Application of Simulation Technique in Queuing Model for ATM Facility

Author(s)– Vasumathi.A, Dhanavanthan P

Abstract
ATM is an automatic teller machine which is used to save the cost and reachability of a bank by satisfying customer needs. Customers can withdraw and deposit money without any paper work and it facilitates them to reduce time and cost to go to bank in person. By considering the utility of ATM services of different banks at global, the authors adopted simulation technique for identifying the pitfalls of existing 3 ATM services of 3 different banks at VIT (Vellore Institute of Technology) and also planning to propose a new ATM service from any one of these banks or other than the existing banks based upon the service required from the customers. The authors formulated a suitable simulation technique which will reduce idle time of servers and waiting time of customers for any bank having ATM facility. This technique will be helpful for any bank at global for improving their customer’s service towards competitive advantage.

Application of Regional Climate Model Simulation and Flow Data for Assessing Future Water Availability in the River Jamuna
Author(s) – Mohammad Adnan Rajib et.al.,

ABSTRACT

Among the multifarious dimensions of climate change, alteration of precipitation pattern with associated changes in runoff and subsurface flow, rise in surface temperature and consequent increase in evaporation rate are sure to have direct impact on the future water availability of major river systems in Bangladesh like the Jamuna. The characteristic trends of historical river-discharge data, as developed in this paper, indicate that the river Jamuna has undergone a generous amount of amplification of flow through the years. Subsequently, this increase can be attributed to the effects of climate change mainly in terms of extensive precipitation on the river-catchments and rise of water level by inflating snow-melt at its source as a result of the global warming. However, the main objective of this paper is to develop and analyze the characteristic trends of average monthly flow of the river Jamuna in Bangladesh using historical records, and to correlate the hydro-meteorological water-balance as calculated from the climate model projections of precipitation and evaporation, which would therefore aid the assessment of climate change impact on the future possible flow condition and water availability in the Jamuna River system.

Simulation of Wetted Surface Area of a Single Seater Home Based Aircraft

Author(s)– VENKATESAN.M

Abstract
To simulate the wetted surface area for the various components of the single seater home built aircraft using “C”. Aircraft wetted area (Swet), the total exposed surface area, can be visualized as the area of the external parts of the aircraft that would get wet if it were dipped into water. The wetted area must be calculated for drag estimation, as it is the major contributor to friction drag. The wetted area is estimated by multiplying the true- view exposed as plan form area (Sexposed) times a factor based upon the wing or tail thickness ratio. If a wing or tail were papper-thin, the wetted area would be exactly twice the true plan form area (i.e. top and bottom). The effect of finite thickness is to increase the wetted area, as approximated. Note that the true exposed plan form area is the projected (top-view) area divided by the cosine of the dihedral angle.
