This Licentiate Thesis is devoted to inventory control theory, a subdiscipline within the field of operations research and the management sciences. The objective of the research presented is: To develop mathematical models for efficient control of stochastic multi-echelon inventory distribution systems,
AbstractDead standing trees (DSTs) generally decompose slower than wood in contact with the forest floor. In many regions, DSTs are being created at an increasing rate due to accelerating tree mortality caused by climate change. Therefore, factors determining DST fall are crucial for predicting dead wood turnover time but remain poorly constrained. Here, we conduct a re-analysis of published DST f
The paper presents novel studies on the impact of different ignition control parameters on combustion stability and spark plug wear. First, experimental results from a 32.4-liter biogas fueled large bore single cylinder spark ignition engine are discussed. Two different ignition systems were considered in the experiment: a DC inductive and an AC capacitive. The spark plugs used in the experiment w
In the present era of evolving gene-based therapies for inherited retinal dystrophies (IRDs), it has become increasingly important to verify the genotype in every case, to identify all subjects eligible for treatment. Moreover, combined insight concerning phenotypes and genotypes is crucial for improved understanding of thevisual impairment, prognosis, and inheritance. The objective of this study

The objective of this study was to examine short- and long-term healthcare resource utilization and associated costs after ostomy creation. Methods: This observational study was based on retrospectively collected data from national and regional Swedish registries. The population consisted of peopl
European forests are among the most extensively studied ecosystems in the world, yet there are still debates about their recent dynamics. We modeled the changes in tree canopy height across Europe from 2001 to 2021 using the multidecadal spectral data from the Landsat archive and calibration data from Airborne Laser Scanning (ALS) and spaceborne Global Ecosystem Dynamics Investigation (GEDI) lidar
OBJECTIVES: Evidence on waning patterns in protection from vaccine-induced, infection-induced, and hybrid immunity against death is scarce. The aim of this study is to assess the temporal trends in protection against mortality.METHODS: Population-based case-control study nested in the total population of Scania Region, Sweden using individual-level registry data of COVID-19-related deaths (<30 day
Meta Isæus-Berlin: The Animated Installations Torsten Weimarck At about the same time that I saw Meta Isæus-Berlin’s remarkable installation Ett vattenhem (A Water Home) at the Bo01 Housing Fair in Malmö I also happened to see Johannes Stjärne Nilsson and Ola Simonsson’s film Music for one appartment and six drummers which was shown as a supporting film in the cinema. It struck me that these wo
Denna uppsats syftar till att utreda gällande rätt kring det offentliga biträdets roll i LVU-processen. Framställningen görs ur ett barnrättsperspektiv med ändamålet att utreda huruvida processen i LVU-mål är likställd mellan å ena sidan socialnämnden, å andra sidan den unge och dennes vårdnadshavare. För detta syfte förekommer även inslag av ett komparativt perspektiv samt ett utvecklingsperspektThis thesis seeks to investigate applicable law concerning the public counsel in the process according to The Care of Young Persons (Special Provisions) Act (LVU). The thesis is written from a children’s rights perspective with the purpose of investigating whether the process is equal between the social welfare committee on the one hand, and the child on the other. When the social service needs
Surveillance cameras are vital in the nuclear power industry where the reactor equipment must constantly be kept under surveillance to maintain safety. Constant monitoring is however difficult due to the highly radioactive environment, which cause cameras to malfunction and eventually break. Malfunction typically manifests itself as quality degradation of the image from the cameras. Initially, tem
A wave atlas describing the monthly wave climate at 5 locations along the Swedish SE coast was desired. Using the WAM wave model to hindcast the waves between Jan 1st 2004 and Dec 31st 2009 the parameters significant wave height, direction of wave propagation and spectral wave peak period were extracted from the time series and assembled in a wave atlas. The model was forced with point source wind
Background: Theory of warehouse operation are a well explored area but it seems that warehouse manager have a hard time to understand what solutions to adapt to improve their warehouse. Theory of Constraints(ToC) are a young philosophy regarding improvements work that have been employed to many different business areas. Warehouse manager would need a method to evaluate what solutions to implement
Crystallization of amorphous lactose during storage at high relative humidity and high temperatures has been found to impair the quality of skim milk powders. This is related to the glass transition of lactose. Above a certain temperature (glass transition temperature) amorphous lactose transfers through the rubbery zone into a crystalline state due to increased molecular mobility and as a result
The purpose of this study was to examine how external job-coaches consider themselves to perform their entrusted tasks from both the Employment Service's requirements and the jobseekers' needs and expectations. The empirical material consisted of seven semi-structured interviews with job-coaches from different private companies in southern Sweden. Based on the interviews we were able to fi
Täppt näsa, halsont och nysningar är symtom du säkert har upplevt vid en förkylning. Förkylningar är vanligast under våren och hösten och orsakas oftast av Rhinovirus. Även om en förkylning oftast är en lindrig åkomma för de flesta så kan den ha allvarliga konsekvenser för personer med nedsatt immunförsvar eller underliggande sjukdom. Förkylning sprids via direktkontakt, indirekt kontakt (såsom Airborne viral diseases have long been neglected but with the recent devastating impact of the COVID-19 pandemic serving as a catalyst for new science, additional viruses are examined. This thesis investigates the infectivity of Rhinovirus, the virus causing common cold, in differently sized bioaerosols. The experimental setup utilized a bio-aerosol nebulizing generator (BANG) to generate droplets
Människan har drömt om liv bortanför jorden, även innan upptäckten av den första exoplaneten runt en solliknande stjärna år 1995. Idag, med över 5600 bekräftade exoplaneter, är möjligheterna om liv på en annan planet bortom vår fantasi. Men innan vi ens försöker förstå oss på utomjordiskt liv, så måste vi förstå vad dessa planeter består av. Planeter och deras världsstjärnor är sammankopplade då dExoplanets and their host stars are intrinsically related as they form from the same accretion disc, and are therefore expected to have similar chemical composition. Thus, knowing the composition of exoplanet host stars is important for developing planetary formation and migration theories. There has been a recent uptick in studies of ultra-hot Jupiter atmospheres as their orbital configurations p
Med en ökande befolkning ökar även behovet av bostäder. Genom ombyggnation av befintliga äldre byggnader kan man ge de boende en modern standard och minska energianvändningen. Att återbruka byggnader ger oftast ett mer hållbart byggande med mindre avfall och koldioxidutsläpp jämfört med att riva och bygga nytt. Syftet med denna fallstudie är att undersöka hur en industribyggnad som uppfördes 1952 With an increasing population, the demand for housing also increases. Due to renovation and retrofitting of the housing stock it is possible to give the future resident a modern housing and at the same time reduce the energy demand for the building. Reusing buildings is often a more sustainable way to develop housing because it results in less waste and lower carbon dioxide emissions compared to d
