Centroid and Moment of Inertia from mechanics of material by hibbler related ...

Centroids and moment of inertia are important concepts in mechanics. The centroid of a plane figure is the point where the entire area is considered to be concentrated. It is found by suspending the figure from different corners and finding the intersection point of vertical lines. The center of gravity is where the entire mass is considered concentrated. For uniform plane figures with no weight, the centroid and center of gravity coincide. The moment of inertia is a measure of an object's resistance to changes in rotation or bending and depends on the object's mass distribution and axis of rotation. It is calculated based on the object's area or mass distances from the axis of rotation.

Modeling and Structural Analysis of a Wing [FSI ANSYS&MATLAB]

In our study, analyzing aircraft’s wing with the old assumptions will not give an exact solution but
this solution (total deformation) changes according to the geometry of the cross-section of the beam, so
the total deformation of the beam may be greater or lower than the exact solution. In these two cases,
the solution is not acceptable as in the first case which the deformation is greater than the exact solution
will make more weight and cost, and Engineers design aircraft at minimum weight and less cost. But in
the second case which will make lower deformation than exact solution will be much risky as the aircraft
could fail at any time, and this case much dangerous because it threatens the life of people.

This document describes using MATLAB programming to analyze the slope and deflection of complex structure beams using the interpolation method and Euler-Bernoulli beam theory. It presents a method for calculating slope and deflection at any point on a beam subjected to multiple loads by using the principle of superposition. The document provides background on beam theory concepts like bending moment, radius of curvature, slope, and deflection. It also reviews previous work analyzing beams and plates with finite element methods or interpolation. Examples are given of calculating slope and deflection for different beam cases like a cantilever beam with a point load. The goal is to develop a MATLAB program to analyze complex beam structures without dependence on material properties.

STATIC ANALYSIS OF COMPLEX STRUCTURE OF BEAMS BY INTERPOLATION METHOD APPROAC...

In this article a MATLAB programming has shown which is based on the method of super position theory of a beam to investigate the slope and deflection of a complex structure beam. The beam is assumed and it is subjected to several loads in transverse direction. The governing equation
of slope and deflection of complex structure beam are obtained by method of super-position theory and Euler-Bernoulli beam theory. Euler-Bernoulli beam theory (also known as Engineer’s beam theory or classical beam theory) is a simplification of the linear theory of elasticity which provides a means of calculating the load carrying and deflection characteristics of beams.

Paper Title
Particle Swarm Optimization–Long Short-Term Memory based Channel Estimation with Hybrid Beam Forming Power Transfer in WSN-IoT Applications
Authors
Reginald Jude Sixtus J and Tamilarasi Muthu, Puducherry Technological University, India
Abstract
Non-Orthogonal Multiple Access (NOMA) helps to overcome various difficulties in future technology wireless communications. NOMA, when utilized with millimeter wave multiple-input multiple-output (MIMO) systems, channel estimation becomes extremely difficult. For reaping the benefits of the NOMA and mm-Wave combination, effective channel estimation is required. In this paper, we propose an enhanced particle swarm optimization based long short-term memory estimator network (PSOLSTMEstNet), which is a neural network model that can be employed to forecast the bandwidth required in the mm-Wave MIMO network. The prime advantage of the LSTM is that it has the capability of dynamically adapting to the functioning pattern of fluctuating channel state. The LSTM stage with adaptive coding and modulation enhances the BER.PSO algorithm is employed to optimize input weights of LSTM network. The modified algorithm splits the power by channel condition of every single user. Participants will be first sorted into distinct groups depending upon respective channel conditions, using a hybrid beamforming approach. The network characteristics are fine-estimated using PSO-LSTMEstNet after a rough approximation of channels parameters derived from the received data.
Keywords
Signal to Noise Ratio (SNR), Bit Error Rate (BER), mm-Wave, MIMO, NOMA, deep learning, optimization.

Properties of Fluids, Fluid Statics, Pressure Measurement

Properties of Fluids: Density, viscosity, surface tension, compressibility, and specific gravity define fluid behavior.
Fluid Statics: Studies pressure, hydrostatic pressure, buoyancy, and fluid forces on surfaces.
Pressure at a Point: In a static fluid, the pressure at any point is the same in all directions. This is known as Pascal's principle. The pressure increases with depth due to the weight of the fluid above.
Hydrostatic Pressure: The pressure exerted by a fluid at rest due to the force of gravity. It can be calculated using the formula P=ρghP=ρgh, where PP is the pressure, ρρ is the fluid density, gg is the acceleration due to gravity, and hh is the height of the fluid column above the point in question.
Buoyancy: The upward force exerted by a fluid on a submerged or partially submerged object. This force is equal to the weight of the fluid displaced by the object, as described by Archimedes' principle. Buoyancy explains why objects float or sink in fluids.
Fluid Pressure on Surfaces: The analysis of pressure forces on surfaces submerged in fluids. This includes calculating the total force and the center of pressure, which is the point where the resultant pressure force acts.
Pressure Measurement: Manometers, barometers, pressure gauges, and differential pressure transducers measure fluid pressure.

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.
