Learning with seorius game based virtual environments provide immersive and motivation. One aspect of learning is evaluation. But evaluation provides anxiety on the learner, as question that is too difficult. In this paper will describe how to generate questions in evaluation(quiz) based on bloom taxonomy with composition 25:50:25 for the types of questions C1, C2, and C3. The question generation...
Mobile agent brings new concept on programming, especially on distributed computing paradigm. It attracts great interest because of its mobility, autonomy and persistence. But it also brings security issues i.e. insecure networks, malicious agents, malicious hosts and malicious users. One most difficult issues is protecting mobile agent from malicious host because mobile agent execute its code on...
This paper presents the performance analysis and comparison of three denosing methods for heart sound signal based on wavelet transform (WT), total variation (TV), and empirical mode decomposition (EMD). Extensive simulations are performed using normal and abnormal heart sound data and the performance is evaluated in terms of signal-to-noise ratio (SNR), root mean square error (RMSE), and percent...
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 proposed method is evaluated on synthetic...
Virtual prototyping is natural in developing DSP systems using a product-service-value system (PSV-S) approach. Our DSP virtual prototyping approach consists of four development phases: (1) a generic DSP system, (2) a functional DSP system, (3) an architectural DSP system, and (4) a real-time DSP system. Such an approach results in a more comprehensive approach in DSP system development. The paper...
There are many studies regarding the IT (Information Technology) value, however until now there are not yet any researches discussing an exact method to estimate this value. Accordingly, this study tries to present a methodology to assess this value using both qualitative and quantitative methods. The offered methodology addresses valuation of IT by means of IT value definition approach as a division...
This paper describes a spreadsheet platform for learning signal processing called SignalSheets. SignalSheets consists of sections, each represents a signal transformation from input to output. In this paper, we use SignalSheets to explain how to estimate spectrum of an input signal using fast Fourier transform (FFT) of Appoints. It starts with puting the input signal into an input section. If the...
This research examines how to develop a Knowledge Management System (KMS) which implements the question-based method in lesson study. Lesson study activity which has been running were not documented well, whereas its benefits are very good to encourage teachers' quality in learning activities. Question-based method applied is evaluation / assessment process that aims to engage teachers to contribute...
This paper describes a spreadsheet platform for learning signal processing called SignalSheets. SignalSheets consists of sections, each represents a signal transformation from input to output. We use SignalSheets to explain a design process of a finite impulse response (FIR) low pass filter. It starts with a design assignment describing LPF specifications. We assume a FIR linear constant coefficient...
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 to develop a computational heavy speech compression...
This research involves the activities of lesson study that has been running for about five years ago by a Teacher Learning Communities (KGB) in Subang — Cianjur, West Java. These activities consist of Planning (Plan), Implementation (Do) and Reflection(See). After process See is finished, Mobile Learning Lesson Study (MLLS) then built as a learning system based on mobile devices in order to support...
Lesson study is a model of professional development of teacher from Japan is called Jugyou Kenkyu, means Jugyou is lesson or learning and Kenkyu is study or research or assessment. Lesson study consists of three phases that continuous cycle, there is plan, do, and see. On this research, lesson study is applied using instructional design. By using instructional design can help designer guard against...
Voice over IP (VoIP) is increasingly replacing fixed line telephone systems globally due to lower cost, call quality improvement. More and more application improvement and Video communication is emerging as an alternative to traditional public communication. End-to-end QoS for large Enterprise consists of three general areas: cutomer premises QoS ("LAN QoS"), Service Provider (SP) core network...
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 through the study of teaching and learning process...
The objective of this research is to study the performance of a high quality speech compression in real-time on a single-chip system. Based on voice over Internet protocol (VoIP) requirements, we have decided to implement a high quality speech coding (with signal-to-noise ratio, SNR of more than 10 dB), at a low bit rate of 8 kbit/s or less. The coder must have delay not more than 100 ms. The development...
Designs of smart environments for smart living require descriptions of a relevant reality in which the smart environments take place. This paper attempts to describe theoretically a suitable virtual reality upon which a designer can engineer smart environments using information and communication technology (ICT). In this first part, the paper starts with a transportation metaphor, and proceeds to...
This paper describes a computing model of a product-service-value system (PSV-S), especially its performance and behavioral models. We have developed PSV-S concepts as an abstraction of engineering solutions and processes. In this paper, we develop a model of a practical PSV-S with an emphasis on value creation for itself as well as for four other sources. This requires exchanges among five currencies...
Engineering smart environments needs a set of requirements of smart living and a generic smart environment platform. This paper describes conceptual requirements using terms developed in our previously described transportation metaphor. In particular, we have limited the smart living to be generating wealth in forms of product-service-value systems (PSV-S). It further uses an engine paradigm to create...
For supporting multimedia Quality of Service (QoS) over wireless network, IEEE 802.11e introduced Enhanced Distribution Channel Access (EDCA) scheme to divide each service category application in the form of access. However, this mechanism does not guarantee the QoS on the high network traffic. This research aims to apply Adaptive Admission Control (AAC) based on Adaptive Framework to resolve the...
The paper describes a new concept of smart engineering using PSV-S concepts for wealth creation. It expands engineering coverage from traditional product developments, service engineering, to value creations. It describes a PSV-S to be an engine driving forces and value exchanges. The paper also argues that PSV-Ss should be the output of any modern engineering. Furthermore, it proposes to use a special...
