Every field of engineering, technology, and real-time management has IoT applications such as transportation, agriculture, healthcare, manufacturing, wearable, smart grid and energy saving, smart home, smart management systems, etc. Also, AI has captured wide-area applications in the automobile industry, surveillance, security, education, entertainment, gaming, e-commerce, portable devices, robotics, biomedical instruments, etc. Electrical and electronic devices are used in IoT-based applications. They are required efficient energy to operate for a long time effectively. These types of devices required offline and online energy storage devices that charge on time or require less recharge. The supercapacitor has a high capacitor, rapid charging/discharging cyclic rate, cost-effective and eco-friendly. Our objectives are to study supercapacitors for providing energy and power supply backup to IoT devices. Electronic devices mainly operate on dc signals and electrical instruments work on signals. The supercapacitor plays an important role to supply energy which stores an extremely large amount of electrical charge. It is the future of batteries and replaces the old bulk batteries with tiny high-performance flexible sustainable supercapacitors.","PeriodicalId":14343,"journal":{"name":"International Journal of Research in Engineering and Applied Sciences","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136375627","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}

Consequently, their radiation patterns are unipolar and produce deep nulls in the upward direction. Such patterns will cause severe blind spots for the aircraft above and below this plane, which is undesirable for avionics networks. [1] To solve this problem, a dielectric resonator antenna (DRA) is attached to the blade antenna and thus a different design is formed. In this paper a rectangular DRA is used to illustrate the main idea.The antenna is housed inside the aerodynamically designed radome to reduce air drag (large dome-shaped structures which protect the radars from the bad weather conditions but at the same time allow the electromagnetic signals to be received by the radar without any distortion or attenuation). [11] An air core coil is also provided for DC grounding proposes. The antenna configuration is first optimized using HFSS based Ansys Electronics Desktop Student 2021 R2 simulation software and latter practically implemented. The comparison of simulated results is also presented in this paper.","PeriodicalId":14343,"journal":{"name":"International Journal of Research in Engineering and Applied Sciences","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91384205","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 specific aspects that were analyzed in the study are as follows:a) Effect of coir % & elongation on OMC and MDD, b) Effect on Consistency of sample, c) Combined effect of cement and coir on compressive strength, d) Combined effect of cement and coir on tensile strength. The objective of this investigation is to determine the optimum value of stabilizer for rammed earth blocks that will improve their geotechnical and mechanical properties while also fulfilling the principles of sustainability. The experiment used 8% cement as a stabilizer and 8% coir as reinforcement in lengths ranging from 20 mm to 40 mm. Based on the results of the experiment, it was found that the characteristic dry compressive strength of the rammed earth blocks improves up to 1% coir of 20 mm length, and then gradually decreases as the length and percentage of coir increase. In addition, the strength ratio drops by about 3.05%–6.27% as the coir length increases from 20 mm to 40 mm.These results suggest that the optimum value of coir reinforcement for improving the mechanical properties of rammed earth blocks is 1% with a length of 20 mm. However, it is important to note that the sustainability of the technique should also be considered when determining the optimum value of stabilizer and reinforcement. Overall, the investigation demonstrates that the use of coir reinforcement along with cement stabilization can be an effective approach for improving the geotechnical and mechanical properties of rammed earth blocks. However, further research is needed to optimize the coir percentage and length to achieve the desired strength properties while ensuring sustainability.","PeriodicalId":14343,"journal":{"name":"International Journal of Research in Engineering and Applied Sciences","volume":" 44","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91413827","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}

Utilization of this high ash content coal is again a verychallenging task. Presently, gasification of high ash coals has not yet been in application due to the difficulties arising from the ash handlingprocesses. In this work an attempt was made to design a partially fluidized bed reactor that can handle 30 kg/hr coal as a feedstock. By usingan appropriate design procedure a complete design of a hybrid gasifier was studied deeply. The major aim of present research is todetermine the air flow rate for proper gasification, reactor diameter and reactor height, feed particle diameter, nozzle orientation and numbernozzles, reduction zone diameter and height. Experiments were carried out with feeding rate of 9.8 kg/hr with high ash content coal having39.83% ash. Satisfactory results have been found during experiments. The average producer gas generation during trial run was found to be29.8 Nm3/hr while average calorific value of producer gas was about 4500 kJ/Nm3. The work described here favours us understand the realgasification process for high ash content coal and thus facilitates the industrial application of gasification technology.","PeriodicalId":14343,"journal":{"name":"International Journal of Research in Engineering and Applied Sciences","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136375628","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}

Hence, in this research, the mechanical and dynamic properties of concrete with epoxy resin, epoxy-sand and silicon coated aggregates at different volume fractions ranging from 5 to 15 percent were experimentally investigated. The test results indicate that there are improvements in compressive strength of concrete ranging from 10 % to 18 %, in which a maximum strength was achieved by using 15 percent epoxy-sand coating. Furthermore, a 5 % epoxy resin coating, resulting in an increase in compressive and tensile strengths of concrete by 5% and there are enhancements in static and dynamic modulus of elasticity by 2.7 %. In general, concrete specimens made with aggregates coated with epoxy-sand have higher performance in compressive strength as compared to using aggregates epoxy and silicon coated aggregates.

They are however impaired by the characteristic nature of Distributed Renewable Energy Resources (DRERs). While DRERs and microgrids offer the advantage of sustainable energy generation and autonomous operation with respect to the traditional grid, their intermittency and unconventional characteristics due to deviation from the traditional power grid structures causes trepidation while opting for them. A cause of concern while employing microgrids in daily use is the peril to personnel and equipment during the occurrence of a fault. To mitigate severe loss of life and property, it is important to develop and design protection algorithms for microgrids. While there is a comparatively large pool of knowledge on AC microgrid protection, DC microgrid protection is challenging and is being focused on by researchers around the world. The unorthodox nature of these networks cause conventional protection algorithms to be unsuitable and make the protection of these microgrids tasking. The work in this paper aims to contribute to efforts in the protection of hybrid microgrids. While the work in this paper is limited to the DC side of the grid, the proposed algorithm is able to detect and identify the location of various types of DC faults. The algorithm is verified on a secondary radial hybrid microgrid and is further compared with existing DC protection algorithms on various performance parameters.","PeriodicalId":14343,"journal":{"name":"International Journal of Research in Engineering and Applied Sciences","volume":"73 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-04-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86253515","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}
