Authors: Qodirov Umut
Published: April 2023

Maqaolada kulturologik yondashuv asosida chet tili (ingliz tili)ni o‘qitishdagi afzalliklar bayon etilgan. Chet tilini o‘qitishda madaniy komponentlarni jalb etish va o‘rganilayotgan tilda muloqot qilish qobiliyatini shakllantirish - bu amaliy maqsadga erishish uchun mutlaqo zarur hisoblanadi. Shunday qilib, chet tilida so‘zning haqiqiy ma’nosini anglagan holda muloqot qilishni o‘rganish ijtimoiy-madaniy bilim va ko‘nikmalarni yetarli darajada egallashni talab etadi. Kulturologik yondashuv beshta vazifani amalga oshiradi: rivojlantiruvchi, ta’limiy, tarbiyaviy, kognitiv va kasbiy. Chet tilini kulturologik yondashuv doirasida o‘qitish o‘qituvchi va o‘quvchilarning birgalikdagi faoliyati bilan amalga oshadi, bunda birinchi navbatda, bilim, ko‘nikma va malakani tinglovchilarda shakllantirish, ikkinchisi esa bu bilim, ko‘nikma va malakalarni o‘zlashtirish va tatbiq etish; ijtimoiy jarayon sifatida esa ijtimoiy-iqtisodiy tajribani o‘zlashtirish va  jamiyat taraqqiyotining ehtiyojlari bilan belgilanadi. Shu bilan birga, O‘zbekiston ilmiy adabiyotlarida universitet talabalariga virtual darslarda ingliz tilini o‘rgatishning zamonaviy muhiti va sharoitida kulturologik yondashuvni qo‘llash muammolariga bag‘ishlangan keng qamrovli tadqiqotlar mavjud emas, bu bizning ishimizning dolzarbligini ko‘rsatadi.

Sinfda o‘qitishning teskari modeli o‘quvchilarning odatdagi sinfdan tashqari faoliyati (masalan, muammoni hal qilish amaliyoti) sinfda olib boriladigan model sifatida tavsiflanadi. Sinfdagi mashg’ulot odatda sinfda qanday amalga oshirilishidan farqli o‘laroq (masalan, tushuntirish, ma’lumot uzatishni o‘rgatish) darsdan tashqarida va dars boshlanishidan oldin yakunlanadi. “Teskari modul” atamasi sinfni yon tomoniga aylantirishni o‘z ichiga olgan o‘qitish usulini anglatadi. “Teskari modulning” ko‘plab afzalliklaridan biri shundaki, u o‘qituvchilarga talabalar bilan bevosita ishlashga ko‘roq vaqt sarflash imkonini beradi. Talabalarni samarali baholash uchun sinfda viktorinalar yoki testlardan foydalanish talabalarning bevosita muloqotiga sarflangan vaqtni non- interaktiv baholashni   foydasini kamaytiradi.

Published: April 2023

O envelhecimento da pele é um processo natural, causado tanto por fatores intrínsecos ou genéticos, como por fatores extrínsecos. Mundialmente, a demanda por produtos que previnam o aparecimento das características de envelhecimento da pele, tem aumentado acentuadamente. Contudo, é fundamental entender a etiologia do envelhecimento para o desenvolvimento de tratamentos cada vez mais personalizados. O objetivo dessa revisão é discutir como o conhecimento sobre o envelhecimento biológico, os polimorfismos genéticos e as vias metabólicas celulares, podem contribuir na formulação de cosméticos personalizados com ação antienvelhecimento. Estudos em diferentes populações mundiais estão procurando associar polimorfismos de nucleotídeo único (SNPs) com envelhecimento. Pesquisas de SNPs usando a ferramenta de Genome-Wide Association Study (GWAS) mostram resultados heterogêneos, o que dificulta a validação desses biomarcadores. Para superar essas dificuldades, estudos recentes usando a ferramenta Gene Set Enrichment Analysis (GSEA) têm tentado associar modelos biológicos com parâmetros de envelhecimento, o que pode fornecer um conhecimento biológico mais integrado e abrangente. Apesar dos esforços, os marcadores moleculares, com foco dermatológico, ainda não foram validados, sendo necessários estudos em larga escala. Contudo, essas tentativas de avaliação abrangentes dos aspectos genéticos relacionados ao envelhecimento cutâneo em diferentes populações estão permitindo que o setor de cosméticos esteja cada vez mais próximo da ciência, o que beneficia tanto os consumidores quanto as empresas do setor.

Augmented reality helps us to visualize computer-generated content in our physical space. Often, when you buy furniture or any other decorative item, you regret that purchase as it did not suit your home space. The inability to place that object in your home space before buying it, probably due to the size of the furniture or some other reasons renders this problem. Augmented reality can help to solve this problem. Using AR one can view 3d models of furniture in their home or office environments and purchase them accordingly. This can help businesses to reduce the return rate, and increase order and cart conversion rates of the products thereby improving customer experience and benefiting the retailers

Currently, the record keeping of the clients and projects is maintained manually via excel sheets which is a time consuming and cumbersome activity. The current process involves taking the project requirement through emails, updating the excel sheet as and when any new request comes, evaluating the project based on the criteria and so on. Hence it is felt to develop a portal to standardize the project initiation/evaluation. This in turn would help in providing a centralized view of the projects, enabling ready reference to the status and details of the project. To curb this problem there should be a solution feasible and accessible to each person. Managing clients, projects, meetings etc. in a fast and easy way makes the future and management of clients an easier task at hand. Owing to the current trend of using excel sheets for recording clients’ credentials, a tool that helps as well as promotes sales and engage clients, managing their details would be benefiting

Published: April 2023

In recent years, cloud computing has become a popular way of storing and sharing data. However, security concerns have been raised about the safety of sensitive information stored on the cloud. Hybrid cryptography, which combines symmetric and asymmetric encryption, has been proposed as a solution to these concerns. This paper proposes a new hybrid cryptography approach for secure file storage on the cloud regardless of the type of deployment model i.e., either public cloud, private cloud, or hybrid cloud. The proposed approach uses a combination of the Advanced Encryption Standard (AES) algorithm, Triple Data Encryption Standard (DES) algorithm, and Rivest cipher 6 (RC6) algorithms are used to provide block-wise security to data. LSB steganography technique is introduced for key information security.

Paper present the project designed to correcting power factor for domestic, Commercial, Industrial. Which with hope to make the cost and energy usage efficient, because the energy source is depleting due to increase in population. Power factor is the ratio of real power and apparent power. This definition is mathematically represented as kW/kVA where kW is active power and kVA is apparent power (active + reactive). Reactive power is the non-working power generated by the magnetic and inductive load to generate magnetic flux. The increase in reactive power increase the apparent power so the power factor will decrease. Low pF will cause the industry to meet high demand thus making it less efficient. The main aim of this project is to increasing the current power factor of industries from 0.85 to 0.90. Power factor compensation contribute to reduction in current-dependent losses and increase energy efficiency while expanding the reliability of planning for future energy network. As technology develops, the gradual cost and efficiency penalty should reduce. Therefore, automatic power factor compensation device should become cost-effective and smaller device over time. That is the reason this project is using programmable device as it is a miniature architecture device.
Fellini Lexicon
Authors: Rohdie Sam
Published: April 2023

Federico Fellini (1920-93) was one of the most inventive of film-makers and he remains one of the best loved. Director of a whole series of celebrated films - among them La Strada (1954) The Nights of Cabiria (1957), La Dolce Vita (1960), Otto e Mezzo (1963) and Amarcord (1973) - he created melancholy, magical worlds peopled by clowns, dreamers, conmen, trumpeters and werewolves. Fellini Lexicon explores the forms and substances, significances and insignificances, objects and shadows in Fellini’s work - the dance and music of his characters, the colour, light, and movement in his images. The Lexicon accompanies Fellini’s films, rather than seeking to possess them, taking pleasure in their incongruities, exaggerations, absurdities and surprises. The entries are reversible, overlapping, often unlikely, combining careful analysis of the films with a celebration of their richness. Fellini Lexicon is an original, delightful approach to Fellini’s work and to the practice of film criticism.
A new bluish-leaved Syagrus (Arecaceae) from an overlooked OCBIL in the Espinhaço Range (Brazil)
Authors: Sant'Anna-Santos Bruno Francisco , Micheli Rafael , Carvalho Luiz Fernando Lima , Soffiatti Patrícia
Published: April 2023

Background and aims – This study is part of ongoing research on the Arecaceae Flora of the Serra do Cabral, an isolated massif in the southwest of the Espinhaço Range in Minas Gerais State. Because of the isolation of the massif, the area has a rich biodiversity and a high level of endemism. While searching for populations of the rare and critically endangered Syagrus cabraliensis, a new bluish-leaved palm species was discovered and it is described here.

Material and methods – The new species’ morphology is described based on field collections. The pinnae were analysed using SEM and LM cross- and longitudinal sections following default methodology. In addition, we compared the species to S. cabraliensis and provided ecological notes and a conservation status assessment.

Key results – Syagrus carvalhoi resembles S. cabraliensis but they can easily be distinguished by morphoanatomical characters. Both species occur non-sympatrically in the Serra do Cabral, in contrasting microhabitats: S. carvalhoi in the southern quartzitic campos rupestres and S. cabraliensis in the northern ferruginous campos rupestres. A key to the known grass-like Syagrus species from the massif is provided. Based on the restricted area of occurrence and the anthropogenic threats, Syagrus carvalhoi is assessed as critically endangered.

Conclusion – Syagrus carvalhoi is the second grass-like endemic Syagrus species from the Serra do Cabral and presents rare characters within the genus (grass-like aspect, colonial habit, flowers in tetrads, and the stem forking at or below the ground). This discovery corroborates that this isolated OCBIL is a home for endemic and rare palm species. The Serra do Cabral massif has proved a source of morphological and anatomical novelties in Arecaceae, affecting the taxonomy and understanding of the evolution and ecology of palms. Our results reinforce the notion that it is important to conserve this area with rich and rare biodiversity but under alarming and unprecedented threats.

Authors: Niedobylski Sylwiusz , Wachoł Konrad , Moqbil Sara , Smoleń Agata , Lewicki Marcin
Published: April 2023

Introduction

The prediction of how an infection of a new pathogen, such as SARS-CoV-2, will evolve using traditional modelling methods can turn out unattainable, although it could be achievable using in silico techniques. The purpose of this study was to create an artificial neural network that estimates the risk of SARS-CoV-2 infection in individuals after physical contact with confirmed COVID-19 cases.

Material and methods

A cross-sectional study was conducted with the original 118-item questionnaire. Information concerning participants’ demographic, the circumstances of the contact with an infected person, general medical history, lifestyle, preventive behaviours, and the result of COVID-19 test after the contact, was obtained. The study included 1050 participants. The data were used to train and validate an artificial neural network. The project was funded by the Ministry of Education and Science as part of the „Studenckie Koła Naukowe Tworzą Innowacje” student competition (project no SKN/SP/496779/2021).

Results

The model in the analysis of total available cases had an area under Receiver Operating Characteristic curve (AUROC) of 0.87, a sensitivity of 87.2%, specificity of 80.6% and prediction accuracy of 84.5%. The model shows a high capacity for generalisation - in the testing data set: AUROC 0.76, sensitivity 86.2%, specificity 68.3%, prediction accuracy 78.7%.

Conclusions

The developed tool is capable of high quality generalisation of the collected data, which translates into its ability to assess the risk of SARS-CoV-2 infection in a person after contact with a COVID-19 case. It has been deployed as an online calculator available on: https://www.umlub.pl/uczelnia/struktura-organizacyjna/szczegoly,317.html
Hybrid Lossless Compression Techniques for English Text
Authors: Jannat Tariq  , Mahmood F. Mosleh  , Maha Abdulameer  , Huthaifa A. Obeidat  , Omar A. Obeidat
Published: April 2023

Since the demand for data transfer and storage is always increasing, sending data in its original form will take a long time to send and receive. Compression is an important issue for digital communications systems because it imposes an important rule while reducing complexity and power requirements. The goal of compression is to reduce the file size without compromising the quality of the information, which leads to more capacity saving and reduces the required bandwidth in terms of the communications system. This paper proposes a system that consists of a hybrid of two lossless techniques, including a concatenation of Huffman and LZ4 in order to enhance the traditional techniques. The result of the proposed system demonstrates that the proposed combination techniques reduce the file size significantly, achieving between 73.649 % and 79.708 % in terms of average saving ratio (SR). The above would give us credible, cost-effective, and affordable lossless encoding systems for electronic communication systems.

Published: April 2023

This study is conducted to assess the water quality index (WQI) of the Diyala and Tigris River confluence region south of Baghdad (Al-Tuwaitha), based on the Weighted Arithmetic method. Sixteen samples of water were collected from different location in the region through two periods 5/11/2021 and 13/3/2022. Water quality parameters such as (PH, EC, TDS, TH, Ca, Mg, Cl, Turbidity, ALK, SO4, HCO3, Na, and K) were used to evaluate WQI in the study area.
The final results showed that the water was not suitable for drinking due to the high concentration of water quality parameters. In the 5 November 2021, the water quality in the study area was classified into (good, poor, very poor, and polluted) where the percentages of the above classes were 4%, 6%, 39%, and 51% respectively, while the percentages for the season 13thMarch 2022 were 1%, 41%, and 58% with very poor, polluted, and very polluted class, respectively.
The water was not suitable for drinking due to the high concentration of water quality parameters in most locations in the study area.  There are many sources of pollution in the region that dump their harmful waste into the river, which led to increase the concentrations of water quality parameters in most locations of study area.

Published: April 2023

The current study examined how the annealing process affected the formability, mechanical and chemical characteristics of 7075 alloy. The formability was achieved during the bending test. Tensile, hardness, microstructure and corrosion tests represent mechanical and chemical properties. The test specimens for each test were prepared then followed by annealing heat treatment by heating them to 200 and 300°C in an electrical furnace for two hours. Then, the specimens were allowed to cool in the furnace to a room temperature. The results indicate that the tensile strength and hardness were decreased for about 50%. Bending strength was increased by approximately 30%, where the specimens bent at a very high angle without cracking or breaking in comparison to base metal.

Published: April 2023

Facial palsy (FP) is a disorder that affects the seventh facial nerve, which makes the patient unable to control facial movements and expressions with other vital activities. It affects one side of the face, and it is usually diagnosed by the asymmetry of the two sides of the face through visual inspection by a doctor. However, the visual inspection is human-based, which is prone to errors because the doctor is exposed to omission due to fatigue and work stress. Therefore, it is important to develop a new method for detecting FP through artificial intelligence and use a more accurate computerized system to reduce the effort and cost of patients and increase the accuracy of diagnosis. This work  aims to establish a safe, useful and high-accuracy diagnostic system for FP that can be used by the patient and proposes to detect FP using a digital camera and deep learning techniques automatically. The system could be used by the patient himself at home without needing to visit the hospital. The proposed system trained 570 images, including 200 images of FP palsy. The proposed FP system achieved an accuracy of 98%. This confirms the effectiveness of the proposed system and makes it an efficient medical examination tool for detecting FP.

Published: April 2023

Although the scheduling of maintenance tasks for generators is not a new issue, it has recently attracted new attention due to the significant rise in demand for expanding power system size in modern power systems. Generator Maintenance Scheduling (GMS) is a nonlinear optimization problem, highly dimensional and constrained, and determines when power-producing units must undertake well-planned preventative maintenance. The objective function includes binary variables to indicate whether a generator is undergoing maintenance at a given time and is subject to several restrictions described in this paper.  However, the biggest concern of GMS is to produce a precise timetable for preventive maintenance of generating units with low cost and high reliability. Despite that, regrettably, a large volume of research works has accomplished solutions towards a model of GMS with the consideration of either maximizing system reliability or minimizing operation costs as an objective of their research work. This is called Single-Objective Problem (SOP), which involves one objective function that needs to be optimized. SOP is solved by Single-Objective Optimization Method (SOOM). The primary purpose of the research is to present a review of SOOM methods used in solving GMS problems.

The safety of children is one of the fundamental concerns of parents. Recently, child kidnapping has increased by a large percentage, some children have been found, and some children have not found yet. This paper proposes an indoor localization system based on ZigBee wireless sensor network (WSN) and Backpropagation Artificial Neural Network (BP-ANN) to locate the child in an indoor environment. Several ANN topologies were investigated to select the best one with minimum tracking or localization error. The Received Signal Strength Indicator (RSSI) was collected from four ZigBee XBee S2C anchor nodes by the mobile node carried by the child in an indoor area of 32m × 32m. The RSSI was collected from 127 test points inside the tested area. The measured RSSI was used to train, test, and validate the performance of BP-ANN to determine the two dimensions (2D) of the target child’s location. Different topologies of ANN have been examined for training, testing, and validation which are 5-5, 10-10, 15-15, and 20-20 neurons in the hidden layer. The findings indicate that the 20-20 ANN topology can achieve higher accuracy than other topologies. Additionally, 20-20 topology localization errors were 1.0, 1.157, and 1.356 m for training, testing, and validating ANN performance.

In the age of the Internet, a lot of images are circulated among users, and some of these images contain financial or personal information that requires confidentiality. Encryption algorithms existed for a long time, and the data used was focused on the text data, while the multimedia data was neglected for a long time. In addition, there are significant shortcomings in 3D image coding techniques. This paper proposed a method for image encrypted and decrypted electronically using the Lorenz chaotic system, the supposed algorithm was developed by using the three equations of the Lorenz system, before that, the image pixels are destroyed using reversible shifting and rotating processes to increase the randomness of the encrypted pixels and thus the difficulty of cracking the cipher. Then he supposed technique gave the following results: The average entropy calculation was (7.285) before image encryption and (7.9974) after image encryption with an average NPCR of (99.65%) and UACI was (30.35%) this confirms that the proposed method is reliable and applicable. Moreover, the suggested technique gives the best outcomes when compared to other similar works.

Published: April 2023

The tongue reflects the abnormal condition and behavior of the internal organs of the body, such as problems of the heart, liver, pancreas, stomach, intestines, blood diseases and others, which lead to changes in some of the features and characteristics of the tongue. The most important of these is tongue color, which can be adopted as a biometric that can be used in Computerized Tongue Diagnostic Systems (CTDS). Quantitative diagnosis of the tongue requires some devices, including image acquisition devices such as cameras, light sources, filters, color checkers, image analysis and processing devices through the application of some algorithms or image processing and color correction software, as well as a computer. This study proposes a real-time imaging system to analyze tongue color and diagnose diseases using a webcam under specific conditions. The proposed system was designed in a Matlab GUI environment. After testing the system on a data set of more than 100 images, the preliminary results showed that the proposed system gives a disease diagnosis with an accuracy rate of no less than 86.667%. The proposed system contributed to the diagnosis of several diseases in real time, with an accuracy of 95.45%, with ease of use, implementation and low cost. This gives impetus to further studies to apply computerized diagnosis in medical applications, to enhance the medical reality, monitor patient health, and make an accurate diagnosis.

Published: April 2023

Urine color analysis is one of the most helpful indicators of health status, and any changes in urine color might be a symptom of serious disease, dehydration of the body, or caused by drugs. To get better assistance for urine color detection in the proposed system, a urine color automatic identification has been developed based on computer vision. The proposed system uses a web camera to capture an image in real-time, analyze it, and then classify the color of urine by using the random forest (RF) algorithm and show the result via the Graphical User Interface (GUI). In addition, the proposed system can send the results to the mobile phone of the patient or care provider by using an Arduino microcontroller and GSM module. Moreover, sending a voice message about the color of urine is related to pathological conditions. The results showed that the proposed system has high accuracy (approximately about 97%) in detecting urine color under different light conditions, with low cost, short time, and easy implementation. In the comparison with the current methods the proposed system has maximum accuracy and minimum error rate. This methodology can pave the way for an additional case study in medical applications, particularly in diagnosis, and patient health monitoring.
