Abstract

Due to the online availability of maximum information nowadays, the current era of digital processing is more vulnerable to cyber threats. It is really difficult to confine the cyber threat in its initial stage as enormous varieties of cyber threats are developing day by day, making it hard to understand their behavior at an early phase. Cyber threats may be initiated intentionally by someone or processed unintentionally. The intentional attacks are categorized as cyber crimes and the society has to face grave consequences due to them. The consequences which may be in the form of financial, psychological or social damage create problems for one and all. Sometimes they even pose threat to national security and peace and harmony of a country. Thus, cyber crimes need to be restricted by analyzing them thoroughly and looking into their impact on different sections of the society. An attempt has been made to study the various forms of prevalent cyber crimes and their social effects. Several preventive measures and future challenges have also been explored during this study.

Abstract

Numerous attempts have been made to reduce friction coefficients and wear rates of lubricants by enhancing their tribological properties. One of the methods used to change the properties is by adding nanoparicles to the lubricants. The addition of nanoparticles on commercially available lubricant extensively builds the viscosity of lubricants, accordingly being an intriguing resolution for enhancing the load carrying capacity of hydrodynamic bearing. This paper presents a state-of-the-art review on effect of nanoparticles based lubricants on static thermal behaviour of journal bearings. It provides a wide and good reference for researchers to be utilized. Finally, this communication states the further research directions for lubricant industry by utilizing nanoparticles to in cease efficiency and effectiveness.

Keywords
