Denna kandidatuppsats, Att springa på likes, undersöker hur träningsappen Strava använder spelifiering och övertygande systemdesign. Analysen utgår från ramverket Persuasive Systems Design (PSD) för att förstå hur appen påverkar användares träningsmotivation. Syftet är att identifiera vilka spelelement i Strava som upplevs som mest motiverande samt om dessa designprinciper stödjer långsiktiga trän
The growing emphasis on sustainable packaging and increasing regulatory pressures on recyclability have driven the need for alternative barrier materials in multilayer beverage cartons. This study investigates the recycling behavior of a water-soluble polymer, polyvinyl alcohol (PVOH), used as a barrier layer in beverage cartons. A lab-scale experimental setup was designed to simulate industrial r
Detta arbete är en explorativ studie om svenska fysiklärare på gymnasiet och hur de ser på språkets roll inom fysikämnet samt hur de ställer sig som lärare i rollen att behöva vara en lärare som undervisar språkliga element. Studien genomfördes med hjälp av kvalitativa intervjuer där totalt fyra lärare med varierande erfarenhet som fysiklärare intervjuades. Resultaten analyserades med hjälp av ett
This study focuses on the feasibility of gravity-driven membrane (GDM) microfiltration (MF) as a low-energy treatment option for urban lake restoration in Lund, Sweden. Four lakes, namely Sjön Sjön, Stadsparken, Kunskapsparken Dammen, and Spexardammen, were selected based on their varying water quality characteristics. A silicon carbide (SiC) membrane was tested in a laboratory-scale setup operate
This study addresses the thermal comfort challenges faced by high-altitude residential buildings in Nepal. A field study was conducted in five houses located in the city of Marpha, where observations concerning building materials and construction types were made alongside measurements of air leakage, indoor temperature, relative humidity, and CO2 concentrations. Aimed at raising indoor temperature
This thesis explores how the relationship between economic shocks and fertility rates has evolved in Spain from 1977 to 2024, using regional panel data across the country’s 17 autonomous communities. The analysis applies two-way fixed effects models to assess whether the impact of economic variables, particularly unemployment, has diminished over time, as demographic and cultural factors have gain
This thesis investigates how sampling strategies influence the predictive accuracy and interpretability of bankruptcy models. Using financial data from U.S. publicly listed firms (2009 to 2023), it compares logistic regression and random forest classifiers trained under three sampling setups: no resampling, random undersampling (RUS), and SMOTE. Models are trained to predict one-year-ahead bankrup
Då andelen äldre ökar globalt kommer allt fler personer vara i behov av medicinteknisk utrustning, såsom hygienstolar, för att genomföra olika basala hygienrelaterade aktiviteter. Kommodpannor är vanliga tillbehörsprodukter till hygienstolar som traditionellt har fästs under hygienstolens sitts med hjälp av skenor, en fästmetod som medför hygienproblem samt en klämrisk för vårdtagaren.This thesis project was completed in collaboration with Arjo, a MedTech company headquartered in Malmö, Sweden. Arjo’s product offering is largely centered around providing healthier outcomes for individuals with limited mobility and includes products for patient transfer, hygiene, disinfection, etc. One product type which is central to Arjo’s mission is the hygiene chair. This type of product is
Introduction: Side-stream residue, oat okara, from the oat-milk production contains valuable nutrients but possesses a high risk of microbial spoilage. Valorisation of oat okara is therefore important to make sure that the oat beverage production stays sustainable. In this project, High-pressure processing (HPP), heat treatment and Lactobacillus fermentation have been evaluated for their microbial
Distributed control systems, förkortat DCS, är ett komplett automationssystem som har stora användningsområde inom dagens processindustri. På grund av sin skalbarhet, driftsäkerhet och redundansmöjligheter är dessa system idag vanligt förekommande. DCS är oftast väldigt stora och komplex system som kräver mycket tid och arbete för att starta igång. Detta resulterar i att uppstartstiden för projekt
This thesis explores the configurability of IPs for ASICs by looking into the design of SPI_S, an IP used for communication between ASICs and peripheral devices. Configurability is explored to reduce manual labor when requirements set on the IP change between projects. The thesis looks into the challenges of developing a configurable IP, including architecture, design, and verification. In additio
The purpose of this thesis is to apply Value Network Theory (VNT) to the understanding of customer integration and co-creation in Public Transport Authorities (PTAs). It aims to identify key challenges and opportunities in this shift, and to provide deeper insights into how PTAs, such as Skånetrafiken and SL, can strategically transition from a traditional value chain model to a more customer-incl
This thesis investigates how young women navigate flexibilization and informalization in the Taiwanese labor market, their motivations guiding the transition from formal to informal sector, and generational differences in terms of motivations and interpretation of informality. A qualitative approach was adopted, entailing thematic analysis based on a corpus of different data, including participant
This thesis investigates gender image in Sichuan based TV dramas supplemented with interviews with women from the region. This research focuses on the region of cultural Sichuan including Chongqing municipality and its perceived differing regional gender hierarchy. It utilizes Feminist Critical Discourse Analysis and Visual Analysis to examine the representation of Gender in two television dramas,
Snabbare kraftöverföring i elbilar med ny teknik Genom att förbättra en central komponent i BorgWarners drivsystem för elbilar kan bilen reagera snabbare, bli effektivare och billigare – utan att öka storlek eller vikt. Många moderna elbilar använder sig av en så kallad Torque Vectoring-teknik för att fördela kraft mellan hjulen och anpassa körningen efter vägförhållanden och körstil. Denna tekniThis master’s thesis investigates the feasibility of alternative actuation methods for the BorgWarner electric Torque Vectoring with Disconnect (eTVD) system. Currently employed in several car models, the existing eTVD system performs admirably. However, BorgWarner’s commitment to technological improvement and the desire to attract potential customers to this unique technique serve as the impetus
