An analytic approach for the estimation of the phase and amplitude imbalances caused by component mismatches and parasitic magnetic fields in two popular quadrature LC oscillators is presented. Very simple and closed-form equations are derived, proving that, although the two topologies share the same small signal circuit, they display very different sensitivities to the mentioned sources of imbala

The fourth International Society of Blood Transfusion (ISBT) workshop on molecular blood group genotyping was held in 2010, with a feedback meeting at the ISBT Congress in Berlin, Germany. Fifty laboratories participated, 17 more than in 2008. Six samples were distributed. Samples 1-3 were DNA samples for all red cell blood group tests available to the participants. Of the 46 laboratories that tes

BACKGROUND: During the therapeutic videofluoroscopic examination of swallowing, gradation of bolus volume, texture, and viscosity can be implemented to determine the optimal bolus characteristics in that particular patient. When a thickened liquid is given to a dysphagic patient it is served at room temperature. However, in these patients with a delayed oral and/or pharyngeal stage of swallow, the

A new EU directive on used vehicles has recently been introduced. It demands that for every scrapped car, at least 85% by weight must be recycled by the year 2006 and 95% by 2015. Today this level is about 80%. The growing car disassembly industry was chosen as the study object of this thesis. Due to the increased demands on recycling, the disassembly industry is expected to undergo comprehensive

The use of test-coverage measures (e.g., block-coverage to control the software test process has become an increasingly common practice. This is justified by the assumption that higher test-coverage helps achieve higher defect-coverage and therefore improves software quality. In practice, data often show that defect-coverage and test-coverage grow over time, as additional testing is performed. How

Multitype branching processes have been employed to determine the stack algorithm computational distribution for one subtree. These results are extended here to the distribution of the number of computations in any finite number of subtrees. Starting from the computational distribution forK-1subsequent subtrees, a recurrent equation for the distribution forKsubsequent subtrees is determined.

In this article I argue that weak pronouns in the Scandinvian languages should be analysed as functional heads expressing pure phi-features, and that these heads occur either without complements or copying phi-features expressed in the rest of the extended projection. The description is modelled on a construction in Old and Modern Icelandic, where a pronoun may identify the phi-features of a delet

The article is about the symbolic meanings of animal ornamentation in a long term perspective. Special interest is payed to the relation between the images in animal ornamentation and verbal expressions in early medieval skaldic poetry. The article also deals with animal ornamentation in a gender perspective.

This paper suggests a number of facts related to the modeling and output feedback stabilization of the Moore-Greitzer compressor model. It shows how to integrate the stall dynamics, and how to use this for further output stabilization of the model.

Background: Ischemic postconditioning (PostC), brief repetitive cycles of ischemia and reperfusion during early reperfusion, is suggested to protect the myocardium in patients with stent thrombosis-elevation myocardial infarction (STEMI) by improved endothelial dysfunction and alteration of cytokine release. These mechanisms are also of importance for the recruitment of endothelial progenitor cell
