Missing values are often a major problem in many scientific fields of environmental research, leading to prediction inaccuracy and biased analysis results. This study compares the performance of existing Empirical Orthogonal Functions (EOF) based imputation methods. The EOF mean centred approach (EOF-mean) with several proposed EOF based methods, w...

Missing values often occur in many data sets of various research areas. This has been recognized as data quality problem because missing values could affect the performance of analysis results. To overcome the problem, the incomplete data set need to be treated or replaced using imputation method. Thus, exploring missing values pattern must be cond...

The variety of food including food choice and preference, food production, dietary intake and other have been done by previous researchers. Other than that, the implementation of visualization techniques has been used in visualizing the result and its findings regarding on food-related research. However, there is lack of understanding towards food-...

Data visualization is used to analyze the patterns and trends of data, including budget distributions, business analytics and so forth in a form of diagrams, charts, graphs and so on. In Malaysia, the budget is still in the form of a speech text and infographics. In the previous study, a treemap visualization technique is used to visualize the Mala...

This paper investigates the suitable position and number of pooling layers in Convolutional Neural Network (CNN) for script recognition from scene images. A common practice of CNN for object recognition is to position a convolve layer alternately with a pooling layer followed by a few layers of fully connected layers. We re-evaluate this basic prin...

Data visualization is an alternative representation to analyze complex data. It eases the viewers to identify the trends and patterns. Based on the previous literature, some countries such as United States, United Kingdom, Australia, and India have used data visualization to represent their election data. However, Malaysia election data was reporte...

Solar energy supplies pure environmental-friendly and limitless energy resource for human. Although the cost of solar panels has declined rapidly, technology gaps still exist for achieving cost-effective scalable deployment combined with storage technologies to provide reliable, dispatchable energy. However, it is difficult to analyze a solar data,...

For decades, quality of work life has always been associated with human wellbeing, which eventually results in happiness. This concept of happiness consistently correlated with increase in business performance, health, marital success, friendship, longevity, creativity, profit and promotion. Thus, a survey work through happiness index assessments m...

e-Technology has enabled users from remote locations to collaborate together virtually and involve in e-activities to reach their common goals. The virtual environment is commonly known as Networked Collaborative Virtual Environment. It is a challenge to manage these remote located users since they are diverse in term of language, culture, and skil...

Data visualization is an efficient method to analyze complex data. It eases the reader to identify data patterns. Based on the previous studies, countries such as United States, China, Russian, and Philippines have used data visualization method to present their budgets. However, Malaysia Budget is still reported in speech text, which is difficult...

Discovering factors and relationships that affect the temperature of photovoltaic module panel is vital to solar energy based research in an attempt to generate green energy effectively. Despite the availability of visualization tools that assist in the discovery, they are not dedicated. They require some efforts, time and certain level of skills t...

In computer supported cooperative work (CSCW), users work together from remote locations where each of them performs specific roles. However, their roles are dynamic and they change their roles more often as compare to co-located environments. The process of changing roles is known as role transition. Role transition process basically determines wh...

In networked collaborative virtual environment, users from dispersed locations can work as a group. Each user holds certain roles along with responsibilities and access to resources. However, the virtual environment is dynamic and users have to change their roles frequently. The process is called role transition and currently it is managed by users...

Role is very crucial in our daily life. People play different roles at different places and times. Their role can change from being staffs at the office, customers at shop, and parents at home. Moreover, people's role influences their motivation level, job satisfaction, peace of mind and security to resources or belongings. Role is vital in network...

Awareness is the sense of what is happening, who is around, what they are doing, what their states of emotion and whether or not they notice you. Social awareness and how they are promoted by digital elements in networked collaborative virtual environment (NCVE) is the main focus of this study. Social awareness is defined as the understanding of a...

This paper presents a comparative study on the usage of digital elements in networked collaborative virtual environments (NCVE). The focus of this study is to explore the characteristic of digital elements that promote social awareness. Social awareness is defined as the understanding of a contextual situation at a present time. In networked collab...

In interactive networked collaborative virtual environment (NCVE), users work in a group to be involved in interactive activities such as game, discussion and learning. However, without having a clearly defined roles and access control of the different level of users, interaction within a virtual environment will not be effectively carried out as t...
