In every part of the world, there is a tremendous growth in digital literacy in the present era. People are trying to access internet-based applications with the use of digital machines. As a result, the internet as become a primary requirement for everyone, and most business transactions often take place conveniently across the network. On the other hand, intruders involved in making intrusions and doing activities such as capturing passwords, compromise on the route, collecting details of credit cards, etc. Many malicious activities are taking place over the network due to this intruding activity on the internet. The intrusion detection system (IDS) helps to find the attacks on the system and the intruders are detected. This paper has expected for an approach to develop IDS by using the principal component analysis (PCA) and the random forest classification algorithm. Where the PCA will help to shape the dataset by reducing the dimensionality of the dataset and the random forest will help in classification. Results obtained states that the proposed approach works more resourcefully in terms of accuracy as compared to other methods like SVM, Naïve Bayes, and Decision Tree.

This paper describes a model-based method for estimating the speed of an induction motor drive that does not have a speed sensor. Because of its less complicated implementation technique, the model-based approach is extensively employed. Vector Controlled Induction with No Sensors To get good dynamic performance, motor control is used. Studies on inverter switching techniques led to the creation of a bus clamped space vector modulation scheme, which has a direct impact on the performance of induction motor drives, particularly in sensorless applications. The modulation technique reduces motor current distortions, pulsation in torque, inverter losses and harmonics in the inverter thus, improvising the performance of the drive. Simulation analysis is performed on MATLAB platform and the results obtained prove the efficacy of Model based speed estimator and Bus Clamped Modulation analogy.

The traditional wired charging technique is inconvenient to transport. In order to function or charge, the units must be linked to power outlets. Moving the units takes time, energy, space, and personnel, making it a time-consuming and a costly process. Users' choice and equipment placement may be limited due to system configuration. Electrical surges and failures can cause damage to the wires. The wireless units, on the other hand, can be unplugged at any time if something goes wrong. This paper describes a Wireless Power Transfer system that charges a low-power device utilizing resonant inductive coupling. To properly distribute wireless power, it usually employs a number of transmitters because these transmitters can be employed in large numbers to capture as much energy as feasible also signal and connection losses are reduced. In the current simulated model we are using a 2-coil system because we are supplying the power to a low-power gadget. The circuit was conceived, simulated, prototyped, and tested successfully. It can be used to wirelessly charge a phone, charge a battery, and power medical devices, among other things. The design can work for a wide range of frequency and proves beneficial over certain conventional transmission system. The designed circuit was simulated on Simulink and the results were obtained.
