천체의 모양을 비교해 해당 천체의 실체를 파악했다.최근 연구자들은 ‘문서 마이닝(mining)’ 분야를 집중 연구하고 있다. 검색 단어나 문장을 집어넣으면 컴퓨터가 산더미 같은 문서파일을 뒤져 본문을 읽고 내용을 분석한 후 요약 정보와 함께 관련 결과를 내놓는다. 예를 들어 유전학자가 새로 ...
같은 새로운 학습 방법이 개발돼 왔다. 최근 많은 관심을 모으고 있는 데이터마이닝(Data Mining)도 학습 기법을 이용한 것이다. 데이터를 분석하고 그 속에 감추어진 패턴이나 규칙을 추출함으로써 이를 고객관리, 판매전략 수립, 의료진단 등에 널리 응용하고 있다.학습기능을 이용하면 많은 분야를 ...
brevis reduce seed foramation by eating the flowers of the purple loosestrife. Hylobius transversovittatus is a root mining weevil. Galerucella calmariensis and Galerucella pusilla are leaf-eating beetles.Scientists say that in the history of biological control methods, introduced insects have never become serious pests of any native species or crop plants. According to experiments now under ...
as 2 million years ago.If we were to go back to the moon, then, quite apart from its uses as an observatory, a mining station, an a new home for human beings, a careful and painstaking study of its surface could fill in all the details of its history and from that we could deduce what took place on the early Earth, too. The clues we find there might help us figure out how life began on this ...
produced in the laboratory.Two American scientist Edward Franzblau and Carl popp, from the New Mexico Institute of Mining and Technology, have now turned to nature itself. Recently, they worked out a method for calculating the amount of nitrogen dioxide formed in actual lightning flashes during thunderstorms.After studying about 60 flashes, they calculated that each flash produces about a ...
