Published: April 2024

This research paper discusses the development of the APOK (Automatic Faucet Closing Device) utilizing the Internet of Things (IoT) as a novel approach to enhance the convenience and efficiency of water use. APOK was developed to automatically close the tap when not in use by incorporating motion sensors and voice recognition technology, the results of which will be transmitted via the ESP32 module. Furthermore, this solution allows real-time water use monitoring via a mobile application or web dashboard constructed on the Blynk program, which is compatible with the ESP32 module. By emphasizing water conservation, user comfort, and awareness of the environment, APOK has the potential to contribute to the preservation of water and sustainable resource management. While challenges such as data security and IoT infrastructure availability need to be addressed, APOK implementation presents beneficial changes in how we see and manage our daily water consumption.

The use of support vessels significantly increases the cost of monitoring objects of underwater production complexes (UPC), and the presence of a cable communication line significantly limits the possibility of using remote-controlled uninhabited underwater vehicles (ROV), which is reduced to zero in conditions of continuous ice coverage of the work area. An obvious alternative to the use of ROVs are autonomous uninhabited underwater vehicles (AUVs), equipped with equipment for conducting contact work with monitoring objects and communicating with the shore control post. At the same time, the necessary autonomy for the use of such hybrid autonomous uninhabited underwater vehicles (HAUVs) can be ensured by a network of bottom stations equipped with systems for contactless charging and information exchange with the shore UPC control post. The work proposes the concept of an underwater service station (USS) for a HAUV, which allows, in long-term underwater deployment conditions, to use the device not only in an autonomous mode, but also in a remote control mode from a shore control post. A model for using the station for its intended purpose and the composition of the equipment necessary for its implementation have been determined, the design of the technical solution of the station has been presented, determined taking into account the features of installation on a complex bottom surface and the requirements for docking the HAUV for contactless charging and information exchange, including in the mode of remote control from the SCP. Basic technical solutions for the USS have been developed that provide automatic adjustment of the horizontal position of the docking unit, reliable docking and holding of the HAUV charging and information exchange terminals, and control of the vehicle’s pointing process using a set of rotary video cameras with lamps and a sector-view sonar. Algorithms for interaction between the station and the HAUV have been developed for autonomous and controlled via optical communication cable operating modes of the vehicle.

Vortex fields are the most complex and least studied objects in the acoustics of layered media. They significantly complicate the structure of the sound field due to the appearance of nodal and saddle points in it, in the vicinity of which the concept of the phase of the sound wave becomes uncertain. Therefore, such special points of the sound field are usually called phase front dislocations. In turn, the dislocation structure of the vortex field is most complex in waveguides, which play an extremely important role in theoretical and applied hydroacoustics. In this work, the vortex structure of the sound field and the corresponding dislocation structure of the vortex field are analyzed using the example of a Pekeris waveguide, the sound field in which is constructed within the framework of a non-self-adjoint model formulation of the corresponding boundary value problem.

The problems of ensuring the safe motion of a large autonomous underwater vehicle (AUV) when it passes through sections with different environmental conditions are considered by the example of the development of the Northern Sea Route. An analysis was made of the influence of various environmental conditions - open and coastal water, fast ice and ice conditions - on the safety of the operation of a large AUV. An approach is proposed to assess the vehicle safety in various environments using a dynamic Bayesian network and conditional probability tables. To test the algorithms for controlling the the vehicle motion and the vehicle itself, a digital test site was developed in the form of a stand for simulating the functioning of the AUV. The development of digital twins in the form of software simulators of the vehicle devices and mechanisms made it possible to test control algorithms on the simulation stand both during normal operation of its systems and in the event of malfunctions due to functioning in various environments. The results obtained on a simulation stand for a large AUV operating on the farthest and most complicated part of the Northern Sea Route - the Vilkitski Strait, helped us to assess the safety of the vehicle operation and outline the ways to improve the safety by upgrading the algorithms for controlling the AUV motion in difficult environmental conditions.

Authors: Ghifari Muhammad
Published: April 2024

The existence of the impact of COVID-19 last year has brought quite significant changes to the order of human life throughout the world. These changes or transformations are very important to pay attention to. On the other hand, the existence of values ​​in Islam believed by its adherents is considered capable of overcoming the problems of the impact of COVID-19. There is a popular adage about Islam as a religion of mercy for the entire universe (rahmatan lil al‑‘ālamīn) and always relevant to all developments in the temporal and local context (al‑Shālih li kulli al‑Zamān wa al‑Makān) often used as the theological foundation of Muslim society in their lives. In this context, is it true that Islam can overcome the impact of COVID-19? Then how should Islam itself be realized? Therefore this research offers the concept of Islamic renewal to be realized in the post-COVID-19 era. This research also uses a philosophical approach and a method of critical analysis of certain concepts in Islamic studies. The results of this study indicate that there are demands for change and innovation in the theory of Islamic thought compatible with the spirit of changing times. More than that, this innovation is then formulated by presenting the idea of ​​“Islamic Science” as a model for dealing with the current impact of COVID-19.

Authors: Mohamed Mohamed Hassan
Published: April 2024

Examining Somalia's journey from political instability to economic recovery, this analysis focuses on the significant impact of recent efforts to relieve the country's debt burden. A major achievement was Somalia's successful inclusion in the Heavily Indebted Poor Countries (HIPC) initiative, which granted the nation relief from repaying its debts. This article aims to explore the complex landscape, thoroughly examining the essential role of debt relief. It dissects the factors contributing to economic stability, evaluates the newfound global confidence, analyses elements enhancing investor appeal, and navigates the challenges and opportunities defining the nation's economic resurgence. The challenges arising from the debt write-off include the effective implementation of economic reforms, managing heightened expectations, and addressing the persistent historical political instability that requires ongoing attention. Despite these challenges, opportunities emerge, providing Somalia with the chance to strategically reallocate resources to vital sectors, enhance its attractiveness to investors, and engage in potential global collaborations. This exploration concludes by outlining policy implications for Somalia's policymakers. It emphasizes the importance of sustainable economic reforms, initiatives promoting political stability, prudent resource allocation, the implementation of investor-friendly policies, active participation in international collaborations, and targeted efforts to promote investment. Addressing these policy implications could empower Somalia to transform challenges into catalysts for sustained economic growth and development, charting a course toward a prosperous and resilient future

The article discusses new requirements for the characteristics of microgeometry of the working surfaces of machine parts in accordance with GOST R ISO 25178-2— 2014. It is shown that in order to calculate such characteristics, it is necessary to have information about the three-dimensional distribution of the microrelief parameters, that is, to move from the profile parameters of microgeometry to the parameters of its structure. In this regard, the article considers the application of a software method for forming a surface structure based on profilograms obtained by simpler devices.

The process of mass development of cyanobacteria has a negative impact on the ecological state and water quality of the reservoirs of the Volga-Kama cascade, which are used for drinking water supply, fisheries and recreation. The main goal of the research is to assess the impact of the mass development of cyanobacteria on the formation of water quality using the example of the Kuibyshev reservoir in the context of global warming. Comprehensive observations were carried out in the period 2001-2021. on the largest in Europe Kuibyshev reservoir with seasonal, weekly and daily regime of water line regulation. The research results show that during the period of "water bloom" organic water pollution increases. So permanganate oxidation in summer exceeds the permissible value by 1.5-2.0 times, which creates problems in providing the population with high-quality drinking water. The mass development of cyanobacteria disrupts the oxygen regime of the reservoir. The seasonal variability of the dissolved oxygen concentration includes four periods, which differ in the different directions of the processes of formation of the oxygen regime. Within the year, two minima of the dissolved oxygen content are observed: winter and summer. In the summer minimum, the concentration of dissolved oxygen decreases to critical values, and is 4-5 mg/dm3. The mass development of cyanobacteria has a significant influence on the formation of the summer oxygen minimum. As a result of photosynthetic aeration, a thin surface layer of water supersaturated with oxygen is formed, which disrupts the process of oxygen absorption from the atmosphere in a significant part of the reservoir water area. Under conditions of growing nutrient load and global climate warming, the intensity and scale of the process of mass development of cyanobacteria in the Kuibyshev reservoir will only increase, which will lead to a further increase in oxygen deficiency, deterioration of water quality and the emergence of water use risks.
