En traktor med skogsvagn är ett tämligen stort ekipage som i skogen sällan har gott om plats att ta sig fram på. För att göra det möjligt är många skogsvagnar utrustade med en extra led på dragstången, så kallad vagnstyrning. Denna led används för att förskjuta vagnen i sidled och därmed anpassa dess färdväg. Detta är mycket användbart i skogen då det medför att, med rätt inställning, vagnen följeA tractor with a forest trailer is a large vehicle combination. When it is driven in the woods there is not a lot of space. To make it possible to turn in limited spaces forest trailers are equipped with an extra joint on the drawbar. This is called drawbar steering. This joint changes the geometry of the trailer in order to make it take another path. This feature is very convenient in the forest

En växande världsbefolkning, politiska regleringar och en strävan att öka andelen energi från förnyelsebara källor har resulterat i att intresset för vindkraftsverk ökat. Winfoor AB utvecklar `Triblade’, en ny teknologi för vindkraftsverksblad som ämnar öka effekten samtidigt som bladen kan göras lättare, billigare och enklare att transportera än dagens vindkrafsverksblad.A globally growing population, an increased energy consumption and growing environmental awareness have made the interest for renewable energy sources, such as wind power, higher. As a result of the increased demand the need for new and improved technologies have increased. The energy production of a wind turbine is highly affected by the rotor blade length, which is limited by the massive dead lo

This paper analyses the impact of inflation targeting as a monetary policy framework on inflation volatility and inflation rates in Uganda, with a comparison with South Africa and Ghana (full-fledged inflation targeting economies) and Kenya that opted for a forward looking monetary framework. The results show that inflation targeting in Uganda has been efficient in reducing inflation volatility an

Today’s network outdoor surveillance cameras face problems when water drops stick to the protective glass in front of the camera lens, thus significantly disturbing the image. This problem mainly occurs during heavy rain weather or when the camera is being cleaned with a hose. Solving this problem would greatly improve the performance and versatility of outdoor surveillance cameras. The way this p

The incineration furnace at National Veterinary Institute (SVA) in Uppsala, Sweden, runs approximately 2,150 hours a year and generates a large amount of waste heat. Some of this heat is partially recovered, and is used for heating one of the main buildings during the furnace operation. However, around 2,000 MWh is wasted annually due to unavailability of any storage system. This wasted heat is ap

Stora delar av bostadsbeståndet i Sverige är uppfört efter modernistiska planeringsideal med uppluckrade gränser mellan det privata och publika. I dessa miljöer är alla ytor inte direkt avläsbara ifråga om ägarförhållanden och användning. I många fall är det inget problem, det kanske finns tillräckligt med ytor för alla,underförstådda överenskommelser regleraranvändning effektivt, men i andra fallA great part of the Swedish housing stock is built according to modernistic planning ideals where boundaries between public and private propertiesare not always visible, neither in ownership nor in use aspects. In many cases this is not a problem, there is plenty of space for everyone and implicit agreements regulate use, but in other cases areaswon’t be used, conflicts occur or fences will close

This thesis aims to create a simple evaluation tool suited for assessment of value creation in Circular Business Models (CBMs). Transitioning from a linear business model to adapting the Circular Economy principles, brings in a range of new challenges, for both a company and its consumers. However, it is also important to note the different opportunities of value creation that arise due to such a

The notional amounts outstanding of over-the-counter (OTC) derivatives had grown exponentially for almost two decades and its rapid growth were mainly due the increase in OTC interest rate derivatives. As of december 2014, the total notional amounts outstanding in the global OTC market was 630 trillions USD and the OTC interest rate derivatives represents about 80% of the market. Trading with OTC

Partikelfysik är den del av fysiken som beskriver de allra minsta beståndsdelarna i vår värld. De ekvationer som används för att beskriva dessa små partiklar kan vara mycket svåra att lösa, det finns faktiskt ett pris på en miljon dollar till den som lyckas lösa ett visst problem inom partikelfysik. För att underlätta alla beräkningar som ska utföras, så har fysiker tagit fram några regler som manSolitons are solutions to classical field equations that are particle like, meaning they are localized in space, have definite energy and can be stable against deformations into the vacuum. In this thesis we investigate under which circumstances such solutions may exist and what effects their existence could have. It will turn out that topological considerations will play a large role in the quest

Small biological airborne particles (aerosols) reside in the atmosphere and can influence human health, the climate and the environment. Whereas aerosol sampling technology is well-known, there is currently no satisfactory high-volume flow impinger for health and atmospheric monitoring applications. The aim of this thesis was to design and construct a working prototype of an impinger, a sampling d

Today, it seems as if every second designed object is referred to as timeless design. We use the word timeless as a selling word without really thinking about what it means. Through investigating the concept of timeless design, I found the physical paper book being probably one of our most timeless objects. There are tons of book storing furnitures on the market of which the majority consists of

Foreign direct investments (FDI) have in later years become regarded as a key engine to economic growth, which many developing countries find appealing. Developing countries do however often find it hard to attract FDI since they have an unstable political environment due to inferior levels of democracy. To overcome this issue, they turn to bilateral investment treaties (BITs) with the hope that t

The aim of this Master’s thesis is to research the presence of lesbians in historical archives. My material consists of interviews with four swedish archivists. The aim of these interviews is to research the priorities and the work that is beeing done at the archives concerning collecting material that is missing in the archive and making existing material related to lesbian lives accessible. Fu

The aim of this Master's thesis is to investigate the choices that legal deposit libraries in Sweden make, during the process of collecting and displaying printed ephemera. The word “ephemera” originally derives from a Greek word simply meaning “short-lived” or “lasting only for one day”. The term “printed ephemera” thus refers to a wide range of different documents meant to be discarded after

Barriärer och möjligheter för klimatkrav vid upphandling av infrastruktur Att ta hänsyn till klimatpåverkan vid byggnation har på senare år blivit en del av den offentliga upphandlingen. För att nå Sveriges uppsatta mål om att vara utan nettoutsläpp av växthusgaser 2050, måste en förändring ske i alla led i samhället. Formulering av klimatkrav vid upphandlingen borde väl därför kunna användas somClimate change is one of the biggest challenges facing today's society. The construction sector contributes with a substantial part of the country's carbon dioxide emissions and accounts for a large part of Sweden's public procurement. Setting environmental requirements is therefore a very important part of the procurement process to ensure that the production of buildings and infrastr

The purpose of this study is to investigate the influence of non-conventional violence on the implementation of disaster risk reduction projects in the Northern Triangle of Central America. The Northern Triangle is facing substantial disaster risk from various hazards. Hence, there is a need for disaster risk reduction in the region. However, besides the challenges in terms of disasters, this regi

I det blomstrande forskningsfältet om planeter och exoplaneter, det vill säga planeter utanför vårat eget Solsystem hittar vi konstant nya planeter och system som alla ger oss pusselbitar till att förstå hur planeter formas och utvecklas. Så för att förstå de observationer vi gör och bedöma hur sannolikt det är att det kan finnas liv på en planet, måste vi förstå alla olika typer av system och hurIn the thriving field of exoplanet research new discoveries are made all the time, and while most of the observed systems can be explained with classical planet formation models - some are much harder to explain. When stars form they are often surrounded by the remaining material of the nebulae they formed from. Some of this remaining material forms into a protoplanetary disk around the protostars

A fleet of autonomous sailboat could change our perception of the planet. An autonomous sailboat could not only conduct environmental research but also perform month long operations through the energy efficient wind propulsion. This thesis is the work behind the development of an autonomous catamaran model sailboat. A new mathematical model is brought forward and implemented for simulations perfo
