This thesis investigated the prediction accuracy of offshore wind power using machine learning and classical time series methods. We used Support Vector Regression (SVR) with a Radial Basis Function (RBF) kernel along the Autoregressive (AR) model. Time series cross-validation with data from the Lillgrund Wind Farm and hyperparameter tuning were used to enhance the performance of both models. Thro

Favouring good soil health is pivotal for ensuring long term agricultural production by minimizing erosion, increasing soil carbon content, increasing the soil water holding capacity and decreasing the soil bulk density. Certain land management practices can disfavour factors for soil health and in-extent lead to soil degradation which can threaten food production and natural habitats. Soil organi

Jordbrukets matproduktion är helt nödvändigt för mänskligheten, samtidigt som det moderna jordbruket bidrar till en stor klimatpåverkan. Produktion av konstgödsel och bekämpningsmedel, dieseldrivna traktorer och skördetröskor och transporter orsakar en stor del av problemet, utsläppen från våra jordar en annan. Intensiv odling leder ofta till att organiskt kol som varit bundet i marken går förloraImproved management of agricultural soils to sequester carbon from the atmosphere is considered an important climate mitigation measure. Intensive agriculture often leads to degradation of soil organic carbon (SOC), contributing to climate change and loss of soil ecosystem services. Interventions in agricultural management can halt or reverse the loss of SOC. Annual SOC change rates for interventi

This thesis examines the integration and impact of Generative AI (GenAI) on UX design, emphasizing human-AI collaboration and task complexity. Utilizing AI Sensemaking and Actor-network Theory (ANT), the study reveals that GenAI tools have transitioned from experimental aids to essential components in the design process, significantly enhancing productivity, particularly in prototyping and idea ge

Manufacturing companies face mounting pressure to reduce inventory levels because of high interest rates, while simultaneously meeting an increase in customer demands for shorter lead times and customizable products, increasing strain on supply chains. The logistics department (SMCL) within Sandvik, the investigated company, operates several warehouses around the world. Their supplier network is b

Resilient backpropagation, Rprop, is a robust and accurate optimization method used in neural network training with batch-learning. As a result of its adaptive step sizes, Rprop requires copious amounts of data at each iteration which slows it down when dealing with large datasets, compared with mini-batch methods. We create and empirically evaluate a version of Rprop, S-Rprop, which can handle mi

This study examines how individual background factors in Italy influence employment quality, focusing on different labour market outcomes, namely income, employment duration, contract type, and part-time work using data from the Survey on Household Income and Wealth (SHIW). Results show that parental education and household wealth impact labour income, with wealth effects diminishing at higher inc

The aviation industry is under increasing pressure to mitigate its environmental impact, particularly concerning greenhouse gas emissions. Traditionally, commercial aviation has relied on conventional kerosene-based fuels. Recent advancements and environmental concerns have prompted the exploration of Sustainable aviation fuels (SAF), with initiatives like the Commercial Aviation Alternative Fuel

Sharenting, där föräldrar delar bilder av sina barn på sina sociala medieplattformar, är ett relativt nytt fenomen i världen av sociala medier, liknande en online version av det traditionella familjefotografiet. Det kan användas som ett passivt sätt att bjuda in geografiskt avlägsna nära och kära till invandrade mödrar och deras barns liv. Den här kandidatuppsatsen fokuserar på sharenting i sambanSharenting, where parents share pictures and videos of their children on their social media platforms, is a relatively new phenomenon in the world of social media, akin to an online version of traditional family photography. Sharenting can be used as a passive way of inviting geographically distant loved ones into the lives of immigrant mothers and their children. This thesis focuses on sharenting

De flesta associerar förmodligen ordet katalysator med bilkatalysatorer där smutsiga avgaser från fordon renas genom att gasen får reagera med syre och därmed bilda mindre skadliga produkter. Så kallade heterogena katalysatorer är ofta metalloxider och de används i många industrier för att möjliggöra kemiska reaktioner. Ett sådant exempel är Formox-processen, där en katalysator bestående av järnmoIn the Formox-process, methanol is converted to formaldehyde via partial oxidation on a heterogeneous iron-molybdate catalyst. To an extent, the formed formaldehyde (FA) is over-oxidized into carbon monoxide (CO) which cannot be recycled into FA. As CO affects the environment negatively and decreases the process economy, internal attempts have previously been made to decrease the CO formation of t

The Cerithium limestone Member (Mb) at Stevns Klint holds an invaluable record in understanding the marine recovery after the K/Pg mass extinction. The Cerithium limestone Mb constitutes a pale yellow limestone including several different microfacies and a large boxwork of Thalassinoides burrows and flint nodules. This paper aims to describe these microfacies in detail and document their vertical

This study aims to analyze the effects of the share of female politicians in parliaments on economic growth. The study examines 180 countries over ten five-years periods between 1972- 2022. Economic growth is used as the dependent variable and is calculated as a five-year GDP per capita growth rate. Additional variables were included in the analysis to control the relationships and avoid omitted v

Research has long been interested in technological development and its effect on human outcomes, but we know little about how automation risk affects occupational and educational choices. I used a pre-registered online experiment with an information treatment containing the automation risk for teachers, economists, office clerks, and registered nurses to investigate how automation risk affects att
