The objective of this thesis was to investigate how double skin facades (DSFs) meet daylight and energy requirements compared to single skin facades (SSFs), also considering the life cycle costing (LLC) of both solutions. A South facing, an unobstructed glazed office building in Sweden was used as a basic building object, where SSFs and DSFs were iteratively applied. A mid-level floor was chosen a

Digital media and social media are by now established platforms for daily online social interaction, expression and debate, also in the political field. They offer users a space to voice and exchange opinions, as well as a tool to organise political acts of protest or support around offline world events. And they are changing the game of politics in remarkable ways. Political institutions such as

In many cities around the world, the financial crisis 2007 served as an opportunity both for grassroots movements and governments to rethink existing models of urban development. Some authors have pointed out that the crisis served to elevate discourses for progressive post-neoliberal urban transformations. Other, more sceptical accounts have pointed at the shift towards participative, networked g

Smart komprimeringsteknik för ljudinspelningar Omfattande forskning inom videokomprimering har lett till en märklig balans där ljudspåret ibland tar större plats än videospåret i övervakningsinspelningar. För att jämna ut detta behövs smarta tekniker även för ljudkomprimering. Det här arbetet presenterar ett förslag för att minska ljuddatan med mer än 50 %. Det är vanligt att majoriteten av mateThree 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 this thesis we propose a new form of Variational Autoencoder called the Conditional Latent Space Variational Autoencoder or CL-VAE. By conditioning on a known label in a dataset we can decide what points are being mapped to what prior distribution. This makes the latent space more understandable and separates the classes further. It also subverts the tug-of-war effect between reconstruction los

Polylaktid (PLA)- en plast som har dålig nedbrytningsförmåga och borde kallas något annat Plasten polylaktid, PLA, marknadsförs som bionedbrytbart, någonting som faktiskt inte verkar stämma enligt olika studier. Plasten bryts inte alls ner under samtliga förhållanden i naturen utan kräver speciella anläggningar för fullständig nedbrytning. Inte heller tycks PLA uppfylla den europeiska standarden fThis paper aims to look at the positive and negative aspects of the biodegradable material poly(lactic) acid (PLA) compared to controversial plastics. This is done through a literature study. PLA is a biobased and biodegradable plastic that are used in for example medicine and packaging materials around the world. The results from this study show that the biodegradation of the material is not that

Balanseringsprincipen är en metod av ekologisk kompensation som används i Helsingborg och går ut på att kompensera förlorade naturvärden (t.ex. träd, buskar) och sociala värden (t.ex. lekplats, sport) vid stadsutbyggnad. Den här studiens resultat tyder på att metoden som tillämpas idag är otillräcklig och pekar på ett flertal förbättringsområden. Framför allt krävs det ett tydligt mål med metoden In the context of continuous biodiversity loss connected to land-use changes and urban development, different methods such as biodiversity offsetting with the underlying aim of achieving “No Net Loss” (NNL) of biodiversity has been proposed. Compensation according to the mitigation hierarchy is one type of biodiversity offsetting which currently is being used in the municipality of Helsingborg, Sw

Detta examensarbete ämnar att undersöka om och hur man skulle bygga en modell för att kunna beräkna utsläppen av växthusgaser vid förändringar av transmissionskapacitet. Arbetet avhandlar hur det nuvarande elsystemet är uppbyggt och påverkan på utsläppen av växthusgaser ifrån ökad produktion av förnyelsebar elproduktion och ökad transmission av elektricitet. Utifrån att studera vind- och lastdataIn the light of the importance of climate change and the emissions that have induced it, the ability to calculate the effect on emissions by changing transmission capacity is vital. A model to perform such indicative calculations is developed in this thesis. After researching how the current electricity system is organised, the effects on GHG emissions that are expected from increased renewable el

Årligen i Sverige, förlorar stora mängder material stora delar av sitt ekonomiska värde på grund av ineffektiv materialåtervinning. I den vanliga linjära ekonomin är materialåtervinning inte prioriterat medan i den cirkulära ekonomin är återvinning en viktig del. PolyPlank har med sitt eget polyplankmaterial byggt upp sin verksamhet baserat på den cirkulära ekonomins principer. PolyplankmaterialetYearly in Sweden, large quantities of material lose much of their monetary value due to poor material recycling efficiency. In the common linear economy, material recycling is not prioritized, however within a circular economy recycling is a vital part. PolyPlank has with their own polyplank material built their company based on the principles of the circular economy. Their polyplank material is a

The aim of this study is to understand how the emotional aspect of employee identification evolves through daily interaction in multicultural organizations. Applying a process model of individual identification, this research aims to offer an employee perspective, to uncover the communication challenges employees face and how they make sense of the interaction at work relating to the feeling of be

Bakterier är något som finns överallt. En del goda, som gynnar vår tarmflora, medan en del är onda och kan ge oss infektioner och matförgiftningar vid fel hantering. Just för RTE-sallader (ready-to-eat) är det extra viktigt att rutiner följs eftersom de inte värmebehandlas. Faktorerna som påverkar bakteriernas tillväxt är tillgång till näring, vatten, pH, temperatur, salt, socker och syre. Detta a

The determination of the built-up area of a refugee camp is an important task as it can be used for estimating the population. While high resolution satellite imagery can be costly, since 2015 Sentinel-2 data has become available through the European Space Agency. Sentinel-2 offers 10 m resolution images with frequents updates. In this paper three methodologies are compared for the purpose of esti

Sustained economic growth is essential for developing countries in order to develop. Resource dependent countries face difficulties creating sustained growth as most suffer from a resource curse. Building on previous literature, this research aims at exploring the resource curse literature, with a focus on the time period 1995-2016, which includes the commodity boom, for countries located in Sub-S

The purpose of this paper is to examine if it is possible to profitably implement a market neutral trading strategy, so-called "pairs trading", on three different Swedish investment companies. It can be concluded that applying a pairs trading strategy on [these three] Swedish investment companies and their underlying listed assets has the potential to beat the market Sharpe ratio. Howeve

Tid och pengar är två viktiga faktorer i dagens samhälle. Därför är det intressant att utvärdera om gratisprogram motsvarar den funktionalitet och de behov som kommersiella programvaror erbjuder i avseende på publicering av webbkartor. Väldigt många människor använder dagligen tjänster som Google Maps, Eniro och hitta.se för att skriva ut en karta, få en vägbeskrivning, visa busshållplatser, restIn most projects, there is a need to visualize geographic data in a map and in most cases, this is done in an interactive map on a computer, tablet or mobile phone. To be able to publish geographic data on the web, several components are needed. These components are in many cases purchased with a user license from a company that provides the customer with support and other user instructions. An al

Almost half the Danish population report that they have undertaken action(s) with the main purpose to lower their personal greenhouse gas emissions within the last three years. It has become “in” to be green, yet certain practices are perceived as “better” than others although they do not necessarily result in a lowered environmental impact. Why is that? Data from seven semi-structured interviews

In the last two decades, dominant business models in the economy have turned to aggregating the resources of people to provide services to consumers through a platform. Airbnb, Uber, and Amazon are a few examples in sharing economy services (SES) business employing this model. Blockchain is set to disrupt these giants by facilitating direct access between users and service providers in a secure an

Façade fires are a big concern due to past incidents and the large number of victims encountered. Vertical flame spread mechanism specific to this type of fires is a complex phenomenon with parameters that are often difficult to be coupled. Moreover, the architectural design of the façade assemblies further complicates the evaluation of the fire safety strategies. The energy reduction requirement

Krita-paleogen-gränsen har länge varit central i diskussioner mellan forskare runt om i världen, då den markerar/sammanfaller med utdöendet av 75% av jordens arter till följd av ett enormt asteriodnedslag på Chicxulúbhalvön i Mexiko. Gränsintervallet är vida utbrett i sedimentära lagerföljder som bildades under denna tid, och kan identifieras genom sina unika kemiska egenskaper och karakteristiskaThe Cretaceous-Paleogene boundary has long been a center of discussion amongst scientists as it marks the extinction of 75% of all species on Earth. This mass extinction event was probably caused by an enormous asteroid impact event in what is now Mexico. The boundary interval is easily identified in the sedimentary geological record because of its unique chemical properties as well as its charact

Salafism is a fundamentalist belief of Islam and its believers strive to live like their forefathers did. In Sweden, the group aim for peaceful segregation and isolation among their believers, rejects modernity and avoid socialisation with Western society and its inhabitants. Salafism has recently acquired more attention due to the terrorist organisation ISIS which justifies their actions based on
