Research ArticleOpen accessIn the author namesFixed-Star Tracking Attitude Control of Spacecraft Using Single-Gimbal Control Moment GyrosSangwon Kwon, Yuki Tani, Hiroshi Okubo, Takashi ShimomuraProblem statement: A cluster of small-sized Single-Gimbal Control Moment Gyros (SGCMGs) is proposed as an attitude control actuator for high-speed maneuver of small satellites. There exists a singularity problem what is peculiar to the CMG system. Approach: This study presented a simple singularity avoidance steering law using the Singular Value Decomposition (SVD) algorithm. Results: Capability of the present steering method … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 7,981 accessesView PDF Cite

Research ArticleOpen accessIn the author namesQuery Pattern-based Relational Data to XML Data Translation AlgorithmJinhyung Kim, Dongwon Jeong, Doo-Kwon BaikThis paper proposes a new query pattern-based relational schema-to-XML schema translation (QP-T) algorithm to resolve implicit referential integrity issue. Various translation methods have been introduced on structural aspects and/or semantic aspects. However, most of conventional methods consider only explicit referential integrities specified by relational schema. It causes several problems such as incorrect transformation, abnormal relational model transition and so on. … …Journal of Computer Science, Vol. 3, Issue 4 · 30 Apr 2007 · 7,192 accessesView PDF Cite
