Sammanfattning Grundprincipen för utrymningsdimensionering är att tiden det tar att utrymma en byggnad ska vara mindre än tiden till kritiska förhållanden uppstår. Enligt Boverkets byggregler kan en inåtgående dörr till lokaler som rymmer fler än 30 personer bidra till köbildning vid utrymning, därför föredras att dörren öppnas utåt. Tvärtemot Boverkets byggregler är en utåtgående dörr vid vissaAbstract The purpose of the study was to investigate if the inwards door in a room that holds more than 30 people leads to queue formation. Queuing can lead to prolonged evacuation, which increases the risk of people still being in the room when critical conditions arises. In this study, movement times with inward and outward opening doors were examined as well as queuing in both directions. The s

When insurance companies calculate compensation for products no longer on the market, they need to identify an equal product for val- uation. Subjectively matching products poses a unique challenge with a many-to-many pairing, which is currently handled by an algorithm that requires day-to-day maintenance. This thesis investigates current methodologies and tools and presents unique machine learninInsurance companies manually find replacements for thousands of products every day. Can a machine replace the manual labor while remaining faithful to the consumers’ desires?

Three non-symbiotic hemoglobins (nsHb) have been identified in Beta Vulgaris (sugar beet). These are hexacoordinated Hbs with high oxygen affinity. The spectral properties for one of these, BvHb1.1 was analyzed and its molar absorption coefficients determined. Furthermore, an initial safety analysis was carried out by studying the cleavage of plasmid DNA (pDNA) induced by these proteins. The resul

Climate change adaption is becoming more and more crucial within sustainable urban design. Global warming affects an increase of heavy rainfall events in Europe and especially in Germany. Deggendorf, a city in southeast Germany, has experienced a severe flood in 2013 caused by a dike burst. The chosen site in Deggendorf lies next to a dike park and has unused potential to be developed. The thesis

Background In traditional retailing, where the challenge lies in providing goods in a store with limited space while minimizing tied up capital and obsolescence, good inventory management is often an important competitive advantage. However, the emergence of the online channel changes some of the challenges, and the associated requirements on inventory management. These dierences are studied in th

In today’s connected world, businesses are increasingly going online. Additionally, the online industry is transforming into an international business arena, flourishing with opportunities to grow and expand. However, the internationalisation has raised a number of challenging issues. One of these challenges is foreign exchange. Foreign exchange is needed to sell and buy on markets with different

Bakgrund: Det har skett en förändrad marknadsmiljö hos patentbyråerna idag, i alla fall för de större byråerna. Förr agerade patentbyråerna mer som ordermottagare, efterfrågan var stor i förhållande till antalet aktörer på marknaden. Vilket gav patentkonsulterna en starkare position i förhandlingarna med kunder. Detta har förändrats, på senare tid har det krävts mer arbete från patentkonsulter

Bakgrund Vid gruvdrift uppstår miljöfarligt avfall i form av gråberg som innehåller metaller som kan urlakas. Avfallet kan oskadliggöras genom att lägga ut tät morän som ett vattenhållande tätskikt kring gråbergsupplaget. Transportkostnaderna för detta är oftast höga då morän av tillräcklig kvalitet måste hämtas långt ifrån upplagen. Studier har visat att kvaliteten på morän kan förbättras genom a

Evaluating and testing changes or configurations to peer-to-peer systems or even understanding their behaviour can be complicated. One approach is to simulate a large peer-to-peer system and visualise the results. In this master's thesis a study is performed to understand how an actual implementation of a hybrid peer-to-peer live video streaming system behaves and performs under different scen

The ability of testing on-chip circuitry is extremely essential to ASIC implemen- tations today. However, providing functional tests and verification for on-chip (embedded) memories always poses a huge number of challenges to the designer. Therefore, a co-existing automated built-in self-test block with the Design Under Test (DUT) seems crucial to provide comprehensive, efficient and robust testi

The United States middle class has become a major topic of discussion and debate over the past several years, playing an intricate part in economic and political policies today. The reasoning behind this is due to the acknowledgement of the average American household struggling to maintain their standard of living with rising costs of goods and services along with stagnating wages. Unemployment is

Då en make ärver en make med släktingar i första eller andra parantelen uppstår arvsrättsligt en efterarvsrätt. Denna efterarvsrätt har tidigare inte förtydligat huruvida en försäkringsersättning som utfaller genom förmånstagarförordnande till efterlevande make ska inräknas i efterarvet. 1975 kom ett rättsfall från högsta domstolen som fastställde just detta, att det faktiskt föreligger rätt till When a spouse inherits another spouse, who has children from a previous marriage, parents, siblings or nephews alive, a right to secondary inheritance occurs according to Swedish law. Before 1975, it was not clarified whether this right to secondary inheritance should include an insurance reimburse-ment due to an insurance with a spouse as beneficiary. In 1975 the Swedish Supreme Court ruled that

Matsvinn är ett problem med miljömässiga, ekonomiska och sociala konsekvenser. Nära en tredjedel av maten som produceras i världen idag kastas eller förstörs, något som är ohållbart av en mängd anledningar. Ett forskningsprojekt som drivs för att åtgärda detta är DynahMat-projektet på Lunds Universitet. DynahMat föreslår användandet av temperaturindikatorer och andra sensorer för att beräkna en prFood waste is a problem with environmental, economic and societal aspects. Up to a third of global food production is wasted every year, something that is unsustainable in many ways. Much research is currently being done to alleviate the problem. The DynahMat project at Lund University proposes using temperature indicators and sensor technology to improve food supply chains and provide a more accu

In this thesis the approximation properties of feedforward articial neural networks with one hidden layer and ReLU activation functions are examined. It is shown that functions of these kind are linear splines and the number of spline knots depend on the number of nodes in the network. In fact an upper bound can be derived for the number of knots. Furthermore, the positioning of the knots depend o
