A novel design of rectangular Microstrip patch antenna backed by C shaped defected ground plane (DGP) is presented. First, effect of adding a slot in ground plane on fundamental mode is studied. A parametric analysis is performed by varying the slot width and changes in current distribution is observed. From this observation, approximate equations to calculate the resonant length of C shaped slot...
In the modern world of digitization, processing of data in real time requires an increase in the operating speed of a system. The processing more often than not utilizes multiplication which is time consuming and introduces considerable amount of delay. As such, there is a need to reduce this delay and achieve faster real time processing of data. This paper proposes a novel architecture for implementation...
The Design of Novel Dual Core Photonic Crystal (DC-PCF) structure is presented in wavelength range of 1100– 1650nm. A step by step optimization design proposed and maximum optimized value of high Birefringence 10−2 at telecommunication wavelength of 1550 nm and with short coupling length of (0.15–0.5) mm can be achieved. The proposed design support single-endless transmission over a long length of...
Vehicular Ad Hoc Network (VANET) is a subgroup of mobile ad hoc network (MANET). It is an emerging new technology to exchange information between vehicles to vehicles. VANETs are considered as one of the most noticeable technologies for improving the efficiency and safety of transportation systems. VANET mainly used to exchange traffic information between the vehicles and prevent accident. In VANETs...
Nowadays growing number of popularization in the World Wide Web promotes e-learning via web. During e-learning the users can easily share, reuse, and organize the knowledge. Using the search engine the e-learners search the web pages by set of keywords. But the pages which are unrelated for our tags come frequently are the major problem nowadays. There is always a semantic gab between searching the...
Software Defined Networking (SDN) is an emerging technology to abstract the physical hardware which provides the large amount of data storage in the Software Defined Data Center (SDDC). In our proposed work, the Virtual Tenant Network (VTN) improves the scalability of network and provides the multi tenancy in it. The individual SDN controller runs in each virtual bridge in the VTN and either the same...
Rapid Evaluation-Based Feature Diminution algorithm involves finding a reduced set with the essential Feature which produces as the original set of Feature. The Feature diminution is performed by removing the irrelevant and redundant Features. The Rapid Evaluation-Based Feature Diminution algorithm (REFD) removes the irrelevancy by identifying relevant Feature to the target, and removing the rest...
Digital world is coming, were data as become big data with ever increase in large volume of digital information available in terms of text documents. This tends for data extraction, enrichment, analysis and retrieval of text documents which are in the form of unstructured nature becomes a major problem in search engine. Traditionally text documents are the source of storing our information; either...
The earth ionosphere has been a topic of innovation and great discoveries for almost century. The Indian low latitude ionosphere is characterized by large spatial and temporal variations [1]. The variations are originated from equatorial and low latitude electrodynamics that exhibits phenomena like (daytime) equatorial ionization anomaly (EIA) and night-time large scale plasma depletions known as...
Figure-Ground Segmentation simply means separating foreground from it's background. It has many applications in day to day life. Object recognition is one of the main applications of it. Extracting foreground from it's background is not an easy task. Various techniques are available for figure-ground segmentation. In this paper, a new approach is proposed to extract foreground from background. A high...
Steganography is the art of hiding data in data in an untraceable way. Main concern of steganography is hiding the existence of hidden message. Steganalysis is the art and science of detecting hidden messages from stego-systems. It also attempts to find hidden message such as the type of embedding algorithm, the length of the message, the content of the message or the secret key used from the carrier...
This paper proposes a novel Multi-band dual polarized elliptical shaped microstrip antenna cut with square and rectangular slot. The square slot in elliptical patch degenerates patch TM11 and TM21 modes into two orthogonal modes to realize multi-band characteristics. The optimization of the input impedance at degenerated resonant modes is done by the introduction of the rectangular slot to realize...
A wireless navigation mobile robot system is proposed in this paper for both path planning and trajectory execution. It should be within an indoor maze environment. The system consists of some device like a mobile robot, motion controller, visual sensor, ZigBee wireless communication device and a maze terrain to capture images of the mobile robot. The camera is used within the maze. To determine the...
Opinion mining is the process of retrieving the opinion evidences from the reviews and finding their polarity such as positive, negative. Topical term mining enhances the opinion mining in which topical terms have to be extracted along with opinion evidences. Topical terms are specific attribute or quality of a topic. This paper proposes an approach for topical term mining. It aims to assist the users...
Weproposed a Position Prediction based Multicast Routing (PPMR) for VANET with the objectives of alleviating the broadcast storm problem of multicast tree discovery and simultaneously minimizing the number of forwarding vehicles. A unicast protocol, Position Prediction based Unicast Routing (PPUR) serving as a base for our multicast protocol is also proposed. With the help of Global Positioning System...

This paper deals with the design of a pattern reconfigurable antenna for implant devices. Radiation pattern reconfiguration means the modification of the spherical distribution of the radiation pattern of the antenna. Beam steering is an application of the pattern reconfiguration. When the direction of the main lobe of radiation pattern is changed it is called beam steering. A monopole antenna is...
