Conventional optical coherence tomography (OCT) systems generally have a limited imaging range within a depth of only 1-2 mm and suffers from unwanted noise such as speckle, ghost or mirror noise. To overcome these limitations, we developed a motorized-stage-based OCT system with an extended imaging range, using a common-path Fourier-domain optical coherence tomography (CP-FD-OCT) configuration. Using this OCT systems, OCT image was obtained from an onion, and their subsurface structure were observed. The result showed that the OCT images obtained using our motorized-stage-based system had a significantly extended imaging range due to its real-time accurate depth tracking. Consequently, the devised CP-FD-OCT systems and algorithms have good potential for the further development of endoscopic OCT for microsurgery.

Sound localization or direction of arrival (DOA) estimation plays a key role in awareness technologies since it can identify the coordinates of an unknown source. In this study, we present a new chip design, which is primarily based on the average magnitude difference function (AMDF), for reducing the hardware area and power consumption. Meanwhile, two novel hardware architectures with the folded architecture and circular buffer are also proposed in order to save unnecessary computation in this system, including short critical paths and simply control units of data access. The experimental results show that our proposed design can successfully enhance the operating frequency and reach higher performance. Furthermore, the accuracy rate of our system can achieve 90% with ±3° errors on average. The chip simulation result displays that the power consumption is approximately 1.3 mW, and the chip area is 0.998 mm2 with 0.18-µm CMOS process.

An efficient case retrieval method and an adjustment strategy are proposed in this paper to build a case-based reasoning (CBR) system for oxygen calculation in Basic Oxygen Furnace (BOF) steelmaking. In the process of case retrieval, the Bayesian rough set technology is adopted to establish the weights of the case attributes. Then, the k nearest neighbors algorithm is implement to retrieval the most similar cases as a reference. The adjustment step executed by mixture of experts model is introduced to make up the gaps between current case's problem attributes and the retrieved case's. Finally, the parameters in mixture of experts model are optimized by Particle Swarm Optimization (PSO) method. Practical production data are used to test the CBR system. Using actual production data converter simulation Results show that proposed system is effective.

Any commercial sites, be it a hotel, a restaurant, or a shop, have to be reached properly by potential customers, and thus an adequate information on the route to the site is important. Route information is represented as a textual description and/or as a map, and in either case, adequate mentions of landmarks, a building or a site that is located in the midst of the route which plays an intermediate marker, are essential. However, human route descriptions or maps based on them may not contain a sufficient number of landmarks that is needed for potential customers, and an automatic determination of necessary landmarks is desirable. In this study, as a preliminary one, we collected more than thousands of route descriptions written by commercial sites, and made an extensive observation to find characteristics of textual route descriptions. Based on the observation, we conducted two experiments: to automatically extract potential landmarks from textual route descriptions and to evaluate the legitimacy of them using a simulative agent. The result indicates that more than half of the textual route descriptions accumulated needs improving, and the extracted potential landmarks can be effectively added for improving existing route descriptions.

In order to reduce power consumption in disk-based storage systems, based on the definition of multiple power states, a lot of efforts focus on power consumption management mechanisms which can be developed to allow system software to control transitions between the power states. But, little work studies energy consumption and performance metrics of I/O systems through the transition probability among different disk modes. In this paper, we define the transition probability mathematically from active mode to idle mode, and propose a novel analytical approach to evaluate energy consumption and performance metrics, i.e., queue length, throughput, response time. Our proposed model might motivate storage researchers to exploit a quick analysis toolkit and give some insights for the design of power-aware storage systems.

This paper focuses on simultaneous piano playing and singing, which is considered to fall in the field of physical skills. The authors previously proposed and implemented an educational approach that makes use of multimedia learning materials and annotated musical scores. In order to clarify the roles of these materials, this paper discusses how learners acquire a physical skill in an educational approach that makes use of only annotated musical scores. The paper reveals that there is a limit to the effectiveness of using only annotated musical scores to acquire such a physical skill, and that multimedia materials are also important for the effective development of physical skills.

Localization is one of key technologies in Internet of Things (IoT) and Wireless Sensor Network (WSN). Various applications have been proposed based on it, e.g. location-aware services. Currently, there are many approaches to locate a person, e.g. based on GPS, RFID, ultrasonic signal etc based on various methods, e.g. TOA, TDOA, AOA, RSSI etc. However, when an earthquake happens, the localization devices in building may be damaged and how to quickly locate the survivors buried in the collapse regional is a key issue, which can save many lives. In the paper, we propose a new method to locate a 3D location of the survivors, i.e. also computing the depth of the buried survivors based on WSN. The method mainly consists of two stages. In the first stage, a draft location of the survivors is computed based on mobile base stations. And then the accurate location of the survivor, i.e. the 3D location, is calculated by an equilateral triangle device with a mobile beacon node.

The three-phase power supply has the advantages of small voltage ripple, balance three-phase load and high output power. It is suitable for application in the large electrostatic precipitators of the sintering machine head and the coal fired boiler. This paper designs the three-phase power supply based on phase sequence self-adaption and redundant spark detection. The winding connection mode of Y-Y and the full-bridge rectification circuit are used. This is beneficial to the energy saving, and the energy saving effect is also analyzed. In addition, the three-phase intermittent control is realized. The comparative experiments of voltage boosting between the three-phase power supply and the single-phase power supply demonstrate that the proposed design is effective.

Nowadays the detection in space environment is definitely a hot spot in the whole world. Developing the technique of multiple materials detection makes great sense. In this paper, we propose an algorithm for spatial multiple materials detection in hyperspectral images. The detection problem is a semi-blind signal extraction problem. As the prior knowledge, the spectra of target materials are known in advance. The proposed detection algorithm, multiple materials detector (MMD), exploits spectral information exclusively to make decisions by considering that the type of each pixel contains the interesting materials or not, which is a semi-blind signal extraction method. With this method, after single time detection of a hyperspectral image, the multiple materials spectra input before could be exactly detected. Compared with classical detection methods, the proposed detection method has three superiorities. Firstly, it functions well when there are various kinds of interesting materials needing to be detected. Secondly, because of using regularization items the algorithm is robust in spectral variability and noise. Lastly, no matter how the interesting materials distribute in the hyperspectral image, it works steadily. Experimental results based on a set of hyperspectral images of Hubble Space Telescope prove the effectiveness of the MMD algorithm.
