Marine transportation in EU currently emits 18% of the total global marine CO2 emissions, which is approximately 140 million tonnes of CO2. In response to this, new regulations aim to reduce carbon emissions by 40% by the year 2030, therefore, green innovations in marine technology are more important than ever. However, reducing carbon emissions requires people to accept these new technologies. In this paper, I explore the role of human-centred design in technology acceptance by using some methods in the design process. The design process included various methods such as user-, heuristic evaluations, expert reviews, role-playing, parallel prototyping, and prototyping. I studied, evaluated, and redesigned the interface of EcoPilot, that is a product which calculates, decreases, and optimizes fuel consumption in marine transportation. The design process of EcoPilot resulted in increased knowledge about the current user experience of marine technology aimed at reducing carbon emissions, as well as conclusions and reflections on how human-centred Design can improve the experience and promote the acceptance of new green technology.

Being inconspicuous in the dark outdoors can cause accidents including physical injuries. To prevent pedestrian being involved in accidents it is necessary to make them most visible to approaching people.This Master’s Thesis examines the use of retroreflective clothing in a semi-dark urban environment to provide safety through conspicuity. Through analysing the lighting situation in Stockholm, the ability of the human vision, reactions and existing products it has led to experiments and surveys to find the most efficient line placement and pattern to make an individual recognizable as human on approach.The results were that body outlines and horizontal lines along joints made a human most identifiable. Most conspicuity was given when lines were wider than 2cm and patterns contrasted to the surroundings.As the experiment was conducted in a semi-dark setting, different retroreflective design solutions might be more adequate for other lighting scenarios with more or less light

Examination concerning the possibility of finding prehistoric children as considerable actors through the medium of neolithic clay figurines which were discovered in the archaeological remains regarding a pitted-ware settlement excavated in Tråsättra, Stockholm parish in the year 2016. The main aim for this study is to pay attention to a group of individuals most often overlooked in archaeological research as a whole, by searching to find new angles of incidence in a material previously interpreted from a ritual perspective.

Estimates of abundance are critical to manage and conserve waterfowl and their habitats. Most surveys of wintering waterfowl do not use probability sampling; therefore, development of more rigorous methods is needed. In response, I designed and evaluated an aerial transect survey to estimate abundance of wintering ducks in western Mississippi during winters 2002?2004. I designed a probability-based survey using stratified random and unequal probability sampling of fixed-width transects. To correct for visibility bias inherent in aerial surveys, I conducted an experiment to model bias and incorporated correction factors into estimation procedures to produce adjusted estimates. Bias-corrected estimates were most accurate. Precision of abundance estimates of total ducks met a priori goals (CV ≤ 15%) in 10 of 14 surveys. Based on a simulation study, the implemented survey design provided the most precise estimates, yet certain refinements remained possible. I also illustrated potential applications of survey results in the context of conservation and management of wintering waterfowl populations and habitats. I described patterns of abundance within and among winters, including a comparison with surveys conducted during winters 1988?1990 that revealed mallard abundance decreased 65% from the late 1980s. I developed a method to illustrate population abundance spatially for scientific and public education. I attempted to explain temporal variation in abundance estimates relative to variables potentially representing hypotheses explaining regional distributions of ducks. I concluded the data provided stronger support for factors related to energy conservation by ducks than factors related to energy acquisition. Finally, I determined associations between duck distributions and habitat and landscape features in accordance with the habitat-complex conceptual model. Landscapes with greater interspersion and diversity of wetlands attracted increased numbers of ducks, a though other factors such as wetland area also were important. I concluded that this study advanced methodologies to survey wintering waterfowl. Although improvements were warranted, I recommend this survey design for continued monitoring of wintering ducks in western Mississippi. Furthermore, I suggest habitat management on public and private lands should include complexes of seasonally flooded cropland, moist-soil, forested, and permanent wetlands to potentially increase wintering duck numbers in western Mississippi.

The capital of Germany Berlin will undergo a change in its skyline in the next few years.Due to a new housing policy that allows the construction of higher buildings, Berlinwill soon have several skyscrapers over 130 m high directly at Alexanderplatz as wellas next the Berlin landmark, the Berlin TV Tower.With the help of ArcGIS, the newbuildings are shown in 3D along with the impact of these buildings on the view to theTV Tower and the shadows cast by the new buildings on the Alexanderplatz. It is shownthat due to the new buildings, some areas around the Alexanderplatz no longer have acomplete view to the TV Tower. The shadow cast by the buildings will only slightlychange the current shadow cast on the Alexanderplatz, but neighbouring areas aroundthe Alexanderplatz will now be affected more by shadows.
