Freedom of creativity in the system of constitutional rights and freedoms (in the light of the 2020 constitutional reform)
Authors:   Saratov State University, Chulisova Yulia A.
Published: September 2024

Introduction. Despite the static nature and immutability of the norms of Chapter 2 of the Constitution of the Russian Federation, it seems possible to talk about a certain dynamics in the development of the content of human and civil rights and freedoms. The rethinking of the norms of the Constitution of the Russian Federation is aimed at improving and updating legislation, law enforcement and the mechanism for protecting human and civil rights and freedoms. Theoretical analysis. Freedom of creativity should be considered as a constitutional and legal institution, including the normative and legal regulation of relations between the state and citizens engaged in creative activities and their associations, establishment of principles of such relations, guarantees, restrictions and measures to support and develop creative abilities of the individual, evaluation of the results of creative activity as a socially significant product, and as subjective freedom, with non-interference of the state in self-determination of the individual in matters of creative activity and protection of his / her rights to the results of intellectual activity being its guarantees. Empirical analysis. The constitutionalization of spiritual and moral values has been reflected in modern Russian policy of regulating relations related to freedom of creativity, support for culture, and protection of national cultural identity. As a result of the constitutional reform, the coordinate system of the spiritual and moral development of society was fixed, which cannot but affect the system of evaluating the results of creative activity, and the public demand for the reflection of spiritual, moral and socially oriented values in the results of creative activity was clearly expressed. Results. Freedom of creativity acts as a guarantee of a number of constitutional human rights and freedoms established by the Constitution of the Russian Federation. The key principles, goals and objectives of preserving and multiplying the cultural heritage and spiritual and moral development of Russia, strengthening its civilizational identity in conjunction with freedom of creativity run like a red thread through all levels of legislation, finding conceptual development in federal laws and federal subordinate regulatory legal acts. These normative acts specify guidelines for the implementation of creative freedom and mechanisms for supporting creative projects aimed at the development of statehood, patriotism and preservation of values.

Published: September 2024

Curup Kereta Waterfall Ecotourism in Rambang Jaya Village is a community-managed tourist destination and one of the favorite attractions in Way Kanan, Lampung. This research aims to analyze the social practices in the development of community-based ecotourism at Curup Kereta Waterfall from the perspectives of structure, agency, and interaction. The study employs a qualitative research method. The findings indicate that the social practices in developing Curup Kereta Waterfall ecotourism in Rambang Jaya Village are significantly influenced by domination, significance, and legitimacy within the local community dynamics. The village head's family's dominance is evident in their control over land management and major decision-making processes. This dominance is accepted by the community due to the sekelik system in Lampung culture, which strengthens family bonds as the community members consider each other as relatives. Decisions made by the village head's family are seen as being for the common good and are accepted without social envy. The sekelik system also provides social significance, ensuring continuous community involvement in ecotourism activities. The community feels a shared responsibility to support and promote ecotourism, thereby reinforcing social solidarity essential for the sustainability of ecotourism. The legitimacy stems from strong kinship ties and a sense of togetherness, with the community trusting that the village head's family will manage the ecotourism fairly and wisely.
Fixed Switching Frequency Model Predictive Control for Parallel Inverters in Microgrids
Authors: Carnielutti Fernanda , Aly Mokhtar , Norambuena Margarita , Hu Jiefeng , Guerrero Josep , Rodriguez Jose
Published: September 2024

A Fixed-Switching-Frequency Model Predictive Control (FSF-MPC) for Master-Slave inverters in microgrids is proposed in this paper. The Master is a three-phase, two-level inverter with an LC filter, while the Slave is a three-phase, two-level inverter with an LCL filter. The inverters are connected in parallel in a microgrid, composed of different loads. The voltage and current inner control loops of the Master-Slave FSF-MPC are presented for both inverters. Then, two modes of operation are proposed: grid-connected and islanded, and the primary control for both cases is developed. Finally, Hardware-in-the-Loop (HIL) results are presented for different operational conditions of the microgrid with load-related disturbances. The HIL results validate the good performance of the proposed Master-Slave FSF-MPC, including fast dynamic response, multi-objective control, and fixed switching frequency.
Increasing efficiency of technological processes in oil production based on innovative rheotechnologies
Authors:   Azerbaijan State Oil and Industry University, Mammadova Yevgeniya V.
Published: September 2024

Numerous studies by various authors have been devoted to gas lift wells. The scientific literature has addressed issues of increasing production of both Newtonian and non-Newtonian oils. Despite these efforts, the efficiency of the gas lift method remains relatively low, necessisating novel approaches. One of the methods to increase the productivity of gas lift wells may be the use of innovative rheotechnologies. Rheotechnology laverages knowledge about the rheological properties of formation fluids to address specific technological problems. This paper describes studies of non-Newtonian oils, their rheological properties, and their impact on the technical and economic indicators of gas lift wells. The analysis showed that by studying the formation of the non-Newtonian structure of oil, it is possible to influence its relaxation properties, and thus obtain the movement of an abnormal oil (anomalous fluid), both in the bottom-hole zone of the well and in the lifting pipes. The results of experimental studies showed that viscoelastic crude oil flowing into the wellbore contains an increased volume of reservoir gas, which, along with the injected working agent, perform additional work in lifting gas-liquid mixtures to the surface. During gas lifting operations, phenomena such as breakthrough and slippage of the working agent can be observed. Addressing all these factors enables better control over gas lift well operations and, consequently, improves the efficiency of the tecnological processes.

Russian State Terrorism and State Sponsorship of Terrorism
Authors: Rekawek Kacper
Published: September 2024

The field of terrorism studies has traditionally been focused on non-state perpetrators of violence, such as different jihadi organisations which have been active in the West in the last three decades. Things looked different, however, during the Cold War, when state actors actively involved themselves in terrorism by, for example, supporting terrorist organisations operating abroad. This report takes stock of Russia’s return to such a paradigm in the twenty-first century in general and after 2022, the onset of the Russian full-scale aggression against Ukraine, in particular. Russia not only terrorises its own population into submission but also uses homegrown terrorists for the domestic ends of Vladimir Putin, deploys terrorist tactics while fighting against Ukraine, and seems increasingly willing and able to use those tactics as part of its foreign policy toolbox in its “political warfare” against the broader West. For this reason, it is argued that one could seriously consider labelling Russia a “state terrorist” or a “state sponsor of terrorism.” The report concludes that this might prove challenging in 2024, but also offers a way forward for prosecuting, sentencing, and arresting individuals involved in Russian state terrorism and state sponsorship of terrorism.

Published: September 2024

The traditional industry synthesizes urea through the reaction of NH3 and CO2 under high temperatures and pressure. Electrochemical catalysis, which could replace the traditional ammonia synthesis route, i.e., co-reduces carbon dioxide with nitrogen sources [nitrite (NO2-), nitrate (NO3-), nitrogen (N2), and nitric oxide (NO)] to synthesize urea, is a promising strategy for the synthesize of urea under environmental conditions. Unlike traditional industry routes, electrochemical catalysis urea synthesis is beneficial for both resource utilization and environmental protection. Herein, the recent research progress of electrocatalytic urea synthesis is summarized, with emphasis on the design and preparation of the catalyst for the coupling of CO2 and nitrogen species directly to urea. The involved reaction mechanism of C-N coupling is generalized and discussed. Furthermore, the difficulties and challenges at the present stage are summarized, and the development direction of electrocatalytic synthesis of urea is prospected.

Authors: Muhsin Ilyya , Achmad Maimun  , Sukron Ma’mun
Published: September 2024

The diversity present in Nalen is a blessing, as it fosters cohesion in social, cultural, and religious ties, in contrast to the various conflicts that often arise from such differences. This cohesion resulted from the formation of a habitus of peace. This study aimed to answer the question of how the habitus of peace is cultivated in Nalen, a small village in Central Java. Data were systematically collected through in-depth interviews with prominent figures and community members in Nalen, complemented by observations. The subsequent analysis of the data employed Bourdieu’s theoretical framework, which delves into the intricacies of habitus development within the Nalen community. This analysis scrutinizes various forms of capital, with a particular emphasis on social and cultural capital, substantively contributing to the fortification of the habitus. This study finds that the habitus of interreligious harmony can manifest organically, devoid of external coercion, showcasing the community’s robust autonomy in the formative process. Additionally, the objective and subjective structures of society, alongside historical factors, emerge as foundational elements that influence the trajectory of habitus formation. Ultimately, habitus is cultivated within the collective consciousness of the community and is sustained by the diverse capital resources at their disposal.

Unity in Diversity of Religions in Bumi Flobamora, Indonesia: From Traditional to Modern Pluralism
Authors: Jegalus Norbertus , Atang Ahmad , Binsasi Norbertus Antoin
Published: September 2024

The religiously diverse society of NTT (Bumi Flobamora) has received national title as the most tolerant province in Indonesia. However, reality shows that there are religious conflicts, such as the rejection of the establishment of Islamic places of worship and the emergence of various forms of violence with religious nuances. This study attempts to provide a new contemporary social philosophy explanation for the development of religious social conditions. With the help of philosophical methods, the results show that the ideology of pluralism has long lived in Bumi Flobamora. However, this model of "traditional pluralism,” which is based on local wisdom and supported by the government's policy of harmony, is currently no longer in line with demands for universal human rights, because "traditional pluralism" shows the unequal treatment of people of different religions. Therefore, contemporary social philosophy develops a "modern pluralism,” which is built on the principle of equality. To strengthen this new model of pluralism, efforts are needed to overcome the weaknesses of communitarianism. The main weakness of communitarianism is that it opens up a space for religious appreciation that only emphasizes the togetherness and unity of a spiritual community and views those outside the community as other people who may or should even be excluded. The study concludes that the unity of religions in Bumi Flobamora will only survive if traditional pluralism is replaced with modern pluralism, which is in line with the Political Ethics of the Indonesian nation, Bhinneka Tunggal Ika, and the basic philosophy of Pancasila.

Published: September 2024

Life Cycle Assessment (LCA) is a widely used tool to measure the environmental sustainability of products or processes. Integrating LCA into the assessment of waste diversion strategies recognizes current waste diversion strategies are insufficient to effectively stem the global impacts of waste particularly with increased pressure to recover organic and inorganic materials to reduce landfill impacts and promote the circular economy. Historically, waste diversion efforts in municipalities and industries focused on higher-profile inorganic wastes, such as plastics and other recyclables. However, organic waste is increasingly identified as a key waste fraction that must be effectively managed and regulated. This research surveys published LCA studies from 2019 to 2023 focusing on the anaerobic digestion (AD) of organic waste. Notable conclusions include the lack of studies comparing AD with the latest treatment options such as co-gasification; the insufficient attention to the LCAs on biogas upgrading methods; and the monetization of LCA results using carbon credits. In addition, more than 50% of reviewed LCA studies concluded the results with a sensitivity analysis which was not a common practice before 2019 in LCA studies in anaerobic digestion. This signifies the increasing need to understand uncertainty in the circumstances governing applying AD to wastes. Finally, neglecting the combined effect of several parameters in sensitivity analysis might have reduced the accuracy of the sensitivity analyses in the reviewed LCAs. Overall, LCAs conducted on AD-related applications vary widely in terms of scope and consistency, implying that the outcomes may not be as applicable as intended. The identified challenges, issues, and other findings related to this research are expected to help standardize LCA procedures as applied to AD to promote greater comparability.

Published: September 2024

Minimizing optical losses in resonant cavities is crucial for improving photonic device performance. This study focuses on the development of a simulation tool to analyze scattering losses in Fabry-Pérot interferometers (FPI), offering precise modeling of waveguide dynamics and contributing to accurate loss predictions across various platforms. Optical cavities often suffer from scattering losses due to surface roughness and material defects. Our approach integrates theoretical models and simulations to quantify these losses, utilizing the FPI as a model system. We identified upper and lower reflectivity thresholds, beyond which accurate measurement of losses becomes unreliable. For reflectivity below a certain threshold, measurement errors arise, while excessively high reflectivity can reduce fringe visibility and introduce detector sensitivity issues. Simulations were used to validate the model's ability to predict reflectivity and attenuation in waveguides with varying loss levels. The software’s flexibility to adjust transmission parameters for different cavity configurations enhances its utility for a broad range of photonic systems. Our study offers a novel methodology for optical loss analysis, with practical applications in optimizing photonic devices. By providing a reliable tool for precise loss measurement, this work supports advancements in optical technologies, enabling the design of more efficient, high-performance devices across various applications.

Published: September 2024

Aiming at the problem of underactuated unmanned surface vehicles (USVs) performing fixed-point operations in the sea but without dynamic positioning control system. This paper introduces an original approach for positioning control, and the method is named as virtual anchor control method. This method is applicable in slow-varying current environments, and this approach does not need the prior knowledge of current information or vessel motion model parameters, thus offering convenient usability. This method is comprised by four steps. Firstly, a linear concise motion model with unknown disturbances is proposed. Then, the motion planning law is designed by imitating underlying principles of ship anchoring. Next, an adaptive disturbance observer is proposed for estimating uncertainties in the motion model. Last step, based on the observer, a sliding-mode method is used for heading control law designing, and thrust control law is also conducted by applying the Lyapunov method. Finally, numerical simulation experiments with significant disturbances and tidal current variations are conducted, which demonstrate that the proposed method has good control effect and robustness.

Published: September 2024

In the field of music education, the incorporation of technology originally designed for professionals presents both significant opportunities and challenges. These technologies, although advanced and powerful, are often not adapted to meet the specific needs of the educational envi-ronment. Therefore, this study details the design and implementation process of a system con-sisting of a hardware device called "Play Box" an associated software, "Imaginary Play Box". The Design Sciences Research Methodology (DSRM) specifically adapted to software development was used to structure the project. The three phases shown in this study ranged from the conception of an initial prototype to the realisation of a working software.
During the design phase, a questionnaire was developed to evaluate various aspects of the soft-ware, such as the visual interface, the programming of components and the sound interactivity provided by the Play Box. The technique of panels of experts in music pedagogy and program-ming in MAX-MSP was used to obtain critical feedback. This expert evaluation was crucial to it-erate and polish the software, culminating in a beta version optimised for the creation of electro-acoustic music for music education.

Published: September 2024

Parkinson's disease (PD) is the second most common neurodegenerative disorder, entailing several motor-related symptoms that contribute to a reduced quality of life in affected subjects. Recent advances in wearable technologies and computing resources have shown great potential for the assessment of PD-related symptoms. However, the potential applications (e.g., early diagnosis, prognosis and monitoring) and key features of digital biomarkers for motor symptoms of PD (DB-MS-PD) have not been comprehensively studied. This study aims to provide a state-of-the-art review of current digital biomarker definitions for PD, focusing on the use of wearable devices. This review systematically examines research articles from 2012 to 2024, focusing on key features and recent technologies in PD research. A total of 22 studies were included and thoroughly analyzed. Results indicate that DB-MS-PD can accurately distinguish patients with PD (PwPD) from healthy controls (HC), assess disease severity or treatment response, and detect motor symptoms. Large sample sizes, proper validation, non-invasive devices, and ecological monitoring make DB-MS-PD promising for improving PD management. Challenges include sample and method heterogeneity and lack of public datasets. Future studies can leverage evidence of the current literature to provide more effective and ready-to-use digital tools for monitoring PD.

Published: September 2024

The microfluidic industry recognizes the lack of sensitive and standardized testing methods as one of the major hurdles to overcome before fulfilling its revolutionary promises. Highly ranked upon the list of things in need of testing methods are the internal dimensions of microfluidic structures after chip assembly. This work, performed under the MFMET project, aims to address this challenge by presenting and comparing multiple protocols for measuring the dimensions of internal microfluidic channels of fully assembled transparent chips. The protocols include optical profilometry, optical microscopy and tiled digital imagery. Several standardized chip designs out of two different materials commonly used in microfluidics (D263©bio and TOPAS© COC) were measured by the different protocols. A consistency analysis through normalized error statistics revealed optical profilometry as the preferred method due to its low uncertainty compared to the other protocols and its higher consistency with nominal geometry values. All protocols showed difficulty with vertical depth measurements of internal structures. Associated possible directions of future research are considered including further study of the influence of multiple refractive surfaces on optical profilometry measurements and further investigation of confocal microscopy as a potential measurement method showing promising preliminary results. The influence of the different materials appears to be minimal on optical profilometry, but other materials and method would merit looking into before such an observation might be generalized. In conclusion, the results of this work directly address the current lack of measurement methods for internal microfluidic structures by providing a comprehensive comparison of different protocols, ultimately suggesting a preferred option for immediate application within the microfluidic industry. Additionally, this work offers valuable directions for future research, serving as an initial step in overcoming a significant challenge that impedes the microfluidic industry from realizing its revolutionary potential.

Published: September 2024

Using different frequency group period phase synchronization, a precise frequency detecting technology is presented. On the basis of the phase comparison for different frequencies, a high-accuracy frequency measuring can be achieved by quantization of phase comparison results and analysis of quantization results. Using the phase coincidence points between comparison signals as the counter’s open and close signals, the time interval between the same phase coincidence points is a group period. Via the detection and analysis of the phase coincidence points, the ±1-word counting error can be eliminated, and measuring speed is also improved. By using FPGA technology, the measuring device can be simplified, and the development cost can be reduced. Testing results indicate that the frequency measuring accuracy with 10−13/s level can be achieved. The technology is greater than the common frequency measuring technology in more ways than one, such as power consumption, device volume, measuring rate, etc., so it plays an important role in Beidou satellite positioning, precise timing, high-precision time frequency transfer and comparison, scientific metrology and other fields.

Reminding the courier through wearable artificial intelligence devices to prevent accidents is not only beneficial to the courier's safety but also will save a lot of insurance premiums for express companies, therefore, it is worth investigating what factors can influence the acceptance of wearable artificial intelligence devices by couriers. Push-pull-mooring (PPM) theory and affective event theory (AET) are integrated to test couriers’ adoption to wearable safety detection devices. Social influence, perceived security, personal innovativeness and affective event reaction are applied to research model. Questionnaires are distributed among several listed express companies and 263 valid questionnaires are used for empirical test. Empirical results indicated that social influence, perceived safety, personal innovativeness and affective event reaction are positively related to usage with coefficients 0.218, 0.301, 0.698 and 0.309. Personal innovativeness has positively moderating effects on relationships between affective event reaction, perceived security and usage with coefficients 0.145 and 0.106, whereas has no significant moderating effect on relationship between social influence and usage. The research aims to help support the proliferation and adoption of wearable artificial intelligence devices to optimize the current state of the express industry and improve the interaction between couriers and managers, creating an active management strategy that will allow express companies to thrive. This study can help express companies reduce insurance costs and therefore reduce the premium pricing of insurance companies for the courier industry.. This study also provides design suggestions for the application of wearable artificial intelligence devices based on chat GPT in various working conditions.

As a critical component of electric vehicles, the powertrain has a significant impact on the overall performance of the vehicle. In addressing the challenge of lengthy testing cycles, this study develops a para model of the powertrain utilizing digital twin (DT) technology, thereby establishing a framework for simulation testing of multi-controller intermodulation. The research conducts functional definition coverage testing through the design of specific functional requirement use cases, and it validates the failure mechanism via fault injection use cases. The results indicate that the DT testing platform can effectively simulate the operational interactions among various controllers within the powertrain system. In comparison to traditional field testing, the digital twin-based testing methodology offers enhanced operational efficiency and allows for the examination of testing conditions that are impractical to implement in real vehicles, particularly in the context of fault injection testing, thus facilitating the early detection of potential safety risks within the system. The advancement of this technical solution holds significant practical implications for the future mass production and development of electric vehicles.
A Machine Learning Pipeline for Predicting Wine Quality from Viticulture Data: Development and Implementation

Published: September 2024

The quality of wine depends upon the quality of the grapes, which, in turn, are affected by different viticulture aspects and the climate during the grape-growing season. Obtaining wine professionals’ judgments of the intrinsic qualities of selected wine products is a time-consuming task. It is also expensive. Instead of waiting for the wine to be produced, it is better to have an idea of the quality before harvesting, so that wine growers and wine manufacturers can use high-quality grapes. The main aim of the present study was to investigate the use of machine learning aspects in predicting wine quality and to develop a pipeline which represents the major steps from vineyards to wine quality indices. This pipeline outputs the predicted yield, values for basic parameters of grape juice composition, values for basic parameters of the wine composition, and quality. We also found that the yield could be predicted because of input data related to the characteristics of the vineyards. Finally, through the creation of a web-based application, we have investigated the balance berry yield and wine quality. Using these tools further developed, vineyard owners should be able to predict the quality of the wine they intend to produce from their vineyards before the grapes are even harvested.
