Multilateral och unilateral säkerhetspolitisk praktik och strategi för hantering av Syrienkonflikten
This security study attempts to explain the dynamics of international conflict management of an intrastate conflict, through a combination of three theoretical frameworks. The conflict in Syria is shown to be managed mainly through strategies using coercive diplomacy, and some main contributions within the research field relating to strategies of coercion are used for guidance, to important factors which could affect coercive international conflict management, as well as to additional theories which could enhance the study?s explanatory power through a combined theoretical framework. The two added theoretical frameworks are Power Balancing and a Multidimensional concept of Power. With the aid of analytical tools derived from this combined framework the conflict management is analysed within both a multilateral and unilateral setting, offering some explanation as to why international conflict management (practiced by UNSC multilaterally and USA unilaterally) has shown so little progress in regard to the conflict, as well as why one significant, though limited, result could be achieved regarding the destruction of the Syrian regime?s chemical weapons arsenal..
Boka en bibliotekarie - en studie i förmedlad informationssökning
This master thesis deals with events, dynamics and problems of mediated information seeking within the context of a new information service called "Book a librarian". The study, based on a survey and interviews both in academic and public libraries and participant observations in academic libraries, has its theoretical base in the cognitive theory of information retrieval interaction. The cognitive view is used to throw light upon the need of an ongoing dialogue during the session in order to detect the information needs of the user and to conduct a successful retrieval of information. The communicative interaction is seen as threepart interaction between the intermediary, the user and the information system, where the current cognitive states of all three participants are involved. The study shows that the cognitive obstacles for a successful mediation and information retrieval are mostly connected to participants current knowledge of the subject and of the retrieval techniques.
Studier av utseendet på askan i sodapannor med hjälp av bildanalys
To reduce emissions of carbon dioxide (CO2) Carbon Capture and Storage (CCS) technologieshave been developed. Chemical Looping Combustion (CLC) is a CO2 capture technologywith the CCS framework, and at Chalmers University of Technology in Gothenburg,Sweden, a 100 kW chemical looping combustor has been built.This project aimed to investigate to what degree air can replace helium as the uidizinggas for uid dynamical studies in a CLC cold ow model of the above mentioned 100 kWfacility. Experiments were performed using air and helium separately as uidizing gas andpressure data were obtained, which formed the basis for the comparison. The project alsoaimed to investigate uid dynamics in the uidized bed and study when the risk of sluggingoccuring was greatest. The results were presented in the form of figures and tables dividedinto pressure, concentration and standard deviation of the pressure.The results obtained showed that air as uidizing gas did not create the same uid dynamicsas helium over the entire fuel reactor.
Gravritualer vid gånggrifterna på Falbygden : En undersökning av den materiella kulturen inne i och utanför graven
This essay is about the burial rites in the passage graves of Falbygden, Västergötland. My questions were: Can the burial ritual be understood by comparing the material culture inside and outside the tombs? What kind of grave offerings did the dead have? Most peculiar are all these beads of amber, what kind of meaning did they have? Was the position of the body a part of the ritual? The time period is the middle Neolithic.I selected four passage graves to investigate: Hjälmars rör (Falköping 3), Rössberga (Valtorp 2), Näs sn 7:2 Kvättak 5:1 and Frälsegården (Gökhem 94).My conclusion was that there are differences between the material culture inside and outside the tombs. Outside the ritual includes fire, inside the material culture are not burned. The material culture outside is more dominant than the finds inside, although the beads of amber are only represented inside and dominates the findings inside.
Dynamisk simulering med hjälp av RPS-beräkningar för radiovågors utbredning i urban miljö
Militära insatser i urban miljö kommer troligen att öka alltmer. Detta kräver soldater till fots eftersom dessa lättare kan förflytta sig via och mellan byggnader. Varje deltagande soldat kommer att behöva egen radioutrustning. Då stadsmiljö är ett relativt outforskat område vad gäller militär radiokommunikation är det viktigt att öka förståelsen för radiovågors utbredning i stadsmiljö. Härtill har institutionen för Informationsöverföring på FOI köpt in programmet Radiowave Propagation Simulator (RPS).
MPD-vågformer för helikopterradar
A helicopter based system equipped with a millimetre-wave fire control radar is studied for improvement of the detection probability for moving ground targets. The system is a pulse doppler radar that sends out the electromagnetic wave in repetitive pulses. The frequency in which radar sends this pulse is called Pulse Repetition Frequency (PRF). The velocity of the moving targets is measured by spectral analysis of the pulses received. With this sort of system some targets will not be possible to detect.
How Venture Capitalists can use their Network in order to reduce the Information Asymmetries between themselves and the Venture Management Team
The purpose of this study is to increase the understanding of how venture capitalists can use their network in order to reduce information asymmetries between themselves and the venture management team. A qualitative approach with semi-structured interviews, consisting of open questions, have been used to receive gradate information in order to reach our explorative purpose. Our theoretical framework consists of relevant studies made on the dynamics of networks and the problems that can arise in the complex relationship between a principal and an agent. We have been interviewing two venture capital firms and therepresentatives from two business angel networks. We also made an additional interview with an influential financial actor in order to try to verify our conclusions Our conclusions are that an extensive network can be used by venture capitalists in order to; verify ventures? technologies, complement the competences in the venture management team, and arrange co-investments, resulting in reduced information asymmetries between themselves and the venture management team.
Dynamisk modellering av kärnreaktor
The purpose of this thesis has been to develop a tool for modelling and simulating the nuclear plant Ringhals 3. The model should be used to improve the knowledge on the dynamics of the plant. Ringhals 3 is being upgraded to produce more power and a tool for analyzing the new operating conditions is needed.The work in this thesis has consisted of improving and developing an existing model of Ringhals 3 made with the modelling tool Dymola. The model has been validated by comparing the results of a simulated house load transient with data from the actual plant. Validation shows good agreement with data from the real plant.
Samhällskunskapsämnet över tid : En undersökning mellan läroplan och läromedel från 1962 och 2011 i ämnet samhällskunskap
This essay is from a student at the cultural science program in Karlstad University. The essay in Culture studies deals about the history use and about the cultural-historical values on buildings. The buildings are from a certain area called the neighborhood Almen and have in the past been threatening many times of demolition. The neighborhood Almen buildings survived a huge city fire back in the 19th century. Since then the buildings has been known as a memory and by the inhabitants and as the oldest part of the city left.
Sensor för hydraulolja
This is the final documentation of the basis that can be the foundation of how to solve theproblem with leaking hydraulic oil in a shoe press at the company Albany InternationalAB in Halmstad, Sweden.The project has been performed at Halmstad University as a degree project commissionedby Albany International AB. The purpose of the degree project was to find a way ofdetecting the hydraulic leak of a shoe press. The reason is that the shoe press runsunattended during nights and weekends, this can cause an extensive decontaminationwork and production stop if leak. The hydraulic oil could be leaking in large amounts orslowly as a fine mist. The development of a working system that can detect a hydraulicoil leak and stop the machine before a large amount of hydraulic oil leaks out wouldconsiderably reduce the cost of the decontamination work.
Decision making and the role of empathy in animal ethics committees (AECs)
Ethical evaluation of scientific studies carried out using animals is legally mandated in many countries and has been so in Sweden for over three decades. The animal ethics committees (AECs) responsible for the task have however been subjected to criticism; common critique being that the wrong issues are discussed and that the ethical evaluation is thus incomplete, that there is a lack of coherence across committees and that the committees are not as democratic as they might appear. This study investigates the view of Swedish AEC members on a number of issues in order to shed some light on the mandate and functioning of the committees, and on the grounds for ongoing criticism. In a survey and interviews AEC members and other persons connected to the committees gave their views on the AEC task in relation to their roles, the ethical evaluation per se and whether or not emotions such as empathy play any part in it. There were significant differences found between AEC member categories and several issues were encountered, many of which have been stressed in previous studies.
Intressekonflikten mellan polisiära spaningsmetoder och förhör
This essay is about the meeting of the pedagogic mission and the reality of the conditions in preschools. It is about the frustrations that I, as a pedagogue, experience when I cannot fulfill this mission. An example of this is working when understaffed.My purpose is the acknowledgment of two main areas of the curriculum: caring and learning. This essay demonstrates the diversity of the occupation and it ?s constant need of positioning.
Överföring av kunskap : från spel till verklighet
Denna undersökning behandlar spel i kontext till lärande och matematik. Genom att gestalta ett spel undersökte vi, författare hur olika designval kunde påverka lärande. Målet var att spelare skulle lära sig genom situationsbaserat lärande och där genom få möjlighet att överföra sin kunskap till sitt vardagsliv. Undersökningen hade sin utgångspunkt i ANT (actor-network theory) som användes som metodologi för att analysera och reflektera över de val som gjordes. MDA (Mechanics Dynamics Aesthetics) användes som ett ramverk för att utveckla själva gestaltningen.
