Bumble bee compound eye sizes in different climates Bumble bees are important pollinators with over 250 species spread over the world. One could even argue that they are the cornerstones of life as we know it, considering their immense task of pollinating almost everything we eat, as well as everything that what we eat eats. But how does the bumblebee do all this, in all these vastly different p

Suitability of Dynamic Latches for Sub-VT Operation Sina Borhani Soc11sbo@student.lu.se Department of Electrical and Information Technology Lund University In the past the major concerns of VLSI designers were the performance and area of electronic devices but right now because of technology scaling in CMOS and also with the substantially growth in portable computing gadgets like smart phones

Understanding neoliberalism as a many-headed heterogenous global tendency, this thesis aims to investigate, analyse and gather lessons in the global resistance against it. It is particularly focused on Pirin National Park in Bulgaria, where government changes to its management and development have sparked year-long protests. I ask how neoliberalism manifests itself in Bulgarian environmentalism an

The purpose of this work was to use spatial-temporal analysis for the prevention and mitigation of disease spread. A prototype application was specifically designed to detect territories with a high incidence of cases and a second was used to validate the results. The first algorithm tried to find clustered cases territories and compare them to the smooth average of the previous two years of data

Can Machine Learning Provide more Insights in Cardiovascular Disease? Cardiovascular (CV) disease is the main cause of morbidity and mortality all over the world and the number of people suffering from CV complications is growing as the population is getting older. Despite of knowing several risk factors such as age, hypertension, body mass index (BMI) and genetics associated to CV complication,

Sweden has the reputation of being one of the most sustainable and innovative countries in the world, when it comes to environment-related technology. However, the ecological footprint rates indicate, that Swedes are currently living lifestyles that would require the equivalent of four Earth-like planets to sustain. Most carbon foot-print emissions are closely connected to household activities, wi

This study centres around the value creation and status hierarchies in online brand communites. With the advancement of digital technologies, it has become easier for admirers of brands to interact and communicate with each other. Companies do not necessarily want to engage and commit to online brand communities due to strict brand management practices and fear of losing the control of the brand t

This research focus origins from an international welcomed preschool cartoon Peppa Pig and try to fill in some blank areas of the Chinese Peppa Pig studies. Through the usage of two qualitative methods to explore Chinese audiences’ reception studies of British cartoon Peppa Pig. Qualitative content analysis has been used for understanding audiences’ Peppa Pig reception. After categorizing and codi

Purpose: This master paper aims to develop an eligible tool to reveal the gaps between brand identity and brand image, in order to address the issues between vision and image. Design/methodology/approach: Through literature review, the issues between vision and image, to some extent, have been determined by the inconsistency between brand identity and image. Researching three product brands, Louis

Purpose: The purpose of this paper is to examine how sponsorship crises can affect brands. Especially brands that have decided to part from their athletes are taken into account in this paper. Besides that, it aims to establish managerial guidelines that help to communicate the termination of sponsorship activities. Methodology: To understand the underlying theory, secondary data is gathered throu

This project studies with scanning tunneling microscopy (STM) if radicals can adsorb onto the surface of graphene flakes which had been intercalated with CO. To obtain CO intercalated flakes of graphene, flakes of pristine graphene are formed, and subsequently intercalated by a super dense “water” phase. This water phase allows for the intercalation of CO, where it is observed that flakes are inte

Much focus is being laid on vibrations in the building industry today. Many times these vibrations are externally induced and caused by placing buildings closer to existing sources, such as railways and roads, or new transportation systems closer to existing buildings. Vibrations can be disturbing to both humans and sensitive equipment in, for example, hospitals and laboratories. The simulations n

Grafdatabaser blir mer och mer populära. När populariteten ökar så önskas det att sökningar i grafdatabasen utförs snabbt och korrekt. Därför behövs det snabba och pålitliga sökalgoritmer för att genomföra sökningarna.This report covers the implementation and evaluation of a Breadth-First Search operand for the Neo4j graph database and the Cypher query language. The evaluation compared the pre-existing Depth-First Search operand with both a non-optimized and two different optimized Breadth-First Searches. The focus of this evaluation was the runtime and memory usage for the different operands and to find out fo

Det är februari. Det snöar kraftigt. På radion pratar dom om flertalet lastbilar som ligger vid sidan av vägen. Du sitter som på nålar i din bil och kör försiktigt fram över den snötäckta vägen. Du är rädd att du ska gå samma öde till mötes som lastbilarna. Men det sker inte. Din bil kör med lätthet fram genom snön. Varför?This master’s thesis investigates the possibility to integrate an existing vehicle model from Simulink into the main testing software, CANoe. The purpose of integrating this was to achieve autonomous testing of real driving scenarios in an electronic control unit. This would in turn simplify and thus improve the test environment and test procedure at BorgWarner. By utilizing a vehicle model simila

Syftet med detta arbete var att designa och bygga en externt driven proteshand. Handen ska helst ha en eller flera funktioner som inte finns hos andra protester. Den mänskliga handen är väldigt komplex, den innehåller över 30 muskler och minst 18 leder. Jämförelsevis har en komplex och rörlig kommersiell protes fem aktuatorer och elva leder, men endast en eller två kontrollsignaler. Allt som allt The purpose of the thesis was to design and build an externally powered prosthetic hand. The hand should preferably have one or more new functionalities not found in other prostheses. The human hand is very complex, it contains over 30 muscles and at least 18 joints. In comparison, a complex and dexterous commercial prostheses has five actuators and eleven joints, but only one or two control signa

Partiella differentialekvationer är ekvationer som beskriver hur tillstånd förändrar sig. Dessa uppstår naturligt när man modellerar omvärlden, från hur molekyler sprider sig i celler till hur galaxer roterar. Att lösa dessa ekvationer är ofta näst intill omöjligt, och man behöver därför approximera lösningar med hjälp av datorer. Det här arbetet fokuserar på en speciell metod för att approximera This BSc thesis focuses on trying to find approximate solutions to partial differential equations using the Fourier collocation method. This method uses Fourier basis functions to approximate the solution to a partial differential equation with periodic boundary conditions. Using Fourier basis functions, one does not need to use large matrices, which makes all computations relatively fast. Another
