Throughout her academic projects, Dr Ganschow is working on the presence of the so-called Russian diaspora in Luxembourg, i.e. the emigrant population from former Soviet Republics. Her current project deals with Soviet forced labourers during the Second World War and is commissioned by the Luxembourg government. In her work, she decided to compare the situation of these forced labourers, mainly young women coming from Ukraine, with the local population, in the Belval region in the south of Luxembourg. Another interview topic is LURN network (Luxembourg Ukrainian Researcher Network) which aims to connect Ukrainian researchers displaced by the war and who are temporarily working in Luxembourg for research institutions. It also aims to provide additional points of contact with the Luxembourg research community. The LURN already organised three different meetings and workshops since its creation in August 2022, facilitating Ukrainian scholars contacts in Luxembourg new environment, and stimulating new research projects.

In this interview, Professor Andrew Prescott describes his beginnings as a librarian and how this profession brought him to the field of digital humanities. He emphasizes more broadly the role of curators in this field including the role of metadata and the configuration of collections in a new way. Andrew Prescott also historicizes the digital turn in humanities and explores the most exciting trends for the future. [less ▲]

In this interview, Professor Jane Winters gives an overview of her career, starting as a medieval historian to becoming a professor in digital history. She talks about her main work with born digital archives and reflects on how web archive changes historical research. ‘History from below’ with a big interest in genealogy and local history being very popular in the UK, she describes the character of digital history in her country and the response of both amateur and professional historians to digitisation. She pleads for more digital pedagogy at an earlier stage of the curriculum and underlines the importance of the relationship between digital humanities and other stakeholders like librarians and archivists. In her view, the next big challenge in digital humanities will be the non-text media analysis. [less ▲]

In this interview, Professor Tim Hitchcock describes his beginnings as an historian in British social history and how he became involved in the field of digital humanities. He explains how he started with Robert Shoemaker in the late 1990’s big digitization projects like “Old Bailey online” (The Proceedings of the Old Bailey, 1674-1913). He emphasizes also the role of digital history in connection with the history from below in the United Kingdom and public history in the United States. Tim Hitchcock also criticizes the way in which a lot of historians meet the digital challenge and underlines the importance of the use of digital tools in the undergraduates curriculum in the University of Sussex. He also explains the interactions between close reading and distant reading, how historians nowadays deal with it, and describes the perspectives for digital history in the future. [less ▲]

Interweave/Underlay Cognitive Radio Techniques and Applications in Satellite Communication Systems

The demand for precious radio spectrum is continuously increasing while the available radio frequency resource has become scarce due to spectrum segmentation and the dedicated frequency allocation of standardized wireless systems. This scarcity has led to the concept of cognitive radio communication which comprises a variety of techniques capable of allowing the coexistence of licensed and unlicensed systems over the same spectrum. In this context, this thesis focuses on interweave and underlay cognitive radio paradigms which are widely considered as important enablers for realizing cognitive radio technology. In the interweave paradigm, an unlicensed user explores the spectral holes by means of some spectrum awareness methods and utilizes the available spectral availabilities opportunistically while in the underlay paradigm, an unlicensed user is allowed to coexist with the licensed user only if sufficient protection to the licensed user can be guaranteed. Starting with a detailed overview of the existing techniques, this thesis provides contributions in both theoretical and the practical aspects of these paradigms. This thesis is structured into two main parts as described below. One of the important capabilities required for a cognitive radio transceiver is to be able to acquire the knowledge of its surrounding radio environment in order to utilize the available spectral opportunities efficiently. The higher the level of information it can acquire, the better becomes the spectrum utilization. In this context, the first part of this thesis focuses on spectrum awareness techniques such as spectrum sensing, signal to noise ratio estimation and sparsity order estimation which are useful for realizing interweave and underlay based cognitive transceivers as well as a hybrid cognitive transceiver, which overcomes the drawbacks of both the above approaches. The effects of noise and channel correlations, which are often neglected in the existing literature, are considered in our analysis. In the above context, firstly, we propose new sensing thresholds for the eigenvalue based sensing approach using recent results from random matrix theory in order to achieve the improved sensing in correlated scenarios. Then we study the signal to noise ratio estimation problem for both narrowband and wideband transceivers with the help of a detailed theoretical analysis under the signal plus noise hypothesis for a range of correlated scenarios. Subsequently, we study the problem of compressive sparsity order estimation in order to estimate the sparsity order of the carrier occupancy over the wide spectrum using a compressive sensing approach. In addition, we carry out the performance analysis of a hybrid cognitive transceiver which combines the spectrum sensing approach with a power control-based underlay approach. The second part of this thesis introduces the concept of cognitive satellite communications which is a rather unexplored area in the literature despite its significant benefits to both satellite and terrestrial operators. This concept has been motivated due to the limited availability of the satellite spectrum as well as the continuously increasing demand of broadband multimedia, broadcast and interactive satellite services. Subsequently, we study the applications of various cognitive radio techniques in satellite communication systems focusing on the following two scenarios: (i) Hybrid cognitive satellite communication which deals with the spectral coexistence of satellite systems with the terrestrial systems, and (ii) Dual cognitive satellite communication which deals with the spectral coexistence of two satellite systems operating over the same coverage area. Understanding the characteristics of coexisting systems is of great importance while applying a suitable cognitive radio technique. In this context, this thesis exploits the specific characteristics of satellite systems in order to map a suitable cognitive radio technique to a specific scenario. For hybrid cognitive scenarios, we propose the following enabling techniques: (a) Interference modeling, (b) Harmful interference detection, (c) Cognitive beamforming including both transmit and receive beamforming, and (d) Dual-polarized spectrum sensing. Similarly, for dual cognitive scenarios, we propose the following techniques: (i) Cognitive interference alignment, (ii) Cognitive beamhopping, and (iii) Dual-polarized spectrum sensing. Finally, we provide interesting open research issues in the considered domain. [less ▲]
