In the present scenario, reversible logic design is receiving great attention due to its abilities in reducing the power dissipation, increasing the processing speed and accommodating higher densities in integrated circuits. There is a one-to-one mapping between inputs and outputs, due to which there is no loss of information. Many researchers have shown their interest in implementing reversible logic...
The efficient application of electro-optic effect in Lithium Niobate based Mach-Zehnder Interferometer to construct a four bit priority encoder has been demonstrated. Priority encoder has an advantage over a traditional encoder that it can identify the priority of the request signals appearing at the same time. The study has been carried out by simulating the proposed device using mathematical description...
This paper extensively analyzes the effect of asymmetric source/drain doping on asymmetric underlap Dual-k spacer Fin-Field Effect Transistor (AsymD-k FinFET). The Proposed unequal doping concentration of source and drain leads to superior short-channel characteristics that alleviate the OFF-current (IOFF) of the device. Recently, high-k spacer materials are attracted much attention because introduction...
This paper presents a novel fuzzy logic based incremental conductance (IC) for maximum power point tracking (MPPT). Due to the simplicity of control algorithm, it is easier to implement, modify and tune the control rules of fuzzy controller. The proposed MPPT method provides better dynamic performance than the conventional IC MPPT method especially under rapidly changing weather conditions. The simulation...
Virtual machine migration (VMM) is one of important services is used as a tool to facilitate system maintenance, load balancing, fault tolerance, on-demand service offerings. Live VMM transfers an active Virtual Machine (VM) from one physical host to another across different data centers. It involves a sequence of operations in iteration under a specific protocol/method for migrating execution context...
A novel compact size triple-band microstrip antenna with and without fork like electromagnetic band gap (EBG) structure is proposed for wireless mobile communication system. The proposed antenna consists of two simple Y-slots, integrating with compact size fork like EBG structure. The overall dimension of the proposed antenna is 20.5 × 23.5 × 1.6 mm3. The results show that the presented antenna cover...
Social media has become an integrated part of the modern life-as-it has become one of the main instruments for sharing information, helping people, getting in touch with other people. Billions of people are using social networking websites such as Facebook, Twitter, and LinkedIn and generating huge amounts of data every day. Teaching,-particularly in higher education, has become more student-centered...
In this paper an Optimal Fractional Order proportional-integral-derivative (FOPID) controller is designed to levitate the iron ball in the air space using an electromagnetic coil. The infra-red sensor fixed on the vertical sides of the magnetic levitation system (MLS) is being helpful to sense the position of the ball. The controller enables the electromagnetic coil to maintain a specified force so...
In this paper an optimized proportional plus integral plus derivative (PID) controller is designed to control the non-minimum phase systems (NMP) with delay. The problem associated with the NMP system is the undershoot behaviour of the system caused by zeros of the right half plane and it becomes trivial as delay increases. To improve the system performance the parameters of the PID controller are...

After applying EBG structure to the proposed design, performance characteristics such as percentage bandwidth and return...
Global standards for cattle recognition, registration and traceability are being developed. However missed or swapped cattle, false insurance claims and reallocation of cattle at slaughter houses are global problems throughout the world. Previous cattle recognition approaches have their own boundaries and they are not able to provide required level of security to cattle livestock. In this paper, an...
Noise margin and delay are main concern to VLSI circuit designers along with the device scaling.

The concept of connecting group of electric vehicles (EVs) to the grid for power transaction is known as Vehicle-to-Grid (V2G). The EVs can be connected to the grid through V2G integrators and charging slots. The arrival of EVs in parking lot is time varying and random in nature and facilitating them to participate in power transaction is challenging and aggregator's responsibility. In this paper,...
