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...

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...

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...

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...

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...

Identifying the key determinants of Michinoeki and assessing its impact on efficiency is considered as an urgent issue. Accordingly, this paper proposed a new approach to calculate the efficiency using DEA model after determining the significant factors using a regression model. The data were collected...

Image-based geometric measurement is getting more attention in machine vision field due to its contact-less and low-cost characteristics. Here the measurement of single image with the rectangular structure is studied, in which only one side length of the rectangle is known, and the coordinates of points...

A miniature precision glass encapsulated electrical connectors introduced by glass powder and metal wires through a special complicated process. Aiming at the porosity defects on the surface, a defect detection algorithm propose based on threshold segmentation and feature extraction. Pre-operation, global...
