Personalrörligheten på arbetsmarknaden är viktig såväl i ett långsiktigt perspektiv för landets ekonomiska utveckling och tillväxt som för enskilda arbetstagares upplevelse till handlingsutrymme och hälsa. I denna uppsats diskuteras de tre stora och äldre tjänstepensionsavtalen ITP2, KAP-KL och PA16 Avd2 utifrån vilka konsekvenser dess likheter och skillnader har på arbetstagares möjlighet och vil
Dark Matter is one of the biggest mysteries in physics of our time, with an overwhelming amount of evidence for its existence but lack of direct observation (at time of writing). The focus of this thesis is to reimplement an ATLAS analysis used for Dark Matter searches in the mono-H(bb) channel, and use that analysis in order to study the signal of a new particle called Dark Higgs. The Dark Higgs
This thesis considers bias when studying behaviours in a Cox proportional hazards model. In Cox proportional hazards regressions and cohort studies in general, measurements are often made during a limited period of time. Behaviours may, however, change rather dramatically over time, and if these changes are unknown, they will distort the results in the regression models. We study this problem in t
This project started out as a test, and a request, an invitation to participate in a highly singular architectural project. Located in the western harbour of Malmö, the OHBOY! bike hotel belongs to an ambitious and ground-breaking approach at redefining the way we design cities and map- out our priorities, emphasizing mobility and making an active effort at minimizing our impact on the city’s tra
This thesis empirically quantifies the impact of promotions on store visits in the Swedish grocery retailing sector with nationally representative panel data on household purchases of ground coffee. Using the potential outcomes framework, the impact is calculated as the difference between outcomes with promotion and their counterfactuals estimated with two regression models. The first model is an
No site, no client and no program, instead digitally fabricated physical models were the driver of this project. The method of research-driven design liberated the project from functional and performative demands and opened up for other questions to be raised. The two things that informed the design were the construction process and the material. The material used is clay. With its liquid form, pl
This Master's thesis project aims to explore the possibility of a mixed simulation environment in which parts of a software model for emulating a hardware design may be swapped with their corresponding RTL description. More specifically, this work focuses on the sofware model for Arm's next-generation Mali GPU, which is used to understand system on chip properties, including functionality
The purpose of this master thesis is to investigate the opportunities and challenges of introducing transport plans. By studying some of Sweden’s municipalities' transport plans, the prospect is to identify success factors and critical factors in the process that can be applied in the process of developing transport plans in smaller municipalities – like Vetlanda municipality. The study conduc
Syftet med denna uppsats är att undersöka om utvecklingen av sociala medier som rekryteringskanal kan ha en positiv inverkan på matchningseffektiviteten på arbetsmarknaden. Uppsatsen bearbetar data från SCB och Arbetsförmedlingen och använder Beveridgekurvor tillsammans med matchningsfunktioner för att beskriva matchningseffektivitetens utveckling sedan år 2000. Data från Svenskt Näringsliv använd
UV irradiation is getting increasingly popular as a disinfection step in drinking water production. Ringsjöverket, a drinking water treatment plant in Sweden installed a full-scale UV aggregate in December 2016. However, the effect of UV irradiation on drinking water has mainly been tested on specific pathogens in labscale environment. Heterotrophic plate counts are often used when analyzing drink
Bovine milk contains several enzymes which can affect the quality of milk. One of these enzymes are lipases which hydrolyse the triacylglycerides in milk. In this process off-flavours, odour and product defects are generated. By controlling the enzymes activity, milk quality can be increased and therefore milk and dairy products can be stored for a longer time. This is desirable since the world de
Within the last century, a continuous decline in global insect pollinator populations has been observed. The loss of pollinating insects is not only important for their conservation value in itself, but entails far-reaching consequences of pollination deficits. This development is mainly associated with anthropogenic environmental disturbances, leading to fragmentation and loss of natural habitats
Tågtrafiken är betydelsefull för dagens samhälle, både för transport av människor och gods. I takt med ökad efterfrågan har en trafikökning skett på Sveriges järnväg. Det är trafikledarens ansvar att leda tågen på ett säkert och effektivt sätt och se till att den dagliga driften fungerar. Yrket som trafikledare ställer stora kognitiva krav såsom uppmärksamhet, koordinering och problemlösning. Traf
Fiber-reinforced polymer matrix composites are being used increasingly in lightweight applications where high strength and stiffness is required. One of the main challenges with designing components from such materials is to predict the ultimate strength and behaviour of the structure. Furthermore, due to anisotropic material response and a complex micro structure, various interacting failure mode
Materialflödet som uppkommer i och med dagens nivåer av konsumtion och global handel har gjort att avfallshantering och en effektivare hushållning med jordens resurser blivit allt viktigare. Idag ligger därför stort fokus på att förebygga uppkomsten avfall eller i annat fall återanvända eller återvinna tillverkade produkter. En sektor som använder stora mängder av just jungfruligt material är bygg
Till följd av en ökad globalisering och avregleringar av de handelshinder som tidigare låg till grund för EU:s marknad, har nya flexibla företagskonstruktioner vuxit fram på arbetsmarknaden. En snabb utveckling inom företagsstrukturer har emellanåt lett till att skyddet för de arbetstagare som omfattas av en verksamhetsöverlåtelse har kommit i skymundan. Det rådande direktivet 2001/23/EG tillsatteAs a consequence to the increased globalization and deregulation of trade restriction which previously ruled within the EU market, new flexible corporate structures have risen within the labour market. The swift development within the corporate structures has occasionally led the rights of the employment to be left in the dark in cases of corporate acquisitions. The reigning directive 2001/23/EG w
Utbildning är en viktig del av vårt samhälle och med hjälp av ny teknik finns det utrymme för förbättring. Idag används datorer, applikationer till smarta telefoner samt surfplattor i stor utsträckning inom utbildning. En ny teknikrevolution håller på att äga rum, nämligen Virtual Reality. Detta examensarbete undersöker användbarheten för Virtual Reality som utbildningsverktyg. Eftersom Virtual ReEducation is an important part of our society and with technological advancements there is room for imporvement. Computers, smartphones, tablets and applications are widely spread as educational tools in todays classrooms. A new technological revolution is about to happen, which is called Virtual Reality. This thesis examines the usability of Virtual Reality as an educational tool. Since Virtual R
This thesis presents and evaluates nineteen methods for combining up to eleven automated univariate forecasts. The evaluation is made by applying the methods on a dataset containing more than 1000 monthly time series. The accuracy of one period ahead forecasts is analyzed. Almost 3.2 million forecasts are evaluated in the study. Methods that are using past forecasts to optimally produce a combined
Under mina sista år som student på arkitektskolan i Lund har jag flera gånger stött på något som jag uppfattar som en diskrepans mellan människors upplevda trygghet av och den statistiskt kartlagda säkerheten för ett givet rum eller plats. Det är för mig intressant hur ett ställe som Stureplan i Stockholm, berömt för dess nattliv men också ökänt för dess höga nivåer av kriminalitet, kan uppfattas
