Antennas are one of the key components that empower a new generation of wireless technologies, such as 5G and new radar systems. It has been shown that antenna design strategies based on modal theories represent a powerful systematic approach to design practical antenna systems with high performance. In this thesis, several innovative multi-antenna systems are proposed for wireless applications in
This paper deals with propagation and channel modeling for physically large arrays. The focus lies on acquiring a spatially consistent model, which is essential, especially for positioning and sensing applications. Ultra-wideband, synthetic array measurement data have been acquired with large positioning devices to support this research. We present a modified multipath channel model that accounts
Psalm studies at the end of the twentieth century bear witness of a major paradigm shift. Recent research no longer treats the Book of Psalms as a loosely assembled hymnbook with no overarching organization, but rather as a book that got its present shape through careful editing. In recent years an increasing interest in the arrangement of the Book of Psalms has produced a substantial volume of li
This master thesis explores the concept of ecosystem services, in the context of urban planning in Swedish municipalities, with the purpose of putting together a planning development tool for urban ecosystem services. The working process consisted of three steps: (1) to identify problems in the Swedish planning process, (2) to identify relevant aspects of ecosystem services and comprehensive plann
Considering the urgency in uniformity and harmonization of existing law relating to carriage of goods by sea, the Comité Maritime International (CMI) initiated a joint project with UNCITRAL to achieve more uniformity and to replace the Hague, Hague-Visby and Hamburg Rules which are outdated by now and cannot fully satisfy the needs of modern multimodal transport. The result of this joint project b
Economic sanctions - the exercise of pressure by one international actor to produce a change in the political behaviour of another international actor - are instruments used in the exercise of foreign policy. Due to the perceived ineffectiveness of traditional economic sanctions, such as trade embargoes, a new type of sanctions has emerged. Unlike economic sanctions in the traditional sense, these

We exhibit supercritical trade-off for monotone circuits, showing that there are functions computable by small circuits for which any small circuit must have depth superlinear or even super-polynomial in the number of variables, far exceeding the linear worst-case upper bound. We obtain similar trade-offs in proof complexity, where we establish the first size-depth trade-offs for cutting planes an
This thesis, comprising four research papers, contributes to the field of systematic and computer-aided analyses and design of first-order methods. The first two papers focus on developing new methodologies, while the remaining two apply these techniques to refine complexity and convergence results, as well as to design new methods. A central theme of the work is the use of Lyapunov-type analyses,
Channel sounding is a vital step in the design and deployment of wireless communication systems. In this article, we present the design and implementation of a coherent distributed massive multiple-input-multiple-output (MIMO) channel sounder operating at 5 and 6GHz with a bandwidth of 400MHz based on the NI USRP X410. Through the integration of multiple transceiver chains and radio frequency (RF)
