Publication Embargo Design and Analysis of An Anthropomorphic Two-DoF Ankle-Foot Orthosis(IEEE, 2019-04-19) Ranaweera, R. K. P. S; Abayasiri, R. A. M; Gopura, R. A. R. C; Jayawardena, T. S. S; Mann, G. K. IThis paper proposes a two-degrees of freedom passive-dynamic ankle-foot orthosis (AFO). In view of enhancing anatomical conformity, an anthropomorphic design is proposed to minimize mechanical interferences between ankle and orthosis. The biomimetic features such as passive stabilizers and dampeners in the proposed mechanism intrinsically support the ankle and foot to maintain stability and improve shock-absorbing ability. The mobility, ranges of motion, and manipulability measures for the proposed AFO have been investigated using mathematical modeling and simulation approaches. The analysis revealed the effectiveness of the proposed AFO in meeting the complex kinematics of ankle joint compared to the predecessors. Potentially, the proposed AFO can serve as a platform to carry out research and development on robotic orthoses for the lower extremity.Publication Embargo Design and Analysis of An Anthropomorphic Two-DoF Ankle-Foot Orthosis(IEEE, 2019-04-19) Ranaweera, R.

A. R. C; Jayawardene, T. S. SThe material prices of poly bags skyrocket to new heights and forecasters see no end to this trend. Also legal restrictions are imposed on some types of polythene products. In this situation, any entrepreneur engaging in the poly bag manufacturing process faces significant challenges. Therefore, a case study of an analysis of risks and bottlenecks of a poly bag manufacturing factory was carried out for the purpose of modeling and simulation of a poly bag manufacturing factory to improve the productivity to face the underlying challenges. This paper presents the analysis methods, and the results of the analysis are also discussed.
