The objective of the present study is to investigate thermal diffusion and radiation effects on unsteady MHD flow past a linearly accelerated vertical plate with variable temperature and also with variable mass diffusion in presence of heat source or sink under the influence of applied transverse magnetic field. The fluid considered here is a gray, absorbing/ emitting radiation but a non-scattering medium. At time t>0, the plate is linearly accelerated with a velocity in its own plane. And at the same time, plate temperature and concentration levels near the plate raised linearly with time t. The dimensionless governing equations involved in the present analysis are solved using the closed analytical method. The velocity, temperature, concentration, Skin-friction, Nusselt number and Sherwood number are discussed through graphs in terms of different physical parameters like magnetic field parameter (M), permeability parameter (K), radiation parameter (R), Schmidt parameter (Sc), Soret number (So), Heat source parameter (H), Prandtl number (Pr), thermal Grashof number (Gr), mass Grashof number (Gm) and time (t).

Fatigue cracking and rutting contribute significantly to the failure of asphalt pavement. In the design of asphalt pavement, it is necessary to investigate these critical strains and design against them. In Nigeria, the only developed design method for asphalt pavement is the California Bearing Ratio (CBR) method. Most of the roads designed using the CBR method failed soon after construction by fatigue cracking and rutting deformation. This study was conducted to develop a modified Nigeria CBR procedure for low volume asphalt pavement adopting the layered elastic analysis procedure which involves selection of materials and layer thickness for specific traffic conditions such that fatigue cracking and rutting deformations are minimized. Analysis were performed for hypothetical asphalt pavement sections using the layered elastic analysis program EVERSTRESS. Regression equations were developed for predicting pavement thickness in cement-stabilized base, low-volume asphalt pavement. The result was validated by comparing calculated maximum fatigue and rutting strains developed using the modified procedure and measured strain data from the Kansa Accelerated Testing Laboratory (K-ATL). The calculated and measured fatigue and rutting strain were calibrated and compared using linear regression analysis. The calibration of calculated and measured fatigue and rutting strains resulted in R2 of 0.999 and 0.994 respectively for subgrade modulus of 31MPa, 0.997 and 0.997 respectively for subgrade modulus of 41MPa, 0.996 and 0.999 respectively for subgrade modulus of 62MPa, 0.992 and 0.995 respectively for subgrade modulus of 72MPa, 0.999 and 0.998 respectively for subgrade modulus of 93MPa, and 0.999 and 0.999 respectively for subgrade modulus of 103MPa indicating that the coefficients of determination were found to be very good.

An unmagnetized dusty plasma consisting of static negatively charged dust fluid, nonthermal distributed electrons, and adiabatic ion fluid has been considered. Basic properties of the dust-ion-acoustic shock waves have been made by the reductive perturbation method to derive the Burgers’ equation for nonplanar geometry. The solution of modified Burgers’ equation in nonplanar geometry is numerically analyzed and it has been found that, the nonplanar geometry effects have a very vital role in the development of shock waves. We also discovered that; the inclusion of the nonthermal electron distribution significantly modifies the shock wave profile. The change of the DIASW structure due to the effect of ion temperature and dust density is studied.

Life Insurance is important for everyone to protect family incase of their demise the insured money will save their family. Our objective of this paper to find out the peak age of people interested to take insurance policy and when they mostly use the benefits in their policy period. It has been classified into six benefitst. To study this problem, they divided and defined four types of matrices. Now we use this model to study of the people interested to take insurance policy and when they mostly use the benefits in their policy period.

This paper investigates the development of Al6061/Si3N4 metal matrix composites using stir casting technique and optimize the process parameters in turning based on Genetic Algorithm. In this metal matrix composites Al 6061 alloy reinforced with 3% and 5% weight by volume of Si3N4 particles of mean diameter 75µm was used. Experiments were performed in the CNC lathe by using CNMG inserts at various cutting conditions and parameters such as cutting speed, feed and depth of cut and surface roughness was found at different levels. The optimization of machining parameters was done by using Genetic Algorithm.
