Is ~S~CT Thk paper proposes a presentation agent designed for a virtual environment The agent, animated in the virtual environment, performs a presentation based on a speech teti that e~~lns objects in the environment. h order to gene~te the agent's motion automatim~, we categotie the presentation motions of the agent into three classes, pointing, moving,… (More)
We are investigating the logistic map over integers and its pseudorandom number generator. Focusing on differences between the logistic maps over floating-point numbers and over integers, we herein show that the integer format is a suitable representation for implementing the logistic map on computers with limited memories.
In the present paper, we show a design guide of a pseudorandom number generator using the logistic map with finite precision. First, we define three basic operations and two basic models of the pseudorandom number generator using an iterative map. Second, we implement two pseudorandom number generators employing their models with the logistic map with… (More)
In businesses, knowledge of work is represented by a sequence of related work events and management of these relations is very important for users. This paper proposes a method that automatically groups related work events from user's operation record on a Personal Information Management system(PIM). We assume that the related work events on a PIM are… (More)
In recent years, route bus service systems have been collecting and accumulating bus probe data such as GPS positions and traffic speeds from all route buses, day after day. In the present paper, we propose a method to analyze the conditions of a road traffic network from a huge amount of the route bus probe data. First, we show a conversion method from the… (More)
