There are several methods avaliable to find areas of interest, but most fail at detecting such areas in cluttered scenes. In this paper two methods will be presented and tested in a qualitative perspective. The first is the darg operator, which is used to detect three dimensional convex or concave objects by calculating the derivative of the argument of the gradient in one direction of four rotated versions. The four versions are thereafter added together in their original orientation. A multi scale version is recommended to avoid the problem that the standard deviation of the Gaussians, combined with the derivatives, controls the scale of the object, which is detected.

Studies of networks, fields and of communicative circulations complement each other. This master thesis is a biographical study of an author and journalist, Gustaf Montgomery GM, his network in Sweden of the early 19th century, and a study of his authorship and literary career. The starting-point of the study is GM:s change of field from the conservative to the liberal in 1832. The aim is to give explanations to this change and to describe how the change in turn effected the network. The method used is critical of sources.

In the early morning of February 24th, 2022, Russian troops crossed the border to Ukraine which started the full-scale war between Ukraine and Russia. Even though the war does not directly involve the EU or member states of the union, it affects the lives of the European people. While previous research has established that general attitudes towards the European Union and European integration has changed in some countries within the Union since the start of the war, the question remains how attitudes towards EU and European integration has changed across EU. A second unanswered question is whether populations in Western and Eastern Europe have responded differently, leading to a potential divergence or convergence in attitudes. The theory ?Rally around the flag? suggests that an outright war that border to EU will increase support for the political leadership in EU.

Det finns många faktorer som påverkar kvaliteten på styrelsens arbete. Tidigare forskning har funnit ett negativt samband mellan värdering av företag och antal styrelsemedlemmar. Då det finns en avsaknad av liknande studier på den svenska marknaden avser denna studie att undersöka sambandet mellan styrelsestorlek och värdering av företag. Vi undersöker 203 bolag noterade på Nasdaq OMX Nordic under perioden 2011-2013 med hjälp av en regressionsanalys. I motsättning till majoriteten av tidigare forskning finner vi ett positivt samband mellan styrelsestorlek och värdering, mätt som Tobin?s Q, för företag listade på Nasdaq OMX Small Cap.

Wind and wind damage has become a hot subject because of the storm ?Gudrun? in January 2005. The main purpose of this study was to establish how the land owners attitude toward preventive wind damage actions was changing immediately after they had been struck by a storm. The result of the study was built on interviews. In springtime 2005 a total number of 20 private land owners were interviewed. Ten of the landowners lived in the province of Småland and ten in the province of Värmland.

The interest in small-scale electricity in Sweden has increased strongly in recent years. The interest is noticeable both among politicians to increase the share of renewables in the energy mix, and among electricity consumers to partially replace purchased electricity with self-produced. This has resulted in a significant increase of electricity production in low voltage grids in recent years, and the trend appears to continue in the coming years. The majority of the new production plants are solar cells, followed by wind turbines, and it is also in these the greatest efforts are made in this paper.Distributed generation is often seen as something positive since it will contribute to reduced transmission losses and reduced voltage drop in the networks, and that it increases the share of electricity from renewable sources. In cases where the grids are not strong enough, or in other ways not adapted to manage the installed production, power quality may be adversely affected.

Syftet med aktuell studie har varit att på svenska akademifotbollsspelare undersöka (1) självbestämmande motivations samt passions inverkan på upplevd hälsa och hur dessa variabler är relaterade till varandra, (2) samt skillnad i upplevd hälsa mellan högt harmoniskt passionerade spelare och spelare med hög tvångsmässig passion. I studien deltog 462 akademifotbollsspelare hemmahörande i Svenska fotbollsakademier. Deltagarnas ålder varierade mellan 12-16 år (M=14.38, Sd=1.06). I studien användes instrumenten Self-Determination Scale (SDS), The Passion Scale samt General Health Questionnaire-12 (GHQ-12). Korrelationstester i rådande studie visade på att självbestämmande motivation har ett positivt samband med både tvångsmässig och harmonisk passion, samt att tvångsmässig passion har ett negativt samband med hälsa.

We have during these three past years been getting formal knowledge in business economics and believe that, now in the end of our education, we are qualified to the demands that are put on the labour market. The purpose of this report has been to write about, such an extensive subject area as public purchase though we feel the education is lacking this area and have therefore decided to do our dissertation in public purchase.Due to lack of time we have not been able to investigate in the extent we wanted, we had to delimit in sort of municipality and purchase product. We have been investigating in how the process of purchase of aid in Malmö municipality approaches because we wanted to enter deeply into those studies.This rapport represents the process of public purchases of aid from both the suppliers point of view as well as the purchase units. All the steps in the process are presented in our investigation.By writing this rapport we have presented the division of responsibility of aid, it is divided between Region Skåne and the municipality in Skåne. In Malmö the responsibility is divided between two activities, one of them is Hjälpmedelcentrum who is responsible of the municipality part and the other is Hjälpmedel Malmö who.s responsible of the regional part.We have decided to investigate only on the municipality part of the responsibility division and have gradually found out that they in Hjälpmedelcentrum reuse their aids after them being returned from the needed ones in the municipality or even after that the need has stopped, the unit can by reuse save on new purchases.In the end of writing this rapport we noticed that owners of small businesses have a difficult time of getting in the market of public purchase.

In Europe poplar plantations has been planted for more than one hundred years. In the first plantation was made in 1940. The interest for poplars has since then shifted over the years and has for long periods been very low but is now slowly increasing again. The main reasons why poplars are becoming more interesting are because of their great production potential. Nevertheless, the knowledge of how to mange poplars in Sweden are very low and very little research has been done concerning management of the species. The objective for this study was to; 1) investigate and document experience and results obtained in practical Swedish forestry, 2) to give a fair picture of the perceived advantages and disadvantages that the poplars has for the forestry, 3) document what the foresters that has experience and those who has no experience of poplar plantations thinks about the potential of poplars.

Smallholder farmers in Uganda suffer from declining productivity. With a rapidly increasing population, marginal land is taken into production and the current land management leads to loss in soil fertility and escalation in soil erosion. There are studies indicating that the use of agroforestry increases soil organic carbon (SOC) compared to systems without trees. Soils which are high in carbon have many advantages, for example better water holding capacity, which can reduce stress on crops during drought. The aim of this study was to determine the effect agroforestry has on SOC concentration in small-holder farming systems in Uganda. The intended system to study was farms practicing agroforestry methods or not in intercropped plantain (cooking banana) fields.

The aim of thesis was to, through a action research study and through individual interviews with five students, clarify their perspective on educational assistance in high school. The study shows that students prefer teaching in small groups outside of regular whole class because it gives the them access to the factors they consider crucial for a functioning support-time whit a skilled and dedicated teatcher, in a calm and safe environment. Moreover, the students claim the importance of technical equipment especially in the Swedish subject, but also in other subjects. Today the educational assistance varies from an outside-the-class teaching situation to a whole-class situation with teacher support as well as technicaal equipment. When the student were asked to describe the cinditions under which studies can be conducted with the whole class they tried to imitate the learning environment they have in a small group.

To achieve the requirements to decrease emissions of greenhouse gases by 20 % by 2020, Swedenneeds to increase its use of bioenergy. In doing so it seems natural that those who already haveaccess to large amounts of biofuels in the form of by-products such as straw, wood chips anddigestible materials take advantage of these assets locally. By combining production of heat withpower production at the farm it may be possible to not only reduce the direct use of fossil fuel forheating but also reduce energy costs.The purpose was to simulate different cases of using a small scale biofueled combined heat andpower plant for farm-based systems. A MatLab-model was developed and used to draw conclusionsabout the costs for production of heat and electricity with different conversion technologies.The model uses climate data to simulate the variations in heat energy demand on a day-to-day basis.The given heat demand is the base of the simulation and from this the possible electric output iscalculated. This study has focused on the impact of the following properties: electric-, heat- andtotal efficiency, fuel, fuel price and specific fuel requirements.

Företagen riskerar att utsättas för förlustbringande värdeförändringar i tillgångar och skulder, eftersom de exponeras för olika marknadsrisker som fluktuationer i räntor, växelkurser, råvaru- och aktiepriser. För att skydda sig mot dessa fluktuationer och för att minimera exponeringen av marknadsriskerna, använder företag sig av olika typer av finansiella instrument. IFRS 7 är den standard som behandlar finansiella instrument och riskupplysningar. Standarden infördes år 2007, med avsikten att intressenten ska kunna tillgodoses relevant information om företagets hantering och exponering av finansiella risker.Syftet är att genomföra en studie på finansiella företag inom segmenten Large- och Small Cap och undersöka till vilken grad de efterföljer upplysningskraven beträffande marknadsrisker enligt IFRS 7, samt huruvida det förekommer något samband i upplysningsgrad och Cap-tillhörighet.Studien behandlar samtliga finansiella företag inom Large- och Small Cap-segmenten. Punkter i IFRS 7 som berör marknadsrisker har valts ut och företagens årsredovisningar har granskats för att undersöka upplysningsgraden och om det finns ett samband mellan upplysningsgrad och Cap-tillhörighet. Resultatet visar att företagen inom Large Cap-segmentet upplyste helt enligt kriterierna i 36 fall av 64 och företagen inom Small Cap upplyste helt enligt kriterierna i 9 fall av 32.

This thesis studies the concept of balance in the management control systems (MCS) of a small Swedish company within the IT-sector. The aim is to evaluate the importance of balance and dynamics in MCS and investigate which factors affect them. The frameworks used are Simons (1994) four levers of control, and the five-factor model for balance and dynamics by Mundy (2010). The small IT company - the object of the case study - has grown extensively in the last years and needs to develop more formal MCS without losing efficiency and creativity in their fast-moving industry. The case study reveals that balancing MCS is important also in smaller companies with less formal MCS.

The pupose of this study is to qualitatively study how teachers at a high school work with the schools demokratic mission under the management by objectives and what the policy document says and how the students can partcipate in different issues. My question fomulations are: What does it say in the governing documents about schools democratic mission and student influence? How do teachers concretely work to implement the values of democracy and student influence? How can the class councils used as part of the school's democratic mission? The theoretical frame of the study is about the school democracy mission and the possibilities and limits.  Futhermore a brief review of the fundamental values of the school are presented, followed by how the democratic process works.I used the qualitative analysis in order to find a lot of information about a small amount. Its strength is to convey a lot of information about a small number of observations and if the material is small in size.
