The purpose of the thesis is to investigate abandoned carts amongst logged in customers with at least one product added in to their cart and at least one visit to the payment page. Since the response variable "cart" is binary and we are studying the probability of a cart being abandoned, the suitable me
This master thesis presents a suggested Renovation Passport for two typical 1960s single-family houses. Following the recently approved Energy Performance of Buildings Directive (EU 2024/1275A), all member states are to implement voluntary Renovation Passports by 2026, which will aid in reaching the 2050 goal of a decarbonized building stock. The aim of Renovation Passports is to provide long-ter
With the rapid growth of AI and large language models, concerns about their energy consumption have become increasingly prominent. The traditional digital von Neumann architecture is ill-suited for deep neural networks, prompting the exploration of neuromorphic computational models. These models draw inspiration from nature and the brain to integrate memory and computation efficiently. This thesis
Payments for ecosystem services (PES), a mechanism of incentives or compensation to landowners for provision of ecosystem services, have grown as a tool for meeting conservation goals. The Costa Rican payments for ecosystem services (PSA) program is one of the best-known examples because of being one of the most established. Despite this, the PSA program and many other PES programs do not monitor
Detta examensarbete undersöker hur ett business-to-business (B2B) inriktat företag som utvecklar ett direct-to-consumer (D2C) segment bör anpassa sin marknadsföringsstrategi för att växa genom marknadspenetration. Författarna har undersökt ett svensk kreditupplysningsföretag, Upplysningscentralen (UC), som har expanderat sin verksamhet till konsumentmarknaderna för kreditinformationstjänster och iThis thesis explores how a business-to-business (B2B) focused company should adapt the marketing strategy when transitioning into the direct-to-consumer (D2C) market, in order to grow through market penetration. The authors have examined a Swedish credit reference agency, Upplysningscentralen (UC), having expanded into the consumer markets of credit information and identity protection services – t
The fastest rising group of entrepreneurs is represented by females, yet entrepreneurship is still considered a male-dominated industry. Female entrepreneurs have to deal with gender-stereotypical challenges, due to the overrepresentation of men in entrepreneurship. Contemporarily, the concept of female entrepreneurship is understudied and scarce, specifically the entrepreneurial identity. This t
A vast majority of rural dwellings in Ukraine are inefficient from an energy perspective, with a major need for energy-efficient renovations. A lot of these buildings are also having problems with the indoor climate, with poor ventilation combined with indoor combustion of fuel which can cause negative health effects. A large part of Ukrainian households is also suffering from energy poverty which
The European spruce bark beetle is an insect that is often referred to as a pest. Responsible for the destruction of over 150 million m3 of Norwegian spruce forest in Europe over the last 50 years makes this insect one of the major disturbances to the forest industry. With global warming at large, changes of the distribution of the bark beetle have emerged with large outbreaks now regularly occurr
Wetlands are valuable ecosystems, and assets for human life, that must be regularly monitored, starting with accurately mapping their location and extent. However, an updated national inventory of wetlands is needed. The availability of multi-source data, and advanced machine learning algorithms in Google Earth Engine (GEE) offers excellent opportunities to map wetlands on a country-wide scale. Th
At the IT department of IKEA, test specialists who are responsible for software testing are currently using a suite from Hewlett Packard called HP Application Lifecycle Management that includes an analysis tool for test result evaluation. During the implementation of this thesis work, the real world demand for a replacement of the analysis tool became apparent, as the interface of the analysis too
Detta examensarbetet handlar om att forma en hemisfäroid från en platt honeycomb-skiva samtidigt som honeycomb-strukturen bibehålls. Honeycomb-strukturen är ett hexagonalt mönster som kan vara gjord av hexagoner, cirklar eller trianglar. Inom kartografi görs jordens sfäriska yta om till en platt representation i form av en karta. Omvandlingen är omöjlig utan förvrängning eller uppdelning i mindreThis Master thesis is about forming a hemispheroid out of a flat honeycomb while retaining the honeycomb structure through an even spread of deformation. The honeycomb structure is a hexagonal structure which can be made out of hexagons, circles or triangles. In cartography the surface of the earth, a spheroid, must be distorted or cut up in order to create a flat map. In the same way forming of
Over the past two decades many discoveries of exoplanets have been made, which have drawn much attention to extrasolar planetary systems. In this work we study the composition of these systems and search for analogues of the Solar System. We considered the planets in the database at exoplanet.eu. The search of solar-like systems required these planets to be classified. The classification was perf
Clarifying the mechanisms maintaining atrial activity during atrial fibrillation (AF), still remains as a relevant topic. The purpose of this master thesis is to apply correlation analysis and system identification methods to study spatial and temporal propagation of atrial activation along coronary sinus (situated in the posterior left part of the heart, in the groove between left atrium and left
This thesis derives a consistent adjoint sensitivity analysis for an adaptive time- stepping scheme, the Singly Diagonally Implicit Runge-Kutta scheme and evaluates its performance by comparing the scheme with a conventional time integration ap- proach. The goals are to derive the sensitivity analysis and assess whether solution accuracy can be improved while preserving computational efficiency. B
Allvarlig brottslighet som begås inom kriminella nätverk har ökat drastiskt under senare år. Skjutningar och sprängningar har blivit alltmer förekommande och nu diskuteras även finansierandet av skjutvåldet genom narkotika-, smugglings- och ekonomisk brottslighet i politiska debatter. Hur man ska komma till rätta med problemet, med hänsyn till förbättrade tekniska förutsättningar och tystnadskultuSerious crimes committed within criminal networks have increased drastically in recent years. Shootings and explosions are unusually often occurring in Sweden and now the financing of this deadly violence by drug, smuggling and financial crimes is also discussed in political debates. How to effectively deal with the problem, despite improved technology and a culture of silence in criminal gangs, i
Surrogatmoderskap innebär att en kvinna blir gravid med den uttalade avsikten att efter födseln inte behålla barnet utan överlämna det till ett par eller annan person. Förfarandet används i främre utsträckning idag för att ofrivilligt barnlösa ska få barn. I denna uppsats undersöks surrogatmoderskap, men även assisterad be-fruktning, samt hur föräldraskap definieras eftersom det ofta uppstår probSurrogacy means that a woman becomes pregnant with the express intention of not keeping the child after birth but handing it over to a couple or another person. The procedure is used to a greater extent today to enable involuntarily childless people to have children. This essay examines surrogacy, but also assisted fertilization, and how parenthood is defined, since problems often arise with paren
Genom bestämmelserna om processuell edition i 38 kap. rättegångsbalken kan en part i ett tvistemål få tillgång till en handling av bevisbetydelse som innehas av motparten eller tredje man. Denna så kallade editionsplikt uppställer flera bifallsförutsättningar. Editionsyrkandet måste ta sikte på en handling som är identifierad, innehas, kan antas vara av betydelse som bevis och som är rättsligt relThe provisions of Chapter 38 of the Swedish Code of Judicial Procedure enable the parties in a civil litigation to gain access to a document held by the counterparty or a third party. The obligation to produce a document requires that the document is identified, in the possession of the respondent, of judicial significance and that it can be assumed to be of importance as evidence. In addition, so
I takt med att världen utvecklas med nya tekniska framsteg ökar mängden konsumtion och därmed fortsätter även mängden farligt avfall drastiskt att öka, vilket skapar nya utmaningar för miljön. Vår framtid är helt beroende av om vi väljer att hantera detta komplexa avfall på ett hållbart sätt, eller väljer att försumma vårt ansvar. Trots de betydande framstegen som gjorts till följd av implementeriWith a rapid increase in technological achievements and consequently consumption, the amount of toxic waste continues to expand drastically, creating new environmental challenges. Our future depends on if we manage this com- plex waste in a sustainable way or choose to neglect the issue. Despite the significant progress made from implementing the Basel Convention in 1992, troubling questions regar
Air Traffic Controllers (ATCOs) are essential sharp-end workers in the increasingly complex Air Traffic Management (ATM) system that the European ATM network has become. This research is based on an event that occurs many times daily in the Copenhagen Area Control Center (ACC). ATCOs choose whether or not to split sectors. To cope with workload, which is constituted by variation in traffic volume
