Zig-Zag valley detection

Zig-Zag valley detection is a technique used in technical analysis to identify areas of support and resistance in a financial market. It involves drawing trend lines connecting the peaks and valleys of price movements.

A zig-zag valley is a pattern of price movement where the price makes a series of higher highs and higher lows, followed by a series of lower highs and lower lows. This creates a zig-zag pattern on a chart.

Traders use zig-zag valley detection to identify potential areas of support and resistance, where the price may reverse direction. This can help them make trading decisions such as entering or exiting a position.

zig-zag 扫描公式

Zig-zag 扫描公式是一种在数字或矩阵中按照特定顺序进行扫描的方法。它的特点是在扫描时以“之”字形的方式进行，先水平后垂直或先垂直后水平地进行扫描。

以矩阵为例，假设有一个4x4的矩阵：
1 2 3 4
5 6 7 8
9 10 11 12
13 14 15 16

按照zig-zag 扫描公式进行扫描的顺序为：
1 2 5 9 6 3 4 7 10 13 14 11 8 12 15 16

在实际应用中，zig-zag 扫描公式常用于图像和视频压缩编码中，可以较为高效地表示和传输矩阵中的数据。它的扫描顺序具有一定的规律性和紧凑性，有利于减小数据传输的体积和加快数据的处理速度。

在编程实现中，可以利用循环嵌套的方式按照zig-zag 扫描公式的顺序来访问矩阵中的元素，从而实现数据的读取和处理。因此，zig-zag 扫描公式在实际应用中有着广泛的用途，并且在数字信号处理领域中有着重要的地位。

用中文总结以下内容： A number of experimental and numerical investigations have been conducted to study the MBPP stack and wavy flow field characteristics with various designs [10,11]. T. Chu et al. conducted the durability test of a 10-kW MBPP fuel cell stack containing 30 cells under dynamic driving cycles and analyzed the performance degradation mechanism [12]. X. Li et al. studied the deformation behavior of the wavy flow channels with thin metallic sheet of 316 stainless steel from both experimental and simulation aspects [13]. J. Owejan et al. designed a PEMFC stack with anode straight flow channels and cathode wavy flow channels and studied the in situ water distributions with neutron radiograph [14]. T. Tsukamoto et al. simulated a full-scale MBPP fuel cell stack of 300 cm2 active area at high current densities and used the 3D model to analyze the in-plane and through-plane parameter distributions [15]. G. Zhang et al. developed a two-fluid 3D model of PEMFC to study the multi-phase and convection effects of wave-like flow channels which are symmetric between anode and cathode sides [16]. S. Saco et al. studied the scaled up PEMFC numerically and compared straight parallel, serpentine zig-zag and straight zig-zag flow channels cell with zig-zag flow field with a transient 3D numerical model to analyze the subfreezing temperature cold start operations [18]. P. Dong et al. introduced discontinuous S-shaped and crescent ribs into flow channels based on the concept of wavy flow field for optimized design and improved energy performance [19]. I. Anyanwu et al. investigated the two-phase flow in sinusoidal channel of different geometric configurations for PEMFC and analyzed the effects of key dimensions on the droplet removal in the flow channel [20]. Y. Peng et al. simulated 5-cell stacks with commercialized flow field designs, including Ballard-like straight flow field, Honda-like wavy flow field and Toyota-like 3D mesh flow field, to investigate their thermal management performance [21]. To note, the terms such as sinusoidal, zig-zag, wave-like and Sshaped flow channels in the aforementioned literatures are similar to the so called wavy flow channels in this paper with identical channel height for the entire flow field. The through-plane constructed wavy flow channels with periodically varied channel heights are beyond the scope of this paper [22,23].
