It is the story of development of the new concept in analytics and story about friendship of 2 research scientists in very heavy time and occasions. Basic technical details is already published in earlier document. This document is one step beyond it.
The document discusses the basics of how lasers work, including:
- Lasers produce monochromatic, coherent light through stimulated emission of radiation.
- They require a population inversion between energy levels, which is typically achieved by "pumping" atoms to a higher energy state.
- When an atom in an excited state is stimulated by a photon, it drops to a lower energy state and emits another photon of the same frequency, phase and direction, amplifying the beam in the laser cavity.
1. The document discusses concepts related to radioactive decay including half-life, carbon dating, and nuclear reactions.
2. Half-life is defined as the amount of time it takes for half the nuclei in a radioactive sample to decay, and decay rates follow a pattern called a decay curve.
3. Carbon dating works by measuring the ratio of carbon-14 to carbon-12 in once-living organisms, since carbon-14 decays after death while carbon-12 remains constant.
The Compton effect was first demonstrated in 1923 by Arthur Compton, for which he received the 1927 Nobel Prize in Physics. It describes the scattering of high-energy photons by loosely bound electrons, resulting in a wavelength shift that cannot be explained by classical wave theory. Compton scattering is important in fields like radiobiology and material physics. In his experiment, Compton bombarded a graphite target with x-rays and measured the intensity and wavelength of scattered radiation at different angles, observing a wavelength shift that supported Einstein's photon theory over classical wave explanations of light.

The atom is the smallest part of an element and is made up of subatomic particles including protons, neutrons, and electrons. Protons and neutrons are located in the nucleus at the center of the atom, while electrons whirl around the nucleus. Protons have a positive charge, electrons have a negative charge, and neutrons have no charge. Gaining or losing electrons produces an electric charge and electricity. Ohm's law defines the relationship between voltage, current, and resistance in electrical circuits. Power is calculated by multiplying voltage by current and can be used to determine the wattage of a circuit.
This document contains a multiple choice exam on radiation physics concepts with 8 problems. Problem 1 has 3 parts testing understanding of exposure rate reduction by a shield, committed dose from tritium inhalation, and matching radiation quantities to SI units. Problems 2-7 test stochastic and deterministic effects, cell survival curves, definitions of the roentgen unit, photon interactions in a target, pocket chamber exposure measurement, and calculation of a particle's W-value from ionization chamber data. Problem 8 asks about remaining dose limits under ICRP60 after specified whole body and thyroid exposures.

Mass spectrometry is an analytical technique that produces spectra of the masses of atoms and molecules in a sample. It works by ionizing the sample molecules and separating the resulting ions based on their mass-to-charge ratio. Common components include an ion source, mass analyzer, and detector. Common ionization methods are electron impact, chemical ionization, electrospray ionization, and matrix-assisted laser desorption/ionization. Common mass analyzers are the quadrupole and time-of-flight analyzer, which separate ions based on stability in oscillating electric fields or flight time. Mass spectrometry is used to determine molecular structure and composition.
Spectroscopy uses electromagnetic radiation to obtain information about molecules that are too small to see. Infrared (IR) spectroscopy analyzes the vibrations of bonds in molecules, which absorb specific wavelengths of infrared light. Different functional groups have characteristic IR absorptions that can be used for structure determination. Mass spectroscopy determines molecular mass by ionizing molecules and analyzing the resulting molecular ions. UV-visible spectroscopy analyzes electronic transitions in molecules, which absorb specific wavelengths and can reveal properties like conjugation. Together these techniques provide essential structural information about organic compounds.
Spectroscopy is the study of the interaction of electromagnetic radiation in all its forms with the matter. The interaction might give rise to electronic excitations, (e.g. UV), molecular vibrations (e.g. IR) or nuclear spin orientations (e.g. NMR). Thus Spectroscopy is the science of the interaction of energy, in the form of electromagnetic radiation (EMR), acoustic waves, or particle beams, with the matter.
Here in this article, the matter is studied in further detail.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

BASIC IDEA : EM wave is going through the solution of ions or molecules with dipol-moment.
Wave which is not react to any molecule or ion is Standing Wave and it goes through the
solution and gives its signal on the otput.
Another waves interacting with ions or molecules and it causes disorder of amplitude and
frequency disorder which can be registred on the output - osciloscop.
Disorder of frequency is related to e/m of ion or molecule.
By measuring of frequency disorder, we find out what ion or molecule is in the work wessell
and how many of it is in the wessell (how much is its concentracion).
3. 6
For compound NaCl, there would be 3 signals, for Na+, Cl- and one signal of the solvent (standing
wave). All the other signals would be caused by superposition of those 3 signals and they would
be bad sound (noise).
PROBLEM : Find inuf mechanicly weak wave to interact with the ions and compounds and inuf
strong to arrived to the receive antenn.
The solution to this problem is to find wave with right frequency, energy and wave lenght.
All of this parameters shoud be close to energies in ions or molecules and close to its wave
lenghts.
MODS OF APARATUS WORKING
Now we ilustrated on how many ways we can use our aparatus.
1. Shooting on one choosen frequency
2. Impuls shooting
3. Resonante shooting
4. Multichannel resonante shooting
4. 6
In text untill now , shooting with one choosen frequency has been described.
If we have an rectangle impuls on the deliver antenn, we can get an range of
frequencies in which are every resonante and the most of excited status of all ions and
compounds, so all we have to analize is their relaxation on the receive antenn.
Every ion or molecule has its own energy levels. If we know energy levels of our analyt,
we can use waves which energy is similar to energy difference beetween two diferente
levels in ion or molecule so they will resonate with our waves.
We can shoot some molecule with its frequency of vibration.
In this case, we will be sure which ion or molecule is in wessell and by measuring of
signal strenght- we can established its concentracion.
5. 6
If we have mix of compounds or ions, we can use multi channel resonante shooting.

Measuring that need to be done for catching relations to e/m.
1. Chlorides of 1, 2, 3 grupes by growing atomic and mass number of metal.
2. M Cl2 sol
3. Innorganic acides- HA, H2A, H3A
4. Innorganic bases- MOH, M(OH)2, M(OH)3
5. Complex compounds
6. Organic compounds in grupes by growing mass.
6. 6
Because of all this with waves and compounds in wessell is happening in real conditions, it may
be that the signals are too weak, so beetween osciloscop and receive antenn, we must add an
amplifier. With amplifier, shema of our WAVE ANALYZER is complete.
This document is original idea of author.
It is dedicated to all scientists of chemistry, phisycs and electrotechnics who has some unrealised
ideas. Don t wait, if You have inuf money, You can optimize my idea and built the wave
analyzer.
Since 2014 to 2017, I have been searching the company or people that could help to wave
analyzer looks the light of day.
Someone did not have inuf money, someone did not have time to help me, but some people
have stolen this idea and thanks to them, today, there are some analyzers which use principles
that I have used here. But it is not the end of idea about waves.
There is still inuf space to adopted this analyzer to work in medicine, cause it uses only the
electricity but not the chemicals. So, in the future, blood and urine and another analyses in
medicine should be cost less.
