A new design for actively steered bogies (Simson S., 2007) has been proposed for tractive rollingstock to improve not only wheel rail wear and rolling contact fatigue but to also improve wheel rail adhesion. The new bogie design features forced steering with active yaw control of the secondary suspension. The control alternatives for the new bogie design are limited by the need for the control ...
Satellite ground track display computer program is designed and implemented for the KOMPSAT-2 mission operations. Digitized world map and detailed Korean map is realized with zoom and pan capability. The program supports real-time ground trace and off-line satellite image planning on the world map. Satellite mission timeline is also displayed with the satellite ground track for the visualized m...
The TREC Session track ran for the fourth time in 2013. The track has the primary goal of providing test collections and evaluation measures for studying information retrieval over user sessions rather than one-time queries. These test collections are meant to be portable, reusable, statistically powerful, and open to anyone that wishes to work on the problem of retrieval over sessions. The exp...
Stress Analysis of Switchover Module with Al6061-T6 and Al7075-T6 for Hybrid Locomotion Mobile Robot
This study presents the design and stress analysis of mobile robot switchover module (track tensioner), which helps the robot to work in hybrid locomotion mechanism. The track tensioner is a loading and unloading module that helps the locomotion system transformability while robot moves either on wheel or track mechanism. The selection of suitable material for its design, the model is therefore...
investigations on vibration behaviors of railway track systems were attempted in this research. this was made by conducting a comprehensive field investigation into the free vibration of track systems and response of tracks to train moving loads. in-situ modal analysis was used in a railway track field as an efficient method of investigating dynamic properties of railway track systems. natural ...
BACKGROUND Recent developments in large bowel surgery are the introduction of laparoscopic surgery and the implementation of multimodal fast track recovery programs. Both focus on a faster recovery and shorter hospital stay. The randomized controlled multicenter LAFA-trial (LAparoscopy and/or FAst track multimodal management versus standard care) was conceived to determine whether laparoscopic ...
Design projects are cooperative activities in which several actors from several fields work together in order to rich a goal. The challenge is how to keep track of knowledge from daily work in this type of activity. Projects documents are not sufficient to be analysed to extract this type of knowledge. This paper presents techniques to acquire and represent knowledge from design projects. A spe...
