or ILE) performs pedagogically to either hinder or support the desired approach/es to teaching and learning being sought by current educational policies. One could suggest that a populistic narrative often drives the growing investment in new school learning spaces, facilitated by a vacuum of credible evidence of their impact. This paper will report findings from a three-year study that tracked the practices over time of secondary school Engineering, Mathematics and Science teachers (n = 23) as they occupied two quite dissimilar spatial layouts. The Linking Pedagogy, Technology, and Space (LPTS) observational metric, with its provision of instantaneous quantitative visual analysis, was used to track their practice, and student learning, in a variety of spatial layouts. Subsequent analysis identified broad trends within the data to identify those factors, spatial, subject or confounding teacher factors, which influenced student and teacher activities and behaviours. Importantly, it presented new evidence that works against the current, overt focus on contemporary spatial design. It suggests that greater emphasis on unpacking, and then developing, the mediating influence of teacher spatial competency (how, when and why one uses the given affordances of space for pedagogical gain) is required for any space to performance pedagogically.

RESEARCH PRIORITIES: Western Balkans Snapshot. RESOLVE Network, ottobre 2020. http://dx.doi.org/10.37805/rp2020.1.wb.

Abstract (sommario):

Amidst the evolving threat of violent extremism (VE) worldwide, the Western Balkans face substantial challenges to social cohesion and stability. As elsewhere, narratives of religious, far right, and nationalist militancy resonate with vulnerable youth populations in Western Balkan countries where a history of ethnic, religious, and civil strife created a situation vulnerable to terrorist recruitment at home and abroad. Individuals who traveled to fight alongside violent extremist organizations abroad are returning to their home countries following the territorial losses of extremist groups in Syria and Iraq. At the same time, ethno-nationalist extremism continues to gain traction and expand across the region. While some of these topics have received increased attention in the current body of literature, others remain under-researched. Existing research topics also require more field research and deeper conceptual foundation. The resulting gaps in our collective understanding point to the need for further research on evolving social and VE dynamics in the Western Balkans. More rigorous and grounded research, in this regard, can help inform and improve efforts to prevent and counter violent extremism (P/CVE) in the region. In 2019, the RESOLVE Network convened local and international experts to discuss research gaps and develop a preliminary list of research priorities for P/CVE moving forward in the Western Balkans. The topics identified in this Research Priorities Snapshot reflect their collective expertise, in-depth understanding, and commitment to continued analysis of VE trends and dynamics in the region.
