cBDI-based Collaborative Control for a Robotic Wheelchair

In this paper we present a collaborative control architecture for a robotic wheelchair with the aim of providing "assistance as required". The architecture is based on cBDI - an extension to the Belief-Desire-Intention model to support human-machine collaboration. We present results of an evaluation of the architecture in a simulated environment and conclude that collaborative control could ensure "feeling in control" even under assistance

Case report of a rare case of Non-hodgkin Lymphoma presenting as sternal mass

Primary or metastatic tumors of the chest wall constitute 5% of all thoracic tumors and lymphoma comprises about 2% of all chest wall tumors. We report a case of a 23year old male presenting with anterior chest wall mass for the past 6 months which was slowly growing in size. There was no other symptoms of respiratory difficulty, cough, and hemoptysis. HRCT chest revealed soft tissue attenuated lesion in mid chest wall and infiltration to the anterior mediastinum with erosion of sternum and the 8th rib. FNAC of the site revealed Non-Hodgkin Lymphoma. Diagnosis is based on morphological features, FNAC, cell block
