Bio metric surveillance has become indispensable for every system in the recent years. The contribution of bio metric authentication, identification, and screening purposes are widely used in various domains for preventing unauthorized access. A large amount of data needs to be updated, segregated and safeguarded from malicious software and misuse. Bio metrics is the intrinsic characteristics of each individual. Recently fingerprints, iris, passwords, unique keys, and cards are commonly used for authentication purposes. These methods have various issues related to security and confidentiality. These systems are not yet automated to provide the safety and security. The gait recognition system is the alternative for overcoming the drawbacks of the recent bio metric based authentication systems. Gait recognition is newer as it hasn’t been implemented in the real-world scenario so far. This is an un-intrusive system that requires no knowledge or co-operation of the subject. Gait is a unique behavioral characteristic of every human being which is hard to imitate. The walking style of an individual teamed with the orientation of joints in the skeletal structure and inclinations between them imparts the unique characteristic. A person can alter one’s own external appearance but not skeletal structure. These are real-time, automatic systems that can even process low-resolution images and video frames. In this paper, we have proposed a gait recognition system and compared the performance with conventional bio metric identification systems.

Ultrasound imaging is safe, relatively affordable, and capable of real-time performance. This technology has been used for real-time visualization and analyzing the functionality of human organs such as human tongue shape and motion during a real-time speech to study healthy or impaired speech production. Due to the noisy nature of ultrasound images with low-contrast characteristic, it might require expertise for non-expert users to recognize tongue shapes. To alleviate this difficulty and for quantitative analysis of tongue shape and motion, tongue surface can be extracted, tracked, and visualized instead of the whole tongue region. The progress of deep convolutional neural networks has been successfully exploited in various computer vision tasks. This paper presents two novel deep neural network models named BowNet and wBowNet benefits from the ability of global prediction of decoding-encoding models from integrated multi -scale-contextual information and the capability of full-resolution (local) extraction of dilated convolutions. Experimental results using ultrasound tongue image datasets from different ultrasound devices revealed that the combination of both localization and globalization searching could improve prediction result significantly. Assessment of BowNet models in real-time using both qualitatively and quantitatively studies showed their outstanding achievements in terms of accuracy and robustness in comparison with similar techniques.

Droplet as the most elementary substance that comprises spray is very important to investigate in engineering and industrial. The applications examples are in spray cooling and spray coating or painting. Droplet characteristics when pinning onto a surface could be hydrophobic, neutral or hydrophilic. In the present work were modeled and simulated the droplet when attached to the surface using multiphase LBM. The pseudo-potential method was used to treat two-phase substance, and the Carnahan-Starling equation of state (EOS) was used to treat both coexistence substance. The validation was used the spurious current that very important in numerical stability. The results were presented in three conditions: hydrophobic, neutral and hydrophilic.
Function generators are vital tools for many industrial applications. Sinusoidal oscillators are the essential units of function generators and investigating their performance is therefore necessary. The Barkhausen cr...

Thermal radiation influence on conjugate heat transfer is analyzed in a porous medium. The porous medium is assumed to be placed inside the annulus encompassing the two radii of annulus. The porous medium contains a solid object in the form of a vertical wall at inner radius of the annulus. Radiation is approximated using Taylor’s series. The equations are solved numerically using finite element method. Various results such as the fluid flow behavior and temperature contours are presented pertaining to that of geometric as well as the physical parameters.

The heating of an annular vertical cylinder containing porous medium is subjected to non-isothermal power law variation. The physical phenomenon being investigated is in the form of conjugate heat transfer resulting due to presence of a solid at hot surface of annulus. the other vertical surface is maintained at lower isothermal temperature. The results are presented for various values of power law coefficient as well as the width of slid in the domain.
