Optimering av OTEC-system
Ocean Thermal Energy Conversion, OTEC, is a sustainable energy conversion technology that is not yet commercialized. OTEC is a technology that utilizes the temperature difference in oceans between the warm surface water and the cold water at 1 000 m depth to run a Rankine Cycle. This technology can produce electricity and provide synergies like fresh water, air conditioning and aquaculture. A simulation program for three alternative OTEC systems has been created in order to decide which OTEC system is most profitable; closed, open or hybrid system. In this simulation a production cost analysis is performed in order to investigate and decide which one of the three systems that has the lowest production cost. The production cost analysis also analyzes if the profitability is affected by the size of the facility. After these analyzes, the most profitable of the three different OTEC-systems is expanded by an installation of solar collectors in order to see if the thermal efficiency is improved. The result shows that the most profitable system varies with the size of the facility.
Uppvärmd konstgräsplan : Beräkning av utnyttjningstid för en uppvärmd konstgräplan med alternativa rörplaceringar
For Skattkärr IF a turf field with warming has been projected to increase field?s utilization hours and to have a longer period for athletes to perform their activities outdoors. The technique chosen to heat the plan is a type of a geothermal heating system without a heat pump. The brine, which is water with 30% ethanol, collects heat from the borehole and discharges it to a coil in the field. There is at position 11 boreholes but it is planned to increase the number to 31, which is the design for the facility.
Mobilapplikation för träning av häst
De allra flesta som tränar hästar gör det för att i något syfte öka hästens prestationsförmåga. När hästen är rätt tränad för sin uppgift minskar skaderisken hos både häst och ryttare. Rätt träning främjar hållbarheten på lång sikt. Med en pulsmätare anpassad för användning på häst är det möjligt att utläsa vilken intensitet träningen har och anpassa den för att få den effekt man önskar. Med konditionstest för häst kan man sedan utvärdera om träningen haft avsedd effekt.
En enkel mobilapplikation anpassad för konditionsträning av ridhäst skulle kunna leda till en ökad medvetenhet kring träning och träningsintensitet hos människor som tränar ridhästar.
Situationer och varumärkeslojalitet : Hur återkommande köp- och konsumtionssituationer är kopplade till konsumenters varumärkeslojalitet
The thesis focuses on the measurement of situational factors affecting brand loyalty in purchases and consumption. A survey is conducted using previously developed scales and 199 respondents. Results show that for the particular product category (ready-to-drink recovery drinks), purchase frequency and the product experience have stronger effects on loyalty than do situational factors such as type of activity and perceived stress. Implications for managers are discussed and suggestions for further research is presented..
Gäddfisketuristerna : En kartering och marknadssegmentering av de Europeiska marknaderna för gäddfiskande turister i Sverige
This investigation indicates that there are regions within Europe that seems to have similar preferences and priorities regarding pike angling travels to Sweden. Swedish pike angling facilities process in first hand markets with favourable economic circumstances and a cultural interest for pike angling. There was a big differences in features between the Northern, Western, Eastern and Southern regions of Europe. They also seems to be tied to specific regions within some of the nations.The regions have diverse requirements and distinguish in terms of consumption and preferences regarding different aspects of pike angling. From there it is possible to divide pike angling tourists into segments.
