| 1 | Coupled simulation of BES-CFD and performance assessment of energy recovery ventilation system for office model显示文摘Thermal comfort and indoor air quality as well as the energy efficiency have been recognized as essential parts of sustainable building assessment.This work aims to analyze the energy conservation of the heat recovery ventilator and to investigate the effect of the air supply arrangement.Three types of mixing ventilation are chosen for the analysis of coupling ANSYS/FLUENT(a computational fluid dynamics(CFD) program) with TRNSYS(a building energy simulation(BES) software).The adoption of mutual complementary boundary conditions for CFD and BES provides more accurate and complete information of indoor air distribution and thermal performance in buildings.A typical office-space situated in a middle storey is chosen for the analysis.The office-space is equipped with air-conditioners on the ceiling.A heat recovery ventilation system directly supplies fresh air to the office space.Its thermal performance and indoor air distribution predicted by the coupled method are compared under three types of ventilation system.When the supply and return openings for ventilation are arranged on the ceiling,there is no critical difference between the predictions of the coupled method and BES on the energy consumption of HVAC because PID control is adopted for the supply air temperature of the occupied zone.On the other hand,approximately 21% discrepancy for the heat recovery estimation in the maximum between the simulated results of coupled method and BES-only can be obviously found in the floor air supply ventilation case.The discrepancy emphasizes the necessity of coupling CFD with BES when vertical air temperature gradient exists.Our future target is to estimate the optimum design of heat recovery ventilation system to control CO2 concentration by adjusting flow rate of fresh air. | Yunqing FAN T.Hayashi K.Ito | 2012 | Journal of Central South University2012，19，3： | 4 |

| 10 | 地震现象的新观点显示文摘本文综述断裂和碎形理论的最新进展。以分形的观点解释地震学经验公式,提出了地震作为自组织临界现象(SOC)的观点。地震的发生是地壳中的能量耗散过程,而地壳构造能量连续地得到补给。地壳的自组织行为达到临界状态,时间上和空间上的分形结构就自然地呈现出来。众所周知,在地震学中幂次律关系即是地壳临界状态的表述。本文还提出了一个地震的SOC模型,用以解释古登堡-里克特公式、大森的余震公式以及震源的分形分布。地震现象的新观点与其它用一个完整的理论来研究复杂的现象的学科一样,有着共同的立足点。 | K.Ito 郑文衡 王静瑶 | 1995 | 世界地震译丛1995，26，3： | 1 |

| 12 | Determination of Interrogating Frequencies to Maximize Electromagnetic Backscatter from Objects with Material Coatings显示文摘The electromagnetic backscattering of a crosscut of a cruise missile coated by a thin homogeneous layer made of radar absorbent material is modeled using a finite element method.Based on the radar cross section and a reflection coefficient,optimization problems are formulated for evaders and interrogators leading to optimal material parameters for the coating and optimal monostatic radar operating frequencies,respectively.Optimal coating materials are constructed for several radar frequencies.Tuning only dielectric permittivity gives a narrow frequency range of high absorption while also tuning magnetic permeability widens it significantly.However the coating layers considered do not provide substantial reduction of backscattering in the entire frequency range from 0.2 to 1.6 GHz.Computational experiments also demonstrate that the reflection coefficient based on a simple planar geometry can predict well the strength of radar cross section in the sector of interest with a substantially reduced computational burden. | H.T.Banks K.Ito J.Toivanen | 2006 | Communications in Computational Physics2006，1，2： | 0 |
| 13 | Dynamic Evasion-Interrogation Games with Uncertainty in the Context of Electromagetics显示文摘We consider two player electromagnetic evasion-pursuit games where each player must incorporate significant uncertainty into their design strategies to disguise their intension and confuse their opponent.In this paper,the evader is allowed to make dynamic changes to his strategies in response to the dynamic input with uncertainty from the interrogator.The problem is formulated in two different ways;one is based on the evolution of the probability density function of the intensity of reflected signal and leads to a controlled forward Kolmogorov or Fokker-Planck equation.The other formulation is based on the evolution of expected value of the intensity of reflected signal and leads to controlled backward Kolmogorov equations.In addition,a number of numerical results are presented to illustrate the usefulness of the proposed approach in exploring problems of control in a general dynamic game setting. | H.T.Banks Shuhua Hu K.Ito Sarah Grove Muccio | 2011 | Numerical Mathematics(Theory,Methods and Applications)2011，4，3： | 0 |
| 14 | Catalysis on Interface of Nano-oxide and Nano-zeolite显示文摘1 Results The catalysts which can efficiently hydro-reform higher n-paraffin to lower isoparaffins for environmentally-friendly gasoline were studied. The catalysts were examined by the conversion of n-hexadecane, n-C16H34 to i-C6H14—i-C10H22.The tri-modally nano-porous catalysts composed of (Ni-Mo)/[γ-Al2O3], nano-oxide, and nano-crystalline zeolite had some active and selective performance because of the interface between nano-oxide and nano-zeolite. The catalyst composed of nano-crystalline MFI or BE... | K.Ito F.Jan S.Asaoka | 2007 | 复旦学报(自然科学版)2007，46，5： | 0 |
