Imbalanced classes in multi-classed datasets is one of the most salient hindrances to the accuracy and dependable results of predictive modeling. In predictions, there are always majority and minority classes, and in most cases it is difficult to capture the members of item belonging to the minority classes. This anomaly is traceable to the designs of the predictive algorithms because most algorithms do not factor in the unequal numbers of classes into their designs and implementations. The accu...

Advances in mobile phone technology and the growth of associated networks have been phenomenal over the last decade. Therefore, they have been the focus of much academic research, driven by commercial and end-user demands for increasingly faster technology. The most recent generation of mobile network technology is the fifth generation (5G). 5G networks are expected to launch across the world by 2020 and to work with existing 3G and 4G technologies to provide extreme speed despite being limited ...

Diacritics in Arabic are optional orthographic symbols used to alter the pronunciation of a letter or distinguish between words of similar spellings, which may add or subtract complexity by imposing additional loads on the individual’s information-processing system. In this study, we explored how reading Arabic text with and without diacritical signs (known as ḥarakāt) can influence readers’ brain activation. An electroencephalogram (EEG) recording of 18 subjects was used in this study to assess...

The recent movement to integrate the flipped classroom model into higher education has resulted in significant changes that affected both teaching and learning practices in different ways. After almost a decade of research on the flipped classroom model, different emergent outcomes have been reported in a domain specific context. To gain a comprehensive understanding of the flipped classroom implementation in a university context, a review of the literature on the use of flipped classroom in a u...

Massive open online courses (MOOCs) are among the latest e-learning initiative that have gained a wide popularity among many universities. Student dropout in MOOCs is a major concern in the higher education and policy-making communities. Most student dropout is caused by factors outside the institution’s control. In this study, a multiple-criteria decision-making method was used to identify the core factors and possible causal relationships responsible for the high dropout rate in MOOCs. Twelve ...

This is an exploratory study to model the determinants of actual use of a digital library system. To do so, a research model was developed using Delone and McLean’s information system success model and explained as an empirical study. Data were collected from 978 respondents using a structured questionnaire from four different universities of Malaysia. The findings showed that the quality factors of digital library systems have a strong influence on satisfaction, behavioral intention, and varian...

Wireless Sensor Network is a network of large number of nodes with limited power and computational capabilities. It has the potential of event monitoring in unattended locations where there is a chance of unauthorized access. The work that is presented here identifies and addresses the problem of eavesdropping in the exposed environment of the sensor network, which makes it easy for the adversary to trace the packets to find the originator source node, hence compromising the contextual privacy. ...
