Fartförlust på grunt vatten : En jämförelse av bränsleförbrukning och tidsåtgång för rutter med olika djup och distans
Denna studie handlar om den fartförlust och därmed den ökade energiförbrukningen som drabbar fartyg på grunt vatten. Syftet var att ta reda på hur mycket kortare en grund passage behöver vara för att den ska vara ett bättre alternativ än en lång och djup rutt med hänsyn till bränsleförbrukning och tidsåtgång. Resultatet av detta blev att det inte går att dra några generella slutsatser som gäller för alla fartygstyper men att det går att se tydliga tendenser. Studien hade även som målsättning att skapa ett underlag som skulle kunna användas av nautiker vid planering av resor, detta presenterades i form av en sammanställning av de resultat som erhållits vid beräkning av fartförlust i öppet vatten. Någon sammanställning gjordes inte för begränsat vatten eftersom exempelfartygen där fick likadana resultat vilket skulle ha gjort en sådan överflödig.
Måluppfyllelseprocessen i gymnasieskolan : Lärares intentioner, handlingar och elevers reaktioner
Syftet med studien var att kartlägga, belysa och förstå hur måluppfyllelseprocessen fungerar på en gymnasieskola med yrkesförberedande program. Med måluppfyllelse-process menar vi alla aktiviteter där lärare tolkar och förmedlar kursmål, bedömer prestationer samt förmedlar denna bedömning. Vidare är syftet att studera elevernas delaktighet i och reaktion på denna process. Studien genomfördes med en kvalitativ ansats med faktaintervjuer och fokusgrupps-intervjuer. Vi har tagit utgångspunkt i Vygotskijs teori om den proximala utvecklingszonen och begreppen formativ och summativ bedömning.
Klinikintern statistik : en fallstudie kring behov av och möjligheter till framtagandet av ett statistikverktyg
The health care sector is one of the most information-intensive institutions in Sweden. Big investments in information technology have been made to ensure efficiency and quality within organisations in health care. This has led to high requirements in documentation and resulted in an increase in administration which gradually more often is done by nurses and doctors. A major problem is that it is difficult to gain access to the information recorded in all the different systems, which is their objective. This causes double documentation instead of being a support in follow-up performance.
Kartläggning av Kassationerpå Bubs Godis
The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.

Den sista utvägen... : ? En kvalitativ studie om psykiatripersonal och brukares inställning till elektrokonvulsiv behandling (ECT).
ABSTRACT Nature of essay: C-level, 15 pointsPage count: 47Title: The last way out?-A qualitative study of psychiatric staff and service users attitude to electroconvulsive therapy (ECT).Author: Hanna Nilsson Purpose: The purpose of this study is to investigate attitudes to electroconvulsive therapy (ECT) of professionals and service users within a user organization ? Riksförbundet för social och mental hälsa. (RSMH)Questions: Does the psychiatric staff believe that there are preconceptions about electroconvulsive therapy? What motivates service user?s choice of electroconvulsive therapy? Do the psychiatric staff and the service users think that the positive effects of ECT can outweigh the possible negative side effects?Method: Qualitative study. The study is based on interviews with psychiatric staffthat works with electroconvulsive therapy (ECT), and with services users who have received electroconvulsive therapy (ECT).Results: The result showed that the psychiatric staff feels that preconceived ideas occur about the treatment of ECT, and that it is affecting their approach to work.Service users motivate their choice by how bad they felt under the depression, and that ECT was their only choice left, that´s why psychiatric staff suggested the treatment.The positive effects of ECT outweighed the possible negative side effects because life is something you value higher than any memory loss and when there is currently no treatment having a similar efficiency.Keywords: Electroconvulsive therapy, Attitudes, Side effects, Experience, Patients, Professionals.
Distributionsekonomisk optimering av dagligvaruhandelns lokalisering : förstudie till ett forskningsprojekt
The structure and performance of grocery distribution in Sweden has changed profoundly since the second world war. Increasing access and usage of the private car, in combination with an accommodating town planning has enhanced the exploitation of scale economies within distribution firms. There is, however, some ambiguity concerning the overall efficiency of the distribution system when the costs associated with travelling and purchasing performed by households are treated as an integrated part of the total distribution cost function. The purpose of this master thesis is to develop the foundation of a spatial optimisation model, which defines the most efficient distribution system. The underlying idea is that the optimal localisation and size of grocery stores is a function of economies of scale within the firms weighed against distributions costs within the households, such as transportation costs.
Studie av belagda kolvringarmot plasmasprutat cylinderfoder : Med avseende på friktion och nötningsmotstånd
Future emission legislation puts great emphasis on increasing the efficiency of the engine, thereby reducing fuel consumption. The tribological contact between cylinder liner and piston ring is where an great amount of energy is lost due to friction, and by reducing these losses an reduction in fuel consumption can be achieved.The aim of this thesis was to evaluate the tested piston ring coatings against a plasma sprayed cylinder liner and rank these combinations of materials for friction and wear resistance. The coatings that were tested was Cr + Al2O3, (Al,Cr)N, two types of CrN and WC / C.The experimental tests were performed with a so-called pin-plate, where used oil with addition of an acidic mixture of sulfuric and nitric acid to mimic the acidic condensate formed when exhausts recirculate, were added with a continuous flow. The results were then analyzed by weighing, studies by optical microscopy and scanning electron microscopy (SEM) and profile measurements.The results from each material combination were that the plasma coated cylinder liner wears too aggressively in order to yield a ranking of the piston ring coatings based on the parameters of friction and wear resistance. It is therefore proposed that an alternative coating on the cylinder liner should be developed, lacking the large abrasive wear on piston rings and that can withstand the corrosive environment resulting in engines equipped with EGR.
Produktionseffektivisering : - Få processens samtliga aktörer att sträva mot samma mål genom ökat samarbete och delaktighet i produktionens olika skeenden.
The productiontime in the construction industry contains of many different participants which will take part in different events. When there is so many people working with the same project it is easy tosee one self just as a part of the game. The consequence of this is that they don?t see themselves as important participants whos knowledge, opinions and experience can be useful in the whole production process. This might lead to that they feel neglected and the consequence of that will be lackof motivation.
Nyblivna mödrars erfarenheter av initiering av amning : En jämförelse mellan tre kliniker
ABSTRACTThe aim of this study was to describe various methods of treatment and effects of treatment of ADHD, and to investigate wheater there is an association between adults with ADHD and obesity. Method: Literature review. Twelve quantitative scientific articles were found in the data bases PubMed, Cinahl and MedLine. Result: ADHD is a cognitive impairment that can lead to serious complications such as obesity. Studies show that drug treatments of adults with ADHD have positive effects in terms of reduced symptoms, increased efficiency and improved quality of life, but drugs can also cause side effects in form of loss of appetite and insomnia. For adults with ADHD and obesity drugs that affect metabolism have a significant impact on patients ability to lose weight.
Demokratins väktare? : En kvalitativ studie av hur personliga handläggare på Försäkringskassan upplever och hanterar målkonflikter
The purpose of this essay is to examine how administrative officers at the Swedish social insurance agency experience and deal with the goal conflicts they may experience. Furthermore, the purpose is to gain a greater understanding on how they perceive their role in the implementation process, and their position as the link between the citizens and the state. Two potential conflicts are examined; between quantitative goals and performance measures and those more qualitative and hard to measure; between economic values such as cost efficiency and productivity and democratic values such as the rule of law. The other conflict examined is that between implementing and following the laws set forth, take into account the individual needs and interests of the citizen. The theoretical framework consists of Lundquist?s theory on public officers as the guardians of democracy, which means that they should not only implement laws and rules according to political intentions, but also make sure that the democratic values and principles are followed in the relationship between state and citizen.
Att mäta eller inte mäta? : En kvalitativ undersökning om prestationsmätningar på en av Blekingesjukhusets kliniker
Blekinge Hospital suffers from a budget shortage of 100 million SEK, while the government now requires that hospitals will no longer be running a deficit. Blekinge Hospital will then use their limited resources to survive in the future and the activity must be enhanced in order to keep costs low without having to lay off personnel. The idea is that the organisation should be more efficient with a more efficient resource usage. Performance measurement systems are important tools for achieving the policies set out within an organization, measuring and evaluating performance is a way to see where improvements in efficiency may be necessary in the business. Balanced Scorecard (BSC) is one of several measuring systems, where the focus is on measuring non-financial performances.

Organisatorisk kunskapshantering : En fallstudie hos Polisens verksamhetsstöd
This report deals with the theory and empirical evidence of how knowledge generated within a project is to be captured and shared with other projects and the surrounding organization, after the end of a project. A number of authors have highlighted knowledge management within a company as a key component in building a unique competitive advantage and knowledge should therefore be considered a very important resource within companies. The difficulties of ensuring that knowledge generated within a project can benefit other projects are many. The nature of the project form has been highlighted as one of the biggest problems, due to the fact that budget and time requirements often restrict the propensity to work with knowledge transfer. Other difficulties that this report highlights are in particular the lack of a knowledge sharing culture within the organizations, as well as human cognitive and psychological limitations and lack of tools design for knowledge transfer.
