Application of Image Denoising Method Based on Two-Way Coupling Diffusion Equation in Public Security Forensics

This paper uses the web live broadcast and on-demand platform based on the B/S architecture as the application side and designs a video image forensic system that can meet multiple police types and multiple application scenarios. The system uses mobile phones as the video image capture terminal to solve the problem of rapid response and concealment and uses 5G communication technology as the transmission medium to solve the problem of device mobility and link maintenance. The problem of diversification of the use and application modes of multiple police types is solved; the video image evidence is managed in a centralized storage, audit, and export method, and the security and authenticity of the evidence are solved. While the system realizes a series of functions such as the collection, transmission, storage, and application of video image evidence, it also realizes the application-side video image live broadcast function according to actual work needs and solves the large-scale case command and decision-making problem that has been plagued by public security organs. In order to remove the noise in the public security forensic images and to smooth the noise while retaining the details of the image, this paper proposes a denoising algorithm based on the two-way coupling diffusion equation. By improving the second-order partial differential equation, a new diffusion function with better diffusion effect than the original model is constructed. We combined the adaptive edge threshold and stop criterion to establish a new denoising algorithm model, which can get better denoising results. When the noise level is low, the PSNR value and SSIM value of several denoising methods are relatively ideal, and the result is at a higher level, the denoising picture effect is better, and there is no obvious incomplete noise removal or detail problems. As the noise level increases, the denoising results will gradually decrease, and the effects will also vary to different degrees. When the noise intensity increases, visually, it can be clearly seen that the two-way coupled diffusion equation and DnCNN have better denoising effects. When the noise level is high, the two-way coupled diffusion equation network is used to use the clear image and the denoised image for indistinguishable calculation. The method in this paper almost retains all the texture details in the clear image, and there are almost no artifacts and images. On the other hand, the color of the image after denoising by the method in this paper is more vivid, and it is closer to the target picture in terms of picture definition and tone, the denoising effect is ideal, and the generated image has a higher degree of restoration. Compared with the residual GAN, the two-way coupling diffusion equation network converges faster and the network performance is improved.

Architectural Style as a Symbol of Hudprom: The History of Battles of a Hundred Years Ago

The article deals with the problems of finding a national style in architecture in the early twentieth century. The issues of the main polemical aspects of the choice of artistic language as an expression of the artistic direction of the institution, the influence of the stylistic decision on the symbolism of the content of the institution are considered. The events that preceded the construction: competitions, discussions, confrontations of political opponents formed a very relevant discussion in search of an authentic form that would express the Ukrainian spirit. This is what created a clear image of the building, which is an association and a business card with Hudprom.

An Evaluation of English Department Coursebooks at Komar University: A Case Study

This research aims to give a clear image of coursebook evaluation in the English department of Komar University of Science and Technology (KUST) in Iraqi Kurdistan. The focus of this paper is to show the advantages and disadvantages of six coursebooks that are used in the English department of KUST. For this purpose, the researchers conducted interviews with the instructors and a survey with the students of these courses. These interviews and the survey show the good sides and the shortcomings of the studied coursebooks by asking different types of questions related to the contents of the books. The research took place in Fall-Winter 2019. The study results show that two-thirds of the teachers were satisfied with the coursebooks chosen to teach in the department of English to a large degree, and most of the students were satisfied with their coursebooks.

GAYA BAHASA KIASAN DALAM DONGENG ANAK BERBAHASA INGGRIS (STUDI KASUS KARYA BROTHERS GRIMM)

The purpose of this study is to investigate the use of figurative language in English children's fairy tales by Brothers Grimm with titled Hansel and Gretel, Rapunzel, and Snowdrop. This study specifically addresses the style of figurative language contained in English children's fairy tales. Style of figurative language are examined in this study includes metaphor, personification, simile, and hyperbole, in terms of form, meaning, function, and particularities in English children's fairy tales. Advanced Research is a qualitative research produces descriptive data in the form of the written word. This study did not use statistical data in the form of numbers, but rather to describe the form, meaning, types, functions, and uniqueness of figurative language in English children's fairy tales. The results showed that in the style of figurative language metaphor based on Haley’s hierarchy in nine metaphors, the metaphors in the three fairy tales are being, cosmos, energy, terrestrial, object, animate, and human. Personification in this research are inanimate personification and non-human personification. Simile in this research includes abstract (being), objects, cosmos, terrestrial, plants, and animals. Hyperbole in this research is hyperbole that state a thing and hyperbole that state a situation. Function of figurative language in the fourth type of style are; reveal the beauty in the style of figurative language, declare an abstract in a concrete way to give a clear image, stating things that are not captured by human senses, and cause freshness or emphasis the words, to give emphasis to a statement or situation, to intensify and enhance the impression and impact of the intent to deliberately overstate the thing and circumstances. Uniqueness found in the using of vehicle from the figurative language in the form of terrestrial, cosmos, and animal. Through this study it can be concluded that children in Europe, the reader or the audience of this tale, is expected to know the figurative language style.

Highly Efficient Lossless Coding for High Dynamic Range Red, Clear, Clear, Clear Image Sensors

In this paper we present a highly efficient coding procedure, specially designed and dedicated to operate with high dynamic range (HDR) RCCC (red, clear, clear, clear) image sensors used mainly in advanced driver-assistance systems (ADAS) and autonomous driving systems (ADS). The coding procedure can be used for a lossless reduction of data volume under developing and testing of video processing algorithms, e.g., in software in-the-loop (SiL) or hardware in-the-loop (HiL) conditions. Therefore, it was designed to achieve both: the state-of-the-art compression ratios and real-time compression feasibility. In tests we utilized FFV1 lossless codec and proved efficiency of up to 81 fps (frames per second) for compression and 87 fps for decompression performed on a single Intel i7 CPU.

COVERAGE OF INTERMOLECULAR FORCES IN ORGANIC CHEMISTRY TEXTBOOKS

The paper analyzes fifteen organic chemistry textbooks commonly used in Brazilian universities to examine intermolecular forces’ coverage in them. The findings revealed that the intermolecular forces are spread over a few pages (less than 1%) in a fragmented way, and over several chapters that do not provide enough information to help create a clear image in the student’s mind. Thirteen textbooks contained end-of-chapter problems related to intermolecular forces. However, less than 1.3% of the total (212) are associated with intermolecular forces. This deficient approach to intermolecular forces in Organic textbooks can lead to teachers’ lack of interest in teaching the subject, leading to students failing to learn this important organic chemistry topic

Ancient Biographies of Statesmen

This chapter discusses ancient biographies of statesmen. What is the nature of ancient political biography? It is the description of the life and deeds of a significant political player of the recent or far past, individually told or in a series, with the intent of edifying the readers. This means that such a work often has an encomiastic, or at any rate evaluative cast, and may even employ certain acknowledged untruths in order to bring out the characteristic significance of a given politician. This too is the aim with which intimate details or gossip are told: so as to convey a clear image of what kind of man Solon, Demosthenes, Augustus, or Nero was, and how this influenced his career and his deeds.
