For the purpose of retrieving impressive scenes from lifelog videos based on facial expression recognition, an effective equipment to take facial videos is developed in this paper. the important advantage of this equipment is that it is able to take facial videos without excessive fatigue. In addition, we implemented an emotional scene management system. It provides the functions to store facial videos to a video database and to retrieve and display emotional scenes through Web browsers. In order to measure the retrieval performance of emotional scenes, a retrieval experiment was conducted. It was experimentally shown that about 78.6% of the emotional scenes were retrieved successfully.

this paper proposes a method for evaluating impressions using a space containing impression words. the impression of an object is specified by circling impression words that match the impression. the degree of matching of the impression is expressed by the darkness of the color used to paint the circled area. this proposed method poses few restrictions to users evaluating an impression. Conversely, the semantic differential (SD) method evaluates an impression in a predefined range to enable statistical processing. A prototype system is implemented to evaluate the proposed method, and experimentally compare it with conventional methods, such as the SD method. Finally, it is demonstrated that the proposed method can evaluate aspects that other methods cannot.

In order to avoid the problem of mismatch between the questioner and the respondent, we have conducted impression evaluation experiment and nine factors are obtained as a result. then factor scores of any other statements have been tried to be estimated by using multiple regression analysis from feature values of statements. By adopting syntactic information of statements, word imageability and closing sentence expressions as the feature values, all the factor scores were well estimated. this paper tries to explain the estimation result with major feature values. the explanation is confirmed by comparing the features of the statements having high and low factor scores withthe major features.

this paper uses Postgre SQL, a database management system, in the data management of the similarity retrieval of subsequences of waveforms. By using Postgre SQL, the management of data could become easy, and a multi-dimensional index structure named the R tree could be used. this paper examines the parallel processing of the similarity retrieval by dividing a table into several tables. It is shown that high retrieval performance can easily be obtained by using a high performance computer. It is shown that using Postgre SQL could make the division of a table easy because R tree indexes are automatically constructed.

this paper proposes a method to recommend the relevant information of the document which recorded in the development support systems such as BTS and VCS. We improve a system which we implemented in previous work withthe method proposed in this paper. Our method get a document from the support systems, extract the word, then calculate the feature vector based on the TF-IDF value of each word. In the experiment, we apply the proposal method to the dataset from an open source software projects, and evaluate the recommendation accuracy between the six clustering algorithm. the result of the experiment shows that the proposed method improves the recommendation accuracy compared withthe previous work.

An object-based image processing technique is applied to detect inundated areas using Land sat images. An interoperable Web-based system was developed to conduct the analyses so that redundant steps in Land sat image processing can be effectively eliminated. A review process is used to discover and develop suitable algorithms to automatically detect inundated areas and immediately transfer the results to the Web-based interface. this is a significant improvement over currently available methods for inundation detection systems. the tool is expected to be a practical inundated area detection function and be applicable across wide-reaching areas.

Recently, it becomes common to handle large files in computers. However, we have a difficulty to realize file sharing over networks, especially for large files. the problem is that we have extended the system model designed decades ago based on a stand-alone computer model. Assuming that all files are located in data centers, and nobody accesses them at the sites, we can redesign the file sharing system model for higher access speed and efficient storage resource usage. We designed a global secure file sharing system called Content Espresso. In this paper, we describe the difficulty, the design goal for global secure file sharing system, and our approach for it. Finally, we explain the impact of Content Espresso on network.

distributed constraint optimization problems (DCOP) have attracted attention as a means of resolving distribution problems in multiagent environments. the authors has proposed a multiplex method targeting the improved efficiency of a distributed nondeterministic approximate algorithm for distributed constraint optimization problems. the multiplex method targeting the improved efficiency of a distributed nondeterministic approximate algorithm have been proposed for distributed constraint optimization problems. Since much of the computation time is used to transmit messages, improving efficiency using a multiplex computation of distributed approximate algorithms might be feasible, presuming that the computation time of each node or a small change in message length has no direct impact. Although it is usually impossible to guarantee that the approximation algorithm can obtain the optimal solution, the authors managed to do so, using a theoretically determined multiplex method. In addition, the authors shows the feasibility of an optimal solution attainment rate of 0.99 by an experiment using a distributed Stochastic Search Algorithm.

this paper presents the Content Aware Network designed as one of the Parallel Internets developed on Virtual Infrastructure. the CAN is a post-IP network designed to facilitate access to multimedia content in large scale environment. We introduce the proposed CAN network architecture and discuss mechanisms and algorithms required to assure ubiquitous content access and efficient content delivery. In particular, we propose new content naming and resolution schemes, an effective content source selection algorithm, which optimize resource utilization and the flexible content delivery method. Moreover, we present developed prototype and numerical results illustrating effectiveness of proposed CAN delivery method.
