One of the most important inventions for the development of radars was made by Christian Huelsmeyer in 1904. The German scientist demonstrated the possibility of detecting metallic objects at a distance of a few kilometres. While many basic principles of radar, namely using electromagnetic waves to measure the range, altitude, direction or speed of objects are remained up to now practically unchanged, the user requirements and technologies to realise modern radar systems are highly elaborated....

Diabetes represents a major threat to public health with alarmingly rising trends of incidence and severity in recent years, as it appears to correlate closely with emerging patterns of nutrition/diet and behavior/exercise worldwide. The concentration of blood glucose in healthy human subjects is about 90 mg/dl and defines the state of normoglycaemia. Significant and prolonged deviations from this level may give rise to numerous pathologies with serious and extensive clinical impact that is increasingly recognized by current medical practice....

The advent of novel materials for electronics, optoelectronics and nanoelectronics holds the promise for new microelectronic device designs and applications across all fields of science and technology. Furthermore, the increasing sophistication of fabrication processes and techniques used in the semiconductor industry has resulted in the ability to produce circuits of greater complexity at remarkably reduced costs, a trend which has been continuing over the past half-century.
