Mems for space seminar presentation
Micro-Electro-Mechanical Systems, or MEMS, is a technology that in its most general form can be defined as miniaturized mechanical and electro-mechanical elements (i.e., devices and structures) that are made using the techniques of microfabrication. The critical physical dimensions of MEMS devices can vary from well below one micron on the lower end of the dimensional spectrum, all the way to several millimeters. Likewise, the types of MEMS devices can vary from relatively simple structures having no moving elements, to extremely complex electromechanical systems with multiple moving elements under the control of integrated microelectronics. The one main criterion of MEMS is that there are at least some elements having some sort of mechanical functionality whether or not these elements can move. In other words Microsystems are miniaturized integrated systems in a small package or more specifically, micro-sized components working together as a system and assembled into a package that fits on a pinhead. In the United States, these devices are referred to as microelectromechanical systems or MEMS. European countries referred to such devices as microsystems or MST. These two terms – MEMS and MST – are often used interchangeably. Microsystems are microscopic, integrated, self-aware, stand-alone products that can sense, think, communicate and act. Some systems can do all of these things, plus scavenge for power.

Fingerprint recognition
Fingerprint recognition is a biometric technique that uses fingerprint patterns to identify or verify individuals. It works by extracting minutiae points like ridge endings and bifurcations from scanned fingerprints and matching them against a database. The process involves fingerprint acquisition using optical or semiconductor sensors, minutiae extraction after preprocessing and thinning the image, and minutiae matching for verification or identification. Fingerprint recognition has applications in security systems and has advantages of high accuracy and small storage requirements, though it can be affected by dirty or wounded fingers.

INVESTIGATING THE USE OF IMPEDANCE PLETHYSMOGRAPHY FOR DETECTING DECREASED BL...
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.

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

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...
Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.
AI offers the capability to process vast amounts of data, identify patterns, and make predictions with a level of speed and accuracy unattainable by traditional methods. This has profound implications for mechanical engineering, enabling more efficient design processes, predictive maintenance strategies, and optimized manufacturing operations. AI-driven tools can learn from historical data, adapt to new information, and continuously improve their performance, making them invaluable in tackling the multifaceted challenges of modern mechanical engineering.

Accident detection system project report.pdf
The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

Fingerprint recognition
- 1. FINGERPRINT RECOGNITION PROFESSOR SHAHRAM TAHERI Made By: Muhammad Nouman Abbasi Mirza Taimoor Sultan Baig
- 2. FINGERPRINT RECOGNITION • Fingerprint recognition is one of the oldest and most researched fields of biometrics. • The configuration types are individually variable, but they vary within limits that allow for a systematic classification. indiamart.com
- 3. FINGERPRINT FORMATION Finger ridge configurations do not change throughout the life of an individual except. aceproject.org
- 4. FINGERPRINT SENSORS • Optical • Silicon Based Capacitive Sensors • Ultrasound • Thermal
- 5. OPTICAL SENSORS • An optical sensor converts light rays into an electronic signal. • Optical Sensors are used for contact-less detection, counting or positioning of parts. • Optical sensors can be either internal or external. • The measurands possible by different optical sensors are Temperature, Velocity Liquid level, Pressure, Displacement.
- 6. TYPES OF OPTICAL SENSORS There are different kinds of optical sensors. • Photoconductive • Photovoltaic cell • Photodiodes
- 7. ADVANTAGES No reference electrode is needed. No electrical interference. Can easily be replaced. No electrical safety hazards. Multi wavelength measurements. Potential for higher information content.
- 8. DRAWBACKS Appropriate reagent phases can be developed. Background ambient light. Limited dynamic range. Response times may be slow.
- 9. SILICON BASED SENSORS Its introduction in the late 90’s. Based on DC Capacitance, but some also use AC Capacitance. One plate of a capacitor, and the finger is the other. 8-bit grayscale digital image.
- 10. ULTRASOUND SENSORS The most accurate of the fingerprint technologies. Transmitted ultrasound waves and measures the distance. This is a technology with significant promise.
- 11. ADVANTAGES Capable of penetrating dirt and residue on the sensing plate. Overcomes the drawbacks of optical devices. Ability to overcome sub-optimal reading conditions. Virtually impossible to deceive an ultrasound system.
- 12. DRAWBACKS Equipment expense. Many cancers cannot be detected via an ultra sound. Not available everywhere. Preventing early diagnosis of the portion of breast cancer.
- 13. THERMAL SENSORS • A temperature sensor is a device used to measure temperature. • Thermocouples, RTDs, thermistors, and semiconductor based ICs/.
- 14. ADVANTAGES Electrostatic discharge. Temperature conditions as at room temperature. Deceive with artificial fingertips.
- 15. DRAWBACKS Image disappears quickly. The finger and the pixel array have reached thermal equilibrium. This can be avoided by using a scanning method but only a few pixels high.
- 16. PRINCIPLES OF FINGERPRINT ANALYSIS The fingerprint pattern, such as the print left when an inked finger is pressed onto paper, is that of the friction ridges on that finger. Friction ridge patterns are grouped into three distinct types
- 17. LOOPS • Recurve back on themselves to form a loop shape. • Loops account for approximately 60 percent of pattern types.
- 18. WHORLS • Form circular or spiral patterns, like tiny whirlpools. • There are four groups of whorls. 1. Plain 2. Central pocket loop 3. Double loop 4. Accidental loop • Whorls make up about 35 percent of pattern types
- 19. ARCHES • Create a wave-like pattern. • Arches make up about 5 percent of all pattern types.
- 20. LINE TYPES CLASSIFICATION Bifurcation Arch Loop Island Ellipse Tented Arch Spiral Rod Sweat Gland
- 22. FEATURE EXTRACTION • The human fingerprint is comprised of various types of ridge patterns. • Loops make up nearly 2/3 of all fingerprints, whorls are nearly 1/3, and perhaps 5-10% are arches
- 23. FEATURE ENHANCEMENT • The first step is to obtain a clear image of the fingerprint. • To improve the clarity of ridge and furrow structures of input fingerprint • Areas lighter than a particular threshold are discarded • Ridges are then thinned from 5-8 pixels Original Enhanced
- 24. TEMPLATE SELECTION • Matching accuracy of a biometrics-based authentication system relies on the stability. • Biometric data acquired from an individual is susceptible to changes introduced due to improper interaction with the sensor • The stored template data to be significantly different from those obtained during authentication Variation in fingerprint exhibiting partial overlap.
- 25. MATCHING ALGORITHM • Automatic Minutiae Detection ALGORITHM: • Compare the minutiae on the two images. • The figure alongside is the input given to the system.
- 26. • The next step in the algorithm is to mark all the minutiae points on the image. • Image is superimposed onto the input image. • Finally a comparison is made with the images in the database.
- 27. APPLICATIONS • Banking security - ATM security card transaction • Physical access control (e.g., Airport) • Information system security • National ID systems • Prisoner, prison visitors • Identification of criminals • Identification of missing children • Secure e-commerce (still under research)
