Layered approach in energy-efficient information technology (IT) classroom design

Abstract

Designing an energy-efficient IT classroom has not been straightforward due to the scattered recommended practices that involve different aspects. Some related aspects have not even been explored and need to be included - to increase the level of power saving and flexibility in implementation. Thus, a comprehensive layered approach or method is designed by this paper. It involves four (4) layers that represent different aspects of an IT classroom that can be made efficient in terms of energy consumption, namely hardware, platform, middleware, and application layers. Each layer is autonomous and hence can be implemented flexibly, subject to the bespoke feasibility of the use case. The proposed method is also expected to be future-proof and expandable due to its catering to both hardware and software-based optimizations. Such guidance is also crucial for the ongoing Industrial Revolution (IR) 4.0 and soon-to-be-established IR 5.0, where smart cities worldwide would be required to be ener.....

Assessing Malaysia’s internet of things (IoT) readiness based on CREATE-IoT key performance indicators

Okta Nurika

Abstract

The current nationwide deployment of Internet of Things (IoT) in Malaysia has never been assessed nor benchmarked against any Key Performance Indicators (KPIs). A proven IoT assessment standard called CREATE-IoT has successfully driven IoT projects in European countries, and it is hence used as a benchmarking tool in this research. The assessment that includes both technical and business perspectives concludes that 42 out of 50 KPIs (84%) in Malaysia are in the advanced state. Malaysia is thus rated as an IoT-ready country. However, rooms for improvement exist in the scopes of providing expected duration for completing an IoT service transaction to predict the level of customer satisfaction when using the service – and the ability to produce IoT sensors and devices locally to have sustainable, scalable, and economical continuous IoT deployments. © 2024, Semarak Ilmu Publishing.

Stress detection and mitigation through discovery of optimal lecture delivery method for STEM-enrolled university students

Okta Nurika

Abstract

The high availability of technology-related jobs is currently not fulfilled by enough supply of technology graduates, specifically the ones coming from science, technology, engineering, and mathematics (STEM) courses. This is related to the low enrolment rate of STEM-based courses at Universities. The notion that STEM subjects are intense and difficult to pass could be the reason of such phenomena. This research experimented different lecture delivery methods comprising of different seating arrangements, inclusion or exclusion of break, group size, and room size to investigate the generated levels of stress among STEM students, so that the method that would induce minimum stress could be discovered. The analysis of the generated heart rates as stress indication concludes that the level of difficulty of STEM subject’s topic is the one that most affected students’ level of stress, while inclusion of break during class is imperious to destress students. Class arrangement with far seat.....

Campus grid deployment with automation

Nurika, Okta

Abstract

Campus grid is a feasible deployment of grid computing since campus environment is equally controlled and the managerial permission is simpler than any other industries. The usability of grid computing is also potentially high, because of the numerous demands from students or researchers in need of high-end computational power and data storage. However, automated efficient way of campus grid platform deployment has never been disclosed, therefore we propose a methodology to deploy a campus grid with automation based on the desktop-grid architecture. Some related issues and challenges that are currently being addressed, with improvements further to be explored, are presented in this paper. Large scale campus grid deployment in this campus involving multiple computer labs and hundreds of computers in total was accomplished, by combining both automation scripts and manual intervention. The chosen campus grid software system is Berkeley Open Infrastructure for Network Computing (BOINC). Th.....

Benchmarking Australia’s qualitative internet of things (IoT) extensiveness

Okta Nurika

Abstract

Australia as one of the most referred industrial countries in the world is currently going through national scale Industrial Revolution 4.0 (IR4.0) that is driven by Internet of Things (IoT). The technical deployment and business model have been devised in a roadmap, which mainly covers historically successful use cases (industrial solutions) in Australia – hence giving it the globally renown sophisticated reputation with international technology companies making up the IoT business along with local enterprises and start-ups. However, this roadmap has never been assessed and given the importance of Australia as a point of worldwide technological reference, it is crucial to qualitatively benchmark it against a tested standard. In this paper, the roadmap would be measured against the proven Key Performance Indicators (KPIs) specified in enhanced CREATE-IoT standard. The original CREATE-IoT successfully assessed smart cities in European countries, while its enhanced version has plausibl.....
