Rapid advances in high fidelity modeling and high performance computing capabilities have enabled their routine utilization in support of aircraft design. Analysts are able to generate orders of magnitude more data that must then be turned into actionable intelligence to guide design. Enabling effective application of advanced analysis to design requires a robust end-to-end digital transformation to make the simulation processes reusable, repeatable, traceable, scalable and minimize setup errors. This is achieved through the development of a Computational Fluid Dynamic (CFD) modeling framework where streamlining and automation are inserted within the current CFD workflow that involves model setup, simulation and post processing. Workflow automation techniques have been implemented in simulation pre and post processing that reduce the overall process time or enhance the fidelity of the simulation. To conduct CFD evaluations through flight envelope efficiently, space filling methods that take into account uncertainties of complex systems are needed and have driven updates to the boundary condition and design of experiments (DOE) generation within the workflow. Vehicle sub-system design can be highly iterative, performed by a large number of participants in multidisciplinary groups. To ensure traceability across the digital thread, a provenance and metadata storage methodology has been implemented to capture information about CFD simulations and construct a query able database while a model-based systems engineering (MBSE) framework provides a structured and integrated approach to managing information throughout the product lifecycle. The SIM-FIX-SIM approach enabled with a robust analysis framework for digital flight assessment prior to first flight will contribute to the overall goal of reducing development timelines and achieving cost reduction goals for cutting-edge rotorcraft development programs.
Comparison between Gimballed and Hingeless Tiltrotor Whirl Flutter Stability with Multibody Dynamics Analyses
Authors:   The University of Alabama, Baggett Jennifer , Shen Jinwei
Published: September 2024

The tiltrotor whirl flutter stability of a gimballed hub and a hingeless hub are investigated using multibody dynamics simulations. A semi-span wind tunnel tiltrotor model are developed using the multibody dynamics code: Dymore. CAMRAD II predictions are used to correlate the Dymore predictions of the baseline tiltrotor characteristics. The rotor structural frequencies of the gimballed tiltrotor and the hingeless tiltrotor are compared between Dymore and CAMRAD II predictions with good agreements. CAMRAD II model of the baseline TRAST gimballed tiltrotor is used for correlating the whirl flutter stability with that of the Dymore model. Overall good agreements are shown for both the frequencies and damping ratios of all three wing modes. The effects of key design variables, such as blade stiffness, rotor RPM, and Δ3 on tiltrotor whirl flutter stability of both hubs are studied.
Scoping, Tailoring, and Abstraction Refinement in Hazard Assessment Processes
Authors:   NASA Langley, Graydon Mallory ,   Certification Services Inc., McCormick Frank , Neogi Natasha
Published: September 2024

Hazard assessment is an engineering activity that produces insight into which states of thing being engineered might be hazardous. In aviation contexts, it is often performed for certification credit at both the aircraft and system levels during the early design phase of the system's lifecycle. However, novel aircraft paradigms such as urban air mobility (UAM) operations might either violate assumptions on which traditional aviation hazard assessment is based or simply possess attributes that would make other approaches more effective. In this paper, we define the key concepts underpinning hazard assessment and identify the limitations and assumptions inherent in hazard analysis. We analyze popular techniques to show how they embody these key concepts. We identify ways in which hazard assessment may be scoped and tailored to an application. And, using worked examples, we discuss how, where, and why such tailoring might be needed, especially in novel contexts.

On April 19, 2021, Ingenuity became the first helicopter to fly on Mars at Jezero Crater, completing a total of 72 flights by the end of its mission. The success of Ingenuity resulted in various research efforts to further exploreMars via vertical flight, including two optimized Ingenuity-sized helicopters proposed to retrieve samples for the 2028 Mars Sample Return mission. To aid in the design process for the two proposed Sample Retrieval Helicopters, both heritage and optimized, increased diameter rotors were tested at the NASA Jet Propulsion Laboratory in the 25-ft Space Simulator. Three test campaigns were performed using the Ingenuity rotors and optimized Sample Retrieval Helicopter (SRH) rotors for several rotor speeds, densities, configurations, and collectives to identify performance limitations. These three test campaigns included the Ingenuity Engineering Design Model 1 (EDM-1) with and without a cruciform box, Transonic Rotor Test (TRT) rig, and SRH Dual Rotor Test (DRT). Experimental setup, test matrix, data processing, data quality, and performance results for EDM-1, TRT, and DRT campaigns are presented and discussed. Experimental results from the test campaigns will aid in future experimental methods and validation efforts for planetary rotorcraft exploration.
Evaluation of Local and Global Diagnostics for the Integration of Stochastic Time Series Models and Variational Autoencoders: Experimental Assessment on a Full Scale Helicopter Blade
Authors:   Rensselaer Polytechnic Institute, Fan Yiming , Zhou Peiyuan , Forrester David , Ju Brian , Kopsaftopoulos Fotis
Published: September 2024

In this work, a unified framework integrating global and local SHM methods for structural health monitoring (SHM) of rotorcraft structures is proposed. This framework integrates both "local" ultrasonic-guided wave-based and "global" vibration-based SHM schemes for tackling damage detection, identification, and quantification under uncertainty. The local SHM is completed by training a variation of variational auto-encoder (MMD-VAE) along with feed-forward neural networks (FFNN). The compressed latent space vector obtained during the training process is applied to achieve both signal reconstruction and state prediction. In terms of the global model, functionally pooled auto-regressive models with exogenous excitation (VFP-ARX) models are applied including to capture low-frequency vibrations. The complete experimental evaluation and assessment of the proposed framework are presented for an Airbus H125 helicopter blade under both low-frequency vibrations and ultrasonic guided waves for SHM.
Use of Machine Learning Techniques to Support Future Ship-Helicopter Operations Research; an Initial Investigation
Authors:   University of Liverpool, Newton-Young Daniel , White Mark , Green Peter
Published: September 2024

This paper reports on the initial implementation of Machine Learning (ML) for predicting the workload experienced by a pilot when performing a recovery to a naval ship. Pilots classify their workload for each landing by providing a subjective rating, which is used to determine the ship-helicopter operating limit (SHOL). Different workload metrics have been trialed to bridge the gap between pilot subjective ratings and objective flight data. With hundreds of different helicopter, ship and airwake parameters available to examine, ML provides an approach to understanding the complex interactions between these variables. This paper looks at the initial results obtained by applying ML techniques to train a classification algorithm with pilot control input data. Preliminary results showed 77.14% accuracy when training a Linear Discriminant algorithm to predict pilot workload from cyclic, collective, and pedal input data.

We appreciate the insightful comments provided by Josef Finsterer regarding our article on the first evidence on the effects of the Home Full-Body in-Bed Gym protocol as a potential intervention to mitigate age-related muscle loss based on the preliminary positive results of a Padua prospective observational study.1 We acknowledge the importance of the points raised and would like to address them in this response.
At the University of Padua, we conducted a study aimed at evaluating the impact of a home-based Full-Body in-Bed Gym protocol on various outcomes in elderly individuals, which was published in 2023.1 The rational of our proposal is based on the fact that functional muscle decay of aging is inevitable, but that the general population is highly hypoactive, let's say "lazy". The increase in daily muscular activity even through “Home In-Bed Gym” recovers at least in part the potential abilities progressively lost. Therefore, it is easy to rejuvenate the “lazy” population, that is, the vast majority of elderlies.[...]

Background: The epidemiology of cerebral palsy (CP) is poorly described in Ghana. These data are crucial for evidence-based intervention for children with CP in the country.Objectives: We aimed to describe the epidemiology of CP among children in Ghana.Method: We established the first institution-based register of children with CP in Ghana (Ghana CP Register–GCPR). Children with confirmed CP aged 18 years were registered following a detailed neurodevelopmental assessment. Socio-demographics, risk factors, predominant motor type and topography, gross motor function classification system (GMFCS), associated impairments, education and rehabilitation status were documented.Results: Between October 2018 and February 2020, 455 children were registered (mean [standard deviation {s.d.}] age at assessment: 5.9 [4.1] years). Preterm birth and low birthweight were reported in 52.0% and 21.1% children respectively. Most children (79.6%) had a pre- or perinatally acquired CP and the mean (s.d.) age of CP diagnosis was 22.2 (21.6) months. Overall, 55.9% of children had spastic tri- or quadriplegia, 60.5% had GMFCS level III–V and 70.3% had ≥ 1 associated impairment. However, 20.5% had never received rehabilitation services and 69.6% of school-aged children in the GCPR were not enrolled in schools.Conclusion: The study findings indicate a high burden of severe motor and associated impairment among children with CP in Ghana which highlights the need for tailored interventions to improve health and well-being of children with CP in the country.Contribution: The study highlights the need for interventions to improve functional outcome, health and well-being of children with CP in Ghana.

Authors: Du Plessis Jeanne , Temane Annie , Poggenpoel Marie
Published: September 2024

Background: Non-compliance with psychiatric medication among patients diagnosed with depression ranges from 28% to 52% exacerbating illness and reducing treatment effectiveness. There is a paucity of research on medication non-compliance and its causes in South Africa and globally, and an urgent need to develop appropriate interventions.Aim: This study aimed to explore and describe the experiences of adults living with depression who are non-compliant with their psychiatric medication and formulate recommendations to facilitate their medication compliance.Setting: The study was conducted in a psychiatric ward at a public hospital in Gauteng, South Africa.Methods: The study employed a qualitative, exploratory, descriptive and contextual research design. Ten adults’ lived experiences were explored using in-depth individual interviews, and Tech’s coding method was used to analyse data.Results: Two themes emerged from the data: adults living with major depression offered several reasons for non-compliance, and adults living with major depression experienced non-compliance, which created a setback to their recovery.Conclusion: Non-compliance with medication is a common challenge among adults receiving mental health care and treatment. Ensuring compliance to medication is crucial for improving the prognosis of psychiatric conditions. Therefore, it is essential for healthcare practitioners in the field of psychiatry to have a comprehensive understanding of medication compliance and to effectively address any challenges that may arise in this area.Contribution: This paper contributes to the research field and adds knowledge to clinical nursing practice by exploring adults’ experiences with non-compliance to psychiatric medications while living with depression in the South African context.
The spate of spousal homicide in Nigeria: Reconsidering the Christian divorce prohibition
Authors: Ademiluka Solomon O.
Published: September 2024

In recent times, spousal homicide resulting from domestic violence has been on the increase in Nigeria, and one major factor responsible for this is the Christian doctrine that prohibits divorce. Hence, employing the historical-critical exegesis and descriptive approach, this article postulated a correlation between this doctrine and spousal homicide, and sought a possible reconsideration of divorce prohibition as a solution to the latter. The work found that in Nigeria, because of the conservative view of divorce, the churches dissuade women experiencing domestic violence from divorce, just as they treat divorcees with contempt and segregation. Hence, there exists a correlation between divorce prohibition and spousal homicide because the latter is usually an outcome of domestic abuse. Therefore, the article argued that a solution to spousal homicide in Nigeria could arise from a reconsideration of divorce prohibition through a critical examination of the biblical texts upon which the doctrine is anchored.Contribution: This article is a contribution to the discourse on the spate of spousal homicide in Nigeria arising from domestic violence. It postulates a correlation between the Christian divorce prohibition and spousal homicide, and therefore proposes a reconsideration of this doctrine as a solution to the latter.

Authors: Vincent Wiso , Bosco Kyalo Kiema John
Published: September 2024

Renewable energy sources play a crucial role in reducing global reliance on fossil fuels. Advancements in technology has en- abled harnessing of renewable energy from solar, wind, and ocean tides to be viable. Solar energy, in particular, has gained significant global recognition as a renewable energy alternative. This study integrates Multi-Criteria Evaluation (MCE) and Geographic Information Systems (GIS) to assess Solar Photovoltaic Farms (SPVFs) suitability in Nakuru County, Kenya.

The study considered seven criteria including; slope, solar radiation, aspect, land use land cover, proximity to roads, power transmission lines, and settlements. These were evaluated using the Analytical Hierarchy Process (AHP) to generate weights for each decision criterion. The weights were used to overlay independent criteria maps that were formed as a result of the re- classification of each criterion from which a composite rated map was developed. Similarly, a composite restriction map was created by leveraging on constraint criteria including; protected ecosystems, water bodies, settlement areas, slope over 20%, proximity to roads, proximity to the transmission line, and land use land cover.

Results obtained from overlaying the composite rated and restricted maps reveal Nakuru County’s general suitability for SPVFs, except for Kuresoi North and Kuresoi South divisions which exhibit low solar radiation. Extremely-suitable areas ac- counted for 3.00% (224.14 km²), very-suitable areas 34.05% (2541.45 km2), moderately-suitable areas 7.76% (579.55 km2), marginally-suitable areas 1.47% (109.77 km2) while least-suitable areas covered 0.02% (1.39 km2).

The study provides valuable data and information for government agencies and investors to identify potential Photovoltaic (PV) system sites. Furthermore, the government is encouraged to establish a favorable framework for solar PV exploration and provide incentives to the private sector to facilitate the establishment of SPVFs.

Authors: Areias Pedro , dos Santos Charles , Melicio Rui , Silvestre Nuno
Published: September 2024

In this paper, we propose an implicit staggered algorithm for crystal plasticity finite element methodwhich makes use of dynamic relaxation at the constitutive integration level. An uncoupled version ofthe constitutive system consists of a multi-surface flow law complemented by an evolution law for thehardening variables. Since a saturation law is adopted for hardening, a sequence of nonlinear iterationfollowed by a linear system is feasible. To tie the constitutive unknowns, the dynamic relaxation method isadopted. A Green-Nagdhi plasticity model is adopted based on the Hencky strain calculated using a[2/2] Padé approximation. For the incompressible case, the approximation error is calculated exactly.A enhanced-assumed strain element technology is adopted, which was found to be especially suitedto localization problems such as the ones resulting from crystal plasticity plane slipping. Analysis ofthe results shows significant reduction of drift and well defined localization without spurious modes orhourglassing.

PROBING INTERPERSONAL METADISCOURSE IN PARLIAMENTARY GENRES; A SURVEY OF KENYAN PARLIAMENTARY COMMITTEE REPORTS
Authors: Ntalala Safari G.
Published: September 2024

Parliamentary deliberations rely on using language in order to convince or persuade. They involve purposeful and strategic manipulation of language to achieve communication goals. Metadiscourse is crucial to the art of persuasion and may be viewed in two ways: textual and interpersonal metadiscourse. This article focuses on interpersonal metadiscourse which involves interactional and inclusive aspects of the author. This study analysis aspects of interpersonal metadiscourse used in selected Kenyan parliamentary committee reports so as to achieve the genre’s communicative purpose. The findings offer insights into the interplay between parliamentary discourse styles and interpersonal metadiscourse as well as contribute to the pool of knowledge on parliamentary discourse and rhetorical analysis. The framework for analysis was based on Hyland’s (1998, 2005) model of metadiscourse. A descriptive research design was used with corpora being generated from fifteen parliamentary committee reports sampled from the National Assembly, county assemblies and the Senate of Kenya. Findings from the study indicate that diverse aspects of interpersonal metadiscourse including engagement markers, personal markers, hedges, and boosters are melded together; geared at guiding legislators through the reports and influencing their understanding, maintaining contact, providing perspective for interpretation, as well as convincing and persuading. Successful writing depends on how writers establish their stance, conduct interpersonal negotiations with readers and balance their claims through rhetorical choices. In the end, interpersonal metadiscourse in parliamentary reports serves to convey author’s presence, credibility, readers’ engagement, commitment to the message and organizes reports to ease interpretation, evaluation of information given and spark appropriate responses.

CAPITAL STRUCTURE DETERMINANTS IN A DEVELOPING ECONOMY: EVIDENCE FROM BANGLADESH
Authors: Tasneem Sadia , Masroor Imtiaz
Published: September 2024

Capital structure decisions are crucial for firms to enhance performance and maximize shareholder wealth. This study investigates the determinants of capital structure in Bangladeshi firms listed on the Chittagong Stock Exchange (CSE) from 2018 to 2022. The research utilises regression analyses to evaluate the relationships between financial leverage and key explanatory variables. By analysing various factors, including firm size, profitability, non-debt tax shields, growth opportunities, liquidity, and tangibility of assets, this research aims to identify the optimal mix of debt and equity financing. Using quantitative analysis, the study finds that several factors significantly influence capital structure decisions. Both fixed and random effects regression models are employed to analyse the data, revealing that profitability, non-debt tax shields, growth opportunities, and liquidity negatively impact financial leverage, while firm size and asset tangibility have positive associations. The Hausman test suggests that the fixed effects model is preferable, given its χ2-value of 93.52 with a p-value of 0.0000. The study concludes that the optimal capital structure is influenced by multiple factors, with no single theory universally applicable. The findings suggest that firms should carefully consider these factors when making capital structure decisions. Excessive debt can lead to financial distress, while appropriate debt levels can enhance performance. Understanding these determinants is essential for firms to optimize their financial strategies and achieve long-term success. This study contributes to the existing literature by providing insights into capital structure decisions in a developing economy like Bangladesh. It highlights the importance of considering specific factors and industry dynamics when making financing choices.

DYNAMICS OF EXCHANGE RATE AND FOREX RESERVES IN BANGLADESH: WAYS TO STABILIZE FOREIGN EXCHANGE RATE
Authors: Khaleque Md. Abdul , Eusuf M. Abu , Jahan Rounak
Published: September 2024

The exchange rate and foreign exchange reserves stand as pivotal determinants profoundly impacting external and overall economic conditions. A sustained equilibrium in exchange rates alongside robust reserve levels is imperative for managing inflation and fostering favorable trade balances, thereby, bolstering the nation's holistic economic well-being. This study scrutinizes the dynamic interplay of exchange rates and forex reserves in Bangladesh, drawing upon meticulously curated data from Bangladesh Bank and bruegel.org. Methodologically, the investigation relies on rigorous trend and growth models to elucidate pertinent patterns. The analysis unveils a phase of exchange rate stability vis-à-vis the USD to BDT currency pair pre-2022, followed by a marked escalation in recent years attributable to localized currency devaluation. Noteworthy is the trajectory divergence observed between the Nominal Effective Exchange Rate (NEER), demonstrating a downward trend, and the Real Effective Exchange Rate (REER), exhibiting a contrasting upward trajectory surpassing NEER. Moreover, a conspicuous surge in forex reserves is evident until early 2022, succeeded by a precipitous decline to precarious levels. This downturn is ascribed to multifaceted factors encompassing the Ukraine conflict, volatility in oil prices, burgeoning foreign debt obligations of public and private entities, dwindling Foreign Direct Investment (FDI) inflows, and diminished remittances. The governmental response has entailed the adoption of short-term strategies aimed at mitigating exchange rate volatility and preserving forex reserves. While certain measures have proven efficacious, others have fallen short of desired outcomes. In pursuit of exchange rate stability, the central bank has instituted a crawling peg exchange rate regime, complemented by governmental interventions restricting imports to safeguard forex reserves. Achieving equilibrium mandates concerted governmental endeavors to invigorate remittance and FDI inflows, thus fostering a more robust economic landscape.

Besides mother tongue interferences, mispronunciation of words is influenced by other factors, as disclosed in this study. Therefore, this paper explores college students’ mispronunciation and seeks ways to address this problem in the shortest time possible. Two English medium magazine articles were used as a platform to accommodate this study. Thirty words from the articles were identified to assess the students’ pronunciation. All these words were read by the students in context, not in isolation. The respondents for this study consist of six college students who are currently pursuing their diplomas at a private university. This study employed a one-group pre-test - post-test design and semi-structured interview. Two different treatments, pronunciation drills and tongue twisters, were used to address the problem. The analysis of the data revealed that the suprasegmental features were more dominant than segmental features in their mispronunciation, and the short treatments had helped in correcting the students’ mispronunciation effectively. The interview also confirms the effectiveness of these treatments in helping students improve their pronunciation.

Authors: Tirizite Youssef , Marjane Driss
Published: September 2024

The feeling of ownership and sense of control, often referred to as learner agency that students have over their learning, has recently garnered significant attention in English language teaching. Instructional strategies that empower learners have yielded promising results with regard to student engagement and academic outcomes. This study aimed to investigate the prevalence of high-agency practices among English teachers in Moroccan secondary education. Quantitative data was collected using a questionnaire. The sample comprised 130 Moroccan English teachers working in public schools. The findings revealed a strong inclination among the surveyed teachers towards utilizing teaching practices that support learner agency. However, certain areas, such as providing self-access opportunities and embracing uncertainty, exhibited varying frequencies among respondents. Despite these differences, the study highlighted that Moroccan English teachers are at the frontiers of pedagogical innovation. This research pinpoints specific areas for further development to enrich the cultivation of learner agency in language education.

Published: September 2024

The main objective of the current study is to identify the critical factors that affect employee commitment within one of the major insurance companies in Malaysia. The current study, based on the theoretical framework of the Theory of Planned Behaviour, analysed the influences of specific managerial practices, such as mentoring, job delegation, employee empowerment, and job rotation, on employee commitment. To achieve the set goal, a quantitative survey was conducted among 358 employees using a structured questionnaire. The study has indicated that mentoring, job delegation, employee empowerment, and job rotation of employees are positively related factors. The findings of the study suggest that the practice related to employee empowerment, which implies the possibility of providing workers with the needed amount of authority and autonomy, is the most influential factor. It indicates that companies should work on the improvements related to that area to ensure that their employees are dedicated. However, being significant as well, the need to mentor and delegate employees to outline their roles is stressed. The job rotation factor, although positively related, was insignificant. This may be explained as a result of the lack of suitable stimuli in the organization. Thus, the given insights provide practical implications for focused training and development interventions at Etiqa, Dataran Maybank.

THE LEVEL OF STUDIES AND LIFELONG LEARNING AS FACTORS SHAPING KNOWLEDGE, SKILLS AND ATTITUDES OF THE HUMAN RESOURCES OF SOCIAL SERVICES REGARDING ISSUES OF HUMAN RIGHTS
Authors: Chaidas Alexandros , Balias Stathis , Karalis Thanassis
Published: September 2024

This paper presents part of the results of a study conducted in the context of PhD studies of the first of the authors in order to assess a) the level of knowledge, perceptions, skills, attitudes and mobilization of human resources of social services on issues of protection of Human Rights (HR) of vulnerable social groups (VSG), and b) the impact on this level of both Lifelong Learning (LL) of human resources in the field of Human Rights and their level of studies. For data to be collected, a closed-ended electronic questionnaire was created and completed by four hundred and fifty-three active employees in social services operating in the three Regional Units of Western Greece. The most important results of the survey showed that the knowledge of human resources in the field of Human Rights was moderate. Moreover, it is concluded that the perceptions of human resources regarding the equality which VSG should enjoy in exercising their rights and receiving social benefits from the state range from very high to extremely high levels, respectively. At the same time, the emergence rate of socio-emotional skills during human resources contact with VSG appears to be adequate. On the contrary, the research data showed little mobilization of human resources to defend the rights of VSG within and outside the work environment. In addition, after correlating the categories of LL with the variables under study, the main results showed that the higher the levels of Formal Human Resource Education in the field of Human Rights, the less the various characteristics of VSG (gender, gender identity, sexual orientation, mental-physical disability, age, racial-ethnic origin, religion, socioeconomic status, language, skin color) constitute a barrier of discrimination during their contact with them, the more their socio-emotional skills emerge and their degree of mobilization increases. Finally, as the levels of studies increase, the higher the level of knowledge developed in the field of Human Rights by the participants in the research and the less the various characteristics of VSG affect the provision of quality services to them. On the contrary, the lower the educational level of human resources, the greater their mobilization within and outside the work environment.
