Different nonlinear devices like diodes, rectifiers, and furnaces are generating power fluctuation, voltage sag and swell concerns, load imbalance, voltage imbalance, and other power quality issues, which may be controlled by FACTS devices such as DVR, STATCOM, Active power filter, UPFC, and UPQC. In the present work, application of DSTATCOM in the distribution network to overcome power quality issues, meeting the reactive requirement of the load to raise power factor to unity are addressed. A novel Sinusoidal PWM (SPWM) control technique is employed to reduce the harmonics in the distribution network. It relies on weighted value convergence and is unaffected by carrier signal characteristics. In this paper, four different cases have been considered with varying supply voltages. The simulation results show that D-STATCOM works efficiently and offers very less THD for different power quality problem like voltage sag, swell, load imbalance, voltage fluctuation etc. The Voltage Source Converter is regulated using the Sinusoidal PWM method. The result indicates that the DSTATCOM and SPWM control technique is helpful for power quality improvement.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"96 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115436343","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}

Critical performance analysis of absorber has been carried out in terms of absorptivity, normalized impedance, polarization insensitivity, and angular stability. A graphene-metasurface absorber has been found to possess an absorptivity of 96% at 6.1 THz with a corresponding absorption bandwidth of 1.4 THz.

To strengthen electronic waste (e-waste) treatment and explore wideband absorber structure, perforated RASs are proposed and modelled with the magneto-dielectric properties of microwave heat treated e-waste composite. The investigation of proposed structures is carried out in 8.2 to 12.4 GHz (i.e., X-band). The thin and wideband single layer RAS is optimized with the help of multi-objective Jaya's optimization algorithm. As an outcome, a −16.8dB reflection coefficient (RC) is achieved in 2.4mm thick grid type RAS at 10.2 GHz exhibiting a −10dB bandwidth of 4.2 GHz. Furthermore, at a fixed optimized thickness, the proposed RAS is also examined against various oblique angles of incidence and found to be prominent. The full-wave simulation is utilized for the validation of optimized results and both are in good agreement with each other. The addition of a circular air gap in the structure regulates the composite EM characteristics at a higher frequency. It demonstrates that cavitation has magnificent advantages for the creation of wideband, lightweight, and low expense RAS for the stealth technology.","PeriodicalId":445427,"journal":{"name":"2021 International Conference on Control, Automation, Power and Signal Processing (CAPS)","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127005359","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}

Most of the vision applications deal with intensity-wise segmented frames as their raw input. The power of textural analysis along with conventional intensity-based processing can enhance the system's capability in a remarkable manner. To address the textural nature of the image and for imparting texture-dependent image restoration or enhancement fractional-order high-boost filtering (FoHBF) the framework is essentially relevant irrespective of the image domain.
