Authors: Wulandari Putri , Nasik Khoirun
Published: March 2024

Financial institutions in Islam are governed by rules of halal (permissible) and haram (forbidden). One example of an Islamic financial institution is PNM Mekaar Syariah, which operates under various Sharia contracts. To ensure its Sharia compliance, it is necessary to analyze its pillars, conditions, and mechanisms. The objective of this research is to examine the Sharia compliance of the Mudharabah contract used in capital financing at PNM Mekaar Syariah, focusing on the branch in Prambon. This study adopts a qualitative descriptive approach. The findings reveal that PT PNM Mekaar offers Sharia-compliant capital financing products, as demonstrated by the research findings on the practice of capital provision by PNM Mekaar Syariah to its customers. However, there are some pillars and conditions that do not align with Sharia principles, leading to the deterioration of the Mudharabah contract's validity.

Strategic Importance of Compensation Strategy on Employee Performance: Evidence from Lekki Free Zone Area of Lagos State
Authors: SAKA Rahman Olawale, , ADELEKE Aishat , OLUBODUN Ayomide Shukura,
Published: March 2024

The study examines the strategic importance of compensation on employee performance in an organisation (a study of Lekki Free Trade Zone, Lagos), whose aim is to examine the impact of compensation on employee performance. The study concludes that adopting a better compensation strategy is essential to all organisations. However, because most businesses are unaware of the significance of compensation strategy, but managers often put pressure on workers to work hard despite receiving inadequate pay from the organisation. The study has shown that compensation and other benefits are strategic tools to organisations to influence their employees in order to remain competitive. If adequately developed, the compensation adds value to an organisation and increase workers efficiency in operation, quality service, customer satisfaction, and even achieving organisational goals. Organisations should ensure that their pay plan aligns with their strategic goals. They should also stay current on industry norms, perform frequent market evaluations to know if the company’s compensation packages are competitive and better in order to draw and keep good employees in organisation. Furthermore, they should implement other compensation benefits other than pay to influence employees towards better performance.

Published: March 2024

Universities in Nigeria are encumbered with serious challenges in the area of the organisational commitment of employees, ineffective leadership and low emotional intelligence, resulting in poor organisational outcomes such as low motivation and high turnover. In this study, investigation was carried out to find out the effect of perceived leadership style and emotional intelligence on organisational commitment of two private universities. Using a convenient sampling technique, 181 respondents participated in the study and two main hypotheses were tested using multiple regression analysis on SPSS version 20. The results indicated that though perceived leadership style has a statistically significant positive effect on organisational commitment, but of the three dimensions of leadership styles examined, only transformational leadership showed significant positive effect on organisational commitment with a p-value of .001 (p = < 0.05) and a beta value of .240. Both transactional leadership and laissez-faire leadership styles showed negative beta values (β =-.163; β = -.128 respectively) indicating a negative effect on organisational commitment. Emotional intelligence was discovered to have significantly positive effect on organisational commitment. Thus, it is recommended that more attention should be given to developing and exhibiting transformational leadership attributes in the private universities and also, emotional intelligence training should be regularly reinforced and given to employees of the educational organisations.

Authors: ADE-WILLIAMS Mercy Olufunke , YUNISA Simon Amodu
Published: March 2024

In this study, the correlation between Assets Management Corporation of Nigeria (AMCON) and bank stability was examined. The study used panel data collected from annual reports of five Deposit Money Banks (DMBs) for the period 2011 to 2020. The auto regressive distributed lag model (ARDL) was used to analyse data collected. Findings from the study revealed that bank’s capital adequacy has positive and significant impact on DMBs’ performance in Nigeria. Additionally, non-performing loans and liquidity ratio have positive and significant effect on DMBs’performance in Nigeria. To decrease the occurrence of nonperforming loans, it is recommended that banks continuously assess and enhance their loan risk management practices. This can be achieved through the implementation of robust credit risk management systems and the use of credit scoring techniques. Also, banks should diversify their loan portfolios to reduce their exposure to single-borrower concentrations and sector-specific risks. Meanwhile, Banks should improve their internal controls and governance practices to enhance their overall risk management capabilities and ensure compliance with regulatory requirements..

Published: March 2024

Kuala Lumpur is one of Southeast Asia’s most prominent modern cosmopolitan cities, having evolved from the federal capital. In consequence of this transformation, the population of Kuala Lumpur has expanded outward, leading to its city centre being mostly occupied by businesses and residents relocated to suburbs and more affordable areas. Increased commuting distances also facilitated the use of private automobiles which brings about the environmental issues. This research aims to determine factors influencing the behaviour and preferences of public transport passengers particularly Light Rail Transit (LRT) in Kuala Lumpur. In an effort to verify the theoretical model and the relationship between the variables, a structural equation model (SEM) was developed. Perceived Costs (PC), Attractive Alternatives (AA), Feeling towards Transit (FTT), and Service Quality’ (SQ) were considered as the parameters of the public transport services that could be the drivers for the key variables such as Perceived Benefits (PB), Satisfaction (SA), and Behavioural Intentions (BI). This model incorporates direct and indirect effects with the intention of providing insight into how the behaviour of transit passengers is influenced. The results indicate that Service Quality contributes to Satisfaction and Satisfaction contributes to Behavioural Intentions. According to the results, perceived benefits are positively related to satisfaction. The findings do not support the Service Quality and Attractive Alternatives as the significant indicators for the behavioural intentions. The reason for this outcome may have to do with the adverse impact of the COVID-19 pandemic on public transportation services, which in turn affected riders’ perception of these services.

Published: March 2024

The aim of this work, which is an aspect of my PhD thesis submitted to the Department of Psychology, University of Lagos, is to report the Entrepreneurship Model as a research outcome that used an empirical approach. Entrepreneurial Indicators Programme (EIP) by Ahmad and Hoffman (2007), was reviewed. Existing theories and models provided useful guide and direction for the development of the Jayeoba’s Entrepreneurial Model (JEM). Deriving from societal needs the JEM indicates both personality and contextual factors that are functionally related to produce entrepreneurial outputs like job creation and employment. Theories and models offer guide to further understanding of the concept of entrepreneurship. This way, policy decisions can be based on sound theoretical as well as empirical grounding with implications for reduction in mismatch between financial mediation as opposed to understanding of the interconnectivity among personality, environmental and financial content of entrepreneurship. This kind of connectivity was explored in the study, leading to the proposed entrepreneurial model.

However, the lack of standardized benchmark datasets hinders the comparative evaluation of anomaly detection algorithms. In this work, we address this gap by presenting a curated collection of preprocessed datasets for spacecraft anomalies sourced from multiple sources. These datasets cover a diverse range of anomalies and real-world scenarios for the spacecrafts. Furthermore, we have added two general datsets ensuring comprehensive evaluation and generalizability of anomaly detection algorithms. Our compilation process involves rigorous preprocessing steps to ensure data integrity and privacy protection. Each dataset is thoroughly documented, including descriptions of anomalies, preprocessing methodologies, and evaluation metrics. By providing this unified benchmark dataset, we aim to facilitate fair and transparent evaluation of anomaly detection algorithms, ultimately advancing the state-of-the-art in anomaly detection research.
On the Intersection of Signal Processing and Machine Learning: A Use Case-Driven Analysis Approach
Authors: Aburakhia Sulaiman , Shami Abdallah , Karagiannidis George K
Published: March 2024

Recent advancements in sensing, measurement, and computing technologies
have significantly expanded the potential for signal-based applications,
leveraging the synergy between signal processing and Machine Learning
(ML) to improve both performance and reliability. This fusion represents
a critical point in the evolution of signal-based systems, highlighting
the need to bridge the existing knowledge gap between these two
interdisciplinary fields. Despite many attempts in the existing
literature to bridge this gap, most are limited to specific applications
and focus mainly on feature extraction, often assuming extensive prior
knowledge in signal processing. This assumption creates a significant
obstacle for a wide range of readers. To address these challenges, this
paper takes an integrated article approach. It begins with a detailed
tutorial on the fundamentals of signal processing, providing the reader
with the necessary background knowledge. Following this, it explores the
key stages of a standard signal processing-based ML pipeline, offering
an in-depth review of feature extraction techniques, their inherent
challenges, and solutions. Differing from existing literature, this work
offers an application-independent review and introduces a novel
classification taxonomy for feature extraction techniques. Furthermore,
it aims at linking theoretical concepts with practical applications, and
demonstrates this through two specific use cases: a spectral-based
method for condition monitoring of rolling bearings and a wavelet energy
analysis for epilepsy detection using EEG signals. In addition to
theoretical contributions, this work promotes a collaborative research
culture by providing a public repository of relevant Python and MATLAB
signal processing codes. This effort is intended to support
collaborative research efforts and ensure the reproducibility of the
results presented.
Fixed-time and robust distributed state estimation for fractional-order linear systems based on fractional-order modulating functions
Authors: Zhang Yu-Qing , Liu Da-Yan , Boutat Driss , Wu Ze-Hao
Published: March 2024

In this paper, we propose a fixed-time and robust distributed state estimation method for fractional-order linear systems by developing a set of reduced-order centralized estimators at the networked sensor nodes. To begin, we introduce a recovered set and a connectivity assumption weaker than strong connectivity, which are crucial for constructing an invertible transformation at each node. Leveraging this transformation, each node’s unobservable state can be represented, and the relationship between the entire state at each node and the observable states of the nodes in the recovered set can be established. Building upon this framework, the fractional-order modulating functions method is developed to estimate each observable part, and a type of fixed-time and robust centralized state estimators are formulated by initial condition-independent algebraic integral formulas. Subsequently, based on the established relationship, by collaborating a recovered set of local reduced-order centralized estimators, fixed-time and robust distributed state estimation in noisy cases is realized. Additionally, in the discrete noisy case, a distributed estimation algorithm for online applications is generated through vector products and a detailed stability analysis for distributed state estimation errors is conducted to complement our proposed methodology. Finally, two numerical examples are provided to demonstrate the efficacy of the developed distributed estimation scheme.
Emergent Abilities of Graph Neural Networks for Large-scale Power System Analysis
Authors: Zhu Yuhong , Zhou Yongzhi , Yan Lei , Li Zuyi , Xin Huanhai , Wei Wei
Published: March 2024

The scale-up of AI models for analyzing largescale power systems
necessitates a thorough understanding of their scaling properties.
Existing studies on these properties provide only partial insights,
showing that loss function decreases predictably with increased model
scales; yet no scaling law for power system AI models has been
established, and model performance remains unpredictable due to
“emergent abilities”. This study pioneers the discussion on the
emergent abilities of graph neural network (GNN) for analyzing
large-scale power systems, revealing that model performance improves
dramatically once model scale exceeds a threshold. Furthermore, we
introduce an empirical power-law formula to quantify the relationship
between this threshold and the power system size. Our theory accurately
predicts the threshold for the appearance of emergent ability in
large-scale power systems, including a synthetic 10,000- bus and a
real-world 19,402-bus systems.

Authors: Basnayaka Chathuranga , Jayakody Dushantha Nalin K. , Beko Marko
Published: March 2024

With the increasing occurrence of wildfires globally, quick and
effective detection methods are vital. This paper proposes an innovative
solution for wildfire detection using Unmanned Aerial Vehicle
(UAV)-assisted detection systems. On the other hand, semantic
communication, a technology designed for efficient data transmission in
specialized tasks, plays a crucial role in next-generation wireless
communications systems. In this paper, the deep joint source-channel
coding (DJSCC) scheme has been used for efficient image transmission as
a deep learning-based semantic communication technique for wildfire
detection. DJSCC improves source and channel coding for semantic
communications, offering advantages such as improved energy efficiency,
reduced latency, and improved reliability compared to traditional source
and channel code schemes. In this paper, the transmitter-receiver
operations of the UAV communication system are modeled as a DJSCC, and
they are jointly trained while taking into account the effects of the
fading channel. The encoder transforms captured images into compact
feature vectors, subsequently transmitting them using a reduced number
of channels to minimize latency. Rather than engaging in the
reconstruction of the input image in the receiver, the classifier
performs a classification task using the received signals at the
receiver. Alternatively, if the recovery of an image is required to
understand the spread of the wildfire, the decoder reconstructs it by
using the received signal at the receiver.
BiTDB: Constructing A Built-in TEE Secure Database for Embedded Systems

Published: March 2024

In this paper, we propose BiTDB, a built-in Trusted Execution
Environment (TEE) database for embedded systems, to realize higher
system availability while ensuring data confidentiality. With BiTDB,
dilemmas the state-of-the-art research work on secure embedded
databases has to face can be significantly reduced and eliminated,
including (i) complicated research and realization on searchable
encryption algorithms (SEA), (ii) limited support to all database
operations, and (iii) almost none of specific design and optimizations
toward build-in TEE embedded databases. Through BiTDB, all database
operations can process plaintext in TEE instead of retrieving on
ciphertext by developing complicated SEAs. To enable BiTDB to handle
database files in Rich Execution Environmen (REE) as local ones, we
extend the TEE OS with generic file I/O libraries. Then, we contribute
three critical optimizations to significantly reduce redundant memory
and file operations between TEE and REE, and BiTDB achieve better system
performance and availability in embedded systems. Finally, we have
implemented the prototype system based on OP-TEE and SQLite for
several typical platforms, including virtualization and hardware
environments. The TPC-H test shows BiTDB can achieve 85% (on average)
of the original database performance while guaranteeing data
confidentiality and integrity. Our project repository is

Explainable Neural Dynamics Models for Electric Motor Temperature Estimation
Authors: Liao Xinyuan , Chen Shaowei , Long Yunxiang , Zhao Shuai
Published: March 2024

Accurate temperature estimation of permanent magnet synchronous motors
serves as the fundamental basis for designing effective thermal
management strategies. Model-based estimation methods exhibit superior
real-time performance, but the intricate modeling process requires
substantial expert knowledge and lacks versatility. Conversely,
data-driven estimation methods, while offering flexibility, often lack
physical implications in terms of system dynamics. This paper proposed a
structured linear neural dynamics model for motor temperature
estimation. This model is data-driven, with prior knowledge integrated
into its structure, which preserves flexibility while guaranteeing
system stability through the Perron-Frobenius theorem. Additionally,
this paper achieves the decoupling of control input from state
transitions and the embedded deployment of this model. The method is
validated with a real dataset. The lightweight feature is demonstrated
by the implementation of an STM32 Microcontroller with 1.808 KB and 27
mW. The paper is accompanied by the open source data and code at GitHub:
