Topologioptimering är ett populärt och effektivt verktyg för att hitta smarta designer utformade för att fungera optimalt. Det aktuella forksningsarbetet presenterar en metod för att kunna optimera strukturer som utsätts för varierande laster där det inte är uppenbart var, eller när de högsta spänningarna kommer uppstå. Detta innebär att robusta strukturer smidigt kan genereras som kommer hålla föStress is a key component for structural designs in a variety of applications. The aim of this work is to obtain mechanical structures that are free of stress concentrations. A common ap- proach is to optimize a structure with respect to a specific load case. However, if the structure is subjected to other load cases than the one it has been optimized for, it may not withstand those loads. Also, i

The textile product industry has many challenges and all designers creating products using textiles will have an impact on the environmental sustainability in the world. The project investigates state of the art textile product design today, the challenges of environmental sustainability in the future and how the designer plays a role in making a positive difference. Qualitative research was done

Lithium ion batteries enable the implementation of renewable energy and electric vehicles, both of which are crucial for the transition to a sustainable society. Due to environmental, economic and political reasons, these batteries must be recycled efficiently. Most lithium ion batteries are placed on the market in electric vehicles, which are reaching end-of-life at an exponential pace, prompting

Saltmarshes are areas of coastal grassland that are regularly flooded by seawater. They support a large number of resident and migratory bird species, both overwintering and breeding. The Mersey Estuary Site of Special Scientific Interest (SSSI) is situated in North West England and it supports nationally significant numbers of overwintering wildfowl and waders. Decline of three overwintering bird

Design, as a principal function for innovation in business, governments, and other social units, can play a critical role in creating sustainable solutions. While current debates acknowledge expanding design scope and continuing competencies that distinctively qualify design professionals for undertaking sustainability challenges, design schools in higher education institutions are struggling to m

The use of short range microwave radars for motion sensing purposes are on the rise in multiple industries, as they are accurate, small in size and relatively cheap. The automotive industry, in particular, has pushed the development forward. Lately, the home alarm industry has also been glancing at the technology. Radars are well suited for outdoor applications as they are insensitive to precipita

This thesis represents results from a numerical study of the ventilation system in the control room in the Swedish submarine A26. This thesis's primary focus is to study and examine the performance and efficiency of the current ventilation system. The ventilation system is very critical and crucial in enclosed environments. Many factors and parameters are affected by the installed system. In c

Pillows are an important part of sleeping comfort. The goal of the master thesis was to get a better understanding of pillows for IKEA. To reach that goal, a customer study of 20 customers was performed. Information about and measurements of each customer were collected in order to find a pattern between data and opinions of pillows. Each customer laid on a mattress and tried five different pillow

As a result of the rapid population growth, the increasing economic interests and the global climate crisis, disputes over freshwater resources become more frequent and severe. Although many States pursue environmental cooperation to avoid or resolve water conflicts, such cooperation agreements often suffer from a weak political will to implement just cooperation mechanisms. This is particularly t

In case of a head injury or trauma a surgeon opens up the skull by removing a bone piece of the skull to either relieve pressure or get access to brain tissue. The first option is to follow up with putting back the same skull piece. In the circumstances this is not possible however, a surgeon must open up the skull and form a piece using bone cement that fits the whole during the surgery, which is

This research overall aims to ​investigate the GAP (Southern Eastern Anatolia Project) of Turkey and its approach in the years between 1989 and 2018 by answering the main question:'How can the GAP's(​Southern Eastern Anatolia Project)approach as a developmental state project on women in the region be understood by applying a critical feminist perspective? This question has been examined w

Rotavirus and the Neonate: Memories of infections gone by Despite advances made through vaccination, the disease burden of rotavirus in the developing world remains high, largely affecting children below the age of 5 and remaining the leading cause of death from viral gastroenteritis (Fig. 1).

Considering the lack of progress in regulating unfair corporate

Methane metabolism in the peatland is an important step within global carbon circulation. It is essential to understand the functional composition of the microbial community related to methane metabolism in the peatland ecosystem. In this study, a bioinformatic workflow was built to analyze a capture metagenomic dataset of peatland soil at three depth groups (5cm, 10cm, 15cm) and visualize the fin

Bakgrund: Diabetes är en sjukdom som ökar i hela världen. Följdsjukdomar kan förutses till viss del och sjuksköterskor i vården bör ha kunskap om vilka dessa följdsjukdomar är och hur de kan bemötas. Sexuell dysfunktion är en av dem. Personer med diabetes typ 2 har en ökad risk för att utveckla sexuell dysfunktion. Syfte: Systematiskt granska hur den sexuella dysfunktionen upplevs av personer med
