A Bit-Level Concurrent Visual Programming Language (A-BITS) and a Base Computation Model (APC) for Its Development

Few visual programming languages based on models of bit-level concurrent computation have been developed. Our programming language is useful for developing asynchronous and concurrent programs, which frequently use bit-level operations. Recently, use of such programs has been increasing in fields like video game design, multimedia, and graphical user interfaces. We also

We associate with each edge ei E E an ordered pair of rational numbers (ai, bi). Let the weight of a spanning tree T, w(T), be defined as xeiET ai + netET bi. A spanning tree T in G is called a w-optimum spanning tree if w(T) > w(T') for all spanning trees T' in G. The function w is one instance in a class of two-parameter objectives. Hassin and Tank proposed a unified approach for solving the class of two-parameter objective optimum spanning tree problems. Let s be an objective in the class and Fs(G) denote the weight of the s-optimum spanning tree of G. The element perturbation problem of the s-optimum spanning tree is to compute FS (G-ek) for all ek E E. With Hassin and Tank's approach, let ts(p, q) be the complexity of computing the s-optimum spanning tree where p = [VI and q = IEl. In this paper, we present an approach to solve the element perturbation problem of the s-optimum spanning tree in t,(p, q).

As a background to these things, various analysis methods have been developed to clarify and visualize the subject's mental state based on these data. We tried to reveal and visualize the transition patterns of the subjects' mental states by analyzing their utterances. Furthermore, we developed an interactive system of visualization of psychological state to support visual understanding of psychological topology. Features have been implemented to enable multidimensional data to visualize the movements shown on the SOM map. In this paper, we describe the system that can interactively visualize psychological states.

Ambiguous information can be handled quantitatively by using fuzzy theory, and representing it in an easy-to-understand manner is critical. One solution is to visualize an ambiguous relationship by using fuzzy graph representation, which has the essential characteristic of expressing variable relationships in between its nodes. We previously proposed an algorithm to draw intelligible and comprehensive fuzzy graphs. This study describes an improved drawing method for that graph drawing algorithm. As a result, highly related nodes were arranged closer to one another, and the display area was reduced. This method can be used as an effective means of expressing the results of ambiguous information analysis.

A great deal of data about users has been generated through these years. The counselor needs to grasp the user’s situation from these data. However, since there are various types of data, it is very difficult to compare among different kinds of data and extract features from them. To cope with these problems, it is useful and helpful to visualize data. Visualization of data is an important theme in various fields. There are many studies and tools concerned with visualizing data. Among them, Excel is a typical software used by many people to visualize data in 2D graphs. However it is recognized that 2D graphs have various restrictions. On the other hand, now we are attempting to incorporate SCT (Sentence Completion Test) into the web counseling system. SCT is used as one type of psychological assessment by hospitals, schools, companies, and so on. Its effect...

However, the development burden of embedded systems tends to be high because they are complex. A visual development environment is one way to reduce this burden. We have already proposed a visual programming development environment for program diagrams called Hichart. In this paper, we describe a visual development environment for the XC language, which is a programming language for XMOS evaluation boards.
Effectiveness of Multi-touch Interface for Fuzzy Graph Analysis

There is a sociometry analysis that applies the fuzzy graph an approach to clearly express the measurement and evaluation of the structure of human relationships. The analysis conditions are not constant in the analysis of human relationships, and not in addition to performing the analysis by trial and error for that. Previously in the study, in the relationship such as between the groups, it has not been studied the individual relationships analysis in the groups. Similarly, it has never been also studied to analyze the human relationships dynamically. We propose a method to dynamically the human relationships by intuitive operation through the touch interface. In this paper, we describe our principle of the sociometry analysis that using the fuzzy graph, the our method through the touch interface, and their application to sociometry analysis in case of 30 people of human relationships.

Generally the data is saved and is organized on the database system with some kinds of keywords and its clustering. In the case of performing the decision for some problems, we often refer to past cases that are similar to the problem. In such a case, if solutions of past cases are kept in the database as documents, it is very useful to solve a problem. We propose a new information retrieval system based on-heuristic key words extracted from documents and a set of clusters for the documents.
Fuzzy Database and Interface to Analyze Management System Operations

Efficient engagement with business operations is an issue; consequently, understanding and analyzing actual situations is required. We have been researching analysis methods using fuzzy theory, which enables imprecise expressions. By building a useful fuzzy database and realizing an analysis method for management system operations, our goal is to develop a useful tool for organizational management. In this paper, we introduce the concept of fuzzy database construction, an analysis method, and a case study related to management system operations.
