The application of the designed electromagnet refers to systems for electromagnetic separation of medium and large steel parts that may be found in the coal that is transported on the conveyor belts for the delivery of coal to thermal power plants. The application of the electromagnetic separator is directly related to the system for detecting the presence of metal steel parts (metal detector). In the case of inefficient operation of the system for separation of steel parts from coal, severe accidents can occur in the system for grinding and crushing coal at thermal power plants. The design of the electromagnet presented in this paper was verified in the software package FEMM 4.2. The model is defined as a 2D planar magnetostatic model. At the end of the paper, the final simulation results of this project are presented.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"67 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76315142","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 certain periods during the day, the need to extend the interval of passage in certain directions at the intersection increases. In order to determine how to extend the interval, it is necessary to apply advanced technologies of the Internet of Intelligent Devices (IoT). Built-in sensors, in addition to the basic purpose of motion detection, also have the possibility of mutual communication as with other devices. The collection and immediate analysis of data in the database of the Traffic Dispatch Center (SDC) provides the service with information to improve the throughput of intersections in the direction that is most loaded. The main goal of the paper is to present an innovative model of traffic regulation of timely and immediate extension of the time interval for the necessary directions at the intersection.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"267 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79798393","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}

These materials are used on valve seats of internal combustion engines. Abrasion tests were performed on a T-11 pin-on-disc tester. The test conditions were similar to those prevailing during the operation of the valves in the head of the internal combustion engine, disregarding the influence of temperature. The TSI OPS 3330 optical spectrometer was used to measure the intensity of generation of wear particles, which enables the measurement of particles in the range from 0.3 to 10 $boldsymbol{mu mathrm{m}.}$ The obtained results indicate that the $boldsymbol{text{Fe}_{3}text{A1}}$ intermetal in contact with the 1.0037 S235JR steel generates 15% less airborne wear particles in the tested range.","PeriodicalId":6839,"journal":{"name":"2022 21st International Symposium INFOTEH-JAHORINA (INFOTEH)","volume":"4 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2022-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75191533","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}

We predict the emergence of novel in-terference effects with possible practical applications. For exam-ple, photons may exhibit a nontrivial dispersion relation such as band edges and band gaps. In this way, QMMs may be viewed as photonic crystals.
