Sensors' coverage plays an integral role in all types of applications that utilize WSNs. In addition to maximizing the life of the network and consuming less energy, the better positioning of the sensors makes the sensors more effective and efficient. A meta-heuristic algorithm will be used to determine where wireless sensors should be placed to maximize the coverage of the area where they are deployed. As a part of our solution, we will utilize the Immune Plasma Algorithm (IPA), which transfers plasma or the antibody-rich part of the blood from one patient to another through a process of bypassing the immune system. This optimization algorithm will be used to determine the optimal solution to the maximum coverage problem. The results of the simulation will be compared with solutions found by one research using Artificial Bee Colony (ABC), an algorithm that models the foraging behavior of bees.","PeriodicalId":375340,"journal":{"name":"2022 9th International Conference on Electrical and Electronics Engineering (ICEEE)","volume":"104 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133443748","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}

Its ability to capture different contrasts within an exam session allows it to collect additional diagnostic information. However, such multi-contrast MRI exams take a long time to scan, resulting in acquiring just a portion of the required contrasts. Consequently, synthetic multi-contrast MRI can improve subsequent radiological observations and image analysis tasks like segmentation and detection. Because of this significant potential, multi-contrast MRI synthesis approaches are gaining popularity. Recently, generative adversarial networks (GAN) have become the de facto choice for synthesis tasks in medical imaging due to their sensitivity to realism and high-frequency structures. In this study, we present a novel generative adversarial approach for multi-contrast MRI synthesis that combines the learning of deep residual convolutional networks and spatial modulation introduced by an attention gating mechanism to synthesize high-quality MR images. We show the superiority of the proposed approach against various synthesis models on multi-contrast MRI datasets.","PeriodicalId":375340,"journal":{"name":"2022 9th International Conference on Electrical and Electronics Engineering (ICEEE)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134164783","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 primary concern for the operation of such advanced MTDC grids is to ensure the reliability and safety of the electrical equipment during dynamic and transient conditions following standard grid codes. This research work proposes a combination of different control strategies developed for MMC based MTDC systems to promote fault ride-through capability during three-phase transients and voltage dips. The proposed control architecture contains inner and outer control loops for MMC stations. Along with the different control strategies, the inherent energy available in the capacitors of submodules MMC has also been utilized, which ensures constant power delivery to the load system during three-phase transients & voltage dips and provides power oscillation damping (POD) with quick post fault recovery operation. The energy dimensions required for capacitors of each MMC station are calculated. The proposed control strategies have been validated with an experimental setup of a four-terminal MMC based MTDC system developed in the simulation environment. The proposed control strategies envision a robust fault ride-through capability with reduced oscillations and total harmonic distortion (THD). Such a method is more reliable for an MTDC system than the classical solutions, which are based on drawing increased current from the grid or using additional circuitries. Moreover, the proposed control strategies can work efficiently for any MTDC system as compared to previously presented solutions, which are restricted to two-terminal HVDC systems.","PeriodicalId":375340,"journal":{"name":"2022 9th International Conference on Electrical and Electronics Engineering (ICEEE)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125272449","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}
