In order to solve the problem of point clouds coordinate conversion of non-directional scanners, this paper proposes a basic Rodrigues rotation method. Specifically, we convert the 6 degree-of-freedom (6-DOF) rotation and translation matrix into the uniaxial rotation matrix, and establish the equation of objective vector conversion based on the basic Rodrigues rotation scheme. We demonstrate the applicability of the new method by using a bar-shaped emboss point clouds as experimental input, the three-axis error and three-term error as validate indicators. The results suggest that the new method does not need linearization and is suitable for optional rotation angle. Meanwhile, the new method achieves the seamless splicing of point clouds. Furthermore, the coordinate conversion scheme proposed in this paper performs superiority by comparing with the iterative closest point (ICP) conversion method. Therefore, the basic Rodrigues rotation method is not only regarded as a suitable tool to achieve the conversion of point clouds, but also provides certain reference and guidance for similar projects.

This study is strategically researched to regain the signification of capstone design by correcting the errors neglected the importances of meetings in the convergent English translation capstone design. For this, intial-meetings were designed to be students-centered except for explaining some basic knowledge and information. Mid-meetings were completely students-centered for the students to present their ideas, debate the contents and give feedbacks to one another. Final-meetings were also students-centered for the students to adjust and confirm the results. To validate the importance of students-centered meetings, the qualitative study has been done through interviewing students. In the interviews, almost all of them said they had motivation, confidence, and self-efficacy. Finally attempting capstone design in the future, students-centered meetings should be considered important. Hopefully this kind of capstone design will be used and studied continuedly and lively as a useful method in the field of English education.

The clusters of orthologous groups of proteins (COG) algorithm was applied to identify essential proteins in eukaryotes and to measure the degree of conservation. Sixty-three orthologous groups, which were conserved in 66 microbial genomes, enlarged to 104 eukaryotic orthologous groups (KOGs) and 71 KOGs were conserved at the nuclear genome of 7 eucaryotes. Fifty-four of 71 translation-related genes were conserved, highlighting the importance of proteins in modern organisms. Translation initiation factors (KOG0343, KOG3271) and prolyl-tRNA synthetase (KOG4163) showed high conservation based on the distance value analysis. The genes of Caenorhabditis elegans appear to harbor high genetic variation because the genome showed the highest variation at 71 conserved proteins among 7 genomes. The 71 conserved genes will be valuable in basic and applied research, for example, targeting for antibiotic development.

This paper proposes a basic implementation of bi-directional transition system between Korean and Japanese. The syntactic structure of Korean language is very similar to that of Japanese. In order to use the same main program for bi-directional translation, system is classified into two parts. One is directly translatable part and the other is untranslatable part by direct matching because of different structure. Solving these problems, the syntactic and semantic informations control bi-directional interpreting process and make equivalent syntactic level between two languages.

Light is an environmental signal that regulates photomovement and main energy source of photosynthesis in the cyanobacterium Synechocystis sp. PCC 6803 (Syn6803). Syn6803 is a popular model system for study of plant functional genomics. In this report, we adopted 2D gel based proteomics study to investigate proteins related with the light absorption and photo-protection in Syn6803. More than 700 proteins were detected on the SDS-gels stained with silver nitrate. Several proteins showing different expression level under various light conditions were identified with MALDI-TOF Mass spectrometry. As a comparison, we also conducted ICAT-based proteome study using WT and cphl (cyanobacterial phytochrome 1) mutant. A cphl deletion led to changes in the expression of proteins involved in translation, photosynthesis including photosystem and CO2 fixation, and cellular regulation. We are currently involved in TAP-tagging method to study protein-protein interactions in search for the molecular component involved in the light signal transduction of Syn6803 photomovement.

After automatic translation system for hangul's romanization based on the World Wide Web converting korean-word, sentence, document to Transliteration letters by applying algorithm based phonological principles. even though a user do not know the basic principles of the usage of Korean-to-Romanization notations, It refers to corresponding character table that has been currently adopted the authority's standard proposition for Korean-to-Romanization notation rule concurrently, add to make possible to convert a machinized code as well. It provides font for toggling Korean-English mode, insert-edit mode by assigning ASCII codes and Unicode are hardly used to them. This program could be made in C++ progamming language and Unified Modeling Language to implement various font. font-expanding and condensing. alternative printing.

This paper introduces Web Accessibility to web pages, which is the basic method of obtaining information in modern Internet. Also we explore the system that is capable of examine whether the corresponding web pages are following the accessibility regulation. In order to examine web pages, we need to classify all the objects that web page contains. And the classified objects are to be examined by the standards of Web Accessibility. And also this paper introduces the mobile translation system for web accessibility.

This study propose a new approach to control the optimal working path of vertical type articulated robot with translation joint for trimming working process automation in forging manufacturing process. The basic structure of the proposed robotic joints controller consists of a Proportional-Intergral controller and a Proportional-Derivative controller in parallel. The proposed control scheme takes advantage of the properties of the fuzzy PID controllers. The proposed method is suitable to control of the trajectory and path control in cartesian space for vertical type articulated robot manipulator. The results illustrates that the proposed fuzzy computed torque controller is more stable and robust than the conventional computed torque controller. The reliability is varified by simulation test for vertical type s articulated robot with seven joints including one trqanslation joint.

In this paper, we design and implement CTOC, a new bytecode analysis and translation tool. We also propose E-Tree, a new intermediate code, to efficiently deal with intermediate codes translated from bytecodes. E-Tree is expressed in a tree form by combining relevant bytecode instructions in basic blocks of eCFG to overcome the weaknesses of bytecodes such as complexity and analytical difficulty. To demonstrate the usefulness and possible extensibility of CTOC, we show the creation process of eCFG and E-Tree through practical bytecode analysis and translation and shows the optimization process of a bytecode program as an example of possible extensibility.
