CFD Analysis in LAA Thrombus Formation Risk
Atrial fibrillation (AF) is a common cardiac arrhythmia characterized by irregular and rapid electrical activity in the atria, leading to ineffective contraction and poor blood flow. More than 90% of the left atrial (LA) thrombi that cause thromboembolic events during atrial fibrillation (AF) develop in the left atrial appendage (LAA). Computational fluid dynamics (CFD) analysis can be used to better understand the risk of thrombus formation and subsequent embolic events.

CFD Modelling of Slurry Flows
Slurry pipe transport has directed the efforts of researchers for decades, not only for the practical impact of this problem, but also for the challenges in understanding and modelling the complex phenomena involved. The increase in computer power and the diffusion of multipurpose codes based on Computational Fluid Dynamics (CFD) have opened up the opportunity to gather information on slurry pipe flows at the local level, in contrast with the traditional approaches of simplified theoretical modelling which are mainly based on a macroscopic description of the flow.

Challenges for Commercialization of Second-Generation Biorefineries
Second-generation biorefinery refers to the production of different types of biofuels, biomaterials, and biochemicals by using agri-based and other lignocellulosic biomasses as substrates, which do not compete with arable lands, water for irrigation, and food supply. From the perspective of transportation fuels, second-generation bioethanol plays a crucial role in minimizing the dependency on fossil-based fuels, especially gasoline. Significant efforts have been invested in the research and development of second-generation bioethanol for commercialization in both developing and developed countries.

Challenges in Sewer System Maintenance
A sewer system is an important infrastructure of every settlement. A sewer system is a set of construction facilities used for the quick removal of wastewater from the humans’ immediate environment and its transport to a wastewater treatment plant or direct discharge into an appropriate recipient. In order for the sewer system to perform its purpose properly, its proper maintenance is required. Maintenance of a sewer system is very demanding since the system is mostly underground which makes it difficult to be accessed and maintained. The maintenance of a sewer system can be preventive (regular) or corrective (reactive). The regular maintenance occurs at certain intervals, whereas the reactive maintenance occurs in the case of some unforeseen event. This paper presents the history of sewer systems, as well as basic and alternative types of sewer systems. Furthermore, challenges that arise during sewer system maintenance and difficulties that maintenance employees face in their work are presented in this paper, as well as the ways in which sewer systems are maintained.

Challenges in the Field of Autonomous Vehicles
The term autonomous vehicle (AV) has become ubiquitous in our lives, owing to the extensive research and development that frequently make headlines. Nonetheless, the flourishing of AVs hinges on many factors due to the extremely stringent demands for safety, security, and reliability. Besides lingering technical problems, the complexity of the AV infrastructure makes it vulnerable to security and privacy attacks that can endanger the lives of passengers and commuters. Surpassing traditional centralized security systems, blockchain has emerged as the best solution to provide the much-needed security shield to AVs with its data transparency, immutability, and decentralized approach. Therefore, enriching and enmeshing technologies like AI, edge computing, IoT, 5G and Blockchain into a robust system will lead to the realization of our much-yearned AV dream into reality.

Challenges of Adopting Artificial Intelligence to Industry 4.0
Corroborating with Industry 4.0, Artificial Intelligence (AI) emerges as a field of computer science that aims to develop systems capable of performing tasks that require human intelligence, such as learning, reasoning, perception, language, and decision-making. The adoption of Artificial Intelligence technologies in Industry 4.0 emerges as a problematic issue due to the challenges of various characteristics that hinder or limit this adoption.

Chang Bogo-Class Submarine
The Chang Bogo-class submarine (Hangul: 장보고급 잠수함, Hanja: 張保皐級潛水艦) is a variant of the Type 209 diesel-electric attack submarine initially developed by Howaldtswerke-Deutsche Werft (HDW) of Germany , intended for service with the South Korean Navy and Indonesian Navy. A Daewoo (DSME)-upgraded model of the Chang Bogo class Type 209 is being independently exported by Korea to Indonesia in 2012, after a series of heavy competitions from Russian, French, and German-Turkish consortiums including from Germany's original Type 209. The variant is being considered for possible purchase by Thailand as well, as both newly built and second-hand options. The class is named for ancient Korean maritime figure Jang Bogo.
