Flexibility of connection impact the power of heterogeneous FPGA(连接复杂度对非对称FPGA功耗的影响)
Zhejiang Daxue xuebao. Lixue ban, 2010 FPGA因为开发周期短、使用灵活、价格低廉等优点,在嵌入式系统中被广泛应用.随着开发需求的扩大,嵌入有DSP、MCU等宏模块的非对称FPGA应运而生.本文根据非对称FPGA的结构,研究连接复杂度Fc参数对功耗的影响.在不同Fc参数的非对称FPGA结构下对MCNC电路仿真,实验结果表明输入Fc参数在80%,输出Fc参数在70%时,其功耗最低.与Fc参数100%相比,输入Fc参数在80%时,平均功耗减少25.76%,最高功耗减少29.08%;输出Fc参数在70%时,平均功耗减少27.07%,最高功耗减少43.

Zhejiang Daxue xuebao. Lixue ban, 2018 利用WRF模式，采用YSU、QNSE边界层参数化方案以及调整参数后的QNSE边界层参数化方案(MQNSE),对2009年7月梅雨个例、2015年苏迪罗台风以及2013年10月的近海大风进行了模拟试验，并对模拟结果进行对比检验，着重检验参数调整后的QNSE方案模拟沿海大风效果.研究结果如下：参数调整后的QNSE 边界层参数化方法改进了对沿海风场的模拟效果，尤其是当风速小幅脉动时，参数调整后的QNSE方案较接近于实况风速的波动.通过登陆台风个例模拟试验和对沿海10个岛屿观测站的490个样本统计检验表明 ...

Learner‐Focused Strategy Instruction From the Teachers’ and the Learners’ Perspective
International Journal of Applied Linguistics, EarlyView.ABSTRACT Numerous large‐scale quantitative studies have been conducted to yield a macro‐level picture of the effectiveness of strategy instruction. However, little is understood about learners' actual processing of strategy instruction and interaction with the teachers delivering it.

Gaoya dianqi, 2018 暂态恢复电压（TRV）标准值参数是考核高压交流断路器在大容量试验站进行短路开断试验时的一项重要指标。文中提出了一种基于坐标系转换的TRV波形包络线与标准值参数计算方法,通过对TRV波形数据经过数学运算由笛卡尔坐标系转换到极坐标系下,进一步对极坐标系下的TRV波形数据计算可以得出与TRV波形相切的3条直线（两参数TRV）或4条包直线（四参数TRV）所组成的包络线以及TRV的标准值参数。应用该计算方法所获得TRV标准值参数,为大容量试验站进行短路开断试验时,预期TRV调试时试验回路R、L ...
