1. Proposal of a Supporting Method to Generate a Decision Table from the Formal Specification

Tetsuro Katayama, Kenta Nishikawa, Yoshihiro Kita, Hisaaki Yamaba, Naonobu Okazaki
Pages: 174 - 178
In recent years, the software quality becomes more important because the system becomes large scale and high performance. In general, many defects are embedded in the upstream process of the software development. As one reason of the above, specifications include ambiguous description. As a means for...

2. A Comparative Study of Inter-firm Transactional Relationship between Kyohokai and Yokokai

Takao Ito, Makoto Sakamoto, Satoshi Ikeda, Rajiv Mehta, Yasuo Uchida
Pages: 179 - 183
Although two major Japanese manufacturers, Toyota and Mazda, compete in the automotive market, their corporate performance, respectively, is different because the internal resources and the way they coordinate interrelationships among their network partners is known to be divergent. Both these two companies...

3. Comparing Effectiveness of Feature Detectors in Obstacles Detection from a Video

Shaohua Qian, Joo Kooi Tan, Hyoungseop Kim, Seiji Ishikawa, Takashi Morie, Takashi Shinomiya
Pages: 184 - 188
We have already proposed an obstacles detection method using a video taken by a vehicle-mounted monocular camera. In this method, correct obstacles detection depends on whether we can accurately detect and match feature points. In order to improve the accuracy of obstacles detection, in this paper, we...

4. Some Accepting Powers of Bottom-Up Pyramid Cellular Acceptors with n-dimensional Layers

Makoto Sakamoto, Makoto Nagatomo, Tatsuma Kurogi, Satoshi Ikeda, Masahiro Yokomichi, Hiroshi Furutani, Takao Ito, Yasuo Uchida, Tsunehiro Yoshinaga
Pages: 189 - 193
In theoretical computer science, the Turing machine was introduced as a simple mathematical model of computers in 1936, and has played a number of important roles in understanding and exploiting basic concepts and mechanisms in computing and information processing. After that, the development of the...

5. Human Recognition based on Gait Features and Genetic Programming

Dipak Gaire Sharma, Rahadian Yusuf, Ivan Tanev, Katsunori Shimohara
Pages: 194 - 197
Human walking has always been the curious field of research for different disciple of social and information science. The study of human walk or human gait in association with different behaviors and emotions has not only fascinated social science researchers, but its uniqueness has also attracted many...

6. Circulative Narrative Generation Based on the Mutual Transformation between Narrative Conceptual Structures and Music in the Integrated Narrative Generation System

Taisuke Akimoto, Takashi Ogata
Pages: 198 - 202
We have proposed a new framework of narrative generation which generates narratives through the mutual transformation according to various pathways between narrative (conceptual representation) and music. This paper will continuously incorporate this framework into the integrated narrative generation...

7. Homogeneous Systolic Pyramid Automata with n-Dimensional Layers

Makoto Sakamoto, Makoto Nagatomo, Tatsuma Kurogi, Satoshi Ikeda, Masahiro Yokomichi, Hiroshi Furutani, Takao Ito, Yasuo Uchida, Tsunehiro Yoshinaga
Pages: 203 - 206
Cellular automata were investigated not only in the viewpoint of formal language theory, but also in the viewpoint of pattern recognition. Cellular automata can be classified into some types. A systolic pyramid automata is also one parallel model of various cellular automata. A homogeneous systolic pyramid...

8. Proposal of a Supporting Method for Debugging to Reproduce Java Multi-threaded Programs by Petri-net

Tetsuro Katayama, Shoichiro Kitano, Yoshihiro Kita, Hisaaki Yamaba, Naonobu Okazaki
Pages: 207 - 211
It is difficult to implement the multi-threaded programs. The reason is that the behavior of each thread is non-deterministic. Also it is difficult to reproduce the situation in which an incident occurs. This paper proposes a supporting method for debugging to reproduce Java multi-threaded programs by...

9. Remarks on Recognizability of Four-Dimensional Topological Components

Makoto Nagatomo, Makoto Sakamoto, Tatsuma Kurogi, Satoshi Ikeda, Masahiro Yokomichi, Hiroshi Furutani, Takao Ito, Yasuo Uchida, Tsunehiro Yoshinaga
Pages: 212 - 215
The study of four-dimensional automata as the computational model of four-dimensional pattern processing has been meaningful. However, it is conjectured that the three-dimensional pattern processing has its our difficulties not arising in two- or three-dimensional case. One of these difficulties occurs...

10. Robot Pose Measurement Based on Sensor Fusion

Jiwu Wang, Shunkai Zheng, Fangbo Liao, Masanori Sugisaka
Pages: 216 - 219
In the motion control research of mobile robot, the mobile robot pose is obtained by derivation of the Kinematic model of the robot. Generally, the motion model relies simply on the data from encoder feedback. Due to cumulative error, the robot pose accuracy is relatively poor by mileage positioning...

11. Markov Chain Analyses of Random Local Search and Evolutionary Algorithm

Hiroshi Furutani, Hiroki Tagami, Makoto Sakamoto, Yifei Du
Pages: 220 - 224
Theoretical studies of evolutionary algorithms (EAs) have been developed by researchers whose main interests are convergence properties of algorithms. In this paper, we report the computational complexity of an algorithm that is a variant of (1+1) EA, called Random Local Search (RLS). While a standard...

12. Runtime Analysis of OneMax Problem in Genetic Algorithm

Yifei Du, QinLian Ma, Makoto Sakamoto, Hiroshi Furutani, Yu-an Zhang
Pages: 225 - 230
Genetic algorithms (GAs) are stochastic optimization techniques, and we have studied the effects of stochastic fluctuation in the process of GA evolution. A mathematical study was carried out for GA on OneMax function within the framework of Markov chain model. We obtained the steady state solution,...

13. An Action Selection Method Using Degree of Cooperation in a Multi-agent Reinforcement Learning System

Masanori Kawamura, Kunikazu Kobayashi
Pages: 231 - 236
In recent years, a concept of a dividual is proposed by a Japanese novelist to interact properly with another person. To construct a model of the dividual, the degree of cooperation is assigned to the corresponding dividual. By introducing the degree of cooperation into a multi-agent system, we evaluate...
