Ultraviolet Spectral Analyses of HgMn Stars

Almost a decade after the last observations were performed by theInternational Ultraviolet Explorer (IUE) satellite its rich archivescomprise a wealth of opportunity for the stellar astronomer, inparticular when exploring large samples of stars. We have inaugurated anexploration into the nature of chemically peculiar stars through thoseelemental abundance studies which are best carried out at UVwa

Overview of vehicle-to-vehicle radio channel measurements for collision avoidance applications

In this paper we present an overview of a vehicle-to-vehicle radio channel measurement campaign at 5.6GHz. The selected measurement scenarios are based on important safety-related applications. We explain why these scenarios are interesting from the aspect of radio propagation. Further we describe the power-delay profile and the Doppler spectral density of two situations especially suitable for co

The importance of predation in benthic stream communities

There has been considerable debate whether or not predators has any significant effects on prey densities in streams. This thesis examines the importance of predation in stream communities. I have conducted both field and laboratory studies where I have studied how both vertebrate and invertebrate predators affects benthic prey. Generally, predators have been found to have strong negative effects

Evolution of a Negatively Buoyant Jet in the Near and Intermediate Field

The most common situation connection with freshwater production from sea water (desalination) is producing a brine waste stream, usually discharged back into sea water. The purpose of this study is to explore the behavior of a dense jet and bottom plume, composed of brine water of heavier effluent into a quiescent homogeneous ambient, discharged into a receiving body of lighter fresh water (tank).

The Exchange-Value of Solar Thermal Energy

In Sweden there is a tendency that alternative energy will develop on market premises. In this paper I suggest that the low exergy value of solar thermal energy limits the technique's commodification, i.e. the possibility of having a commercial exchange-value on the market. Anthropologists argue that value of a commodity has to be related to social and cultural aspects of the society where it is s

Computer-Aided Planning of Working and Living Environments for Disabled People

A research program for the development of a method for computer-aided planning of homes and working environments for disabled people has recently started. The method is being tested at rehabilitation centres in realistic planning situations and has obtained positive response from both the disabled persons and the professionals such as occupational therapists. The requirements and features of the c

Successive interference cancellation in multistream faster-than-Nyquist signaling

In earlier work we have extended Mazo's concept of faster-than-Nyquist signaling to pulse trains that modulate adjacent subcarriers, a method we called two dimensional Mazo signaling. The signal processing is similar to orthogonal frequency division multiplex (OFDM) transmission. Despite pulses that are faster than the Nyquist limit and subcarriers that significantly overlap, the transmission achi

Tolkningen av Bibeln i Karl XII:s bibel

Bibeltolkningen som kommer till uttryck i Karl XII:s bibel, i dess register, summarier och förklarande noter, kan sägas vara helt präglad av en luthersk-ortodox uppfattning med viss distans till Luther själv. Polemiken är tydlig emot romersk-katolsk och kalvinsk teologi. Pietistiskt inflytande märks inte men inte heller polemik emot pietismen.
