Tuyển tập báo cáo các nghiên cứu khoa học quốc tế ngành hóa học dành cho các bạn yêu hóa học tham khảo đề tài: Simultaneous buried object detection and imaging technique utilizing fuzzy weighted background calculation and target energy moments on ground penetrating radar data
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
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.
