Three different classification solutions for distinguishing events from non-events in surveillance audio are described and evaluated. The three compared methods are energy functions, Gaussian mixture modelling algorithms (GMM) and existing voice activity detectors (VAD). Recorded test signals with corresponding manually labelled ground truth files are used to determine the accuracies of the method
In the realm of urban planning, urban greening – the creation or restoration of green spaces in cities – has risen as an attractive approach for policy-makers and planners engaged in sustainability. As the benefits of urban greening are many, from social and cultural to environmental and economic, it has become positioned as a win-win solution to several urban challenges related to sustainable dev
In today’s world, many companies are pushed to adapt their business models in response to evolving external pressures. While business model change has received increasing attention in research, relatively little is known about how such change actually unfolds inside organizations. Responding to calls for a more dynamic view of business models, this thesis explores how strategy process factors medi
Humanitarian aid workers (HAWs) face increasing risks in conflict zones, with 2024 marking the deadliest year on record. International humanitarian organisations (IHOs) must address this trend to continue delivering aid and protecting HAWs. This study investigates how IHOs adapt to the evolving risks in these contexts and explores challenges that adaptation measures may entail. A qualitative resea
Denna uppsats undersöker hur systemet för ersättning av rättegångskostnader i förvaltningsprocessen förhåller sig till rätten till en rättvis rättegång. Denna uppsats undersöker också vilka möjligheter som finns för att få ersättning för rättegångskostnader i förvaltningsprocessen genom en separat skadeståndsta-lan i allmän domstol. För att svara på frågeställningarna tillämpas rättsdogmatisk metoThis thesis examines the system for reimbursing legal costs in the administra-tive law proceedings and how it relates to the right to a fair trial. It also inves-tigates the possibilities for obtaining reimbursement of legal costs in adminis-trative proceedings through a separate damages claim in a general court. To address the research questions, a legal dogmatic method is applied, with a signif
The rising levels of greenhouse gas emissions, especially of carbon dioxide, imposes a significant threat to the world, requiring new decarbonisation technologies. This thesis explores integrating a Power to X system with an existing biogas plant utilizing waste from salmon fishery. Three pathways for upgrading biogas to methanol or methane were investigated: (P1) direct carbon dioxide to methanol
This study investigates consumer-perceived frictions in cross-channel return processes within Nordic omnichannel retailing and examines how these frictions reflect underlying reverse logistics (RL) integration gaps. While omnichannel research has extensively addressed seamless front-end experiences, the post-purchase return phase remains under-theorized and is often treated as a “black box”, disco
Detta examensarbete undersöker övergången från en monolitisk skrivbordsapplikation till en distribuerad webbaserad klient inom ett industriellt mjukvarusystem som utvecklats i samarbete med Energy Opticon. Examensarbetet fokuserar på implementering och jämförelse av modulen Smart Data View (SDV) i två olika klientarkitekturer: en befintlig skrivbordsapplikation byggd i VB.NET med Windows Forms ochThis thesis explores the transition from a monolithic desktop application to a distributed web-based client within an industrial software system developed in collaboration with Energy Opticon. The thesis focuses on the implementation and comparison of the Smart Data View (SDV) module in two different client architectures: an existing desktop application built in VB.NET using Windows Forms and DevE
Köp av bostäder skiljer sig från många andra avtal som träffas av en privatperson under dennes liv och för många enskilda är köp och försäljning av privatbostad av stor ekonomisk betydelse. Uppsatsens syfte är att utröna några av de civilrättsliga konsekvenser som falsk budgivning kan få på ett köpeavtal om fast egendom. Köp av fast egendom regleras i jordabalkens fjärde kapitel och skiljer sig The purchase of housing differs from many other agreements which an individual is confronted by during her life, and for many individuals, the purchase and sale of private housing are of major economic significance. The purpose of this paper is to determine some of the civil law consequences false bidding may have on a real estate purchase agreement. Purchase of real estate is regulated in the 4t
The aim of this study is to analyze how relevant education members of the Swedish parliaments have in relation to the committee they are on. We want to investigate the degree to which they are governed by expertise. The Swedish parliament consists of 349 members, but since this study only focuses on the committees, the number reviewed are 254 members. In order to implement this study, we have used
There is only one large ocean that makes up our blue marble, even though we’ve given it many different names. It’s difficult to see where one ends and another begins and change in one place has an effect elsewhere. The ocean connects us all and we are depended on its grace to provide us with life. The beach opens our way to the world and closes us off. It is a conflict zone in times of climate cha
This thesis measures cost efficiency in the production of health care and social services in Sweden. The object of analysis is not provider efficiency, but instead the relative efficiency of political organizations or different contractual arrangements. The thesis focuses on: 1) the measurement of cost efficiency, 2) the investigation of potential trade-offs between quantity of health care service
Hexokinase 2 (Hxk2p) from Saccharomyces cerevisiae is a bi-functional enzyme being both a catalyst and an important regulator in the glucose repression signal. In the presence of xylose Hxk2p is irreversibly inactivated through an autophosphorylation mechanism, affecting all functions. Consequently, the regulation of genes involved in sugar transport and fermentative metabolism is impaired. The ai
Vätgas har potential i ett energilagringssystem eftersom det är en energibärare som är väldigt energirik och kan lagras i stor skala. Vätgas kan produceras enkelt via elektrolys av vatten och lagras i stora mängd under högt tryck, vid behov kan vätgasen sedan brännas i en kraftverksprocess och generera elektricitet. Då förbränning av vätgas med syrgas enbart bildar vattenånga kan ett förnybart eneHydrogen gas has potential to function as an energy storage solution due to its high energy content and its suitability for large scale storage. Hydrogen can be produced by water electrolysis and can be stored in large scale under high pressure, when needed the hydrogen can be burned in a thermal power plant to generate electricity. Since combustion of hydrogen with pure oxygen only yields steam,
Thesis purpose: The combined research on the effects of logo redesign on heritage brands is underdeveloped. Therefore, we contribute with insights to this nascent subject and provide inspiration for others to continue. Methodology: This thesis uses quantitative methods with a mixed experimental design to test the impact of different logo versions on Brand Attitudes and Perceived Brand Authenticity
Background. Sporadic cases of abdominal pain and dysmotility has been described after treatment with gonadotropin-releasing hormone (GnRH) analogs. The aim of the present study was to scrutinize for patients with severe gastrointestinal complaints after treatment with GnRH analogs, to describe the expression of antibodies against progonadoliberin-2, GnRH1, GnRH receptor (GnRHR), luteinizing hormon
Background: Proteolytic Clostridium botulinum is the causative agent of botulism, a severe neuroparalytic illness. Given the severity of botulism, surprisingly little is known of the population structure, biology, phylogeny or evolution of C. botulinum. The recent determination of the genome sequence of C. botulinum has allowed comparative genomic indexing using a DNA microarray. Results: Whole ge
Direct electron transfer reactions of Bacillus halodurans bacterial multicopper oxidase on bare spectrographic graphite, as well as bare and thiol-modified gold electrodes were studied using cyclic voltammetry, potentiometry, amperometry, and spectroelectrochemistry. The redox potential of the T1 site of the enzyme was measured using mediatorless redox titration and found to be 325 mV +/- 10 mV vs
