Phased array antenna (PAA) calibration is the process of determining the PAA channel characteristics; these characteristics are used in beam forming algorithms. In "contactless" PAA calibration methods, measurements are made by a stationary probe antenna placed away from the tested antenna, and the channel characteristics are determined from the measured data. Two of these methods are the MTE and

The metaphors in the works of Birger Sjöberg is compared to those of Esaias Tegnér. The comparison is made in the theoretical frame of Riffaterre´s concept of hypogram (clichés, descriptive system) and the tradition of domesticating metaphors. Sjöberg is clearly developing Tegnér's metaphorical technique, thus shaping new ways of expressing the depths of mans psyche and his fate, understood within

Present digital logic gates are primarily built from field effect transistors (FETs) such as complementary metal oxide semiconductors with the gate length in the deep sub-μm regime. As device feature sizes approach the nanometer regime, fundamental physical constraints and increasingly prohibitive economic costs will make further miniaturization in electronic circuits difficult, and this has motiv

The society depends on reliable and robust services provided by technical infrastructures for its function. The impact of large-scale outages due to the inherent vulnerabilities of technical infrastructures has been demonstrated, for example, by the power outage in the U.S. in 2003 and the power outages in Sweden due to the storms Gudrun in January 2005 and Per in January 2007. Two of the main app

Abstract Purpose Treatment with blood pressure lowering drugs may reduce morbidity and mortality. However, the efficacy and effectiveness may differ between antihypertensive agents. The current investigation aimed to compare mortality and cancer incidence in hypertensive patients treated with calcium channel blockers (CCB) or with other antihypertensive drugs (AHD). Methods All patients in two o

Denna studie avser att undersöka den mening som mediciner skapar, och hur de påverkar människors vardagliga erfarenheter och identitetsskapande. Medicineringens relation till kroppsliga tecken och symptom påvisar den spänning som finns i synen på läkemedlet; mediciner som något farligt och riskfyllt men samtidigt med förmåga att förebygga och bota. Mediciners farlighet tycks delvis kunna motverkasThis study aims to explore the meaning that is created when using medicines, and how medicines affect older people’s experiences of everyday life and their identity. The connection between medicines and the body demonstrates the tension that the medications contain; something dangerous and unsafe but with the power to cure and prevent illness. The risks of medications seem to be counteracted throu

The intelligent peripheral (IP) is one of the key central resources in the intelligent network concept, allowing user to network interaction for services such as credit card calling. User access to IPs is controlled by service control points (SCPs) and is typically gained via voice trunk groups from service switching points (SSPs), with many services sharing common SSP-IP trunk group facilities. T

Constant volume combustion is studied, using a zero-dimensional model, which is a wide-ranging chemical kinetic simulation that allows a closed system of gases to be described on the basis of a set of initial conditions. The model provides an engine- or reactor-like environment in which the engine simulations allow for a variable system volume and heat transfer both to and from the system. The com
