摘要：This paper examines the architectural and Landscape design strategies and intentions for green, open spaces facilities targeting stress aLLeviation for learning environments such as those of university campuses in a compact urban setting. Literature reviews provide three prevailing perspectives for physical design pedagogical operatives： healing gardens where greenery and plants produce restorative effects; flexible spaces that accommodate functional needs of different activities; and green buildings that incorporate open space as a catalyst for integrated eco-system. Corresponding design approaches （Landscape design, spatial design and green design） are scrutinized by case study. A comparison of two university campuses with different urban contexts is conducted to identify challenges and opportunities for applying these design approaches. For a compact campus, high-dense surroundings may limit the size of an open space and may handicap circulation and accessibility; on the other side, a small open space may provide its users more intimate contact with natural restorative elements and also a more controllable microclimate for physical comfort. A healthy campus should encompass diverse open spaces to satisfy different purposes. Finally, a framework that integrates the three approaches is combined to produce a sustainable design rubric.

摘要：基于FPGA/ASIC的全数字硬件化方案具有全定制性和并行性的优点,为了利用最小的硬件资源实现指定的系统性能,需要对系统性能指标和实现代价进行优化设计。全数字锁相环性能指标函数是优化设计的前提,然而其却无法在s域内被完备、准确地描述。本文在z域内建立包括峰值时间、调节时间及超调量的全数字硬件化锁相环性能指标函数,指出由于反馈滞后一拍特性使系统的性能产生退化,然后定量地描述全数字硬件化锁相环的性能指标退化规律。仿真和实验结果表明峰值时间的退化现象较弱,而调节时间和超调量的退化规律类似,等值线退化为开口向下的抛物线,使比例、积分系数的耦合加强。

摘要：基于FPGA/ASIC的全数字硬件化方案具有纯硬件性、高度并行性及全定制性等优点,是一种高速高性能的基于锁相环的磁编码器轴角转换单元设计方案。然而它却面临内部参数域确定及字长选取等问题,而上述问题与离散周期存在着紧密的联系。本文首先利用Delta算子对连续域的锁相环进行离散化,依据Delta域稳定性条件分析离散周期对锁相环的稳定性的影响机理,从而确定系数整数字长。然后通过建立误差源及误差传播路径L2范数模型,研究离散周期对改进结构锁相环的变量小数字长的影响规律,从而得到系统内部变量的小数字长设计的理论依据,最后的实验结果验证了分析的正确性。
