  • 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....

  • Bat and dolphin use sound to survive and have greatly superior capabilities to current technology with regard to resolution, object identification and material characterisation. Some bats can resolve some acoustic pulses thousands of times more efficiently than current technology (Thomas & Moss, 2004 ). Dolphins are capable of discriminating different materials based on acoustic energy, again significantly out-performing current detection systems.

  • 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.

  • 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 goal of our research is to develop an autonomous robot for subsurface mapping. We are motivated by the growing need for mapping buried pipes, hazardous waste, landmines and other buried objects. Most of these are large scale mapping problems, and to manually construct subsurface maps in these cases would require a significant amount of resources. Therefore, automating the subsurface mapping process is an important factor in alleviating these problems. To achieve our goal, we have developed a robotic system that can autonomously gather and process Ground Penetrating Radar (GPR) data.

  • 'In fact it's about three million years old.You are looking at the first proof of intelligent life beyond the Earth.' The speaker is Dr Roy Michaels, Chief Scientist at the Clavius Base on the Moon. The audience has been carefully chosen, because it is too soon to tell the world's population that they are not alone in the universe. On the screen behind Dr Michaels is a photograph of a black object about three metres high, of regular shape and with straight edges. It was certainly made by an intelligent form of life, and it was found buried under the surface of the Moon....

  • When a NASA satellite discovers an astonishingly rare object buried deep in the Arctic ice, the floundering space agency proclaims a much-needed victory -- a victory with profound implications for NASA policy and the impending presidential election. To verify the authenticity of the find, the White House calls upon the skills of intelligence analyst Rachel Sexton.
