Incubator Analayzer With Automatic Shutter Opener
Authors: G. Gnancy Subha, M. Fazilath
Abstract
The purpose of the paper is to design an incubator analyzer with automatic shutter opener. Incubator is the most common device that can provide an environment where preterm babies can healthily grow in. We place premature or sick babies inside an incubator to help them maintain their temperature. The primary function of this system is to monitor temperature, toxic gas, humidity and position of the infant present inside the incubator. The data collected by these sensors are sent to the Arduino Microcontroller. The data are then transmitted to the user through microcontroller. Here the system uses IOT (Internet of things) to transmit the information. From the transmitter, the recordings of infant parameters are sent as messages to the recipient through IOT. When the condition is abnormal the alarm buzzer alerts the care taker and sends an emergency message. When the incubator is filled with toxic gas, it is automatically removed by shutter open /close.

Abstract
Due to the development of the Internet, security and intellectual property (IP) protection have involved significant feature in the copyright protection field in recent times. The audio watermarking is generally used as a multimedia copyright protection tool. In this paper, we present a watermarking algorithm and its VLSI architecture that can insert a CSS signal in real-time to smooth the progress of copyrighted audio signal. Robust audio watermarking plays a most important role for the development of militaries, RADAR and wireless communication. The watermark is a method of embedding information into digital content by adding a signal to the content data. The process of embedding information into an audio signal is called audio watermarking. The system is initially prototyped and validated in MATLAB/Simulink and subsequently implemented in Vertex 4-XC4VLX25- 10FF668 FPGA device using Xilinx system generator, the generated VHDL code is synthesized in Xilinx ISE 12.1. The experimental results demonstrate that the proposed watermarking scheme obtains good robustness and conserve imperceptivity.

Abstract
Single crystals of La(III)- doped ammonium dihydrogen phosphate (ADP) and tris(thiourea)zinc(II) sulfate (ZTS) are grown by conventional slow evaporation of aqueous solution technique. Morphological changes are observed in the doped specimen. Doping has some influence on the DRS spectra and the band gap energy is estimated by Kubelka–Munk algorithm. Incorporation of La(III)- into the crystal lattices were well confirmed by energy dispersive X-ray spectroscopy (EDS) and atomic absorption spectroscopy (AAS). The lattice parameters of the as-grown crystals were obtained by single crystal X-ray diffraction analysis. The reduction in the intensities observed in powder X-ray diffraction patterns of doped specimen and slight shifts in vibrational frequencies in fourier transform infrared spectra (FT-IR) indicate the lattice stress as a result of doping. Thermal studies reveal the purity of the material and no decomposition is observed up to the melting point. The second harmonic generations (SHG) efficiency of the host crystals are enhanced greatly in the presence of the dopant.
Controller Design for a Nonlinear SISO Framework using Adaptive Backstepping Technique
Authors: Samiran Maiti, Achintya Das
Abstract
This paper represents an adaptive controller design for a nonlinear Single Input Single Output (SISO) framework. At the outset of the design, the state space structure of a SISO framework has been presented. Subordinate upon the changes of structure elements like friction coefficients, knot inactivity, an adaptive backstepping strategy has been used to devise a versatile control for a nonlinear system. Further, the performance of the framework can be ensured by reasonably selecting the Lyapunov stability theory to develop the controller. The adequacy of the proposed adaptive controller is shown with the MATLAB Simulation.
Fault Detection and Protection of Transmission Line by Using Distance Relay
Authors: Mr. Mayurkumar M. Patel, Mr. Vishnu B. Patel, Ms. Kripa H. Patel
Abstract
Electrical power systems are becoming increasingly sophisticated as the demand for electricity grows. Transmission line protection is essential for improving the dependability of the power system and restoring power utility services. Because transmission lines are constantly prone to severe types of faults, many protective techniques have evolved for effective transmission line protection. Various types of distance relays are used for the protection of a transmission line. In this paper simulation of the mho relay for a long transmission line is prepared. The simulation is done with MATLAB/Simulink and results were compared for various types of faults. The comparative analysis of tripping of a circuit breaker is done for the different types of the fault occurring at various locations on the transmission line.

Authors: Thirumalesha T, Mrs.Meghashree A C, Dr.G.F.Ali Ahammed
Abstract
This paper describes a brain controlled robot based on Brain–computer interfaces (BCI). BCIs are systems that can bypass conventional channels of communication (i.e., muscles and thoughts) to provide direct communication and control between the human brain and physical devices by translating different patterns of brain activity into commands in real time, with these commands a mobile robot can be controlled. In this paper the brain wave signals are analysed and on the basis of Eye-Blink counts, the direction of the robot is controlled. The basic idea of BCI is to translate user produced patterns of brain activity into corresponding commands . It this experiment, Brain sense is interfaced with the Mat lab to get streaming on EEG packets and to do processing extract the Blink waves and fed control command to the Arduino for movement of the car via Bluetooth. So this project acquires 3 process. Signal acquisition – Acquiring EEG packets from the Brain sense Signal Processing – Mat lab is used for processing the signal and to extract the Eye blink signal Application – After classifying the signal, car movement can be decided based on GUI that where you made blink.
