Abstract: Acceptance sampling plans are introduced mainly to accept or reject the lots of finished products. There are several techniques available to control the quality. Some of the techniques are popularly used where testing involves destruction, for instance, in the manufacturing of crackers, bullets, batteries, bulbs and so on, it is impossible to go for 100% inspection. In this paper we optimized CASP-CUSUM Schemes based on the assumption that the continuous variable under consideration follows a Truncated Dagum Distribution. It is used the Lobatto Integration..............

Keywords: CASP-CUSUM Schemes, type-C, OC Curve, ARL, Truncated Dagum distribution.

Abstract: This study presents a graph theoretical approach to identify the traffic congestion on a road network. Problem address on a city called Kiribathgoda situated in the western province of Sri Lanka. In the analysis of social networks, centrality measures played a vital role to identify the central nodes in a given network. We look at the applicability of centrality and betweenness measures in order to identify the most important locations which directly affect to the traffic congestion in road networks in Sri Lanka. Using the graph theoretical approach a traffic network for a selected area was constructed and several centrality measures were calculated. According to our simulation results, it was noted that the practically identified locations could be identified from the simulations carried out using the centrality measures.

Abstract: An analysis to study the unsteady free convective heat transfer due the combined effects of buoyancy, radiation and transverse magnetic field is carried out for an infinite vertical plate in a porous medium. The dimensionless governing coupled partial differential boundary layer equations are formulated and solved analytically using the Laplace transform technique. Results are compared with previous works and found in agreement. The effects of the parameters that enter the problem are discussed.
