Sleeping on the wheels due to drowsiness is one of the major causes of death tolls all over the world. The objective of this research article is to classify drowsiness with alertness based on the Electroencephalogram (EEG) signals using spectral and band power features. A publicly available ULg DROZY...

A system is proposed that performs gait analysis of a pedestrian to improve a walk posture and at the same time to prevent a fall. In the system, a user walks with a chest-mounted camera. His/her walking posture is estimated using a pair of images obtained from the camera. Normally it is difficult to...

We construct a Virtual Reality, VR system centered on the tactile sensation. Tactile sensation has a more significant effect on sensibility than audiovisual. Therefore, if tactile sensation and audiovisual sense are combined, we can create “virtual presence” in the VR space. In this system, a user’s...

This paper presents a new Self-repairing Control System (SRCS) for plants with actuator failures. The proposed SRCS uses the well-known Izhikevich spiking neuron model as a fault detector. When the actuator fails, the neuron model is excited and then spikes occur. Thus, counting up spikes makes it possible...
5. Proposal of an Algorithm to Generate VDM++ Specification Based on its Grammar by Using Word Lists Extracted from the Natural Language Specification

The natural language includes ambiguous expressions. Vienna Development Method (VDM) is one of methodology on the formal methods to write the specification without ambiguity. Because VDM++ is written by strict grammar, it is difficult to write a VDM++ specification. This research attempts to generate...
6. Simulation of SPWM Fed Three-phase Induction Motor Drive Mathematical Model Using MATLAB Simulink
Amir Rasyadan, Sazali bin Yaacob, Pranesh Krishnan, Mohamed Rizon, Chun Kit Ang
Pages: 170 - 174
Three-phase induction motors are used in a vast area of applications mainly due to their simplicity, ruggedness and high reliability. With recent advancement in semiconductor technologies, the use of fixed speed induction motor drive is becoming obsolete, majority of the applications now requires inverter-based...

Ocean current refers to the relatively stable flow of the surface water of the ocean in a certain direction, and is the main regulator of the thermal environment on the surface of the earth. At present, the ocean current velocity detection at sea is basically a field measurement by a staff member in...

The paper presents the pilot test of the Moto Tiles Body & Brain Test combined with automatically generated individualized training protocols. The test is performed with seniors (avg. 80 years old) with mild dementia in senior care centers in Roskilde, Denmark. The seniors performed pre- and post-test...

This paper focuses on patterns of innovation and the R&D strategy of automobile companies for technological changes. Tushman and Anderson (1986) pointed out that there are two types of technological changes: incremental technological change and radical technological change. In particular, radical...

The state of the art of mobile robot path planning is composed with global planner and local planner. For example, the global planner majorly establishes a suitable path from a knowing map based on the shortest path. And the local planner which computes the velocity command that includes obstacle clearance...
11. Software Modeling Technique and its Prototype Tool for Behavior of Multiple Objects Using Extended Place/Transition Nets with Attributed Tokens
Tomohiko Takagi, Ryo Kurozumi
Pages: 194 - 198
This paper shows Extended Place/transition Net with Attributed Tokens (EPNAT) and a modeling technique using it in order to address the problem of EPN. In software modeling using EPN, objects of which the software consists need to be defined individually as sub-EPN models, even if they have the same...
12. A Study of Applying Computer-assisted Language Learning to English Course for Junior College Students in Taiwan
Shu-Hua Huang, I-Hsien Liu
Pages: 199 - 203
This study aims to explore the impact of the integration of computer-assisted language learning into traditional face-to-face English course on the learning effectiveness at Junior college in Taiwan. To achieve the above purpose, this study adopts the pre-experimental design with one-group pretest–posttest...
