  • 분화 양액 재배에 있어서 저면 관수 방식은 두상 관수 방식 보다 더 널리 사용되고 있다. 저면 관수 방식의 장점으로는 지상부에 물이 닿지 않아 고품질의 식물체 생산 가능, 균일한 크기의 식물체 생산 가능, 물과 양분의 사용의 줄임 등이 있다 (Newman, 1999). 현재 유럽은 저면 관수방식의 대표적인 ebb-and-flow 시스템이 상용화 되어있으며, 북미에서도 점점 그 사용 비율이 증가하고 있다 (Biernbaum, 1990). (중략)

  • Motivated by the convolution product of white noise functionals, we introduce a new notion of convolution products of white noise operators. Then we study several interesting relations between the convolution products and the quantum generalized Fourier-Mehler transforms, and study a quantum-classical correspondence.

  • Fractional Brwonian motion(fBm) has properties of behaving tails and exhibiting long memory while remaining Gaussian. In particular, it is well known that interest rates show some long memories and non-Markovian. We present no aribitrage condition for HJM model under the multi-factor fBm reflecting the long range dependence in the interest rate model.
