With the rapid growth of web technology, there is a huge volume of data present in the web for internet users. It also become the place for online learning and exchange ideas. The information gathering has become more important to find out what other people think about any product, service or organization. This gives an enormous growth and availability of rich-opinion data in various social media...
A wireless sensor network is comprised of self organized sensor nodes which are distributed in a particular area to collect, process and transmit the acquired data from the physical environment. Since, sensor nodes are battery powered devices with limited processing and transmission power, energy consumption is a serious issue in system designs of WSNs. The main goal of WSN is the reliable detection...
The design of planar Ultra Wide Band (UWB) band pass filter using periodic Defected Ground Structure (DGS) is presented. The filter is realized with interdigital coupled lines, stepped impedance open stub and slotted DGS. Interdigital coupled lines are used to widen the band width of the filter. Stub is to provide transmission zeros in upper and lower stop band where as DGS improves the return loss...
In computer forensics analysis, hundreds and thousands of files are usually examined. Lots of the data present in those files consists of unstructured text, and the analysis of those texts difficult to be performed by computer examiners. For that there is a need of automated methods of analysis. In particular, algorithms for clustering documents can help the discovery of new and useful knowledge from...
We have investigated a unique design of microstrip patch antenna. The design of patch consists of four different geometry cut-out having equal area. The geometry includes square, rectangle, circle and ellipse. The simulated results of the proposed antenna shows its wide application in ultra wideband region. Moreover, the designed antenna has reported a quadruple band. The reported resonating frequencies...
Social media is a biggest successful buzzword used in the recent time. Its success opened various opportunities for the developers. Developing any application requires storage of large data into databases. Many databases are available for the developers, Choosing the right one make development easier. MongoDB is a cross platform document oriented, schema-less database eschewed the traditional table...
Global Navigation Satellite Systems (GNSS) is a collection of satellite systems, which is used to locate users' positions. Radio wave propagation effects on GNSS signals play a major role in precise position, velocity and time determination. In the atmosphere, the signal is subjected to influence by ionosphere and troposphere. In the ionospheric region, the Total Electron Content (TEC) content varies,...
In this paper we compare various methods to improve the transient stability of wind farm and HVDC. Mainly it considered for fault recovery problem associated with doubly fed induction generator (DFIG) based wind farm and a static synchronous compensator (STATCOM) with high voltage direct current (HVDC) transmission.
A coupled line narrowband filter with second harmonic suppression is presented. A Novel narrow bandpass filter with sharp rejection at the lower frequency is proposed using open loop resonator. The stopband characteristics of complementary square split ring resonator (CSRR) are studied and designed to suppress the second harmonic frequency. CSRR loaded with the proposed filter for harmonic suppression...
The routing protocols in MANETs((Mobile Ad-hoc Networks), generates high cost as it depends on hop-by-hop routing which unables to provide anonymity protection to source, destination and routes.), ALERT (Anonymous Location-Based Efficient Routing Protocol) routing protocol can be used which portioned the network into hierarchical zone partition and also randomly chooses the nodes as intermediate relay...
This paper proposes a method for controlling a Robotic arm using an application build in the android platform. The android phone and raspberry piboard is connected through Wi-Fi. As the name suggests the robotic arm is designed as it performs the same activity as a human hand works. A signal is generated from the android app which will be received by the raspberry pi board and the robotic arm works...
Electromyography shows the electrical activity of the muscles of the body. EMG signals can be recorded using surface electrodes. The SEMG signals thus obtained are used for varied applications most of which contribute towards prosthetic technology and rehabilitation engineering. SEMG signals are used as control signals for robotic arm functions as well. The aim of this study is to construct a prototype...
Insulation of transformer has been an integral part of condition assessment for many years. The insulating oil playing the role of dielectric barrier as well as heat escape route especially in power transformer. Primary drawback of mineral oil is that it can present an unacceptable fire risk when it was located near to domestic hats. With silicone fluids, we can meet code requirements for fire protection...
World Wide Web (WWW) has different type of large collection of data, with available information for every single user query. Policy group or network is helpful to the person those are political scientist. They are used to understand the financial and social topics/Theory. Evaluation of policy groups requires hard and taking so much time. This process is manual including interviews and questionnaires...
Survivability is an ability of a network to withstand and recover from failures; it is one of the most important requirements of the network. This manuscript presents simple integer linear program (ILP) formulations for node-arc working capacity allocation model. This model provides 100% secure protection against link failure. The capacity utilization for network A (six-node), network B (eight-node)...
Location Based Service Applications (LBSAs) are becoming a part of our lives. Through these applications the users can interact with the physical world and get all data they want.eg; Foursquare. But it misuses it in many ways by extracting personal information of users and lead to many threats. To improve the location privacy we use the technique LocX. Here, the location and data related with it are...
In this paper, an Embedded System for Cash Deposit at ATM machine has been proposed. ATMs available nowadays facilitate services like cash withdrawal, transaction details, account balance, card to card money transfer. The proposed system will be installed in the ATM machines already available and will enable customers to deposit money into their account without going to bank. This system consists...
