The main objective of this paper is to design the low power consumption and less area occupied combinational circuit here we designed half adder circuit using three different logic styles: CMOS NAND gate logic, CMOS transmission gate logic, and NMOS pass transistor logic. All the circuits are simulated and compared by using Cadence Virtuoso IC 6.1.5, 180nm CMOS Technology with the supply voltage of...
With the advancement of mobile technologies and devices, a new network paradigm called “Opportunistic Networks” emerged. Opportunistic networks are based on the spontaneous response of the nodes and permanent links among the nodes almost absent. Due to self-organized nature of opportunistic networks and other diverse features, these networks have many security threats such as how to protect the data...
In today's era, technology has advanced to this extent that it can be very useful in domestic purposes. Our house is the center of our domestic life and we can control our daily activities by using technical system. Automating our house activities eases and simplifies the way of living. A house with smart control system is called Smart Home. The control system is built by using information technology...
With the growth of the internet and the increasing importance of emails in our daily lives, spams have become a common phenomenon posing serious threats, as it gives rise to undesired emails. Image spam is a type of email spam in which the textual message is embedded within an image presenting it as a picture. This paper proposes a Support Vector Machine (SVM) with Gaussian kernel based classifier...
Enabling the device-to-device (D2D) communication in the cellular network (CN) induces the problem of interference. This paper proposes a scheme of controlling the power of the D2D user equipments (DUEs) by switching D2D transmitter on the basis of receiver-sensitivity. The performance of the proposed scheme has been evaluated in slow fading environment, with the assumptions that the proximity gains,...
A novel SIW cavity based RF sensor is designed and developed for non-destructive testing (NDT) of dielectric and advanced composites at 1.5 GHz using the TE101 mode. The proposed sensor is fabricated on low cost FR-4 substrate, and excitation of fabricated sensor is done with 3.5mm SMA connectors. The material testing is performed using the cavity perturbation theory for real part of the permittivity,...
In this paper, design of broadband cylindrical cavity backed slot antenna for S-band telemetry system is presented. The antenna is designed using printed slot, excited by an open microstrip line. The slot is backed by a cylindrical cavity of reduced height 0.12 lambda. The antenna is integrated with Teflon radome for protection against environmental severities. The antenna has been designed for 2...
This paper elaborates on the hardware and software realization of a unique bi-modal robot developed for vigilance applications such as; aerial and ground navigation, dual arm manipulation and surveillance. One of the fundamental objectives was to build a lightweight ground unit which when attached to the flight unit, can be lifted easily during aerial mobility. The paper also reviews a mathematical...
Map matching is an important part of map routing in modern transportation applications. In the map matching process, the effect of two main components, i.e. (i) the features of road networks, and (ii) the design aspects of geolocation services, is still not well understood. In this paper, using a combination of probabilistic analysis and simulations we study the effects of the above factors on the...
Congestion management is one of the most significant issues for secure and reliable system operations in a deregulated electricity market. This paper presents an effective approach for optimal allocation and optimal sizing of Thyristor Controlled Series Compensator (TCSC) to reduce the congestion in day-ahead power market. The proposed optimization approach is based on a factor called ‘Active Power...
Contingency is one of the most important issues in deregulated electricity market. Generator rescheduling or integration of FACTS devices are the most common techniques for mitigating the contingencies in modern power system. Recently major concern is given for renewable energy generation system. In this paper, renewable energy like wind farm (WF) generation is used for maximizing the profit as well...
In a deregulated electricity market, bidding is a complex task because of generation and demand uncertainty. Recently major concern is given for maximizing the profit of the customers. Therefore, bidding is very important work for Independent System Operator (ISO) to maximize the profit of the market participant. In this paper, optimal bidding strategy of supplier under congested system has been proposed...
Life seems incomplete without Internet these days. People of all age group are using Internet very frequently in their daily lives. Kids are equally participating in the use of Internet without supervision of adults as most of the parents are too busy in their work to look after their kids all the time. Where there are many advantages of Internet on the other end the other side of it may be harmful...
This paper presents a method for automatic detection of a suspicious object in public places (like railway station, airports, bus stand etc). The suspicious object will be carried by a person in the scene. An object area is extracted using background subtraction. For selecting an object of interest a unique label has been assigned to all the objects. For labeling of objects, connected component labeling...
Present work focuses on the development of thermoelectric aluminum-doped ZnO (Al:ZnO) and NiO thin films Pulsed Laser deposition technique. XRD and Hall studies were carried out to study the structural and electrical properties of the prepared thin films. The thermoelectric studies were carried out on these films using in-house developed thermoelectric measurement set-up. The Seebeck coefficient and...
This paper reviews the maximum efficiency technique of powering electric and hybrid vehicles using an intelligent Inductive Power Transfer (IPT) system. The need for compensation techniques followed by a mathematical model to determine circuit parameters for efficient power transfer is presented. This is followed by discussing the concept of an intelligent charging station using the concept of Internet...
To make efficient use of the resources, node discovery in opportunistic networks is very important because of short communication range of the devices. Encounters are uncertain in opportunistic networks and it is difficult to determine the occurrence of next encounter. So it is essential to have an efficient node discovery mechanism in opportunistic networks to make most out of short duration of encounters...
High throughput is the crucial parameter of the adaptive filters. Here, we present an adaptive block finite impulse response (FIR) filter with high throughput using the concept of distributed arithmetic (DA). In the proposed work, block processing is applied to the adaptive filters that has helped in improving the throughput. In this paper, computation of partial products of filter output takes place...
In this paper, a compact waveguide monopulse comparator at Ka-band for monopulse tracking is presented. Simulated results show a bandwidth of nearly 6% for a return loss of better than 10 dB, an isolation of better than 40 dB between the ports, and a null depth better than 40 dB. There is an imbalance of +0.1/-0.8 dB and 1° in magnitude and phase respectively at the output ports.
For stability and good efficiency of any system the controlling of that system at different loading condition is an important factor.
