Eutrophication is one of the most threatening issues to water quality in natural water. It can cause problems of the ecosystem, with for example, lowering the biodiversity of the community. The main reason for eutrophication in natural waters is the leakage of nutrients from nearby crop-fields. Too much of nutrients reaches the water and negatively interferes with the water community. To study the
Hydropower is developing fast across the globe to accommodate the increasing need for electric energy. It is generally considered to be a close-to-zero emission source of energy, but studies have shown that reservoirs and dams have a substantial emission of greenhouse gas, especially methane. Measurements of methane emissions from different reservoirs have very varying results, partly because of t
Open data is broadly expected to generate innovation and economic value for both the public and private sector. Though the diffusion of open data has kept a fast pace, knowledge of visualisation and points of access of open data remains low. Moreover, literature of the private-sector application of open data is still scarce. The first objective of this thesis is to increase the knowledge about the
Validation and improvement of chemical kinetic modelling require accurate experimental data. The over goal of the present work is to obtain accurate data by using techniques that have been previously implemented in common flames, e.g. of methane, and showed good performance to provide high-value input for model validation of dimethyl ether (DME) combustion. Measurements of laminar burning velocity
Aluminum blisters are a widely used packaging type in the pharmaceutical industry, including Elanco Animal Health Inc., a major player in the animal health business. Excellent barrier properties and convenience of usage to the consumers make it an ideal solution. Unfortunately, due to lack of innovation since its invention in the 1960s, there have been certain shortcomings in it use; like lack in
LDMX is a fixed target experiment designed to search for light dark matter. The experiment will search for dark matter signatures using missing momentum and energy in events with electrons scattering in the target. Part of the experimental setup in this search is a high granularity electromagnetic calorimeter to accurately measure the energies of recoil electrons. In this thesis artificial neura
With the advent of autonomous vehicles (AV) comes a plethora of new parameters to take into consideration in automotive design. Over the years, traffic signals and rules have developed in symbiosis, and are clear and easy to understand when the communication is between drivers. It is less clear between driver and pedestrian, especially when a pedestrian intends to cross the street. A non-verbal ag
Bakgrund: Miljön inom den psykiatriska och rättspsykiatriska vården är komplex och har visat sig ha betydelse för patientens aktivitetsengagemang och den psykiatriska behandlingen. Arbetsterapeuter har kunskap om hur individens aktivitetsengagemang påverkas i olika miljöer och en kartläggning av miljöns betydelse ansågs därför relevant ur ett arbetsterapiperspektiv. Detta för att bidra till aktivi
Klädindustrin är en utav världens största och mest resurskrävande industrier, och den ger upphov till ett stort avtryck på både miljö och samhälle. Pressen på att agera hållbart ökar kraftigt, vilket ställer företagen inför stora utmaningar. Medvetenheten att de bör agera mer hållbart ökar likaså men det tycks finnas stora svårigheter i att överföra medvetenheten till handling. Vidare har det visa
Turbomachinery design is based on multiple physical thermodynamical relations and fluid mechanics. Software implementing these relations in computing fluid flows have been broadly accessible since the 1990’s and has also become more applied to turbomachinery design. However, the software is unfortunately a large expense on research and development departments. Cambridge Professor Emeritus John D.
The Theory of Change (ToC) approach has become popular among the international development community, emerging as a need for organizations to carry out more effective initiatives in the context of an increasingly complex world. The levels at which a ToC process can be aimed are worldwide, organizational, thematic and program or project level. The purpose of this study is to generate a better under
Tuberculosis (TB) and other mycobacterial infections have become more difficult to treat since the strains need to be screened for resistance. Furthermore, the half-year long treatment time could harm hepatocytes as a side effect of the treatment. This calls for discovery of new compounds for a successful treatment. One such promising peptide was recently discovered and called NZX. In this study
Purpose – The existing literature of open innovation (OI) has focused mainly on large companies and few on SMEs, leaving start-ups with scarce analysis of the use of OI. This paper aims to close that gap and contribute to a better understanding of what drives start-ups to open for innovation, how they use it and comprehend what challenges and benefits OI brings to start-ups.

Understanding and being able to quantify sitting postures is a central asset in car safety evaluations. This is due to the fact that passengers can choose a range of different sitting positions. Studying and understanding how passengers choose to sit to obtain some comfort is important for increased safety in futures cars and is particularly challenging facing a heterogeneous population. Data is a
While industrial robots have traditionally been designed for tasks such as pick-and-place that require a high repeatability, an increasing demand for off-line control and high-precision applications have in recent decades put higher demands on the accuracy of robots. One application in that vain is the detection of X-rays that have been scattered from a sample during X-ray diffraction, which produ
Due to its high vulnerability, permafrost is one of the key features studied in the field of climate change impacts. Permafrost is widespread in the Arctic region. The majority of the area underlain by permafrost is however difficult to access for in-situ monitoring and it is difficult to get an overview of the current state of permafrost in many areas. Permafrost modeling provides a solution whi
Det digitaliserade samhället har bidragit till nya förutsättningar och nya arbetsstilar vilket resulterat i att öppna kontorsmiljöer blivit allt vanligare bland organisationer. Samtidigt ställer den konkurrenskraftiga marknaden nya krav på att organisationer ständigt ska utvecklas och erbjuder nya kreativa lösningar. Det uppmärksammades en tvetydighet i forskningen om huruvida kontorsmiljön kan gy
The importance of sterilization processes has been a major topic in the food manufacturing industry since it preserves the quality and provides longer shelf-life by preventing microbiological recontamination of products. Aseptic packaging is an alternative technique to pack commercially sterile products into containers with a very low recontamination rate, thus, the entire production chain must be
Energiförbrukningen i elektronikprodukter minskar samtidigt som prestandan för solceller hela tiden ökar. Nya solcellstyper med lägre priser skapar nya möjligheter för använding även i små elektronikprodukter. Att samla energi från omgivningen, t.ex. från ljuset i ett rum, och använda det för att driva små elektronikprodukter kallas i ett vidare begrepp för ”energy harvesting” (SV: energiskördningThe power consumption of electronic devices is decreasing at the same time as the performance of solar cells is increasing. Solar cells based on new technologies with lower costs are becoming commercially available, creating new opportunities for use in small electronic products. The concept of capturing ambient energy, such as light, and using it to power small electronic devices is known as ener
This thesis explores the possibility of redesigning ASSA ABLOY’s industrial door in order to improve sustainability through the use of new materials. The first step of the process involved investigating different parts contained within the door, in order to decide which part of the door should be redesigned. Because of its high environmental impact as well as opportunities for improvement, it was
