Electron backscatter diffraction (EBSD) is used to measure crystal orientations from crystalline samples. EBSD allows for the measurement of 1) crystallographic texture, 2) grain orientation, 3) grain shape, and 4) local deformation structure from extremely rich data sets. Establishing consistent coordinate frames between the sample, crystal structure, and diffraction pattern is important for confident use of EBSD orientation data. A natural choice is the gnomonic projection, which transforms polar angles into radial distances measured from the pattern center. This defines a two-dimensional gnomonic coordinate system on the detection plane.

Presentation EBSD.pptx
Electron backscatter diffraction (EBSD) is a technique that can rapidly measure the orientations of crystals in a sample. EBSD uses automated software to analyze diffraction patterns produced when electrons hit the sample. This provides data on texture, grain orientation, grain shape, and deformation structure. However, there can be accuracy issues when linking crystal orientations to microstructural features due to differences in microscope and software setups and crystal symmetries. Establishing consistent frames of reference between the sample, crystal structure, and diffraction patterns is important for confident use of the orientation data.

Introduction to material science What kind of analyses methods will you take to examine the
lattice constants surface morphology with 1-10 mu m dislocation preferred orientation?
Solution
a) For lattice constant X-ray diffraction (XRD) is the best technique to analyse.
The atomic planes of a crystal cause an incident beam of X-rays to interfere with one another as
they leave the crystal. This phenomenon is known as X-ray diffraction. X-ray diffraction has
been in use in two main areas, for the fingerprint characterization of crystalline materials and
determination of their structure. Each crystalline solid has its unique characteristic X-ray powder
pattern which may be used as a “fingerprint” for its identification.
b) For surface morphology Scanning electron microscopy (SEM) is the best technique to analyse.
Scanning electron microscope is an instrument where entire primary electron beams emitted
from an electron source are scanned on sample and a scanning image is obtained from a
detection signal produced by secondary particles generated from the sample. Scanning electron
microscope actually capable of obtaining a scanning image with high spatial resolution within a
low acceleration voltage region
c) For dislocation Weak-Beam Dark-Field is the best methdo to analyse.
d)For orientation Geiger counter xray spectrometer is the best device to use..
Electron Diffraction Using Transmission Electron Microscopy
Electron diffraction via the transmission electron microscope is a powerful method for characterizing the structure of materials, including perfect crystals and defect structures. The advantages of elec- tron diffraction over other methods, e.g., x-ray or neutron, arise from the extremely short wavelength (≈2 pm), the strong atomic scattering, and the ability to exam- ine tiny volumes of matter (≈10 nm3). The NIST Materials Science and Engineer- ing Laboratory has a history of discovery and characterization of new structures through electron diffraction, alone or in combination with other diffraction methods. This paper provides a survey of some of this work enabled through electron mi- croscopy.

X-ray diffraction (XRD) is a technique used to analyze the crystal structure of materials. It works by firing X-rays at a crystalline sample and measuring the angles and intensities of the diffracted rays. Bragg's law explains why certain crystal structures scatter X-rays at specific angles. There are several methods for XRD including Laue, rotating crystal, and powder methods. XRD is widely used to identify unknown materials and determine structures of molecules, crystals, and thin films. Its applications include material science, mineralogy, and structural biology. Limitations include only being able to detect about 2% of impurities in mixed samples.
X-Ray Diffraction Technique
X-ray diffraction is a non-destructive technique used to identify crystalline materials by analyzing the scattering pattern of X-rays hitting a sample. Crystalline materials consist of atoms arranged in a regular repeating pattern that causes X-rays to diffract in specific directions. The diffraction pattern is compared to known patterns to determine the sample's structure and composition. X-ray diffraction is used in fields like solid-state physics, biophysics, and chemistry to study materials at the atomic scale.
Corneal topography and wavefront imaging
Corneal topography and wavefront analysis are imaging tools used to evaluate the cornea and refractive errors. Corneal topography measures the shape and curvature of the corneal surface using reflected placido rings, while wavefront analysis captures aberrations of the entire optical system using a Hartmann-Shack device. Both tools are useful for screening refractive surgery candidates and managing conditions like astigmatism and ectasia. Key information provided includes corneal curvature maps, aberration measurements via Zernike polynomials, and detection of irregularities like keratoconus.
X ray diffraction
X-ray diffraction is a technique that uses X-rays to determine the atomic and molecular structure of crystals. When X-rays hit a crystal, they cause the atoms to diffract into specific patterns determined by Bragg's law. By analyzing these diffraction patterns, information about the crystal structure such as lattice parameters and spacing between atomic planes can be determined. Common applications of XRD include identifying materials and determining their purity, structure, and properties.
Angular and position stability of a nanorod trapped in an optical tweezers
The document summarizes the analysis of angular and position stability of a nanorod trapped in an optical tweezers. It computes the optical trapping forces and torques on a nano-cylinder using T-matrix and radiation stress integration approaches. The results show that lateral forces are several times stronger than axial forces, and lateral torques are 1-2 orders stronger than end-face torques. Torques due to surface stress are much stronger than spin torques. The analysis explains why low aspect ratio nanorods are stably trapped normal to the beam axis.

EBSD uses electron diffraction patterns (Kikuchi patterns) formed via backscattered electrons in an SEM to determine the crystallographic orientation of materials. The sample must be tilted to around 70 degrees to optimize the diffraction pattern resolution. Kikuchi band positions are indexed using their angles and spacings compared to reference diffraction data to determine the crystal structure and orientation at each measurement point. Automated analysis uses Hough transforms to detect band positions in Hough parameter space and calculate orientations by comparing interplanar angles to reference crystal structures. Tilting and beam conditions must be optimized to ensure high resolution diffraction patterns for accurate microstructure analysis.

This document describes a new robust fixed rank kriging (R-FRK) method for improving the spatial completeness and accuracy of satellite sea surface temperature (SST) products. The R-FRK method addresses two key issues: 1) it allows for dimension reduction kriging to be applied to satellite SST data over irregular regions, and 2) it incorporates a data-driven bias correction model to address systematic biases in the satellite SST measurements. The method is applied to Moderate Resolution Imaging Spectroradiometer (MODIS) SST data from 2003 and 2010. Validation using drifting buoy observations shows the method produces spatially complete SST fields with high accuracy.

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.

Blood finder application project report (1).pdf
Blood Finder is an emergency time app where a user can search for the blood banks as
well as the registered blood donors around Mumbai. This application also provide an
opportunity for the user of this application to become a registered donor for this user have
to enroll for the donor request from the application itself. If the admin wish to make user
a registered donor, with some of the formalities with the organization it can be done.
Specialization of this application is that the user will not have to register on sign-in for
searching the blood banks and blood donors it can be just done by installing the
application to the mobile.
The purpose of making this application is to save the user’s time for searching blood of
needed blood group during the time of the emergency.
This is an android application developed in Java and XML with the connectivity of
SQLite database. This application will provide most of basic functionality required for an
emergency time application. All the details of Blood banks and Blood donors are stored
in the database i.e. SQLite.
This application allowed the user to get all the information regarding blood banks and
blood donors such as Name, Number, Address, Blood Group, rather than searching it on
the different websites and wasting the precious time. This application is effective and
user friendly.

CRYSTAL ORIENTATION & EBSD TECHNIQUE.docx
- 1. Electron backscatter diffraction (EBSD) is a common laboratory based tool used to measure crystal orientations from crystalline sam-ples. The emergence of the technique can be traced to rapidimage anal-ysis (or) patternanalysis routines to produce extremely richdata sets that can be interro- gated for 1. crystallographic texture, 2. grain orientation, 3. grain shape, and 4. local deformationstructure. Frames of reference Establishing a consistent coordinate frame, with appropriate trans- formations between the sample, the crystal structure, and the diffrac- tion pattern is at the heart of successful and confident use of EBSD orientation data. A natural choice of coordinate system is based upon the gnomonic projection used to capture the angular diffraction data on a flat phos- phor screen, starting with the source point at the electron beam position on the sample, and the central Z-axis of the gnomonic projection meet- ing the detector plane at the point that is called the “pattern centre” (PC). The gnomonic projection transforms polar angles θ into radial dis- tances ρ = tan (θ) measured from the pattern centre. This is why, for the detector plane, we define a gnomonic, two-dimensional (Xg, Yg) coordi- nate system with (0 The gnomonic coordinate system is defined on the two-dimensional (Xd, Yd) detection plane in the three-dimensional detector coordinate system (Xd, Yd, Zd) in which we measure all distances on a common length scale (pixels, mm, or fractions of the pattern size). The Zd-axis points from a position on the sample towards the screen and calibrates the gnomonic coordinates via xg = xd/zd and yg = yd/zd.
