This thesis examines the possibility of modelling trajectory and estimating distance during a walk using only a smart phone attached to the waist. Due to GPS not functioning indoors, a navigation system without the need of external communication could be the perfect complement for closed spaces. This thesis considers such a system, where the smart phone contains accelerometer and gyroscope sensors

The study was carried out to identify critical factors for processed fruit shelf life in Tetra Recart packages. To investigate the importance of package volume and headspace volume, vitamin C was chosen to be the indicator. Oxygen in headspace, headspace volume, dissolved oxygen in product, oxygen transmission rate (OTR) and the concentration of vitamin C along storage time were measured to unders

When capturing digital video there is always some amount of noise in the resulting signal. This is more pronounced in low-light conditions. In this thesis we have evaluated five algorithms for motion detection and noise reduction. All algorithms produce a filtered image and a motion mask. One of the algorithms is based on block-matching, one on fuzzy logic and one on low-rank matrix completion. Th

Trafficking in human beings is a topic that has received a lot of attention the last ten years. It has been referred to as a modern form of slavery and a crime against humanity. There is a flood of actors working to fight trafficking and save its victims, occupied with different forms of victim assistance. At the same time the EU is augmenting restrictions on visas and asylum legislation, border c

Crowdsourcing is a relatively new technique which aims to make a specific group of people contribute solutions to simple tasks or problems that are published online by some organization. For this they get some reward, which is usually economic in nature. This technique can be embraced by any kind of company, and since it is done online, it can turn out to be a bit problematic, especially when it c

Populärvetenskaplig sammanfattning: I försök att producera kontinuerlig data över förändringar i jordens magnetfält använder man sig ofta av sjösediment. Magnetiska mineral, eroderade från den kringliggande berggrunden, förekommer ofta i sjöar. Koncentration av dem beror på hur rik bergrunden är på den typen av mineral, t.ex. magnetit. När de magnetiska mineralen faller till botten riktar de in siThe pseudo-Thellier technique was applied to recover relative palaeointensity (PT-RPI) estimates from four core sections, each 2 m in length, obtained from Lake Gościąż, Poland. The varve chronology from Lake Gościąż, originally constructed by Tomasz Goslar, was transferred to the sediment sequence. The chronology was extrapolated to cover the upper parts containing a less pronounced varve structu

Detta examensarbete har som mål att förklara de faktorer som inverkar på ett stenmaterials hållfasthet samt hur Sydsten AB ska kunna bedöma hållfastheten utifrån tillgängliga metoder. Vid Hardeberga öster Lund finns ett stenbrott där Sydsten producerar ballast av en hård, kambrisk sandsten, den s.k. Hardebergasandstenen. Sandstenen är vit eller ljusgrå, ca 535-520 miljoner år gammal och deponeradeThe Lower Cambrian Hardeberga Sandstone Formation of Scania, southern Sweden, consists of a basal arkosic sandstone unit, overlain by three vertically stacked, shallowing-upward sequences. These three sequences consist predominantly of light grey or whitish, quartz-arenitic sandstones deposited in shallow marine environments. The formation reaches a total thickness of about 120 m and is extensivel

The pressure on businesses to “give something back to society” has increased considerably in the last decades and concepts like Corporate Social Responsibility gained enormous populari-ty. While for many years companies have been distributing cash and goods to charity, attach-ing to the CSR agenda a philanthropic nuance, many companies have recently started to shift away from philanthropic giving

Uppsatsen behandlar ansvarsfördelningen mellan åklagare, försvarare och domstol under den svenska straffprocessen, dels under förundersökningen och dels under huvudförhandlingen i första instans. Fokus ligger på ansvar för materiellt riktiga straffdomar och för att oskyldighetspresumtionen upprätthålls i förhållande till misstänkta som erkänner falskt. Syftet med uppsatsen är att utröna dels hurThe essay deals with the responsibilities of prosecutors, defense attorneys and the court during the Swedish criminal process, during the investigation and during the main hearing. The focus is on responsibility for accurate judgments and for maintenance of the presumption of innocence in relation to innocent suspects who pleads guilty. The purpose of the study is to determine how the various par

The objective of the study was to analyse the sediment load into the reservoir Norðursjór, which would form in the case of a dam construction in Vestari kvísl, an upstream part of the river Skaftá, in southern Iceland. The main part of the problem studied was to quantify the sediment transported into the reservoir Norðursjór and to model the bed elevation change of the reservoir as a result of thi

This thesis is about the licensing system of the Creative Commons discussed from the perspective of the theory of the commons mostly as formulated by Elinor Ostrom. The work is started by describing the concepts and theory of common pool resources and regime of the commons for production and distribution of these resources. The main characteristics for successful traditional commons – efficiency,

lnvestigation of weak gravel for road construction has been going on at VTI for many years. The overall aim has been to find test methods that correspond with what happens in the road and that are easy to use in any road laboratory. Following methods have been used in this investigation: planetarytype mixer for wear tests, freeze-thaw variation for weathering tests, Californian Bearing Ratio (CBR)

The purpose of the report is to investigate and evaluate how a global company can use different strategies to achieve competitive advantages for the future. The existing Customer Relation Management (CRM) department in FLSmidth will be investigated to se if possible improvements can be made to make the department become the competitive advantage that it is intended to be. Methodology: To be able t

The goal of this paper is to examine various representations of the third tone in Standard Chinese, both in academic literature and textbooks for beginners, and then evaluate what consequences the choice of representation has for tone instruction. It was found that linguists primarily prefer two models, even though slight deviations were found: either a traditional approach describing the third to

The purpose of this essay is to show how every individual’s consumption affects the environment and people all around the world. Our consumption has another price than the financial one we pay in the store. In my essay I analyze the different aspects of responsibility of states, companies and individuals. To get a theoretical perspective I used Magdalena Bexell’s theories about the need to expand

In the face of extreme and enduring stressors, a self-protection coping mode can be entered to conserve resources (Conservation of Resources (COR) theory principle 4). Self-protection coping is underexplored in COR theory yet may offer insights about how people deal with the significant challenges posed by work today. We investigate this using a large-group collaborative auto-ethnography (CAE) wit

Syndromic testing for lower respiratory tract infections with BioFire® FilmArray® Pneumonia Panel Plus (BF) detects 27 pathogens with a turn-around-time of one hour. We compared the performance of BF with culture. Samples from 298 hospitalized patients with suspected pneumonia routinely sent for culture were also analyzed using BF. Retrospectively, patients were clinically categorized as having "p

Ex-situ Raman spectroscopy is a well-established method for the structural characterization of soot but necessitates a sampling step before analysis is made. This work studied the potential to perform Raman spectroscopic measurements of soot directly in the combustion exhaust gases, i.e., online Raman measurements. Two types of soot were produced from a Mini-CAST soot generator, one immature with
