Increasing power requirements lead the way for the development of new innovative ideas to generate electricity like the introduction of solar power satellites. This system consists of a number of satellites such that the maximum solar energy is collected. This energy is then converted to electromagnetic beams and transmitted to Earth wirelessly. Simultaneous wireless power and data transmission is...
The paper describes an Energy — Efficient Resource Allocation protocol for Wavelength-Routed All-Optical WDM Networks. Protocol selects efficient and low power consumption optimal primary and backup paths. The path selection will be done by Central Management System (CMS). The selection will be by two methods, i.e., the path with less number of free wavelengths will not be considered for selection...
Appropriate to fractional hardware and connectivity harms, picture dispensation on movable elegant cell phone is a fresh and pitiful ground by lots of plucky. Android supported cell headsets be currently enticing a center of some application. Here manuscript describes precise instance facade identification request replica used for chic receiver. Here initiate mold employ mixture skin hue-sentiment...
Conceptual Segmentation is a critical technique in medical imaging. The Processes of identification and division of optic circle and veins are the fundamental strides for the analysis of a few infections that causes visual deficiency like diabetic retinopathy, hypertension, glaucoma and different visual deficiency ailment. These diseases lead to loss of vision. The vein data is required or used to...
In present time due to increase in number of kidnapping and road accident cases, parents always worry about their children. This paper recommends a SMS based solution which assists parents to track their children location in real time. To track the location GPS module is used and to identify the identity of the child a RFID card is used which is in built in the system. Whenever a child boards a bus,...
In recent years of digital world, a lot of interest has been emerged in the optical fiber. In this paper, we are modelling the spectral attenuation and central dip in refractive index profile parameters in an optical fiber. The feasibility and practicability of modeling and analysis of the spectral loss of an optical fiber is performed using an algorithm to a single multi-parameter equation. In that,...
Compact Branch line and Rat-race coupler are analyzed and designed using Artificial Transmission Line (ATL). The couplers are designed to operate at center frequency of 2.5GHz using commercially available FR4 material. Properties are analyzed using IE3D simulation tool. Conventional couplers are also analyzed for comparison purpose. Couplers using ATL show 40% size reduction compared to conventional...
In this paper, we present the characterization of the Ring oscillator for submicron technology in terms of the first order design equations of the MOSFETs, and we arrive at the extent upto which the short channel effects influence the oscillating frequency. In addition, a solution is suggested to reduce the duration of metastability upto 50%. The Ring oscillator is designed from 3-stage till 15-stage,...
A field-programmable gate array (FPGA) is an integrated circuit. It is known as System on programmable chip (SOPC) The FPGA configuration is generally specified using block diagramme representation and “VHDL”. Quartus-II can be interface with Nios-ii software tool. In that, “C-Programming” can be used for Modbus Communications, In Nios-II, with use of UART, CRC, function codes, timer and Frame receiving,...
Image coding for high resolution representation, with projection edge smoothening with less computation time is been proposed in this work. This paper considers the main factors that affect the image projection, speed and accuracy respectively. In this paper a new hybrid system was proposed for image projection. It incorporates the bi cubic interpolation for efficient image projection, an adaptive...
Security in Wireless Sensor Network (WSN) has become a key issue due to demanding areas in which WSNs are being applied. With scarce resources in sensor nodes seasoned techniques like Diffie-Hellman, RSA and elliptic curve cryptography (ECC) cannot be used because they have resource demanding computations. Key pre-distribution has proved to be the most feasible amongst key management schemes in WSNs...
The Normalized Difference Vegetation Index (NDVI) is one of the most widely used numerical indicator that uses the visible (VIS) and near-infrared bands (NIR) of the electromagnetic spectrum, and is utilized to analyze remote sensing images and assess whether the target contains live green vegetation or not. This paper analyses the utility of NDVI for mapping the land cover characteristics over Tirupati...
This paper deals with the designing an interface between AXI Protocol based system and DDR3 Memory. It enables an AXI host to read and write data in a DDR3 Memory. It has been designed to utilize the DDR3 interface for maximum throughput. It implements FIFO where it stores the write command and writes data and passes it to DDR3 Memory. Similarly, it collects data from DDR3 Memory and stores in a FIFO...
JPEG is widely accepted standard for image compression. JPEG image compression makes use of quantization table to control the compression ratio and quality of compressed image. Hence, generation of quantization table for the JPEG baseline algorithm is viewed as an optimization problem. For the past few decades, methods used for determining the quantization table have been based on Rate-distortion...
Data transmission through the internet is popular in contemporary world. What is of utmost importance is secrecy as well as data privacy in the communication channels of the internet. Steganography consists of by far the best techniques for data hiding and ensuring secrecy. This paper focuses on audio steganography, where a message audio file is embedded within another cover audio file.
Now-a-days the research in the field of wireless communication increased rapidly. Proportionately the antenna research grows day-by-day. Fractal antenna design has created a major role due to its compactness as well as wider application in UWB application. In this paper Koch iteration technique has been utilized to obtain a reduced size antenna. The sierpinski carpet is inserted into the triangular...
This paper proposes a frequency reconfigurable pixel patch antenna for Cognitive radio applications. A single patch antenna is designed and simulated for a frequency of 10 GHz. identical patches are then connected lengthwise and widthwise to the designed single patch. Henceforth the concept is used for the design of a 3×3 pixel patch antenna. The proposed reconfigurable antenna consists of a grid...
A ZigBee communication technology is established recently for several smart electric grid applications like Home Energy Management Systems (HEMS), Electric Vehicles (EVs), wireless automatic Metering, load control, fault detection and power outages. Analysis is done to investigate the performance of ZigBee in terms of throughput, packet delivery ratio, average delay and energy consumed in various...
