Visible and radar observations of the Perseid meteor stream 1953-83

This paper describes a long term, high-resolution study of the activityof the Perseid meteor stream based on visual and radar observations atthe Onsala Space Observatory in Sweden. The data consists of 147 visualhourly rates and 1368 radar hourly rates. In a previous paper (Lindblad2000) a high-resolution study of the visual zenithal hourly rates ofbright Perseid meteors versus solar longitude was

Nya Vägar: Report on the Nya Vägar Seminars on "Striving -- Jihad -- against social exclusion: New Ways of tackling discrimination through co-operation among Christians, Muslims, and other organisations"

Detailed report on five seminars held in Malmö and Leicester, exploring ways in which Christian, Muslim, and secular groups work together in multicultural contexts, using dialogue as a means of effective "striving/Jihad" against social discrimination and exclusion. Includes reflections by the Christian and Muslim authors

The Role of the Electrodes for the Ionization Sensor Signal

The effect of the electrodes on the early signal of the ionization sensor has been studied experimentally and with a model for the sensor. Experiments in a constant-volume combustion chamber with a generic electrode configuration allowed to investigate the role of electrode contact and the main path of the current. A framework for a model allowing the inclusion of electrode processes is introduced

Analytic prediction of electromagnetic behaviour

The amount of electrical loads and the complexity of the electric system in a vehicle is increasing at the same time as the allowed development time is getting shorter. Possibilities to predict the electromagnetic behaviour is therefore of great importance. In this paper, a method for determining the parasitic components affecting crosstalk in a cable harness is proposed. The method suggests that

Contextual Inquiry and Requirements Shaping

A primary purpose of traditional systems analysis is seen as ‘capture’ or ‘elicitation’ of user requirements, in order to produce specifications as a basis for information systems design. Such a view presupposes that user requirements are pre-existing and clear, and that the particular ‘users’ concerned know what they are, and can therefore articulate them. We would argue that none of these assump
