Electric vehicle development has become a trending topic in recent years mainly considering the negative environmental effects of the global transportation sector and the ongoing global energy crisis. The question of whether electric cars are more environmentally friendly than their gasoline counterparts, and in which ways, has caught the attention of scholars. In this context, this paper undertakes a comparative analysis of the harmful emissions generated by battery-operated electric vehicles against petrol vehicles. The objectives of the study are to (1) understand the amount of greenhouse gas emissions during the entire lifecycle of battery electric vehicles from a supply chain perspective, taking into account the transportation of the product until it reaches the end customer and (2) compare the environmental impact of battery-operated and petrol-operated vehicles in China and the UK. The paper develops and analyses a case study presenting two vehicle models, Tesla Model 3 (battery electric) and Toyota Corolla (Petrol) and their emissions in China and the UK. Numerous evaluation methodologies are utilized to arrive at the conclusions including lifecycle evaluation as the primary approach, combined with the well-to-wheel and cradle-to-grave analysis techniques. The study reveals that battery electric vehicles performed better than their petrol counterpart in the respective countries. However, interestingly the study further reveals that the battery electric vehicle in China emitted more greenhouse gases than petrol vehicles in the UK. Therefore, the study emphasises the importance of decarbonising the national grid to reap the ultimate benefits of electric vehicles. © 2023 IEEE.

In this paper, the sampled-data stabilization problem under safety constraints is studied for nonlinear time-delay systems. In particular, a methodology for the design of sampled-data safe stabilizers is provided for nonlinear systems affected by state delays. As a first step, the new notion of Safe Steepest Descent Feedback (SSDF), continuous or not, is introduced by suitably combining the well-known notions of Steepest Descent Feedbacks and Barrier functions considered to cope with safety requirements. Then, the stabilization in the sample-and-hold sense theory is used as a tool to show the existence of a suitably fast sampling such that: the digital implementation of SSDFs, continuous or not, ensures the semi–global practical safe stability property of the related closed-loop system with arbitrarily small final target ball of the origin. In the theory developed here, time-varying sampling periods are allowed. The proposed theoretical results are validated through an application concerning the plasma glucose regulation problem in Type-2 diabetic patients via artificial pancreas.

Autonomous driving platoon control technology has gradually gained widespread attention, but public receptivity to it is shaped by a variety of factors, encompassing cognitive and personal characteristics. This study aims to understand these factors to promote the broader application of autonomous driving platoon control technology. Through questionnaires, we gathered data pertaining to the cognitive characteristics, individual preferences, and personal characteristics of the public. We used a structural equation model to analyze these data to determine the relationships and impact strengths between these factors. Results indicate that cognitive characteristics have a significant positive impact on individual preferences, particularly cognitive characteristics related to safety confidence and technological understanding. Personal characteristics also impact individual preferences. These findings may help policymakers formulate targeted policies by better understanding public needs and concerns. Moreover, it carries substantial implications for the advancement and utilization of autonomous driving platoon control technology, particularly with regard to marketing strategies. © ASCE.

This paper studies the Multiple Sources and Multiple Destinations (MSMD) routing problem in a dynamic Air-to-Air Ad-hoc Network (AAAN). We consider a spectrum-limited scenario where multiple links have to share the same frequency channel so that co-channel interference becomes inevitable. As a result, routing decisions and spectrum access are coupled and must be jointly considered. This paper proposes a deep Q-learning-based algorithm to find an optimal routing and channel selection strategy that minimizes the end-to-end communication delay. Specifically, under the assumption that only local information is available to every node, the Deep Q-Network (DQN) is trained offline to learn the optimal routing and channel selection strategy. After the trained DQN is implemented in every node, multiple relay nodes can simultaneously determine their next-hop relay and channel selections in real-time. Simulation results demonstrate the efficacy of our proposed algorithm. © 2022 IEEE.

This paper addresses the problem of safety-critical control for systems with unknown dynamics. It has been shown that stabilizing affine control systems to desired (sets of) states while optimizing quadratic costs subject to state and control constraints can be reduced to a sequence of quadratic programs (QPs) by using Control Barrier Functions (CBFs) and Control Lyapunov Functions (CLFs). Our recently proposed High Order CBFs (HOCBFs) can accommodate constraints of arbitrary relative degree. One of the main challenges in this approach is obtaining accurate system dynamics, which is especially difficult for systems that require online model identification given limited computational resources and system data. In order to approximate the real unmodeled system dynamics, we define adaptive affine control dynamics which are updated based on the error states obtained by real-time sensor measurements. We define an HOCBF for a safety requirement on the unmodeled system based on the adaptive dynamics and error states, and reformulate the safety-critical control problem as the above mentioned QP. Then, we determine the events required to solve the QP in order to guarantee safety, and derive a condition that guarantees the satisfaction of the HOCBF constraint between events. We illustrate the effectiveness of the proposed framework on adaptive cruise control and compare it with the classical time-driven approach.

Diabetes Mellitus has no permanent cure to date and is one of the leading causes of death globally. The alarming increase in diabetes calls for the need to take precautionary measures to avoid/predict the occurrence of diabetes. This paper proposes HealthEdge, a machine learning-based smart healthcare framework for type 2 diabetes prediction in an integrated IoT-edge-cloud computing system. Numerical experiments and comparative analysis were carried out between the two most used machine learning algorithms in the literature, Random Forest (RF) and Logistic Regression (LR), using two real-life diabetes datasets. The results show that RF predicts diabetes with 6% more accuracy on average compared to LR. © 2023 Elsevier B.V.. All rights reserved.

Applying machine learning methods to physical systems that are supposed to act in the real world requires providing safety guarantees. However, methods that include such guarantees often come at a high computational cost, making them inapplicable to large datasets and embedded devices with low computational power. In this paper, we propose Colsafe, a computationally lightweight safe learning algorithm whose computational complexity grows sublinearly with the number of data points. We derive both safety and optimality guarantees and showcase the effectiveness of our algorithm on a seven-degrees-of-freedom robot arm. © 1963-2012 IEEE.

Online learning, especially in higher education, is getting more attention in many countries in the past ten years as it provides several advantages to the learners including time and space learning flexibility. Student engagement in online learning has an important factor for the student to complete their study program and achieve their planned learning objective. Unlike in classroom learning, online learning does not provide resources such as instructor to maintain student engagement but Learning Management System (LMS). One approach to increase student engagement is by personalizing learning materials managed automatically by LMS. This paper presents experimental results on using context-sensitive recommender systems embedded in LMS to increase student engagement in online learning by personalizing recommended learning materials to the targeted students. The proposed LMS which adapts to student learning progress, recommendations are personalized by using student contextual information to make the generated recommendation fits the student learning progress. The results of this study indicate that contextual information as an additional feature of the student profile increases the correlation between the actual grade and the prediction grade using user-collaborative filtering. © 2022 IEEE.
