Diabetic Retinopathy is an eye disorder that leads to blindness caused by damage in retina. For this reason the exact recognition of vessels become difficult. In order to overcome this difficulty and early detection of eye diseases there are various vessel segmentation techniques. This paper presents a Hybrid Neighbourhood Estimator before Filling (NEBF) with ACO which enables us to segment vessels...
JavaScript Object Notation (JSON) is a syntax for exchanging and storing data, the text data is converted in Object form and processed. The consistency and data integrity are the big challenges of payload delivery. In general, a message digest which is a cryptographic one way hash function containing a set of digits is used to protect the integrity of a data. The message digest is attached with the...
Memristor technology has tendered the new dimensions in the semiconductor technology as a potential solution to offer high density, low power, non volatile digital logic and memory functions. In this paper nano-device property of Memristor has been utilized to design an area efficient high speed full adder. In comparison to other design of logic gate and full adder, the novel full adder circuit has...
In designing synchronous circuits and memory elements, Flip-flops (FF) play an integral role. In the present era, the demand of area efficient, lesser delay, and faster devices are the major concern. This paper present the comparative study of Flip Flops in terms of area and delay. The problem of device size is very dominant today because the demand for small device size along with lesser number of...
This paper is aimed at developing a Hexagonal Patch Microstrip antenna for C Band, X Band and Ku Band Applications. This is designed using FR-4 (Lossy) substrate and validation of model is done using extensive simulations in CST MWS 2011. The proposed design is achieved using 3 steps with each step resulting in a great enhancement in the bandwidth. The proposed antenna works for all frequencies from...
The paper illustrates the contact resistance limited behavior of pentacene based organic transistor using simulation and mathematical model. The characteristic behavior of transistor is found somewhat deviated from the predicted Shockley model invariably used to predict the performance of conventional transistors. This difference is due to the existence of non-linear behavior of contacts in organic...
Arithmetic Logic Unit plays a vital role in the central processing unit of the computer system. Addition is considered to be a primary part in the ALU. Power and speed are the major parameters to be kept in mind for designing an adder. Because of carry propagation, complexity and delay gets introduced in the adder circuit due to which addition, subtraction and multiplication obtains delay in the Arithmetic...

In modern wireless communication system, antennas having low profile structure with wider bandwidth has become the most trending class of antennas. One proposed method of fulfilling the aforementioned requirements is via the use of a fractal geometry, giving rise to fractal antenna. This paper presents novel metamaterial based fractal antenna. FR4 is used as metamaterial layer. The results of return...
Software Defined Radio (SDR) is an emergent technology for future network centric operations as it can support dynamism of Mobile Adhoc Networking (MANET) waveforms through its inherent benefits of re configurability, portability and reusability. Unlike conventional radio, designing Physical layer for MANET waveform over SDR platform demands a new design approach and consequently must be tested thoroughly...
By the exponential growth of Credit Card user the fraudulent transactions also have increased dramatically. The genuine transaction and fraudulent transactions are almost similar, so it is very hard to discover a fraudulent transaction form the genuine one. In this paper we have proposed fraud detection algorithm based on Fuzzy-ID3. Intermediate nodes we split using attribute having highest information...
Cloud computing is a distributed system which gives the facilities of resource sharing and coordinates over different topographical areas. Because of its dynamic and heterogeneous nature of the virtual machine, the virtual machine scheduling is a complicated job in cloud computing. In recent past, bacterial foraging has come into views as a worldwide maximization algorithm for control and optimization...
Multicarrier pulse width modulation (MC-PWM) techniques such as Level-shifted PWM (LS-PWM) and Phase-shifted PWM (PS-PWM) are the popular methods to control the output voltage of Multilevel Inverters (MLIs). The advantage of LS-PWM techniques over PS-PWMs is that they produce better harmonic profile, but the un-equal power distribution problem of LS-PWMs imposes limitation to their usage in high power...
This paper focuses on frequency control of standalone wind-diesel system using SMES. As the inertia is small, any disturbance in the load will disturb the frequency which will cause electromechanical oscillations. The system frequency which is used to control the SMES unit is estimated by centre of inertia COI technique. SMES being a fast acting storage system can handle the electromechanical oscillations...

This paper introduces a hybrid fuzzy based PID controller to improve the performance of power system stabilization. The inadequately damped electromechanical motions in power frameworks has been an issue to power engineers for quite a while. This restrains the ability of transfer of power in transmission lines and further incites worry in the mechanical shaft of machine. Owing to large scale interconnections...
