Project information system for Putrajaya Holdings Sdn Bhd

Independent information banks produces different mindset and values within the respective divisions causing misunderstanding, incoherence, and incompatibility in group communication, which results in unsound decisions that are not mutually beneficial to the group. A feasibility study was done and has shown the requirements to implement a system called Project Information System (PIS). It is designed for Putrajaya Holdings Sdn Bhd (PJH), a mega project developer for Putrajaya City (the Administrative Center for the Government of Malaysia) to facilitate an effectual management of an organization by providing centralized access from a single source to the required information. The objective of the project is to give direct benefit for the company such as fast retrieval of information, enhances decision-making and tactical planning whilst avoiding confusion and/or ambiguous situation where misinterpretation could be costly both in terms of monetary and time factors. With currently available and more innovative technology, the organization uses IS/IT to realign its business activities to achieve performance breakthrough. In this way, organization and its environment, workers and external third parties who involve in PJH projects, stand to benefit by having real time and online reference to project information at their fingertips. PIS, a client/server and web-based system, is implemented using open source solutions that are MySQL as the database, and PHP as the programming language. Waterfall approach was chosen for the system implementation. The PIS system consists of five modules and was developed in phases. Therefore, PIS is a necessity as a tool to provide a competitive edge to Putrajaya Holdings in controlling its projects, and improve communications within the group and its environment (contractor and consultant)

Facile preparation of carbon quantum dots from biochar via microwave–assisted hydrothermal synthesis

Carbon quantum dots (CQD) were successfully synthesized using microwave-assisted hydrothermal method using empty fruit bunch (EFB) biochar as the carbon precursor. Effect of temperature (60°C – 130°C), solvent concentration (0.1- 0.5 mole fraction of IPA) and reaction time (5 – 30 minutes) were investigated on CQD yield (%). The optimum process gives the highest yield and it is about 15.22% at 100°C with 0.1 mole fraction and in just 5 minutes. Material characterisations confirm the formation of CQD where microscopy images showed an average size distribution of 4.5 nm. Chemical structure has shown the presence of oxygenic functional groups such as hydroxyl, carbonyl/carboxyl at 3270 cm-1 and 1640 cm-1 respectively. The presence of these oxygenic functional groups are also supported by X-ray Photoelectron Spectroscopy analysis where C–C/C=C (284.6 eV), C-O (285.5 eV), C=O (286.5 eV) and COOH (288.1 eV). To complement experimental data, density functional theory (DFT) calculations were carried out at 6-31G(d) basis set and a comparison of three exchange correlation functions such as B3LYP, CAM-B3LYP and wB97XD. These functionals are able to calculate the ground state molecular structure of CQD where the subsequent frequency analyses for each functionals give no imaginary frequencies. The highest occupied molecular orbital and lowest unoccupied molecular orbital (HOMO-LUMO) gap obtained from 6– 31G(d) with Becke’s three parameter with Lee–Yang–Parr (B3LYP) is 6.381 eV and is closer to experimental band gap of 3.2 eV compared to Coulomb attenuating method with Becke’s three parameter with Lee– Yang–Parr (CAM–B3LYP) and wB97XD. In conclusion, a facile preparation of CQD from EFB biochar was successfully obtained from microwave-assisted hydrothermal process. The process was efficient, rapid, cost-effective and eco-friendly

The Role of Casting Methods in Preserving Traditional Martial Arts through Motion Capture Technology

This paper explores the integration of casting methods, specifically audition, within the theoretical framework of motion capture technology for the preservation and safeguarding of traditional martial arts. Traditional martial arts performances hold immense cultural value, and their accurate representation is crucial to ensure the preservation of intangible cultural heritage. However, the use of motion capture technology introduces risks, such as the potential loss of critical metadata, which can lead to inaccuracies and undermine the reliability of the captured data. To mitigate this risk, casting becomes an indispensable measure to ensure precise and dependable motion capture. By integrating casting techniques, such as engaging in traditional martial arts performances and including detailed descriptions of movements in the metadata, motion capture practitioners can enhance the preservation of cultural heritage. This research highlights the significance of casting techniques in motion capture practices for the faithful portrayal of traditional martial arts performances, capturing their nuances, and providing insights into their historical and cultural contexts. Acknowledging the importance of casting in motion capture practices is vital to guarantee the preservation and safeguarding of traditional martial arts for future generations

Acid-free hydrothermal-extraction and molecular structure of carbon quantum dots derived from empty fruit bunch biochar

Carbon quantum dots (CQD) have great potential to be used in various applications due to their unique electrical and optical properties. Herein, a facile, green and eco-friendly hydrothermal method for the preparation of carbon quantum dots was achieved using empty fruit bunch (EFB) biochar as a renewable and abundant carbon source. In the current study, the role of the hydrothermal process was observed and studied by comparing the morphology and optical characteristics of CQD obtained from EFB biochar. Interestingly, based on the high-resolution transmission electron microscopy (HRTEM) result, a considerably similar carbon quantum dots structure can be observed for the EFB biochar sample, showing the similar size and distribution of CQD. To further discuss the extraction of CQD from EFB biochar, a mechanism based on hydrothermal-induced extraction of CQD is proposed. The optimal structure of CQD deduced by density functional theory (DFT) in energy and dipole momentum was about 2057.4905 Hatree and 18.1699 Debye, respectively. This study presents a practical experimental approach in elucidating the molecular structure of photoluminescence CQD based on the Fourier transform infrared (FTIR) spectroscopy, X-ray photoelectron spectroscopy (XPS) and transmission electron microscopy (TEM) results
