In this paper we investigate the energetics of level walking trot gaits in quadruped robots with asymmetric body-mass distribution. Two cases of level trotting are considered: constant speed, and deceleration-acceleration with constant average speed. In both the cases, the specific resistance is found to be independent of mass distribution. For the same(More)
Paclitaxel is widely used in the treatment of patients with metastatic breast cancer (MBC). Formulations of paclitaxel contain surfactants and solvents or albumin derived from human blood. The use of co-solvents such as polyoxyethylated castor oil is thought to contribute to toxicity profile and hypersensitivity reactions as well as leaching of plasticizers(More)
This paper puts forward two new evolutionary multi agent based particle swarm optimization algorithms for solving security constrained (line flows and bus voltages) optimal power flows. These two methods combine the multi agents in two dimensional and cubic lattice structures with particle swarm optimization (PSO). All agents occupy in a cubic and square(More)
A delay in diagnosis and management of traumatic rupture of tibialis anterior tendon can lead to chronic ankle pain and instability. Early surgical intervention has been described using extensor hallucis longus (EHL) graft with post operative deficits ranging from abnormalities of early swing phase of gait, stubbing and callosi-ties of great toe. We report(More)
We report a patient presenting with paraparesis with polyneuropathy who later developed haemorrhagic manifestations and multi-organ involvement and seizures. Diagnostic work-up confirmed the diagnosis of leptospi-rosis. The presentation of paraparesis in combination with Weil's syndrome is rare. However, the development of haemorrhagic manifestations and(More)
Sternum fractures are a rare entity and occur either due to direct trauma or indirectly associated to a flexion compression injury. Earlier literatures used to describe the association of sternum fractures with upper thoracic vertebral fractures. To the best of our knowledge very few cases have been described in literature with concomitant lumbar vertebral(More)
