FICR-TEAS 2022 marks the third "FICR International Conference on Research, Technology, Expert Applications, and Sustainability (FICRTEAS)" scheduled for January 10-11, 2022, and organised by the Department of Computer Science & Information Technology at IIS (deemed to be University), Jaipur. Over the past decade, technology has advanced at an unprecedented pace, leading to the creation of Expert Applications that simplify our lives. The integration of AI, Big Data, IoT, Data science and Cloud computing has given rise to innovative apps, gadgets, robots, and many remarkable outcomes. However, it is crucial to address the ever-increasing threats associated with Expert Applications, ensuring they are carefully examined and mitigated. By doing so, we can protect society from the potential negative impacts of these technological advancements. Additionally, incorporating sustainability into these technological advancements is crucial to ensuring that we meet current needs without compromising the ability of future generations to meet their own. This conference will also address how sustainable practices can be integrated into the development and deployment of expert applications, promoting a balance between technological progress and environmental tutelage.
