A MIMO antenna using dual - band planar antenna with rectangular slothas been proposed. The edge cleaving reduces the width of patch in comparison with conventional rectangular patch antenna designed at the same frequency, while its gain and radiating efficiency is noticeably improved. Measured results of the proposed antenna exhibits resonant frequency at 3.6GHz and 5.48GHz with an impedance bandwidth of 100MHz and 130MHz respectively. Further, the antenna is used as a radiating element for the design of 2-Element MIMO system. © 2019 IEEE.

Dual Band Slot Antenna for MIMO Applications

In this article, we compile the work done by various mathematicians on the topic of the fixed divisor of a polynomial. This article explains most of the results concisely and is intended to be an exhaustive survey. We present the results on fixed divisors in various algebraic settings as well as the applications of fixed divisors to various algebraic and number theoretic problems. The work is presented in an orderly fashion so as to start from the simplest case of Z, progressively leading up to the case of Dedekind domains. We also ask a few open questions according to their context, which may give impetus to the reader to work further in this direction. We describe various bounds for fixed divisors as well as the connection of fixed divisors with different notions in the ring of integervalued polynomials. Finally, we suggest how the generalization of the ring of integer-valued polynomials in the case of the ring of n × n matrices over Z (or a Dedekind domain) could lead to the generalization of fixed divisors in that setting. © 2019, Institut Camille Jordan.

Charging an Electric Vehicle wirelessly is the latest technology being developed for the electric vehicles replacing the traditional way of plugging to the supply. In this paper, authors explained how to integrate Power Line Communication along with wireless power transfer in EV. The entire system is implemented in ADS simulation software. We are adapting to magnetic resonance coupling method for wireless power transfer in EV. The overall ideology of the project is to design an innovative system which involves higher power transfer and implement smart communication system between vehicle and the grid while following the latest magnetic resonance charging standards., © 2019 The Authors. published by EDP Sciences.

In this letter, we study a few properties of Complex Conjugate Pair Sums (CCPSs) and Complex Conjugate Subspaces (CCSs). Initially, we consider an LTI system whose impulse response is one period data of CCPS. For a given input x(n), we prove that the output of this system is equivalent to computing the first order derivative ofx(n).Further, with some constraints on the impulse response, the system output is also equivalent to the second order derivative. With this, we show that a fine edge detection in an image can be achieved using CCPSs as impulse response over Ramanujan Sums (RSs). Later computation of projection for CCS is studied. Here the projection matrix has a circulant structure, which makes the computation of projections easier. Finally, we prove that CCS is shift-invariant and closed under the operation of circular cross-correlation. © 2019 IEEE.

This paper presents a graph based methodology for increasing the channel capacity of Virtual-Multiple Input Multiple Output (V-MIMO) defined over a Wireless Sensor Network (WSN). A fully connected graph mathcal G (mathcal V , mathcal E , mathcal W ) is defined for a WSN. Then, we propose a new clustering algorithm based on the Fiedler vector of the graph mathcal G which divides the sensor nodes mathcal V into twoclusters (transmitting and receiving antennas). The links between these two clusters results in V-MIMO network. Next, a Modified Maximum Spanning Tree Search algorithm (MMASTS) is proposed on V-MIMO to enhance the average channel capacity. Simulation performance of average channel capacity and uncoded Bit Error Rate (BER) are plotted using different precoding techniques like Zero Forcing (ZF) and Minimum Mean Square Error (MMSE). These are also used for comparing the performance of proposed Fiedler vector based clustering with k- means clustering. © 2019 IEEE.

A large number of advantages are offered by multi level inverters and hence a number of topologies are proposed over the years. There has been an evolution of new topologies with reduced number of switching devices. Not a single topology is enough for all the applications, so these topologies are developed with orientation based upon the application. Some topologies suites one application but do not suite well to the other application. The paper presents a comparative modelling analysis of a number of multilevel inverter topologies with reduced device count with the purpose of proposing the better options out of reduced device count topologies for economic optimization of grid interface inverter. © 2019 IEEE.

This paper proposes an idea of employing sparse reconstruction-based technique for thermal imaging defect detection. The implementation of the reconstruction technique is tested on a carbon fiber reinforced polymer test piece with artificially drilled defects and the test results are compared with the established cross correlation method. The two processes are compared in terms of defect detectability, their SNR variation with defect depth and their computation complexity. When compared with cross correlation algorithm, the technique is expected to solve memory space problems by compressing all information from large cross-correlated pulse video into a single reconstructed image as an output. Furthermore, in existing cross correlation methods, the pulse peak time shifts with defect depth. Hence, defect quantification algorithms, such as SNR calculation, require multiple frame analysis. Such algorithms are comparatively simplified in sparse reconstruction technique. This paper explores sparse reconstruction algorithm for resolving close-spaced defects. This paper further describes cross-validation method for optimization of a user parameter in sparse reconstruction method. © 1963-2012 IEEE.

In this paper a methodology is proposed for multiple distributed generation (DG) unit placement as active power source and as reactive power source in succession. The proposed work uses analytical method based upon the exact loss formula for determining optimum sizes for DG as active power source and capacitor as reactive power source. The optimization is done for loss minimization in the system. The methodology is tested for IEEE 33 bus system and results are validated with previous researches. The methodology is then extended for placement of multiple units in succession. The methodology is proved to have minimized losses to a large extent and improved voltage profile of distribution network. © 2019, Institute of Advanced Scientific Research, Inc.

Building and expansion of an efficient transportation network are essential for urban city advancement. However, tracking road development in an area is not an easy task as city planners do not always have access to credible information. A road network mapping framework is proposed which uses a random forest model for pixel-wise road segmentation. Road detection is followed by computer vision post-processing steps including Connected Component Analysis (CCA) and Hough Lines method for network extraction from high-resolution aerial images. The custom dataset used consists of images collected from an urban settlement in India. © COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only.
