Time Domain Characterization of Circular Polarization Selective Structures

This paper investigates how typical frequency domain concepts such as circular polarization and axial ratio can be given a useful meaning in the time domain. The relationship between the linear polarizations of a circularly polarized time dependent signal is shown to be the Hilbert transform, and the instantaneous axial ratio can be computed from envelope functions, obtained from corresponding ana

Biologisk psykologi

Den biologiska psykologin har under senare år, tillsammans med andra vetenskaper som rör hjärnan, utvecklats till ett mycket aktivt och framgångsrikt forskningsområde. I detta kapitel kommer vi ofta att röra oss i gränsområden till andra vetenskaper - som utvecklingslära, genetik, neurofysiologi och neurokemi - för att presentera en karta över detta expansiva område.

Governance as a process for strategy development – Collaboration in jointly owned local government organizations

In Sweden, municipalities organize a large share of public services but the conditions for providing these services differ considerably due to differences in size and wealth. In the wake of financial stress and New Public Management reforms the Swedish local governments seeks new ways to make both ends meet and still manage the services to be in line with the present (not the past) demands of the

Use of Casual Loop Diagrams and Systems Analysis to Explore Alternative Climate Change Adaptation Strategies in Seyhan River Basin, Turkey

Within a UN Joint Programme titled “Enhancing the Capacity of Turkey to Adapt to Climate Change” a systems approach workshop was carried out in Adana, Turkey with broad stakeholder participation. The participants applied systems thinking approach, causal loop diagramming methodology and systems analysis to examine the potential impacts of projected climatic changes on natural ecosystems and socio-

Neuroendocrine regulatory mechanisms in the choroid plexus-cerebrospinal fluid system

The CSF is often regarded as merely a mechanical support for the brain, as well as an unspecific sink for waste products from the CNS. New methodology in receptor autoradiography, immunohistochemistry and molecular biology has revealed the presence of many different neuroendocrine substances or their corresponding receptors in the main CSF-forming structure, the choroid plexus. Both older research
