A synchrotron is a large machine that uses powerful magnets and radio waves to accelerate electrons to near light speed. As the electrons are deflected by magnetic fields, they emit extremely bright light across the electromagnetic spectrum. This synchrotron light is channeled to experimental stations where it is used for research in fields like medicine, materials science, and biology due to its high intensity and tunable wavelengths.
X-ray fluorescence (XRF) spectrometry is a technique used for elemental analysis. There are two main types of XRF spectrometers: energy-dispersive (ED) and wavelength-dispersive (WD). ED spectrometers use a detector to measure the energy of emitted X-rays, producing a spectrum. WD spectrometers use crystals to diffract and measure wavelengths of emitted X-rays. XRF can be used to identify elements in materials like metals, glass, ceramics, and paintings.
This document provides information about SEM (scanning electron microscope) and FTIR (Fourier transform infrared spectroscopy). It describes the key components and workings of an SEM, including the electron gun, vacuum chamber, lenses, sample chamber, and detectors. It also outlines sample preparation steps and advantages/disadvantages of SEM. For FTIR, the document discusses the interferometer component, types of detectors, advantages of higher signal-to-noise ratio and resolution, and limitations of its small sampling chamber size.
Radiography is a widely used non-destructive testing method that uses X-rays or gamma rays to detect internal flaws in materials. It works by placing an object between a radiation source and sensitive film - denser areas will block more radiation from reaching the film. The resulting variations in darkness on the film can reveal thickness changes, cracks, or other discontinuities inside the material. While radiography is useful for inspecting hidden internal areas without dismantling parts, it also poses health risks due to radiation exposure. Proper technique selection and experienced interpretation are required to obtain useful results from radiographic testing.
X-ray crystallography uses X-rays to determine the atomic structure of crystals. Crystals are bombarded with X-rays, which diffract upon contact with the atoms in the crystal. The angles and intensities of the diffracted X-rays are measured to deduce the positions of atoms in the crystal. This technique is useful for visualizing protein structures and identifying unknown crystal structures. It involves growing a crystal, exposing it to X-rays, and computationally analyzing the diffraction pattern to produce an atomic model of the crystal structure. X-ray crystallography has applications in characterizing polymers, assessing metal fatigue, and soil classification.
Wilhelm Roentgen discovered X-rays in 1895 while experimenting with electron beams. He noticed a fluorescent screen glowing near his vacuum tube and saw the silhouette of his wife's bones when she placed her hand in front of the tube. X-rays are produced when electrons collide with metal and knock out inner shell electrons, emitting high energy electromagnetic waves. They can pass through objects at different levels depending on density and are used in medical imaging like radiography.

X-ray crystallography uses X-rays to determine the atomic structure of crystals. It works by firing X-rays at crystalline samples and analyzing the diffraction patterns. This allows researchers to visualize protein structures and identify unknown crystal structures. The key steps are obtaining a suitable crystal sample, exposing it to X-rays, and computationally analyzing the diffraction data to produce an atomic model of the crystal structure. Common applications include determining molecular structures, characterizing polymers, and assessing the crystallinity and degradation of materials.
X-rays are a form of ionizing radiation that are used in diagnostic imaging to identify fractures, detect diseases like cancer, and examine internal structures. An x-ray tube produces x-rays by accelerating electrons at a metal target. X-rays are penetrating and can pass through tissues to form radiographic images. Radiologists use x-rays to examine bones, teeth, organs and tissues. While low dose, repeated x-ray exposures increase cancer risks, so the diagnostic benefits are weighed against risks in each case. Shielding with lead and distance from the source reduce radiation exposure for patients and medical staff.
X-ray crystallography uses X-ray diffraction to determine the atomic and molecular structure of crystals. Monochromatic X-rays are generated by a cathode ray tube and directed at a crystalline sample. The regular arrangement of atoms in the crystal causes the X-rays to diffract into specific patterns determined by Bragg's law, providing information about the crystal structure. X-ray diffraction is widely used in fields like biochemistry, materials science, and engineering to study the structure of molecules, crystals, and solid materials.

Applications of artificial Intelligence in Mechanical Engineering.pdfAtif Razi
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.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

8. The cathode means the negative electrode in the tube, which is a filament It
is made of tungsten, which means a filament, which is the ray film. The
anode, which is the positive pole of the ray tube. It is a metal target and is
tilted at a certain angle to the axis of the negative pole. The reason for its
tilt is that when the electrons coming from the cathode collide with the
anode, rays will be generated, so the anode is tilted towards the opening
inside the tube for the rays to exit. It is preferable to The anode is rotating
in order to increase the area of contact with it and for the purpose of
cooling. There is oil between the metal cover and the glass cover for the
purpose of cooling and increasing electrical insulation.

How it works: Connecting the tube to a power
source to the lever transformer, a high current of
electrons will be generated inside the tube with
the cathode, which will move towards the anode
and collide with it. The electrons, as a result of
the high heat generated, will be transformed into
rays and exit from the designated hole in its glass
cover, which is located below the anode, to the
patient and to the targeted organ. The remaining
rays inside the tube are absorbed by the lead-
lined inner wall
