To ensure the stability of the flying wing layout unmanned aerial vehicle (UAV) during flight, this paper uses the radial basis function neural network model to analyse the stability of the aforementioned aircraft.

This paper uses a linear sliding mode control algorithm to analyse the stability of the UAV's attitude in a level flight state. In addition, a wind-resistant control algorithm based on the estimation of wind disturbance with a radial basis function neural network is proposed. Through the modelling of the flying wing layout UAV, the stability characteristics of a sample UAV are analysed based on the simulation data. The stability characteristics of the sample UAV are analysed based on the simulation data.

The simulation results indicate that the UAV with a flying wing layout has a short fuselage, no tail with a horizontal stabilising surface and the aerodynamic focus of the fuselage and the centre of gravity is nearby, which is indicative of longitudinal static instability. In addition, the absence of a drogue tail and the reliance on ailerons and a swept-back angle for stability result in a lack of stability in the transverse direction, whereas the presence of stability in the transverse direction is observed.

The analysis of the stability characteristics of the sample aircraft provides the foundation for the subsequent establishment of the control model for the flying wing layout UAV.

This paper aims to investigate the impact of board gender diversity (BGD) on firm financial stability during the COVID-19 pandemic compared to the pre-pandemic period.

Difference-in-differences method was used for a sample of 891 US companies observed from 2018 to 2021.

The results indicate significant negative relationships between BGD and financial stability. The authors put in evidence a nonlinear relationship between BGD and financial stability. Also, the authors found that internal women directors as well as external ones decrease financial stability.

The results emphasize the beneficial effect of having more women on corporate boards during health crises and suggest that policymakers should take measures to promote BGD.

This paper highlights the impact of BGD on financial stability and provides additional evidence on the usefulness of BGD as an effective tool for crisis management.

This study aims to investigate whether the changes in gender composition of bank board affects Vietnamese bank stability efficiency.

This research covers a panel of 27 commercial banks in Vietnam over a 14-year period from 2007 to 2020. The two-step system generalized method of moments is used to estimate the gender diversity–Vietnamese bank stability efficiency nexus.

The authors find that a greater degree of board gender diversification enhances bank stability efficiency and reduces bank risk-taking in Vietnam. The relationship between gender diversity and the stability efficiency of Vietnamese banks is still valid under the influence of regulatory capital sufficiency and during the financial crisis. These findings are robust to alternative proxies for risk indicators and consistent with the perspectives of stakeholder and behavior theory.

Although this research revisits the relationship between gender diversity and bank risk-taking, it is the first attempt to explore the role of women on board in enhancing the stability efficiency of banks, using the stochastic frontier approach. These findings shed light on the function of gender diversity as a governance instrument for mitigating risk in an emerging market context.

This study aims to examine the various internal and external factors affecting the financial stability of Indian Commercial Banks. The aim is to improve the effectiveness of the Indian banking system in facilitating the transmission of monetary policy and to strengthen its resilience in the event of a banking crisis.

A panel data regression analysis is employed on unbalanced panel data of Indian commercial banks including public sector, private sector and foreign sector banks for the period of 2005–2022.

This study revealed that Indian banks with higher profits and high capitalization are more stable than others. However, banks with large bank size and high management costs are less stable as compared to other banks. In the case of macroeconomic variables, foreign exchange reserves have a significant positive impact on banking stability. Moreover, the unemployment rate has a significant negative impact on the banking stability of India.

Research identifies relevant micro and macroeconomic drivers pertaining to India’s banking stability, a developing economy. These findings have significant implications and can attract the attention of analysts, regulators, bankers and academicians in this area. Nevertheless, the scope of the study is limited to the variables chosen to evaluate their contribution to banking stability, but other variables may influence Indian banking conditions.

Indian banks are advised by the research to place a high priority on profitability, capitalization and effective risk management. Customers and investors should choose banks with strong metrics. The priorities for policymakers should be preserving robust reserves and tackling unemployment with focused initiatives. Adopting digitalization can improve banks’ customer service and operational effectiveness, which is important for overcoming economic obstacles. These tactics provide doable measures to improve the resilience and stability of the banking industry in India and other emerging nations.

This research differentiates from the rest by focusing solely on the Indian banking system, in contrast to previous ones that often treated India as part of a bigger part like the BRICS or South Asia continent. It acknowledges the need to comprehending the unique traits and difficulties faced by the Indian banking system. Moreover, the current study distinguishes itself by focusing on the combined impact of microeconomic and macroeconomic indicators in the Indian context, unlike earlier research that concentrated on assessing the effects of individual variables. The current study also investigated new variables like corporate governance and foreign exchange reserves in the context of Indian banking which have not been explored by existing literature. Research is also crucial in the context of the analysis’s time frame, since it captures the period of economic transformation that included demonization, implementation of GST, major mergers and global COVID-19 pandemic.

This study aims to analyze the impact of board gender diversity (BGD) on a bank’s financial stability. Moreover, it also examines whether digitalization and income diversification act as mediators (individual and serial) in this relationship.

Hypotheses were tested using data from Pakistan’s banking sector financial statements from 2017 to 2021. A two-step analytical approach was used: panel regression in STATA for initial hypothesis examination, followed by mediation analyses using bootstrapping in SPSS. In addition, mixed-effect ML regression was conducted to verify causation and ensure robust findings.

Results demonstrate that BGD, digitalization and income diversification are positively associated with higher financial stability. Moreover, as hypothesized, both digitalization and income diversification individually and sequentially mediate the relationship between BGD and banks’ financial stability.

It is important to acknowledge the study’s limited five-year timeframe. Further investigation is needed to determine the optimal board compositions, especially considering the study’s inclusion of up to 25% female directors on boards.

Policymakers and top management should prioritize increasing the number of female directors on boards for diversity. Banks that involve female directors can benefit from the synergies between gender diversity and digitization, along with the unique perspectives these women offer. This cooperative dynamic enables banks to explore and capitalize on innovative income diversification opportunities, enter new markets and ensure financial stability.

Research findings emphasize promotion of gender equality and meritocracy through increased female director representation. This fosters a more inclusive and cooperative decision-making culture, benefiting individual banks and setting a model for other sectors. Ultimately, it contributes to greater social acceptance of women executives.

The study reveals a novel mechanism, emphasizing the revolutionary impact of active female directors in tandem with digitalization, amplifying chances for income diversification and accelerating increased bank viability.

Children and youth who enter the care system have lower educational outcomes and university participation rates than their peers. This study aims to understand trend exceptions by examining the background of care-experienced undergraduates attending a research-intensive university in Canada.

Informed by social affordance theory, this study examined the presence of four indicators of stability (home, household occupants, school and legal status) during participants’ final three years of secondary education. Care-experienced undergraduates (N = 30) completed an online questionnaire. Associations between stability indicators, child welfare involvement in the final year of high school, educational outcomes and routes into higher education were analysed.

Stability across three to four indicators was experienced by 40% of participants, while 47% reported changes across three to four indicators. Only 20% had a change of school as compared to 47%–60% for other indicators. During their final year of high school, 73% of participants were supported by the child welfare system, with 50% being supported via a support program specifically for 16- to 18-year-olds. Stability scores were significantly lower for this latter subgroup compared to those who spent time in foster or group care and those who did not receive child welfare support during the final year of high school. Ninety percent of participants graduated from high school, 67% with the grades required to attend university. Three trajectories into undergraduate study were identified but could not be predicted using regression models.

This paper focuses on what has supported progression into a research-intensive university for care-experienced young adults and highlights the role of support programs for 16- to 18-year-olds.

This paper aims to present the results of aerodynamic calculation of impact the main rotor on the fuselage and the tail of a light gyroplane. This kind of vehicle is a type of rotorcraft which uses a non-powered rotor in autorotation to develop lift and engine-powered propeller to provide the thrust. Both of them disturb the flow around the gyroplane body (gyroplane fuselage and tail) and influence on its static stability. The main goal of the presented research was to find the magnitude of this influence. To measure this effect, the main stability derivatives changes of gyroplane body were investigated.

The CFD analysis of the complete gyroplane was made. Computation was performed for the model of gyroplane which was equipped with the two sub-models of the main rotor and the engine-powered propeller. Both of them were modelled as the actuator discs. This method allows to compute the aerodynamic impact of rotating components on the gyroplane body. All aerodynamic analysis was made by the MGAERO software. The numerical code of the software bases on the Euler flow model. Next, the resulting aerodynamic coefficients were used to calculate the most important stability derivatives of the gyroplane body.

The result obtained by computation presents the change in the most important aerodynamic coefficients and stability derivatives of the gyroplane body caused by the impact of its main rotor. Moreover, the result includes the change of the aerodynamic coefficients and stability derivatives caused by change of the main rotor configuration (change of rotation rate and angle of incidence) and change of the flight condition (gyroplane angle of attack sideslip angle and flight speed).

Analysis of the main rotor impact will be very useful for evaluation of dynamic stability of the light gyroplane. Moreover, the results will be helpful to design the horizontal and vertical tail for the light gyroplane.

This paper presents the method of the numerical analysis of the static stability of the light gyroplane’s body. The results of analysis present the impact of disturbance generated by the rotating main rotor on the static stability of the gyroplane body. Moreover, the impact of the main rotor configuration change and the flight condition change on the static stability were investigated too. The evaluation of the gyroplane’s body static stability was made by the stability derivatives. The methodology and obtained result will be very useful for analysis of the dynamic stability of the light gyroplanes. Moreover, the results will be helpful during design the main components of the gyroplane like vertical and horizontal tail.

In order to research the law of the low‐frequency power oscillation which often exists in the synchronous generator rectification system, the purpose of this paper is to study theoretical analysis and numerical calculation on the static stability of the system.

Different from the common three‐phase synchronous generator operating in large power networks, the stability of synchronous generator rectification systems is much more difficult to analyze because of its nonlinear loads. Some papers have analyzed the stability of the synchronous generator rectification system and presented different parameter conditions of system stability, but since factors that influence the system stability are complex, the essence of this kind of oscillation is not completely known yet. By considering rectification systems as an equivalent to DC circuits, the correct circuit model which is necessary to analyze the rectification systemic stability is set up, the changing law and relationship of various parameters under mini‐disturbances is analyzed, a linear differential equation about the DC‐side average current is derived, the stability of the synchronous generator rectification system is analyzed and deduced by using Hull criterion, all parameters influencing system stability are calculated and analyzed, and their ranges for a stable rectification system are given. Also, the reason why and how the parameters affect system stability is explained.

The operational stability of synchronous generator rectification systems is completely and correctly recognized.

The paper has a reference value for the design and safe operation of synchronous generator rectification systems.

The paper puts forward system stability criterion and gives a rational physical explanation about system stability.

In the recent financial crisis, many observers have assigned monetary policy a central role in the crisis. Specifically, they claim that excessively easy monetary policy by the Federal Reserve in the first half of the decade helped to cause a bubble in housing prices in the USA. The purpose of this paper is to analyze the role of monetary policy within the regulatory frameworks of financial markets.

The authors show within a macroeconomic framework a possible trade‐off between price stability and financial stability by differentiating between a technology‐driven bubble and an animal spirit bubble. In their conclusion: if there is a trade‐off between price stability and financial stability, the central bank will have to make a choice between the two objectives. In that case, the question arises of which of the two objectives should take precedence: price stability or financial stability?

From this analysis, the authors conclude that a central bank which uses a lexicographic ordering favoring price stability over other objectives is likely to fuel the boom inadvertently (in the case of a technology‐driven bubble) or will decide to do nothing (in the case of an animal spirit bubble) allowing a process of excessive credit creation. The latter seems to be what happened between 2003 and 2008.

If one wants to reduce the likelihood of future major financial busts, it must be accepted that the central banks (especially the Fed and the ECB) cannot only be responsible for price stability. Maintaining financial stability by preventing excesses in financial markets should be an equally important objective.

The paper gives a new perspective on the role of monetary policy within the regulatory framework. With this macroeconomic framework, the authors are able to show possible trade‐offs between price stability and financial stability. The micro‐ and macro‐prudential approach of this paper is a useful contribution to the discussion about regulatory reforms of financial markets.
