Testramverk för distribuerade system

When developing software that is meant to be distributed over several different computers and several different networks while still working together against a common goal there is a challenge in testing how updates within a single component will affect the system as a whole. Even if the performance of that specific component increases that is no guarantee for the increased performance of the entire system. Traditional methods of testing software becomes both hard and tedious when several different machines has to be involved for a single test and all of those machines has to be synchronized as well.This thesis has resulted in an exemplary application suite for testing distributed software. The thesis describes the method used for implementation as well as a description of the actual application suite that was developed. During the development several important factors and improvements for such a system was identified, which are described at the end of the thesis even though some of them never made it into the actual implementation.

HR-utmaningar och strategier för entreprenöriella små- och mikroföretag - En fallstudie på fem svenska företag

Entrepreneurial firms face unique challenges in attracting and acquiring human resources due to difficulties associated with resource constraint and organization legitimacy, often described as liabilities of "smallness" and "newness". The aim of this paper is to examine the "smallness" and "newness" challenges met by small entrepreneurial firms, which strategies they apply to counter these challenges, and if these strategies can be explained by the firm's HR philosophy. Since few studies on Human Resource Management (HRM) in small entrepreneurial firms exist, a framework combining theory from the research fields of HRM, entrepreneurship and small firms has been developed. Employing a qualitative case study design of five small Swedish entrepreneurial firms, our findings demonstrate four "smallness" and "newness" challenges and seven strategies that either counteract or prevent them. Furthermore, results showed that the strategies applied seemed to have no significance with regards to the firm's HR philosophy.

Undersökning : hur gestaltas den anlagda miljön vid naturum?

Rotavirus causes diarrhea in young mammals all over the world, including infant humans. The diarrhea leads to severe dehydration that can be fatal if left untreated. The dehydration can be treated with fluid therapy and the infection heals itself. Despite the relatively easy treatment half a million children under the age of five dies every year due to diarrhea caused by rotavirus. Rotavirus sorts into the family Reoviridae and is a double-stranded RNA virus with a segmented genome.

Utveckling av en Multi-Zonsmodell för NOx Bildning i Diesel Motorer

This thesis work is the last part of the Master of Science education inmechanical engineering at KTH, Stockholm.The aim of this project was the development of a Multi-zone modelfor NOxformation in Diesel engines. Because of the stringent emissionlegislations, great effort is made to decrease the fuel consumption and theharmful emissions of internal combustion engines. Computer simulationsplay a decisive role in this context because they substitute the expensiveand time-consuming laboratory tests.The model is based on a multi-zone approach and uses the wellknownExtended Zeldovich Mechanism which gives a relation to calculatethe NO formation rate using the concentration of different gas speciesinvolved in the process.All the most important phenomena involved in the Diesel combustionhave been modelled. A special attention is then paid to the equilibriumconcentration calculation; this is a significant part of the model whichstrongly influences the following steps.A Simulink model has also been developed. This second version isbased on the previous model and it is made especially to allow theconnection with other external softwares, GT-power in this case.

Fodder to ruminants within agroforestry systems in Rwanda - species and management

Rwanda is one of the poorest countries in the world and about 70-80 % of the population lives in rural areas. The land is strongly affected by land erosion which makes it difficult for the agriculture and food production. Agroforestry is a system where tree plantation is combined with livestock- and crop production. The system provides soil fertilization and binds the soil together. Some of the trees used in agroforestry systems are also used as fodder.

Ideologi, diskurs och miljöetik : - om ideologiska konstruktioner, pedagogiska publikationer och ekologiska komplikationer

The purpose of this investigation is to examine the extent to which Swedish compulsory school tends to rely upon, and to further reinforce, ideologies that from a theoretical platform of deep ecology can be identified as ?ecologically unsustainable conceptions of reality?. Mainly, this will purport to an examination of the (explicit as well as implicit) prevalence of anthropocenthrism, individualism, ethnocenthrism and rationalism in a) the Swedish National Curriculum; and in b) biology text books. Methodologically, the study makes use of Fairclough´s approach to, and method for, critical discourse analysis (CDA). The main results are that the National Curriculum indeed expresses a high level of individualism, as well as (although to a lesser extent) traces of rationalism and ethnocenthrism.

Vilka faktorer påverkar komposition och val av växter? : olika aktörers sätt att arbeta

The tomato is an important crop worldwide, and in recent years it has received great attention due to its rich content of carotenoids, which in studies indicate to have health benefiting properties. Many studies have been done in this area of research and in how to optimize the carotenoid content in tomatoes and tomato products. The objectives of this essay were to summarize present data in this field. The results were as follows:There are nine different carotenoids identified in tomatoes. Lycopene and ?-carotene are the ones that have been given the greatest attention.

Vad är problemet? - om konstruktionen av äldre invandrare som problem inom vård och omsorg.

The purpose of this essay was to see how the construction of elderly immigrants as a problem in healthcare and elderly care has been described in the relevant literature. In the course of doing so I tried to answer the following questions; What is said to be the expected problems or difficulties in work with eldely immigrants? How are the expected members of the problemgroup defined and identified? Whos perspective dominates the description of the problem, the users or the investigators? These questions were hard to answer and I had to conclude that the problem was not clearly defined; there was only an assumption of a problem. This, however, has not been a hindrance in the category of elderly immigrants being claimed to be a group with problems that need research and further investigation. The dominating perspective is that of the investigators as they are the ones who define and identify who is a part of the problemgroup..

Kompetensbegreppet i kommunal verksamhet : En kritisk diskursanalys

Large retirement numbers and fierce competition of available labour, results in municipalities have to be more attractive as an employer. One way for the municipalities to fulfil their staffing requirement is partly to increase their recruitment efforts, and partly to educate their existing employees. Discussions about the supply of competence are therefore pressing within municipal activity. The aim of the study was to investigate how the concept of competence is used within a municipal administration. The method that has been used is Norman Fairclough?s critical discourse analysis, a method that allows multi dimensional analysis.

Matematisk generering och realtidsrendering av vegetation i Gizmo3D

To render outdoor scenes with lots of vegetation in real time is a big challenge. This problem has important applications in the areas of visualization and simulation. Some progress has been made the last years, but a previously unsolved difficulty has been to combine high rendering quality with abundant variation in scenes. I present a method to mathematically generate and render vegetation in real time, with implementation in the scene graph Gizmo3D. The most important quality of the method is its ability to render scenes with many unique specimens with very low aliasing.

Sverige och Art- och Habitatdirektivet - i samförstånd eller avvikande : En studie om reglerande dokuments roll i implementeringsprocessen

Within the political science literature that deals with the implementation process a central part has long been what is sometimes called the implementation deficit. This means that the effect of a policy decision doesn´t turn out as it was originally intended. The often used explanation is that the policy decisions moves through many levels during its implementation where different actors can change or alter the decision in various degrees. This phenomenon has gradually become more and more attended within the legislative process in the European Union and has been addressed in numerous studies. The purpose of this paper is to examine the implementation of The Habitats Directive, as its embodied in regulatory documents, in the Swedish multi-level system.

Miljöteknisk undersökning enligt MIFO : en studie på fastigheten Bodsjölandet 1:14 avseende den nedlagda tjärfabriken i Grötingen

During 40 years of industrial production, from the end of the 1890?s until the end of 1930?s, coal and wood distillation products were manufactured in AB Carbo?s tar factory along the River Gimån in Grötingen, in the county of Jämtland, Sweden. In accordance with the Swedish Environmental Protection Agency?s Methods for Inventories of contaminated sites, MIFO, the site in Grötingen has been identified as a potentially contaminated site. In order to determine whether toxic substances pose a threat to human health and ecological systems in the area, there was a need to investigate the presence of contaminants, their levels and potential for migration.

Att skriva sig till läsning : Möjligheter och begränsningar ur ett pedagogiskt perspektiv

This thesis intends to analyse conditions for a successful implementation of consociational democracy, as a democratic model in Afghanistan. The lack of critical reviews regarding the democratisation-process in Afghanistan initiated the purpose of this study.Lijpharts democracy model was used as the basis in the comparative study. Along with empirical evidence regarding how the complex process of democracy in Afghanistan is progressing, the study investigated whether the identified conditions occurred or not.The choice of which democracy model to use can be crucial for the democratic possibilities to even survive and become established in conflict-affected communities. The principle of consociational democracy is that it is an empirically based normative model that aims to organise the state in a way that works against the risks of majority domination and oppression against the minority.The empirical case study revealed that a majority of the conditions were not met, which then can counteract the possibilities for consociational democracy in Afghanistan. The study has critically examined the prospects for the success of consociational democracy in Afghanistan, and it can be assessed that there is a limited probability for a successful applying of this model..

Bilden av spelaren : En diskursanalys om att göra "problem"

The purpose of this study has been to examine how the image of the gambler is described by studying a report published by Folkhälsoinstituet [FHI] and a number of chosen articles from the Swedish Evening Press. Discourse theory has been used both as theory, together with social constructionism, and as a research method. The main conclusions of the study are that three different discourses can be identified: the normal gambler, the professional gambler and the problem gambler. The image of the problem gambler is described as a deviant and problematic minority characterized by loss of control, irrational thoughts and dissociative behaviour. The construction of the problem gambler fills three possible purposes for the state: As a solvable problem to handle criticism against negative consequences of gambling, as an argument to avoid competition on the market and as an individual characterized by loss of control in order to legitimize and make the construction of the normal gambler possible..

Flodpärlmusslans status i Laxtjärnbäcken : Effekter på flodpärlmusslan av sedimentbelastning och förekomst av bäckröding

The aim of this present study was to determine and evaluate whether the presence of brooktrout (Salvelinus fontinalis) and sediment load may be a threat against the reproduction anddistribution of freshwater pearl mussel (Margaritifera margaritifera) in a creek located innorthern Sweden. Freshwater pearl mussel is an endangered species and is dependent ofbrown trout (Salmo trutta) to reproduce. Therefore there are concerns of indirect effects onthe population of pearl mussel by competition between brown trout and brook trout. Ditchesfrom a nearby gravel road have been fixed to lower the sediment load into the creek. I tried toevaluate this action plan.
