Abstract Aim: This study aims to offer a comprehensive examination of the security vulnerabilities associated with blockchain technology, with the aim of identifying critical challenges and formulating strategic solutions to bolster system integrity and enhance user trust. Methods: The study employs a combination of literature review and case study analysis to explore specific vulnerabilities such as re-entrance attacks, transaction malleability,

Abstract The study focuses on enhancing network intrusion detection to enhance network security and prevent potential data breaches. We propose B-XGBoost, an ensemble learning model that combines bagging and boosting, using 10k cross-validation and Bayesian optimization for binary network intrusion classification. The proposed model was trained and tested on the CIC-ID2017 dataset. Decision Trees, Random Forests, Support Vector Machines, Naive

Abstract Various studies have explored the evidence of racial disparity in sentencing; they have tried to see whether the race of victims or ofenders plays a role in infuencing the decisions of judicial ofcers such as the jury and judges. There have been debates whether racial disparity occurs within the criminal justice system, which is meant to be fair and

Abstract Organisational culture greatly affects how an organisation operates and how the workforce interacts to carry out daily activities. Various scholars have linked strong organisational culture to high workforce productivity as a whole; the effect on specific constructs of productivity is yet to be outset. The main aim of this thesis was to analyse the link between organisational culture and

Abstract Currently, cases of data breaches are prevalent, partly due to the inability of the Intrusion Detection Systems (IDS) used to offer on-demand network protection through real-time intrusion detection. This study sought to develop an ideal machine learning model for enhancing accuracy in network intrusion detection to address this problem.

Abstract The twenty-first century has seen a vast technological revolution characterized by the development of cyber-physical systems, integration of things, and new and computationally improved machines and systems. However, there have been seemingly little strides in the development of user interfaces, specifically for industrial machines and equipment. The aim of this study was to assess the efficiency of the human-machine

Abstract Essentially, the United States Supreme Court plays a critical role in setting precedents that are followed by lower federal courts and state courts. This implies that faulty decision by the Supreme Court has a ripple effect, characterized by adversities in the delivery of justice across the board. Over the years, the United States Supreme Court has made various landmark
