E investigate the role of nodes when a minimum dominating set (MDS) approach is considered in controlling a network. We present an algorithmic procedure to compute the critical and redundant nodes using the MDS. The theoretical analysis for scale-free networks shows that (1) high-degree nodes tend to be critical nodes and (2) for scaling exponent gamma>2, such probability increases when gamma grows...
Generally inquiries through Web forms and e-mails are increasing. These inquiry texts usually include many informal expressions use of the colloquial style, such as a spoken language, and many omitted words. An omitted word causes the meaning of a sentence to become ambiguous and may make the reader misread and misunderstand the context. In this paper we focus on the frequently omitted noun ``B''...
We have recently proposed a resilient network architecture based on a movable unit. The unit, which we call Movable and Deployable ICT Resource Unit or MDRU, hosts the resources required to offer ICT services. To confirm the effectiveness of the architecture, we develop a prototype MDRU and test bed environment and conduct an evaluation of the architecture. This paper reports the results of concept...
This paper presents a human tracking algorithm based on Particle Filter with Local local descriptors in complex environments such that significant occlusions, motion changes and abrupt motion changes occur. The local descriptors are selected for drastically changing geometric appearances over time. To track a target robustly, we suggested Reliable Appearance Model (RAM) that can deal with the complexity...
The problems of Web data accessibility and navigation for blind users have become an active research field for the past decade. Many techniques have been created to solve them, some are hardware based and others are software based. Yet, the Web is rapidly evolving toward the far-anticipated Semantic Web (SW): a revolutionary vision extending Web information with well-defined meaning so that it becomes...
In this paper we focus on the issue of pervasive applications and service development supporting cultural heritage. Modeling and creation of unified, structured and extensible artwork badge, here referred as booklet, represents the base to exploit such structured information as the building block for innovative amazing and more involving multimedia fruition paths in the cultural heritage domains....
Japan is one of the countries where life expectancy of nation is the highest in the world. In addition to maintaining social health care system and social health insurance system, health care activity by an individual is recognized as more important. On of the obstacles which prevents the individual user from utilizing personal health record(PHR hereafter), such as health diagnosis data, is due to...
This paper presents a vertical interactive surface that can put out both analog and digital information and that can be used as a digital signage and community board in public spaces. Our proposed system uses a magnetic object to not only attach the analog information but also control the digital information. In this system, by attaching the object to the system surface directly, digital information...
Based on poly-phase sampling and lookup table encryption techniques, a new image sharing scheme is presented with several aspects of innovations in this paper. Each shadow can be independently decrypted to obtain part of the original image, any pair of decrypted sub-images has very high correlation, it still obtains acceptable image quality when channel congestion occurs, and quality refinement of...
We have proposed a mixed reality based painting system. In this paper, we tackle a problem in our previous painting system that fully relies on magnetic sensor that is attached on the canvas, the users needed to detach and attach a sensor on the canvas during painting when they want to switch the canvas. Instead of that, in this paper, we aim to automatically detect the shape of the canvas for registration...
Summary form only given, as follows. The tutorial will present a holistic design and verification framework to investigation of image/video processing in embedded environments, with emphasis on system-on-chip architectures. Starting with an executable specification of a target application, subsequent transformations are performed across different levels of abstraction until the final implementation...
