Victoria Persson Abstract Mussel cultivation is a sustainable type of food production that may help mitigate the nutritional needs of a future world population of 10-12 billion in 2100. The demand for mussels on the French market is increasing but the production is saturated due to a lack of space for expanding the cultivation close to shore. This study looked at offshore possibilities for cult
In this thesis a concept for a new leg construction, for a force regulated Stewart Platform called Hexapod, was created. The design process for this concept was split into three major parts: the actuator, joints, and the frameless motor, which make up the dynamic elements, the legs, that move the Hexapod. The design of these three parts was approached in a similar fashion, through four phases. T
In the days of IoT and smart homes Bluetooth is in constant development and with it the products that use Bluetooth. Bluetooth mesh is the latest feature and with it comes many opportunities of new products. This report describes the development of an outdoor light system which can be controlled from a website. The system is named Luminaire and consists of a custom built circuit board, an encapsul
The feasibility of implementing a hydraulic load-holding solution in a BorgWarner all-wheel-drive (AWD) coupling was investigated in this work. There exist many sophisticated valve designs intended for load holding applications, but this work focused on simple solenoid valves to reduce cost and complexity. To evaluate the feasibility of the intended load-holding solution, a leakage and pressure dr
Thesis Purpose: This study aims to test whether electronic word-of-mouth in the form of comments on twitter are representative of overall word-of-mouth. The relationship between marketing, twitter comments, sales is tested and compared to word-of-mouth theory and previous studies. Methodology: A combination of cross-sectional research and case study research methodologies were used to understand T
The obligation to use a registered trade mark stipulated in trade mark law exists almost in every jurisdiction. It states that once a trade mark has been registered, the owner must show within several years that the mark has been put into genuine use in respect of the goods or services for which it has been registered. However, the interpretation of the term ‘genuine use’ is vague and it is unclea
This paper describes the development of software that generates graphical icons for classes written in Modelica, an object oriented language for modeling complex systems. The icon rendering is developed as a new feature in the JModelica IDE, a plugin for the multi-language software development environment Eclipse. The JModelica IDE is included in the distribution of the open source project JModeli
This report is the result of a thesis in mechanical engineering focused on product development. The project was performed at MarineDiesel, a company producing diesel engines for marine applications in Ängelholm, Sweden. A need of a sterndrive strong enough for large diesel engines is present on the market. This thesis involves hydraulic systems and mechanical geometry for trimming and steering of
This Master’s Thesis shows how to model the kinematics and forward dynamics for the parallel kinematic robot from ABB, IRB340 FlexPicker, and how to implement the control using software and hardware from B&R Automation. With conventional methods the forward kinematics, inverse kinematics and the kinematics for the velocities and accelerations of the robot are modelled. The forward dynamics, ca
The coalescence of emulsion droplets during the homogenization process is governed by the emulsifier adsorption rate. This is in turn affected by the size and shape of the adsorbing molecule which can be dependant of the aggregation states. The aim of this thesis was to develop a model system suitable for measuring the efficiency of emulsifier during homogenization and to evaluate the hypothesis t
This thesis examines the Oesch class schema in a Swedish context, and tests its ability to unveil cleavages in political preferences. The Oesch class schema operationalizes class by profession. It adds horizontal divisions based on different work logics to the vertical divisions which schemata such as ESEC build on. Two cleavages are thus captured, an economic (left-right) and a sociocultural (lib
Abstract Many species have genetic sex determination and sex chromosomes that differ in size between males and females. This heteromorphy in sex chromosomes has evolved due to the suppression of recombination between Y and X (or Z and W in birds) following the accumulation of sex-specific alleles near sex-determining loci. The degree of gene expression imbalance between the sexes and also relati
Popular Science Summary Synthesis and Reactivity of (PCNMe) Pincer Pd(II) Complexes Cross coupling reactions are considered one of the most important in the field of organic chemistry where C-C and C-X (X= Heteroatom) bonds easy to form in presence of catalyst. These reactions have been employed to synthesize different types of drugs, polymers and agricultural chemicals. Palladium complexes were
In our research paper, we shed light on the various impacts of acculturation and changes in religious consumption in the lives of muslims, who have migrated from the east and are experiencing life in the west. We took into consideration the holy month Ramadan as a religious reference to our study where we examine muslims religious performance during this time. As Ramadan is considered the most spi
Purpose: The thesis aims to address the different roles incumbent firms can take in the emerging plant-based ecosystem and to contribute with new understandings related to these ecosystems. Theoretical framework: The theoretical foundation for the thesis is rooted in theories on systems thinking, ecosystems and with a discussion around the roles that are inherent in ecosystems. This is accompanie
