I bronsålderns gränsland : Uppland och frågan om östliga kontakterOjala, Karin January 2016 (has links)
In archaeological research, the province of Uppland has often been viewed as the northern ‘periphery’ of the Nordic Bronze Age region. At the same time, many researchers have also emphasized the distinctive and ‘independent’ regional character of Uppland and northern Mälardalen. Throughout the twentieth century, Late Bronze Age contacts between Uppland and areas to the east – especially Finland, the Baltic countries and Russia – were much discussed and played an important role in the creation of Mälardalen as a distinctive Bronze Age region. This dissertation examines how images of the Late Bronze Age in the Mälardalen region, more specifically Uppland, have been formed from the late nineteenth century until today, and how views on eastern contacts have affected interpretations of Bronze Age Uppland. The study consists of three parts: 1) A critical discussion on political dimensions of archaeology and archaeological concepts of contact, interaction, similarity and difference, with a special focus on Bronze Age research. 2) A historical examination of representations of the Late Bronze Age in Mälardalen and Uppland, including a discussion about contacts with northern Sweden and a case study of Broby, a Late Bronze Age site near Uppsala. 3) An analysis of debates on contacts between Mälardalen and areas further to the east, through case studies of bronze axes, so-called Mälar celts and Ananino celts, ceramics and inhumation burials. In the analysis, special focus is placed on the Volga-Kama region in Russia and archaeological research in Russia and the Soviet Union. The study shows that discussions on contacts and interaction between ‘East’ and ‘West’ have, in many ways, been affected by the changing political situation during the twentieth and early twenty-first centuries. Knowledge about archaeological research in Russia and the Soviet Union has been very limited among archaeologists in Sweden. In order to further investigate the character and importance of eastern contacts during the Late Bronze Age, more collaboration and exchange between researchers in the different countries is needed. Furthermore, in order to better understand eastern contacts, it is also necessary to investigate in greater depth the relations between Mälardalen and northern Sweden.

User Interface Design of Head-Up Display Using Scenarios : An Early Stage Innovation Project at Bombardier / Användargränssnittsdesign av head-up-display : - En tidig fas i ett innovationsprojekt vid Bombardier TransportationAgarwal, Rohit January 2018 (has links)
Head-up display (HUD) är en beprövad teknik inom flyg och bil, vilken gör det möjligt för piloter och förare att få tillgång till information utan att uppmärksamheten avleds från omvärlden. Liknande fördelar kan uppnås genom installation av HUD i tåg. Syftet med denna studie är att utveckla ett användargränssnitt för HUD baserat på European Rail Traffic Management System (ERTMS). HUD kommer att vara en extra säkerhetsfunktion för tågen för att förhindra förare från att skifta fokus mellan instrumentpanelen och omgivningen, vilket leder till minskad förareutmattning och bättre observation av spåren framåt. Scenario Based Design-metoden har använts för att genomföra projektarbetet och i rapporten diskuteras metodens fördelar och begränsningar. Användningen av scenarier har gjort det möjligt för designteamet att på djupet förstå de situationer som förarna står inför samt har hjälpt till att under workshops få en bättre förståelse för drivrutinerna. Dessutom har rekommendationer för hårdvara, installation och framtida arbete beskrivits för fortsatt genomförande av projektet. / Head-up display (HUD) has a proven track record in the aviation and automobile sectors, allowing pilots and drivers to access information without diverting attention from the outside world. Similar benefits may be realized by the installation of HUD in locomotive cabs. The objective of this thesis work is to develop the user interface for HUD based on the ERTMS system. The HUD will be an added safety feature to the trains to prevent drivers from refocusing between the instrument panel and the outside view thus leading to reduced driver fatigue and better observation of the tracks ahead. Scenario Based Design method has been used to implement the project work with discussions regarding its advantages and limitations. The use of scenarios has allowed the design team to understand the scenarios that the drivers face in depth and has aided during the workshops to understand the drivers’ routine better. Additionally, recommendations for the hardware, installation and future work have been provided to support further implementation of the project.
