Abstract : Background: In this study, the thermal management of electronic devices, specifically CPUs, using carbon nanotubes (CNT) dispersed in polyethylene glycol (PEG-400) under the influence of a magnetic field was studied. The research aims to optimize cooling performance by enhancing efficiency, extending the operating temperature range, and improving the reliability of such systems.......

Abstract : Cryptography, the science of encoding and decoding information, has a rich history that spans thousands of years, evolving from simple substitution ciphers to complex modern encryption algorithms. This paper explores the chronological development of cryptographic techniques, beginning with early systems used by ancient civilizations, such as the Egyptians and Greeks, and advancing through key milestones like the Caesar cipher and the Vigenère cipher. The role of cryptography during medieval and Renaissance periods is highlighted, with particular focus on......
