Market demands vs. scientific realities: A comparative analysis in the context of BIM-based and user-centred lighting control

Real utilisation patterns often only become apparent when a building is put into operation. Since planning is therefore based on several assumptions, the potential of building technology is often limited. Post-occupancy evaluations offer the potential to adapt operation to real usage patterns and draw conclusions for future planning, thereby improving performance. Although solution approaches are available in the literature, this potential is currently hardly being utilised. A survey in the construction industry is therefore used to compare market requirements with existing solution concepts. The results emphasise the relevance of auto-commissioning, contractual agreements on performance evaluation and the coupling of digital twins with post-occupancy evaluations. A stronger anchoring of the control industry in BIM is proving to be necessary for better cross-disciplinary collaboration between all parties involved. Even though the focus of this study is on lighting, the most important findings are in principle transferable to other trades.

Monitoring and assessment in the context of governance of nature-based solutions. Shared challenges and opportunities in CELAC and EU cities

The concept of Nature-based Solutions (NbS) has gained interest as an approach to make significant contributions to the transformation towards more liveable, sustainable, and climate-resilient cities. However, the uptake of NbS into urban development practice is hindered by knowledge and governance barriers. Knowledge plays an essential role in evidence-based decision-making processes and in building the capacity to co-design sustainable pathways. In turn, governance processes can greatly support the acquisition, dissemination and application of knowledge. However, little is known about how these interactions between governance and knowledge manifest in practice. Therefore, we aim to understand the interplay between governance and monitoring & assessment (M&A) and the associated challenges and opportunities for NbS implementation in European and Latin American cities. Considering different socio-economic and cultural contexts allows us to draw from a wider range of practitioners’ experiences in different governance settings. We conducted an explorative qualitative content analysis on ten semi-structured expert interviews with thirteen city experts from local governments and academia based in seven cities: Bogota (CO), Buenos Aires (AR), Santiago (CL), São Paulo (BR), Barcelona (ES), Lisbon (PT) and Turin (IT). Our findings show that M&A provides agency for individual, institutional actors to steer political commitment and can support integrated working. The potential of collaborative M&A with non-governmental actors is still largely untapped, which requires acknowledgement of the capacities of non-governmental actors to contribute to M&A and raise awareness of the value of M&A to civil society. Furthermore, we recommend integrating more reflective learning opportunities in M&A processes, paying more attention to data sharing, and considering of more feasible M&A processes.

ABOUT SOME PROBLEMS OF THE ELECTRIC ENERGY SECTOR OF GEORGIA

In the article - "About some problems of the electric energy sector of Georgia" - the issue of the country's electricity production potential and how it is used is discussed. The article mentions that out of all the energy resources, Georgia has the most electrical energy resources. These are hydropower (water resources), wind and solar resources. A retrospective analysis of both total and individual production and consumption of electricity in the period 1990-2023 concluded that a 47.5% increase in individual consumption was caused by the catastrophic population decrease in Georgia during the same period. The article also mentions that the average consumption of electricity in Georgia is half of the corresponding indicator of Germany, the USA - Mesa-Med, and Norway - one-sixth. The electricity balance of Georgia is negative. A significant part of electricity is imported from Russia and Azerbaijan. Among the problems faced by the electrical energy system, the article discusses the possibility of causing danger by depending on external sources of electricity, giving preference to the construction of large hydroelectric power plants (the construction of which destroys wild nature) and less attention to the study of the issue of regional production and consumption of electricity. The article provides conceptual solutions to each of these problems. Keywords: electric energy; hydropower; wind and solar energy; large and small hydropower plants; Electrical energy balance.

Development of modular polymeric nanoparticles for drug delivery using amine reactive chemistry.

Curcumin has been explored for its anti-cancer potential, but is severely limited by its hydrophobicity and sensitivity to light and water. In this study, poly (lactic-co-glycolic) acid (PLGA) nanoparticles (NPs) were synthesized to encapsulate curcumin via single emulsion method to improve curcumin stability and bioavailability. The PLGA NPs were coated with oligomeric chitosan (COS) and RGD peptide (a peptide consisting of Arg-Gly-Asp) using amine-reactive chemistry (NHS and EDC). Both COS and RGD had been previously shown to accumulate and target many different types of cancer cells. NPs were characterised based on size distribution, zeta potential, and binding efficiency of RGD peptide. They were also evaluated on encapsulation efficiency, and stability, of curcumin within the NPs. OVCAR-3 cancer cells were treated with COS and RGD-coated PLGA NPs loaded with Coumarin-6 dye for fluorescent imaging of cell uptake. They were also treated with curcumin-loaded NPs to determine cytotoxicity and effectiveness of delivery. The NPs exhibited size distribution and zeta potential within expected values, though binding efficiency of RGD was low. Curcumin-loaded NPs showed significant increase in cytotoxicity over free (unencapsulated) curcumin, and void (empty) NPs, suggesting successful delivery of curcumin as an anti-cancer agent; the performance of COS and RGD coated NPs over bare PLGA NPs was inconclusive, however, optimization will be required to improve formulation during the coating steps. This method of NP synthesis serves as proof of concept for a modular solution to the development of various coated polymeric NPs for other drugs or applications.

Analysis of Depreciation Methods Based on Cooperative Game Theory — Focusing on the Straight-Line Method

This study develops a model to explain why accounting procedures, also known as Generally Accepted Accounting Principles, are “generally accepted”. For this purpose, we focus on depreciation defined as the rational and systematic allocation of the original cost of an asset over the expected useful life of that asset. We investigate what it means to be “rational” using cooperative game theory. We show that cost allocations determined by the straight-line (SL) method, which is conventionally used worldwide, are elements of the core and that the conditions of the core can be rational in practice. Furthermore, we examine the relationship between the SL method and other solution concepts, such as the Shapley value and the nucleolus. Our next step is to clarify the characteristics besides the core selection of the SL method, those of other depreciation methods used in practice, and the logical relations between these characteristics.

Deep learning in high-frequency trading: Conceptual challenges and solutions for real-time fraud detection

High-frequency trading (HFT) has transformed financial markets by enabling rapid execution of trades, exploiting market inefficiencies, and optimizing trading strategies. However, this speed and complexity also present significant challenges for real-time fraud detection. Deep learning, a subset of machine learning, offers promising solutions to these challenges through its ability to analyze large volumes of data and uncover intricate patterns. This review explores the conceptual challenges and solutions associated with deploying deep learning for fraud detection in HFT environments. One of the primary challenges in implementing deep learning for HFT fraud detection is the sheer volume and velocity of data. HFT systems generate vast amounts of transactional data in milliseconds, necessitating highly efficient and scalable deep learning models. Convolutional neural networks (CNNs) and recurrent neural networks (RNNs) are particularly suited for this task due to their ability to process and analyze sequential data efficiently. However, these models require substantial computational resources and sophisticated infrastructure to operate in real time. Another significant challenge is the need for high accuracy and low latency in fraud detection. False positives can lead to unnecessary interventions, while false negatives can result in undetected fraudulent activities. Deep learning models must be fine-tuned to balance these risks, employing techniques such as hyperparameter optimization and ensemble learning to enhance their predictive capabilities. Additionally, integrating real-time anomaly detection methods can help identify suspicious activities promptly, reducing the window of opportunity for fraudsters. Data quality and integrity also pose substantial challenges. HFT environments are susceptible to noise and outliers, which can distort model predictions. Ensuring high-quality data through rigorous preprocessing and anomaly filtering is crucial for the accuracy of deep learning models. Techniques such as data augmentation and normalization can further improve model robustness. To address these challenges, a hybrid approach combining deep learning with traditional statistical methods and rule-based systems can be effective. This approach leverages the strengths of each method, providing a comprehensive fraud detection framework that is both accurate and responsive. Additionally, ongoing model retraining and adaptation to evolving fraud patterns are essential to maintain the effectiveness of the system. In conclusion, while deep learning presents significant opportunities for enhancing real-time fraud detection in high-frequency trading, it also requires addressing challenges related to data volume, computational demands, accuracy, and data quality. By employing a hybrid approach and continually refining models, financial institutions can effectively mitigate fraud risks and safeguard their trading operations.

Envy-freeness in 3D hedonic games

We study the problem of fairly partitioning a set of agents into coalitions based on the agents’ additively separable preferences, which can also be viewed as a hedonic game. We study three successively weaker solution concepts, related to envy, weakly justified envy, and justified envy. In a model in which coalitions may have any size, trivial solutions exist for these concepts, which provides a strong motivation for placing restrictions on coalition size. In this paper, we require feasible coalitions to have size three. We study the existence of partitions that are envy-free, weakly justified envy-free, and justified envy-free, and the computational complexity of finding such partitions, if they exist. We impose various restrictions on the agents’ preferences and present a complete complexity classification in terms of these restrictions.

Specific application of nature-based solutions in ecological restoration

As a result of the growing human capacity to exploit and the rising and demand for natural resources, the earth is now experiencing ecological overload.Ecological restoration has emerged as a significant concern that human beings must confront. The notion of Nature-based Solutions introduced by the International Union for Conservation of Nature (IUCN) in 2004 has garnered increasing scholarly interest in recent years . As to the IUCN, nature-based solutions refer to measures that safeguard, responsibly oversee, and rehabilitate both natural and modified ecosystems. Since the concept of nature-based solution was put forward, numerous scholars have made various attempts to use it in the field of ecological restoration. Through the method of literature review, this paper elucidates the basic principles of ecological restoration and nature-based solutions. This research studies the specific implementation of nature-based solutions in ecological restoration, focusing on their specific application in water body and land restoration. Additionally, this paper summarizes the advancements made in this field of research and provides illustrative examples of nature-based solutions applied in ecological restoration.

A Proof of Concept Using BLE to Optimize Patients Turnaround Time (PTAT) in Health Care

In 2022, Malaysia's Ministry of Health (MOH) acknowledged that government hospitals continue to face challenges in delivering high-quality patient care. A significant issue is the absence of a Real-Time Patient Location Monitoring and Tracking Solution, which prevents doctors from efficiently tracking patients within medical facilities. This lack of real-time tracking contributes to a decline in service quality, creating an urgent need for optimization in patient monitoring and tracking solutions. Implementing an effective tracking system can significantly enhance patient care quality, improve resource utilization management, and boost staff productivity, ultimately saving costs, time, and resources for hospitals. One critical area for improvement is the Patient Turnaround Time (PTAT), which refers to the duration a patient spends being processed at a hospital before being discharged. PTAT is currently prolonged in many hospitals due to the complex processes involved and patients becoming untraceable while waiting for their turn. To address these challenges, we have developed an Internet of Things (IoT) solution utilizing Bluetooth Low Energy (BLE) technology to optimize PTAT. This solution enables hospital staff to track patient movements and localize them in real-time. By using wearable devices, the system measures the distance from patients to various Access Points (AP) spread throughout the hospital based on the dBm value. This paper presents comprehensive experimentation for the Proof of Concept (POC) and pilot testing of this BLE-based solution. The results demonstrate the accuracy of using the Received Signal Strength Indicator (RSSI) to optimize patient turnaround times in hospitals. By implementing this BLE solution, hospitals can reduce the time patients spend waiting for treatment, thereby improving overall patient satisfaction and hospital efficiency. The ability to monitor patient locations in real-time will ensure that patients receive timely care, reducing the likelihood of them wandering off and becoming untraceable. This technology represents a significant step forward in modernizing patient care and streamlining hospital operations in Malaysia.

Nusyuz and Domestic Violence in the Perspective of Islamic Law and Positive Law

Nusyuz, which is textually understood as a wife who does not obey her husband, does not permit her husband when she wants to leave the house and the permissibility of husbands hitting their wives, which is considered legal by the Qur'an as stated in Q.S. An-Nisa: verse 34, improper interpretation, it leads to physical and psychological violence in the household and leads to disharmony and even triggers divorce. All forms of violence against spouses are not legalized in either the positive legal value system or Islamic law. The purpose of this research is to discover how the concept of nusyuz and alternative solutions to nusyuz are allowed and their handling from the perspective of Islamic law and positive law. This research uses a library research method (normative law), and uses a descriptive analytical research type, and the research results are analyzed qualitatively, by examining existing regulations. Both women and men can commit Nusyuz, a husband can be said to have committed nusyuz if he relinquishes his responsibility towards his wife. Beatings carried out by husbands against nusyuz wives based on surah An Nisa 34, are not freely legalized but only to awaken and return the wife to obedience, not blows that cause pain and even injure. Positive Law contained in Law No. 23 of 2004 concerning Elimination of Domestic Violence is very firm in not allowing beatings and eliminating domestic violence and even criminal sanctions for perpetrators, both husband and wife.

Aligning technical and project management through participatory approaches: An industrial case study

AbstractThe importance of managing complexity in innovation has been highlighted both in research and practice, however the question remains: how can this be accomplished? Although there have been answers to this question, the practical alignment of process (project management) and system (technical management) viewpoints remains understudied. We responded to this challenge with an in‐depth case study in high‐tech industry. In this paper we applied Human Centered Design (HCD) and Action Research (AR) principles in a novel context, namely systems engineering. We identified main barriers and key players, essential information elements, and solution requirements. Using co‐design, we iteratively generated solution concepts, out of which we selected and evaluated one candidate concept. We highlight two main areas in our results: 1) how participatory approaches can support solving systems engineering challenges in practice; and 2) how to align the process and system viewpoints. For the first, we discuss the implications, considering aspects like the time and effort investment, along with the benefits of ownership, empathy, democracy, and collective learning. Our insights show potential to further build on the application of participatory approaches in systems engineering to match existing solutions to the practice. For the latter one, we reflect on issues such as information overload, human aspects, and the new relationship between project managers and systems engineers. Considering the current complexity demands, it is crucial to establish a better alignment between these roles and between process and system viewpoints, as they cannot be left undefined and unsupported any longer.

Collaborative Effect-Centered Problem-Solving

Abstract To justify the individuality of design as a discipline, researchers repeatedly separated it from other disciplines while underscoring the integration of design in those disciplines. We resolve this apparent paradox by recognizing that people have knowledge, abilities, and tasks that can be attributed to several disciplines. We emphasize a collaborative effect-centered understanding and execution of problem-solving rather than an individual and design-centered one to enable each person to perform to the best of their abilities. Therefore, we introduce the newly developed “effect method,” which, by researching defined interrelations between subjects (terms considered as single entities) and systems (terms considered as multipart entities), empowers people to identify and understand relevant problems and solution approaches. The interrelations are defined by effects to be prevented (problem) or achieved (solution). Based on this, the effect method enables the development of system-compatible solution concepts. As a result, each person's creativity, knowledge, and best abilities can contribute to the collaborative development of relevant solutions.

MECHANISED COAL EXPLOITATION IN THE "BREZJE" PIT OF THE "DJURDJEVIK" BROWN COAL MINE

In addition to the coal and electricity market and changing geopolitical circumstances, there are other sufficiently rational reasons for opening new underground mining facilities and modernizing existing mining methods.Significant limiting factors and influences, in complex mining-geological conditions, most significantly affect the possibilities of the mechanized way of mining brown coal. The "Brezje" pit is a part of the deposit where the mining-geological factors are complex and determined by the natural conditions of the deposit's genesis. Excavation methods and technologies in complex deposit conditions must be based on great flexibility and adaptability.The complexity of the tectonic structure in the "Đurđevik" pit justified the application of chamber excavation methods with borehole blasting, in various technical modifications and solutions. In all previous solutions, the degree of mechanization of the method was not significantly improved and all modifications of the chamber method were non-mechanized or semi- mechanized with a large participation of manual work, technology based on drilling and blasting, high risk of injuries, low utilization of deposits, unjustified economic effects of work. The aim of this paper is to give an adequate answer to the hypothesis "in the block structure of the deposit with pronounced tectonics, it is possible to reduce the unfavorable influence of the complex mining-geological factors of the deposit on the excavation method by choosing modern mechanization for underground exploitation". The mechanized chamber method of excavation is a conceptual solution for the possible application in complex conditions of the proposed flexible mechanization for work in the "Brezje" pit. The advantage of modern multifunctional mining machines is a high degree of adaptability to the elements of the coal layer with the use of different working mechanisms (tools) that can be changed in a very short time depending on the working phase of the process. Key words: Pit, complexity, factors, chamber method, flexible, multifunctional machine

Formation of conceptual representations of reality on the basis of reflective practice (research experience)

Introduction. The transition from ordinary perceptions of reality to conceptualized ones is a significant problem of philosophical education. The aim of this article is to identify the ways of this transition in the course of doctoral students' work with modern philosophical literature, to substantiate ontological and epistemological principles of understanding reality, and to summarize modern approaches to solving this problem. Materials and Methods. On the basis of teaching practice, which goes back to Socrates' Maieutic method, the principle of “pro et contra”, and substantially determined by the discussions of realists and anti-realists about the nature of reality, the ways of strengthening the discipline of judgment, improving the reflexive culture, clarifying the bases of one's own ideas about the world and formalizing them in a thoughtful system of judgments are revealed. The method of research into the formation of conceptual representations of reality involves analyzing the ways of transition from unconsidered opinions through the recognition of their insufficiency and unsatisfactoriness to such knowledge, which Plato called ‘theory’ (θεωρία), i.e. rationally constructed principles of analytics. In this methodological approach (communicative-competence - in the modern formulation), the very sequence of cognitive acts is important: from ordinary ‘naïve’ perceptions - to a clear understanding of the complexity of the problem - then to the formation of questions in the audience that lead beyond a surface view of reality - and to the possible conceptual coherence and validity of perceptions of reality. Results. In the course of History and Philosophy of Science for doctoral students, the author proposed and justified the use of a three-level construct of moving from everyday representations of reality to conceptually meaningful ones. At the first level it was proposed to give an intuitive definition of the concept of ‘reality’; at the second level to analyze it, relying on sources from among those recommended by the lecturer or chosen independently, then briefly formulate the essence of realistic and anti-realistic approaches and identify the logic of one of them, and at the third level to move to the opposite position and present the relevant arguments. The author summarized the results of this procedure, which includes critical overcoming of ordinary statements about the nature of reality and dialogue between opposite conceptual solutions to the problem, and substantiated that such practice gives the effect of “awakened consciousness” and becomes the basis for readiness to conduct an internal dialogue on complex philosophical problems. Conclusions. The skills of reality analysis presented in the article develop and improve the reflexive practice of young researchers, clarify the basis of their own perceptions of the world, formalize them in a reasoned and critically elaborated system of judgments, and form their readiness to solve complex problems in science and philosophy.

Distributed sequential optimal power flow under uncertainty in power distribution systems: A data-driven approach

Modern distribution systems with high penetration of distributed energy resources face multiple sources of uncertainty. This transforms the traditional Optimal Power Flow problem into a problem of sequential decision-making under uncertainty. In this framework, the solution concept takes the form of a policy, i.e., a method of making dispatch decisions when presented with a real-time system state. Reasoning over the future uncertainty realization and the optimal online dispatch decisions is especially challenging when the number of resources increases and only a small dataset is available for the system’s random variables. In this paper, we present a data-driven distributed policy for making dispatch decisions online and under uncertainty. The policy is assisted by a Graph Neural Network but is constructed in such a way that the resulting dispatch is guaranteed to satisfy the system’s constraints. The proposed policy is experimentally shown to achieve a performance close to the optimal-in-hindsight solution, significantly outperforming state-of-the-art policies based on stochastic programming and plain machine-learning approaches.

Comfort, convenience and long-term effectiveness. Neighborhood in Ottawa, Canada

The article raises the issue of finding ways to restore and rebuild housing in Ukraine that was destroyed during Russia's full-scale invasion. The experience of housing construction in the second half of the twentieth century in Ukraine indicates significant miscalculations that were made. One of them is the use of monotonous, overly typified urban planning and functional planning techniques that did not take into account the temporal dynamics of the socio-demographic characteristics of the urban community, its stratification by age, family relations, life rhythms, interests, opportunities, etc. At about the same time, other housing was being built in North American cities, which has not lost its relevance to this day, and the organizational and architectural approaches used have proven to be appropriate and effective in long-term use. A detailed analysis of one of the residential districts in Ottawa, Canada, was carried out. Its urban planning, functional planning, and three-dimensional spatial solutions are considered. It was found that the key to the viability and efficiency of this urban formation was, firstly, the existence of a close relationship between the regulatory, socio-economic, territorial and urban planning and other components of the project; secondly, the interest of the construction company in the long-term economic stability of this residential area. The result of this approach was the ability to adapt to new rules and regulations, lifestyles, property status, and ideas about the comfortable stay of people who use this housing. It has been found that a variety of urban planning, architectural and spatial, typological and planning techniques, a change in the number of storeys of buildings, a developed intra-quarter and adjacent infrastructure, landscaping and greening of the territory are prerequisites for creating a quality living environment. The heterogeneity of the urban community brings the need to revise the established urban planning and typological techniques adopted in the Soviet era to the design of housing. It requires a wider application of non-traditional approaches, the involvement of positive foreign experience in the formation of conceptual solutions for residential development, which will allow to more fully meet the needs of residents, in accordance with their capabilities, tastes and preferences in the reconstruction of Ukrainian cities.

ANTIN RUDNYTSKY'S OPERA "ANNA YAROSLAVNA — QUEEN OF FRANCE": COMPARATIVE ANALYSIS OF THE AMERICAN AND UKRAINIAN FORMATS OF PRODUCTION

The author devotes this research to the phenomenon of the creation by Antin Rudnytskyi's the opera "Anna Yaroslavna — Queen of France", having used historiographical and iconographical sources, its artistic productions in American and Ukrainian formats. The relevance and necessity of taking into account the historical national theme in general and the opera in particular in today's socio-cultural realities are outlined. The role and place of the Ukrainian diaspora in the preservation of national identification of cultural property and artistic heritage in the conditions of stay in different countries of the world is clarified. Attention is focused on returning to the treasury of national musical culture and unjustifiably forgotten names and works of Ukrainian emigrant artists, one of their bright representatives is rightfully considered the American composer of Galician origin Antin Rudnytskyi. The literary background of the opera is analyzed and systematized being based on the peculiarities of the historical, sociocultural development of Kyivan Rus and France at the end of the early Middle Ages; the prerequisites for creating an opera are outlined, emphasizing the main storylines in the development of its dramaturgy; the author studied memoirs, reviews and publications on its production in American and Ukrainian formats. The article describes the differences in living conditions, the way of existence of Kyivan Rus and France during the specified era, emphasizing the peculiarities of their contemporary culture, lifestyle, and traditions. Attention is drawn to the choice of the effective vector of Yaroslav the Wise's activity in politics, diplomacy, interstate family ties with the leading royal courts of Europe, which contributed to the highest development of Kyivan Rus at that time, strengthening the princely secular power. On the contrary, the author emphasized the modest position of medieval fragmented France in the geopolitical development of Europe with the subordination of secular royal power to the Pope. The motivation of Antin Rudnytskyi's appeal to historical themes and the prerequisites for writing the opera "Anna Yaroslavna - Queen of France" as a "heartfelt confession" of the emigrant Maestro is determined. Two storylines in opera drama are analyzed — social-historical and domestic-psychological, with arguments for their conceptual solution. The reasons for the concertstage format of the implementation of the opera by the forces of the Ukrainian diaspora in America and the impossibility of its further stage life in the country are clarified. The conceptual production of the work in the National Opera of Ukraine in the stage format, the reasons for the shortcomings of its mise-en-scène development in connection with errors in the director's analysis and the creative idea of the performance are studied. The necessity of a thorough approach to the interpretation of historical operas of national themes with the use of large-scale monumental mass scenes is proven. Prospects for further scientific research on the given topic in the conditions of modern possibilities of musical theater and achievements of director's opera practice are predicted

Solid solution of zirconium on the M-site in Ti2AlC MAX phase coatings: Synthesis, structure and mechanical properties

Ti2AlC MAX phase is considered an ideal candidate for surface protective coatings in harsh environments due to its excellent resistance to oxidation and corrosion, yet poor mechanical properties are a key bottleneck for practical applications. In this work, taking the conception of solid solution, high-purity and high-hardness (Ti, Zr)2AlC coatings were synthesized on Ti-6Al-4V substrates using a multiple-target magnetron sputtering technique combined with subsequent annealing. The as-deposited Ti-Zr-Al-C coating was partially crystalline containing TiAlx phase, and MAX phases formed after annealing at 750 °C for 90 min. Comprehensive X-ray diffraction and high-resolution TEM analysis identified the formation of solid solution (Ti0.9Zr0.1)2AlC. The incorporation of Zr reduced the surface roughness and grain size of the coatings due to the increased nucleation sites and the suppressed atomic diffusion. Comparing with pristine Ti2AlC coating, the hardness of the (Ti0.9Zr0.1)2AlC coating was enhanced by 30 % from 12.8 GPa to 16.6 GPa. This enhancement can be ascribed to the synergistic strengthening from solid solution and grain refinement. However, fracture toughness slightly deteriorated in the (Ti0.9Zr0.1)2AlC coating due to the preferential crack path along the refined-grain boundaries.

Exponential stability of non-instantaneous impulsive second-order fractional neutral stochastic differential equations with state-dependent delay

The aim of this manuscript mainly concerned with a new class of exponential stability for non-instantaneous impulsive second-order fractional neutral stochastic differential equations (NIIFNSDEs) with state-dependent delay driven by Poisson jump in a separable Hilbert spaces. Firstly, a more appropriate concept of mild solution is introduced. Secondly, sufficient conditions are derived for the existence of mild solution by means stochastic analysis, fractional calculus approach and Mönch fixed point theorem with appropriate hypotheses on non-linear continuous functions combined with solution operator. Finally, stability results are derived based on the pth moment exponential stable with the help of new impulsive integral inequality techniques. In addition, an example is provided to validate the theoretical results. This manuscript is the unique combination of the new theoretical investigation which is simulated numerically. Our work extends the works of Arthi et al. (2014), Das et al. (2016), Huang et al. (2018), Pandey et al. (2014), Wang et al. (2018), Yan and Jia (2016).

The automation of the processes of students’ reporting documentation standard control: The software solution concept

Reporting documentation is one of the assessment tools used to verify the students’ mastery of several universal, general professional, and vocational competencies, reflecting the ability to search, critically analyze, and synthesize information, as well as the ability to design methodological materials and develop technical documents related to professional activities. Mastering the relevant competencies can be assessed by the results of analyzing the report text and controlling the compliance of documents with requirements to the design, accompanied by a set of standard checks. Such standard control does not imply any variability in the assessment and therefore has prospects for automation. The introduction of a software solution aimed at automating the processes of standard control will reduce the time spent on checking the reporting documentation and the formation of recommendations for students to correct the detected inconsistencies.The article analyzes the most common errors in the design of students’ reporting documentation on the results of internships, compiles a classification of errors, and suggests methods for detecting each type of non-compliance with the requirements to the design of documents. The concept of the software solution for automation of standard reporting documentation control, which offers a realization of the proposed methods and creates interfaces for interaction with users, is created using the principle of modularity. The results of the research presented in the article demonstrate the potential of applying automation methods to the tasks of checking students’ reporting documents.
