The goal of the research is to show how artificial intelligence may be used to identify driver tiredness using visual processing. Experts estimate that over a quarter of all serious car accidents are brought on by drivers who are too sleepy to pay attention to the road. As a result, we know that tiredness is a more common contributor to car accidents than intoxication. Vision-based ideas were used to design the Drowsiness Detection System. The gadget relies on a small camera to detect drowsiness in drivers by examining their eyes and scanning their face. The Viola-Jones and Hough transform are the techniques utilised by the system to first scan the driver's face, then the eyes, and then check whether the eyes are open or closed using artificial intelligence software. The system works with binary pictures to scan the sides of the face, reducing the space where the eyes will be located. Let's say that the eyes are shown to be closed for five or more consecutive frames. When this occurs, the system tracks the driver's level of activity and determines that the driver is dozing off, so it sounds an alert or produces an alarm signal to wake him up.

A wireless sensor network consists of numerous sensor nodes which are capable of entering and departing from the network according to their wish. The implementation of sensor networks is done at far places and they are small-sized. Thus, energy consumption becomes the main issue of WSN. Due to the limited energy of sensor nodes, the data that is collected from the intended environment is sent directly to the main station. The sink node receives the data that several sensor nodes send. The decision-making process is implemented by identifying and removing similarities between the data from various sensor nodes. In addition, the sink makes the deployment of obtained data locally as well as transmits these data to the networks which are executed far away. The existing research work employs CTNR, an energy-efficient protocol that is capable of enhancing the duration of WSN. The CTNR protocol consists of two-level hierarchies for mitigating the energy utilized in WSN. This protocol assists in choosing the CHs (cluster heads) on the basis of distance and energy. This work will focus on enhancing the CTNR routing algorithm so that the life span of the network can be prolonged.

Induction motors are most commonly used in many industries, including petrochemicals, oil, and steel. A single failure in any of the induction motor's components or sub-components can result in a plant shutdown. The plant will suffer significant financial losses as a result. It is crucial to diagnose different types of faults in induction motors. Various condition monitoring techniques diagnose faults in induction motors in the early stages. Vibration analysis is most commonly used among different condition monitoring techniques due to its higher accuracy than other methods. Vibration analysis is used to detect various types of faults in induction motors. The acceleration vibration data corresponding to multiple types of defects are gathered from publicly available web resources. The primary objective of this research work is to explore the severity of horizontal and vertical misalignment defects utilizing a signal processing approach. To achieve this objective, Discrete Wavelet Transform (DWT) is used to detect abnormal behavior of the induction motor. The Daubechies-4(db4) wavelet is chosen as a mother wavelet. As Daubechies wavelet is an orthogonal wavelet, the percentage energy in all decomposed sub-band will equal the original energy of the signal. The energy level of sub-bands is compared with the healthy condition of the motor to detect significant changes in motor fault.

Deep learning and neural networks have become increasingly popular in the area of artificial intelligence. These models have the capability to solve complex problems, such as image recognition or language processing. However, the memory utilization and power consumption of these networks can be very large for many applications. This has led to research into techniques to compress the size of these models while retaining accuracy and performance. One of the compression techniques is the deep compression three-stage pipeline, including pruning, trained quantization, and Huffman coding. In this paper, we apply the principles of deep compression to multiple complex networks in order to compare the effectiveness of deep compression in terms of compression ratio and the quality of the compressed network. While the deep compression pipeline is effectively working for CNN and RNN models to reduce the network size with small performance degradation, it is not properly working for more complicated networks such as GAN. In our GAN experiments, performance degradation is too much from the compression. For complex neural networks, careful analysis should be done for discovering which parameters allow a GAN to be compressed without loss in output quality.
‘Hope it’s useful’: Negotiating first and second order accounts in discourse-based interviews

Published: July 2023

Framework: Although participatory approaches highlight the expertise of the participants and assign them responsibilities over the research process, there is less systematic discussion about the participants’ actual involvement in practice especially in the analysis and interpretation of the data. Despite the claims of equal partnership, the participant is often still perceived as the subject revealing hidden yet simple inside knowledge (first order account) around which the researcher, as a neutral outsider, builds complex theories by drawing on his/her scientific expertise (second order account). Goal and method: Our goal is to investigate how first and second order accounts contribute to a multi-layered analysis of the interview encounter by challenging binary thinking. We also explore the way interactional sociolinguistic methodology can inform participatory research by analyzing the way first and second order accounts are negotiated between interviewer and participant. We present the analysis of a discourse-based interview extract from our ongoing and completed work on the discourse analysis of formality in workplace emails in multinational companies in Greece. Findings: The results illustrate iterative processes of negotiation of meaning in situ and in line with the participants’ temporary and social roles. They highlight the importance of collaborative framing of the interpretation of and theorization from data in which the participants are co-creators. Shifting from static and purely essentialistic or constructivist understandings of the interviewer and participant to a holistic approach, this paper frames the interview encounter as an interactional domain of activity that can better capture the complexity of the lived experience.

Duralumin alloy is widely used in the aircraft industry, in the production of high-speed trains (for example, Shinkansen trains) and in many other branches of mechanical engineering (since it is significantly more durable than pure aluminum). Along with high operational properties, the diverse use of duralumin is due to its high technological efficiency, which creates prerequisites for obtaining products by all known methods of casting and plastic processing. Duralumin belongs to the category of structural alloys, which are characterized by increased strength. They are based on aluminum. Copper, manganese, and magnesium are used as additives in different percentages. The properties of duralumin depend on the heat treatment and the amount of alloying elements added. The article presents the results of a study of the effect of calcium on the anodic behavior of aluminum alloy АlМg5.5Li2.1Zr0.15 of the duralumin type in the medium of the NaCl electrolyte. The study of the corrosion−electrochemical behavior of alloys was carried out by a potentiostatic method in a potentiodynamic mode with a potential sweep rate of 2 mV ⋅ s ^(-1). It is shown that calcium additives reduce the rate of anodic corrosion of the initial alloy АlМg5.5Li2.1Zr0.15 by 8-10%. It was found that an increase in the concentration of chloride ions contributes to an increase in the rate of anodic corrosion regardless of the calcium content in the alloy АlМg5.5Li2.1Zr0.15.

Authors: Razimi Husin Mohd , Din Nasirudin Zakariah , Azman Nor Azwin
Published: July 2023

This study aims to build a basic TPR Model of Al-Quran Recitation based on the PiTaH Al-Quran Recitation Model. A previous study found that learning methods that are less effective in secondary schools caused 60% of the 320 students who were studied to be blind to the Qur'an. While 9.5% of primary school students are still at a weak level even though the main goal of this program is to achieve that all students can complete the Qur'an with the teacher. Therefore, the learning process needs to be improved to improve the level of student achievement. This needs to be overcome with effective learning methods to ensure that learning objectives are fully achieved. Previous studies have also produced a teaching and learning model of recitation of the Quran that takes into account the diversity of student backgrounds in terms of race, language, culture, age, socio-economics and level of education. This study uses the literature review method by obtaining information based on the findings of previous studies to build an up-to-date model that is guided by the PiTaH Model. Thus, the researcher will build an effective teacher's pedagogy module through physical movement activities (TPR) to help overcome the problem of teaching load in the classroom. This study involves the construction phase of a model based on the teaching and learning model of recitation of the Quran. This study is expected to help researchers build the Total Physical Response (TPR) module for AlQuran Recitation.

We present the case of a 44 year-old Caucasian male (V.B) with a known psychiatric history of paranoid schizophrenia, admitted to “Prof. Dr. Al. Obregia” Clinical Hospital of Psychiatry during the months of May-July 2015 (67 days of hospitalization) for: compound and complex auditory and visual hallucinations, paranoid delusions, hallucinatory behavior, psychotic anxiety and sleep disturbances, symptoms which had intensified in the several months preceding admission despite following adequate antipsychotic treatment. We present the difficulties we encountered in treating his resistant psychosis, the process of diagnosing his co-morbidities (beta-thalassemia and latent Toxoplasma gondii infection), a differential diagnosis of the intense positive symptoms the patient presented and the implications of toxoplasmosis in the evolution and treatment of a paranoid schizophrenic patient. Conclusion. The scope of this paper was to show the importance of performing a differential diagnosis and a thorough workup however certain we are of the patient's initial presentation. We also wanted to emphasize the need for studies that present more effective treatments of resistant psychosis with fewer adverse reactions. The etiology of schizophrenia presents a tremendous challenge for both researchers and physicians, the latent toxoplasmosis infection observed in high prevalence among schizophrenic patients representing only a small part of what remains to be discovered. Ultimately we must draw attention to the importance of a multidisciplinary approach to every case encountered.

The Painting of Fernando Botero: Universality and National Identity
Authors: Sheleshneva-Solodovnikova N. A.
Published: July 2023

The outstanding contemporary artist Fernando Botero Angulo (b. 1932) is one of the leading artists of the postmodern era, thanks to the paraphrasing and irony of his works. He is also known as a graphic artist and a sculptor. Botero’s graphic and pictorial works are kept in many museums around the world, including the Russian ones — the State Hermitage Museum in St. Petersburg and the Pushkin State Museum of Fine Arts in Moscow; his sculptures adorn the cities of Europe, America, Asia. This article focuses on the artist’s painting: it gives an idea of him as a master who reflected universality and at the same time national identity of his country through landscape, still life, bullfighting, dancing. Several parts of the article are devoted to: «Biography and “circular form”», «Secular and religious images», «Landscape, interior, still life», «Bullfighting, music, dancing». A significant place is given to the «circular form», since it made the artist a unique creator, who used it in many great works of art, and then created images recognizable by everyone who has ever seen Botero’s paintings. There are various genres of the master’s works, in which he acts not only as a creator of a unique form, but also as a brilliant colorist. Botero managed to raise Latin America to a high pedestal; starting from the pan-European tradition, he showed the universal through his native Colombia.

The Pongkor Gold mine is under Production Operation Permit until 2031 while existing feasibility study stated that Pongkor gold Mine only have economical number until 2025 with ore volume in 1.5 million wmt and ore grades above 4 gpt. Pongkor Gold Mine has resources in low-grade gold ore (below 4 gpt) in 1.9 million wmt with the grades is 3.61 gpt. Having a gap period between mining permits (until 2031) and the latest feasibility study (until 2025) and abundant resources in low-grade gold ore, provides research opportunities to finding how to formulate business strategy level for Pongkor Gold Mine in order to maximize gap period by processing low-grade gold ore. This study started with business situation analysis, with VRIO and Internal Factor Evaluation (IFE) Matrix are conducted for internal analysis, while PESTLE (Political, Economic, Sociocultural, Technological, Legal, and Ecological) analysis, Porter’s Five Forces framework and External Factor Evaluation (EFE) matrix are conducted as external environment analysis. The result shown Pongkor Gold Mine in region V in internal-external (IE) matrix, the region indicated that hold and maintain strategies are suitable for Pongkor Gold Mine. Study continued with Porter generic competitive framework to define the strategy that most suitable with Pongkor Gold Mine condition. The result shown cost leadership strategy is the most suitable strategy with the detailed strategy are (i) implement a cost reduction program every year, (ii) substitute retired organic workers (permanent Employee) with outsourced or contracted workers, (iii) limiting investment only to things that have a direct impact on revenue and (iv) long-term contract in heavy equipment. The impact of these strategies will calculate in financial feasibility study. Financial feasibility study uses financial criteria of Net Present Value (NPV), Internal rate of return (IRR), and payback period (PBP). The results shown NPV in 25.33 million US$, IRR in 52.2% and payback period in 21 months, these number indicated the Pongkor project extension is feasible. This study also intended to determine the most affecting variable to the NPV by conducting sensitivity analysis. The results shown the extension project is feasible as long as the gold price not declined more than 18.4% from the base, production cost (COGS) not increased more than 22% and the productivity not decreased more than 16.94% from the base.

Published: July 2023

The active group (s) content of Curcuma longa rhizomes (CLR) makes it a medicinal plant with a reasonable therapeutic potential. Therefore, in this study, we attempted to clarify these groups using standard preliminary phytochemical screening tests. Results revealed detection of Alkaloids, Glycosides, Carbohydrates, Cardiac Glycoside(s), Saponin, Gallo-tannins, or Catecho-Tannins (hydrolysable or condensed), respectively, Flavonoids, Resins, Steroids, Fixed oils, and Protein compounds. Anthraquinones, Gums or Mucilage and Terpenoids were not noticeable. Phlobatannins content is suspect. These findings may prove CLR is a rich source of active groups, suggesting that it may be a nutraceutical-based medicine in the pharmaceutical and cosmetic industries.

In the orthophoto processing one of the key steps is the aerial triangulation during which the exterior orientation coefficients of the photographs are determined by adjustment. In order to be able to do this with sufficient accuracy, in addition to knowing the internal orientation elements of the cameras, we need the eccentricity vectors of the GNSS antennas, IMU and sensors determined in relation to each other, i.e. the lever arms. Characteristic points of the airplane and the installed instruments are measured using 3D polar method, while vectors are traditionally determined using a geometric technique. In this paper we will present an algorithm which uses an analytical geometric approach for much quicker and more precise results.
