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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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...

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,...

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...

In this paper, using the notion of a binary Channel Matrix as well known in Information Theory, we present an equivalent relation between the SPRT (Sequential Probability Ratio Test) and Bayes’ Updating. Moreover, we show the relationship between the SPRT and NSPR (New Sequential Probability Ratio) where...

This paper proposes a novel transistor-like device by the optical coupling of LED (Light Emitting Diode) and Photodiode. The device that we call “OCT: Optical Coupling Transistor” shows an amplification function if the Photodiode current by photo electromotive force is feed backed into the LED, in the...
