Abstract: The solar chimney is an innovation, which has been as of now demonstrated of being able to create electrical vitality from the sun likewise it has been introduced in different structures for ventilation, and next to no is thought about their genuine presentation and very panics are the application. This research work deals with the development of a physical, mathematical and computational models of roof solar chimney to rationalize the performance of ventilate in residential house. A thermal model enables to easily determine the inclination angle, absorber area, cavity width of the chimney and the air flow rate, using MATLAB. The simulation has been done for selected residential house of 264m3 located at Bahir Dar city, Ethiopia @ 11° latitude and 37° longitude. At comfort air speed (2m/s), a south faced system being tilted at an angle of 45° will have absorber length, the absorber height and cavity width about 3m, 4.24m, and 0.5m respectively. This will enable the residential house to circulate the air 560kg per hour. The maximum air temperature obtained at chimney outlet is 44.5°C. For a month of April an average solar intensity value is 900 W/m2. The main factor to induce buoyancy is solar insolation since it directly influences the air temperature, and the efficiency is about 44.4%.

Abstract: The level of education, training of researchers and technologists and international scientific, technological and technological development allows the world community to gradually move to the formation and management of the industry 5.0 through the cognitive technological mind with the help of ensembles of intelligent agents and digital twins and automated systems with artificial intelligence. The cognitive technological mind on the speech mission of a person forms a design implementation for ensembles of intellectual agents. The ensembles of intelligent agents for the project implementation of a human task activate the work of digital twins with artificial intelligence, corresponding to the industry, for the production implementation of a human task. Cognitive technological intelligence, intelligent agent ensembles, and digital doubles make decisions based on representative data. Their representativeness is reflected by the similarity of the data in terms of the qualitative properties and characteristics of a certain production. Through cognitive technological mind with the help of ensembles of intellectual agents it is also possible to manage financial, ecological and other activities of enterprises of industry 5.0. Cognitive technological mind, ensembles of intellectual agents and digital doubles are a very effective tool of automation of management in all spheres of life of society and the state. The international scientific engineering community can begin the formation and technical implementation of industry control automation systems 5.0 based on cognitive virtual mind with artificial intelligence, additive technologies and 5G network. Sensitive safe robots with cognitive artificial mind will perform high-tech professional work in various fields of industry 5.0. A person will teach robots with a cognitive mind to increase professionalism by recursive self-improvement to technological singularity. Artificial intelligence with technological singularity will be controlled by the results of self-improvement in simulation mode in virtual space. He can become a good assistant to humanity in the safe development of living spaces.
