Discrete cosine transform (DCT) is closely related to discrete Fourier transform. This is a separable linear conversion. It can be said that DCT is simpler and faster than DFT as well as FFT. DCT is suitable for extended periodic and symmetric sequences, while DFT is suitable for long periodic sequences. So DCTs are the equivalent of almost double-...

Texture analysis refers to the description of areas in an image with their texture content. Texture analysis attempts to determine visual qualities described in terms such as rough, smooth, silky, or uneven as a function of spatial variations in pixel intensity. This article shows how to identify different colors in angiolipoma tissue by analyzing...

Gibbs energy, G, is analogous to the Helmholtz free energy for changes that occur in closed systems at a constant temperature and a constant pressure. According to the second law of thermodynamics, for systems that react at constant temperature and pressure without the input of non-PV work, there is a general natural tendency to achieve the minimum...

In the paper, we combine an intelligent algorithm for recognizing letters in an image and analyze its steps for tumor extraction in an MRI image. Successfully identify the border of the tumor, determine the location tumor with a limited circle, and determine whether the tumor is present or absent. Tumors vary in shape, size, and location, and may a...

Recognizing items in cluttered scenes is a fundamental test that has recently been generally accepted by computer vision frameworks. In this paper, we use the intelligent pattern recognition algorithm in a jumbled image in MATLAB for computer vision of area detection in satellite imagery. In the examples used, we used two completely different regio...

In this research, we analyze three carbon compounds of methane, methanol and methanal using crystal maker software. The two compounds methane and methanol are structurally the simplest compounds in their chemical family, with methane being the simplest member of the alkane family and methanol (methyl alcohol) being the simplest type of alcohol. Met...

Angiolipoma is an unusually benign neoplasm composed of mature lipocytes mixed with abnormal blood vessels. In this paper, we used cellular tissue segmentation using an intelligent tissue filtering algorithm to identify tissue-based image regions containing thick-walled capillaries with fibrin clots, between mature lipocytes and fibrin septum, and...

In this paper, we used Color-Based Segmentation Using K-Means Clustering using an intelligent tissue filtering algorithm to identify tissue-based image regions containing thick-walled capillaries with fibrin clots, between mature lipocytes and fibrin septum, and HE angiolipoma spots. Our algorithm for segmentation on the image of tissue impregnated...

In this paper, we first tried to eliminate the hologram phase that was noisy with a random noise signal and then extract the PCA numerical phase of the human macrophage cell recorded in digital holographic microscopy (DHM) by algorithm (PCA) method. It is a fast and simple method based on principal component analysis: PCA breaks down phase maps of...

Optical microscopy is the most common research method in medicine and biology and development of related technologies has been developed over the years. In this article, we introduce the Hilbert phase microscope (HPM) and its applications in various fields. HPM is an off-axis QPI method similar to the DHM digital holographic microscope. HPM is spec...

Solar panels usually do not work with the thickness of an atmosphere: if the sun is at an angle to the surface The thicker the ground, the more effective it will be. Many of the world's major population centers are solar industries Across Europe, China, Japan, USA, and other places (including North India, South Africa And Australia and) are in temp...

By changing the contrast resolution of different images, we can obtain new information and a lot of data such as surface temperature and material type, etc. Sometimes the blind spots of images are corrected and edited in different software by different methods comes. Here we tried to examine the new images obtained by NASA telescopes in different w...

The activated sludge process was discovered in 1913 in the United Kingdom by two engineers, Edward Ardern and W.T. Lockett, who were researching the Manchester Corporation Rivers Department at Davyhulme Sewage Works. In 1912, Dr. Gilbert Fowler, a scientist at the University of Manchester, observed experiments being conducted at the Lawrence Experi...

In this paper, we introduce Hilbert phase microscopy (HPM) as a new method for quantitative phase extraction of transparent interfering samples. Then we extract the quantitative phase of the interference design of a transparent sample under an interference microscope using the Hilbert phase microscope technique. In the next step, we reconstruct the...

Section of a block of thermocol under a light microscope (bright-field, objective = 10×, eyepiece = 15×). The larger spheres are expanded polystyrene beads which were compressed and fused. The bright, star-shaped hole at the center of the image is an air-gap between the beads where the bead margins have not completely fused. Each bead is made of th...

Questions

Questions (14)
Question
Everyone is aware that COVID-19 has had a significant impact on international relations and communications, as well as scientific orientation. To what extent do you think this epidemic has affected scientific progress in various fields?
Question
How much does the existence of advanced laboratories and appropriate financial budgets and different support for a researcher's research affect the quality and quantity of a researcher's work?
Question
Since our universe is dominated by matter, what if there is another universe dominated by antimatter? What would an antimatter universe look like?
Concepts and physical relations in the world of antimatter like our world? If not, how might it be? Didn't matter and antimatter completely annihilate at the time of the Big Bang? Perhaps this antimatter still exists somewhere else? Otherwise where did it go and what happened to it in the first place?
share your guesses and theories with us.
Question
Arrow of time (e.g. entropy's arrow of time): Why does time have a direction? Why did the universe have such low entropy in the past, and time correlates with the universal (but not local) increase in entropy, from the past and to the future, according to the second law of thermodynamics? Is this phenomenon justified by the Gibbs law and the irreversible process?
With respect to all the answers, in my opinion, no answer to such questions is completely correct.
