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)
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)
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 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)
This paper proposes a method to automatically organize and visualize related work events as a work-project structure. This is accomplished by accumulating and analyzing the target event and time of the user's operations such as registrations and references on a Personal Information Management system (PIM). Our processes for organization are : (1) extracting… (More)
