Artificial neural networks are prone to overfitting – the process of learning details specific to a particular training data set. Success in preventing overfitting through combining the L2 and dropout regularisation techniques has led to the combination’s recent popularity. However, with the introduction of each additional regularisation technique to an artificial neural network, there comes new h

Earning conference calls is an important communication tool for companies to provide relevant information about the latest quarter based on the reported earnings. However, the research on the impact of the earning conference calls has for long been a relatively unexplored subject. This study was born out of the ambition to try and expand the research done on earnings conference calls and the possi
I examine a favourite child's effect on educational attainment and mental and physical health and well-being. In the favourite child effect, based on parental preferences in the sex composition of children using a proxy for parental investment, I can assess how parents distinguish inputs based on the sex of their children. Identification utilising data from three longitudinal studies in the Un
The world's elderly population is growing and the future home care is facing great challenges to cover the need of home care that will be required. Digital technical equipment plays a key role in modern health care and can be important to overcome the challenges in the future home care. A challenge that has been discovered within Helsingborg’s home care is that patients are worried about when
In the early 21st century, deflationary trends applied pressure on margins in a range of different industries and subsequently cost reductions were required. Improving efficiency in the supply chain was identified as one of the key sources of potential cost savings. Subsequently, a trend towards slimmer supply chains with less stockkeeping emerged. However, due to the covid-19 pandemic supply chai
The aim of this study was to investigate how social workers reflect on municipal activation for clients who receive financial assistance, and the boundaries the social workers set in regard to the Swedish Public Employment Service. The aim is also to analyze which activation measures are used in the municipality, why they are used and how the social workers use their discretion in decision-making.
The aim of this study was to examine the significance of psychosocial work and perspective in addiction care within the Swedish healthcare system and what it is that enables or limits healthcare counselors’ psychosocial work in the medical context. The methodology is based on a qualitative approach using eight semi-structured interviews with healthcare counselors working with addiction care in the
The purpose of this study is to provide a more profound knowledge of how routines impact creativity when studying a Symphony Orchestra. This includes the exploration of obstacles hindering individuals to be creative as well as enabling factors that enhance creativity within the context of routines. Following an interpretivist tradition, our qualitative study uses an abductive approach to a single
Studien fokuserade på proteinet “galectin-8N”, vilket är ett lectinprotein av betydelse för vissa kroppsliga funktioner som till exempel inflammation, autofagi och cellmigration. Arbetet omfattade tre delmål: 1. att kristallisera två varianter av mänskligt galectin-8N och öka dess reproducerbarhet; 2. att studera bindningar och interaktioner mellan bindningsställen för humana proteinerna och tre sThis thesis focuses on the protein “galectin-8N” which is a lectin protein that takes part in several physiological functions such as inflammation, autophagy, cell migration, and more. The project has three objectives: to observe and increase the reproducibility of crystallization of two variants (wildtype and mutant) of the human protein galectin-8N and to analyze the binding site when three diff
In life-threatening conditions in the vessels of the brain, neurointervention can be the treatment that saves lives. With only one incision in the vessel of the groin, a catheter can be navigated to the affected vessel and treatment can be performed using tools inserted through the catheter. In this report, a training model for neurointervention consisting of interconnected vascular models has be
Universum tros ha en diameter på kring 93 miljarder ljusår. Det är därför svårt att tänka sig att hela universum en gång i tiden fick plats i en enda punkt för 13,8 miljarder år sedan. Sen kom den stora smällen! Det som följde var troligen en kort period av väldigt snabb expansion. På samma sätt som ett jetplan som accelererar förbi ljudvallen resulterar i en ljudbang, borde den snabba expansionenIn this thesis, the consequences of introducing Yang-Mills fields into cosmology are investigated. This is done by the effective action approach, in which the coupling constant is allowed to depend on the quantum fields. The equation of state and scale factor are then found for the flat universe filled with either chromoelectric or chromomagnetic fields. From this, we draw conclusions about the hi
The common cold may affect an individual's life, or socio-economic development. This study investigated the effect of a probiotic product (mixed strains) on colds and changes in the oral microbiome. The study included 45 subjects, 23 taking the probiotic product (probiotic groups) and 22 taking the placebo (placebo-control group). The number of colds and duration of colds were investigated sep
As climate change adaptation becomes more mainstreamed, there has been an increasing focus on incorporating local knowledge to ensure equitable adaptation pathways. However, adaptation discourses prioritize scientific understandings of climate change, ignoring epistemological differences in knowing climate change. Interventions treat space as inert and fail to consider how spatial relationships co
Konsekvenserna av att missbedöma framtida försäljning kan för en restaurang vara förödande. Optimistiska prognoser kan leda till överbemanning och matsvinn. Å andra sidan kan pessimistiska prognoser leda till att personal måste ringas in i sista stund vilket skapar en dålig arbetsmiljö för de anställda. I en undersökning från Hotell- och Restaurangfacket angav 59 % att de har problem att planera sWithin the restaurant industry it is common practice to plan staffing and purchases of perishable goods based on intuition. Inaccurate predictions of demand and sales lead to poor working environments and food waste, both being significant challenges for the industry. While digitalization and innovation has enabled accurate data driven sales forecasting methods, many players in the restaurant indu
When working with object detection, the quality and quantity of the training data is often a recurrent bottleneck. This thesis proposes a technique of incrementally improving an object detector using synthetically rendered data. The current training data within the field of focus is limited, and creating new data comes with significant integrity and security risks. By creating synthetic images whe
Dynamic Shear Rheometer, DSR, blev central i samband med lanseringen av Superpave-metoden och är ett instrument som kan användas för att bedöma asfaltsegenskaper. Instrumentet kunde i ett tidigt skede av Superpave-metoden inte utföra mätningar vid låga temperaturer och fick för det ändamålet kompletteras med apparaten Bending Beam Rheometer, BBR. För att få en mer heltäckande översikt över bitumenThe Dynamic Shear Rheometer, DSR, became central in connection with the launch of the Superpave methodology and is an instrument that can be used to assess asphalt properties. The instrument could at an early stage of the Superpave methodology not perform measurements at low temperatures and had to be supplemented with the device Bending Beam Rheometer, BBR, for that purpose.
