The need of improving the education quality is insparable from the strategic role of teachers. One potential solution to develop the teachers quality is the use of information and communication technologies (ICTs). In this paper, we propose a Digital Learning - Lesson Study (DL-LS) that is an implementation of Lesson Study - a teacher learning method(More)
There is no doubt that the need of improving the quality of primary schools particularly in rural areas is very urgent for government. One of the most promising solution is through utilization of Information and Communication Technologies (ICTs). In this paper we present our effort and work in improving the quality of primary school teachers and the(More)
Information Technology in business is significant. This study tries to trace the relationship between IT value and firm performance. The methodology of the study is analyzing some variables forming the relationship of IT value to firm performance based on the Resource-Based View Theory. The analysis results in IT Value Model using Variance-Based Structural(More)
The paper describes a Field Programmable Gate Array (FPGA)-based lossless data compression coprocessor using implementing a compression method developed by Rice. We have implemented the Rice code (both encoder and decoder) for 8 bit/sample data on an FPGA Xilinx XC4005. The code has been designed to be optimal on 1.5 < H < 7.5 bits/sample,(More)
Distributed hash tables (DHTs) with O(1) lookup performance strive to propagate membership changes through efficient distribution mechanism to allow each node in the peer-to-peer network maintains accurate routing tables with complete membership information. We present UnoHop, an efficient DHT algorithm with O(1) lookup performance. UnoHop uses an efficient(More)
In this paper, we propose an automatic segmentation and detection of heart sound components (S1, S2, S3 and S4) which incorporates Empirical Mode Decomposition (EMD) denoising, autocorrelation-based cardiac cycle calculation, Shannon energy envelope extraction, first derivative peak and boundary detection, and real peak selection using Heron's formula. The(More)
The objective of this research is to develop a rapid prototyping of DSP system, allowing design and implementation of real-time DSP algorithms on a single-chip system. The research and development method includes specifications, analysis, design, architecture, implementation, testing, and integration. We use a product-service-value system (PSV-S) approach(More)
