Published: November 2024

This research evaluates the effect of financial deepening and institutional factors on industrial value. Africa, rich in natural resources, stands poised for resource-based industrialization, yet many nations continue to export raw materials with minimal processing. According to World Bank data, Sub-Saharan African countries have seen a decrease in industrial value added over the years. This decline is partly due to insufficient integration between agriculture and manufacturing. The primary factors in converting raw materials into finished products are labor and capital. While Africa is abundant in intellectual capital, it faces challenges with financial capital. Despite the critical role of financial development in enhancing industrial sectors, institutional factors also play a significant role. This study, which involved 38 Sub-Saharan African nations, analyzes the impact of financial development and institutional factors on industrial value added using multiple linear regression. The findings reveal that both financial development and institutional quality positively influence industrial value added, particularly highlighting the importance of bank capital adequacy, ATM availability, regulatory quality, corruption control, and governance. On the other hand, exchange rates, foreign direct investment, trade openness, and inflation all have a negative impact on industrial value added.
Shifting Paradigms

Investigations into format shifts from physical to digital access in libraries often centre print materials. Similarly, recent calls to action for an increasing focus on acquisition of materials that support equity, diversity, and inclusion (EDI) efforts within postsecondary institutions often centre print resources. For academic libraries, media like film have unique access and acquisition models that do not correspond to print and pose unique challenges extending back to the Hollywood studios that create and distribute films. This paper explores the dual shifts in academic libraries toward collecting fewer physical films and collecting more content to support EDI mandates, and asks: first, whether the shift away from collecting physical media may also be a shift away from including diverse perspectives in film collections; and second, if we have the data to draw a measurable and demonstrable conclusion. A comprehensive literature review traces efforts to assess markers of diversity in large library collections and/or film collections over the past two decades and helps establish a methodology that combines analyzing data from the library catalogue and Wikidata. Findings revealed that the completeness and consistency of the data over time makes drawing strong conclusions difficult and demonstrated the challenges of this approach in addressing EDI analysis, even when augmenting catalogue metadata with Wikidata. Curation and choice are perhaps more important in building a diverse film collection than questions of format alone, despite the challenges in assessing and collecting film which is and has always been a format in rapid and continual flux.
Particle Filtering for Enhanced Parameter Estimation in Bilinear Systems Under Colored Noise
Authors:   Al Neelain University, College of Engineering, Khartoum, Sudan., Mageed Hag Elamin Khalid Abd El
Published: November 2024

This paper addresses the challenging problem of parameter estimation in bilinear systems under colored noise. A novel approach, termed B-PF-RLS, is proposed, combining a particle filter (PF) with a recursive least squares (RLS) estimator. The B-PF-RLS algorithm tackles the complexities arising from system nonlinearities and colored noise by effectively estimating unknown system states using the particle filter, which are then integrated into the RLS parameter estimation process. Furthermore, the paper introduces an enhanced particle filter that eliminates the need for explicit knowledge of the measurement noise variance, enhancing the method's practicality for real-world applications. Numerical examples demonstrate the B-PF-RLS algorithm's superior performance in accurately estimating both system parameters and states, even under uncertain noise conditions. This work offers a robust and effective solution for system identification in various engineering applications involving bilinear models subject to complex noise environments.

The brokerage industry plays a crucial role in the capital market, acting as an intermediary for the buying and selling of securities. This study examines the service quality dimensions provided by brokerage firms in Pokhara, Nepal, and their impact on investor satisfaction. The study focuses on three independent variables: reliability, responsiveness, and assurance, and their relationship with the dependent variable, investor satisfaction. The study utilized primary data collected through a survey of 105 respondents from various age groups, academic qualifications, occupations, and levels of experience. The responses were measured on a five-point Likert scale, and statistical analyses, including mean, standard deviation, correlation, and regression, were conducted using SPSS software. The descriptive analysis revealed that all the independent variables, except for the statement "The service is not delayed," had a mean value greater than 3, indicating that they are strong predictors of investor satisfaction. The correlation analysis showed a positive relationship between reliability, responsiveness, and assurance of service delivery with investor satisfaction in Pokhara valley. The findings suggest that service quality and investor satisfaction are interrelated, with higher service quality leading to higher investor satisfaction. The study also identified assurance of service delivery as the most important predictor of investor satisfaction in this context.

Context: Today’s digital world with millions of users results in vast amounts of data. This ‘big data’, characterized according to its volume, variety, velocity, and veracity, is impacting the lives of data users worldwide in many ways and has become important for day-to-day decision-making. Problem: Requirements engineering (RE) - approaches used to engineer user requirements - plays an important role in software development in general. However, when it comes to big data applications, it is unclear which requirements engineering approaches apply. There is therefore a need to investigate this further. Objective: This study aims to answer the following research questions: (1) How are requirements engineering (RE) activities performed to address the needs of stakeholders in the context of big data? (2) How are users' perspectives addressed in the RE activities in a big data context? (3) What are the requirements engineering approaches that have been proposed for big data project development? Method: To address our three research questions, we conducted a systematic mapping study focusing on requirements engineering and the existing requirements engineering approaches in software engineering in the context of big data projects. Findings: A total of 787 papers were examined, with 720 papers found through string-based search and a further 67 through snowball search. From the total search results, 17 relevant papers were identified and reviewed by applying inclusion-exclusion criteria. Findings show that in the realm of Requirements Engineering (RE) activities, there is a notable lack of emphasis on requirements negotiation, validation, and prioritization. Additionally, there is a scarcity of knowledge, methods, techniques, and tools tailored for conducting requirements engineering within the realm of big data. The user's role and perspective in RE are insufficiently considered. Although the goal-oriented RE approach is somewhat acknowledged among proposed methods, it has drawbacks such as neglecting the user's viewpoint, being relatively static and general in requirement representation, struggling to adapt to changing requirements, and having its effectiveness as the primary RE approach questioned. This approach primarily focuses on addressing the 'why' aspect of the system rather than the 'how' which aids in decision-making. Conclusion: Based on the findings, it is clear that there is a need for more research to be conducted to find a better way to have a suitable RE approach for big data application development.

Machine Learning methods have emerged as powerful tools for analyzing stellar clusters, which pose significant challenges. techniques such as DBSCAN and GMM have advanced remarkably in this domain. However, these clustering techniques exhibit imperfections and limitations, highlighting the need for careful data tuning and consideration of data characteristics to ensure meaningful result. The utilization of supervised Machine Learning techniques for membership determination of the stellar clusters, especially open clusters, can lead to more accurate results. However, the absence of dataset for training on an open cluster presents a significant hurdle. To address the problem, we’ve introduced a novel approach to generate a labeled dataset for training the super- vised Machine Learning models. Our approach leverages data from Gaia DR3 Catalog, which provides precise astrometric and photometric measurements for millions stars in Milky Way, to construct a comprehensive dataset. Our findings have significant implications for future astronomical research. By using Supervised machine learning techniques, we can achieve more accurate and efficient membership determination for stellar clusters, which can lead to a better understanding of the formation and evolution of galaxies. Our method not only enhances the accuracy of membership determination but also provides insights into the underlying data characteristics that influence cluster analysis.

Published: November 2024

Personally, Identifiable Information (PII) is any content that is sensitive that needs to be treated as secure and private. When data pieces such as a person's name, address, Social Security number, phone number, email address, and so on may be used to identify a specific individual, they are deemed PII. As organizations grow, so does their volume of data. This makes identifying and protecting such sensitive resources at a scale quite complex. In this project, we demonstrate where and how PII can be discovered and how we developed a working prototype of a tool that can easily detect PII images using advanced artificial intelligence (AI) techniques such Optical Character Recognition (OCR) and image classification using Convolutional Neural Networks (CNN).

Information geometry is a mathematical framework that analyses the structure of statistical models using concepts from differential geometry. It treats families of probability distributions as manifolds, where the parameters of each model determine the coordinate charts. By applying info-geometric tools, we can gain insights into the characteristics of these models. The approach involves characterizing the queueing system's manifold using information geometry and presenting the exponential of the information matrix. This integration of information geometry with queueing theory provides a novel perspective for analyzing the dynamics of queueing systems, incorporating relativistic and Riemannian concepts. Some G/G/1 applications to E-health are highlighted. Finally, closing remarks and the next phase of research.

Authors: Setiawan Arif Milando
Published: November 2024

An antenna can be used to detect an object. The dimensions of the antenna also affect the working frequency, the smaller dimensions, the higher the working frequency and the closer the antenna range to radiate waves. Therefore, a microstrip antenna with a small dimension size is needed, but the antenna radiation distance capability for radar systems still needs to be reduced. A microstrip dipole antenna with a spiral shape, measuring 5 cm, was meticulously designed and fabricated. The square dipole antenna, featuring an optimal design with the arm structure rotated in a clockwise direction, achieved an impressive return loss of -27.54dB with a VSWR of 1.83. The engineering refinement of the antenna design involved the addition of a square shape, which led to a significant and impressive improvement in performance. The second spiral antenna, operating at a frequency of 805MHz with an impressive bandwidth of 57MHz, exhibited a remarkable return loss of -30.83dB and a VSWR of 1.07.

The average age of nurses in the public hospital was 36.11 years (SD: 4.78), while those in the private hospital had a lower average age of 32.45 years (SD: 3.67). The results indicated a significant difference in the scores related to patient safety culture between the two groups of nurses. Specifically, nurses in the private hospital reported a higher patient safety culture compared to their counterparts in the public hospital, highlighting the disparities in perceptions and practices regarding patient safety in these different healthcare settings.
Conclusion Nurses employed in private hospitals reported a higher level of patient safety culture compared to those working in public hospitals. This finding underscores the importance of creating a comfortable work environment in healthcare settings, as it is essential for minimizing the risk of patient safety incidents. By fostering a supportive and safe atmosphere, healthcare facilities can enhance the overall quality of care provided to patients and promote better outcomes in both private and public hospitals.

This work considers the design of a wave energy converter employing the WITT device: a machine that is able to convert motion in all 6 degrees of freedom into electrical power. Various designs for housing the WITT device inside a buoy are investigated with the aim of converting the forcing from low-frequency ocean waves to a higher-frequency motion that the WITT generates power most effectively at. By modelling the rigid-body motion of a buoy in response to a provided ocean wave forcing and the dynamics of the internal mechanisms within the buoy, we explore how nonlinear oscillation dynamics may achieve the desired frequency amplification.

Background

To analyze the characteristics of blood metabolites within 24 h after birth in preterm infants with bronchopulmonary dysplasia (BPD) and to identify biomarkers for predicting the occurrence of BPD.

Methods

Dried blood spots (DBS) were collected at birth from preterm infants with gestational age (GA) of less than 32 weeks in the cohort. The infants were divided into the BPD group and non-BPD group based on whether they eventually developed BPD. Dried blood spot filter papers were prepared from venous blood collected within the first 24 h of life. Metabolites were measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS) and analyzed using the R software package.

Results

DBS samples from 140 infants with the GA < 32 weeks were used in the study, with 4 infants who died being excluded. Among the remaining 136 preterm infants, 38 developed BPD and 98 did not. To control for GA differences, we conducted a subgroup analysis. In the GA 24+4–27+6 weeks subgroup, we observed a significant decrease in histidine levels and the ornithine/citrulline ratio in the BPD group. Additionally, the ratios of acylcarnitines C3/C0 and C5/C0 were also significantly reduced.

Conclusions

Metabolic markers in DBS within 24 h after birth are promising for predicting the occurrence of BPD in preterm infants with GA < 28 weeks.

Structural building components such as columns, beam and slab require formwork in its construction. Formwork plays an important role in forming the dimensions of the structure to fulfill the design. This study aims to determine the formwork comparison between conventional and aluminum in terms of characteristics, implementation methods and costs. This study compares the characteristics, implementation methods and costs using quantitative and comparative methods. Data on aluminum and conventional formwork were obtained by observing the project site implementation and studying the literature. In the construction of project mall X building, several types of formwork were used, including semi-system formwork (semi peri) and aluminum formwork used for columns and conventional formwork used for beams. That consideration is needed to determine the most efficient formwork in terms of characteristics, method of implementation and costs. The result shows that in project mall X building, aluminum formwork has the same cost as conventional formwork but the process is faster and more efficient than conventional formwork. In addition, aluminum formwork does not produce wood waste and can be reused for 150-200 installation. after the researchers analyzed the installation of the formwork system in the mall X construction project. For the development of further research, it is suggested to make a comparison of project X with other projects, besides that it also makes a comparison of the types of formwork with several variables so that it can consider the use of the type of formwork in terms of construction needs.
