Lessons Learned through Joint Research Projects on e-Learning in Asian Areas(Session 1: Creating and Implementing Distance Learning Programs Across Borders,Networks without Borders : Towards Cross-Cultural Learning Communities)

Information Communication Technologies (ICTs) are driven forces for evolutional changes in higher education at universities and vocational education in industries. This paper describes challenges in e-Learning at Waseda University, especially collaborative works on e-Learning with people in Asian countries and reports some of lessons learned through these activities

A Chain Oriented Data Collection Protocol for Energy-Aware and Delay-Constrained WSN

Energy awareness plays an important role in developing routing protocol for the battery powered wireless sensor networks. As the replacement of the battery is often unfeasible in practical situations, we present here an optimal solution for the maximum utilization of precious available energy at the same time trying to minimize the latency in data delivery. We propose to form hierarchical chains with deployed sensors to collect information from a target field where data get fused at every node level before transmitted finally. Our protocol utilizes the higher energy nodes for more frequent long distance transmissions so that the energy expenditure become even between all nodes in the network irrespective of their physical locations. It has been found in our simulation that this protocol outperforms other hierarchical protocols like LEACH and PEGASIS in both the cases of energy consumption and time requirements respectively. It has been also found that the overall lifetime of the sensor network also increases in our protocol

Grapheme Cluster Segmentation Tool for Myanmar Text Based on Positional Prediction Text Input Concept

We present the grapheme cluster segmentation tool for Myanmar text based on our proposed Positional Prediction text input concept. Motivation of this research is to develop the Positional Prediction database of Myanmar consonants from the existing Myanmar electronic documents such as PDF e-books, Microsoft Word documents. In this paper, we introduce segmentation rule, implementation process of Positional Prediction combination pattern segmentation and character segmentation. We also present difficulties of encoding conversion from old ASCII based font to Unicode font, developing process and initial study results with the content of a Myanmar e-book of 62 pages. This grapheme cluster segmentation approach is not only useful for creating Positional Prediction database but also applicable for statistical analysis on distributions of characters and Positional Prediction patterns of Myanmar languag

Managing Blackout in Off-grid Communities through Time Based Energy Allocation Model

In recent years, the smart grid hasoccupied the area of power and gridmanagement research and indeed a lot ofbrilliant works have been done. Nevertheless,most of these works have been designed only forthe improvement of traditional grids and little ornothing has been designed to address the needsof people living in off grid communities thatimbibe the use of stand-alone renewable energysolutions which are not properly managed andresults in blackouts more often than it solves theelectricity challenges. Our proposed solution isdesigned to meet with the needs of users whoseenergy consumer patterns are often time bound.We look into the sub parameters of time andState of Charge (SoC) of batteries to allocateenergy resources to devices
