Friction stir welding (FSW) is a solid-state welding process where metals are joined without melting. Heat is generated by friction between a rotating non-consumable tool and the work-piece material, and by mechanical deformation of the material. The process, invented in 1991, provides several benefits over arc welding and other fusion processes: No filler material has to be added, low energy cons
Under tusentals år trodde människan att detta var Universums mittpunkt. Tack vare vår nyfikenhet, fantasi och lust att upptäcka, vet vi nu att planeter som vår Jord inte är särskilt ovanliga i kosmos. Solen är bara en vanlig stjärna bland hundratals miljoner andra i vår galax, Vintergatan.Med hjälp av världens mest kraftfulla teleskop kan vi utforska mer och mer av Universum. Det vi hittills har uFor thousands of years, mankind thought that this was the centre of the Universe. Thanks to our curiosity, imagination and urge to explore, we now know that planets like our Earth are nothing special in the cosmos. The Sun is just one ordinary star among hundreds of billions in our galaxy, the Milky Way.With the world’s most powerful telescopes, we are able to explore more and more of the Universe
Vi dyker tillsammans ner i tropiska hav och observerar tusentals färgglada fiskar simma förbi oss. Vi reser runt Jorden och undersöker olika typer av korallrev och de djur som där bor. Vi lär oss hur forskare tar fram nya metoder för att skydda och hjälpa Korallrevens Värld överleva nu när havstemperaturen stiger.Under vår resa upptäcker vi hur koraller lever, andas samt hur de förökar sig. KorallDive into a tropical ocean and see thousands of colorful fish flutter by. Travel the globe to explore coral reefs teeming with life and learn how scientists are racing to develop sustainable solutions to protect these vitally important ecosystems for the future. Along the way, discover how corals live, breathe, and reproduce, supporting a quarter of all marine life on Earth and providing critical
Högenergiastrofysik spelar en nyckelroll för vår förståelse av Universum. Den mest energirika strålningen avslöjar heta och våldsamma fenomen. Vi undersöker het gas i galaxhopar, som är de största och tyngsta objekten i Universum. Vi undersöker också het gas som samlas i skivor omkring supermassiva svarta hål i galaxers centra.Men högenergiastrofysik ger oss också viktig information om vår egen gaHigh Energy Astrophysics plays a key role in understanding the universe. These radiations reveal the processes in the hot and violent universe. High Energy Astrophysics probes hot gas in clusters of galaxies, which are the most massive objects in the universe. It also probes hot gas accreting around supermassive black holes in the centers of galaxies.Finally, high energy radiation provides importa
Graph cuts methods are at the core of many state-of-the-art algorithms in computer vision due to their efficiency in computing globally optimal solutions. In this paper, we solve the maximum flow/minimum cut problem in parallel by splitting the graph into multiple parts and hence, further increase the computational efficacy of graph cuts. Optimality of the solution is guaranteed by dual decomposit
A majority of the established systems for choice and optimization of cutting data are based on Woxén’s equivalent chip thickness, heW. In metal cutting theory and models, the equivalent chip thickness is of vital importance when the depth-of-cut ap is in the same order or smaller than the nose radius r. Woxén made considerable simplifications in his chip area model, that form the basis for calcula
Length and area regularization are commonplace for inverse problems today. It has however turned out to be much more difficult to incorporate a curvature prior. In this paper we propose two improvements to a recently proposed framework based on global optimization. The mesh geometry is analyzed both from a theoretical and experimental viewpoint and hexagonal meshes are shown to be superior. Our se
Xilinx FPGAs offer both Block SelectRAM and distributed RAM for embedded memory. To investigate the impact of utilizing such opportunities, some variations on the hardware implementation of a SNOW 2.0 stream cipher IP core have been designed. We find the ratio of throughput and effective slice usage to be close to 3.5. This allows a flexible trade-off between speed and area consumption, with a thr

An international network for threatened researchers Lund University has been a member of Scholars at Risk (SAR) since 2014. SAR is a network of over 500 member universities in 42 countries that supports and defends the principles of academic freedom and defends human rights for researchers around the world. The network also supports threatened researchers by arranging sanctuaries at the member uni

In May 2022, Karin Dalene Skarping started her PhD studies in TNU supervised by Prof. Åsa Petersén. The overall aim of the PhD project is to study genetic mechanisms that may modify the disease course and pathology of Huntington disease. One of her current research projects is aimed to examine associations between germline pathogenic variants in mismatch-repair (MMR) genes and CAG-repeats in HTT,
