A Wireless Internet-access Mesh NETwork (WIM-NET) provides the scalable and reliable internet access through the multiple access points (APs) and wireless relay communications. In particular, by redundantly deploying APs in the network field, the WIMNET becomes robust to the link or AP failure. However, these redundant APs increase the power consumption, and thus the number of active APs should be...
The User-PC computing system (UPC) is a technology of realizing a parallel computing environment using idling computing resources (CPU cycles) in Personal Computers (PCs) of members in the same organization or group such as a laboratory in a university and a section in a company. UPC can resolve drawbacks in the registration of computing projects, the reliability of computing results, and the continuity...
This paper proposes an ontology-assisted information retrieval system for folk implements of Tadami in Fukushima Prefecture. The proposed system is capable of responding to a cross-search by classifying the folk implements by inferences based on the ontology.
This paper summarizes some of the recent research work in visual based ambient assisted living carried out in Centre for Digital Home, Multimedia University. In particular, this paper will focus on detecting dining activities at home with the use of the conventional RGB camera and Microsoft Kinect. According to the best of our understanding, little work has been reported in the literature on identifying...
This paper presents a vision-based landing system concept which could be implemented in a small UAV (Unmanned Aerial Vehicle). Vision-based object detection provides object position information of objects such as pedestrian or road, and those detection methods can also provide precise position during the landing stage of aircraft. Besides, the take off weight of a small UAV should be light in order...
This paper presents the performance evaluations of GMP-based applications on Web-based Volunteer Computing (VC) systems. Web-based VC is expected to gather many volunteer participants (workers) by allowing workers to execute a computation program (job) on Web browsers. On the other hand, the job execution performance on workers degraded because jobs are executed on Web browsers. To reveal the actual...
One of the hardest parts of controlling asthma is making sure patients are getting the right does of medicine through their inhaler based on doctor's instructions. However, the patients, especially children, frequently miss doses or even forget to use it. In this study, our proposed electronic dose counter directly attached to pressurized metered dose inhaler without modification original inhaler...
Peer-to-peer system is a promising solution to manage a large amount of data, but similarity search on peer-to-peer network with a restricted small number of messages is a challenging problem. Existing methods that can perform similarity search work only with low-dimensional data. We propose a method to transform the very high-dimensional data into low-dimensional vectors in order to perform similarity...
In this research, we propose the evaluation scheme of interconnection network of Network on Chip (NoC) by the approach based on probability. In this paper, we focus the multistage network for simplify, and carry out the communication performance analysis on the single flit communication. As the result, the result of flit-level simulation and probability model simulation became almost same. As future...
An innovative method for blast furnace falling materials trajectories measurement using a laser scanner is presented in this paper. The surface profiles of the falling materials delivered from the rotary chute at various titled angle in the filling operation of the blast furnace in China Steel Corporation (CSC) were digitized during the course of burden discharge. Based on the rigid body transformation...
A voltage reference with low temperature coefficient (TC), multipliable outputs and low power consumption is presented in this paper. The proposed reference circuit operating with all transistors biased in the subthreshold region, provides reference voltage of 342 mV. The outputs also can be multipliable to two or three, such as 684 and 1025 mV which is dependence on the requirement of system and...
The purpose of this paper is to embed information on codes when using search-order coding (SOC) to compress index table. The proposed method reassigned the shorter indicators to the indices that can be transformed to SOC codes and those that can not be transformed are assigned by the other indicators. If the cover image is a smooth image, the proposed method can significantly reduce the size of compression...
We propose a received signal strength (RSS) based energy-efficient positioning approach for cellular networks with unknown path loss exponent (PLE). A low-complexity searching algorithm is proposed for PLE estimation and a low-complexity lateration algorithm is proposed to provide the searching criteria. Simulation results show that the proposed positioning method achieves an accuracy similar to that...
A real-time handheld indoor positioning device is developed, featuring 2 novel perfectly complementary positioning methods: 1) RFID Heron-bilateration location estimation, based on external RFID infrastructure, and 2) IMU angular-driven navigation reckoning, based on internal IMU module. At first, 2 or multiples of 2 active RFID tags as infrastructure landmarks are deployed along the surrounding walls...
In Wireless Sensor Networks (WSNs), because sensor nodes do not equip with tamper resistance hardwares, they are vulnerable to the capture and compromise performed by the adversary. By launching the node replication attack, the adversary can place the replicas of captured sensor nodes back into the sensor networks so as to eavesdrop the transmitted messages or compromise the functionality of the network...
In recent years, with the advances in short range communication technology, vehicles are able to communicate with each other (Vehicle-to-Vehicle, V2V) and with the Roadside (Vehicle-to-Roadside, V2R) through dedicated short range communications (DSRC) and are referred to as connected vehicles. In V2R scenario, we design and implement a Traffic Signal Control System (TSCS) for use in real-life IEEE...
In this paper, we propose an algorithm to compute time-dependent Fourier transform (TDFT) with generalized triangular window. The algorithm recursively computes the TDFT at arbitrary frequency with integrated triangular windowing. A common way to compute TDFT with window is to firstly multiply the input data by the window function and then carry out the TDFT on the windowed data. In this paper, we...
Recommender systems, which recommend products, content, or learning resource to users, have become an important issue and received a lot of study. Existing recommender systems utilize different knowledge source to profile users, but in some application fields, such as retailer, obtaining such source can be different. In this paper, we propose a facial recognition integrated recommender system to deal...
This work proposes an automatic recognition system for recognizing audio events. First, an audio signal is converted into a spectrogram by short time Fourier transform. The acoustic background noises in the spectrogram are reduced by box filtering. The contrast of the spectrogram is then enhanced by VAR operation. With the enhanced spectrogram, this work further proposes a novel dynamic local binary...
