In the software industry, the drive to add new features often overshadows the need to improve existing code. Large Language Models (LLMs) offer a new approach to improving codebases at an unprecedented scale through AI-assisted refactoring. However, LLMs come with inherent risks such as braking changes and the introduction of security vulnerabilities. We advocate for encapsulating the interaction

In this paper, we present a new framework for improving soil strength using an advanced method of engineering statistics. The materials included clay till collected in Yttre Ringvägen, southern Sweden. Binders included quicklime, slag and ordinary Portland cement used as pure binders and blended mixtures. We first applied the Response Surface Methodology techniques aimed at binder blend optimisati
Analysis of structures subjected to moving loads is presented. In particular, structural effects due to structure-vehicle interaction are studied. The basic equations of the structure-vehicle system are derived by means of continuum mechanics, the finite element method and multibody dynamics.In order to consider the interaction between structure and vehicle in a straightforward way, a special stru
Surface crack width is regulated in codes to limit corrosion of reinforcement bars in concrete. However, the influence of surface crack width on corrosion damages is not directly inferable from previous research.In this work, data on corroded cracked concrete specimens in chloride environments was compiled. Detailed information was included, such as crack and pit locations, local corrosion pattern
Control of the microstructure of steel components during their processing is a crucial factor for reaching desired product properties. Realistic simulations of the microstructure evolution during processing can facilitate the improvement of existing processes as well as the design of new ones by reducing the need for time- and cost-intensive experimental investigations. This work focuses on the mo
Little is known about whether exposure to unconventional oil and gas development is associated with higher mortality risks in the elderly and whether related air pollutants are exposure pathways. We studied a cohort of 15,198,496 Medicare beneficiaries (136,215,059 person-years) in all major US unconventional exploration regions from 2001 to 2015. We gathered data from records of more than 2.5 mil
Progressive myoclonic epilepsies (PMEs) comprise a group of rare disorders of different genetic aetiologies, leading to childhood-onset myoclonus, myoclonic seizures and subsequent neurological decline. One of the genetic causes for PME, a mutation in the gene coding for Golgi SNAP receptor 2 (GOSR2), gives rise to a PME-subtype prevalent in Northern Europe and hence referred to as North Sea Progr
We present novel coupling schemes for partitioned multiphysics simulation that combine four important aspects for strongly coupled problems: implicit coupling per time step, fast and robust acceleration of the corresponding iterative coupling, support for multirate time stepping, and higher-order convergence in time. To achieve this, we combine waveform relaxation—a known method to achieve higher-
This work describes the research conducted in order to assess possible changes and uncertainties in future energy performance of the residential building stock in Stockholm. The investigation is performed on a sample of 153 existing and statistically selected buildings and covers the period of 1961-2100. Four uncertainty factors of the climate have been considered: global climate models, regional
It is known that shading systems often combined with solar control glasses are used to avoid glare and overheating at expenses of daylight. In Dynamic Thermal Modelling tools, there is no assessment method where the shading use is expressed when predicting the building performance. Furthermore, literature often refers to studies where complex fenestration systems are optimized for specific cases.
Proteins are complex molecules, present in all of the vital functions of life. The function of a protein is regulated by interactions between protein and other molecules. Drug design in pharmaceutical science aims to regulate the function of a protein by the design of synthesized molecules that binds to a protein with high affinity. A change in protein flexibility upon ligand binding can provide s
Popular Abstract in SwedishUnder slutet av 1950-talet, ungefär samtidigt med tv:s etablering, innehade Sverige Europarekordet vad gäller antalet biografer. Folk gick på bio som aldrig förr. Biograferna att spela en mycket stor roll för film- och biografkulturens tillgänglighet och spridning. Den här boken handlar om att gå på bio. Genom att gå på bio lärde sig människor att se och uppleva film ochGoing to the Pictures The Cinema as a Meeting Place in the 1940s and 1950s Summary At the end of the 1950s, at roughly the same time as television became established, Sweden had the largest number of cinemas of any country in Europe. People went to the cinema in unprecedented numbers. In 1956 ticket sales in Swedish cinemas reached 80 million. There were palatial cinemas which offered people a f
Recently, internal combustion engine design has been moving towards downsized, more efficient engines. One key in designing a more efficient engine is the control of heat losses, i.e., improvements of the thermodynamic cycle. Therefore, there is increasing interest in examining and documenting the heat transfer process of an internal combustion engine. A heavy-duty diesel engine was modeled with a
Studier har visat att tvåfasflöde med gas och vätska kan öka ett membrans flux. I detta examensarbete har två vätskor, kiseldioxidlösning och hemicellulosalösning, luftats med olika metoder, och luftningens inverkan på fluxet har studerats. När vätskor med hög viskositet ska membranfiltreras är ofta fluxet lågt vilket gör att filtreringen tar lång tid och att det därför behövs stora membrananläggA new oxygen barrier film that is made of arabinoxylan has been developed by the company Xylophane. Arabinoxylan is available among other things in wheat bran. But a problem with the method of extracting the arabinoxylan is that after an alkali extraction is ultrafiltration used to remove impurities and the flux during this is quite low. In this project is it investigated if gas sparging with air
Att effektivisera program som löser komplexa problem har länge varit ett av målen inom beräkningsvetenskapen. I denna kandidatuppsats så undersöker vi ett sätt att göra program mer effektiva, och det är med hjälp av vektorisering. Detta är en metod som tidigt i beräkningsvetenskapen var central för att göra program mer effektiva. Senare blev andra former av parallelisering mer central, men det finVectorization has been an important consideration for scientific com- puting performance for a long time. Early super computers were designed around vectorization, the so called ”vector computers”, but recent trends point toward favouring other computer architectures, and vector comput- ers are much more rare than they used to be. Nonetheless, vectorization still lives on to a smaller extent in mo
Modelica-TM is an object-oriented language for modeling physical systems that was designed in the last years with the goal to become a standardized multi-domain modeling language. This paper describes a robust model for homogenous and inhomogenous two phase flows with dynamic or static slip correlation. It was developed in the context of developing a Modelica base library for thermo-hydraulic appl
This thesis aims to investigate and implement a fault-tolerant energy-efficient RISC-V based system on chip (SoC). Key features of the SoC is the testabil- ity and reliability of the low power on-chip embedded memories. A built-in self- test (BIST) for the on-chip memories has been designed and implemented to run on-demand diagnostic tests to detect manufacturing errors in the memories. It incor
This thesis examines the blog ‘Alla Dessa Dagar’ by the Swedish Minister of Foreign Affairs Carl Bildt; one of the pioneer politicians using social media to broadcast political messages. Based on role theory and theories covering social media, with capacities of democratization and blurring between public and private, the focus of the study is twofold. To begin with the study aims to identify how
