Multi-sectoral Cluster Modelling: The Evaluation of Scottish Enterprise Cluster Policy

This article describes the ex post cluster evaluation framework being developed by Scottish Enterprise. It focuses primarily on the macro level evaluation and, in particular, on the use of multi-sectoral modelling techniques to identify the effects of cluster policy on key indicators such as gross domestic product (GDP), unemployment and competitiveness. The Scottish Input-Output (I-O) table is a key element in this approach. The strengths and weaknesses of I-O data, both as a basis for this analysis and as a means of identifying important intra-cluster linkages are explored. Further, the article describes methods for visual representation of the linkages identified using such a method.

Written orthopedic patient education materials from the point of view of empowerment by education

Written patient education materials are one way of supporting patient empowerment. The aim of this study was to evaluate written orthopedic patient education materials ( n=25) drawn from a university hospital’s electronic databank. In the absence of suitable tools for evaluation, an analytic framework was developed by a panel of nursing scientists and clinical experts. The materials were evaluated from the point of view of empowerment by their external appearance, content and instructiveness. In terms of their external appearance the materials were well prepared, but much was left to be desired with regard to contents and instructiveness. Development needs to focus on making better use of methods of visual representation, on increasing the coverage of content areas that so far have received less attention, like social, experiential, ethical and financial empowerment, and on providing a more focused perspective on the patient.

Stereo Image Processing and Virtual Reality in an Intelligent Robot Control System

This paper can be divided into two main parts. Both of them describe one of those parts of an intelligent robot control system, which makes the system capable to interact with its environment via visual information. The two parts can be handled as complementary parts of each other. The first part shows the solution of the data extraction from the visual information. This is a well known machine vision problem, in this case, the applied method is a passive stereo type. The second part explains the method of visual representation of the data. This is a visualization problem, in this case, a virtual reality system is used. With the use of the detailed graphic models of VR, efficient off-line robot programming and simulation is available.

Filmic space-time diagrams for video structure representation

In this paper, we propose a novel approach to computer representation for interactive film editing. We describe a prototype system developed at Lancaster which uses this approach, and show how such a system supports film editing. Our work involves the isolation of several principles of filmicity and the combination of these with an event structure and film grammar to produce a system which can intelligently edit a film. Filmic principles are rules which can be used when editing a film to produce a sequence which guarantees a smooth perception of the film in its entirety. The visual structure representation method discussed herein is a tool used in our research.

Package Flow Model and Its Fuzzy Implementation for Simulating Nuclear Reactor System Dynamics

A simple intuitive simulation model, which we call “Package Flow Model”, has been developed to evaluate physical processes in nuclear reactor system from a macroscopic point of view. In the previous paper, we showed the physical process of each energy generation and transfer stage in a PWR could be modeled by PFM, and its dynamics could be approximately simulated by fuzzy implementation. In this paper, a PFMs network approach for a total PWR system simulation is proposed and some transients of nuclear ship “MUTSU” reactor system are evaluated. The simulated results are consistent with those from Nuclear Ship Engineering Simulation System developed by JAERI. Furthermore, a visual representation method is proposed to intuitively capture the profile of fuel safety transient. Using the PFMs network, we can handily calculate the transient phenomena of the system even by a notebook-type personal computer. In addition, we can easily interpret the results of calculation surveying a small number of parameters.

空間相関関数とその統計的検定の実用的計算手法と視覚化 : 実用的メッシュデータ解析システム構築のための空間相関分析法の体系化 その1

The space correlation analysis (SCA) was proposed with its possibility of application on urban analysis in our previous papers. The calculating program of SCA, however, is not easy to develop for urban planners because the program has a relatively large size and complicated. The calculating theory is reconstructed to make SCA fit for practical use. The following possibilities of calculating method of SCA are shown ; 1) the space influence function (SIF) can be calculated by using ordinary library program, 2) the space correlation function (SCF) can be calculated very rapidly by using FFT (fast Fourier transform). Also presented in this paper are visual representation methods of SCA model with reliable range of estimated parameters. It is very important in actual planning to know the structure of spatial influence relation of urban activities accurately and intuitionally. Using the statistical range estimation and testing theory, 1) the method for getting the confidence interval of SCF is shown, and 2) the method for grouping the value of SCF is shown. The visual presentation of the results of the above methods are very effective to assist urban planners to understand the characteristics of spatial relation of urban activities.
