Real-time Omni-directional Distance Measurement with Active Panoramic Vision
Sooyeong Yi,Byoungwook Choi,Narendra Ahuja 대한전기학회 2007 International Journal of Control, Automation, and Vol.5 No.2
Autonomous navigation of mobile robot requires a ranging system for measurement of distance to environmental objects. It is obvious that the wider and the faster distance measurement gives a mobile robot more freedom in trajectory planning and control. The active omni-directional ranging system proposed in this paper is capable of obtaining the distance for all 3600 directions in real-time because of the omni-directional min-or and the structured light. Distance computation including the sensitivity analysis and the experiments on the omni-directional ranging are presented to verify the effectiveness of the proposed system.
Clinical behaviour and outcome in pediatric glioblastoma: current scenario
Aditya Kumar Singla,Renu Madan,Kirti Gupta,Shikha Goyal,Narendra Kumar,Sushant Kumar Sahoo,Deepak K. Uppal,Chirag K. Ahuja 대한방사선종양학회 2021 Radiation Oncology Journal Vol.39 No.1
Pediatric glioblastoma (pGBM) is a rare entity accounting for only approximately 3% of all childhood brain tumors. Treatment guidelines for pGBM have been extrapolated from those in adult glioblastoma. Rarity of pGBM and underrepresentation of pediatric population in major studies precludes from defining the ideal treatment protocol for these patients. Maximum safe resection is performed in most of the cases followed by postoperative radiotherapy in children over 3 years of age. Benefit of temozolomide is unclear in these patients. Here, we present the clinicopathological details and outcome of six pGBM patients treated at our institute in 2018–2019.
