Injection of Renewables Gases Into the Existing Gas Distribution Grids and Employment of Reverse Gas Flow Technique
Authors: Jansons L. , Silina J. , Bode I. , Zemite L. , Zeltins N. , Palkova K.
Published: March 2024

Sustainability and longevity of existing gas grid exploitation perspective are closely related to two fundamental issues: their ability to adopt to changing gas fuel production and supply landscape in the context of methane-based fuels, mostly, biomethane, and in the context of non-methane-based fuels, mostly, low carbon and green hydrogen. Renewable gases and their ever-growing presence in gas transmission and distribution systems open up a discussion about the necessity to revise and restructure the original – vertically integrated layout of the gas systems, where gas supply is only technically possible from the transmission system towards distribution one, and not vice versa. Development of numerous decentralized biomethane production facilities connected to the gas distribution system causes a necessity to ensure the possibility to pass biomethane surplus of a certain production area into the gas transmission grid, thus avoiding necessity to install biomethane storage capacities locally and granting other regions an opportunity to use said surplus in their gas consumption immediately. The article addresses biomethane production trends and actions taken towards the development of reverse flow gas stations in France – one of biggest biomethane producers in Europe to date, and opportunities and challenges, which this technique might face in smaller and less active renewable gas markets as the one of Latvia.

Authors: Hanif A. , Putro I. E. , Riyadl A. , Sudiana O. , Hakiki  , Irwanto H. Y.
Published: March 2024

Quadrotor unmanned aerial vehicles (UAVs) are small, agile four-rotor systems suitable for various applications, from surveillance to disaster support missions. Hence, achieving high-precision trajectory tracking is crucial for their successful deployment. This research focuses on modelling, parameter identification, and Linear Quadratic Regulator (LQR) control design for quadrotors, aiming to enhance their trajectory following capabilities. The quadrotor dynamics are a sixth degree-of-freedom (6DOF) equation of motion derived from Newton’s second law, encompassing moment of inertia, centre of gravity, weight, and thrust of propeller parameters. Experimental measurements are conducted to accurately determine these parameters, ensuring a realistic representation of the quadrotor system. Subsequently, a linearized model is constructed to provide a suitable plant for control system development. The LQR control design is intended to improve the trajectory tracking performance. This control strategy is validated through simulation and practical experiments, demonstrating its effectiveness in achieving high-precision trajectory following capabilites. The proposed approach demonstrates that LQR control effectively guides the quadrotor to resemble a predefined trajectory, experiencing only 3 % overshoot observed during the initial phase of flight.

Authors: Babatunde Shakirat Adepeju
Published: March 2024

Research Question: How does the IPSAS application affect Accountability and government effectiveness in Nigeria? Motivation: Inadequate disclosure of public account information has made a mess of public resources management regarding accountability and government effectiveness, necessitating rational actions for minimising cover-up of unethical practices in government. This study employs Tawiah (2022); Schmidthuber et al. (2022) to tailor IPSAS and governance concepts. It creates unique constructs of voters' turnout rates to measure government effectiveness and buttress Accountability. Idea: This study examines governance status based on public support through the voters' election turnout. It anchors the research variables on the institutional and theoretical framework of IPSAS and public responses to government effectiveness Data: It analyses 1999 to 2020, a 22-year-time series data covering before and after the IPSAS application; obtained from the World Bank Development Indicators data bank and the National Assembly Federal Republic of Nigeria resources. Tools: It uses descriptive, ordinary least square regression, correlation statistical, and econometric analyses. Findings: During IPSAS application period, Accountability improves while government effectiveness declines. Whereas, during GAAP period, Government accountability progresses while Presidential and House of Representatives elections negatively influence the government's effectiveness. Hence, the Voters' turnout dwindled. Contributions: A unique methodology involving voters, political parties, officeholders, foreign direct investors and gross domestic products in studying government financial reporting standards. Combination of two regimes of GAAP and IPSAS to demonstrate deeper analyses of accounting standards and public performance evaluation. Evidences that the hidden economic problems associated with resource misallocation are aggravated during the IPSAS period.

Research Question: Does Gender Diversity positively or negatively affect the non-financial information on ESG? Motivation: This research explores the connection between ESG and the synthesis of the Board of Directors. More explicitly, we explore if the board's Gender Diversity improves non-financial information on ESG. Also, the effect of board gender diversity on ESG is under investigation as the findings in the current literature about the synthesis of board gender diversity are mixed. Considering this gap, this research tries to understand if Gender Diversity positively or negatively affects the non-financial information on ESG. Idea: This research article aims to study the relationship between gender diversity on board and European companies' environmental, social, and governance (ESG) ratings. It also examines the potential impact of European Directive 2014/95/EU, which re-quires disclosure of non-financial information, on this relationship. Data: The investigation used the dataset of 5,380 observations from 20 European countries from 2013 to 2022. Tools: The association between the ESG ratings and control variables was examined using regression analysis. Findings: The investigation results confirm a statistically significant impact between gender diversity and ESG performance ratings. The findings confirm conclusions drawn in other research studies. The adoption and enforcement of EU Directive 2014/95/EU had a remarkable and positive impact on European firms' ESG policies, as shown by statistical significance in several regression models. Gender diversity on company boards positively impacted all ESG models except the Governance Pillar Score. The investigation shows the importance of board synthesis, gender diversity, and additional variables concerning ESG reporting practices. Contribution: This research explores the connection between ESG and the synthesis of the Board of Directors. More explicitly, we explore if the board's Gender Diversity improves non-financial information on ESG. Also, the effect of board gender diversity on ESG is under investigation as the findings in the current literature about the synthe-sis of board gender diversity are mixed. Considering this gap, this research tries to understand if Gender Diversity positively or negatively affects the non-financial in-formation on ESG.
IFRS adoption and the value-relevance of financial statements figures in Nigeria
Authors: Imhanzenobe Japhet , Vincent Olusegun , Aworinde Olalekan
Published: March 2024

Research Question: Has IFRS adoption improved the value-relevance of financial statement figures in Nigeria? Motivation: The informativeness of the reported earnings, book values, and cash flows depends on the accounting standards used in preparing the financial statements. IFRS is a global set of accounting standards that tries to improve the relevance of accounting figures by recommending more realistic measurement and recognition criteria and increasing the level of disclosure of relevant information. Idea: The value relevance of accounting figures in predicting stock prices is widely acknowledged. However, this study tests whether IFRS adoption significantly improves this value-relevance by increasing the degree of correlation between accounting figures and stock prices in Nigeria. Data: The data were collected from the Bloomberg market data terminal and Datastream financial database. A sample of 85 listed companies was selected. The sample period was from 2007 to 2016. Tools: The study applied the Ohlson model (using fixed and random-effect models) along with the Driscoll-Kraay standard errors (DKSE) and Panel-corrected standard errors (PCSE) to anticipate autocorrelation, heteroscedasticity, and cross-sectional dependence biases. The Ohlson model was estimated separately for the pre- and post-IFRS adoption periods to detect changes in value relevance. The interactions of the IFRS dummy with earnings, book values, and cash flows were also estimated separately to detect the significance of IFRS interaction with the accounting figures. Findings: The results showed an overall increase in value-relevance by comparing adjusted R2s across the pre- and post-IFRS adoption period. Also, the interactions of IFRS with earnings, book value, and cash flows were all significant. Contribution: The study contributes to the existing literature by including cash flow in the value-relevance test in Nigeria and by applying estimation techniques that control for possible estimation biases. The authors recommend that investors pay more attention to these accounting figures under the IFRS regime when making investment decisions.

The Influence of the Soviet Law Model on Criminal Procedure Law in China
Authors: Zhiyuan Guo , Jiajia Yang
Published: March 2024

The first Criminal Procedure Law (CPL) of China, issued in 1979, was greatly influenced by the Soviet Criminal Procedure Law in multiple dimensions, including the framework, concepts, principles, and specific institutions. Although the Chinese CPL has changed a lot after three amendments in 1996, 2012 and 2018, respectively, the influence of the Soviet Law can still be noticed in many aspects of the current law. This paper will explore how Soviet Law has shaped Chinese CPL into the way it is. Part I will explore the historical development of Chinese CPL, indicating the close relationship between Chinese law and Soviet Law. Part II will compare Chinese CPLs with the Soviet (and its successor, Russia) CPLs, trying to identify their similarities and differences. Part III will draw some tentative conclusions from the comparison and predict the continuing influence of the Russian law model on Chinese CPL in the future. This paper will primarily rely on comparative study and historical analysis. The legal framework, legal terms, theories, principles, and specific institutions will be examined to illustrate the significant influence of the Soviet Law on Chinese Criminal Procedure Law. This study helps to better understand the evolution of Chinese criminal procedure law and predict its further development more accurately.
Enhancing the Responsibilities of Data Controllers in Vietnam: Insights from the European General Data Protection Regulation
Authors: Anh Dao Kim
Published: March 2024

This article explores the evolving landscape of data protection law in Vietnam, focusing specifically on the responsibilities of data controllers under Vietnam's new Personal Data Protection Decree (Decree No. 13/2023/ND-CP - hereinafter referred to as Decree 13) and compares it with the European Union's General Data Protection Regulation (GDPR). The main objective is to assess how the provisions regarding data controllers’ responsibilities under Decree 13 align with international data protection standards, identifying its progress and challenges. The analysis uncovers both convergence and divergence points between the related provisions under Decree 13 and the GDPR, particularly in terms of clarity, scope, and enforcement mechanisms. A significant challenge identified is the ambiguity in Decree 13’s provisions on data controllers’ responsibilities and the absence of several essential elements, which could undermine the effectiveness of Vietnam's data protection framework. To address these issues, the article offers strategic recommendations for legislative improvements and practical adjustments for data controllers in Vietnam. In conclusion, while navigating the path to a comprehensive data protection framework poses challenges for Vietnam, this journey offers an opportunity to align with regional and global developments in data protection laws. By learning from the GDPR and adapting to its specific features, Vietnam can develop a robust, effective, and trustworthy data protection environment, safeguarding its citizens' privacy rights and facilitating a favorable international business climate.
The Influence of the Soviet Legal Model on the Law Directing the Establishment and Operation of Vietnam and China's Central Banks
Authors: Nghia Pham Thi Hong
Published: March 2024

The Soviet legal model significantly influenced the legal stance, operation and organization of central bank branches in China and Vietnam. According to research on the effect of the Soviet legal model on the organization and operations of the Central Bank of China and the Central Bank of Vietnam, the Soviet legal model assisted Vietnam and China in creating major legislative frameworks for the banking sector. However, the legal status of Russian banks has evolved in the direction of being more autonomous and efficient; at the same time, the People's Bank of China branch was also restructured to be more streamlined and efficient. These are the areas in which the State Bank of Vietnam has to improve in order to grow more successfully.
From Real to Fictitious Personality: The Concept of Juridical Person in Soviet Civil Regulations and Influences on Russia, China and Vietnam
Authors: Luong Le Minh , Hoang Minh Duc
Published: March 2024

How did the Soviet “juridical person” concept impact the contemporary conceptualization of legal personality in Russia, China, and Vietnam? To find an answer to this inquiry, this article explores the historical progress of “juridical person”, tracing its origins from 19th-century theories, through 20th-century communist civil regulations, to its present form. To unravel the progression, the doctrinal method and comparative law methods serve as research methodologies. The theoretical framework surrounding “juridical person” recognizes two distinct doctrines: fictitious personality and real personality. With these doctrines, a careful examination of civil regulations in the targeted countries was undertaken. The findings reveal a remarkable consistency: all three legal systems predominantly follow the fictitious doctrine when conceptualizing “juridical person” in their civil regulations, especially their Civil Codes. While variations exist due to ideological and historical contexts, this uniformity emphasizes the enduring influence of Soviet law and legal tradition on legislators’ approach to this concept across these nations. The recent divergence also becomes comprehensible when observed from doctrinal and historical perspectives.
MachLine: Development of a Dirichlet-Based, Subsonic/Supersonic Panel Method for Unstructured Grids
Authors: Goates Cory D. , Houser Ammon M. , Hunsaker Douglas F.
Published: March 2024

To meet the growing need for fast supersonic flow solutions, the theory and implementation of a modern subsonic/supersonic, unstructured panel method are here presented. This work presents several improvements over legacy supersonic panel codes and available modern codes. Among these improvements are automatic methods for generating unstructured wakes, enforcing the Kutta condition at trailing edges, and placing interior control points. An efficient method for calculating domains of dependence on an unstructured mesh is also presented. For the first time in the literature regarding supersonic panel methods, a complete method for calculating influence coefficients is also described. The numerical sensitivities of the method are examined. Compared to analytic and experimental data, the method is accurate for small-perturbation flows. For example, the relative error in the root pressure coefficient on a straight wing in supersonic flow ([Formula: see text]) was calculated to be within approximately 7% of the analytic solution for a range of angles of attack. For a delta wing in supersonic flow ([Formula: see text]), the method is found to calculate lift slope and zero-lift drag to within 5% of experimental data. The method is also fast, having run times on the order of 1 minute for meshes with around 26,000 panels.
Flexible Quadrotor Unmanned Aerial Vehicles: Spatially Distributed Modeling and Delay-Resistant Control
Authors: Eraslan Emre , Yildiz Yildiray
Published: March 2024

This paper introduces an analytical framework for the derivation of distributed-parameter equations of motion of a flexible quadrotor. This approach helps obtain rigid and elastic equations of motion simultaneously, in a decoupled form, to facilitate the controller design. A delay-resistant low-frequency adaptive controller is employed, which prevents excessive oscillations due to flexible dynamics, compensates uncertainties, and addresses the inherent time delay. In addition to this, a delay-dependent stability condition for the overall system dynamics is obtained including the human operator with reaction time delay, the adaptive controller, and the flexible quadrotor dynamics with input delay. With comparative simulation studies, it is demonstrated that the flexible arm tip oscillations are significantly reduced when the low-frequency delay-resistant closed-loop reference model adaptive controller is used, compared to a closed-loop reference model adaptive controller and a conventional model reference adaptive controller.
Dynamic Model Fidelity Effects on Covariance Based Track Association
Authors: Park Woosang , Alfriend Kyle T.
Published: March 2024

This paper examines the performance of covariance-based track association with varying levels of dynamic model fidelity. To minimize the dynamic nonlinearities, the mean modified equinoctial (MME) elements are used. Ground-based radar measurements are generated by propagating the osculating orbits of 100 space objects in low Earth orbit using a [Formula: see text] spherical harmonic gravity model (JGM-3). Atmospheric drag, solar radiation, and third-body gravity are not considered. To associate two tracks, the two sets of states and covariances are propagated to a common time. The Mahalanobis distance between the two tracks is then used to determine whether they associate. A higher-fidelity dynamic model for state propagation improves association performance, while the fidelity of the dynamic model for covariance propagation does not have a significant impact. The MME-based track association demonstrates excellent performance when incorporating [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] in the MME state propagation as well as the MME covariance propagation with [Formula: see text]. It achieves an accuracy of 99.92%, a true positive sensitivity of 92.43%, a false negative sensitivity of 7.57%, a false positive sensitivity of 0%, and a true negative sensitivity of 100% when associating tracks separated by 10 days.
Augmented Space Integral Approach for Structural Reliability-Based Optimization
Authors: Yuan Xiukai , Wang Shanglong , Dong Yiwei , Yin Chunping
Published: March 2024

An efficient, fully decoupled approach is proposed to solve the structural reliability-based design optimization (RBDO) problem. The proposed approach utilizes augmented space integral and importance sampling (ASI-IS) to efficiently evaluate a functional relationship between the probability of failure and the design parameters, namely the so-called failure probability function. ASI-IS allows for the avoidance of both the intractable density fitting task associated with augmented space methods and the time-consuming repeated reliability evaluations associated with surrogate model approaches. The resulting functional relationship can be used to completely decouple the original RBDO problem into a deterministic one. Then, an iteration mechanism is constructed with gradually smaller design domains to enhance the efficiency of the optimization process. Furthermore, a sample reuse algorithm is proposed to improve the performance of the proposed approach by collecting the samples generated in previous iterations and reusing them in the current iteration in order to produce a better estimator of the failure probability function. Numerical and engineering examples, including a turbine blade and an aircraft inner flap, are given to demonstrate the efficiency and feasibility of the proposed approach.
Aeroacoustic Loading of Impinging Supersonic Boundary-Layer Interaction on Statically Deformed Surfaces
Authors: Kokkinakis Ioannis W. , Drikakis Dimitris , Michael Spottswood S. , Brouwer Kirk R. , Riley Zachary B.
Published: March 2024

This paper concerns the interaction of an impinging shock wave with a supersonic turbulent boundary layer over several distinct and permanently deformed surfaces, resulting in differences in the shock–boundary-layer interaction and the surface acoustic loading. High-order numerical simulations featuring two-dimensional surface deformations typically encountered in experiments are performed. The deformation amplitudes are up to half the incoming turbulent boundary-layer thickness. The results show that the high-pressure region about the shock impingement is significantly altered and can become narrower or wider depending on the local surface inclination of the deformed panel mode. The surface curvature is found to not significantly affect the separation and reattachment locations of the recirculation bubble. The power spectrum analysis of the pressure fluctuations along the panel’s midspan, where the surface attains the largest deformation amplitude, exhibits a rich and varied response. The pressure power spectrum is amplified in all of the surface deformation modes examined, with the magnitude of the amplification varying in the frequency domain, depending on the location and mode.
Scaling the Momentum Coefficient for Active Flow Control at Various Operating Conditions
Authors: Reddy K. Venkateswara , Woszidlo Rene
Published: March 2024

The momentum coefficient is one of the most commonly used parameters to quantify the aerodynamic performance and system output of active flow control (AFC). Estimating the momentum coefficient accurately through experiments is challenging. Several approaches exist to estimate the momentum coefficient in laboratory conditions. However, the question arises as to whether these models hold as ambient and supply conditions change during operation in flight. Therefore, computational fluidic dynamic (CFD) simulations were carried out on two exemplary AFC actuators (i.e., a fluidic oscillator and a steady jet nozzle) in a quiescent environment with supply pressure ratios ranging from 1.5 to 4; supply temperatures at 293, 550, and 800 K; and ambient altitude conditions at sea level and 10 km. When scaled with [Formula: see text], the mass flow for different conditions collapses as a function of the pressure ratio. Furthermore, the momentum coefficient collapses when scaled with [Formula: see text]. The existing models to calculate the momentum coefficient hold for changing ambient and supply conditions. Therefore, these models, in conjunction with scaling parameters, can be employed during the operation of an AFC system in flight with changing conditions in order to provide the desired momentum output. The paper discusses the details of the CFD results and the derivation of the scaling parameters.

This study determines the fear of COVID-19, healthy lifestyle behaviors, and nutrition knowledge levels of individuals during the COVID-19 pandemic. The study was conducted involving 509 people between the ages of 18 and 64 from December 2020 to April 2021. Data were collected online using a descriptive characteristics form, the COVID-19 Fear Scale, the Adult Nutrition Knowledge Level Scale, and the Healthy Lifestyle Behaviors Scale II. It was found from the study that women feared COVID-19 more than men (p<0.05). Individuals aged 35–44 scored higher in basic nutrition knowledge, while those aged 18‒24 scored lower in food preference knowledge (p<0.05). It was also found that individuals who were between 55 and 64 years of age, married, highly educated, employed in the public sector, of good economic status, and ill scored higher on the Healthy Lifestyle Behaviors Scale II (p<0.05). A weak positive correlation was found between the score of the Fear of COVID-19 Scale and scores of both food preference knowledge and health responsibility sub-dimensions (r=0.088, r=0.181; p<0.05). A weak positive correlation was also found between the nutrition knowledge score as well as the different sub-dimensions and the total score of the Healthy Lifestyle Behaviors Scale II (r=0.164, r=0.196; p<0.05). It was observed that fear of COVID-19, nutrition knowledge level, and healthy lifestyle behaviors were influenced by various socio-demographic characteristics, and that there was a relationship between these three elements.

According to government regulations, PAI and Behavior Based subjects in SMK are given the task of producing students who are pious and have noble character. However, in practice, learning PAI and Behavior Based at SMK Budi Utomo Way Jepara tends to focus on increasing knowledge. This condition is exacerbated by the presence of some students who practice despicable morals. Therefore, a PAI and Budi Pekerti learning model is needed which is oriented to the development of students' morals. The PAI and Behavior Based learning model based on emotional intelligence is seen as a solution, because this intelligence leads to moral development. The learning model is assessed from the aspects of validity, practicality and effectiveness. To achieve this goal, the Plomp model development research was used, which consisted of five phases, namely: 1) initial investigation, 2) design, 3) realization/construction. 4) test, evaluation and revision, and 5) implementation. The trial was carried out using a pretest-posttest pre-experimental design in eight classes of class XI students in the odd semester of 2021/2022. Data collected through interviews, observations, questionnaires / questionnaires, reflection sheets and action plans were analyzed using descriptive analysis, Kolmogorov-Smirnov and paired T-test. The results showed that 1) the learning model got a very valid score with an average value of 94.53 which means it is very valid, can be used without revision 2) the learning model is considered very practical with an average value of 95.83 which means it is very practical, can be used without revision, and 3) the learning model is considered very good and can improve morals. Thus the learning model can be used to foster the morals of students at Budi Utomo Way Jepara Vocational School, as well as an effective learning model or able to improve students' morals (attitudes) towards Respect and Obedience to Parents and Teachers.

This research is motivated by a learning environment that is realized to play a role in the learning process, one of which is Islamic Religious Education. The learning environment which is classified as a social and non-social environment still does not encourage an increase in PAI learning achievement. Writing this thesis aims to determine the influence of the social environment and the non-social environment either individually or jointly on PAI learning achievement. This study uses a quantitative approach, the analysis uses simple and multiple linear regression statistics. The population is 40 students consisting of students in class X, X1 and XII SMK IT Shodiqussalam, the variables in this study include the social environment,non-social environment and PAI learning achievement. Data collection using questionnaires and documentation. The results of the study obtained the first equation Y=47.665+0.430,with a significance value of 0.899. The second equation Y=41.327+0.480 with a significance value of 0.944. The third equation Y=38.791+0.608X1+0.979X2 with a significance value of 0.608. These results indicate the influence of the social environment on PAI learning achievement and the influence of the non-social environment on PAI learning achievement and together have an influence on PAI achievement at SMK IT Shodiqussalam.The conclusions in this study are (1) the higher the social environment, the higher the learning achievement; (2) the higher the non-social environment will result in higher learning achievement; and (3) the higher the social and non-social environment, the higher the learning achievement.
