Although 6G is not only about higher data rates, its envisioned peak data rate of 1 terabits per second requires larger frequency bandwidth than what 5G millimeter wave bands offer. Therefore, new frequency bands have been allocated in the sub-THz range for 6G applications. This paper reviews the concept of distributed deployment to provide coverage in sub-THz bands, focusing on the design and imp
The unquenchable thirst for bandwidth to support next-generation wireless systems is increasingly bringing D-band into the spotlight. This work proposes a scalable D-band patch antenna that features both coplanar and stacked parasitic patch structures. By leveraging inter-patch coupling, different coplanar parasitic elements are excited across different frequency bands, enabling multi-mode operati
Sin ringa storlek till trots har insekter enorm inverkan på vårt samhälle och våra liv. Bin, som är centrala för att vårt jordbruk ska fungera, har minskat drastiskt i antal de senaste åren. En utbredd bidöd skulle i bästa fall tvinga oss lägga om vår kosthållning markant, och i värsta fall leda till svält. Utöver detta skulle växter som är beroende av bin för sin fortplantning och djur som äter bThis thesis treats entomological lidar from various angles: laboratory reference work on insects of interest, methodological development of lidar- and data processing methods, as well as field implementations of lidar techniques for entomological research. Insects are crucial components of ecosystems and are currently in a global decline. In this thesis, insects are mainly studied in their roles a
Today’s society promises that people with disabilities can access anything, but in practice there are numerous obstacles, and the ways in which people deal with them can be easily missed or taken for granted by policy makers. This article draws on a project in which researchers ‘go along’ people with disabilities in Sweden who demonstrate and recount accessibility troubles in urban and digital set
This deliverable provides the theoretical underpinning of the NEWCOMERS project, including the key concepts and definitions as well as the formulation of research propositions in order to enhance the project’s coherence. To this end, it develops a novel theoretical framework based on polycentric governance theory, combined with elements from socio-technical systems theory, social innovationtheory,
Robotic systems for manipulation tasks are increasingly expected to be easy to configure for new tasks. While in the past, robot programs were often written statically and tuned manually, the current, faster transition times call for robust, modular and interpretable solutions that also allow a robotic system to learn how to perform a task. We propose the method Behavior-based Bayesian Optimizatio
The increase in electric vehicles has led to more vehicles of this kind being involved in accidents. Since there is a risk of a delayed initiation of thermal runaway in these cases, many countries have recommendations for safety distances from crashed vehicles to buildings. This report is a part of the effort to develop similar guidance for Sweden, which was initiated by the Swedish Civil ContingeThe increase in electric vehicles has led to more vehicles of this kind being involved in accidents.

When developing general-purpose robot software components, we often lack complete knowledge of the specific contexts in which they will be executed. This limits our ability to make predictions, including our ability to detect program bugs statically. Since running a robot is an expensive task, finding errors at runtime can prolong the debugging loop or even cause safety hazards. This paper propose
Near-field focusing (NFF) is a fundamental enabler for a broad spectrum of applications utilizing large intelligent surfaces (LIS) within sub-10 GHz frequency bands. This paper investigates the impact of element pattern on NFF properties, when the LIS array is a large planar array. The NFF properties of maximum received power, focal width, and focal depth are analyzed for three typical antenna pat
This article presents new estimates of the material living standards among the rural population in southern Sweden from the 1670s up to 1865.

The aim of this working paper is to expand the range of pedagogical tools for teaching statistics to social work students, by introducing an innovative tool that is based on the factorial survey and intended for practicing statistical analysis. The factorial survey, which was pioneered by the American sociologist Peter Rossi around 45 years ago, involves the use of experimentally constructed ficti

The Freedom Theatre is one of the most remarkable institutions in occupied Palestine, and indeed the world. Nestled in Jenin refugee camp in the West Bank, the theatre has faced attacks, threats, imprisonment of many functionaries, and the assassination of its co-founder. And yet the theatre has not only endured, it has grown, from a provisional hall with rented plastic chairs to one of Palestine'The Freedom Theatre is one of the most remarkable institutions in occupied Palestine, and indeed the world.

The landscape of healthcare is experiencing a digitalization shift, transferring many medical activities to the patients’ homes, a phenomenon commonly referred to as Hospital-at-Home. While Internet of Things (IoT) devices facilitate the building of such systems, there is a need for powerful middleware that encapsulates device-to-device communication, and enables the construction of user-friendly,
The Storage Location Assignment Problem (SLAP) has a significant impact on the efficiency of warehouse operations. We propose a multi-phase optimizer for the SLAP, where the quality of an assignment is based on distance estimates of future-forecasted order-picking. Candidate assignments are first sampled using a Markov Chain accept/reject method. Order-picking Traveling Salesman Problems (TSPs) ar
Massive multiple-input multiple-output (MIMO) plays an important role in beyond 5G systems to support high data rate and low latency, especially operating at millimeter-wave frequency bands. In traditional software-based simulators, the simulation time increases exponentially with the number of base station antennas and served users. We propose a hardware-in-loop simulator that combines the flexib
Massive multiple-input multiple-output (MIMO) technology will continue playing an important role in beyond 5G wireless systems. Fully digital beamforming at the millimeter wave (mmWave) spectrum enables applications that require high data rates and low latency. This paper investigates the development and deployment of mmWave massive MIMO systems in an in-flight cabin environment, from both system
The Storage Location Assignment Problem (SLAP) is of central importance in warehouse operations. An important research challenge lies in generalizing the SLAP such that it is not tied to certain order-picking methodologies, constraints, or warehouse layouts. We propose the OBP-based SLAP, where the quality of a location assignment is obtained by optimizing an Order Batching Problem (OBP). For the
