This paper studies the application of system reliability theory with certain modifications to a four lane highway. It can be modeled the four lane highway as a series parallel system. To analyze traffic accident frequency and reliability of each Lane, we generated number of accidents in each section by using simulation technique. Assuming that the time between two accidents will follow an exponential distribution, we determined reliability and accident frequency of each Lane along with its sections. Based on the results obtained conclusions were drawn.Keywords

Numerical investigation of the transient natural convective double diffusion in a Walter-B viscoelastic fluid from a vertical cone with electric conductivity is introduced. Numerical analysis for non dimensional concentration, velocity and temperature fields by utilizing implicit finite difference scheme have been studied for the effect of electric conductivity parameter, Prandtl number (Pr), viscoelasticity parameter. The present discussion fixates on the local Nusselt number skin-friction and Sherwood number. It is observed that the electric conductivity has critical impact on the effect on the viscoelastic fluid flow past vertical cone proximate to the cone surface. Our numerical conclusions are compared with anterior work and a good acquiescent is descried.Keywords

The field of mathematics plays a vital role in various fields. One of the most important areas in mathematics is graph theory. Graph coloring arises naturally in a variety of applications such as register allocation and timetable, examination scheduling, map coloring, radio frequency assignment, pattern matching, Sudoku, telecommunication and bioinformatics. Graph coloring problem is a combinatorial optimization problem applicable in many problems existing nowadays. To solve the graph coloring problem, Genetic Algorithm, a calculus free optimization technique based on principles of natural selection for reproduction and various evolutionary operations such as crossover and mutation is used. Many algorithms are available to solve a Graph coloring problem. A recent and very promising approach is to embed local search into the framework of Evolutionary algorithm. This approach of hybridization is very powerful and these algorithms are carried out on large DIMACS challenge benchmark graphs. The results are very competitive and even better than those of state of the art algorithms. This paper focuses on reviewing the recent literature on hybrid genetic algorithm, and recommending state of the art algorithm in GCP.Keywords

This problem deals with the theoretical study of Jeffrey fluid flow through an inclined tube with overlapping stenosis. The nonlinear equations are simplified by considering mild stenosis. The exact solutions are obtained for velocity, pressure drop, flow rate, resistance to the flow and wall shear stress. Effects of different physical parameters like Jeffrey fluid parameter and angle of inclination on resistance to the flow and wall shear stress are studied. The effects of various emerging parameters are discussed through graphs for different values of interest.Keywords
