Co-simulation is widely used in industry for the simulation of multi-domain linear-time-invariant systems. However, as a result of the not continuous communication between our coupling variables, simulation results end up being unstable and inaccurate. Among the different strategies that have been developed in the recent years to control co-simulation drawbacks, the aim of this thesis is to unders
This thesis creates multiple indices to score and rank developing countries with regard to their suitability for engaging in debt-for-climate swaps, and thus identify the most suitable country candidates. The origin of debt-for-climate swaps lies in the 1980s, and after a period of diminished use and attention they have become a topic of discussion again, especially in the last two years. Desp
Payment and bonus schemes based on seed quality used by the Swedish agriculture cooperative Lantmännen is evaluated. Results from a farm and region/time fixed effect model show that the linear payment scheme for pulses (peas and beans) has approximately 15 percentage points lower quality compared to that used for grains when a common quality measure constructed for this research is used. Germinati
Sammanfattning Digitala övervakningskameror har tidigare använts inom fenologisk forskning för att kunna mäta grönskan i trädkronor. Man har under en längre tid kunnat koppla lövträdets årscykel till klimatförändringar och på så sätt haft ett starkt incitament att studera sambandet. I denna uppsats utforskas möjligheten att applicera metoden med digitalkameror på ett nyligen kalhugget område för aAbstract The use of inexpensive digital cameras in phenological research has been acclaimed since results in previous research have shown that they are reliable and precise in measuring greenness of vegetation. The work of this thesis aims to broaden the applicability by studying how well the method performs when measuring the regrowth of a clear-cut area. This is needed to complement existing res
The advantages with infrared heating and the fact that the technology has become significantly more inexpensive opens up a bigger interest to develop products using infrared heaters further. What will the future kitchen look like? How can infrared technology develop and create more conventional and intellectual products processing our food? By pushing the limits of the technology today the main
This thesis investigates the stock return and its variance around seasoned equity offering announcements for Swedish companies listed on the OMX Large cap, Mid cap and Small cap exchanges. The analysis is made on a full sample containing 52 SEOs, as well as two sub-samples containing underwritten and non-underwritten SEOs. The framework for the event study is OLS regressions based on the CAPM-mode
As the spread of the internet continues, more people than ever search for medical information online when in need of health advice. Color is a prominent part of website aesthetics, and has been shown in the literature to have both positive and negative psychological effects. A total of 120 participants took part in the present study where the effect of the colors grey, blue, orange and red was tes
Popular science summary: Potential Distribution for the Endangered Asian Wild Ass Over the past century, large mammals have been globally under increasing pressure of humanized landscapes. Since extirpations of large herbivores are likely to have complicated consequences for the entire ecosystem, their conservation is a priority. With almost 81% threatened species, Perissodactyla (odd-toad ungu
The debate about the link between economic growth and foreign trade is still open amongst scholars. There exist four main hypotheses regarding the relation between imports, exports and economic growth. The first one states that growth can come only through increasing the volume of exports of the country, i.e. export – led – growth hypothesis. The second one (growth – led – exports hypothesis)
The Magoye River is located in the Southern Province of Zambia. This is the most drought prone region in Zambia and a lot of water bodies dry up during the dry seasons, including the Magoye River. Small scale livestock farming is widespread in the area and low water availability during dry seasons forces local farmers to push their cattle long distances for drinking water and grazing during dry se
Bröstcancer är den vanligaste formen av cancer hos kvinnor. Fler än 7000 diagnostiseras med denna sjukdom varje år i Sverige. En del av behandlingen mot cancern är strålbehandling. För att strålbehandlingen ska ge goda effekter är det viktigt att det är den sjuka vävnaden som bestrålas, och att den friska vävnaden förskonas från strålningen i den mån det är möjligt. Detta uppnås genom noggranna stPurpose: The CatalystTM system was tested and compared with an X-ray image verification system for patient positioning during breast cancer treatment. Included was to find the optimal reference image and the optimal cropping method for the reference image. Parameters that could lead to an optimization of the treatment routines were also evaluated. Method and Material: The study was divided into t
The T cell receptor (TCR) initiates the elimination of pathogens and tumors by T cells. To avoid damage to the host, the receptor must be capable of discriminating between wild-type and mutated self and nonself peptide ligands presented by host cells. Exactly how the TCR does this is unknown. In resting T cells, the TCR is largely unphosphorylated due to the dominance of phosphatases over the kina
Modal choice is a prominent concept within transport studies. However, the term is often used quite loosely, with little known about the factors lying behind the choice, the alternatives available to a person, and whether the person had a ‘choice’ to begin with. This study draws on a travel survey among older people living in Sweden’s large metropolitan regions. The questions posed as part of this
Lean Startup has been impacting how startups and incumbents innovate their business models. However, academic understanding of Lean Startup and the associated experimentation process is only emerging. Recent academic critique of Lean Startup by Felin and colleagues (in press) highlights the inadequate guidance provided for hypotheses generation; limits of experiential learning from customer feedba
In the present paper, linear substructures with nonlinearities localized at their interfaces, such as the joints in a beam structure, are studied. By subdivision of the total structure into substructures, reduced subsystems are obtained by component mode synthesis. Nonlinear elements are introduced at supports or between substructures. A numerical example is presented where a beam subjected to bla
Deficiency of ornithine-δ-aminotransferase (OAT) in humans results in gyrate atrophy. Early diagnosis may allow initiation of treatment before irreversible damage has occurred. However, diagnosis is commonly delayed well into adulthood because of the nonspecific character of initial symptoms. Here, we report findings in a neonate who was evaluated because of a positive family history of OAT defici
Event-based sampling has been proposed as a general technique for lowering the average communication rate, energy consumption and computational burden in remote state estimation. However, the design of the event trigger is critical for good performance. In this paper, we study the combination of innovation-based triggering and state estimation of nonlinear dynamical systems using the particle filt
Background: OncoMasTR is a new multigene prognostic test that was discovered via a novel transcriptional network analysis method that identified upstream Master Transcription Regulators (MTRs), which regulate previously identified prognostic biomarkers. The optimised OncoMasTR signature incorporating clinicopathological information has been shown to be significantly prognostic for predicting dista
Vehicle-to-vehicle (V2V) wireless communications can improve traffic safety at road intersections and enable congestion avoidance. However, detailed knowledge about the wireless propagation channel is needed for the development and realistic assessment of V2V communication systems. We present a novel geometry-based stochastic MIMO channel model with support for frequencies in the band of 5.2-6.2 G
