Fuzzy Logic-based Power Management System for Self-Powered Green IoT Edge Devices
W.D. Madhuka Priyashan1, Navod Neranjan Thilakarathne and Rohan Samarasinghe

The Internet of Things or IoT refers to the billions of devices that are connected to the Internet for intercommunication between each other, allowing Machine to Machine communication. As the IoT is capable of offering many convenient solutions, this paradigm is becoming so much popular creating a huge boom all around the world. Owing to the billions of devices that connect our daily life with the cyber-physical world, powering up these IoT solutions is becoming a big challenge, whereas self-powered IoT devices are becoming a viable solution in which researchers are currently working on. In this regard, many researchers have researched; to power up these IoT devices with renewable energy sources, where solar power is considered to be the key solution that is majorly accepted worldwide. However due to the cyclic variation of the receiving light intensity throughout the day and the unexpected interruptions due to weather conditions are becoming some of the major unresolved challenges pertained to these solar-powered IoT devices, where it requires a backup power source for solar-powered IoT devices with the need of continuous data harvesting throughout a long period of time. The environmental effects raised by removing batteries which is used as key the backup power source in IoT devices will become a major problem in the near future. Hence, in order to address this challenge and to offer a green solution that lowers the effects to the environment, we are presenting a fuzzy logic-based power management system in the context of Green IoT (GIoT).

Security Issues and Challenges in Windows OS Level
Uthuma Lebbe Muhammed Rijah and U.U. Samantha Rajapaksha

An operating system is a software that controls and communicates with the computer's hardware and offers the most fundamental services to other applications. The operating system is a very important component of the system software of a computer system, functioning as a channel between users and hardware. Today's commercial operating systems contain bugs and security flaws. The objective of any operating system manufacturing company is to provide a reliable operating system that can resist attacks and offer a secure computing environment to safeguard a computer's valuable assets. Windows is a Microsoft Corporation personal computer operating system part of the Windows NT family. The various security issues of the Microsoft Windows Operating System are deeply analyzed in this paper.

Impacts of Technology based ESL Writing Skills at Tertiary Level
Shanmugayogini Ravindran

The ESL learners face challenges in learning writing skills especially through the traditional mode. This study explores the effects of using technology-based computer assisted language learning (CALL) on the development in the proficiency in writing skills of the target group. A qualitative and quantitative mixed methodology was utilized to gather data. Two hundred students from the first-year arts were selected as participants for this study. A pretest on writing skills was conducted to gauge their proficiency in writing skills. After introducing and using the technology based (CALL) ESL writing skills for a semester, a post test was designed to see their development in the proficiency in writing skills. The teachers’ observation, questionnaires, interviews, the participants’ performances in pre and post writing skills and literature relevant to the study were utilized as data for the study. The findings reveal the fact that the CALL- a technology-based teaching and learning has kindled the interest of the participants as well as the teachers in teaching and learning writing skills. The study recommends the implementation of CALL- a technology -based teaching and learning for the other three skills in English as a second language.
Keywords: ESL, writing skills, tertiary level, traditional mode and technology-based CALL.
