采样

In this algorithm, the direction-of-arrival is assumed to be a discrete random variable with a priori probability density function defined on a set of candidate points. Whether or not the secondary sample is required is based on the a posteriori probability distribution of a set of candidate point"s, which can be calculated from the array received signals. And then, the resulting beamformer is a weighted sum of the beamformers pointed at the latest set of point"s, which are combined according to the value of the a posteriori probability for each pointing direction.

在该算法中，期望信号的波达方向被看作是一个定义在若干候选波达方向上的离散随机变量，由阵列接收信号计算出各候选波达方向的后验概率，并将后验概率的分布作为是否需要进行二次采样的判断标准；随后，对各波达方向上的波束成形权值线性加权，便可得到自适应波束成形器，权系数为各候选波达方向的后验概率值。

A decoupling generalized predictive control algorithm was presented in this paper. This algorithm was proposed to control the temperature-humidity system of a practical air-conditioning environmental chamber. By introducing absolute humidity as an intermediate variable,temperature and humidity of the system can be decoupled.

为保证多变量控制系统长期安全而有效运行，提出一种解耦GPC控制算法，该算法通过引入绝对湿度作为中间变量，将温、湿度耦合系统进行解耦，然后对解耦后的两个系统进行不同采样周期的GPC控制律设计，给出了该算法的仿真研究结果。

The equivalent-time sampling speed of a scope is not a measure of the speed of its ADC, but an estimate of the speed of an imaginary ADC that could capture a single-shot waveform at the same timebase, and with the same number of samples, as the sampling scope in question.

示波器的等效时间采样速度并不是量测ADC的速度，但是可以假想为在相同时基，相同样点数能够捕获单次波形的虚构的ADC，做为讨论中的采样示波器。

Exibility for point sampling. Secondly, by combining the splat-ting algorithm with Layered Depth Buffers, we implement an algorithm fordetermining the points'visibilities and re?ectance properties, which is more accuratethan pervious methods.

其改进之处包括两点：一方面，根据灭点的性质，设计出等间隔索引表的结构来组织采样图像中物体的轮廓边，有效地提高了点采样的效率；另一方面，通过将splatting绘制算法和层次深度缓存的数据结构相结合，提出了一种高精度的点云可见性判断算法，从而克服了已有方法存在可见性判断误差的缺点。

Ground parts: an overhead-type indicator by sampling ground capacitance transient current in the first half-wave and ground transient voltage in the first half-wave, to compare their phase, when the sampling ground capacitance transient current mutation and more than a certain value, and the instantaneous voltage and grounding The first-phase half-wave, while wire-to-ground voltage is reduced, then the judge circuit grounding occurred.

接地部分：架空型指示器通过采样接地瞬间的电容电流首半波与接地瞬间的电压首半波，比较其相位，当采样接地瞬间的电容电流突变且大于一定数值，并且与接地瞬间的电压首半波同相，同时导线对地电压降低，则判断线路发生接地。

In these cases, a low sampling rate like 10 Hz should do.

在这些情况下，采样率应该为10HZ左右的低采样率。
