Drönares praktiska tillämpning för leveranser till fartygCederlöw, Jonatan January 2022 (has links)
Studien undersöker i vilken mån man kan anpassa drönares funktion till leveranser av varor till fartyg i form av intervjustudier. Arbetet berör den ekonomisk vinning jämfört med de provianteringsfartyg som annars genomför denna transport samt de aspekter som handlar om drönaroperatörens inverkan på denna typ av tjänst. Undersökningen resulterade i att drönaren kan användas som komplement och att tekniken som finns på marknaden är tillräcklig för att på ett säkert sätt kunna genomföra leveranser till fartyg med drönare som hjälpmedel. Vidare visade studien att enligt de intervjuade drönaroperatörerna är det fortsatt oklart i vilken utsträckning som drönaren kommer kunna tillämpas då få drönare finns som är skräddarsydda för detta specifika ändamål men att det ses fortsatt positivt på implementeringen utav drönare som verktyg till sjöss. / The purpose of this study aims to investigate the extent to which the function of drones can be adapted to deliveries of goods to vessels. This study was conducted in the form of interview studies. The study concerns the economic gain of supply deliveries with drones compared to the provisioning vessels, that otherwise carry out this payload as well as the aspects that deal with the drone operator´s impact on this type of service. The study concluded that the drone can be used as a complement and that the technology available on the market is sufficient to be able to safely carry out these deliveries to vessels using drones as aids. Furthermore, the study showed that according to the interviewed drone operators, it is still unclear to what extent the drone will be applied as there are few drones that are tailored for this specific purpose, but that the implementation of drones as a tool at sea is still viewed positively.

Caring for lhuq'us (pyropia spp.): mapping and remote sensing of Hul'qumi'num culturally important seaweeds in the Salish SeaBaker, Jack 25 September 2020 (has links)
Hul’qumi’num communities on south eastern Vancouver Island have concerns about the status and safety of marine foods potentially impacted by environmental change and the urbanization and industrialization of their territories. Collaborative research undertaken with the Hul’q’umi’num’ Lands and Resources Society is part of a broader effort to revitalize cultural practices, language, and food systems. Lhuq’us (the Hul’q’umi’num’ language term for pohrpyra/pyropia spp. (commonly known as red laver or black gold)) is a flavourful and nutritious intertidal seaweed that grows on rocky beaches across the Pacific Northwest. Hul’q’umi’num’ language, cultural values, teachings, and family histories are all interwoven into the harvesting and consumption of lhuq’us in Hul’qumi’num territories. Lhuq’us is one of the species that have been persistently mentioned in conversations with state regulatory agencies and though these concerns have been raised for at least two decades there has been no systematic monitoring of the species. There are two broad streams of inquiry taken by thesis thesis. The first, employing ethnographic methodology including interviews and observant participation, seeks to both document the cultural values, oral histories, lived experiences associated with lhuq’us as well as concerns for the future collaborators have for lhuq’us and lhuq’us beaches. The second stream, based in a geographic approach, asks whether Unoccupied Aerial Vehicle (UAV) technologies could be employed to record the status of lhuq’us as a baseline for monitoring. Two study sites in the Salish sea were surveyed using UAV techniques: ȾEL,IȽĆ and St’utl’qulus. The overall accuracies of the UAV imagery classifications and the particular accuracies of the class representing lhuq’us suggest that UAV technologies paired with Google Earth Engine (GEE) object based image analysis (OBIA) methodologies can effectively detect lhuq’us. There are serious concerns and cultural values and practices deeply interconnected with culturally important species like lhuq’us. Through holding these concerns and values side by side with systematic observation and analyses maps and materials were created which communities can use to assert their rights, enact their own monitoring of territories and re-prioritize environmental decision-making done by federal, provincial, and municipal management agencies. / Graduate
