Special agar-based tissue mimicking material (TMM) were manufactured from agar with the addition of produced by us iron oxide magnetic nanoparticles of order c/a 11 nanometers. To perform comparison of heating by the measured temperature rise curves caused by the two physical fields differently acting on the material sample, in the case of ultrasonic radiation we did not locate the sensor of thermometer in the ultrasonic beam focus, as it was usually studied, but we put it in the place where distribution of ultrasound intensity was more homogeneous. It was motivated by the fact that the “homogeneous heating” by the magnetic iron oxide nanoparticles which are spatially homogeneously distributed should be compared with the ultrasonic heating effects caused by the spatially homogeneous ultrasonic sources. The obtained results confirm that for both fields, ultrasound and magnetic, the temperature increase was caused by the presence of nanoparticles. In the case of heating by magnetic field pure agar-gel was not heated at all, and during sonication the pure agar-gel exhibited very small thermal effect, due only to the structure of the agar-gel crosslinking. We concluded that the ultrasonic absorption was in our experiment greater than magnetic, but the temperature rise after 180 s of magnetic field action was greater than of sonication.","PeriodicalId":288282,"journal":{"name":"2019 Applications of Electromagnetics in Modern Engineering and Medicine (PTZE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125548120","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}

Red clover seeds were grown under controlled conditions, in Easy Green automatic seed drills without a substrate, on the bamboo fibers and on the textiles made of bamboo covered with a thin silver layer (KCB Ag). The energy and ability of seeds to germination was evaluated during the cultivation. It was shown that red clover seeds had similar germination energy regardless of the used cultivation conditions. It was also observed that the germination ability of the tested seeds grown on bamboo fiber coated with a thin silver layer was the highest and equaled to 98 ± 1%.","PeriodicalId":288282,"journal":{"name":"2019 Applications of Electromagnetics in Modern Engineering and Medicine (PTZE)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133548374","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}

This device allows for re-configuration of excitation waveforms. There are two main advantages of space-time waveform reconfiguration. First, the ability of generate excitation signals at the same frequency and amplitude but with a different energy level. Second, mixed-frequency waveform excitation allows to explore selective frequency response of the expected internal material distribution. Medical standards restricts the energy of the excitation signal and, as a consequence, a well controlled data acquisition procedure for electrical tomography is fundamental. The architecture design allows to incorporate frequency scanning capabilities on the device. The construction considers an FPGA reconfigurable processor for fine-grained control of the data acquisition process. This prototype is concealed to explore and select adequate excitation-sensing strategies for respiration monitoring.","PeriodicalId":288282,"journal":{"name":"2019 Applications of Electromagnetics in Modern Engineering and Medicine (PTZE)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132740863","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}

Fault current flow can cause thermal and dynamic harmful effects on the operation of power equipment. An ideal fault current limiter is required to have zero impedance at work currents and substantial impedance in short-circuit conditions. These requirements are met by superconducting fault current limiters which use the phenomenon of transition of a superconducting material from the superconducting state to the resistive state as a results of exceeding the critical current Ic of the superconducting material [1]–[3]. An inductive fault current limiter is a triple-winding construction consisting of two superconducting windings and one copper winding, which are magnetically coupled with each other. Both superconducting windings are wound simultaneously on one carcass, which allows to obtain a very large magnetic coupling coefficient between the windings, minimize the dispersion reactance of the limiter, which in turn minimizes the voltage at the limiter in the waiting state. The limiter is lightweight due to its coreless design and cryogenic cooling of the copper winding.","PeriodicalId":288282,"journal":{"name":"2019 Applications of Electromagnetics in Modern Engineering and Medicine (PTZE)","volume":"125 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116049604","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}
