CLEAN SEA : ALGSKÖRDNINGSMASKIN
Under vårt sista år var vi intresserade av att ta reda på de problem som vi kan stöta på i våra yrkesroller som fartygsingenjörer. Arbetet tar upp de tekniska problem som uppstår p.g.a. de allt strängare kraven på minskade svavelutsläpp från fartyg. De tekniska problemen härstammar från de olika bränslekvaliteternas vitt skilda egenskaper. Som svar på dessa problem har det utvecklats tekniska lösningar varav två stycken har tagits upp i detta arbete.För att ta reda på vilka tekniska problem som kan uppstå tog vi del av den berörda utrustningens tillverkares erfarenheter enligt empirisk modell.
Barns inflytande i förskolan : Pedagogers perspektiv
The purpose of this study was to find out what pedagogues in preschool think when it comes to children?s influence and how they do to give the children opportunity to express their thoughts and point of views and thereby influence their situation.The literature review treats the conception of the competent child and shows that having child perspective is important in meeting children. The literature review implies that participation and influence means sensitivity to children?s expressions and that pedagogues lets these expressions influence the activities in preschool. It is not about children always getting their ways, but that they are respected and are given space to think freely.Searching for pedagogues? thoughts on children?s influence and how they do for giving it, I interviewed six persons, working at six different preschools.
Skalkonstruktion : Med inriktning mot hållfasthet och dämpning av ljud
The sound part is mainly practical and is dependent on concepts that have been tested through measuring with a sound level meter. The design part is more theoretical and has been verified with CAD models and finite element analysis.With a sound damping hood on the compressor the sound level is reduced with up to four dB. An optimized absorbent for the compressor space gives a reduction with three dB. By using the insulation for the heat water tank as absorbent we can see a sound reduction on the lover octave bands. A reduction like this is elsewhere hard to achieve as at it requires thick absorbents.By changing the today?s insulation to the heat water tank to a form of polystyrene polymer insulation the weight from the heat pump above can be transferred to the stable heat water tank.
Ytstridsfartygs ballistiska skydd mot finkalibriga projektiler
This paper is about the extent to which simplified penetration calculations ofsmall-caliber projectiles is a useful tool for assessing the physical protectioncapability. The work should be seen as an attempt to create an accessible tool inthe form of a simplified equation that allows for a better and safer use of thenaval vessels. The tool will also be used at different levels so that decisions andinstructions could be clearer.Performed calculations show a very limited capacity of a ship's basic design interms of physical protection against the use of small-caliber projectiles.How do we know that the calculations correct? By verifying the calculations withpractical shooting tests, a substantial condition to answer the question will becreated. To shoot against a material with two different thicknesses estimated toproduce perforation and non-perforation is a good approximation of the equationusability in the context..
Reglering av naturgasdistributörer : En undersökning av benchmarking på marknaden för naturgasdistribution
This paper discusses the advantages and disadvantages of using different benchmarking models to measure and compare the efficiency of Swedish gas distributors. It also discusses to which extent the results of a benchmarking study should influence the revenue-cap which will be implemented in the gas distribution sector in Sweden from year 2011. The discussion is based on arguments from both theory and practical applications of benchmarking. The results suggest that benchmarking Swedish gas distributors against distributors in another country using a parametric model is most favorable, but the reliability will be increased if non-parametric models are used also. Partial and total productivity measures could be used to confirm results of other benchmarking analyses.
Sjuksköterskors upplevelser av att vårda patienter med psykiatriska problem på en somatisk akutvårdsavdelning
Syftet med studien var att beskriva sjuksköterskors upplevelser av att vårda patienter med psykiatriska problem på en akutvårdsavdelning i södra Sverige. Tidigare forskning finns om sjuksköterskans attityder till att vårda patienter med psykiatriska problem, men kunskapen om sjuksköterskans faktiska upplevelse av att vårda denna patientgrupp är mindre studerad. I studien är det sjuksköterskans egen definition av vad som är ett psykiatriskt problem som ligger till grund för resultatet. Sex intervjuer har genomförts och transkriberats ordagrant. Materialet har analyserats med kvalitativ innehållsanalys inspirerad av Graneheim och Lundman (2004).
Matematisk problemlösning
Matematiskproblemlösning blir en större och viktigare del av matematikundervisningen närtekniska hjälpmedel, som miniräknare och datorer, kan utföra många beräkningar.Undersökningens syfte är att se hur gymnasieelever löser matematiska problem. Vilka faktorer som påverkar vid problemlösning samt vilka moment eleverna har svårt för. Undersökningen genomfördes på en gymnasieskola I Halmstad där atta elever med varierande matematikkunskaper löste fyra problem och ingående redogjorde för hur de tänkte och gick tillväga. Teorikapitlet tar upp olika matematikdidaktikers syn på problemlösning, modeller för hur problemlösning går till och faktorer elever besitter som påverkar möjligheten att lösa problem. Jag har med hjälp av dessa modeller och påverkansfaktorer analyserat elevernalösningar enligt en modell bestående av tre delar: Identifiering, genomförande och kontroll av uppgiften.
Objektskoncentration vid slutavverkning
The study is made on behalf of SCA Skog Jämtlands förvaltning which is one of five administration units that SCA Skog consists of. The purpose of the study is to investigate which reduced expenses there are according to spatial concentration of cutting areas. By increasing the spatial concentration of cutting areas it will reduce the need of movements by trailer, also reduce the number of roads that you use during the activities.
To be able to perform the study, access to a annual cuttings in nine years have been made available. From this volume new annual cuttings has been created but more concentrated. The two different results have been compared and the results show that concentration of cutting areas generates reduced need for trailer transports and less km road that has to be maintained.
But then, if it´s practical viable can be discussed.
Leka och lära på lika vilkor? : En studie kring fritishemmets arbete om barn med koncentrationssvårigheter
The purpose has been to investigate leisure-time centers actual work on children with attention deficit disorder. In addition, the study strives to make leisure-time centers way of working, in relation to their assignments, visible. The study has also compared how the leisure-time centers work and what the research says. The survey was conducted with the help of three exploratory interviews with pedagogues and three-piece observations at the leisure-time centers. It was carried out at three different schools in two counties in Sweden.The results of the survey show that the schools are trying to create clear procedures, though the centers succeed with this in varied degrees.
Individanpassning vid val av HVB-hem. "Hemma är inte alltid där du bor, utan där du är förstådd".
The purpose of this essay has been to study if the social services adjust the choice of institution to every juvenile's need of care. If the choice of institution isn't adjusted to the juveniles the institutional placement can become a way to store them rather then treat them.To accomplish the purpose of the essay we have interviewed ten social workers with different worktitles and positions. We have delimited the study to three swedish communities with varying sizes. We have analyzed the material with Bourdieus theory of "field" and "doxa" and Antonovskys theory "a sense of coherence" (SOC).We came to the conclusion that the social service adjusted the choice of institution to the juveniles needs as much as possible. Although there are a couple of factors that some times makes the best choices impossible.

Kan man tala om en norm utan att befästa den? : En diskursanalys i hur homosexualitet behandlas i läromedel riktade till skolans senare år.
The purpose of this essay has been to investigate the research and national initiatives regarding film and Cineliteracy in the Swedish curriculum.The results show that, after all research, national initiatives and the continual clarification from the Swedish National Agency for Education concerning film's place in the Swedish subject, the vision of students cineliteracy not at all obtain an obvious place in the curriculum.The research points out the main causes behind this result to be teachers' lack of expertise and the fact that the formal education for future teachers in the subject still upholds traditional views on the subject of Swedish.The initiative presented in this essay also show lack of continuity, lack of adequate professional development opportunities for teachers and lack of practical guidance manuals to help teachers to develop and educate their pupils in line with current research and visions. .
