Pages: 221 - 225
Pattern reformation problem on a grid plane is an interesting problem. Suppose there is a group of mobile robots on a square grid plane with the number of robots equaling to the number of columns/rows of the grid plane. The mobile robots are commanded to change to another formation as soon as possible....

5. Adaptive Consensus via Dynamic Feedback Control for Lipschitz Nonlinear Multi-Agent Systems

Lin Li, Heyang Wang
Pages: 226 - 229
This paper deals with the consensus problem for multi-agent systems with fixed topologies. The agents are described by Lipschitz nonlinear systems. Only output information of each agent can be obtained from its neighbor agents. A distributed adaptive consensus algorithm via dynamic output feedback is...

6. Feature Linking using Synchronized Responses in Chaotic Cellar Neural Networks for Visual Stimulus of Moving Objects

Akihiro Yamaguchi, Satoshi Arakane, Masao Kubo
Pages: 230 - 233
A feature-linking mechanism using the synchronized responses of neural assemblies was studied for chaotic cellar neural networks (Chaotic-CNN). Chaotic-CNNs consist of chaotic spike response neurons that show chaotic inter-spike-interval dynamics. In our scheme of feature linking, the features of the...

7. Fast collective photographic subject detection without pixels by an assumption about a shoot and its elevation angle

Sora Tanioka, Masao Kubo, Hiroshi Sato
Pages: 234 - 237
In this paper a method that discovers socially attracted photographic subjects in real time is proposed. This needs only non-pixel information of a digital photograph for this discovery which include a time of shoot, GPS location where a photograph is taken, a bearing of the shoot and so on. Thinformation...

8. An FPGA-based cortical and thalamic silicon neuronal network

Takuya Nanami, Takashi Kohno
Pages: 238 - 242
A DSSN model is a neuron model which is designed to be implemented efficiently by digital arithmetic circuit. In our previous study, we expanded this model to support the neuronal activities of several cortical and thalamic neurons; Regular spiking, fast spiking, intrinsically bursting and low-threshold...

9. A Design Plan of a Game System including an Automatic Narrative Generation Mechanism: The Entire Structure and the World Settings

Jumpei Ono, Takashi Ogata
Pages: 243 - 246
In this paper, we propose a narrative generation system based on the scenario generation method in tabletop role-playing games (TRPGs). This system uses an integrated narrative generation system (INGS) that synthesizes various narrative generation mechanisms. The TRPG is an analog game in which one or...
