På ingenjörsutbildningar får studenter fördjupa sina kunskaper i programmets senare del i form av specialinriktningar eller valbara kurser. Detta är något som inte är tillgängligt för studenter som läser till sjöingenjör vid Sjöfartshögskolan i Kalmar men något som infördes på sjöingenjörsutbildningen vid Chalmers Tekniska Högskola 2009. Studiens syfte är att undersöka intresset för valbara kurser på 7,5 högskolepoäng (hp) vardera för sjöingenjörsstudenter vid Sjöfartshögskolan i Kalmar. En enkätstudie svarade på frågorna om vilka ämnesområden som var av intresse, hur många kurser eleven ville läsa, när under utbildningen önskas kursen läsas, om intresset för valbara kurser saknas och i så fall varför. Resultatet av undersökningen visade att de ämnesområden som är av störst intresse för studenterna på grundnivå är offshore/oljerigg och landkurser.

In January 2005 large forest areas in south Sweden were severely damaged by storm. This final thesis describes the work with creating an ecological and landscape-adapted regeneration plan for a severely storm damaged property in Kronobergs region in south Sweden. This regeneration plan, in difference to more regular plans, are focusing more on the owner?s use and goal?s for the property and seeing the property from a more comprehensive view in the regeneration process. Beside production and environmental values the plan also take in consideration other values as aesthetic, culture history, landscape picture and recreation values.

Nordic Marine Sauna AB has, since 2005, designed, manufactured and sold floating saunas. Theproduct are characterised by a well thought thru and appealing design and its high quality. Thecompany is now intending to open a new business area by starting a subsidiary, NordicSubmarine Sauna AB, which will design submerged saunas. The expected customers are leisureand conference centres as well as customers that seek an experience out of the ordinary.Due to the products technical complexity a master thesis was adverted. The task was to do aninvestigation whether such a product is technically viable.The job involved research of existing products and constructions material as well as designingthe product with CAD and FEM-programs.

This thesis has been carried out within the bachelor program for mechanical engineering at Karlstad University in collaboration with BAE Systems in Karlskoga. The purpose with this work was to design a mechanism and associated parts for loading and unloading of shots between primary and secondary magazine in BAE's new 40mm's ship gun.Parts designed or redesigned among other things a transfer mechanism for shot at loading and unloading, well as a hatch mechanism which makes the shots do not fall out of the primary magazine when making separate use. Various important details have been designed to maintain a good functionality of the mechanism.The construction work has mainly been carried out in the CAD software Solid Edge and its associated FEM module. The construction work has also been carried out on rough calculations for constructed details in order to ensure that they meet the stringent requirements of military use in tough marine environment. Two of the most critical parts of the structure where analyzed with the FEM module for estimating the stresses in the material at the applied load.The final design, which is a result of the thesis, meets the requirement specification and the set targets.

On the 1st of January 2014, new legislation was introduced on taxation of shareholders in close companies. The legislation has faced criticism from several of the respondents and the purpose of the master?s thesis is to critically examine the legislative amendments made. The base of the thesis is to present the legislation within taxation of shareholders in close companies, to examine the purposes and motives of the legislator and the criticism received for the legislative amendments, as well as provide a historical perspective of the purpose of the rules. An analysis of the incentives that the legislator is providing shareholders in close companies, with the amendments, and the extent to which they reflect the purpose of the legislation.

Man?s impact on the environment is something that increasingly becomes topical in today?s society. Because of this, several companies have started to take interest in the effects they?re responsible for, not least considering their image. Emissions of carbon dioxide generated from goods traffic are accountable for a large part of the total emissions of greenhouse gases in the world.

Beslutsfattande är den viktigaste av alla ledningsaktiviteter. Syftet med denna studie är att undersöka hur befälhavare upplever beslutprocesserna ombord och i den omgivande organisationen. Undersökningen har gjorts genom intervjuer med tre befälhavare. Intervjuer valdes för att kunna lyssna till intervjupersonernas upplevda värld och de har varit semistrukturerade, som stöd har en intervjuguide använts. Det går i den här formen att följa trådar eller infall men också att gå tillbaka och förtydliga.

Den statliga sjöfarten idag är ett område med många inblandade myndigheter och en oklar uppgiftsfördelning. Det är även svårt att se hur väl organiseringen av den statliga sjöfarten är uppbyggd för att klara en kris eller ett krig. Syftet med uppsatsen är att undersöka hur effektiv den statliga sjöfarten är vid en kris, hur väl kraven för maritim säkerhet uppfylls och hur försvarsmaktens roll i den statliga sjöfartenI formen av en fallstudie med en teoretiskt deduktiv ansats och en kvalitativ textanalys appliceras Graham Allisons organisationsteori och teori om maritim säkerhet på den statliga sjöfarten. Empirin är i form av förordningar, instruktioner och reglerbrev som är ställda på respektive myndighet.Undersökningen visar att dagens organisering av den statliga sjöfarten inte är optimal för att verka vid en kris och kraven för maritim säkerhet uppfylls, men förbättringspunkter föreligger. En slutsats är att en närmare samverkan mellan myndigheterna skulle lösa många av de problem som idag existerar.

Sheep breeding contributes not only with wool, hides, meat and milk but also with openlandscapes. The sheep?s wool is a good raw material thanks to a lot of different qualities as itis water rejecting and easy to form. The wool production today is concentrated to specificplaces in the world which leads to environmental problems and a distorted market. InJämtland, a province in Sweden, there is right now a staking going on for local production andrefining of wool in a project called Ullforum.

Until 2020, 49% of Sweden's use of energy must derive from renewable sources. Greenhouse gases must as well decline with 40% compared to 1990 as a part of Sweden's 16 environmental objectives. Biogas is part of the effort to achieve these objectives, but as the demand for biogas increases, more substrates are needed to meet the demand. The purpose is to investigate the conditions for pea residue as substrate by performing lab-scale mesophilic digestion with different fractions and notch lengths and then to summarize pea residue as a substrate for biogas production. During anaerobic digestion, 1000 ml bottles were used as reactors for digestion.

Today, the catering personnel are an essential part of the safety organization on board Swedish passenger vessels in ferry services. Their responsibilities for the safety on board have increased in connection with the changes in regulations made on the shipping industry. These changes have been mostly related to human factors and structural leadership in the last 25 years.A well-functioning safety organization requires competence and commitment from every individual. Previous researches on Swedish passenger ferries concerning the safety organization have raised issues regarding the catering personnel?s perception of the safety on board.

The purpose of this thesis is to develop an application for mobile phones that simplifies communication. The company Doberman wanted to look at possibilities to develop such an application that uses Bluetooth? technol-ogy to communicate in ad-hoc networks. The aim has been an application to run on mobile phones in which you can send messages and files to other devices and also add a user profile with personal information to share with others. The communication will take place in temporary networks created when Bluetooth enabled devices is in range of each other.The market for mobile phones has grown rapidly over the past years and is still growing.

The purpose of this thesis was to examine how locally produced bioenergy may contribute to meet the climate target year 2050 in the municipality of Uppsala. The goal of reduced GHG-emissions from current 6,8 ton CO2-equivalents to 0,5 ton CO2-equivalents per capita and year, year 2050 is based on avoiding harmful penalties of an increased level of GHG in the atmosphere. By estimating available biomass in the county together with examining future technologies and emission factors for the substrates used, four possible future scenarios has been developed focusing either on electricity generation or production of biofuels. GHG-emissions of year 2050 have been calculated using the software LEAP. The conclusion is that bioenergy, depending on how it is integrated in the energy system, may reduce greenhouse gas emissions between 0.6 ton CO2-equivalents and 1.4 ton CO2-equivalents per capita or 12% to 25% compared to 5.5 ton CO2-equivalents in the reference scenario 2050. The greatest reduction is obtained if biofuels are produced in combination with energy efficient heat requirements in buildings..

This report is made as a literature review, focusing on the work done to increase understanding of efficiency in the categories of substations and secondary heating systems, with respect to the deviation from the theoretically possible cooling off in the distribution network as well as the economic benefit that appear. The main purpose of a considerable part of the literature used in this report addresses the issue of identifying individual causes of reduced cooling in district heating systems. These literature resources have been compiled and summarized as part of the report.The technology of district heating is associated with benefits such as better use of the energy in a fuel. This is the case of cogeneration plants where serial generation of electricity and thermal energy increases efficiency compared with the parallel generation where heat is generated locally and electricity is generated centrally. Serial generation thus allows for lower primary energy demand.
