Abstract: In this paper we discuss the effects of combined convection flow of a viscous incompressible fluid past an infinite vertical porous plate embedded with highly porous medium with periodic permeability under constant heat flux in presence of slip boundary conditions for velocity. The velocity and temperature are obtained analytically and their behaviour for different variations in the governing parameters are shown graphically and discuss numerically. The skin friction and Nusselt number are also evolved analytically and tabulated numerically for variations in the said parameters

Abstract: The advent of Bluetooth technology has made wireless communication easier. Bluetooth as a technology has evolved a lot over the years. Security in any area is given more importance as it leads to better product and satisfied customers. Bluetooth security has evolved a lot with different versions of blue tooth. Keeping in mind the growing list of Bluetooth products in the market, there has been lot of improvements done in the version 4.0 of Bluetooth. The LE (Low Energy) operational mode which is new in version 4.0 has slightly different security features. In this paper, an overview of the Low Energy security aspects is presented. The different security modes, authentication, authorization procedures and data signing procedure are discussed in detail. The paper concludes by listing the ramifications of low energy enhancements in Bluetooth
