INTRAOCULAR PRESSURE OUTCOME IN PRIMARY 5FU PHACOTRABECULEC- TOMIES COMPARED TO 5FU TRA- BECULECTOMIES

Introduction: Cataract & glaucoma commonly coexist and the surgical treatment of glaucoma may also be combined with pha-coemulsification. Combined surgery may not achieve as low intraocular pressure (IOP) as compared to trabeculectomy alone due to the increased inflammatory response associated

时间域网络解析器的精确度和速度在电力系统中的应用

通过比较5个商业软件包的精确度和执行时间,论文研究了具有固定时间和变换时间的网络仿真方法的性能差异。包含了多个三相二极管整理器和一个PWM电压源反向器的一系列基准实例显示:固定时间步长法对于线整流电路执行时间更具有优越性。然而,为了得到准确的结果,即使较低的开关频率PWM应用可能也需要非常小的时间步长。得到如下结论:当使用太大时间步长时,即使波形看起来是正确的, PWM反向器控制信号也可能有严重的错误。
