The Narrative Clip is a small wearable camera that takes an image every 30 seconds. By wearing the clip a whole day a user captures a long image sequence of the day's events. In this thesis we will segment such a sequence into the individual events automatically. Multiple sequences are segmented by humans in order to nd a groundtruth for each sequence. The groundtruth will be used to determine
Övergödning är ett pågående problem i Östersjön och tas upp i bland annat the Baltic Sea Action Plan och inom ramen för Sveriges miljömål. Övergödningen beror på tillförsel av näringsämnen som kväve och fosfor, vilka når havet från flera olika källor. Dels från punktkällor som industriutsläpp och dels från mer diffusa källor som förbränning av fossila bränslen, skogsbruk och jordbruk. Från jordbruEutrophication is an ongoing problem in the Baltic Sea and is therefore found as a topic of the Baltic Sea Action Plan as well as the environmental goals of Sweden. One source to eutrophication is the leakage of phosphorus from agricultural lands. This study was aimed to map risk areas of phosphorus leakage from surface runoff in a catchment located in the southern parts of Sege river, Scania. The
It has been argued that cognitive biases are the source of a range of problems in modern society, from stereotype formation to belief in pseudoscience. One of those biases causes people to perceive causal relationships between unrelated events and is known as illusion of causality. Scientists are pointing to the importance of strategies to debias people on a global scale. However, research on effe
The paper investigates data on purchasing price of wheat from Swedish grain buyer Lantmännen and MATIF future contracts on milling wheat in an attempt to replicate the conditions for a Swedish farmer trying to manage his risk on wheat by trading future contracts on the MATIF exchange. Two static linear regressions and four dynamic GARCH models are employed on a sample of 1679 daily returns and 339
Den här studien har skapats för att effektivisera analysen av tabletter innehållande den aktiva substansen nikotin på Kenvue. Nuvarande teknik för att analysera nikotinhalten i 2 och 4 mg tabletter är vätskekromatografi (UHPLC), en tidskrävande teknik som kräver provupparbetning. Near infrared (NIR) spektroskopi är en snabb analysteknik som är icke-destruktiv och kräver ingen provupparbetning vilkA study has been created to develop a method quantifying the active pharmaceutical ingredient (API) nicotine in tablets with near infrared (NIR) spectroscopy using chemometrics. The current technique, liquid chromatography (UHPLC), used to determine the nicotine content in tablets is time consuming and require sample preparation. NIR spectroscopy is non-destructive and the implementation of NIR sp
Electrocardiogram (ECG) is an important tool for diagnosing myocardial infarction (MI), but analyzing the ECG signals can sometimes be difficult for physicians. Machine learning could potentially help provide a fast and consistent interpretation of ECG signals. This study aims to evaluate the performance of different machine learning models for classifying MI using ECG data from the PTB-XL dataset
I denna avhandling undersöker vi möjligheten att använda Siamesiska Neurala Nätverk för att detektera röstförändringar bland patienter som lider av återkommande stämbandscancer. I samarbete med VoiceDiagnostic Sweden AB och läkare vid Lunds Universitetssjukhus konstruerades modeller för att mäta avstånd mellan olika röstinspelningar, samt avstånd mellan mindre segment av röstinspelningar. De resulIn this thesis, we investigate the possibility of using Siamese Neural Networks to detect voice changes in the voices of patients su↵ering from a recurrence of their vocal cord cancer. In collaboration with VoiceDiagnostic Sweden AB and physicians at Lunds’s University Hospital, models were trained on audio features in order to learn distance measures between recordings, and segments of recordings
Dagens smartphones – inte så klimatsmarta I dagens slit-och-släng-samhälle köper folk de senaste modellerna bara för att vara trendiga, men lämnar sin gamla telefon i byrålådan. Vid tillverkning av mobiltelefoner krävs även många olika material och utvinning av dem bidrar till stor miljöpåverkan. Återvinningsföretaget Sysav står nu i ett vägskäl mellan hur de ska välja tjänstetelefoner till företThe cell phone industry is one of the most linear sectors, which means high resource consumption in the production of telephones and difficulties in repair. In addition, only 10-12% take-back of used units takes place, the rest are often forgotten in drawers or handled incorrectly. An interesting area of research is how companies can make their choices to reduce the life cycle environmental impact
Introduction Common complications after surgical procedures include surgical site infection, wound rupture and incisional hernia. Wound healing can be influenced by the technique for abdominal access and closure. A Suture-Length to Wound-Length (SL/WLr) ratio ≥ 4 is advised to achieve a high-quality wound closure. This thesis describes the background and clinical realities of abdominal wall relate
As a complementary product to the Tetra Brik Aseptic packaging system, Tetra Pak is about to introduce a new, value added, aseptic packaging system called SCAP. The SCAP packages consists of a lower part made of carton and an upper part made of plastic, similar to a PET-bottle, resulting in a bottle shaped package. The purpose of this thesis is to design a logistical- and material-handling system
Forecasting stock market returns is an interesting topic since more and more Swedes enter and invest in this market. Theory implies, however, that such exercises should be impossible. The aim of this thesis is to investigate the possibility to forecast future stock returns by looking at macroeconomic variables’ history. The study is limited to the Swedish market as it is based on the OMXS30-index
This paper examines embodiments of motherhood on Instagram among influencers. The study analyzes what types of embodiments occur through affect theory, framing theory and performativity. The data that has been analyzed consists of Instagram posts from 10 Swedish influencers who post about motherhood. The analysis reveals often use of strong affects, which are often performed specifically with and
Populärvetenskaplig sammanfattning: Huvudsyftet med detta examensarbete har varit att dokumentera samt jämföra skånska sandstenar med västgötska sandstenar avsatta under kambrium (ca 570 - 500 miljoner år). De skånska lagren utgörs till stor del av 120 meter sandsten och de västgötska av ca 35 meter. Sandstenen består huvudsakligen av kvartskorn och kallas därför kvartsitisk sandsten. Under kambThe Lower Cambrian strata of the Caledonian foreland of southern Sweden consist mainly of quartzitic sandstones with thicknesses of approximately 35 meters in Västergötland and 120 meters in Skåne. In the distal, moderately buried western members of the File Haidar Formation of Västergötand porosity and permeability was higher than in the proximal deeply buried units of the Hardeberga Formation of
The child soldier issue is complex in many different ways. Taking into account the different ideas of childhood, the concept of human rights in general and child rights in specific the question about the child soldier and its rights appears to be far from easy to understand. In this thesis I will try to illustrate the complexity by comparing relevant international law applicable to the child sold
Abstract In this study I have sought to understand the conditions for knowledge and objectivity in family assessment-work. I have used a philosophical theory to reach understanding of what possibilities and obstacles there are for an assessor in trying to reach knowledge about, and to be objective in, working with child and family-assessment. To fulfill my purpose I have made one group- and one s
