It is difficult to generalize and accumulate experiences of system development as methodologies for building meta-learning support systems because the meaning of “meta-cognition” is vague. Therefore, the importance of a model oriented system development approach has been recognized. It contributes to systematic refinement of each learning system by iterating a loop that building a model that can clarify design rationale of the system, developing and evaluating each learning system according to the model, and revising the model based on it. Moreover we can accumulate knowledge on meta-learning system development based on it. Thus, we adopt a model-oriented approach: (i) we adopt Kayashima's computational model as a basis to build a meta-learning task model and we add two factors of difficulties in performing meta-learning activities, (ii) we conceptualize five concepts for building meta-learning scheme that clarifies means to remove/ eliminate the factors of difficulties; then (iii) we embed support functions to facilitate meta-learning processes based on the model. This constitutes a promising approach not only for building learning support systems but also for accumulating/ revising knowledge on the system development. In this paper, we firstly describe the philosophy of our research to elucidate our model-oriented approach. Secondly, we present a meta-learning process model as a basis for understanding meta-learning tasks and what factors of difficulty exist in performing meta-learning activities. Thirdly, we explain our conceptualizations as a basis to design sophisticated meta-learning scheme to prompt learners' meta-learning processes. Fourthly, we integrate a meta-learning process model and conceptualizations so that we design our meta-learning scheme based on the deep understanding of meta-learning processes. Then, we present our presentation-based meta-learning scheme designed based on the model and clarify the design rationale of our system based on the model. Finally, we describe the usefulness of the model by characterizing other meta-cognition support schemes.

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.

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.

Opportunities and needs are increasing to input Japanese sentences on mobile phones since performance of mobile phones is improving. Applications like E-mail, Web search and so on are widely used on mobile phones now. We need to input Japanese sentences using only 12 keys on mobile phones. We have proposed a method to input Japanese sentences on mobile phones quickly and easily. We call this method Number-Kanji translation method. The number-string inputted by a user is translated into string to Kana-string is a one-to-many mapping. Therefore, it is difficult to translate a number-string into the correct sentence intended by the user. The proposed context-aware mapping method is able to disambiguate a number-string by artificial neural network (ANN). The system is able to translate number-segments into the intended words because the system becomes aware of the correspondence of number-segments with Japanese words through learning by ANN. The system does not need a dictionary. We also show the effectiveness of our proposed method by the result of the evaluation experiment.

In this work, we propose a new method for human body accurate detection in a static image with multiscale superpixels. The main contribution of this work is as follows: (1) A new framework for human body accurate detection using multiscale superpixels and classifier with autothreshold is proposed. (2) Some effective constraints for human body detection are given. Experimental results show the framework can accurately detect the human body in most situations. The dataset we use is a collection of photos of humans, varying in pose and clothing with complex backgrounds.

This paper presents a novel iterative greedy algorithm for Distributed Compressed Sensing (DCS) scenario based on backtracking technique, which is denoted by DCS-SAMP. The algorithm can reconstruct several input signals simultaneously, even when the measurements are contaminated with noise and without any prior information of their sparseness. It can provide a fast runtime while also offers comparably theoretical guarantees as the best optimization-based approach. This makes it as a promising candidate for many practical applications,such as Tele-Health or Telemedicine. Numerical experiments are performed to demonstrate the validity and high performance of the proposed DCS-SAMP algorithm for multichannel biomedical signals.

With the advent of Internet of Things (IoT), more and more smart things automatically engage in people's daily life by various means as they are becoming capable of computation and communication. Both challenges and opportunities are posed. To exploit the potential of IoT, different concepts from various points of view have been explored. One of the IoT developing trend is so-called Ambient Intelligence (AI), which refers to things that are sensitive and responsive to the presence of other things and people. The things shall be aware of ambient environments (e.g., other things or people) and take actions accordingly. However, complicated configuration of AI hinders the popularity of IoT. To tackle this problem, we advocate applying the highly abstract concept of “IF-THEN” as the front-end of AI in IoT. To realize such a concept, we present a preliminary design in this paper, including issues of the architecture design, the uniformly understandable language and function assembly.

The nonlocal-means (NLM) is a powerful method for image denoising which takes advantage of the redundancy of similar patches in the image. The steering kernel regression is a non-parametric estimation for image restoration that develops a data-adapted steering kernel based on local orientation estimate. In this paper, a steering kernel based nonlocal-means filter (SK-NLM) has been developed which not only exploits the self-similarity of the image, but also considering the structural information by the steering kernel. Experimental results show that the proposed method effectively improve the PSNR while preserving local structures.

Cognitive radio system (CRS) is a disruptive technology targeting very high spectral efficiency. This paper presents an overview of CRS and summarizes the related regulation and standardization status. We point out some key research challenges, especially implementation challenges of cognitive radio and deduce research directions in CRS. Despite numerous challenges, the timeframe for the success of CRS is more linked to the economical and business model than real technological issues.

Passive Dynamic Walker can descend a shallow slope only using an initial velocity and the gravity. It has good energy efficiency because it does not require any actuator. However, it has been known that it cannot walk on a steep slope. Controlled walking models, called “semi-passive dynamic walkers” are considered in this research to accomplish stable walking on the steep slope. The experimental model is defined as the compass shaped model which has control to the hip joint and ankle joint. Three different controlled models are tested to investigate the characteristics of walking. As the result the controlled model accomplishes steep slope walking and it has some robustness to the angle of the slope if sufficient torque is added.
