The overhead crane is also a typical underdrive method, which has fewer inputs than the amount being controlled. In some practical applications, uneven weight and f-loads on the hook can lead to load and hook oscillations and the bridge crane can develop the so-called double-pendulum properties. This leads to a high degree of coupling and a high degree of non-linearity between the various state variables of the crane system. The study that follows suggests a new energy-coupled control strategy for an underactuated double-pendulum overhead crane with initial control force constraints. Strong robustness and superior control performance to parameter changes and external disturbances are the proposed controller’s noticeable characteristics. To ensure the smooth start of the trolley, a robust control adds the hyperbolic tangent function to the control procedure. In addition, the stability analysis and stability verification of the control system is given by using the LaSalle’s invariance principle and Lyapunov techniques. The simulation results show that the new energy coupling control method has stability and strong robustness under various conditions such as different rope lengths, load quality, target position and external disturbance when the initial control force decreases.","PeriodicalId":20688,"journal":{"name":"Proceedings of The 6th International Conference on Innovation in Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76952019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The use of an algal facade system that generates energy sources through building components can be suggested as one of the new efficient alternatives to solve this system. Methods: Microalgae are a type of living microorganism that is in the simplest form of a plant sample and mainly single-celled. Compared to other plant species, these organisms have a very high ability to absorb air pollution due to the high surface-to-volume ratio. By absorbing carbon dioxide from air or water during photosynthesis, they produce about 60 to 75 percent of the oxygen needed by humans and animals, which is 10 times more than a mature tree and photosynthetic grass. Findings: In this research, in the first stage, based on valid scientific articles and library studies, new information is collected and produced, and then the behaviour of microalgae bioreactors is investigated and the possibility of replacing old panels with bioreactors is investigated. Conclusion: The use of alternative energy due to the reduction of energy resources and no destruction of the environment, and the use of environmentally friendly energy using microalgae, in addition to producing the required oxygen, by adding bioreactor panels as an additional view the building has been designed to create privacy and proper view of the building facade.","PeriodicalId":20688,"journal":{"name":"Proceedings of The 6th International Conference on Innovation in Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85850258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Sunflower has become an important crop for both farmers and consumers in Sudan, fits well in the local cropping system and is considered the most important cash crop of the country. The experiment was conducted in the Experimental Farm, University of Kassala (New Halfa) of Sudan, to investigate the influence of cultivars and planting Spacing on plant growth and yield of Sunflower (Helianthus annuus L). It consisted of two cultivars (pannar-735 and Damazin-1) and three plant spacing’s (10 cm, 20 cm and 30 cm). Treatments were arranged in a factorial randomized complete block design (RCBD), in three replications. The results revealed, the cultivar, pannar- 735, early flowering, significantly highest hundred seed weight, seeds number per disc, seed yield (g/plant) and final yield (3.00 ton/ha). The Intra-row spacing of 30 cm had a thicker stem diameter, a highest number of seeds per head, 100-seed weight, seed yield per plant and final seed yield (3.34 ton/ha). The study revealed that the sunflower hybrid pannar-735 and plant spacing 30 cm apart is the best for New Halfa Eastern of Sudan.","PeriodicalId":20688,"journal":{"name":"Proceedings of The 6th International Conference on Innovation in Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82897186","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
