Abstract:There is rapid development and change in the field of computer science today. These affect all areas of life. Emerging topics in computer science are covered in this book.
In the first chapter, there is a log data analysis case study that aims to understand Hadoop and MapReduce by example. In the second chapter, encrypted communication has been tried to be provided on IoT devices performing edge computing. In this way, it is aimed to make communication secure. Arduino is used as an IoT device. In the encryption process, AES encryption is used with 128-bit and 256-bit key lengths. The third chapter presents a more secure connection between the NodemCU and Blynk, using the AES algorithm. it is aimed to prevent a vulnerability in the connection of Google Home devices with IoT during the Blynk IoT connection phase. The next chapter presents a methodological tool based on an evaluation framework for integration of digital games into education (MEDGE), expanded by adding additional information from the students, MEDGE+. The fifth and last chapter proposes a disaster management system utilising machine learning called DT-DMS that is used to support decision-making mechanisms. Keywords:Hadoop and MapReduce, Edge Computing, Secure Connection, Practical Evaluation, Serious Games, Digital Twin, Disaster Management System
