The article provides information about modern problems of writing the Kazakh language, the importance of its role and development in the context of mass digitization using artificial intelligence technologies and computational linguistics methods. The incorrectness of the current alphabet of the Kazakh language based on the Cyrillic alphabet is proved in connection with the inclusion of Cyrillic letters in it, denoting phonemes that are not included in its sound structure. The necessity of reforming the Kazakh writing by replacing the incorrect... alphabet is substantiated. Errors and contradictions are shown in the approved version of the Kazakh alphabet based on the Latin alphabet, as well as the alphabet proposed as a replacement for the approved one, in which some previous errors are repeated. In both cases, no analysis and clarification of the sound system of the Kazakh language, which is the basis of any alphabet, is carried out. In this study, to clarify the sound system of the Kazakh language, experiments were carried out to determine the articulation and acoustic features of Kazakh sounds with the help the computer programs used for many natural languages. In the articulation analysis, special attention was paid to vowels, which give rise to various contradictions in the Kazakh letter. It is proposed to use a new classification of vowels according to four binary features, rather than the traditional classification according to three binary features. Acoustic analysis uses the method of formant analysis, which is aimed at identifying certain formants in the spectrogram. The formant is obtained using a spectrograph. Quantitatively, the formants correspond to the maxima in the speech spectrum and usually appear on spectrograms as horizontal bands. After determining the composition and classification of the sound system of the Kazakh language, two variants of the alphabet based on the Latin alphabet are proposed: the first one is based on the Turkish alphabet using diacritical marks; the second is based on the English alphabet using digraphs. The second option offers ways to solve problems that arise when using digraphs. In conclusion, information is provided on the ongoing and ongoing work in Kazakhstan related to the creation of smart systems in the Kazakh language based on the methods and technologies of artificial intelligence and computational linguistics, the results of which are reflected in the list of sources.Read more

This study evaluates the impact of precipitation on water quality in Heidelberg, Germany’s recreational lakes during sporadic rainfall events from August to September 2023. Data were collected from five stations, monitoring physicochemical properties and nutrient levels before and after rainfall. Measurements of dissolved oxygen, pH, conductivity, and redox potential were conducted in situ, while turbidity, nitrates, phosphates, sulphates, zinc, and copper levels were analyzed in the SRH Heidelberg water laboratory. Findings indicate pH l...evels increased due to dilution effects, while conductivity rose due to runoff, enhancing ion concentration in the lakes. Dissolved oxygen levels also increased, attributed to aeration from rainfall-induced surface turbulence. Redox potential decreased, reflecting atmospheric oxygen dissolution. Nutrient concentrations, including nitrates and phosphates, along with sulphates, declined post-rainfall, suggesting a dilution effect without significant impact from surface runoff. This outcome implies the absence of major nutrient and sulphate sources upstream. Heavy metals like zinc and copper also decreased in concentration, indicating no introduction through runoff or sediment transport. The study underscores the variability of water quality parameters across different lakes, influenced by factors such as water sources, surrounding land use, geological conditions, and lake characteristics. Overall, water quality improved post-rainfall, making the lakes suitable for recreational activities, with the study establishing a non-linear correlation among the water quality parameters and deducing the P ratio for each parameter.Read more

The objective of this research paper is to examine and assess the correlation between the economic expansion of European Union member states and the escalating rate of motorization, which subsequently leads to road accidents resulting in significant loss of life and injury. A statistical analysis of economic growth, the rate of motorization, and road incidents in EU member states from 2010 to 2020 constitutes the research methodology. The research paper employs a quantitative approach to analysis and comparison. The research paper demonstrates ...how an increase in the number of motor vehicles in EU member states contributes to road accidents and human mortality. Varying degrees of economic development are associated with disparities between the rate of motorization expansion and the decline in fatalities. Because the rate of increase in motor vehicle usage surpasses the decline in fatalities per motor vehicle at low-income levels. At increased levels of income, the opposite occurs. Practical Implications: This research paper illustrates the importance for road traffic safety authorities to be aware of safety performance indicators and to incorporate them into legislative deliberations in order to bolster the European Union’s “zero victims” objective and provide enhanced protection for motor vehicle accident victims. Originality – This paper examines the correlation between motorization rates and fatalities in various EU member states with varying degrees of economic development over the past few decades.Read more

Maize stem borer (Chilo Partellus), poses a substantial threat to maize crops all over the world, causing damage that ranges from 26.7% to 80.4%. Its destructive impact includes killing the shoot in young plants, leading to a “dead heart,” and damaging the upper stem in older plants through boring activity. To combat this issue, a field experiment evaluated various insect growth regulators (IGRs) such as Lufenuron®, Pyriproxyfen®, Sitara®, Viper®, Track®, and Priority®. These IGRs, known as reduced-risk pesti...cides, target pest juveniles and are less harmful to beneficial insects. Conducted through a Randomized Complete Block Design (RCBD) with 24 treatments, excluding a control group, the study recorded maize stem borer populations at 3, 7, and 14 days post-IGR application. In conclusion, the study identifies pyriproxyfen® and Priority® at double the standard concentrations as highly effective insect growth regulators in mitigating maize stem borer infestations, offering promising avenues for enhanced pest control strategies in maize cultivation.Read more

The current study examines the impact of integrating artificial intelligence (AI) in higher education in Saudi Arabia, specifically focusing on the roles of university teachers and students’ learning outcomes. It investigates the transformation of teaching practices, and the challenges faced by university teachers during AI integration, and identifies opportunities for collaboration and innovation. A quantitative research method using a survey questionnaire was employed to gather data and inform practical recommendations. The findings ind...icate that university teachers recognize the potential benefits of AI in education, but also highlight the need to address challenges for effective implementation. Participants perceive AI as a tool that enables more creative and engaging teaching methods, automates tasks, and brings about changes in teaching approaches. Difficulties in utilizing AI effectively and adapting to new teaching methods were identified. AI also offers opportunities for innovation, collaboration, and creating engaging learning environments. There were slight variations in perspectives based on gender and current role, with female university teachers and teaching assistants/professors perceiving higher impact and opportunities for collaboration and innovation. Participants with higher AI expertise perceived a greater impact of AI and fewer challenges. Those who aligned with the educational purposes of AI saw greater impact and opportunities for collaboration while acknowledging usage difficulties.Read more

The pervasive Internet of Things (IoT) integration has revolutionized industries such as medicine, environmental care, and urban development. The synergy between IoT devices and 5G cellular networks has further accelerated this transformation, providing ultra-high data rates and ultra-low latency. This connectivity enables various applications, including remote surgery, autonomous driving, virtual reality gaming, and AI-driven smart manufacturing. However, IoT devices’ real-time and high-volume messaging nature exposes them to potential m...alicious attacks. The implementation of encryption in such networks is challenging due to the constraints of IoT devices, including limited memory, storage, and processing bandwidth. In a previous work [1], we proposed an ongoing key construction process, introducing a pivotal pool to enhance network security. The protocol is designed with a probability analysis to ensure the existence of a shared key between any pair of IoT devices, with the predefined probability set by the system designer. However, our earlier model faced vulnerabilities such as the “parking lot attack” and physical attacks on devices, as highlighted in the conclusion section. We present a complementary solution to address these issues, fortifying our previous protocol against cyber threats. Our approach involves the implementation of an internal Certification Authority (CA) that issues certificates for each IoT device before joining the network.Furthermore, all encryption keys are distributed by the primary IoT device using the Unix OS ‘passwd’ mechanism. If a device “disappears,” all encryption keys are promptly replaced, ensuring continuous resilience against potential security breaches. This enhanced protocol establishes a robust security framework for IoT networks, safeguarding against internal and external threats.Read more

Fractals are complex structures that repeat themselves at several scales. Nature exhibits these in many forms like snowflakes, mountains, coastlines, the human brain/lungs/ nervous system, and many more. It appears that these are nature’s organic way of growth. Thus, there is an underlying science that works to grow or create these self-similar patterns. In this work, tin oxide-based fractals have been grown under laboratory conditions and applied to a gas-sensing field. The facile growth methodology successfully grows fractals on a large... scale. The tin oxide fractals have unique basic building units that connect and grow in different directions. These tin oxide fractals have successfully sensed ethanol vapors in the range of 20 ppm to 100 ppm. The best sensing response has also detected ethanol vapors as low as 10 ppm at room temperature with response and recovery times of 18 ± 3 s and 22 ± 5 s, respectively. The best sensing response recorded for such sensors was under 12 s. The characteristic fractal growth is attributed as the defining factor that enhances ethanol sensing at room temperature.Read more

Today’s cadet leader is tomorrow’s officer, a professional capable of integrating knowledge and solving complex problems in a full-scale war with incomplete information, being a leader and authority for the personnel. Most of the time, cadets study in study groups using traditional technology, which is not enough to form a professional cadet leader. With the advent of computer technology, students’ and cadets’ motivation to learn using traditional teaching methods has paradoxically begun to decline rapidly. The problem o...f the quality of training of military specialists for the needs of communication and cybersecurity units is not reflected in the publications reviewed. However, significant progress has been made in the use of computer technology as the basis of training tools for ground forces units. Similar training complexes are actively used in NATO member states in the military education system in the training of air force pilots (navigators). Therefore, the author chose the improvement of the educational process at the Department of Combat Use of Communication Units in combination with the methodology of professional-business game for the development of a cadet leader in professional training courses (L-1B) of the tactical level of military education as the direction of research. The purpose of the study and the article is to substantiate the conceptual view of the department in the need to build a computerized training complex for training officers of leaders in professional training courses (L-1B) of the tactical level of military education, capable of using communication units based on computer games. Fragments of the game mechanics of stimulating the interest and motivation of cadets to study, for example, electronic shooting range, and learning Morse code, are considered. Game mechanics is a proof of a professional business game in the course of the discipline: Combat use of military communication systems and complexes of the course of professional military education (professional course of tactical level L1B).Read more

Many UK inhabitants now adopt careers working in both university and manufacturing sectors. In a typical engineering career, a young student may now start at university, spend time in factories, often in research and development, and then return to university in later life to teach evolving innovation principles of industry. It is clear to such people that universities are expanding rapidly whereas manufacturing has declined and reached an equilibrium of output but with lower job numbers due to robotics. Manufacturing in 2022 was approximately ...8% of British GDP whereas the university sector was only about 2%. This paper analyses the growing connections and co-locations with numerous universities/manufacturing companies, predicting that convergence in both jobs and GDP contribution will occur around 2050.Read more

The governing equations for the shear stress corresponding to some magnetohydrodynamic (MHD) motions of a large class of rate-type fluids are brought to light. In rectangular domains, the governing equations of velocity and shear stress are identical as form. The provided governing equations can be used to solve motion problems of such fluids when shear stress is prescribed on the boundary. For illustration, the motion in an infinite circular cylinder with shear stress on the boundary is discussed.

The operating experience of mechanical seals shows that as a result of angular deformations of the rings, the wear of the contact surfaces along the radius is uneven. When designing mechanical seals, it is necessary to calculate the amount of expected leakage through the seal, friction power consumption, as well as the possible durability of the unit. These calculated dependencies and estimates are obtained based on the constructed mechanical seal model. In the area of hydrodynamic load support in the case of a confusor joint or a converging fi...lm, the slope of the pressure diagram is such that a decrease in the film thickness increases the hydrodynamic support. This is referred to as enabling stable non-contact sealing operation. The execution of the rubbing surfaces of the interface of the end pair should ensure the formation of the calculated confusor shape of the sealing gap in all modes of operation and axisymmetric pressure fields during the rotation of the rotor.Read more

Background: Firefighters are subject to a variety of stressors, hence the importance of equipping them with resources that contribute to the management of these stressors. Aims: Considering that a healthy lifestyle is one of these resources, this study aimed to characterize the lifestyle of a Portuguese firefighters sample, rate their general lifestyle level, and analyze its association with their subjective well-being (i.e., flourishing). Methods: A sample of 860 firefighters responded to an adapted version of the FANTASTIC. Res...ults: The results showed that most (72.8%) had a good lifestyle. However, regarding each habit, a significant percentage had bad habits: sometimes consuming high-calorie foods (81.2%); sometimes having difficulties sleeping (50.9%); drinking more than 4 - 5 alcoholic drinks on the same occasion (43.9%); and exceeding their ideal weight by more than 8 kg (29.7%). However, a marked percentage also had healthy habits: having people to talk to (71%) and giving and receiving affection (63.5%); exercising at least once a week (81.5%); not smoking (63.9%); almost always eating healthily (26.7%); sometimes sleeping well (50.2%); and managing stress (56.7%). As expected, the assumption that firefighters’ lifestyle is related to their flourishing was supported. Conclusion: A healthy lifestyle is an important resource to ensure the firefighters’ flourishing and should be a part of the day-to-day life of these professionals.Read more

Smooth muscle tumours are the most common mesenchymal tumors of the vulva and vagina, yet their infrequency is demonstrated by the prevalence of published reports as individual cases or small case series.This article reports a case of a 42-year-old woman who presented with apparently recurrent vulvovaginal leiomyoma and a past history of surgical excisions. Histopathology revealed Smooth Muscle Tumor of Uncertain Malignant Potential (STUMP).
