Purpose To determine the characteristics and risk factors for the development of glaucoma after cataract surgery in children seen at a major referral tertiary eye centre in South India. Methods This is a retrospective review of the medical records of consecutive patients seen at the glaucoma/paediatric eye clinic of the centre, with a diagnosis of glaucoma secondary to aphakia/pseudophakia over...
This paper focuses on testing the motor insulation with a secondary insulation made up of polymer nano-composites in addition to the primary one. Twisted pair samples are used to investigate the motor winding behaviour. Modified polyester is the primary insulation here. The primary insulation is subjected to direct testing and the breakdown voltage is determined. Then a secondary insulation layer...
Wireless Sensor Network (WSN) consists of number of sensors for computing the changes in the physical environmental conditions. Subset of nodes can be constructed for the communication in wireless sensor network. This subset of nodes is the Connected Dominating Set (CDS) which will act as a virtual backbone. Virtual backbones are used for the clustering and the routing purposes. Several algorithms...
Disasters create emergency situations and the services provided must be coordinated quickly via a communication network. Mobile adhoc networks (MANETs) are suited for ubiquitous communication during emergency rescue operations, since they do not rely on infrastructure. The route discovery process of on-demand routing protocols consumes too much bandwidth due to high routing overhead. Frequent route...
In a wireless sensor network data from a source is forwarded either in a single hop or multi-hop fashion and most of the nodes energy is depleted while forwarding. The highest priority data is not handled effectively and this forwarding mechanism doesn't suit to industrial application such as industrial boilers where data below the critical levels are important. The rate at which the level decreases...
A performance comparison of an interleaved boost converter (IBC) and the conventional boost converter is presented in this paper. Also this paper investigates the performance of three-phase uncoupled and directly coupled Interleaved Boost Converter (IBC) for renewable energy applications. DC-DC Boost Converters serves many purposes. Low output voltage for renewable energy sources such as Fuel cells,...
