2. Key monitoring devices discussed are oxygen analyzers, automatic blood pressure monitors, ECG monitors, ventilation monitors, pulse oximeters, capnography and temperature monitors. Peripheral nerve stimulation and depth of anesthesia monitoring are also covered.
3. The standards for monitoring published by the American Society of Anesthesiologists are described which require continual monitoring of the patient's condition during anesthesia.
Cardiac daignostic test
Cardiac diagnostic tests can be invasive or non-invasive. Common non-invasive tests include electrocardiography (ECG), echocardiography, nuclear heart scan, chest x-ray, cardiac CT scan, and cardiac MRI. ECG records the heart's electrical activity while echocardiography uses ultrasound to image the heart. A nuclear heart scan uses radioactive tracers to evaluate blood flow and pumping ability. These tests can diagnose conditions like coronary artery disease, heart failure, and past heart attacks. Invasive tests include cardiac angiography and intravascular ultrasound which use catheters and dyes to directly image the heart and blood vessels.

Literature Review
According to Isabel Morales’ research, the foot impedance plethysmography was carried out with two distinct kinds of electrodes, using 1mA/10kHz and finding the impedance of the foot.
In this study Piuzzi research is an ultimate technique selected that makes use of a current with a frequency of 50 kHz that is injected into the thorax of the subject using a couple of textile electrodes.
In this study of Ramkumar & Babu, blood flow was performed using a fuzzy logic toolbox with many different activities, measured before and after the 25 seconds of breath-holding activity. The plethysmographic waveform of forearm impedance can be used to analyze the changes in a heartbeat that are correlated with the changes in heart stroke volume.
Contribution
In this work we are investigating using multiple electrodes to see the additional data going to make testing easier.
Our research is primarily focusing on the amount of blood flow through the finger of the upper limb for diabetic patients.
Conclusion
The finger-simplified model was created in model geometry. A framework made up of five parts was used to build the finger. (i.e., skin, fat, artery, muscle, and bone)
The study includes COMSOL simulation results compared with experimental results to obtain the optimum parameters for this technique. The COMSOL simulation uses 4 electrodes in different positions with a current of 10mA giving the optimal frequency of 100Hz.
It was shown that multiple electrodes can be useful in obtaining impedance change.
This is useful because signals can not be obtained from one pair, or to further support the results.
The study was performed under normal resting conditions where an experimental procedure was set up to measure the impedance response from the finger.
Experiment results were not conclusive as more sensitive impedance analyzers are required.
This research will be helpful to find out the heartbeat using impedance plethysmography.

Fingerprint Recognition
Fingerprint Recognition
Fingerprint recognition is one of the oldest and most
researched fields of biometrics.
Some biological principles (Moenssens 1971) related
to fingerprint recognition are as follows:
Individual epidermal ridges and furrows have different characteristics for different fingerprints.
This forms the foundation of fingerprint recognition
The configuration types are individually variable; but they vary within limits that allow for a systematic classification.
Herein lies the basis for fingerprint classification.
The configuration and minute details of furrows are permanent and unchanging.

state space modeling of electrical system
Introduction
As systems become more complex, representing them with differential equations or transfer functions becomes cumbersome. This is even more true if the system has multiple inputs and outputs. This document introduces the state space method which largely alleviates this problem. The state space representation of a system replaces an nth order differential equation with a single first order matrix differential equation. The state space representation of a system is given by two equations :
The first equation is called the state equation, the second equation is called the output equation. For an nth order system (i.e., it can be represented by an nth order differential equation) with r inputs and m outputs the size of each of the matrices is as follows:
Several features: The state equation has a single first order derivative of the state vector on the left, and the state vector, q(t), and the input u(t) on the right. There are no derivatives on the right hand side. The output equation has the output on the left, and the state vector, q(t), and the input u(t) on the right. There are no derivatives on the right hand side.
q is nx1 (n rows by 1 column) q is called the state vector, it is a function of time A is nxn; A is the state matrix, a constant B is nxr; B is the input matrix, a constant u is rx1; u is the input, a function of time C is mxn; C is the output matrix, a constant D is mxr; D is the direct transition matrix, a constant y is mx1; y is the output, a function of time
Derivation of of State Space Model (Electrical)
To develop a state space system for an electrical system, they choosing the voltage across capacitors, and current through inductors as state variables. Recall that
so if we can write equations for the voltage across an inductor, it becomes a state equation when we divide by the inductance (i.e., if we have an equation for einductor and divide by L, it becomes an equation for diinductor/dt which is one of our state variable). Likewise if we can write an equation for the current through the capacitor and divide by the capacitance it becomes a state equation for ecapacitor
There are three energy storage elements, so we expect three state equations. Try choosing i1, i2 and e1 as state variables. Now we want equations for their derivatives. The voltage across the inductor L2 is e1 (which is one of our state variables) so our first state variable equation is
This equation has our input (ia) and two state variable (iL2 and iL1) and the current through the capacitor. So from this we can get our second state equation
Our third, and final, state equation we get by writing an equation for the voltage across L1 (which is e2) in terms of our other state variables

This paper describes a speed control device for generating electrical energy on an electricity network based on the doubly fed induction generator (DFIG) used for wind power conversion systems. At first, a double-fed induction generator model was constructed. A control law is formulated to govern the flow of energy between the stator of a DFIG and the energy network using three types of controllers: proportional integral (PI), sliding mode controller (SMC) and second order sliding mode controller (SOSMC). Their different results in terms of power reference tracking, reaction to unexpected speed fluctuations, sensitivity to perturbations, and resilience against machine parameter alterations are compared. MATLAB/Simulink was used to conduct the simulations for the preceding study. Multiple simulations have shown very satisfying results, and the investigations demonstrate the efficacy and power-enhancing capabilities of the suggested control system.

Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network
