AIMS To compare the prevalence of diabetic retinopathy (DR) in people of various ethnic groups with diabetes in the United Kingdom (UK). METHODS The Diabetic Retinopathy In Various Ethnic groups in UK (DRIVE UK) Study is a cross-sectional study on the ethnic variations of the prevalence of DR and visual impairment in two multi-racial cohorts in the UK.(More)
This paper proposes a classification-based face detection method using Gabor filter features. Considering the desirable characteristics of spatial locality and orientation selectivities of the Gabor filter, we design filters for extracting facial features from the local image. The feature vector based on Gabor filters is used as the input of the classifier,(More)
In this paper we present a new fault-tolerant di-the nodea of the network, which communicate among themselves by exchanging messages only. We have shown that our algorithm functions properly when any of the cooperating nodes in the system fails. The communication delay may vary but haa an upper limit of A time units and the messages are not guaranteed to be(More)
—Utilization of wearable textile materials for the development of microstrip antenna segment has been rapid due to the recent miniaturization of wireless devices. A wearable antenna is meant to be a part of the clothing used for communication purposes, which includes tracking and navigation, mobile computing and public safety. This paper describes design(More)
– Differential evolution (DE) algorithm is used to design a microstrip antenna, loaded with a shorting pin. The position of probe and the position of shorting pin are optimized using DE. The fitness function for DE is obtained using multiport network modelling technique. Antenna is fabricated and measured results are compared with the theoretical results.
In this paper, we have proposed two recovery algorithms for distributed systems. Both algorithms follow a revolving centralized scheme. The direct dependency tracking of an integer representing the number of messages sent by each process has been shown to be sufficient to determine the maximum consistent state. The main feature of the recovery algorithms is(More)
