The generalized minimal residual method (GMRES) is an iterative method used to find numerical solutions to non-symmetric linear systems of equations. The method relies on constructing an orthonormal basis of the Krylov space and is thus vulnerable to an imperfect basis caused by computational errors. There have been attempts to address this issue by devising variations of the method that are less
This report is the result of a master thesis project conducted at the Global R&D Dish Care Department at Electrolux, Stockholm. The master thesis has been carried out through the Division of Machine Design, Department of Design Sciences at the Faculty of Engineering (LTH), Lund University. Electrolux is a developer and producer of household appliances active on the global market. Their focus
In this study I address the issue of sustainable food production through the concept of Industrial Symbiosis (IS). Food production constitutes a key driver of environmental degradation and is prospected to accelerate its impacts with a constantly growing world population. Unsustainable and inefficient resource and energy use in the production sector further intensifies these problems. Through stud
Syftet med uppsatsen är att undersöka relationen och gränsen mellan människa och djur i Per Odenstens Andningskonstnären (2013) och att studera djuren funktion i romanen. Metoden som används är en läsning av Andningskonstnären utifrån ett "animal studies"-perspektiv. I huvudsak tillämpas teoretiska begrepp från Giorgio Agamben, som antropocentrism, den antropologiska maskinen, antropomor
Regulation of aviation has entered into a deliberate and noticeably movement away from purely compliance-based regulation towards performance-based regulation, by which the providers and operators are required to reach a certain level of performance, while being granted a larger degree of freedom to choose the methods to achieve their target. Hence the focus of the entire aviation community is shi
Palpable computing is a new research topic that has been developed to solve some of the issues found with the original way of looking at pervasive computing. The research into this topic has, among other things, resulted in a middleware called PalCom. The purpose of this thesis is to evaluate how well PalCom fits as an IoT platform by comparing it to an existing system made with PHP (recursive acr
In the state of Acre, Brazil, there is ongoing land use change, where inhabitants of this part of the Amazonian rainforest practice shifting agriculture. Practicing this type of agriculture is, according to the SKY Rainforest Rescue organization, damaging to forest ecosystems. This organization aims to educate people in how to maintain sustainable agriculture. By monitoring this shift in agricultu
The automotive industry is in for significant changes in the years to come. With the acknowledgment of greenhouse gases as a major contribution to global temperature rise, energy usage sees a transition in favor of renewable sources. Adding the uncertainty of whether a peak-oil production is reached or not, fossil fuels are no longer considered reliable. In the wake of this, new candidates emerge
Denna uppsats undersöker hur individer från två åldersgrupper resonerar vid beslutsfattande för att se vilka likheter och skillnader det finns mellan dessa. Även vilka sociala faktorer som kan förklara dessa har vi studerat. Nio intervjupersoner, varav fyra personer i den yngre och fem personer i den äldre åldersgruppen deltog i studien, där semistrukturerade intervjuer användes som undersökningsm
The purpose of this project was to investigate the possibility to create 3D printed implants intended for bone healing studies in small animals at the Biomechanics group at Lund University. The aim was to use cheaper but stable non metallic implants and find out what printers and materials are suitable and accessible today. An Ultimaker 2 was used to produce both nails and screws in Polyhydroxyalk
Denna uppsats handlar om hur sociala medier påverkar anställda och därigenom företaget. Många branscher idag, som till exempel inom servicebranschen, använder sociala medier som verktyg för marknadsföring och för att kommunicera med kunderna. Utöver detta använder en del företag sociala medier internt bland anställda. De sociala strukturerna och miljöerna har tagit nya former med implementeringen
A novel method for the fabrication of a light-weight solid oxide fuel cell (SOFC) has been evaluated at Catator. This was conducted in order to lower the weight and thus cost of an unmanned aerial vehicle. The main aim for this thesis was to achieve a thin, dense and crack-free electrolyte using a ceramic fibre paper as substrate. This paper was impregnated with colloidal solutions and pressed to
Det är fascinerande att fundera över hur den antika människan förstod kroppen och i synnerhet kopplingen mellan känslor och kroppen. I syfte att förstå det bättre har jag i den här uppsatsen studerat hur Vergilius använder medicinska, fysiologiska eller anatomiska termer för att beskriva känslor och psykologiska tillstånd. Jag har också studerat vad som är den metaforiska betydelsen av dessa begreIt is fascinating to think on how antiquity pictured the human body and especially the connection between the mind and body. To better understand this I have studied how Virgil uses medical, anatomical, and physiological terminology to describe feelings and psychological phenomena. Furher, I have studied the metaphoric value of this terminology and sought for explanations in differences between Vi
Sjuksköterskeyrket är ett mångfacetterat arbete som kräver och stimulerar till livslångt lärande. Vården som bedrivs idag är i ständig, pågående förändring med nya behandlingar, högteknologiska tekniker och ett arbete i komplexa vårdmiljöer. Ett kontinuerligt lärande är väsentligt för att upprätthålla kompetensen. Syftet med litteraturstudien var att belysa faktorer som påverkar sjuksköterskans lä
Functional food (FF) is a relatively new sector in the food industry. FF are products that have an added nutritional value for consumers that is communicated through nutritional and health claims, and act as preventive agents of chronic diseases. Innovation of new FF products has grown to become an important impact in research towards preventing welfare diseases. The rate of innovation in this fie
I denna studie undersöker jag hur några studerande inom miljövetenskap, hanterar den problematik som råder mellan att försöka vara miljövänlig och upplevelser av de krav och begränsningar som innebär att leva i ett konsumtionsinriktat samhälle. Intresset ligger i att skapa en förståelse för hur denna problematik uppfattas av intervjupersonerna på en individnivå. Med hjälp av intervjuer undersöks d
The Vision Zero was initiated in 1997 with the aim that no loss of life or seriously injured are acceptable in the transportation system. To improve the traffic safety the National road administration in Sweden, Trafikverket, has defined two areas with considerable potential to change the traffic safety situation and reduce number of people killed in traffic. These are lower “average speed” and hi
