Post-quantum cryptography increases the computational and data-movement demands placed on embedded processors. Many standardized and candidate schemes rely heavily on Keccak, SHA-3, and SHAKE operations, where the 1600-bit Keccak state is repeatedly updated and may become a bottleneck when accelerated through software-hardware interaction. This thesis presents a direct memory access (DMA)-enhanced
As buildings become more energy-efficient in their operation, the environmental costs of building components, such as carbon emissions during manufacturing, transportation, and end-of-life, are becoming increasingly significant. Automated façade shading systems have been widely proposed for their ability to reduce operational energy use and improve daylight performance. However, their life-cycle e
In an era of rapid change and increasing societal demands, the role of universities as knowledge producers and catalysts for change has come under scrutiny. This open access book offers a fresh perspective on the significance of universities in society, shedding light on how their knowledge can truly matter beyond academia.Drawing upon insightful inquiries from both the Swedish and international c
The thesis addresses inventory planning in a multi-site food manufacturing network where inventory decisions are currently made using differing local routines, planning parameters, and levels of analytical support. The single- company case study is conducted at a bakery subsidiary of a large agricultural cooperative based in northern Europe that operates over 30 bakeries. As a result of recent bak
As industrial sectors and digital infrastructure expand, the global demand for high-volume, reliable manufacturing of thermal management solutions like heat exchangers continues to accelerate. This thesis investigates the design and optimization of an automated robotic assembly cell for heat exchanger production at Alfa Laval using Discrete Event Simulation (DES). The primary objective was to defi
Mobile connectivity is set to change in the coming years due to AI generated data from agents and robotics. How this will develop remains uncertain since this type of data generation is not only a question of connectivity but also compute location and use cases. This creates a need for forward looking scenario analysis for ecosystem players so they can position themselves to win in a new paradigm.
Title: Exploring Rush Order Policies in a Multi-Echelon Inventory System Authors: Stina Nilsson & Lina Solbu. Supervisors: Johan Marklund, LTH. Philip Mårtensson & Johan Lidvall, Volvo Group. Background: The Case Company is currently transitioning their inventory control from a single-echelon to a multi-echelon optimization approach. As no formal rush order policy currently exists, it i
This thesis, conducted in collaboration with Trelleborg AB, investigates sourcing decisions for metal components within the Anti-Vibration Solutions business unit. The study addresses the challenge of evaluating sourcing alternatives across Europe and Asia-Pacific, where differences in cost, lead times, risk exposure, and sustainability create complex trade-offs. The purpose is to develop a practi
Cleanrooms in the pharmaceutical industry are energy-intensive environments where HVAC systems account for roughly 50-75% of energy use due to high air changes per hour and strict conditioning requirements for indoor humidity and temperature. This thesis presents a techno-economic analysis comparing two of the most common HVAC system types. These systems are centralized, using one large AHU to pro
The revised Energy Performance of Buildings Directive (EPBD) strengthens the regulatory framework for improving the energy performance of the existing building stock in the European Union. In Sweden, the implementation of the directive is particularly relevant for residential buildings with low energy performance, especially buildings in energy classes F and G. This thesis examines how the revised
The recast Energy Performance of Buildings Directive introduces binding Minimum Energy Performance Standards for existing non-residential buildings, requiring Member States to identify and renovate the worst-performing segments of their building stock. This study develops and applies an integrated framework for evaluating energy renovation measures in office buildings, addressing building category
The goal of this thesis was to investigate the path-length dependence of jet suppression for jets propagating through a medium known as the quark–gluon plasma (QGP). The QGP is formed in collisions between two lead (Pb) ions, where the overlap region consists of participant nucleons distributed in an approximately elliptical geometry. Simulations of jet quenching in these collisions were performed
Föreställ dig en värld där vi kan få information om ett objekt på flera meters avstånd utan att behöva gå nära det. Objektet kanske är något vi stör om vi kommer för nära, som en insekt, eller så är det något farligt, som avgaserna från en raket. Faktum är att vi kan göra precis detta idag – med hjälp av lasrar. Vanligtvis skickar forskare laserljus mot objektet, som absorberar det och skickar tilThere exists a lack of laser-based remote sensing methods that give signals with high intensity and directionality. According to previous research, mirrorless lasing can meet these requirements; however, neither the dependence on the gain medium geometry nor the light-matter interaction responsible for the emission has been investigated in detail. This thesis project examined the sideways lasing e
Few-cycle laser pulses are fundamental for tracking ultrashort motions such as electron dynamics and achieving stronger fields. They are also extensively used to perform high-harmonic generation and in attosecond science. However, generating stable and high quality few-cycle pulses requires a simultaneous control of bandwidth and dispersion. The generation of few-cycle pulses in an efficient manne
Wildfires are a natural disturbance shaping boreal forests, but their effects on soil microbial communities and biogeochemical cycling remain unclear, particularly in Fennoscandia. We investigated the impact of fire severity and post-fire management on the soil microbial community two years after a boreal wildfire in Sweden. We quantified growth rates of bacteria, saprotrophic fungi (SF), ectomyco
Water management is a critical factor for the performance and reliability of polymer electrolyte fuel cells (PEFCs) operating as energy generation systems. Inadequate operating conditions may lead to non-uniform water distribution, resulting in membrane dehydration or flooding of porous media, both of which adversely affect cell operation. In this work, a two-dimensional reduced-order model is dev
A real-time optical imaging system has been developed and commissioned at the European Spallation Source (ESS) to monitor the high-power proton beam at the tuning beam dump, and provide machine protection. The system employs chromium-doped alumina (Chromox) luminescent screens imaged by radiation-shielded optics and a CMOS camera. Real-time FPGA-based processing extracts beam size and position, de
SLAM is one of the biggest bottlenecks of XR devices, which have strict requirements for latency, power consumption, and user satisfaction. A solution that has been proposed and studied to meet the requirements is to offload SLAM to a remote server, which leverages computational hardware but may suffer due to incurred delays and transmission power. In this work, we propose offloading SLAM using Ma

Research on degrowth has burgeoned in the last 15 years but one of the greatest challenges is its relevance for and potential to build fruitful alliances with the Global South. Articulations of degrowth as an alternative are often associated with nourishing autonomous grassroots initiatives, relocalizing economies, as well as transforming institutions and policies in the Global North. However, thi
