The inverted pendulum is an under actuated system and unstable system without a con-troller. In this paper modelling of an inverted pendulum is done using the Eu-ler-Lagrange equation for stabilization of it. The controller gain is evaluated through state feedback and reduced-order observer design techniques and the result for the dif-ferent initial conditions is compared. The state feedback controller is designed by Pole- placement technique for different desired pole locations. The simulation of the inverted pendulum based on reduced order pole placement design has been done on MATLAB/SIMULINK. It has been observed from the simulation result that the angular velocity and cart speed tracks the system response for different initial conditions by var-ying the desired pole location for the left-hand plane of the s-plane. In general, if some of the systems are unknown and the other state is known we can design using a re-duced-order observer for any physical system.

This paper presents simulation and design for the improvement of Li-ion battery ac-tive balancer using PI controller. The growing market for lithium ion (Li-ion) battery cells has made a positive impact towards electrical energy storage (EES) system throughout the advancing technological and scientific world. Balancing in a battery pack has become a main priority to avoid over-charging and over-discharging while also improving the Li-ion battery life. Unlike passive balancing, active balancing transfers the energy from one cell to another or controls the cell’s output, thus im-proving its efficiency. This paper presents how previous work was accomplished by many scholars in order to avail themselves of the active balancing project. A cell model was shown in this paper that was built based on energy transfer circuit theo-ries. A capacitor(C), inductor (L), MOSFET (M) and Diode (D) were used in the circuit build in order to balance the cells of different State-of-Charge (SOC). A PI controller was added with circuit to improve the voltage efficiency. After adding PI controller, the voltage balance of the cell was seen improved.

Machine Learning is a type AI (also known as Artificial Intelligence) that makes the pc or computer to act like individuals and learn more as they experience additional infor-mation from their client or user. So here in this report we got basic introduction about machine learning like actually what is it, what are its use, how it works, languages for coding, value of python for machine learning, and many more things. As python is ma-jorly used for machine learning, so we discussed about its use and its libraries. Thereaf-ter, we discussed about the categories in machine learning, i.e., supervised learning, un-supervised learning, semi-supervised learning and reinforcement learning. After this discussion we got a glimpse of some basic pros and cons of machine learning in artificial intelligence. After that we discussed about basic implementation formats of the algo-rithm in machine learning. Then we discussed about some majorly used applications of machine learning which are trending nowadays and has a great demand in today’s market. At the end we came to know about the future scopes in machine learning and concluded it.

Nmap is inbuilt in Kali Linux that is utilized by the organization to identify the weakness and remediate it. There are different sorts of subtleties that Nmap offers in the wake of filtering the objective. The data expressed in the manuscript can be utilized comprehend the idea of what Footprinting is, what hackers search for to Footprint, and how to shield against it. Nmap is a free and open-source utility for network disclosure and security examining. Numerous frameworks and organization heads additionally find it valuable for errands. In this paper, the study is conducted on the utilization of NMAP for the footprinting. The cloudflare server is utilized for the study. The suggestions on are pro-vided to avoid the footprinting. The results of the study will be helpful to avoid the foot-printing.
