The evolution of level set segmentation needs an appropriate initialization and controlling parameters, which requires manual intervention. A new spatial fuzzy level set algorithm is proposed in this paper to facilitate the automatic mammogram image segmentation. The initial segmentation of the mass is obtained by spatial fuzzy clustering that incorporates the spatial information and local intensity...
This paper describes approach based on the particle swarm optimization with improved inertia weight approach (PSOIIW) to improve nulling performance of time modulated linear antenna arrays by Radio Frequency (RF) switch. The nulls position of a time modulated linear array can be reduced significantly by rearranging the static excitation amplitudes as well as the wtich-on intervals of each element...
Present era of SOC's comprise analog, digital and mixed signal components housing on the same chip. In this environment processor plays a vital role. As the technology shrinking to sub-micrometer technology node, there exists a huge scope of undesirable hazards in processors. These hazards may lead to disturbance in area, power and timing which deviate from desired quantities. Our paper focuses mainly...
A normal burglar alarm system typically comprises only a local system and an on-site burglar alarm. In this implemented model, system consists of a remote system present in a cloud and a local system interacting with it for authentication and alarm purposes. Both on site alarm and an off-site alert system using SMTP email protocol has been implemented and also a provision for the administrator provided...
The aim of this paper is to reduce the average neighbor discovery time and average energy consumption in self organized ad-hoc networks. The rate at which the data is transmitted is high, up to Gbps, in 60 GHz networks. These networks often use directional antenna which provides high data transmissions. But, the disadvantage of using directional antenna is, the average time consumed for discovering...
Innovations and explorations carried out continuously in power grids resulted with complex interaction with the load and power source. Utilizing the communication backbone that gives the smartness for these networks with effective electric power distribution system is proposed which reduces the power consumption from the transmission main power grid, thus providing a major solution for the energy...
In recent years digital designs have been highly automated, and the digital modulation provides more information capacity, compatibility, higher data security, better quality communications and quicker system availability with digital services. This paper proposes a QPSK module based on π/4 modulation technique. A simulative investigation on the bandwidth efficiency of the QPSK modulator has been...
In this paper, a high gain low-power up-conversion Gilbert cell mixer, designed in 180nm RF CMOS process, is proposed to realize the transmitter front-end working at 2.4 GHz frequency. The proposed mixer can convert a 100 MHz intermediate frequency (IF) signal into a 2.4 GHz RF signal, with a local oscillator power of 5 dBm at 2.3 GHz. A comparison with conventional other up-conversion mixers shows...
This paper mainly concentrate on the mechanical and RF characteristics of RF MEMS series switch. This paper proposes a kind of RF MEMS switch with a special cantilever beam section which will solve the problem of actuation voltage and residual stress. The cantilever beam section having actuation voltage of 5V with stress factor 0.96Mpa. The insertion loss of the switch is 0.1dB and return loss was...
Users and uses of internet is growing tremendously these days which causing an extreme trouble and efforts at user side to get web pages searched which are as per concern and relevant to user's requirement Generally users approach to search web pages from a large available hierarchy of concepts or use a query to browse web pages from available search engine and receive results based on search pattern...
We presents a photonic crystal fibers (PCFs) structures with unique arrangement of air holes with variation in areas. The structure has shown its superiority in communication application. However the structure also has found its application in sensor. Besides this confinement loss and normalized frequency for the proposed structures has also been studied.
This paper presents the design of a novel miniaturized dual-band band pass filter based on the composite right/left-handed (CRLH) metamaterial structure. In detail, sub wavelength resonators are realized through the zeroth order resonance (ZOR), and inverter structures are proposed to control the coupling between neighboring ZOR resonators. The Technique is validated by EM Predictions using IE3D.
In this work the design and implementation of FLC for customized servo voltage stabilizer for domestic and industrial application was proposed. Firmware for FLC for four operational modes is developed and embedded in ATmega 128 controller whereas the other work reports for fixed application. This servo voltage stabilizer uses single auto transformer and FLC controller works with closed loop feedback...
An approach to test application called transparent scan provides an opportunity to share tests among different logic blocks whose primary inputs and outputs are included in scan chains even if the blocks have different numbers of state variables. The conventional methodology suffers from problems such as high power consumption, less quality results both in terms of pattern count and fault coverage...
The pansharpening has been a wide area of interest during these days because of its applications in remote sensing, geoscience. Day by day it is going deep, vast and interesting as well. The concept arises due to the fact that data provided by most earth observation satellites such as Ikonos, geoeye, quickbird and wordview2 are composed of several channels of multispectral image and single channel...
A novel wide stop band with high attenuation in stop band dual-band micro strip band pass filter for wireless local area network products (WLAN) are designed using the concept of coupled line micro strip structure. Wireless local area network products (WLAN) operate at 2.4GHz to 2.5GHz and 5.235 GHz to 5.350 GHz bands. Finally, a new dual-band filter is designed, and it is demonstrated that good impedance...
Feature selection is an effective technique for dimensionality reduction and an essential step in successful data mining applications. It is a process of selecting a subset of features from the candidate set of features according to certain criteria. The main goal of supervised learning is finding feature subset that produces higher classification accuracy. The proposed method is to select an optimal...
SRM motors due to simple mechanical design have significant role in high speed operations and hence require faster control of rotor speed and minimized torque ripple. Proposed work uses Particle Swarm Optimization (PSO) for the tuning of the Emotional Learning controller (BELBIC). PSO is used for tuning the training coefficients of the BELBIC and maximizing the reward of the system to provide minimized...
