Euro50 is a proposed optical telescope with an equivalent primary mirrordiameter of 50 m. Partners of the collaboration are institutes inSweden, Spain, Ireland, Finland, and the UK. The telescope will have asegmented primary mirror and an aplanatic Gregorian configuration withtwo elliptical mirrors. For a 50 m telescope there would be noeconomical advantage in going to a spherical primary. The siz
Linking scheduling attributes to control performance specifications is a difficult problem. This paper discusses how the MATLAB toolbox Jitterbug can be used to derive timing requirements for control loops from various control performance specifications. The resulting timing requirements include specifications on sampling periods, latencies, and jitter. An overview of the Jitterbug approach is giv
In reply to Welzel and Inglehart in this issue, we deploy three lines of criticism. First, we argue that their newly invented construct "effective democracy" is conceptually and empirically flawed. Second, we show that their results are highly sensitive to model specification. Regardless of the time period, their supportive evidence vanishes if a more pertinent measure of democracy is used instead
Systematic knowledge of entrepreneurship has evolved since the 1980s. In this study we will pay particular attention to the „knowledge producers‟ who have shaped the field over time but also to the „knowledge users‟ who have employed the core works in entrepreneurship in order to develop our knowledge of the phenomenon of entrepreneurship. A unique database consisting of all references in twelve „
A 5GHz digital frequency synthesizer achieving a low noise for wireless RF application is presented. This architecture uses a multi-delay coarse-fine Time-to-Digital Converter (TDC) to achieve both the large detection range and fine resolution. A Digitally Controlled Oscillator (DCO) based on capacitive degeneration in LC-Tank is also implement-ed. The DCO achieves frequency quantization step of 3
