Cybersecurity engagement in a remote work environment
The recent spread of COVID-19 pandemic encouraged organisations to facilitate a remote work environment for their employees. This work environment would most likely continue in the upcoming years. At the same time, this context has been followed with an increase in cyberthreats that could affect the optimal processes of organisations. Because of this, cybersecurity awareness must be cultivated to
Predicting Acute Kidney Injury In Sepsis Patients: A Machine Learning Approach
Kan maskininlärning hjälpa oss förutspå njurskada i sepsispatienter? Årligen drabbas omkring 40000 människor i Sverige av sepsis och närmare 20% av dessa avlider som följd av sjukdomen. Trots detta är sepsis ett relativt okänt sjukdomstillstånd för allmänheten och även inom akademin är det ett relativt ostuderat område. Således finns det ett stort behov av en fördjupad förståelse av sepsis. SepsiSepsis-induced Acute Kidney Injury (AKI) is a common cause of death for sepsis patients, yet it is poorly understood by the medical community. Using Tandem Mass Spectrometry (MS/MS), the blood plasma of 135 sepsis patients has been analyzed to measure protein levels. In this thesis we will present an exploratory application of machine learning on this data, with the intent of producing a model wh

It's smart, but is it sustainable? A study of circular and social sustainability in smart grids.
Social hållbarhet viktigt för att nå resurseffektivitet i smarta elnät Vad är smarta elnät egentligen? Att svara på detta är inte helt enkelt, för det finns ingen exakt definition av begreppet. Det kan dock förklaras som att elsystemet digitaliseras och blir effektivare så att det bättre passar en framtid med mer förnybar och varierande elproduktion och ökad elektrifiering. I detta arbete har detSmart grids are often advertised as more environmentally sustainable compared to their “conventional” counterparts. What is highlighted then is their potential to save energy and integrate more renewables into the grid, thus decreasing CO2-emissions. This thesis investigates two less discussed aspects of smart grids, those of circular economy and social sustainability. An initial literature review
Riskhantering och cloud
De senaste årens tillväxt och framsteg inom cloud computing har medfört många fördelar ur ett organisatoriskt perspektiv. Företag har nu möjlighet att få åtkomst till pooler av datorresurser konfigurerade i form av servrar, lagring och nätverk, detta utan att behöva investera i dyr hårdvaruinfrastruktur. Det är dock viktigt att ta hänsyn till teknikens nackdelar och de svårigheter som kan uppstå.
Icke-farmakologiska åtgärder för att öka barns trygghet i samband med magnetisk resonanstomografi
Bakgrund: Magnetisk resonanstomografi (MR) relateras ofta till oro och ångest hos barn, bland annat på grund av det höga ljudet, trånga utrymmet och långa undersökningstiden, därav är sedering och generell anestesi vanligt förekommande. Barn har olika behov beroende på ålder och mognad därmed kan identifierng av icke-farmakologiska åtgärder behövas för att öka barns trygghet. Syfte: Att beskriva o

Moisture Transport in PA6
Polyamide 6 (PA6) is known to absorb water from its environment due to its chemical structure. The water absorption leads to changes in the mechanical properties as well as an increase in volume (swelling) of the polyamide. In this work, the sorption and diffusion of water vapor are investigated through gravimetric experiments and numerical simulations. The mixture theory framework is adopted to d

Factor Models for Futures Contracts to Improve Estimation of the Correlation Matrix
In this paper regularization of the correlation matrix between futures contracts is examined. With starting point in the recently established HPCA framework (Avellaneda, 2019), a couple of different extensions to the one-factor model is suggested. Extensions are made in terms of adjusting the model according to different cluster structures. The data consists of futures contracts on a wide variety

Översvämning av kyrkomiljöer - hur en ökad förekomst av översvämningar kan påverka kyrkomiljöer i Lunds stift
När syndafloden kommer När havsnivån stiger och nederbörden ökar riskerar upp till 29 utav Lunds stifts ca 500 kyrkobyggnader att drabbas av översvämningar. Detta betyder att behovet av skydd mot översvämningar troligtvis kommer öka för dessa miljöer i framtiden. Förekomsten av översvämningar förväntas öka till följd av klimatförändringen. Utav de ca 500 kyrkobyggnaderna i Lunds stift kan upp tThe occurrence of floods is expected to increase due to climate change, which may lead to destruction or loss of value of cultural heritage sites. There are approximately 500 church buildings in Lund diocese. The aim of this study was to investigate how this might affect the church buildings, their inventory, and cemeteries within Lund diocese, which are protected under Swedish law. The aim was al
