Infection of human intestine by parasites can be due the food that we eat or the water that we drink.

Intestinal parasites of protozoa and helminthes may cause disease or even death to animals and humans. In a current study of fecal sample examination to detect parasites, a technologist examines images manually using a lighted microscope. This method of examination is known to be inefficient when it involves a large number of samples. On top of that, it is very important to introduce a system that...
The paper compares three PWM control methods on a single-phase Z-source inverter (ZSI); traditional, simple-boost (SB-PWM), and modified-reference (MR-PWM). A model of the inverter in an open-loop system was built in Matlab/Simulink. The methods and their modulation indices were analyzed against two design parameters (dc-input voltage and switching frequency), the analysis basing determination of...
