The need and drive for sustainable development have never been greater. This creates demand for radical ways to improve efficiency and resource productivity. This paper describes how integrating the Internet of Things (IoT), Big Data and Cloud computing creates a recipe for driving sustainable development and growth. Issues and challenges associated with IoT technology are explored and a framework...
This paper considered multiuser orthogonal frequency multiple access (OFDMA) scheme, which has been proposed as the transmission technique for 4th Generation (4G) cellular network. An optimum and dynamic radio resource (subcarrier and power) allocation scheme is proposed for OFDMA multiuser system. The proposed algorithm has considered a structured degree of flexibility among the services that can...
In this paper, the design of a subspace compressive GLRT (SSC-GLRT) detector has been pursued for MIMO airborne radar system when the secondary sets of data are available in addition to the primary one. It is observed that with very reduced amount of measurement data at sub-Nyquist rate that is equal to the number of virtual bi-static radar in the presence of a single target, SSC-GLRT provides the...
In this paper, a generalized model is proposed to analyze the impact of propagation environment and velocity on the handover performance of user equipment (UE) for long term evolution (LTE) systems. An adaptive time window is defined within the generalized model, to provide additional flexibility to perform handover procedure over conventional reference signal received power (RSRP) and reference signal...
In this paper, a geometrically based 3-D propagation model is presented for macrocellular land mobile radio channel with a mobile station (MS) located at the center of a 3-D scattering semi-spheroid and a base station (BS) employing a directional antenna located outside of the semi-spheroid. The effect of directional antenna is thoroughly observed on the spatial characteristics seen at MS. Closed-form...
To evaluate dry hot air effect as a reliable method of disinfection of urological endoscopes.Two groups of urological endoscopic instruments (2 cystoscopic sheaths, 2 bridges, and 2 working elements of resectoscope and urethrotome for each group), after being sterilized by full immersion in 2% glutaraldehyde solution for 10 hours, were contaminated by immersion in suspensions of Staphylococcus saprophyticus...
