In this paper, we successfully demonstrated a software application on the android platform of mobile phone which allows users to have a quick insight of radiated emission generated based on the image of a printed circuit board (PCB) by using analytical method and image processing. For benchmarking the application, a study on the radiated emission of PCBs with the use of electromagnetic compatibility...
This paper proposes a contactless charging platform with reconfigurable coils which compose a hexagonal coil array complied with wireless power consortium A3 standard. The function of contactless charging platform (CCP) that switches one of them to excite is to avoid the current cancellation phenomenon and to prevent the magnetic field attenuation. The CCP transmits wireless power to the secondary...
Society evolution toward the information and knowledge-based economy made necessary a new and more specific definition of electrical engineering. The paper discusses about new approach of electrical energy systems as power systems microprocessor controlled. From this point of view computer use was integrated in electrical engineering. Some tendency in electrical engineering curricula reform are presented...
With the advances in welfare information technology, Smart Home-based solutions have been gaining importance and becoming accepted as an alternative means of energy-saving based on HEMS — Home Energy Management Systems. This paper defines a decision-making fuzzy technique to be used in a novel architecture (SmartCoM). A fuzzy system has been implemented to provide an efficient energy control method...
This paper introduces the working principle and function of high power DC electronic load. Starting from the main circuit of the electronic load, this paper expounds the structure of electronic load and the idea of subsection load control, discusses the PWM control principle of IGBT, and designs the control algorithm. This load used 32-bit microcontroller STM32F207 as the core processor, with control...
It is important to provide sightseeing information to foreign people to promote tourism industry. However, in order to provide fresh information or intend for new sightseeing contents, we need to pay for the cost of contents updating and system migration. Therefore, we propose “Self-extending Type Open Data Platform” that can take in the tweet of the tourist automatically. This proposed platform has...
A method used for estimating the distance between objects in photographic images is the depth from focus (DFF) method. The method has reportedly been implemented many times using only image-side telecentric optical systems because a change in image magnification becomes a problem due to differences in focus positions. Therefore, there have been no examples of this method having been implemented using...
The purpose of this research is to develop the real-world captioning system to ensure information accessibility for person with hearing impairment. However, switching the visual line between the speaker's face and the caption when one is engaging in conversation may stress the user. In this paper, we propose the real-world captioning system which display the dialog next to the speaker's face using...
A game space is designed and placed by considering the beats (Events or Quests) inducing the behaviors of a player. Beats of FPS game can be divided into three types. It is possible to evaluate the placement of the pieces of space in case of analyzing the visual cognition information obtained by the player depending on each kind of beat. In this paper, players were divided into two groups (Novices...
Spoken dialog systems are presently used widely. However, some users avoid using them because of poor usability and unattractiveness. In this study, we develop a system that captures the user's movement and estimates the user state. This function is incorporated into the existing spoken dialog system to build a multimodal dialog system. In the experiments, the recognition performance of body motion...
This paper proposes the method to recommend music using lyric network. This method corresponding to more than thousands of musics. The authors focus each lyric of the music. Keywords representing music are extracted from its lyric by combining TF-IDF method and principle of discriminant analysis. Lyric network is generated based on extracted keywords. The connection of generated network can recommend...
We propose a reversible data hiding method for embedding secret data in a scaled-up image of a cover image, where the scaled-up image is computed using maximum and minimum filters to achieve higher payload than that of conventional methods based on neighbor mean interpolation. Experimental results show that the proposed method outperforms conventional methods in both data-hiding capacity and image...
As the Internet of Things has emerged, it has become possible to develop applications and services through various types of input / output using things as well as various graphic displays. In view of the development of such interfaces, a distributed user interface (DUI) is emerging in which a plurality of devices are simultaneously used to utilize one application service. In order to activate a DUI-based...
This paper presents a serious game-based system for dance notation training named LabanDance. The system tracks the full body motion via Microsoft Kinect of the user while performing the movement according to the dancing score. The system provides two training modes which a practice mode and an examination mode. The practice mode is designed for users with less knowledge in the notation where movement...
We propose a model that adapts to CNN trained by non-rotated images even for rotated images by evaluating the feature map obtained from the convolution part of CNN. The additional network for rotation angle estimation is able to correct the rotation angle using the feature map in the MNIST data-set. It is possible to cope with the rotation without changing the original network by adding a network...
Captioning lecture speech is very useful for better understanding. However, it takes high cost to do real-time manual captioning or even if we employ automatic speech recognition system and human correction together. In this paper, we propose a method to reduce a cost for human correction as a prerequisite of a framework for captioning using automatic speech recognition system. Specifically, we investigate...
Although cameras are commonly used to achieve customer's attributes in the field of advertising, improving the precision of these consumer features just by imagery has been a great challenge. This paper proposes a new targeted advertising method experimentally accommodated to digital signage systems by using Bluetooth Low Energy (BLE) beacons. The paper provides a design of this new advertising method...
The semiconductor counterfeiting has become a serious problem. Physical Unclonable Function (PUF) is attracted attention as a countermeasure. PUF can generate a unique ID for each device utilizing a variation during manufacturing. However, PUF is vulnerable to modeling attacks. In addition, it is reported that side-channel information allows modeling attacks effectively. To secure the safety of semiconductors,...
We have developed Positioning Capable Vibration Surface Motor System which can be applied to robots and amusement as new type actuator. The Surface Motor System consists of a Mover and a Base-table. The Mover constructs multiple piezoelectric elements and the Base-table is built in vibration sensor. The Mover of this system can move all direction and spin turn without steering mechanism. And position...
In this paper, we propose a wireless battery charging system which the power transfer position can be automatically moved to the optimal charging placement.
