The World Wide Web has grown up rapidly and beyond doubt, majority of it contains useful information. But a portion of the web has a junk data and its presence cannot be ignored. Therefore, it becomes a challenging task to retrieval systems to provide useful information to the user. Also, choice of the query plays a crucial role in retrieving documents. In this paper, we propose a model that provides...
Diagnosis of breast cancer from mammograms is a crucial task. CBIR can support radiologists in their decision to retrieve similar mammograms out of a database to compare the past cases with current case. Pectoral muscle, labels, and artifacts, present in mammograms can bias the detection procedures. So extractions of these are an essential preprocessing step in the process of CAD. In this paper, an...
Distribution static synchronous compensator (D-STACOM) has a greater importance in modern distribution level for reactive power compensation dynamically and power quality improvement. In this paper an effort has been given to design a D-STATCOM, an essential shunt Flexible AC Transmission Systems (FACTS) device using decoupled current control method for three phase three wire system to compensate...
Most of the work on voltage stability assessment of power systems has concentrated on offline studies. With advancement in Phasor Measurement Unit (PMU) technology, it is quite possible to assess voltage stability margin of real time systems in smart grid. This paper has addressed on different works going on in the area of voltage stability monitoring and control using PMU technology. The report in...
In order reduction, complex systems are approximated by comparatively lower order models by retaining the inherent features of the original systems. The main objective is to design a low order controller with lesser number of states to control the higher order system effectively. In this work, the well established balanced realization technique, with frequency weights, is applied for the order reduction...
The data analytics using big data is an upcoming field which helps us in getting quick results from structured and unstructured huge amount of data. There are many fields like healthcare, weather forecasting, education etc. where the data analytics can help us in improving the applicability and services provided thereof. In our paper we concentrate on benefits of Big Data in healthcare therein using...
The Wireless Body Area Network (WBAN) is the new arising sub-field of Wireless Sensor Networks (WSN) that made the already existing conventional healthcare methods to reach a new level of smart human monitoring. The scarcity in terms of power supply to the network makes network lifetime to be one of the main challenge for which an energy efficient routing technique is required. In this paper, an energy...
The increased usage of internet for day-to-day activities starting from scheduling a meeting to online buying has expanded the scope for planning travels online. In the current era, customers prefer e-ticketing but finding the best travel website as well as the factors determining it are of utmost importance as the travel industry offers numerous services through multiple websites and their promotions...
The effect of time and space on the biogenesis of mRNA is a matter of research interest because of reports on its potential to affect different biochemical processes. As described by Bentley(2014) and other researchers, along with co-transcriptional process, post-transcriptional events also happen quite frequently for which the splicing process is delayed and a chance of different mode of splicing...
Current conveyors are widely used to implement current mode, voltage mode and mixed mode circuits of integer order. In this paper, a fractional order system is implemented using second generation current conveyor and a fractance device i.e. an RC network. The fractional order integrator of order half is designed for various s-domain models available in literature. The proposed integrators are realized...
Cloud computing is the hottest buzzword today having enormous benefits, but there remains a number of critical problems (Security, Privacy, Interoperability, Costing, etc.) preventing their wider adoption. For each job/application, Cloud resource provisioning is a cumbersome task as a number of objectives needs to be satisfied with certain constraints. This work proposes security prioritized resource...
In this paper, a wideband directional antenna comprising of bow-tie elements is loaded with Z-type near zero index metamaterial (NZIM) unit cells to achieve high-gain and reduced beamwidth. Both the simulation and measurement results show that the proposed antenna has gain of 6.9 dBi–9.3 dBi in the operating band (4.9 GHz–7.6 GHz), with average gain enhancement of 1.5 dB compared to the reference...
This paper proposes a multilevel thresholding technique for image segmentation, using an image enhancing technique and an improvised algorithm called Half-life Constant Particle Swarm Optimization (HCPSO). The multilevel thresholding is based on Tsallis entropy. This is done so that the thresholds are optimized and thus a better segmentation can be obtained. This algorithm has been tested on various...
In the present paper, a novel multi-criterion approach has been proposed for assessing the overall health condition of the transformer oil. Twenty five transformer oil samples collected from Himachal Pradesh State Electricity Board, India were used as data samples for testing and validating the proposed technique. Five effective dissolved gases in oil samples namely hydrogen, methane, acetylene, ethylene...
This paper presents a comparative performance analysis of the control strategies for a two link planar robotic manipulator. In this work PD/PID computed torque control, filtered error approximation based adaptive control, and neural network (NN) control methods are considered for comparative performance analysis. The comparative analysis of the results demonstrates that the neural network controller...
This research relates to the estimation and analysis of solar irradiance at Indore located in the state of Madhya Pradesh central region of India having longitude 77° 50' east and latitude 22° 44' north. The incident solar irradiance energy which depends the geographical region and weather conditions. The component of irradiance depends upon variation in the global and diffuse solar radiation. In...
Alternating current motors are largely used in all industries. It is very important to protect these motors from unexpected faults and breakdowns at their incipient level so that a well trained and planned maintenance could be done properly. Various fault diagnosis techniques have been developed for last two decades viz. motor current signature analysis, vibration monitoring, thermal monitoring etc...
In multiobjective optimization problem, a substantial number of solutions generated along the Pareto front are unacceptable to the decision maker. In this paper, we propose a variation of the concept of Pareto dominance by using a penalty based Multi Objective Genetic Algorithm which attempts to obtain the nondominated set of Pareto solutions within the acceptable region for decision maker. A Relenting...
The paper presents signature analysis of large power network with Phasor Measurement Unit (PMU) signal using dynamic clustering approach. This concept may become more useful for system operators having large numbers of PMUs deployment in utility power network for observing the variations due to dynamical changes. It is well known as more numbers of PMUs are introduced in the network, there is an exponential...
