Communication is an essential part of human life which paralytic patients with locked-in syndrome are deprived of. In locked-in syndrome, the patient cannot move any of his voluntary muscles except the eyes. Taking this into consideration, the proposed system is designed to detect the face and pupil of the patient through a standard webcam using Haar cascade classifiers and Circular Hough Transform...
A compact wideband quarter-wave transformer using microstrip lines is presented. The design relies on replacing a uniform microstrip line with a multi-stage equivalent circuit. The equivalent circuit is a cascade of either T or π networks. Design equations for both types of equivalent circuits have been derived. A quarter-wave transformer operating at 1 GHz is implemented. Simulation results indicate...
Fundamental and higher order modes of C-shape patch are discussed and their comparison against the resonant modes of equivalent rectangular patch is presented. Resonant length formulation for C-shape patch at its higher order mode is proposed. The frequency calculated using the same closely agrees with the simulated frequency. A new configuration of C-shape microstrip antenna loaded with step width...
In today's high paced world where time management stands next to God, it becomes very essential to manage all our roles as well as goals, in order to complete the given task on time. The inability of an individual to do so might lead to serious consequences. At times one might feel extreme pressure and cannot stop worrying about tomorrow's job and pending deadlines. Along with this one has to also...
Today Big data is one of the most widely spoken about technology that is being explored throughout the world by technology enthusiasts and academic researchers. The reason for this is the enormous data generated every second of each day. Every webpage visited, every text message sent, every post on social networking websites, check-in information, mouse clicks etc. is logged. This data needs to be...
Pattern Structure is a generalization of Formal Concept Analysis, comprising of objects and their description forming pattern concepts. Stability is an important measure to rank such concepts. However, in relation to similarity, stability is measured by a crisp computation. In this paper, a new Game Theory based technique is proposed to compute relatively stable concepts with high similarity. It is...
Cognitive radio (CR) sense the spectrum to discover the available white spaces in it for making better utilization of spectrum and alleviates the spectrum shortage problem. While using the available spectrum, it avoids the harmful interference with licensed users or primary users (PUs). Individual spectrum sensing by CR may not be accurate due to fading and shadowing effects. Cooperative spectrum...
In many organizations huge amount of data is generated. Organizations use this data for their own benefit. Data mining extracts useful knowledge from huge data. Association rule mining is a powerful technique to find hidden patterns in large database. The limitation of mining association rules is that some sensitive patterns are revealed from sensitive rules. It is necessary to hide sensitive rules...
In this paper, a frequency reconfigurable microstrip slot antenna for S and C band of microwave application is presented. The frequency reconfiguration is achieved due to the change of current distribution on the ground plane of microstrip slot antenna. Thus, RF PIN Diode is used as switching device to change slot length for altering current distribution on the ground plane. Two rectangular slots...
This paper presents a new approach for digital Speech Steganography and watermarking in the speech signal. In the proposed approach, Quantization index modulation is applied on one of the speech signal feature called as line spectral frequency to indicate the pattern of watermark in each frame of the speech signal. Steganographic data or watermarked information is conveyed through the silence part...
This paper's objective is to present the performance comparison between Wi-Fi IEEE 802.11ac and Wi-Fi IEEE 802.11n by measuring the throughput and steaming rate of big data streaming. The performance test is divided into four scenarios, 1) data streaming to one device, 2) data streaming with different distances, 3) data streaming to multiple devices, and 4) live broadcast a big data streaming. The...
The goal of this research is to design an e-learning content for student guidance based on 4MAT and ILS theory. This paper consists of seven parts as follows. Part one covers the learning activities. Part two is analysis of the learning activity. Part three is discussion of ILS and 4MAT. Part four is implementation of e-learning subjects. Part five is the search for experts to evaluate the learning...
An unprecedented growth in the number of internet users has resulted in an increase in power consumption of the network components and auxiliary services. It is widely believed that optical switching technologies have shown great promise in terms of bandwidth offerings and consume far less energy per bit compared to its electronic counterpart. In this paper, we characterize energy consumption of multi-mode...
Large number of Sensor nodes which are distributed over a geographical area and connected via Wireless medium is called Wireless Sensor Network. Low energy consumption is a major design constraint for battery operated embedded systems such as wireless sensor networks. In order to reduce energy consumption path selection plays a major role. The proposed system Parameter Based Reliable Routing (PBRR)...
While tapping onto the mobile device capabilities for execution of resource intensive tasks, it has been proven by many studies that the local device resources are unable to completely perform the task execution. Therefore, it becomes imperative that the intra-device resources are put to productive use by offloading the jobs to a remote location for execution. However, in those settings where the...
This paper presents the design of a passive band pass filter with a single phase matrix converter (SPMC) topology used for induction heating. Proposed configuration reduces total harmonic distortion (THD) of the output voltage and therefore, enhances the fundamental output power. Here the sinusoidal pulse width signals are generated and synchronized to avoid commutation problems, occurred in matrix...
Growth of the Internet and web applications has led to vast amount of information over web. Information filtering systems such as Recommenders have become potential tools to deal with such plethora of information, help users select and provide relevant information. Collaborative Filtering is the popular approach to recommendation systems. Collaborative Filtering works on the fact that users with similar...
Circularly polarized microstrip antenna realized by cutting unequal arm length U-slot is discussed. In 2.3 GHz frequency band, it gives VSWR and axial ratio bandwidth of 9 and 4%, respectively. In the reported work, a detailed explanation about the working of circular polarized antenna in terms patch resonant modes and the equations/design procedure to realize similar antennas at different frequency...
Electrical energy is now the biggest driving force on earth. The dependence and widespread use of electricity has its equivalent pros and cons. Thus modernization of the traditional grid system in order to overcome the major setbacks is the need of hour. Making use of advanced tools and development of various applications for evolution of conventional system is the major lead for smart grid. Demand...
