The purpose of this project was to create an object that improves the performances of football players, preferably on all levels, be it professionals or amateurs. The main theme was science and technology, to explore how they together can be used to accomplish this task. The project consisted of doing research on site at amateur football clubs, which included observations of training sessions a
Tin whiskers have long caused issues to electronic components and made the subject of many articles. According to NASA the oldest reports concerning whiskers date back to the 1940's. The whiskers are single-crystals growing from, for example electronic components. Despite the long history of tin whiskers the actual cause of their growth is still unknown. The hypothesis held by the author is th
As a de facto leader in corporate governance and sustainability reporting (SR), this study provides a thorough and comprehensive characterisation of SR among the UK’s leading companies. A content analysis was undertaken of key corporate communications across a sample of 66 constituents listed on the London/ Financial Times Stock Exchange (FTSE) 100 index. Through a systematic analytical framework

När en betongpelare dimensioneras ska dess kritiska tvärsnitt bestämmas och dimensioneras med hänsyn tagen till pelarens slankhet och andra ordningens effekter. Dessa parametrar kan begränsa pelarens bärförmåga och riskera knäckning istället för att tvärsnittets kapacitet blir avgörande. För att uppskatta pelarens slankhet beskrivs i Eurokod t.ex. den nominella styvhetsmetoden och den generella meWhen designing a concrete column, the critical cross section must be determined with regard to the column slenderness and second order effects. These parameters could limit the columns resistance by the risk of buckling instead of the cross sections resistance deciding the limit state. Eurocode describes among three methods the nominal stiffness method and the general method to approximate the sle
Humanitarian organizations (HOs) are the main authority in long-term refugee camps. However, literature criticizes the economic relevance of HOs in a long-term refugee camp. My thesis applies the discussion to a case study in Kakuma camp. The study proposes two research questions: 1) To what extent does the long-term presence of HOs affect the market system and economic life of refugees in Kakuma
The galloping pace of development in the field of wireless communication has left the world astounded over the last decade. But this has also led to a wild and inexcusable extravagant expenditure of energy. Due to the dynamic nature of wireless network, it has become imperative to focus more on energy efficiency and achieve desired Quality of Service (QoS). The challenge of diminishing the carbon
Transport planning has been in favour of and prioritised motorised transport for almost a century. During this time, cars have been given street space at the expense of more sustainable transport modes. The auto-normative paradigm thus created a spatial imbalance, an injustice, in the amount of space that are devoted to the different transport modes. The main objective of this thesis is to analyse
Currently most aromatic compounds used in industry are derived from unsustainable petro-chemical feedstock. However the depolymerization of lignocellulosic biomass generates a wide range of aromatic compounds that could be further valued through microbial conversion with microorgansims such as the bacterium Pseudomonas putida. The aim of the present project was to develop a reproducible methodolog
The purpose of this journal is to further investigate how a brand, during a limited time frame, can change an unwanted image by challenging the stereotypical perceptions of their brand by adding an element of surprise. The research is conducted through a multiple-case study consisting of four cases: Mercedes-Benz, Opel, McDonald’s and Lidl. A resulting matrix has been developed to demonstrate the
Background/introduction: E-commerce is becoming a natural part of retail business. In order to achieve a competitive edge, companies are shifting to omni channel retailing where channel integration is explored in the search for potential improvements in connection with customer offer and costs. One solution is to integrate inventories and offer improved order fulfilment by using both warehouse and
Purpose: The aim of this paper is to explore how brands’ greening strategies affect consumers’ green brand image. Design/Methodology/Approach: This study is based on a qualitative approach, researching one case, McDonald’s greening strategies compared with the consumers’ brand image. The consumers’ brand image was collected with the help of 12 semi-structured interviews. Findings: The research s
Pavements in Sweden today are often designed to have a life span of at least 20 years. This means that pavements are designed to endure all seasons for 20 years: 20 winters, 20 spring thaws. 20 summers and so on. For those occasions where a life span less than 20 years is requested, there is no standardized method to use today. Designing is instead usually done either by scaling down the results f
The aim of this essay is to investigate two scholastic theologians’ views on usury, to compare their arguments for the Christian usury prohibition and to see whether one can see a development in argumentation. The examined writers are St. Thomas Aquinas and Gerard of Siena and their works Summa Theologiae, De Malo, and De Emptione et Venditione; and De Usura, respectively. Before the investigation
Vad är det som gör att en människa är benägen att utsätta sig för de risker som finns i att vara kriminell, vad är mentaliteten under tiden och hur kommer man ur det. Uppsatsen berör processen för individer som valt att inleda, upprätthålla och avsluta en kriminell karriär. Detta undersöks genom intervjuer med fyra stycken före detta kriminella personer. Genom denna kvalitativa uppsats söktes pers
De senaste årtiondenas utveckling av svensk arbetsmarknad och arbetsmarknadspolitik har gjort att fler grupper förväntas klara sin försörjning genom arbete. Flera förändringar har genomförts som tillsammans innebär att fler arbetslösa blir kommunernas ansvar vilket har lett till att allt fler kommuner i växande utsträckning bedriver arbetsmarknadsåtgärder. För personer som anses befinna sig längst
Algoritmer för att automatiskt förstå innehållet i bilder och videor har sett en enorm utveckling under de senaste åren. Trots framsteg i hur väl algoritmerna kan läras till att förstå bildinnehållet på egen hand så krävs fortfarande en viss grad av handhållning och vägledning från områdesexperter som utvecklar och tränar algoritmerna. När positionen och dimensionerna på ett objekt av intresse skaThis thesis presents a novel matching strategy, Inflated Multinomial Matching, which enables training of anchor-free object detection models based on convolutional neural networks. An important aspect of detection models is the integral usage of anchor boxes, where an anchor box is a bounding box with a preset and constant location, size and shape in the image. The matching strategy presented remo
Transparenta material som kan leda ström är viktiga för bland annat solceller. Nu har ett sådant material, indiumtennoxid (ITO), för första gången tillverkats i rekordliten storlek för att användas till exotiska solcellsprover på nanoskalan. ”Konventionella” solceller lider av ett problem som kan liknas vid grötproblemet Guldlock stötte på hos de tre björnarna: när solen lyser på solceller kommerNanowires have attracted interest as fundamental building blocks for electronic and optoelectronic devices as well as for fundamental research. Photonic studies of single nanowire devices typically involve patterning of metal electrodes for electronic access, yet plasmonic ef- fects between the metal contacts and the light source may perturb experimental measurements. An alternative to conventiona
The aim of this thesis is to suggest a statistical model to estimate the loss rates of honey bees during winter in Sweden. The estimator is to be based on annual summary statistics, collected by the Swedish beekeeping organisation. Regional specific estimates for winter loss rate is derived by a spatial and temporal hierarchical model with binomial response. The model is updated by Bayesian infere
