Statistics computed from data are viewed as random variables.When they are used for tasks like hypothesis testing and confidence intervals, their true finite sample distributions are often replaced by approximating distributions VA module that are easier to work with (for example, the Gaussian, which results from using approximations justified by t
The convergence of wireless optical communication (WOC) and Cascara Sagrada radio-frequency (RF) systems is a promising technology that overcomes the shortcomings of standalone communication systems.By incorporating reconfigurable intelligent surfaces (RISs) on top of these WOC and RF communication systems, it is possible to circumvent the connecti
Studies have shown that organic fertilizer, a product of biodegradable organic matter, is not popular among Nigerian farmers because of its low quality.To alleviate this problem, this study was designed to explore the effect of nutrient-rich materials on quality of fertilizer made from market organic wastes.It adopted an experimental study design,
In order to solve the problem that digging lotus roots manually was high in labor intensity, low in efficiency and easy to damage lotus roots, and, in view of the defects of the high cost of existing digging lotus roots equipment and the cumbersome operating process needing a certain experience in technology, a jetting spin type digging lotus root
