An Assessment of Geological Hazard Management using Dynamically Stabilized Recurrent Neural Network and Beluga Whale Optimization Algorithm
Authors: Chenqi Xie
Published: May 2024

Mountainous region geological hazards are a leading cause of natural disasters, resulting in significant human and economic losses. Regional topography, landforms, lithology, plant life, geological circumstances, and meteorology all have a significant impact on their creation. Gansu, situated in the interior of Northwestern China, features Lanzhou as its capital and primary urban center, positioned in the southeast of the province. Geological risks, particularly landslides, mudslides, and avalanches, present significant challenges to Gansu Province. Consequently, local authorities are actively devising customized strategies to mitigate these hazards and foster sustainable development. In this research work, an Assessment of Geological Hazard Management using Dynamically Stabilized Recurrent Neural Network and Beluga Whale Optimization Algorithm (AGL-HM-DSRNN-BWOA) is proposed. Initially, the input raster data are gathered from the Normalised Difference Vegetation Index (NDVI) dataset. The input raster data is then pre-processed using Adaptive Actor-Critic Bilateral Filter (A2CBF) to reduce noises and increase the overall quality of the raster data. To classify the geological hazards, the pre-processed raster data are fed into a neural network named DSRNN. The geological hazard is accurately categorized as low risk, medium-low risk, medium-high risk, high risk using proposed DSRNN. In general, DSRNN does not express some adaption of optimization strategies for determining optimal parameters to promise exact classification for managing geological hazard by assessment. Therefore, Beluga Whale Optimization Algorithm (BWOA) is proposed to enhance weight parameter of DSRNN classifier, which precisely assess for managing the geological hazards. The efficiency of the proposed AGL-HM-DSRNN-BWOA approach is evaluated using a number of performance criteria, including accuracy, sensitivity, specificity, ROC, mean square error, root mean square error, mean absolute error. The proposed AGL-HM-DSRNN-BWOA method attains 22.36%, 25.42% and 18.17% higher accuracy, 21.26%, 15.42% and 19.27% higher sensitivity, 28.36%, 25.32% and 28.27% higher F-measure compared with existing methods, such as the Risk assessment and its influencing factors examination of geological hazards in typical mountain environment (RA-IFA-GH-TME), Feasibility study of land cover categorization under normalized difference vegetation index for landslide risk assessment(LCC-NDVI-LRA), and Multiple hazard exposure mapping under machine learning for Salzburg, Austria (MH-EM-SSA-ML) respectively.

Frequency Offset Estimation for UWB-OFDM System using Weight and Exhaustiveness based Monarch Butterfly Optimization Approach
Authors: Eswaramoorthi R
Published: May 2024

The performance of an OFDM system has limitation because the carrier frequency offset (CFO) and sampling frequency offset (SFO) is not estimated correctly. Current methods propose the way of obtaining frequency estimation by using the evolutionary algorithm, but the evolution algorithm suffers from the premature convergence problem. In order to provide efficient frequency offset estimation, this paper proposed weight and exhaustiveness based monarch butterfly optimization approach. First, on the transmitter block, for modulating an input symbol, the Hybrid-Quadrature Phase-Shift Keying modulation scheme is used. Brunn’s IFFT is done at each transmitter for symbol mapping and then in each transmitter block cyclic prefix is inserted. After that, WE-MBO algorithm estimates the frequency offset. On receiver side, the inverse operation of the transmitter is performed. After comparison of proposed system with the existing system, the proposed system gave better performance.
Design of an Iterative Method for Optimizing Solar Power Systems using Quad LSTM with IoT Integration Operations
Authors: Swapna Choudhary
Published: May 2024

The growing necessity for sustainable energy solutions underscores the critical need for optimizing solar power systems. Existing methodologies predominantly focus on static strategies with limited adaptability to dynamic environmental and operational conditions, often resulting in suboptimal performance and inefficiency. This research introduces a comprehensive, integrated framework employing Internet of Things (IoT) technologies alongside advanced machine learning and deep learning methodologies to enhance solar power system efficiency and reliability levels. The proposed model integrates four key components: predictive maintenance using Support Vector Machines (SVM) for enhanced anomaly detection, solar power forecasting via Quad Long Short-Term Memory (QLSTM) neural networks, dynamic load balancing through Reinforcement Learning with Deep Q-learning, and the integration with smart grids employing Decentralized Multi-Agent Systems (MAS) with Auction-Based Mechanisms. Each method is selected based on its suitability to address specific challenges within the solar power domain: SVMs for their effectiveness in high-dimensional anomaly detection, QLSTMs for their superior temporal pattern recognition in forecasting, Deep Q-learning for its adaptability in dynamic load management, and MAS for efficient decentralized energy resource coordination operations. The implementation of these methodologies demonstrates significant advancements over traditional approaches. Predictive maintenance facilitated by SVMs leads to a 20% reduction in maintenance costs, while QLSTM-based forecasting achieves a 95% accuracy rate, thereby enhancing grid management and reducing revenue losses. Moreover, reinforcement learning optimizes energy utilization, decreasing wastage and system downtime by 10% and 5% respectively. Lastly, the MAS framework promotes a 20% increase in energy trading efficiency, yielding a 10% reduction in transaction costs and bolstering grid resilience levels. This work represents a significant leap forward in solar power optimization, offering a scalable, efficient, and intelligent framework that paves the way for more sustainable and reliable energy systems. The integration of IoT with machine learning and deep learning presents a paradigm shift in renewable energy management, marking a critical step toward achieving global sustainability objectives..

Deep Learning for Arabic Speech Recognition Using Convolutional Neural Networks
Authors: Soufiyan Ouali
Published: May 2024

Extracting the speaker's emotional state from their speech has become an active research topic lately due to the demand for more human interactive applications. This field of research has noted significant advancement, especially in the English language, owing to the availability of massive speech-labeled corpora. However, the progress of analogous methodologies in the Arabic language is still in its infancy stages. In this paper, we present a Speech Recognition model for the Arabic language, proficient in discerning both the emotional state and gender of the speaker through voice analysis. Three primary emotion labels were selected: low, standard, and high levels of emotion. Various spectral features, such as the mel-frequency cepstral coefficient (MFCC), were extracted and tested to determine the optimal features. Furthermore, various Machine Learning models (SVM, KNN, and HMM) and Deep Learning models (LSTM and CNN) were evaluated for training. The results were compared between the five models using different extracted features, ultimately culminating in the selection of MFCC, root-mean-square (RMS), mel-scaled spectrogram, spectral, and zero-crossing rate as spectral features, and the CNN as a classification model. This selection yielded significant results, with an accuracy of 93% for emotion recognition and 99% for gender recognition.

Miért (nem) pályaelhagyók a(z agrár)kutatók?
Authors: Szabó Anett Krisztina
Published: May 2024

Jelen tanulmány célja a kutatók pályaelhagyásával kapcsolatos ismereteink bővítése a következő kérdések megválaszolása mentén: Melyek azok a szegmensek, ahol a kutatók leginkább a kutatói életpálya elhagyását tervezik? Melyek azok a tényezők, amelyek a pályaelhagyást elősegítik vagy éppen gátolják? 117 kutató válaszát vizsgáltam 2022 telén primer standardizált kérdőíves felmérés során, melynek eredményeként látható, hogy a 45 év alattiak, az agrár- és biológiai tudományok képviselői és a nők gondolkoznak leginkább a pályaelhagyáson. A kérdőíves felmérés alapján megerősíthető, hogy a személyes anyagi nehézségek azok, amelyek leginkább eltántorító tényezőként hatnak a kutatókra. Az agrár- és biológiai tudományok képviselői ezen kívül még a kutatási források hiányát és az igazságtalan rendszert jelölték meg okként. Ezen három égető probléma mellett további 8 tényezőt emeltek ki a kutatók, melyek közepesen erős hatással bírnak pályaelhagyási szándékukra. A pályaelhagyást támogató tényezők segítségével meghatározható mind az agrár- és biológiai tudományok képviselőinek, mind pedig a válaszadók pályaelhagyási potenciálját leíró egyenese. A kutatók mellett, standardizált mélyinterjú keretében 3-3 agrárkutatás orientáltságú felsőoktatási intézmény és kutatóintézet összesen 7 vezetőjének tapasztalatát és véleményét tártuk fel a témában. A vezetők is a pénzügyi eredetű okokat jelölték meg elsődlegesnek, emellett még a tapasztalatszerzést és a szakpolitikai feladatok iránti igényt határozták meg a pályaelhagyási szándék fő okaiként. A vezetők kitértek arra is, hogy szerintük a sok negatív tényező mellett miért maradnak a kutatók így is a pályán. Bár a vezetők számára is egyértelmű, hogy rendkívül rögös úton kell a pályakezdő kutatónak végighaladnia, azonban az előrehaladási lehetőség, a pályázati lehetőségek, a nemzetköziesedés, az intézeti légkör és a regionalitás mégis a pályán tartja a legtöbb kutatót.

Published: May 2024

Exploring variation in community structure and species diversity across spatial scales provides insights into factors structuring communities and promoting diversity and informs management and conservation. This study focused on spatial variation in fish community structure and diversity in the nearshore benthoscapes of San Salvador, The Bahamas. Data were collected at thirteen sites across five regions and three different habitat types (patch reefs, high relief, and rubble sites) using video and roving snorkeler observations, which were analyzed separately. Although there were similar sets of dominant species around the island, multivariate analyses indicated significant differences in community structure among regions and sites and at the within-site scale, which can be attributed to differences among habitat types and localized environmental effects at the site level. A total of 55 species were found in the video data; 141 species were found in the snorkeler observations, likely due to the presence of a greater variety of habitats (deeper patch reefs, seagrass beds, and mangroves), larger area observed, and increased likelihood to observe cryptic species. Diversity partitioning indicated that β2 (among sites within a region) and β3 (among different regions) diversity contributed greater than expected numbers of species to overall ??-diversity. The different regions around the island and the mix of habitats within each region may provide some measure of resilience in fish communities to disturbances and changing environmental conditions. Our results underscore the importance of protecting mixes of habitat in conservation and management efforts focused on the nearshore benthoscapes of tropical islands such as San Salvador.
Impact of Perceived Servicescape on Patient Satisfaction through Mediating Role of Service Credibility and Moderating Role of Received Word of Mouth in Rehabilitation
Authors: Zahid Tanzila
Published: May 2024

The aim of this study was to explore the effects of perceived servicescape (PS) and credibility of the healthcare service provider (CHSP) on patient satisfaction(PtS) in rehabilitation settings of  public and private hospitals of Islamabad and Rawalpindi, Pakistan. Mediating effect of CHSP and moderating effect of received word of mouth (WOM) have also been studied in this relationship. A sample of 300 patients receiving rehabilitation care was selected by applying convenience sampling technique. The design of this study was cross-sectional in nature. Self-administered questionnaire was designed to be utilized. Application of the correlation and regression were executed to analyze the collected quantitative data. The cross-sectional study method, limited geographical area coverage, and small sample size did not allow the detailed testing of the causal relations among study variables. Results of this study have indicated that there was a significant direct positive relationship between perceived servicescape and patient satisfaction and this relationship was also mediated positively by CHSP. There was a substantial direct positive relationship between perceived servicescape and CHSP and, between CHSP and patient satisfaction. However, the moderating effect of received WOM was found to be insignificant. It is recommended that healthcare managers should develop a credible service framework that focuses on better affordability, competitiveness, awareness, empathy, service expertise, pleasant interactions with patients through centeredness communication and beliefs and, subsequently, it will contribute to patient satisfaction and success of the rehabilitation settings. This is the first-ever study of the impact of perceived servicescape on patient satisfaction through CHSP as a mediator and the moderating influence of received WOM in rehabilitation.

Published: May 2024

Монокристаллический нитрид бора с кубической симметрией (c-BN) представляет собой сверхтвердый материал с широкой запрещенной зоной и со значительным потенциалом для применения при экстремальных температурах и давлениях. Тем не менее, его практическому использованию в технологии и материаловедении препятствуют две основные проблемы: (i) сложность производства высококачественных пленок c-BN и (ii) проблема эффективного n- и pлегирования его матрицы. Данное теоретическое исследование посвящено выяв-лению пределов растворимости кремния (Si) и углерода (C) в c-BN и нитриде бора типа вюрцит (WZ-BN) на основе приближения строго регулярного раствора. Эти элементы являются ключевыми кандидатами в качестве примесей n-типа в BN, что позволяет решить критическую проблему при реализации электроники на основе c-BN. Рассчитанные свободные энергии Гиббса бинарных смесей в интервале температур 800–3000 К указывают на то, что наличие нестабильных областей и, следовательно, областей несовместимости является преобладающей характеристикой этой системы. Анализ показывает, что на величину этих областей влияет не только температура, но и кристаллографическая структура. Результаты расчета предела растворимости Si в бинарной системе BN-Si хорошо согласуются с последними экспериментальными результатами. Представленные здесь результаты могут быть использованы при выращивании многокомпонентных объемных кристаллов, тонких эпитаксиальных пленок и наноструктур на основе твердых растворов BN-Si-C.
Cubic boron nitride (c-BN) is an ultrawide band gap, superhard material with significant potential for applications under extreme temperatures and pressures. Nevertheless, two major challenges hinder its practical utilization in technology: (i) the difficulty in producing high-quality c-BN films, and (ii) the challenge of effectively n- and p-doping its matrix. This theoretical study focuses on investigating the solubility limits of silicon (Si) and carbon (C) in the c-BN and wurtzite BN (WZ-BN) on the basis of the strictly regular solution approximation. These elements are key candidates as n-type dopants in BN, addressing a critical concern in the realization of c-BN based electronics. The calculated Gibbs free energies of binary mixtures within the temperature range of 800–3000 K indicate that the presence of unstable regions, and consequently, miscibility gaps, are a prevalent characteristic of this system. The analysis reveals that the immiscibility gap is influenced not only by temperature, but also by the crystallographic structure. The calculated results of Si solubility limit in BN-Si binary system are in a good agreement with the latest experimental results. The findings presented here are applicable to the fabrication of multicomponent bulk crystals, epitaxial thin films, and nanostructures based on BN-Si-C solid solutions.

Social work is characterised by uncertainty and ambiguity, social workers are mandated to intervene in the lives of families, requiring them to make morally charged, complex decisions with and for families. The field is beset by high workloads, time pressure, negative media attention, and cost-containment measures. In recent years, acknowledgement of the complexities of social work and the challenges faced by professionals has grown, prompting attempts to reorganise the field through frequent reforms, and to reduce uncertainty of practice through standards and accountability measures. Concurrently, there is a greater recognition of the importance of professional judgement, and the need for reflexive practice that engages different knowledges, to allow for more tailored care. The Dutch social care system is currently facing a crisis, and the government has implemented temporary programs to redesign standards and practices. These experimental spaces are the main research site of this thesis, which aims to explore how Dutch social care actors navigate the friction between reforms, standards, accountability, and professional autonomy in highly charged moral settings in social care. This thesis aims to explore how Dutch social care actors navigate the friction between reforms, standards, accountability, and professional autonomy in highly charged moral settings in social care. The research for this thesis was conducted in three studies in the Netherlands: a study on the use of intuition by youth care professionals and two action research studies focused on reform, discretionary space and accountability in social care and child protection. Ultimately, I argue that we need to treat the system similarly to families in need: when professionals look at families, they are expected to look at them as a complex network with a history, with values, different roles and complexities. Families are not expected to get it right immediately, but can work in incremental changes together with those in their network and care providers. However, when there is a crisis or the need for sudden, larger changes, there is space and authority to make these decisions. There is a collective responsibility, reflection and shared decision-making towards the shared aims. This means that the social care system requires engagement in continuous incremental, collective, reparative work that explores alternative notions of success and failure, and in line with that to reconsider underlying values and notions of accountability and governance, to build a system that fosters a space in which vulnerable families, professionals, managers and administrators can be supported.

The emerging trends towards intelligent computing have drastically changed the human lifestyle in every facet of their lives. Due to the swift escalation of smart systems and emerging technologies, human life has become much more dependent and even more addicted to fulfilling their desire using smart and tiny resource-bounded gadgets. This revolution has evolved towards autonomous decision support systems. Autonomous decision support systems have the ability to acquire information autonomously, reason the information, and adapt behavior accordingly. As these systems are deployed in a highly decentralized environment and exhibit complex adaptive behavior, however, the inconsistent nature of information may raise different challenging issues. This paper presents a multi-agent environmentally-aware framework for modeling and reasoning flight management systems. This system has a sound reasoning mechanism to execute and monitor flight control activities while considering liveness and safety-critical constraints. We use the UPPAAL model checker to formally analyze the system’s behavior and verify correctness properties.

O presente trabalho objetiva estudar a relação estrutura e dureza de ligas de alumínio dos sistemas Al-CuNi e Al-Ni obtidas por solidificação unidirecional ascendente. Foram fabricados quatros lingotes dos sistemas Al-Cu-Ni e Al-Ni solidificados em um dispositivo de solidificação transiente unidirecional ascendente com controlador de temperatura, que possui uma lingoteira de aço e resistência elétrica isolada com material refratário em sua volta, permitindo um ambiente propício à extração de calor em uma única direção.Foram realizadas análises de metalográficas das ligas obtendo as macro e microestrutura, medindos os espaçamentos dendríticos secundários (λ2) e Microscopia Eletrônica de Varredura (MEV). Os resultados metalográficos apresentaram estruturas predominantemente colunares e microestruturas dendríticas, que são influenciadas diretamente pelo fator taxa de resfriamento na medida que o esfriamento se propaga.  Os valores de espaçamentos dendríticos secundários (λ2) foram menores nas regiões próximas da extração de calor com valor médio de 7,86 µm para a região R1 da liga Al-2,5%Ni enquanto nas ligas Al-4%Ni e Al-9%Ni essa mesma região apresentou valores médios de 5,89 µm e 4,81 µm, respectivamente. Nas regiões mais próximas da base do lingote, a estrtuta mostrou-se mais refinamento para todas as ligas estudadas neste artigo. Esse comportamento deu-se porque as taxas de extração de calor são maiores  quando mais próximas da base que se extrai calor. Além disso, foi observado a diminuição da dureza nas regiões mais afastadas da interface, influenciada pelo aumento do espaçamento dendrítico. A resistência a dureza da liga do sistema ternário Al-Cu-Ni apresentou maior resistência quando comparada com a do sistema binário Al-Ni.

O conceito de alfabetização e letramento, por várias décadas ficaram excessivamente estáticos, não alterando suas definições. Com o surgimento de novas tecnologias estes conceitos estão se modificando, pois surgem a todo instante ferramentas digitais para auxiliar na alfabetização e letramento dos educandos. Salienta-se o quão importante está sendo a utilização destes instrumentos digitais, ao qual podem ser utilizados como ferramentas de inclusão social e, também, se torna uma maneira de democratizar o conhecimento. Nesta pesquisa irei esculpir o referido artigo com uma nova forma de ensino, baseada na inclusão digital.   Ainda, será demonstrada algumas distinções e harmonia entre alfabetização e letramento. Assim, será possível compreender como se trata a alfabetização e letramento contemporâneo e, ainda, será trabalhado o ensino a distância e o acesso as novas tecnologias aos estudantes.

Mục tiêu của nghiên cứu này là đánh giá tiềm năng trữ nước ngọt vùng Đồng Tháp Mười, tỉnh Đồng Tháp trong bối cảnh biến đổi khí hậu (BĐKH). Để đạt được mục tiêu trên, trước tiên, khu vực trữ nước tiềm năng được xác định từ bản đồ địa hình và cao trình mực nước cao nhất cuối mùa lũ theo từng tần suất; tương quan mực nước giữa các trạm được xác định, từ đó đánh giá tiềm năng trữ nước theo các kịch bản BĐKH giai đoạn 2030, 2040 và 2050; nhu cầu nước của các ngành dùng nước được ước tính và từ đó, khả năng bổ sung nguồn nước từ nguồn trữ nước đánh giá cho các tháng mùa khô năm tiếp theo.Kết quả nghiên cứu cho thấy, khu vực Tràm Chim cũng như vùng lân cận có tiềm năng trữ nước vào cuối mùa lũ, do điều kiện địa hình thấp và là khu vực bảo tồn sinh thái đất ngập nước. Kết quả ước tính nhu cầu nước cho vùng hạ lưu cho thấy nhu cầu nước cho nông nghiệp chiếm phần lớn (trồng trọt). Trong điều kiện BĐKH, tiềm năng trữ nước khu vực Tràm Chim và khu vực lân cận có thể bổ sung vào nguồn nước hiện có để đáp ứng phần nào các nhu cầu nước (chủ yếu là đảm bảo 100% cung cấp nước sinh hoạt và hoạt động công nghiệp). Cụ thể, đến năm 2030 trữ lượng này sẽ cung cấp nhu cầu nước bốn tháng mùa khô lần lượt là 19,53%; 19,54% và 19,54% tương ứng với các kịch bản RCP2.6, RCP4.5 và RCP8.5 (tần suất 3%). Kết quả nghiên cứu là cơ sở cho bước đầu cung cấp thêm cơ sở khoa học giúp người dân, các nhà hoạch định chính sách lẫn các cơ quan chức năng có sự nhìn nhận toàn diện và đưa ra các quyết định phù hợp cho toàn vùng trong bối cảnh BĐKH.

The European Union (EU) has deployed a wide variety of civilian missions that have sought to advise, train and build the capacity of internal security sectors in host coun­tries as part of its civilian Common Security and Defence Policy (CSDP). These mis­sions constitute integral parts of broader international programmes of Security Sector Reform (SSR) in conflict-affected countries. Their strategic objective is to con­tribute to the development of a civilian security sector that is efficient and accountable, and enjoys the trust of the public. This report looks at three case studies: EUPOL Afghanistan (2007–2016), EUCAP Sahel Mali (2014–) and EUCAP Sahel Niger (2012–2024). All three have engaged in civil­ian SSR activities amid ongoing armed conflict, and operated in broader national and international counterinsurgency contexts. Each case study reflects on the key research question: ‘What contributions have EU civilian CSDP missions involved in SSR made to durable peace?’
