简介：作为Dante^TM可扩展DSP产品线的最新成员,Prism数字信号处理平台为各种固定安装应用提供高性价比的网络音频处理。SymetrixPrism包括4个型号,仅在输入/输出通道数量和尺寸方面有所区别。Prism4×4具有4路输入和4路输出,通过以太网供电（PoE＋）.

简介：棱柱的重力的潜力的决心在物理测地学和地球物理起一个重要作用。然而，有很少文学，为决定棱柱的重力的潜力提供精确途径。分离元素方法能被用来决定棱柱的重力的潜力，并且能接近有足够的精确性的真重力的潜在的价值(每个元素越小，结果越精确)。尽管Nagys途径提供了关上的表情，一个人不知道它是否是有效的，由于这条途径没在文学被证实的事实。在这份报纸，有分离元素方法的Nagys途径的比较上的研究被介绍。结果证明为决定棱柱的重力的潜力的Nagys公式在内并且在棱柱外面在领域是有效的。
