A pulse-echo contact method was applied for precise measurement of thickness. Transducers with delay lines, emitting at 5 MHz, 10 MHz, 15 MHz and 20 MHz, were used to determine the operating frequency range. An analysis of a number of echoes, amplitude and shape of signals, pulse duration and pulse rise time was performed. Ceramic plates of six Peltier modules, models TEC1-12708 and TEC1-12710, were measured with a selected transducer of 15 MHz. Thicknesses at 25 points of each plate were determined. Variation of the obtained values is observed. Comparative analysis of the results for all measured plates can be used for quality evaluation of the modules.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"59 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":"128142739","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 normative requirements for the cleanliness of rooms through the measurement of some key parameters such as carbon dioxide, amount of oxygen, fine dust particles, radiation levels, light, noise, humidity, etc. are discussed. The measurement methods for most of these parameters are carried out using specialized equipment by regulatory bodies. The prescribed limiting levels are specified in certain standards depending on the type of facility- public spaces (stations, airports), work rooms, civil protection facilities, etc. The critical overview aims to specify the requirements for a monitoring system which will allow preventive control of the abovementioned parameters. Thus, it will facilitate favourable, healthy and safe working conditions for personnel and other interested parties.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"77 3 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":"131484328","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}

It was found that the compensation of reactive loads in the conditions of deteriorated electric energy (EE) quality does not ensure good results. In this regard, a significantly better and more efficient technical solution developed according to the criterion of \"high quality EE\" is proposed.

The main aspects considered during the design are modularity, ease of manufacturing, and, of course, good thermal properties. The chamber is built on a metallic frame with 50 mm mineral wool walls which is a good thermal insulator. A 2kW heater is used to heat the thermal chamber and a custom tuned control algorithm is used for temperature control, with multiple approaches being presented. The maximum temperature range foreseen for the thermal chamber is between ambient and 85° C which is obtained with the current setup.

During operation rectifier voltage changes both under the influence of external factors (temperature) and due to degradation of semiconductor crystal. The task of determining the technical state of the rectifier (the presence and the stage of faults development) based on monitoring of its parameters is actual. This article presents the methodology of modeling of diode open- and short-circuit of single-phase bridge rectifier. The open circuit simulation is achieved by including a resistor in series with the diode. It was found that output voltage of rectifier at no-load is determined by reverse resistance of diodes. When the rectifier works under load its voltage is determined by the ratio of diode resistance to the total rectifier resistance. Short-circuit simulation is achieved by shunting the diode. A generalized model of single-phase rectifier operability is given. The use of this model will make it possible by comparing the rectifier input and output voltages to determine the nature and degree of diode fault development.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"2 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":"114781962","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}

In traditional farming sheep, goats, cows and other livestock are generally bred by inserting average amounts of food supplies into predefined containers. Main goal is maximizing milk and/or meat gains. In recent years a new concept has emerged in the realm of smart farming - Precision Livestock Farming – which aims not only increasing production and efficiency in the livestock sector, but also reducing costs and ensuring adequate feeding amounts for each separate animal. This paper describes a system using two newly emerging technologies, namely IoT and machine learning. The proposed system records the biological clocks of animals according to their daily eating patterns and then based on the recorded data estimates the feeding amount and feeding times and ensures they are according supplied with food.","PeriodicalId":441906,"journal":{"name":"2022 8th International Conference on Energy Efficiency and Agricultural Engineering (EE&AE)","volume":"2672 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":"128367725","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}
