Let X be a nonsingular, projective curve of genus g ≥ 2. Then the elements of order r of the Jacobian of X act in a natural way on the moduli space M(r, ξ) of stable vector bundles on X of rank r( ≥ 2) whose determinants are isomorphic to a given line bundle ξ of degree d. We shall assume that r and d are coprime and show that the fixed point variety corresponding to any element μ (strictly) of order r is an abelian variety. In fact, this fixed point variety is isomorphic to the generalised Prym variety (See Remark 3.7) associated to μ.

Student with special needs often encounter problems where they lack their basic needed skill. These kids face challenges in interacting with the society. These kids often have a low level of social communication. The purpose of this proposed research is to investigate the effectiveness of Multi-Sensory Storytelling (MSST) to improve the social communication of children with special needs/Multiple Disabilities (MD) using technically advanced Virtual Reality (VR) and Computational Intelligence tools. This proposed research work is mainly focusing on age group of 6-10 years old children with special needs. Their levels of communication and life skills have been assessed by standard pre assessment intervention. Based on that customized training strategies on MSST have been formulated using VR techniques and Artificial Intelligent Methods. The experimental sessions have been planned to conduct for a time period of 60mins session for alternate days for twelve weeks course of the duration. The progresses of the customized training programs have been validated through post assessment interventions. The result indicated that among the kids of 20% girls and 80% of boys and the outcomes found to have a gradual improvement (27%) in their social communication with advance technology supported multi-sensory storytelling method. This research work demonstrated by a controlled group of children with autism and their level of improvement has been witnessed. This research work makes the children who live in their own world to lead a normal child; it makes us to treat them both physically and mentally as normal kids to do their day-to-day activities.Keywords

Around the globe, the population suffered with stroke and spinal cord injury are rapidly increasing who are in need of an effective and efficient solution for their day to day life management. Paraplegia is a form of paralysis in which function is substantially impeded from the waist down or lower extremities but not the arms and it is sometimes called as partial paralysis. More than 73% people with paraplegia have perfectly healthy legs. The main aim of this proposed study is to develop an efficient rehabilitation system to treat paralysis patients of paraplegia. In this proposed research work, an assistive knee exoskeleton is designed and developed as a wearable robot with One Degree of Freedom (ODF) movement. This system is attached with the disabled limb with the aim of delivering appropriate motion and pragmatic functionality to the affected knee for suitable rehabilitation. This exoskeleton knee is controlled by the instrumented cane as a wearable sensory system to establish the coordinated movement through patient’s motion task estimation in order to control the trajectory of ODF exoskeleton robot. The computational intelligent control systems provides assisted rehabilitation motion in coherence with the motion of other unassisted upper limbs through the wearable sensors and switches in the instrumented cane. The instrumented cane is a helpful assistive device for rehabilitation in terms of balance and movement for those who suffering neurological disorders, in particular stroke and spinal cord injury. The pilot study on a subject using the proposed system describes utilization of instrumented cane as a feasible interface between the patient and exoskeleton to improve in terms of motion in their day-to-day activities. Also, the system is designed with inertial measurement module integrated with wireless communication device in order to assist real-time control of exoskeleton. The outcomes of the proposed research work validated and appreciated by the expert physicians and therapists. This study strives the purpose of an instrumented cane that able to contribute to the cognitively assisted locomotion technology as well as improves the mobility of physically challenged people.Keywords
