The Developed System of Continuous Utilization of Carbon Dioxide, Enrichment of the Atmosphere with Oxygen and Production of Biofuel Using the Resulting Concentrate of Rapidly Multiplying Microalgae
Abstract: It is known that microorganisms, such as microalgae, during photosynthesis utilize carbon dioxide and enrich the atmosphere with oxygen. Microalgae, on the other hand, can be converted into biofuels by extracting fatty acids from macromolecules known as lipids. Recovery of this fatty acid traditionally requires the removal of most of the water from the microalgae resulting in biomass slurry. The method developed earlier permitted to obtain a high-quality concentrate of …

Maximum Power Point Tracking of a Variable Speed Permanent Magnet Synchronous Generator Based Wind Energy Conversion System
Abstract: Wind turbines produce maximum power at the optimal tip-speed ratio. Fixed speed wind turbines are inefficient because the turbine blades rotate at a specific mechanical speed irrespective of the prevailing wind speed. The system is therefore, not able to extract the maximum possible amount of power. In this work, a maximum power point tracking scheme for a variable-speed permanent magnet synchronous generator based wind energy conversion system is implemented in …

Car License Plate Detection and Recognition using Morphological Image Processing and Template Matching
Abstract: This study presents a robust method for vehicle number plate detection and identification. It mostly consists of three stages: plate extraction, plate number separation, and number recognition. Morphological operation is used to extract plate and numbers, whereas template matching is used to recognize the extracted number images. After that, it looks into a predefined dataset to decide if the number is licensed. Being independent of plate size, color and illumination …
