The paper explores the usefulness of hybridizing two distinct nature inspired computational intelligence techniques viz., Artificial Neural Networks (ANN) and Genetic Algorithms (GA) for modeling slump of Ready Mix Concrete (RMC) based on its design mix constituents viz., cement, fly ash, sand, coarse aggregates, admixture and water-binder ratio. The(More)
Objectives : To find out the feasibility and yield of endometrial sampling as an OPD procedure using a suction curette device for evaluating abnormal uterine bleeding in pre and post menopausal women. Methods: Endometrial biopsy was done in the OPD without anesthesia, on 50 consecutive patients of pre and post menopausal age group, presenting with symptoms(More)
Cement concrete is widely used throughout the world as a key construction material in civil engineering projects. Being a complex compound comprising of cement, sand, coarse aggregate, admixture and water, its compressive strength is a highly nonlinear function of its constituents, thereby making its modeling and prediction a difficult task. Nature inspired(More)
OBJECTIVE -To find out the role of colposcopy and colposcopy directed biopsy in evaluation of entire lower female genital tract in symptomatic women. METHODS Colposcopy was carried out on 175 consecutive, referred patients who presented with symptoms like vaginal discharge, postcoital bleeding and post-menopausal bleeding or were found to have abnormal(More)
The field of engineering is a creative one. The problems encountered in this field are generally unstructured and imprecise influenced by intuitions and past experiences of a designer. The conventional methods of computing relying on analytical or empirical relations become time consuming and labor intensive when posed with real life problems. To study,(More)
Two main forces behind a lot of interest in the OCDMA techniques are the ability to support asynchronous, bursty data transmission and data access security. To achieve high speed connectivity with a large bandwidth, OCDMA is a highly flexible technique. This paper describes a simulated system for an incoherent OCDMA system using high performance 2-D codes.(More)

Artificial Neural Networks (ANN) trained using backpropagation (BP) algorithm are commonly used for modeling material behavior associated with non-linear, complex or unknown interactions among the material constituents. Despite multidisciplinary applications of back-propagation neural networks (BPNN), the BP algorithm possesses the inherent drawback of(More)
