In the vehicular communication channels, the mobility of the receiver (RX) and the transmitter (TX) along with the movements of interacting objects in the propagation environment result in significant non-stationary channel fading. The channel impulse response exhibits not just significant delay- and Doppler spreads, but also the delay- and Doppler spreads themselves are changing over the time- an

A summary and evaluation of perceptgenetic research over the last half century

There is general consensus among road safety researchers that the crash count is not linear with respect to the traffic volume. However, the now-preferred practice of estimating exponents on traffic volume not only results in parameters that cannot be confidently applied in other contexts, but also offers very little insight into the relationship. This paper describes a preliminary investigation o

We have evaluated capacitive and thermal transducers for recognition of bio- molecular interactions with different analytes. These assays were made in flow analysis systems because of the simplicity such methods provide. A capacitive transducer, based on a surface modified gold electrode, has the ability to monitor affinity based interactions directly, provided that the interactions introduce mea

Gangliosides (G) are sialic acid-containing cell surface glycosphingolipids capable of forming lactones, i.e. inner esters. Some gangliosides are tumor-associated antigens, and they may serve as immunogens in their lactone form, where the latter is comparatively more abundant on the surface of malignant cells. Due to improved hydrolytic stability, lactam (inner amide) analogues of gangliosides sho

Mitochondrial permeability transition (MPT) is induced in isolated brain mitochondria by calcium and oxidants and is inhibited by adenine nucleotides. When induced, MPT is associated with equilibration of solutes of

In this paper we estimate the opportunity cost of children. The underlying theoretical model is represented by a household production model. In the empirical analysis, we consider three different cohorts for men and women born between 1955 and 1970. For the women in the two oldest cohorts, the opportunity cost of two children is estimated to 28-29 per cent of full income, which in monetary terms i

Fuel cells are promising for future energy systems, because they are energy efficient and able to use renewable fuels. A fully coupled computational fluid dynamics (CFD) approach based on the finite element method (with the software COMSOL Multiphysics) in two-dimensions is developed to describe an intermediate temperature solid oxide fuel cell (SOFC) single cell. Governing equations covering heat

Popular Abstract in Swedish Att förstå mekanismen som bestämmer djurs beteende är inte lätt. Genom att studera beteendet hos enklare djur kan man göra det mer förståeligt. Om man vill studera ljusstyrt beteende är det enklaste djuret att använda en manet från karibiska området vid namn Tripedalia cystophora. Denna manet har ögon som liknar människans ögon. De lever i vattnet i mangroveskogar och äMost animals use eyes to guide their behaviour. Analysing, and understanding, visually guided behaviours gets more complicated the more advanced the animal gets. Box jellyfish provide a relatively simple system for understanding visually guided behaviours. They have a limited nervous system, but they also possess a visual system that is quite impressive for a jellyfish. Box jellyfish have 24 eyes
