Degradation of tools is a prevalent aspect in the mechanical world; due to the advancement of technologies and intense research and development, there are new ways and ideas to curb or delay the tool failures; one such idea is to implement Metal Matrix Composites (MMCs) with various reinforcement materials. This thesis focuses on improving the hardness and wear resistance of Hadfield steel b

Intelligent reflective surfaces (IRS) are envisioned to have a significant number of applications in future wireless network systems by reconfiguring the signal propagation to improve system performance. In particular, the IRS's cell elements can independently reflect the incident signal by tuning its phase and achieving passive beamforming to enhance the received signal of the user equipment.

The Missing Middle describes a phenomenon and a movement to fill a gap in the housing choices offered in many North American cities. Although proponents of the movement state that Missing Middle forms can seamlessly replace single-family housing in existing neighbourhoods, a paradigm shift in Vancouver’s housing supply presents an opportunity to restructure its public spaces and services in tandem

Thesis purpose: The purpose of our research is to examine the intersection of organisational change and the corporate brand identity in the hybrid workplace model. We explore the implications of the model on the corporate brand identity, how brand identity may be shaped in the model and the reasons why identity may change during the hybrid workplace model transformation. Theoretical perspective:

This qualitative mixed methods case study aims to seek understanding of employer branding within the public sector from a New Public Management perspective. The chosen case is two campaigns from the Swedish Armed Forces of 2011 and 2019. Due to political changes in Sweden, the Swedish Armed Forces faced major organizational changes regarding their staffing. Through a text analysis of the commer

The study of the impact of social capital on economic outcomes is currently on the rise. Social capital is a multidimensional concept hard to grasp. This paper makes an attempt to comprise such range of dimensions and analyzes its impact in a potential channel for growth, financial development. Three rural-based provinces of Vietnam are the places where this analysis takes upon. Vietnamese society

Equity crowdfunding has achieved a high popularity in the UK throughout the last years. However, most researchers within this field primarily focused on the success factors of an equity crowdfunding campaign while only little is known about the post-campaign effects. Therefore, the aim of this thesis is to determine which patterns of characteristics successfully equity crowdfunded companies that r

The conflict mineral crisis has been ongoing in the DRC for nearly two decades, with armed groups and increased military presence have played on the tin, tantalum, tungsten and gold to fund a brutal war across the eastern region of the country. Recent international efforts to tackle such illicit trade in conflict minerals has focused on requiring relevant stakeholders involved in the mineral sourc

In 2019, migrant seasonal workers from outside the EU constituted approximately twenty percent of the hired workforce within the agricultural sector in Sweden. However, the total share of migrant seasonal workers is assumed to be even greater. During 2020 this figure dropped significantly due to the travel restrictions associated with the COVID-19 pandemic. According to the Federations of Swedish

This paper examines the reaction of the U.S. stock market to various economic conditions over the last two decades. The major finding reveals a substantial difference between the two subsamples segmented at the decade node. The presence of a moderating effect is highly significant only in subsample 1. The fitting evidence from GJR-GARCH is mixed. In the case of subsample 1, the significance of the

Sustainability transformations will require a fundamental re-thinking of work. However, so far the role of reproductive care work in these transformations is hardly recognized, although this work is low-carbon and essential in sustainable futures. This thesis examines the intersectional coalition politics articulated by feminist activists, climate justice movements and labor unions around the role

The aim of the study was to investigate how municipal home care workers can determine whether an elderly woman in an ordinary home has been or is being subjected to violence, of any kind, by her partner, and how the home care workers respond to their findings. My two key questions were: how do staff detect that an elderly woman is being or has been subjected to some form of violence by her partner

As cities get denser due to urbanization, the importance of competitive public transport increases. Since a central factor when choosing transport mode is travelling time, high speeds and short delays are essential to attract more travellers to public transport. Many cities around the world, including Sweden, have implemented Bus Rapid Transit (BRT) or bus lines inspired by BRT, to make travelling

Magnesium corrosion in an aqueous environment is a multi-layer, complex process. A literature survey shows significant gaps and the modelling work reported indicates a lack of clarity in understanding the corrosion process. Studies on the effects of impurities and interfacial compounds formed by selected alloying additions would help in filling some of these gaps. Further, the evolution of hydro

Trots att distansledarskap inte är något nytt så föranledde utbrottet av covid-19 en snabb omställning från ett arbete där medarbetare träffades fysiskt, till att på kort tid lära sig fungera på distans. Syftet med studien är att undersöka de utmaningar som ledare har erfarit under omställningen till distansledarskap, och på vilka sätt de har försökt lösa dem. Ur den tidigare forskningen har återk

The change of color of water from yellow to brown termed as brownification process is mainly due to leaching of humus and iron concentrations. In recent years, this problem is increasing in lake Bolmen, a major source of drinking water in Skåne county, Sweden. This process has been a threat to aquatic life and increasing the water treatment cost too. Storån river being the main tributary of the la

Studien syftar till att ta fram rekommendationer och råd kring hur klimatpåverkan från anläggningsentreprenader kan beräknas och redovisas. Detta genom att undersöka hur andra aktörer inom branschen agerar i frågan och kartlägga modeller och verktyg för klimatberäkningar. Studien har utförts som en kombination av kvalitativa och kvantitativa forskningsmetoder, vilket kan liknas vid begreppet triaThe purpose of the study is to come up with recommendations and advice on how to calculate and present the climate impact from construction works. This will be implemented by examining how other actors within the construction industry is acting on the issue and examine models and tools for climate calculations. The study was conducted as a combination of qualitative and quantitative research meth

Vår studie undersöker hur värdesamskapande och förväntningar både uppstår och hanteras i en hotellkontext. Genom intervjuer och dokumentanalyser granskar studien varför dessa processer ser ut som de gör. Vi kommer fram till att hotells hantering av gästers förväntningar och utveckling av värdeerbjudanden är en gissningslek. Eftersom forskningsläget på området är skralt och då relevant litteratur e

In May 2020 the Land and Environment Court concluded that Vellinge municipality are granted the right to build a total of 21 kilometers of walls and embankments for protection against a rising sea water level. To analyse this problem an Extreme Value approach is applied to sea level data from the area. Both Block Maxima and Peaks over Threshold models are fitted and return levels are calculated.
