By virtue of their geometry, uniform circular arrays (UCAs) are ideally suited to provide 360 degrees of coverage in the azimuthal plane. However, in a correlated signal environment, the well-known technique of spatial smoothing to mitigate the signal cancellation effect as seen in an optimum beamformer will not work since this technique is applicable only to uniform linear arrays. We show how the

The point of departure of the dissertation is crime committed when doing cross-border transactions concerning otherwise legal products. The crimes in focus are such which can be described as more organised than everyday crime – but not as organised as required by the widely used and discussed concept of organised crime. From there, a discussion, based on criminal politics, criminal law, crime and

We present an approach and examples of design artefacts from on-going work on how children with profound disa-bilities can participate in formative design processes. It involves the pedagogical use of digitally interactive mul-tisensory environments. Rather than mimic participatory design from more symmetrical contexts, we address po-tentials in the situation at hand as well as the key issues of v

Various biological problems such as disease mechanisms, drug development and toxicological studies motivated the introduction of cellular models that today also represent an alternative for reducing the use of animals in controversial medical and pharmaceutical experiments. Cells are complex matrices where several processes occur simultaneously. Because of this, analytical methods with specific p

We consider a window decoding scheme for Braided Convolutional Codes (BCCs) based on the BCJR algorithm. We describe the principle of this decoding scheme and show that BCCs with window decoding exhibit excellent performance. The tradeoff between performance and decoding latency is examined and, to reduce decoding complexity, both uniform and nonuniform message passing schedules within the decodin

Vehicle-to-vehicle (VTV) wireless communications have many envisioned applications in traffic safety, congestion avoidance, etc., but the development of suitable communications systems and standards requires accurate models for the VTV propagation channel. This paper provides an overview of existing VTV channel measurement campaigns, describing the most important environments, and the delay spread

Popular Abstract in Swedish Det är välkänt att utflödesobstruktion kan leda till förstoring av blåsan med åtföljande minskning av kontraktionskraften, något som kan påvisas både in vivo och in vitro. I arbete I undersöktes därför om det fanns regionala skillnader i blåsmuskelfunktion hos kaniner med experimentell utflödesobstruktion. Efter 2 veckors obstruktion utfördes cystometri och därefter undThe consequences of bladder outlet obstruction (BOO) with respect to detrusor hypertrophy, structural and functional changes, and obstruction-induced detrusor overactivity were investigated in vivo and in vitro utilizing various animal models. Possible pathophysiological pathways and therapeutic approaches were tested by drug treatment and the use of knockout models. Furthermore the role of estrog

In ad hoc mobile networks nodes typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper evaluates a solution that allows mobile nodes to access the wired Internet and roam from base station to base station. The solution is based on the extension of Mobile IP capabilities to t

The paper explores motivational and cognitive effects of more neutral or androgynous-looking characters versus more feminine-looking female and masculine-looking male characters. A user study involving 158 students, aged 17-19, encountering four virtual characters, visually manipulated to represent gender stereotypicality versus androgyny, is presented. On the one hand we explored students’ attitu
