The Implementation and some mathematical properties of GMRES and weighted GMRES (WGMRES) are described. Numerical experiments originally performed by Essai (1998) are performed to compare the two methods. GMRES and WGMRES are used to solve a linear system arising from the Poisson equation and compared with respect to computational effort.
Tropiska bergmolnskogar (eng: Tropical montane cloud forests; TMCF) är unika ekosystem som frekvent omges av moln vilka ökar fuktigheten och gynnar tillväxt av mossor. Koldynamiken hos mossor påverkas av fukt över flera dimensioner. Det är därför projicerat att klimatförändringen kommer få en stor påverkan på dem samt även på de TMCF. Målet med denna studie var att se hur effekterna av förändrade Tropical montane cloud forests (TMCF) are unique ecosystems that are frequently surrounded by clouds which increase humidity and promote the growth of bryophytes. Several dimensions of humidity are important for the carbon dynamics of bryophytes. Climate change is therefore projected to have a large impact on them as well as on the TMCF itself. The present study aimed to investigate the effects th
In our everyday life we live distant from the origin of life itself - nature. Dramatic landscape and fascinating views touch us in a way that few other things manage to do. It is something that make us recognize our powerlessness and the feeling of awe towards the nature. Experiencing striking nature is a way to create a deeper understanding of our own world and at the same time enrich our lives w
Molnet är ett begrepp som används mer och mer och allt eftersom företagen bekantar sig med de relaterade begreppen och vad de innebär och de tjänster som erbjuds av leverantörerna mognar så vänder sig fler och fler företag till molntjänster för att tillgodose sina behov. I det här examensarbetet undersöks vilka problem man stöter på vid en migrering av en existerande serverlösning samt hur man bäsThe Cloud is becoming a more and more popular expression and as companies learn what it is and the cloud services offered by cloud providers mature, more companies are looking towards The Cloud to satisfy their needs. This master thesis examines issues that can arise when moving an existing server solution to The Cloud and how to utilise the possibilities offered by cloud services with a cost-effe
Today, Swedish police authorities nationwide collect data of traffic accidents. The information is stored in a national database managed by the Swedish Transport Agency and is an important resource in the process of analysing and improving road safety. Literature studies in this thesis, together with earlier work by the author have suggested that the data collection process is in need of an upda
Automatic interpretation of reading from the brain could allow for many interesting applications including movement of prosthetic limbs and more seamless manmachine interaction. This work studied classification of EEG signals used in a study of memory. The goal was to evaluate the performance of the state of the art algorithms. A secondary goal was to try to improve upon the result of a method tha
Hem-ligheter hos Bacillus subtilis För att ett protein eller enzym ska vara funktionellt behöver ibland en mindre molekyl (prostetisk grupp) vara bunden till detta. Hem är en prostetisk grupp som ingår i flera livsnödvändiga proteiner/enzymer i både djur, växter och bakterier. Man hittar hem-grupper t.ex. i vårt blods syrgastransporterande hemoglobin och i enzym som behövs för att celler ska kunn
This paper examines long-term interest rates and fiscal liabilities within EMU in the context of the recent sovereign debt crisis; where Greece, Ireland, Italy, Portugal and Spain faced rising interest rates in contrast to the rest of the EMU. An assessment of the short and long-run properties of long rates, fiscal deficits and government debt are estimated for 11 EMU countries in the time span 19
The informal sector is often seen as one sector with the potentials to transform the economies of developing countries if well harnessed. This is particularly true in the case of Nigeria where the informal sector creates employment opportunity for a large number of the labor force compared to the formal sector economy. However, it is also pertinent to bear in mind that the informal sector is often
This study will investigate and understand the social norms that resides within a globally operating organisation. Within this organisation, this study targeted the Human Resource department for its unique role and close bond to the company policy which can provoke ethical dilemmas that require a collective understanding among the employees and managers to resolve. The Krupka-Weber method is appli
In this thesis, we study the Jarrow and Yildirim framework for inflation modeling and provide a new specification based on spread modeling which allows to calibrate the model to Zero-Coupons and Year-on-Year options jointly with convexity adjustments. We use this model to provide closedform formulas for options volatilities, convexity adjustments and Year-on-Year swaptions prices. Calibration resu
The Compact Linear Collider (CLIC), is one of the proposed successors to the Large Hadron Collider (LHC) accelerator at the European Organization for Nuclear Research. (CERN). In CLIC, particles are accelerated by very strong electric fields. Unfortunately, large electric fields may lead to vacuum discharges, which in turn can affect the particle beam by disrupting the flow of energy inside the ac
In order to alleviate the financial burden on the healthcare sector as well as relax its employees’ workload, there is a need to introduce novel tools that automate some of the tasks that today are performed manually. Especially pathology poses a problem with few pathologists, demanding manual labour and unnecessary work on benign tissue. As a response, the DOGS project aims to develop a tool to a
Under de senaste åren har uppmärksamheten kring Corporate Social Responsibility (CSR) utvecklats (Grankvist, 2009) i enlighet med den ökade köpintentionen för etiska attribut som konsumenter uttrycker (Becker-Olsen et al, 2006; Lee et al, 2010, 2005; Mai, 2014). Forskare har funnit att den höga köpintentionen (avsikten att köpa) för etiska attribut återspeglas inte i det faktiska köpbeteendet (utfCorporate Social Responsibility (CSR) has been gaining more attention in recent years (Grankvist, 2009) as consumers have indicated a strong support intention for ethical attributes (Becker-Olsen et al, 2006; Lee et al, 2010, 2005; Mai, 2014). Researchers have found that this support intention does not imply a strong correlation to purchase behavior (Carrigan and Attalla, 2001). In fact, the purch
The Greater Cairo is one of the most crowded cities in the world and it is the biggest metropolitan area in Middle East. The high population density in the Greater Cairo causes traffic problems that harm many living aspects. This study discusses one of the solutions for limiting the traffic congestions using bicycle as an alternative transportation mean which is already applied in many other count
ISO 14001 är en internationell miljöcertifiering för företag som vill arbeta mer effektivt med sina miljöpåverkande aspekter. Även om det inte går att fastställa att ISO 14001-certifierade företag faktiskt minskar sin miljöpåverkan, visar tidigare studier att certifierade företag uppfyller miljölagkrav bättre än icke-certifierade företag. Ett av kraven som ställs på företag när de certifieras är aEven though there is little evidence that ISO 14001 certified companies actually reduce their environmental impact, previous studies show that certified companies comply to environmental regulatory demands better than non-certified companies. The purpose of this study is to examine the regulatory compliance of ISO 14001 certified companies in the south of Sweden. The empirical data is based on ins
Ett av mina starkaste minnen kring arkitektur är minnet ä av en pojke som cyklar på en trehjuling Han trampar snabbt på tramporna och far fram genom korridorerna inne på hotellet där han bor. Dörrarna in till hotellrummen på vardera sidan om honom svischar snabbt förbi. Trehjulingens däck låter dämpat mot den mjuka mattan på golvet när pojken cyklar om hörn efter hörn innan han plötsligt stannar fOne of my strongest memories concerning architecture is the memory of a boy, riding his tricycle. He’s pedaling fast. He’s shooting through the corridors of the hotel where he’s living with his mom and dad. The doors to the hotel rooms on either side of him pass by in a fast pace. The wheels of the tricycle make muffled sounds against the soft carpets on the floor as the boy rides passed one corne
Artbildning genom hybridisering mellan blåhallon, Rubus caesius (Rosaceae), och björnbär inom Rubus sect. Corylifolii Jag har undersökt huruvida hybridisering mellan olika arter av krypbjörnbär, Rubus sect. Corylifolii, och blåhallon, R. caesius, kan leda till bildning av nya självständiga arter. För att kunna avgöra detta har jag tagit fram data från nukleära mikrosatelliter och jämfört vilka alWe have studied the genetic relations among blackberries, Rubus sect. Corylifolii, and dewberries, R. caesius, by comparing presumed hybrids with their parental taxa. To be able to determine the status of the hybrids we have observed absence or presence of nuclear microsatellite alleles in electrophoresis, and calculated the different relative genetic distances between the relevant taxa.
