  • This thesis is about to find possible opportunity to use Freeware Software in development and application of Digital Contents Creation software. There are 2D composition and Editing software, 3D production software and rendering Software as major part and motion capture, 3D Digitizing and other software operate in and out facilities in small part in Digital Contents Creation Software area. Most of Digital Contents Creation Software made by foreign countries such as USA and Canadian film, game and animation Digital Contents Creation industry, this causes higher production cost and lower profit of studios and usage of illegal copy of Digital Contents Creation Software as well. This thesis tried to present a solution to use Freeware Software in production process by researching and analyzing international and domestic software market and global trend of Freeware Software and present Freeware Software software in each production steps. This thesis include performance test of commercial render Freeware software.

  • The development of a simulation system requires many sub modules such as a dynamic module, a visualization module, etc. If a different freeware is used for each sub modules, it is hard to develop the simulation system by incorporating them because they use their own data structures. To solve this problem, a high-level data structure, called Dynamics Scene Graph Data structure (DSGD) is proposed, by wrapping data structures of two freeware; an Open Dynamics Engine (ODE) for the dynamic module and an Open Scene Graph (OSG) for the visualization module. Finally, to evaluate the applicability of the proposed data structure, it is applied to the block erection simulation in shipbuilding. The result shows that it can be used for developing the simulation system.

  • This paper aims to introduce some useful multimedia freewares, and also support Chinese instructor with discussing how to operate them for instructional design of multimedia language learning class. For this aims, this paper consists of three parts: First, instructional design. This part is focused to what kind of instructional model to be based on, for example, Dick & Carey model, ADDIE model, ASSURE model etc. This part introduces these models, and modifies ADDIE and ASSURE model to D.D.A.I.E.S and S.S.A.U.R.E.S as 'A(nalysis)' in these model may apply to the next 'D(evelopment)' on ADDIE, 'S(elect Methods, Media and Materials)' on ASSURE in the practical Chinese class. Second, Programme: What to use. This part is focused to what kind of free software we can use. In the web site online, there are huge free softwares so we usually hesitate to select and also don't know how to operate even though selected one of them. This part, accordingly, introduces ten of useful freewares and compares each other in terms of usefulness for Chinese instructors. Third, Programme: How to use. It is of no use just to know what to use but not to know how to operate, so this part describes how to use freewares like a kind of manual in detail as far as possible. In conclusion, we hope more Chinese instructors to learn and use more useful freewares for designing the better multimedia Chinese class by this paper.

  • The compiler is the key of the prototyping framework for the new memory system. These compiler-centric prototyping tools have several components, including compiler, linker, assembler, and standard libraries. It takes a lot of cost and man power to develop it all at zero base. Therefore, developer usually use a development framework to develop these prototyping tools efficiently. These development frameworks should be free of licensing issues when considering the commercialization of development results. Thus, developer should investigate the development framework, which is free from licensing issues and that provides all of the development environment to enable actual execution. There are three representative compiler-centric development frameworks: GCC, Clang (LLVM), and MS visual studio. There are some differences depending on the release version among them. And, there are some limitations to the freeware and commercial use. We chose LLVM here to explain the development of prototyping tools. This information will help accelerate the development of prototyping tools and will help reduce system development costs.

  • In this paper, visualization of Visible Human data offered by NLM(National Library of Medicine) is performed using $VTK^{TM}$. Computed Tomography Data set(axial, $587\times341\times256$, and the distance between slices 1mm) is used throughout the study. Before the actual visualization routine, 8 bit-reader class of VTK is developed to transform CT data to VTK dataset. After that, the visualization procedures are done to display 3D image on PC. VTK is freeware, not a commercial software. The results of VTK show relatively good image quality and slower processing time compared with the commercial softwares like IAP, IDL, AVS. Thus if processing time is not the critical factor, VTK is worthy to be used in visualization of the medical images.

  • This study was carried out to improve the performance of a vertical-axis micro wind turbine. It is unique in that it has two identical generators on both sides of the main shaft. Also it has a C shape frame to fix the generators and the main shaft firmly and to provide a connection to a tower. Performance analysis of the wind turbine rotor was performed using Qblade, which is an analysis program for vertical axis wind turbines and freeware. Based on the analysis results, the blade airfoil, the chord length, and the rotor size were modified to improve the performance of the rotor. The modification was found to increase the performance of the wind turbine and to reach the targeted rated power.

  • The objects of the nature have three dimensional (3-D) parameters. The 3-D profiles are embedded on the photographs and microscopic images. To understand 3-D configuration, stereo pair image with thick section is frequently employed. The perception of 3-D images is possible with the aid of stereoscopic glasses, although the expert can perceive 3-D images without the glasses. Anaglyphic stereo images are constructed by various softwares from commercial and freeware. Here we would like to present an easy anaglyphs construction method with Adobe $Photoshop^{(R)}$ based on tilting paired images from high voltage electron microscope. The anaglyphic stereo images constructed revealed the same 3-D perception with conventional stereoscopy. We could zoom in/out the anaglyph image digitally to investigate the detail configuration by real time. This method is expected to contribute to understanding complex structures 3 dimensionally.

  • In this paper, we write about EDISON program. We study about where to use this program. We can use this program for FEA naturally. But we study that using this program in class. Many students can't understand many mechanics of materials' problem. They want to see image such as change of beam. It can help students to understand many problem. We can use ANSYS or Abaqus. But EDISON program is better for students because of it is freeware. In this paper, I write two problem. One is peak stress of basic beam, another is shearing stress flow of I-beam. On the basis of this, EDISON program will be widely used.
