It is crucial to provide consumers quality electric power consistently. The frequency stability and power flow between different control zones are used to determine the standard power quality. As a consequence of which automatic generation control (AGC) is frequently employed to stabilize the power system. This work presents the AGC of a hybrid power system’s including thermal, small hydro power plant (SHPP), wind Turbine System (WTS) and Electric vehicles (EVs). The addition of electric vehicles to the utility grid, thermal plant generating rate constraints, and time delays in both control regions make the suggested power system more realistic and practicable. This makes the system a little more complicated, and it necessitates the use of a reliable controller to perform properly. Proportional Integral Derivative (PID) and Fractional Order Proportional Integral Derivative (FOPID) controllers are implemented in each region to control the system’s output power and sustain power balance. This leads to the frequency remaining near to its optimum value. To optimize the gain values of FOPID and PID controllers for AGC of the proposed system, Differential Evolution algorithm (DEA) is implemented. In Area1 and Area2 the system dynamics are assessed using a step load perturbation. The suggested control strategy using a FOPID controller enhances the frequency responsiveness of the system in terms undershoot, overshoot, settling time, steady state errors, and amplitude oscillations according to test results.

Pilot contamination has now been noted as a significant barrier to the accurate calculation of channel state information (CSI). A heterogeneous massive multiple-input-multiple-output(MIMO) cellular system has been addressed in this work, where the user number in each cell is presumed to vary. The users of each cell also continue to utilize the same pilots. As a result, the massive MIMO cellular system architecture opens the possibility of both intra-cellular and inter-cellular pilot contamination. Two sub-optimal methods are developed in this article to reduce the aforementioned pilot contamination, allocating similar pilot signals to different users in an orderly fashion depending on how much interference they are deemed to suffer. The intracellular pilot contamination was resolved in the first method before the inter-cellular pilot contamination. According to the second method, the inter-cellular pilot contamination was solved before the intra-cellular pilot contamination. The goal of each of these methods is to increase user fairness. As a result, users with higher channel gains are allocated the pilots having maximal interference, and vice versa. By contrasting the efficacy of the developed algorithms with current pilot contamination mitigation methods for different system parameters, it has been demonstrated how effective they are.

In this paper, a miniaturized quarter-mode substrate integrated waveguide (QMSIW) bandpass filter is designed and tuned using PIN diode. The Isosceles triangle based QMSIW is loaded with the circular CSRR to decrease the resonant frequency of the cavity. The QMSIW is designed over the RT/Duroid 5880 substrate whose thickness is 0.254mm. Two pole QMSIW is designed to get a simulated and further a slot is introduced on the top layer to control the position of transmission zero. The simulated value of the insertion and return loss are observed to be -0.61dB and 27.18dB respectively. A novel approach is developed for achieving tunability. PIN diode is placed in the slot and it’s ON and OFF variation are observed. With the ON state of the PIN diode the bandwidth of the filter increases by 580MHz.

With the worldwide adaptation of the internet, social network platforms have been rapidly engaging a vast global population. Such networks are subject to user engagement and interaction on various topics - social, political, economic, etc. The present work gathers such interaction between Twitter users over a period of 6 weeks, where the topic of interaction was restricted to the West Bengal state assembly election. The conversion of the acquired data to a node adjacency list was performed on the basis of the mention relationship between users. The network analysis was performed using a novel measure based on only the eigen-vector centrality of the users of the network, termed the NetworkPresenceFactor(NPF). The results reveal that network users affiliated with Party_1 had the most influence and presence over the dynamic network, followed by those affiliated with Party_2 and Party_3. The analysis of party-wise network influence also reveals a similar scenario. The weekly trends of presence reveal that Party_1 had a constantly reducing presence that was almost twice that of Party_2, while Party_3 started off with a minimum influence that peaked during week 6. On tallying, the results of our experiment differ from the ground truth. The authors conclude that the consideration of network structure alone (as in our work) is not sufficient in effective analysis of the network and the inclusion of the context of user interaction is essential for proper network analysis.

In this paper, we study the performance of non- orthogonal multiple access (NOMA) aided relay-assisted multi- casting vehicular communications. Specifically, we consider different road side units (RSUs) connecting vehicular groups to the base station. Each RSU transmits different information to its associated vehicles. In this scenario, we investigate the combined effects of nodes’ mobility, channel estimation error (CEE), and inter-RSU interference. Assuming Nakagami-m fad- ing environment, we derive precise expressions of the outage probability at both strong user and weak user end. Numerical and simulation results are provided to demonstrate the impact of various system/channel parameters and give useful insights into the system behaivor.

This paper introduces the design and analysis of a low-profile ultra-wideband (UWB) antenna with efficient performance characteristics for baggage scanning systems. A printed monopole antenna with a unique radiator shape is conceptualized from a usual rectangular radiator by smoothening the vertices and rotating it to 7 degrees to make it tilted. Further, a C-shaped partial rectangular ground plane is constructed in order to excite multiple resonance frequencies for increasing the impedance bandwidth of the antenna. The proposed antenna provides a wide operating bandwidth from 3.6-12 GHz which falls under the UWB band. The antenna geometry is developed on an FR4 substrate of thickness 0.8 mm and occupies a highly miniaturized surface of 11 × 18 mm2. Besides, perceived antenna also exhibits stable radiation characteristic with acceptable gain (~2.5-5 dBi) and radiation efficiency (~85 %). A baggage-scanning case study has also been replicated in the software environment to assess the scanning ability of the proposed UWB antenna. Performance analysis reveals that the designed antenna can be effectively used for security screenings in airports and public transport systems.

The objective of this work is to present an extension pq (EPQ) theory-based reference generation for a shunt active power filter (SAPF) operation under a dynamic loading scenario. Further, the current tracking controller is realized using a model predictive controller (MPC). The MPC provides optimal switching commands for the SAPF operation while predicting the model dynamics of the SAPF for admissible switching states only. Thus, the EPQ theory for reference current generation and MPC for current tracking control simplifies the control strategy adopted for SAPF operation with effective improvement in current harmonics as compared to the conventional control strategies. The proposed simplified control strategy is verified and validated through the MATLAB/Simulink-based results under linear-balanced, -unbalanced, and nonlinear loading scenarios.

Deep learning-based models have demonstrated exceptional performances in diverse fields. However, recent research has revealed that adversarial attacks and minor input perturbations may easily deceive DNNs. Graph Neural Networks (GNNs) inherit this weakness. An opponent can persuade GNNs to generate inaccurate predictions by influencing a few edges in the graph. It results in severe consequences of adopting GNNs in safety-critical applications. The research focus has shifted in recent years to make GNNs more robust to adversarial attacks. This article proposes GNN-Adv, a novel approach for defending against numerous attacks that disturb the graph structure during training. Experiments demonstrate that GNN-Adv surpasses current peer approaches by an average of 15 % across five GNN approaches, four datasets, and three defense techniques. Remarkably, GNNs-Adv can successfully restore their current performance in the face of terrifying, directly targeted attacks.

In this work, an Ag nanoparticle (NP) assisted TiO2 nanowire photoanode was deposited on a flexible ITO-PEN substrate using the GLAD technique at low temperature. The morphological, structural and optical properties of the samples are characterized. The Scanning Electron Microscopy (SEM) image reveals the successful deposition of Ag-NP assisted TiO2-NW on the ITO-PEN substrate. And, the measured thickness of the TiO2 nanostructure is ~ 10 µm. Furthermore, X-ray Diffraction (XRD) analysis shows the presence of anatase TiO2 and Ag-NP in the sample from the weak peaks. The optical analysis reveals that the deposition of TiO2-NW improves the absorption intensity in the UV and visible regions. Moreover, it is fascinating to observe that the absorption intensity is enhanced significantly after assisting Ag-NP at the top of the TiO2-NW. Therefore, the proposed method of deposition of Ag-NP assisted TiO2-NW using GLAD may be employed for developing novel photoanodes for flexible DSSCs and other optoelectronic applications.

In this paper, a 1.2V, radiation-hardened 14T SRAM (RHS-14T) memory cell is proposed to resilience the single event upset (SEU) and dual node upset (DNU) soft errors. The proposed RHS-14T memory cell obtained a 0% failure probability compared to the recently reported radiation-hardened SRAM cells like RSP-14T, RHBD-15T, SAR-14T, SIRI-14T, RH-14T, and SEA-14T with a maximum of 80 fC charge sharing is applied to the sensitive node pairs. The proposed RHS-14T exhibits 2.76x/ 1.43x/ 1.04x/ 1.63x times larger RSNM than RSP-14T/ SAR-14T/ RH-14T/ SEA-14T and 1.18x/ 1.04x/ 1x/ 1.13x/ 1.13x/ 1.21x times larger WSNM than RSP-14T/ RHBD-15T/ SAR-14T/ SIRI-14T/ RH-14T/ SEA-14T. Furthermore, 1.55x/ 1.14x/ 1.12x/ 1.47x/ 1.02x/ 1.54x times larger HSNM than RSP-14T/ RHBD-15T/ SAR-15T/ SIRI-14T/ RH-14T/ SEA-14T. Moreover, 2.06x/ 2.18x/ 1.12x/ 1.01x/ 1.72x/ 1.09x larger effective critical charge than RSP-14T/ RHBD-15T/ SAR-14T/ SIRI-14T/ RH-14T/ SEA14T when supply voltage is at 1V. Results and discussions shows that RHS-14T mitigates a single event upset in all the sensitive nodes. Furthermore, it achieves a better noise margin in terms of write and hold stability in worst-case PVT variations.

The proposed RHS-14T memory cell obtained a 0% failure probability compared to the recently reported radiation-hardened SRAM cells like RSP-14T, RHBD-15T, SAR-14T, SIRI-14T, RH-14T, and SEA-14T with a maximum of 80 fC charge sharing is applied to the sensitive node pairs. The proposed RHS-14T exhibits 2.76x/ 1.43x/ 1.04x/ 1.63x times larger RSNM than RSP-14T/ SAR-14T/ RH-14T/ SEA-14T and 1.18x/ 1.04x/ 1x/ 1.13x/ 1.13x/ 1.21x times larger WSNM than RSP-14T/ RHBD-15T/ SAR-14T/ SIRI-14T/ RH-14T/ SEA-14T. Furthermore, 1.55x/ 1.14x/ 1.12x/ 1.47x/ 1.02x/ 1.54x times larger HSNM than RSP-14T/ RHBD-15T/ SAR-15T/ SIRI-14T/ RH-14T/ SEA-14T. Moreover, 2.06x/ 2.18x/ 1.12x/ 1.01x/ 1.72x/ 1.09x larger effective critical charge than RSP-14T/ RHBD-15T/ SAR-14T/ SIRI-14T/ RH-14T/ SEA14T when supply voltage is at 1V. Results and discussions shows that RHS-14T mitigates a single event upset in all the sensitive nodes. Furthermore, it achieves a better noise margin in terms of write and hold stability in worst-case PVT variations.","PeriodicalId":183947,"journal":{"name":"2022 IEEE Silchar Subsection Conference (SILCON)","volume":"360 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120878174","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}
