Detecting travel modes from global navigation satellite system (GNSS) trajectories is essential for understanding individual travel behavior and a prerequisite for achieving sustainable transport systems. While studies have acknowledged the benefits of incorporating geospatial context information into travel mode detection models, few have summarized context modeling approaches and analyzed the si

The decarbonisation of existing building stocks increasingly depends on renovation, with one-stop shops (OSS) emerging as prominent delivery models designed to reduce complexity and accelerate uptake. However, prevailing renovation strategies remain dominated by performance-oriented paradigms that prioritise modelled energy performance targets and efficiency ratios, understood in energy use per un

In this paper, we propose the design of a roof-glass integrated microstrip antenna for vehicular SDARS tuners. The proposed microstrip antenna is sandwiched inside a multi-layer roof glass and uses a solar-heat reduction coating on the bottom side of the glass as ground plane. To offset the effect of the lossy glass, parasitic elements are added to enhance the antenna gain. Simulation results show

The aim of this study was to examine if Landsat TM data could be used to : (I) estimate autumnal rape seed area (II) study the wintering of autumnal rape seed (III) estimate autumnal rape seed yield. The study took place in the province of Scania, Sweden. Two Landsat TM scenes, registrated 85-11-08 and 86-05-03, were included. The scenes were radiometric and geometric corrected in an image proces

This thesis explores the UTVs (Utility Terrain Vehicle) transition from internal combustion engines to electric drive and how the shift will impact Atlas Copco as an assembly tool manufacturer. Research is conducted based on a mixed-method approach, using both semi-structured interviews with key manufacturers and Atlas Copco sales engineers, as well as a multiple case study at manufacturing plants

Cameras mounted on boats and in other similar environments can be hard to use if waves and wind cause unwanted motions of the camera which disturbs the desired image. However, this is a problem that can be fixed by applying mechanical image stabilization which is the goal of this thesis. The mechanical image stabilization is achieved by controlling two stepper motors in a pan-tilt-zoom (PTZ) camer

Most of the increase in world electricity demand until 2030 is expected to come from developing countries (IRENA, 2016) and transition to carbon free energy production technologies offers the opportunity to reduce the negative effects of this increase. With majority of the low and middle income countries located in the areas of favourable solar radiation, PV technology is likely to become a key so

To form a building adapted to the environment and at the same time preserve land, water and other resources in a long term it has to fulfill some requirements. Requirements are set by international and national governing authorities. In order for a regular consumer, property owner or entrepreneur to be guided towards sustainable construction, there are also several environmental certification syst

Under år 2017 gjordes SVT:s morgonprogram Gomorron Sverige om till Morgonstudion. Det nya programmet blev bemött av blandade åsikter. För att ta avstånd från den rådande kommersialiseringen av mediesfären valde SVT att satsa på ett program som ger ett bredare perspektiv och fler infallsvinklar på nyhetsrapporteringen. Uppsatsen syftar till att undersöka utvecklingen av programmet efter övergången

This thesis addresses overvoltage issues in weak low voltage grids caused by large solar power production. The suggested method is using PI controllers to control voltage. This is done by using battery energy storage systems (BESS), designed to absorb active power during these times and thereby limiting the voltage rise. This could enable faster integration of solar power and a reduced demand for

Wheat bran is a by-product from the production of wheat flour. Nowadays wheat bran is mostly used as feed for animals, in the food and baking industry or it is simply burned in open air. However, wheat bran could be used in biorefineries for production of value-added products such as bioplastics, biofuels and chemicals as a substitute for fossil feedstocks as petroleum. Since wheat bran is an agri

Examensarbetet jämför tre olika metoder för dimensionering av en spont. Syftet med arbetet är att utreda hur de valda beräkningsmetoderna inverkar på dimensionerande snittmoment och dimensionerande förankringskrafter samt att undersöka hur resultaten från de olika beräkningsmetoderna varierar vid ändring av ingående parametrar. De tre beräkningsmetoder som jämförs är den analytiska metoden från SThis master thesis compares three different methods for dimensioning a sheet pile wall. The purpose is to investigate how the chosen calculation methods affect dimensioning moments and anchoring forces in a sheet pile wall and to investigate how the results from the different calculation methods vary when changing the input parameters. The three calculation methods that are compared are the analy
