Transportoptimeringar med hjälp av flödesanalyser

Detta examensarbete utgör resultatet av en studie på uppdrag av Volvo Cars Torslanda (VCT) i Göteborg. Syftet med studien har varit att undersöka produktflödena mellan VCT och dess leverantörer med hjälp av analyser. Dessutom utreds hur transporterna skulle kunna optimeras och vilka konsekvenser som uppstår. Beräkningar, diskussioner och analyser resulterar i rekommendationer för företaget.För att få mer kunskap om transportlogistik, produktionsekonomi och miljöpåverkan av transporter genomförs först en litteraturstudie. En granskning av nuläget beskriver hur situationen ser ut i dagsläget och ger även en detaljerad bild av flödena från leverantörer till VCT.Sex stycken flöden vars gods transporteras från leverantörer till VCT har undersökts.

KOGNITIV PROBLEMLÖSNING UNDER STRESS : PÅVERKAR FYSIOLOGISK AROUSAL PRESTATIONEN?

Förmågan att prestera under akut eller kraftig stress är en förutsättning för en del yrken. Forskningsresultaten gällande hur stress påverkar prestation pekar åt olika håll. Denna studie undersökte sambandet mellan fysiologisk arousal och kognitiv problemlösningsförmåga under stress. Trettiotvå polisstudenter testades på Ravens test av flytande intelligens APM set II både före och efter att antingen ha sprungit i tjugo minuter eller haft en självskyddslektion på ca fyrtio minuter. Resultaten från en mixed ANOVA för beroende mätningar visade på en signifikant interaktionseffekt (F (30) = 6,547, p < 0,05) ? en ökning i prestationen hos självskyddsgruppen med arton procent och en minskning med femton procent hos löpningsgruppen.

Tillämpning av nya beräkningsmetoder för branddimensionering av  träkonstruktioner - analyser och jämförelser

To build high-rise buildings made of timber has for long been limited by national laws, due to the lack of knowledge in engineering solutions. Frame structures made of wood has for a long time been associated with major fire hazards and consequently lower safety and this connection is still being made today. The increased environmental awareness in recent years has contributed to the exploitation of indigenous building materials, including wood from our own Swedish forests and has become increasingly common. Increased knowledge about how structures behave in fire and how they can be protected in order to achieve safe timber structures has resulted in a growing interest in these structures in the construction industry. Research in the area is constantly updated and new laws allow any number of storeys in wooden buildings in Sweden as long as the performance requirements are fulfilled.The main part of this work has involved calculations of the fire resistance and load bearing capacity of floor and wall constructions.

Samverkanspelare i icke bärande fasadelement

AbstractThe tests work is about the subject "synergism of steel and concrete."The construction sector is in a strong competition and the different companies in the PrefabMarket has ever tried to develop new design solutions that are efficient and environmentallyfriendly.The purpose of this report is to highlight different aspects of interaction and size up a columndimension and to examine its efficiency and load capacity as Eurocode 3 and Eurocode 4. A sizing chart that describes the relationship between the torque and normal force shouldalso be made of the interaction . .

Nutritionens betydelse för akut traumatiskt hjärnskadade patienter

The aim of the literature review was to illuminate the importance of nutritional management to patients who have sustained a traumatic brain injury (TBI) and describe nurses responsibility and meaningful function in the nutritional support. TBI patients tend to be associated with hypermetabolism and hypercatabolism, resulting in negative nitrogen balances. The results reveal increased energy expenditure and assessments of needs energy requirements at the TBI patients. This study determining the route of feeding: enteral versus parenteral nutrition. Furthermore describes complications associated with enteral feeding.

Eurons dolda agenda Hur externa faktorer kan förklara skapandet av EMU

The aim of the thesis is to highlight external factors to explain why the EMU was created. The external factor considered here is the monetary policy of the United States, which often conflicted with European interests. The statistical data in the thesis, as well as previous research, show that even though the EU economically in many ways had become an equal partner of the US during the second half of the 20th century, the union still faced US influence and dependence.The results of the thesis can be explained with neorealist theories on power measured as an actor's distribution of capabilities and balancing of power. An actor that is equipped with the world's leading currency is more independent from others. Other actors, on the other hand, become increasingly dependent on the major currency and the policy of its owner.

Förändringar i markanvändning över tid och dess påverkan på vattenkvalitet

The EU Water Framework Directive has led that management follows the boundaries of natural catchments.The Swedish waters suffer from a nutrient overload that originates mainly from diffuse sources such as agriculture and the subcatchment of Hackstabäcken in Vallentuna Kommun, just north of Stockholm, has been chosen for this study because of its high nutrient load and because it has undergone obvious changes in land use through the years.In this study, the land use in 1902 is compared with the land use in 2011 in order to investigate if it has influenced the ability of the landscape to produce ecosystem services related to nutrient removal. These services will continue to be produced as long as the system is stable and resilient, but when landuse changes and manure from horses increases it will lead to disturbances that can convert a system from one regime in to a completely different one. That will result in loss, or degradation, of ecosystem services such as denitrification, phosphor sedimentation and adsorption, vegetation uptake and infiltration.The results of this study are based upon area calculations of landuse from old maps from 1902 and 2011. Through these maps it becomes clear that the forests in Hackstabäcken, has increased with 170 ha together with an urbanization of 311 ha, at the same time as wetlands and arable land has diminished and lakes has suffered from reductions. Wetlands have been reduced with 76 ha and the ones remaining are of insufficient quality from a nutrient removal perspective.Data from 1902 and 2011 regarding number of horses and bovines indicated a decrease in bovines and an increase in horses.

Students balancing human capital through scorecard - a study of non-profit organizations

PURPOSE: By analysing collected data using theory, we aim to interpret the design, implementation and the usage of BSC in NPO?s to be able to contribute to the research. METHODOLOGY: A case study design has been made through semi-structured interviews and backed up by a quantitative survey and internal documents. THEORETICAL PERSPECTIVES: Based on the sources given from the creators of the scorecard together with some sceptics and some followers, we have outlined the bases of balanced scorecard. To map out the non-profit sector and its strategic needs, the theories have tried to settle the specific need for the strategic tool given.

Avspecialisering som framgångskoncept för jämnare arbetsfördelning?

The application of the LSS law and how the public organization (Municipality of Hudiksvall) later had to reform their organization to fit the new demands is the foundation to this master's thesis. An internal evaluation was performed due to this reorganisation process within the social care department (LSS unit). The aim was to investigate and evaluate if the reorganization resulted in a better working environment and if the work load (distribution of work) became more evenly divided between the different unit managing directors. The primary empirical information to this master's thesis is collected from that evaluation report. The main aim of this master?s thesis is to answer if the organisational choice between specialised or de-specialised working tasks has an effect (experienced and measured) on the level of stress among the unit managing directors.

Evidens eller referens?: vad påverkar rektorers beslut?

Today the school is a given place for preventing social problems. The school struggles continuously to live up to the expectations of balancing preventive social work with pedagogy in a satisfactory way.The purpose of this essay is to get a picture of priorities of social work in school. I want to know what it is that affects and controls the principal's decision about what kind of social project they will accept and be a part of.This essay shows that only one of the eleven principals interviewed apply projects based on evidence when they decide about participation in a social project. Instead, the decisions are based on references from other schools. The reason why the principals do not base their judgement on projects which are based on evidence is because they consider the search for results too time consuming.When there is no requirement that a certain part of the social work in a school must be based on evidence, it leads to the children taking part in different social projects which we can not guarantee are good for them.One solution can be to guide the principals through a national social teachingplan, which can assure that social work based on evidence are being applied in the municipality schools as well as the independent schools..

Kylapotentialen i Drefviken för Vattenfall Heat AB

Vattenfall Heat AB is a district heat provider in Drefviken, but has yet to establish any cooling systems in this area. This thesis examines the potential client base within the area today and over the coming 20 years. The feasibility of the most common cooling technologies is evaluated and results show a total potential for an installed capacity of 30 MW providing 50 GWh of cooling per year. One of the examined areas shows good prospect for heat driven absorption chillers during the summer months when the heat load is limited..

Lärarens första ljuva år som ledare : En kvalitativ undersökningom fem nyutexaminerade 1-6 lärares föreställningar kring sitt ledarskap

The purpose of this essay is to find out what new graduate teachers conceptions are of their own leadership in the classroom. The paper also aims to examine the different leadership styles the teachers perceive themselves to use. My study is based on qualitative data collected through interviews, where the informants are newly graduated teachers in grade 1 to 6. Using a qualitative approach has made it possible for me to get a deeper understanding of this study. I have also used previous research in this area where Arfwedson (1993), Franssons & Morbergs (2001) and Paulin (2007) presents a number of experiences that student teachers and recent graduate teachers has shared.

Näringsretention i återskapad våtmark på betesmark : studier av en mad vid Bornsjön

It is important to construct or recreate different types of wetlands and study their retention of nutrients, since knowledge of their effectiveness in this matter is poor. In 2003 a wetland was constructed on an old meadow on the western shore of Lake Bornsjön in central Sweden. The main purpose of the wetland was to reduce the amount of phosphorus entering the lake, which is the back-up water supply for Stockholm when the city cannot obtain water from Lake Mälaren. Large areas around Lake Bornsjön consist of agricultural land and the nutrient concentrations in the inflows to the lake are usually relatively high (approx. 1 mg/l total nitrogen and 0.05-0.1 mg/l total phosphorus).

ICC-profilers duglighet vid gråbalansjustering av arkoffsettryck

Adjustment to a neutral colour balance when printing was the starting point in this degree project. Onthis base ICC-profiles were evaluated and assessed. The survey was concentrated on the similarity betweenreproductions on different papers with various ICC-profiles. The colour balancing introduced aconsistent variable between four graphic papers. With raised uniformity the probability increased toreceive similarities between the various combinations of ICC-profiles and papers.Numerous of measurements and calculations have been carried out, mainly to confirm whether or notadjustment to a neutral colour balance is possible and repeatable.

Elasticitetsmodulen i en kalkstabiliserad vägterrass : en fältstudie

Stabilization of subgrade is an internationally common technique to improve the characteristics of a soft soil. Improving the stiffness and bearing capacity of the subgrade enables the pavement to be designed with reduced depths of subbase and basecourse aggregates. This makes the stabilization technique both economically and environmentally interesting. Both natural and stabilized soils have high inherent property variability that should be considered when the characteristic value is derived. By analyzing the spatial variability in stabilized and natural subgrades it is possible get the parameters needed for reliability?based modeling of soil properties.
