Mobile Learning Readiness among Malaysian Students at Higher Learning Institutes

Abstract: Learning today is beyond the four walls and the Internet environment. The advancement of mobile technology has opened up a myriad of learning opportunities for students in Higher Learning Institutions who need to cope with a complex and demanding learning environment. With this increasing number of mobile phone owners, especially among the student population in Malaysia, educators should look into the possibility of integrating mobile learning into the academic programmes at Institutions of Higher Learning. This paper focuses on basic readiness, skills readiness, psychological readiness and budget readiness of students at two different universities in relation to mobile learning. An online questionnaire survey was used to collect data for this study. The findings revealed that the students are highly familiar with computing skills and they welcome the integration of mobile learning in education. The study also revealed that the students were uncertain as to how much money they needed to spend for the telephone line and Internet line apart from the software and hardware requirements. A discussion on the implications of the findings will also be presented.

Bimodal Character of Cyclone Climatology in the Bay of Bengal Modulated by Monsoon Seasonal Cycle

Abstract: The annual cycle of tropical cyclone (TC) frequency over the Bay of Bengal (BoB) exhibits a notable bimodal character, different from a single peak in other basins. The causes of this peculiar feature were investigated through the diagnosis of a genesis potential index (GPI) with the use of the NCEP Reanalysis I dataset during the period 1981–2009. A methodology was developed to quantitatively assess the relative contributions of four environmental parameters. Different from a conventional view that the seasonal change of vertical shear causes the bimodal feature, it was found that the strengthened vertical shear alone from boreal spring to summer cannot overcome the relative humidity effect. It is the combined effect of vertical shear, vorticity, and SST that leads to the GPI minimum in boreal summer. It is noted that TC frequency in October–November is higher than that in April–May, which is primarily attributed to the difference of mean relative humidity between the two periods. In contrast, mo...

On convergence of homotopy analysis method and its application to fractional integro-differential equations

Abstract: In this paper, we have used the homotopy analysis method (HAM) to obtain approximate solution of fractional integro-differential equations (FIDEs). Convergence of HAM is considered for this kind of equations. Also some examples are given to illustrate the high efficiency and precision of HAM. Keywords: Fractional integro-differential equation, homotopy analysis method, convergence control parameter Quaestiones Mathematicae 36(2013), 93–105

Detection and Processing Techniques of FECG Signal for Fetal Monitoring

Abstract: Fetal electrocardiogram (FECG) signal contains potentially precise information that could assist clinicians in making more appropriate and timely decisions during labor. The ultimate reason for the interest in FECG signal analysis is in clinical diagnosis and biomedical applications. The extraction and detection of the FECG signal from composite abdominal signals with powerful and advance methodologies are becoming very important requirements in fetal monitoring. The purpose of this review paper is to illustrate the various methodologies and developed algorithms on FECG signal detection and analysis to provide efficient and effective ways of understanding the FECG signal and its nature for fetal monitoring. A comparative study has been carried out to show the performance and accuracy of various methods of FECG signal analysis for fetal monitoring. Finally, this paper further focused some of the hardware implementations using electrical signals for monitoring the fetal heart rate. This paper opens up a passage for researchers, physicians, and end users to advocate an excellent understanding of FECG signal and its analysis procedures for fetal heart rate monitoring system.
