Produktion av marknadsförings- och korrespondensmaterial för DUCIS

The report describes the production of graphic correspondence and marketing material for DUCIS(Dalarna University Centre for Irish Studies).A logotype symbol is created on the basis of an element from the Celtic art, and a graphic material thatharmonies with this ideal of style is built around the symbol. A unique visiting card, correspondence cardand letterhead is produced to strengthen the identity of DUCIS outwards.The work proceeds with an international education folder which is an important element in the marketingwork for the MA-education which starts in the autumn of 2003. Two posters, one for the opening ofDUCIS in may 2003 and one for a conference in 2004, are produced. Finally, a redesign of the book coverfor NIS, Nordic Irish Studies, is carried out.The report describes the working process consisting of meetings, practical work and other elementswithin the process. The conclusion is that the work has been quite successful and that this, to a largeextent, depended on an engaged and supporting commissioner. The commissioner also is very satisfi edwith the results.The in-depth studies of the project is about the art and design of the Celtic culture throughout history.The text gives an account for the history and expressions of Celtic art from its birth, 2800 years ago, untilits death in 13th century Ireland and Scotland. Special attention is payed to the golden age of ChristianCeltic art on the british islands, the era from which the pattern of the DUCIS logotype originates.

European Solar Engineering School ESES : Past and Future

The European Solar Engineering School ESES is a one-year masters program that started in 1999 at the Solar Energy Research Center SERC, Dalarna University College. It has been growing in popularity over the years, with over 20 students in the current year. Approximately half the students come from Europe, the rest coming from all over the globe. This paper described the contents and experiences from seven years of running the programme and the plans for adapting the programme to the Bologna process. The majority of the students from ESES have found work in the solar industry, energy industry or taken up PhD positions. An alumni group has been started that actively gives support to past, present and potential future students.

Asymmetrical awnings : a way to increase daylight in buildings without increasing the overheating

Different shapes of asymmetric awnings for east and west windows are investigated mathematically as well as by measurement in a model. A box with 90 cm side and a 30x30 cm window was placed outdoor in overcast weather and the daylight factor was measured at the bottom of the box when the window was unshaded or equipped with different awnings. The average daylight factor in the box decreased from 4.6% for the unshaded window to 1.0% when a full awning was used. With “the best” asymmetrical awning, the average daylight factor was 80% larger than with the full awing. Using Dutch climate, calculation of the energy from direct radiation transmitted through the window during the cooling season showed that this was decreased from 100% as an annual mean for the unshaded window down 22% with a full awing. With “the best” asymmetrical awning, 26% of the energy was transmitted. Calculation of the indoor temperature in a hypothetical row house in Netherlands show that the use of either normal or asymmetrical awnings considerable decrease the indoor temperature during the hot season. Therefore the use of asymmetrical awnings for east or west faced windows considerable can increase the daylight in buildings, with almost no change in overheating, compared to if traditional awnings are used.

Detecting Plants on Railway Embankments

This paper investigates problems concerning vegetation along railways and proposes automatic means of detecting ground vegetation. Digital images of railway embankments have been acquired and used for the purpose. The current work mainly proposes two algorithms to be able to achieve automation. Initially a vegetation detection algorithm has been investigated for the purpose of detecting vegetation. Further a rail detection algorithm that is capable of identifying the rails and eventually the valid sampling area has been investigated. Results achieved in the current work report satisfactory (qualitative) detection rates.
