In this paper we study the propagation problem of a time harmonic electro- magnetic field inside a cavity filled with a generic bianisotropic medium. We define the concepts of eigenfrequencies and modes of the cavity and we prove their existence and countability. We extend, in this respect, the theory for the isotropic, homogeneous, lossless cavity.

This submission is devoted to optimization of networks that permanently experience fluctuations of the capacity available on their links. This is an important and novel topic since limited link availability is a fundamental feature in wireless networks and yet majority of work in survivable network design is restricted to the total single link failures. We assume a given finite set of network stat

This dissertation aims to investigate the social situation at school for students that have migrated to Sweden during their last four years at compulsory school or during upper secondary school. The study investigates the social interaction between students with a special focus on the possibilities and hindrances for inclusion of the newcomer immigrant students in different groupings at school, an

In recent years, as 6G wireless systems continue to develop, high-accuracy indoor localization has become increasingly important for future wireless systems. At the same time, reliable indoor positioning is needed by many location-aware applications, such as robotic navigation, emergency healthcare, and smart transportation. Since indoor wireless measurements can vary over time due to multipath pr

HTTP-klienter används för att hämta data från servrar över ett nätverk. Det existerar flera olika användningsscenarier för dessa klienter. Detta examensarbete fokuserar på och undersöker användningen av tre olika HTTP-klienter i ett Spring Boot-system ur ett implementerings- och prestandaperspektiv. Systemet som användes var en mock-up skapad av IKEA för att efterlikna deras faktiska produktionssyHTTP clients are used to gather data from servers over a network. Several different usage scenarios for HTTP clients exist. This thesis focused on and investigated the usage of three different HTTP clients in a Spring Boot system from the perspective of implementation and performance. This system was a mock-up made by IKEA to mimic their real live Spring Boot system. The research focused on compar

Wind damage is one of the most economically and ecologically significant natural disturbances in European forests, yet the cloud cover that follows major storms routinely blocks optical satellite acquisitions for weeks, precisely when rapid damage mapping is most valuable. Synthetic aperture radar (SAR) circumvents this limitation through all-weather imaging, but pixel-level windthrow detection fr

Innovation concentrations are increasingly extending beyond metropolitan cores into urban peripheries through science parks, research infrastructures, advanced manufacturing sites, and innovation districts. Yet their physical presence does not necessarily generate long-term local development capacity. Existing research has explained innovation stability largely through agglomeration, proximity, in

In multi-view sports broadcasting, extracting high-quality highlights and selecting the optimal camera angle from concurrent video streams is traditionally a labor-intensive process with significant computational overhead. This thesis explores the feasibility of automating the production of multi-view sports highlights using Multimodal Large Language Models (MLLMs). To manage the high computatio

Long-term university–industry strategic partnerships require continuous coordination across multiple activities, focus areas, roles, and governance levels. Using the Tetra Pak–Lund University (TP–LU) partnership as the empirical setting, this thesis aims to design a strategic partnership dashboard for governance support and to develop design-oriented knowledge for shared dashboard use in similar l

Patient-specific fluid-structure interaction (FSI) simulations can improve the understanding of mitral valve dysfunction and support preoperative planning. However, existing contracting left ventricular (LV) FSI models are often computationally demanding which limits their clinical applicability. This thesis addresses these limitations by developing a patient-specific contracting LV model within a

Traditional football analytics largely evaluates players through on-ball events such as shots, passes and dribbles, leaving the much longer periods of off-ball play poorly measured. This thesis develops a spatial framework for evaluating individual player contributions in crossing situations, where a cross is defined as an aerial or driven delivery from a wide area into the central penalty zone. T

Damaged or partially damaged pumps can cause issues that at best is an inconvenience and at worst a catastrophe. In order to prevent such issues it is necessary to catch any potential damage as early as possible. One possible solution is to use a sensor that can be placed on or near a pump in order to monitor it using audio. Audio based fault detection is still a relatively new field of research,

Preterm infants benefit from combined supplementation of arachidonic acid (ARA), docosahex-aenoic acid (DHA) and choline, but ARA/DHA-rich oils are highly susceptible to lipid oxida-tion. This project aimed to develop and evaluate choline-enriched DHA/ARA oil-in-water emulsions with suitable physical and oxidative stability. Emulsions were prepared by high-pressure homogenization using two AquaCel

Therapeutic peptides are a fast-increasing segment in the pharmaceutical industry, and GLP-1 analogues stood for two out of the three most sold drugs last year, 2025. The most common production method of peptides is based on Merrifield’s discovery of solid-phase peptide synthesis (SPPS), which uses large volumes of hazardous chemicals like N,N-dimethylformamide (DMF), piperidine, and trifluoraceti

Denna studie undersöker hur rollen som kommunal beredskapssamordnare konceptualiseras i kommunala rekryteringsannonser. Genom en kvalitativ innehållsanalys av 30 annonser analyseras vilka kunskaper, kompetenser och arbetsuppgifter som tillskrivs rollen. Resultatet visar att beredskapssamordnaren framställs som en hybridroll där specialistkunskap inom civil beredskap kombineras med generella kompet

Brädspel blir alltmer populära, vilket gör det ännu viktigare att deras regelböcker går att läsa och förstå. Denna uppsats syftar till att analysera språkbruket i strategiska brädspel i förhållande till klarspråk och forskning om instruerande text, men också att undersöka spelarnas uppfattning om spelens regelböcker. Metoden för undersökningen består av en textanalys av spelen Terraforming Mars, R

Today, digital pre-distortion (DPD) is the predominant technique for linearising the power amplifiers (PAs) used in telecommunication radio transmitters. However, conventional DPD implementations rely on power-hungry digital signal processing, making energy efficiency a critical concern. Compute in-memory (CiM) architectures have previously been demonstrated to provide significant efficiency gains
