During high speed machining of titanium alloys both the tool and workpiece material diffuse into one another affecting the surface integrity of the cutting tool edge and leading to fracture. One proposed mechanism by which the tool integrity is compromised results from the possible formation of porosity in to subsurface of the tool substrate close to the tool cutting edge. In this study the porosi
With the popularization and development of CV technology, the SLAM algorithm is widely used in scenarios such as self-driving cars and autonomous navigation robots. As a key step in the SLAM system, the BA algorithm is responsible for optimizing camera parameters and 3D point coordinates. BA obtains more accurate estimates by shrinking the re-projection error. So as to support the SLAM system
This paper focuses on the detection of structural breaks in the second-order matrices of multivariate time series. A comprehensive simulation-based comparison is conducted to measure the performance of three widely cited nonparametric methods that allow for serial dependence in the data: the pure CUSUM procedure with binary segmentation in Aue et al., (2009), the CUSUM-based sparsified binary segm
Agile working methods gain in popularity among practitioners within the IT (Information Technology) industry and beyond, as a result of the revival of the self-organizing team as a mode for organizing work in contemporary organizations. The talk of DevOps, as an agile method which merges opposite organizational logics, IT Development (Dev) and IT Operations (Ops), into a self-organizing team, has

The aim of this thesis was to investigate how packages, both primary and secondary, behave under transportation. Before a full analysis of a pallet distribution can be fully understood the understanding of the separate packages is required. This thesis contributes with great knowledge and understanding of how a primary and secondary package behaves during top load compression. Tetra Pak is a globa
This thesis aims to examine whether archive pedagogy is a useful learning resource in school today, and if so, how this cooperation works in reality. We want to find out how the archive's educational resources are perceived by teachers and students, and where the possible obstacles may lay. By examining how teachers and students perceive the archive education, our study can contribute to bette
Service user involvement has become an important part of social work in Sweden. Social services in Helsingborg has taken a step further in involving service users by including them in the recruitment process of some of their own staff members. Few studies regarding this particular phenomenon has been found thus the need of exploring it further. The aim of this thesis is to explore social workers o
The goal and ambition of this thesis has been to investigate a topic that could lead to a possible solution to the environmental crisis we are witnesses of. Replacement of fossil fuels is an essential step towards a renewable society that needs to be taken. This thesis will investigate one of those possible solutions, production of a biofuel from a renewable source. A large amount of research with
Sustainability philosophers claim that we are at the impasse of stories, finding ourselves in a blank chapter between the old and the new. The old story, characterized by separation, technological arrogance and human superiority over nature, is unfolding in an ecological crisis giving space for a new narrative defined by inter being, cooperation and balance. It has been put forward that this crisi
Chilli extract is used in the food industry for multiple applications, such as a flavour for hot sauces or spicy chocolates. The demand for organic products has grown in the recent years, while changes in demography make it necessary to obtain and aroma that can fulfil the market needs. Hence, the purpose of this project was to develop an extraction method to obtain an organic and halal chilli ext
The Aina project focuses on exploring how design can contribute to the shift towards a more sustainable circular economic system. Aina presents an alternative system for future clothing, where garments are designed to have an extended lifespan, both in production and in consumption. The fashion industry embodies the insanity of the neoclassical market system aiming for endless growth through shor
