Aspects of large-scale organized structures in sink flow turbulent and reverse-transitional boundary layers are studied experimentally using hot-wire anemometry. Each of the present sink flow boundary layers is in a state of perfect equilibrium or exact self-preservation in the sense of Townsend (The Structure of Turbulent Shear Flow, 1st and 2nd edns, 1956, 1976, Cambridge University Press) and Rotta (Progr. Aeronaut. Sci., vol. 2, 1962, pp. 1-220) and conforms to the notion of pure wall-flow (Coles, J. Aerosp. Sci., vol. 24, 1957, pp. 495-506), at least for the turbulent cases. It is found that the characteristic inclination angle of the structure undergoes a systematic decrease with the increase in strength of the streamwise favourable pressure gradient. Detectable wall-normal extent of the structure is found to be typically half of the boundary layer thickness. Streamwise extent of the structure shows marked increase as the favourable pressure gradient is made progressively severe. Proposals for the typical eddy forms in sink flow turbulent and reverse-transitional flows are presented, and the possibility of structural self-organization (i.e. individual hairpin vortices forming streamwise coherent hairpin packets) in these flows is also discussed. It is further indicated that these structural ideas may be used to explain, from a structural viewpoint, the phenomenon of soft relaminarization or reverse transition of turbulent boundary layers when subjected to strong streamwise favourable pressure gradients. Taylor's frozen turbulence hypothesis is experimentally shown to be valid for flows in the present study even though large streamwise accelerations are involved, the flow being even reverse transitional in some cases. Possible conditions, which are required to be satisfied for the safe use of Taylor's hypothesis in pressure-gradient-driven flows, are also outlined. Measured convection velocities are found to be fairly close to the local mean velocities (typically 90% or more) suggesting that the structure gets convected downstream almost along with the mean flow. © 2010 Cambridge University Press.

The use of natural fibers and bio-particles as reinforcement in polymeric composites is gaining keen interest in the field of cellulose based composite materials, due to its attractive properties such as light weight, low cost and biodegradability etc. Several studies in the past have reported major improvement in the mechanical behaviors of fiber reinforced polymer composites by impregnating bio-particulate with the matrix system. This investigation is aimed at introducing a hybrid reinforcement based polymer composites which uses rice husk as bio-particles and green husk coir as fibrous reinforcement. The composite sheets were fabricated as per full factorial design of experimental plan by varying the fabrication parameters namely fiber length, fiber content and particulate content. The effects of fabrication parameters on the impact properties of the composites were analyzed and favorable conditions to yield better impact strength were determined. The X-ray diffraction and Scanning electron microscopy techniques were used to characterize the bindability of rice husk and coir fibers in the resin system. A major improvement in the impact properties was inferred on impregnating rice husk bio-particles in coir-vinyl ester composites. © 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Source

Speech has always been one of the most important carriers of information for people and has become a challenge to maintain its high quality. Acoustic Noise Cancellation (ANC) has gained much attention as a technique to remove noise in speech signal and enhance its quality. When the speech signal and noise both change continuously, then arises the need for adaptive filtering. The heart of the adaptive filter is the adaptive algorithm, which converges rapidly to the changes in the input signal. Least Mean Square (LMS) algorithm is easy to understand and implement, stable and robust but has a disadvantage of slow rate of convergence and gradient noise amplification. Hence Normalized Least Mean Square (NLMS) algorithm is used which provides variable step size to increase convergence speed. Recursive Least Squares (RLS) algorithm is used when high convergence speed is expected. These algorithms are simulated using MATLAB and Simulink and then realized on TMS320C6713 board. Performance of these algorithms is compared using parameters like Signal-to-Noise Ratio (SNR), Mean Square Error (MSE), Misadjustment and Convergence time. © 2015 IEEE. Source

The critical issue in elections is choosing a leader who will represent his nation and preserve its citizens' rights with the threat of a criminal element attempting to influence the outcome of the election. Unfortunately, such disruptions have occurred at many paper-based voting stations, and also in some electronic voting systems. Manual, or paper-based voting is the most widely used voting system, but its integrity can be questioned, since the votes are gathered and counted by hand, which decreases the likelihood of every vote being counted, either accidentally or intentionally. Electronic voting systems have emerged to solve most of the problems that occur in manual voting. However, the criminal element, with their knowledge of how to exploit technical loopholes, attempts to take advantage of these problems, thwarting any efforts to hold fair elections. To avoid the mistakes made by both manual and electronic voting systems, we have developed the M-Vote system to try to achieve the desired goal, which is to preserve the integrity of elections. M-Vote is a mobile phone application that uses three level of security, which are username and password, national ID and fingerprint, and a strong dedicated security algorithm. These techniques prevent votes from being deleted or changed, enhance integrity and put an end to criminal acts. The results showed that M-Vote is a highly secured mobile application that facilitates the vote process for most of people, since they only need a mobile phone and an Internet connection to participate in the election process. © 2013 IEEE.

This paper presents the design simulations of MEMS based micro-cantilever beam made up of PDMS properties using COMSOL Multiphysics. The cantilever beam structure on fluid Channel has been simulated. The simulations results into the stress, displacement, The study brings out a novel methodology for detection of pathogens at minute level.
