The finite-amplitude instability of the buoyancy-driven boundary layer is considered on a vertical plate immersed in thermally stratified ambient medium, where wall and surrounding fluid have different temperature gradients. Although linear stability this configuration has been investigated, solution arising from critical studied only for specific parameter values. We extend by using amplitude ...

The initial growth of mycobacteria from 49 samples of cattle and buffalo organs collected in commercial slaughterhouses was compared between modified Middlebrook 7H11 thin layer microcolony culture and Stonebrink medium used in the isolation of Mycobacterium bovis. Aliquots were decontaminated by Petroff's method, processed and cultured in both media. The identity of the acid-fast bacilli stain...

A software defined ZigBee receiver has been designed, implemented and tested with a commercially available offthe-shelf ZigBee transceiver. This system is based on the software defined system-in-package (SIP) platform by Harris Corporation (Melbourne, Florida, USA). This platform is equipped with a high-resolution analog-to-digital converter (ADC) and four Xilinx Virtex-4 FPGAs. An alldigital p...

The eggs of Dactylobiotus dispar, similar to other Tardigrada eggs, are covered with two shells: the vitelline envelope and the chorion. Ultrastructural studies have shown that the oocyte actively participates in the formation of both shells. The process of egg capsule formation begins at the midpoint of vitellogenesis. The chorion at first appears as isolated cones resulting from the exocytoti...

Scenario Configuration  Complex system of multiple sensor nodes Ambient intelligence used to monitor physiological data WBAN simulation:  is essential before deployment in real world scenarios  is useful in studying energy efficiency requirements and application behavior  models the behavior of the medium access control (MAC) layer behavior which supports radio use of the physical (PHY) l...

In this talk we present a continuum model and numerical results for transient flows over and through porous media. First, we briefly discuss the derivation of the model and present an algorithm for its numerical treatment. Subsequently, we present results from direct numerical simulations for developing flows over porous layers of large porosity. Due to the steep velocity gradients across the i...

This document describes priority flow control (PFC), one of the functions of IEEE 802.1 Data Center Bridging, introduced to address reliability at Layer 2 on the Ethernet medium. PFC enables lossless semantics for a subset of the Layer 2 flows carried on an Ethernet segment. The subset of flows subject to the lossless semantics is identified by the IEEE 802.1p class of service (CoS) information...

In mobile Internet, a handover may result in significant degradation of transmission performance. Especially in a shared medium wireless network, handover traffic which moves into a new wireless access network competes with existing traffic for available bandwidth of shared medium wireless channel. This interaction between handover traffic and existing traffic causes significant performance deg...

Wireless ATM (WATM) aims at providing transmission of different type of traffics such as voice, data and video over wireless medium. It takes advantage of high bit rate and Quality of Service (QoS) guaranteed data transfer that is already well achieved by ATM technology in wired medium. A WATM MAC layer is employed to effectively utilize the shared wireless medium resources by multiple users. T...
