The aim of the paper is to give a collection of some important concepts of queuing theory and their applications. Queuing theory is the mathematical study of waiting lines that enables mathematical analysis of several related processes, including arriving at the queue, waiting in the queue, and being served by the Service Channels at the front of the queue. Queuing theory examines every component of waiting in line to be served, including the arrival process, service process, number of servers, number of system places and the number of customers. Also the author gives notations used for queuing models and characteristics of queuing theory. Queuing models can help in balancing the cost related to capacity planning of service system and the cost incurred due to waiting time of customers.

This monograph provides an epistemological rational for the Post Hoc Trichotomous Progression Analysis of the transformative process of qualitative data into quantitative outcomes through the Tri–Squared Test introduced in i-manager’s Journal on Mathematics, and further expounded and detailed in the Journal on Educational Technology, Journal on School Educational Technology, and in Journal on Educational Psychology. This particular advanced statistical metric is designed to measure the predictive outcomes of the outcomes of a significant Transformative Trichotomy–Squared [Tri–Squared] Test. To further explain the Trichotomous Progression Analysis mathematically, “Proximal Positive Parallel Notation” (a novel mathematical notation is used to define the relationship between values)is used to construct the Trichotomous Progression Line. The Progression Line describes the attributes of the Post Hoc significant outcomes as values that describe a specific set of Tri–Squared Test results. This novel approach to advanced Tri–Squared research as an advanced data analysis methodology adds additional value, breadth, and depth to the Tri–Squared mixed methods approach by further enhancing and adding to the rigor of trichotomous research design. Multiple sequential mathematical models are provided that illustrate the methodology used to determine advanced trichotomous progression inquiry.

The effect of radiation on MHD free convection three dimensional flow in a vertical channel filled with porous medium has been studied. The authors have considerd an electrically conducting incompressible viscous fluid in a parallel plate channel bounded by a loosely packed porous medium. The fluid is driven by a uniform pressure gradient parallel to the channel plates and the entire flow field is subjected to a uniform inclined magnetic field of strength H inclined at an 0 angle of inclination a with the normal to the boundaries in the transverse xy-plane. The temperature of one of the plates varies periodically and the temperature difference of the plates is high enough to induce radiative heat transfer. The effects of various parameters on the velocity profiles, the skin friction, temperature field, rate of heat transfer in terms of their amplitude and phase angles are shown graphically.

This work is focused on the non linear MHD flow heat and mass transfer characteristics of an incompressible, viscous, electrically conducting and Boussinesq fluid over a vertical oscillating porous permeable plate in presence of homogeneous chemical reaction of first order, thermal radiation and soret effects. The problem is solved analytically using the perturbation technique for the velocity, the temperature, and the concentration field. The expression for the skin friction, Nusselt number and Sherwood number are obtained. The effects of various thermo-physical parameters on the velocity, temperature and concentration as well as the skin-friction coefficient, Nusselt number and Sherwood number has been computed numerically and discussed qualitatively.

This paper analyzes the Dufour and Soret effects on the MHD flow with heat and mass transfer on flow past an oscillating infinite vertical plate with variable temperature and variable mass through porous medium. The dimensionless governing partial differential equations are solved by using finite difference method. The velocity, temperature and concentration profiles are considered for different physical parameters. The results are analyzed through graphs and tables. It is observed that the velocity profiles increase through increase in Dufour (Du) and Soret (Sr) numbers and decrease with increase in permeability (K) and suction parameter (V ). An increase in increase in Du, leads to increase 0 in the temperature. The concentration profiles increase with increase in Prandtl (Pr) and Soret numbers, wt and decreases through increase in Schmidt number (Sc), , Du, and also with suction V . The shear stress increases with 0 increase in modified Gr, K, Ec, Du, Sc, V and decreases through an increase in Hartmann (M)and Grashof (Gr) numbers, 0 Pr, Sr, and . Increase in M, Gc, K, Pr, Sr, and V causes decrease in the rate of heat transfer and increase in Gr, Ec, Du, , 0 and Sc leads to increase in the rate of heat transfer. The rate of mass transfer increases through an increase in M, Gr, Gc, K, Pr, Du, and V and decreases with an increase in Ec, Sr, , and Sc. In the absence of suction, viscous dissipation, and 0 mass transfer, the results obtained were good agreement with Sarswat and Srivastava (16). The graphs are drawn to show the comparative study.
