It contains vital elements for maintaining people's health. Traditional technologies and principles of growing crops will not lead to the desired increase to this agricultural production.The new technologies will be created or some of these traditional technologies will be changed to respond to market needs. The first step is to use principally new or innovative mechanized technologies to increase yields. One such technology is that of weed control and destroy without human intervention. This will free up human resources for other operations. In this case, are rely on an autonomous system for long-term cultivation and weed control.This article discusses the highlights of such a technology for weed control without human intervention. These highlights are the positioning of the robot in the plantation, the exact location of its position and data retrieval of meteorological and soil conditions, the transmission and reception of data via IoT as well as artificial intelligent control. Other important points are the preparation of the equipment, the destruction of weeds system and artificial intelligence control of mobile robot. The destruction itself is carried out with hot air, paying attention to the temperature of the hot air, the duration and direction of heating.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"165 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122142009","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}

For this reason, water now appears as a limiting factor and becomes extremely important from an environmental and economic point of view. Saving irrigation water can be achieved by using efficient methods such as drip irrigation. In order to clarify the problem of sustainable use of water for irrigation, it is necessary to analyze the hydraulic and energy-efficient characteristics of water movement in irrigation systems and the conditions under which its transport and distribution to agricultural crops takes place. In the case of polyethylene - PE irrigation laterals for drip irrigation, a water quantity is consumed along their length. Under this condition, the flow rate gradually decreases and this leads to the formation of different flow regimes along the pipeline. In the present study, the question of the length of the part of the PE pipeline with laminar regime is considered, as well as the conditions predetermining the onset of this regime in PE pipelines ф 16/2 and ф 20/2. The conditions depend on the number of water localized outfalls, i.e. drippers, the magnitude of their flow rate, and the distance between them for a given assumed inner diameter and water temperature.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131291032","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}

Tests have been carried out to determine the duration of the periods for increasing the braking deceleration to its maximum value (t3) and for the movement of the vehicle with maximum braking deceleration (t4). The values of the corresponding decelerations during these time intervals are determined. The results of the research show that the increased time during the first period determines a longer distance traveled and a correspondingly lower value of the average braking deceleration during the period immediately after the impact on the brake pedal. For vehicles without ABS, the initial speed at which the vehicle approaches the interval t4 is lower due to the longer duration of the period t3. To this increase in time and distance traveled is added the movement of the vehicle in the next period, in which a smaller value of the average maximum braking deceleration is also registered.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114738411","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}

After a model of the electric field of the metal screw-device casing electrode system was created in the Finite Element Method Magnetics (FEMM) software environment, optimization of the working chamber design was performed. It was found that in certain sections (problem zones) of the working chamber of the treatment device the electric field was non-uniform. This resulted in a poorer efficiency of the seed pre-sowing treatment.After an optimization was performed, a new design of the working chamber screw was proposed. The shape of the modified screw followed the curves of the equipotential lines of the electric field in the working chamber. In this way, a change in the electric field pattern in the problem areas of the interelectrode space was achieved. In the proposed new design of the working chamber of the device, the treated seeds will be subjected to an effective pre-sowing impact.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134552082","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}

Transport is one of the biggest polluters. Many cities are turning to bicycles as alternative means of transport and are creating and expanding their bicycle networks. Electric bicycles are becoming increasingly popular, but they are still new and their designs are often not well optimized. An analysis of various models of commonly used batteries, in terms of their suitability for use in different types of electric bicycles, has been done. The analysis is based on the results of a long-term study related to the maximum achievable run for a daily used electric bicycle in relation to electric motor powers and available battery chargers. The conclusion is that modern electric bicycles still have certain critical design deficiencies which could be improved. The aim of this work is their designs to be optimized and the operating costs to be reduced, which will make them safer, more competitive and will stimulate their widespread use. This optimization is expected to help for the achievement of the difficult climate goals.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134329214","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}
