E-Voting For Universities Using Face Recognition
No full textThis report describes an online voting system designed to meet the needs of colleges and universities. Voting is a widely spread, democratic way of making decisions and can be used for electing student presidents and class representatives at the college level. The main objective of the proposed system is to develop a more secure and user-friendly voting system compared to the existing methods. The process of voting is critical in terms of safety and security. The proposed system allows the voters to scan their faces, which is then matched with the already saved images within the database. There is a high chance that the voter's choice to be revealed in the traditional system, which is not the case in this proposed system. By using face recognition, it provides enough security to eradicate the dummy votes. The system also provides clear visualization of data regarding the percentage of total votes cast, the percentage of votes each party secured, and the final winner in the election
Based on PV's New Control Strategy A Fuzzy Logic Controller Is Used To Track Power Oscillation Damping
No full textIn order to dampen power oscillations (POD) in transmission networks, this paper provides a novel control of a PV solar system as a STATCOM, or PV-STATCOM. It is suggested that the solar farm temporarily (few tens of seconds) stop generating real power in response to power oscillations caused by system disturbances and instead use its complete inverter capacity as a STATCOM for POD. Power oscillations are dampened as soon as they occur, and the solar farm gradually returns to its pre-disturbance output level. Faster restoration is possible because of this method rather than the grid codes. During the night, the entire inverter capacity of the solar farm performs POD. MATLAB simulations indicate that the suggested control increases power transfer capacity significantly and continuously in systems that exhibit both local inertial and inter-area oscillatory modes. To provide POD at the same location, the proposed PV-STATCOM is 50-100 times less expensive than an analogous STATCOM. POD (power outage detection) is a new business prospect for solar farms that can save transmission companies money. In order to regulate pv-statcom more effectively, this paper utilises fuzzy logic control. MATLAB/SIMULINK was used to analyse the data
Efficient Authority Verification and Ranked Multi Keyword Search in Cloud
No full textUnder the single owner concept, encrypted cloud data has sparked various research projects. In fact, however, most cloud servers do not serve a single owner; rather, they enable several owners to share the benefits of cloud computing. The problem of recovering encrypted data from the cloud is perplexing. For recovering scrambled data from the cloud, a variety of search procedures are used. This work revolves around a set of keyword search instruments applied to encrypted data, resulting in great data recovery proficiency. Because many believe that sensitive data must be scrambled before outsourcing to cloud servers in order to ensure client data security, searching through encrypted data is a method of remarkable interest for the cloud computing moment. Strategies from multiple spaces are used to provide a productive and secure search technique over scrambled data. Keyword search, it is assumed, is the finest way for searching encrypted data in the Cloud. It is more productive than searching for a single term

Secure File Allocation in Cloud Storage Using Audit Services and Deduplication
No full textData de-duplication is a method of getting rid of duplicate copies of data and has typically been used in cloud storage to reduce the amount of data stored and transferred. However, despite the likelihood that a document is requested by a huge number of clients, there is only one copy of every file stored in the cloud. De-duplication framework hence improves storage use while lowering constant quality. Additionally, when clients outsource their sensitive data to the cloud, security for that data is put to the test. In order to address the aforementioned security issues, the main goal of this study is to codify the concept of an adequate reliable deduplication architecture. In this paper, new distributed deduplication frameworks with improved unwavering quality are provided, in which the data chunks are sent via various cloud servers. Cloud lessens the burden of storing and maintaining the enormous amounts of data. The issues of unwavering quality and security concerns are brought up by external cloud storage. Deduplication and integrity auditing problems are partially caused by the current framework. The main objective of this study is to achieve data integrity and deduplication in order to maintain the security and soundness of our system. With the aid of a guide lessen system, calculating times for data transferring and downloading were slashed in earlier work. Clients' private information is typically more safe, thus this uses encryption to increase security
Analyses of Stability and Power Flow in a Versatile Decentralized Generation System Using UPQC
No full textAn allocated generation machine that includes a single-level photovoltaic (PV) machine built into an integrated power quality conditioner (UPQC) is shown in this work. The UPQC serves as a bidirectional link between the DG system and either the grid or a micro grid. DG systems enable active power-line conditioning by injecting solar array-generated energy into the grid. A shunt inverter can be used to form an ac grid in islanded operation whether or not a power storage device is used. The PV-UPQC power flow must be thoroughly evaluated in order to gain a clear understanding of the system's overall performance and how the power converters should be formatted. This is why sizing curves are stated and introduced. Series and parallel inverters can be used to regulate and/or lessen the amount of power they process. For reducing conventional harmonic distortion, an Artificial Neural Network (ANN) controller has been proposed in this study (THD). A thorough study of the PV-UPQC functioning reveals that inverters are powered by active power flow, which is consistent with the findings of the radical expertise. As a result, Dynamic Response's performance can be examined using simulations
Solar Photovoltaic Water Pumping System Utilizing An BLDC Motor Drive
No full textThis research describes a cost-effective BLDC motor-driven solar photovoltaic (PV) water pumping system. We're working with a dual stage power conversion here with this solar PV water pump setup. To get the most power out of a solar PV array, the duty ratio of a DC-DC boost converter is adjusted at the first stage. By adjusting the motor speed, the DC bus voltage is kept at a constant level. This regulation reduces motor losses due to the drop in motor currents at a higher voltage for the same power injection as a result of this regulation. Using an INC-based maximum power point tracking (MPPT) control method, the duty ratio can be controlled. Models and simulations of the proposed system's performance have been done in great detail. The speed sensor/encoder is no longer necessary with scalar control. Motor current sensors are also no longer required. An additional speed feed forward term in the control scheme enhances the dynamics even further. The pump's constant variation is not a problem for the proposed control method. BLDC motors, which are more efficient and quieter than DC motors, are used in our suggested system. Maximum PV generator power loss is well matched to the BLDC motor's load characteristics. Analyzed are the MATLAB/SIMULINK results for several DC-DC converter topologies
