As the 2DEG well forms in the interface of two different bad gap material in HEMT is not infinite energy potential well. Thus there will be a probability of electron carriers appearing outside of the 2DEG well in the barrier layer where they scatter due to impurity. This scattering limits the performance of the HEMT device. Structural Change is based upon a new undoped AlGaN layer between channel and barrier layer in conventional HEMT to reduce the scattering. The impact of this structural change on AlGaN/GaN HEMT performances are compared with respect to the performance of conventional HEMT devices. For both devices, DC and RF performances are observed and results are considered for comparing their performance. Transconductance, drain current characteristics are the DC parameters of HEMT devices which significantly improved after adding the spacer layer. As well as transfer characteristics, output conductance increases significantly. For HEMT with a spacer layer, it is observed that the maximum cutoff frequency is 1.344 times of the HEMT device without a spacer layer. The maximum frequency of oscillation increases by 1.162 times with the addition of the spacer layer. At the same operating condition, the minimum noise figure of the HEMT device decreases after adding the spacer layer. These results prove that the RF performance of HEMT with spacer layer is much better than a HEMT without spacer layer & HEMT with this new device structure is more preferable for high-frequency operations.","PeriodicalId":239251,"journal":{"name":"2021 International Conference on Information and Communication Technology for Sustainable Development (ICICT4SD)","volume":"135 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115624997","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}

There is used trilateration technique to detect the submerged sensors and beacon is considered in six different positions. In this proposed model three sensors have been used. To find out the coordinates of the sensor nodes Cayley-Menger determinant is used for the proposed model. Here three mobile sensors and one beacon node that made six different volume tetrahedron shapes by making it in same volume through projection to apply Cayley-Menger determinant.

However, their availability depends on the climate so they cannot be a constant source of producing electricity. Considering all these aspects, water is considered a steady source for generating power. The main motive of the system, proposed in this paper, is to generate hydroelectricity by utilizing wastewater through the recycling process. Different chambers are provided with exclusive features to make the recycling process for getting reliable and sustainable energy. One motorized pump has been incorporated to maintain the constant water flow during the recycling process and this DC motor has been powered by the solar panel accordingly giving energy based on the utilization of sunlight. By utilizing this prototype device, a succeeding amount of electricity can be generated as an output with continuous recycling of water. Approximately, 119.3 mA of electricity and 12.69 volts DC controlled output can be measured after the proper implementation of the project. Therefore, 1.51 watts of power is possible to generate by utilizing this prototype device. Furthermore, one of the main utilizations of this project is to install it in the mosques where ablution water will be used as a flow of source as this water is not too much contaminated. Thus it can be a possible source for generating hydroelectricity.","PeriodicalId":239251,"journal":{"name":"2021 International Conference on Information and Communication Technology for Sustainable Development (ICICT4SD)","volume":"13 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126045413","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}

Specially it becomes more challenging when trajectory data have to share serially after a specific interval. All the existing methods are not applicable for serial publication. Methods for serial publication is required because of dynamic behaviour of trajectory data. In a serial publication of trajectory data, two types of privacy guards must be provided. Firstly, privacy guards is to be used in each release. Secondly, there must be a privacy guard between two releases, so that individual trajectory is not identified. To fulfill these two objectives, we propose a model that consists of space shifting and spatiotemporal points clustering. In our model, two types of clustering approaches have been used. Each cluster meets the concept of k-anonymity that prevent record linkage attack in each release. After applying different clustering algorithm in each release, experimental result shows that our propose approach is able to mitigate intersection attack.","PeriodicalId":239251,"journal":{"name":"2021 International Conference on Information and Communication Technology for Sustainable Development (ICICT4SD)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133494703","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}
