The development of energy has an impact on the evolution of travel modes. With the iterative update of electrification on private and public transportation, micro-mobility has always been one of the essential options to support cities and commuters. With the explosive growth of shared transportation in the past decade, many companies have invested in the sharing economy market. In order to crea
Den 23 september 2020 lanserade EU-kommissionen den nya asyl- och migrationspakten, där fem nya lagförslag presenteras, som bland annat syftar till att förhindra att asylsökande utan tydliga asylskäl får resa in i Europeiska unionen (EU). För att uppnå det här målet föreslår EU- kommissionen att inrätta en fas före inresa, som kommer att bestå av en fem-dagar lång screening av alla tredjelandsmedbOn the 23 September 2020 the European Commission launched the Pact on Migration and Asylum, introducing five legislative proposals, which inter alia aim at ensuring that only people with clear protection needs enter the European Union (EU). To reach this objective, the European Commission introduced a so-called pre-entry phase, consisting of firstly, the proposed screening procedure, a five-day pr
Marine materials are a potential new raw source for the production of organic and vegan leather and cushioning materials. Being a carbon sink, seaweed and marine plants like seagrass and seaweed farming activity could have a crucial role in the current environmental crisis for the absorption of carbon dioxide in the atmosphere. Products extracted from brown and red seaweed can be used for the prod
The entrepreneurship ecosystem in Skåne, Sweden is dynamic with many activities and support for new ventures, and it boasts a wide range of actors. However, there is a lack of empirical research on how the process leads to the success of entrepreneurs in terms of how productive ventures are, how beneficial it is to entrepreneurs and whether there is economic and social contribution to entrepreneur
If we think of footwear as a product that our feet when we run, jump and walk bilities that could have in the future? Triggered by the trail running, this project explores the possibilities of footwear that can quickly provide users with different levels of frictional transition under varying road terrains. Through an innovative exploration of the internal structure of the footwear midsole, c
The brown bears, Ursus arctos L., in the Scandinavian peninsula were distributed in almost all counties before aimed reduction during the 1700-1900s (Swenson et al. 1995). From 1981-2013 the population increased more than five times (Chapron et al. 2014) to about 3000 individuals (Kindberg et al. 2014). The aim of the master thesis was to find the geographical expansion rate in this bear populatio
Title: Comparing single- and multi-echelon methods for inventory control of spare parts at Volvo Authors: Jakob Bengtsson & Alexander Larsson Supervisors: Johan Marklund, Lund University | Christian Beckers & Johan Lid- vall, Volvo Background: Spare parts logistics is an area particularly concerned with challenges related to inventory control. The parts are vital to secure the functionalit
Fishway construction remains a crucial measure in environmental adaption of flow barriers. A well-functioning fishway should be able to pass all naturally occurring species of fish and other aquatic fauna. A common approach when designing and dimensioning a nature-like fishway is to calculate flows with Manning’s equation but the selection and impact of Manning’s roughness coefficient lacks a robu
Segregation är ett vanligt fenomen som uppstår över hela världen. De negativa konsekvenserna av boendesegregation har visat sig vara många för de som bor i mindre välbärgade stadsdelar. Bland konsekvenserna finns bland annat hälsorelaterade motgångar, men även sämre förutsättningar under skolgången och i det framtida arbetslivet har konstaterats. Sydafrika lämpar sig väl för att studera segregatioSegregation is a common phenomenon arising worldwide. Residential segregation has been shown to have several negative consequences for people living in less wealthy neighbourhoods, such as health-related setbacks and being less likely to cope with school. South Africa is an especially well-suited country to study segregation and methods to counteract it to achieve better integration and more harmo
Detta examensarbete genomfördes i samarbete med AFRY och deras kund Homezan som specialiserar sig på design av möbler producerade i naturmaterial. Bakgrunden till arbetet myntades genom företagets önskan att utöka deras produktsortiment med hallmöbler. Därmed har detta examensarbete fokuserat på att utveckla ett hallmöbelkoncept med fokus på att identifiera företagets målgrupps förvaringsbehov. UtThis Master Thesis project was performed in collaboration with AFRY and their client Homezan, who specializes in home furniture design produced in natural materials. The project scope emerged from the company’s request to expand their product assortment to hall furniture. To solve this request, this Master Thesis project a hall furniture concept have been developed with focus on identifying custom
This thesis considers an investigation into the possibilities of creating a reasonably accurate multiscale material model for paperboard, with geometry based on X-ray scans of small paperboard samples. The modeling takes place in the software Multiscale Designer by Altair Engineering Inc. A representative volume element (RVE) is used to capture the X-ray geometry and represent macroscopic mechanic
An Artificial Neural Network (ANN) is a type of machine learning algorithm with widespread usage. When training an ANN, there is a risk that it gets overtrained and cannot solve the task for new data. Methods to prevent this, such as L2-regularization, introduce hyperparameters that are time-consuming to optimize. In this thesis, I investigate a hypothesis which postulates how the optimal L2-regul
Machine learning, alongside other branches of AI have entered an era of rapid growth in several industries including healthcare, creating vast opportunities to advance several aspects of clinical practice. Specific to clinical decision support, despite the immense potential benefits of incorporating machine learning into clinical decision support systems, also known as machine learning enabled cli
Machine learning and artificial neural networks can be used to classify or detect specific sound events in audio signals. Gunshot detection is one use case for such networks and can be used to help law enforcement by alerting officers or triggering camera recordings. However, artificial neural networks with a high performance usually require large amounts of computational power, meaning that they
Problem description: At Scania in Oskarshamn, there is a phenomenon referred to as external picking. External picking is in the context of this report defined as the process where stock-keeping units, not intended for the main production lines, are picked at one of Scania’s Oskarshamn facilities. These items are intended for various organizations within Scania, but also external business partners.
Mosasaurierna utgör en grupp storvuxna ödlor som dominerade positionen som toppredatorer i haven under sen krittid. Det anses allmänt att dessa marina reptiler, tillsammans med de sista landlevande dinosaurierna, dog ut under det massutdöende som markerar övergången mellan krita och paleogen. Nyligen påträffades en del av ett skalltak tillhörande en mosasaurie i ett löst kalk- och flintblock på enMosasaurs are a group of marine reptiles that are considered to have been the apex predators of the oceans during the Late Cretaceous. It is generally assumed that they, along with the last non-avian dinosaurs, died out during the mass extinction that marks the end of the Cretaceous. Recently, a mosasaur skull roof was discovered in a loose boulder on a beach in the vicinity of the town of Hanstho
