As our way of living exploits the resources of the earth and our energy use keeps on increasing, we are now facing a climate crisis never seen before in modern time. To face these consequences and try to ease the harm we need to transform our extraction and use of energy. The use of chemical energy carriers and fuel cells offers the possibility of a completely green solution for energy distributio
Japanese knotweed, Reynoutria japonica, is a highly invasive alien species which has spread in Europe and America since it was introduced in the middle of 1800. Its ability to outcompete and suppress native plants and combined with its resilience and regenerative properties makes it difficult to control. Therefore, multiple methods have been tried to control this plant, but with varying success. T
Problem definition Nowadays society is very concerned with sustainability. Companies try their best to meet sustainability customers’ expectations and regulations. The adoption of Lean and Six Sigma could bring sustainability improvements, but it is not clear how these three areas are combined and how they are currently addressed by companies. Purpose Explore the relationship between Lean, Six Sig
Denna studie har genomförts på Tetra Pak för att studera deformation i vätskekartong under vikning. När en förpackning formas i fyllmaskinerna viks kartongen enligt biglinjerna. Det finns ett stort intresse av att studera vikprocessen då den är avgörande för den slutgiltiga kvaliteten av förpackningen. Matematiska modeller används för att simulera kartong men dessa kräver verkliga mätningar och dThis study has been conducted at Tetra Pak to study deformation in liquid packaging paperboard during the folding process. When a package is formed in the filling machines, the paperboard is folded according to the crease lines. It is of great interest to study the folding process since it is crucial to the final quality of the package. Mathematical models are used for simulation of paperboard bu
This thesis explores the correlation between national role conceptions, national identities and sensemaking processes among South Korean and Swedish policy influencers during the Sunshine Policy years of 1998-2003. The study relies on in depth semi structured interviews with 10 policy influencers who work with North Korea policies. Starting from Holsti’s (1970) national role conceptions and Weick’
I en allt mer globaliserad värld och efter den digitala revolutionen, har skyddet för personuppgifter hamnat i rampljuset. Numera, utbyts data över nätet dagligen för olika syften, såsom privata, kommersiella och allmänna, vilket har skapat en oro för hur dessa överföringar av personuppgifter kan påverka rätten till dataskydd och rätten till privatliv. Inom EU har det funnits en tradition av att In an increasingly globalized world and after a decade of digital revolution, the protection of personal data has fallen in the limelight. Nowadays, data is exchanged over the internet daily for various purposes, including strictly private, commercial, as well as public, which has raised concerns on how these transfers of personal data may affect the right to data protection and the right to priva
Due to increasing awareness and consumer demands it has become important for companies to develop an economical and environmentally sustainable alternative to traditional petroleum-based plastics. The transition from fossil material to bio based is important for the future of people and planet, still, how the transformation should be implemented is yet unknown. In this report, the possibilities of
The Large Hadron Collider (LHC) at CERN is undergoing a major upgrade to prepare for the High-Luminosity LHC. It will allow for many more particle collisions to occur. Some detectors that make up the LHC experiments must be replaced to withstand the harsher conditions. In particular, the inner tracking detector (ID) of the ATLAS experiment will be replaced by the new Inner Tracker (ITk). Every co
Due to increasing global energy demands and a need to move away from non-renewable energy sources, green hydrogen is now being considered as a possible replacement for fossil-based energy sources. Especially in “hard-to-abate” sectors, such as steel and petrochemical production, and long-distance transport, where the change to renewable electricity is more difficult. Green hydrogen is produced thr
A lack of somatostatin expressing interneurons (SST INs) is known to be a factor in several neurodegenerative and neurospsychiatric diseases, such as Alzheimer disease, Parkinson’s disease and schizophrenia. Being able to efficiently obtain SST INs in vitro could enable a greater understanding and better treatment of these diseases. The development of SST INs is not yet fully understood, but it is
The use of antenna arrays allows for direction-of-arrival (DoA) estimation in a radar system. The antenna elements in an array are conventionally positioned equidistantly on a grid, but they can also be placed relatively freely to form sparse antenna arrays. These non-conventional layouts could potentially offer improved DoA capabilities. In this work, a particle swarm optimization algorithm has b
High-Level Synthesis(HLS) is a design methodology that enables designers to implement hardware from high-level coding languages, such as C, C++, or System C. It provides designers with the ability to convey their design at a higher level of abstraction, which allows more emphasis on an algorithm and functional aspects of design instead on low-level hardware details. As precise control of signal ti
The pine sawfly Neodiprion sertifer (Geoffroy) uses the acetate or propionate of (2S,3S,7S)-3,7-dimethyl-2-pentadecanol (diprionol) as pheromone components, with the (2S,3R,7R)-isomer being antagonistic, synergistic, or inactive according to the population tested. In this study, we tested the attraction of males to the acetates of three analogs of diprionol, each missing one methyl group, viz. (2S
Monitoring of glucose in subcutaneous and brain striatum have been extensively studied in the past. While biocompatibility was one of the limitations, others included the messy measuring equipments preclude monitoring in a complex environment. This study tried to establish an amperometric measurement of glucose in pre- and post-insulin-administration on diabetic and hyperglycemia rats via wireless
In this paper a fully coupled thermomechanical two-dimensional simulation model for orthogonal cutting is presented. The model is based on the arbitrary Lagrangian-Eulerian formulation with the remeshing technique. The material model used for the workpiece material includes Johnson-Cook plasticity, and as the chip separation criterion the Johnson-Cook damage law is employed. The different friction
