As the penetration of wind energy to the grid is increasing drastically, the transmission line must be capable of handling large power which demands the series capacitor compensation for the lines. This can result in Sub-synchronous oscillations in the system. This paper explains the detailed mathematical modeling of a Squirrel Cage Induction Generator (SCIG) based wind farm, which is interconnected...
Quality and quantity of the power being transmitted is an important datum to utilize the full potential of the existing transmission line networks. This paper presents a STATCOM having transformerless Cascaded Multilevel Inverter(CMI) with level shifted modified Space Vector Pulse Width Modulation(SVPWM) technique that provides both reactive power compensation and harmonic reduction. Synchronous Reference...
A novel approach to performing automated water-meter reading for update of consumption information from field to the Utility office is described in this paper. The smart metering approach proposed differs from existing commercial methodologies by making use of low cost IoT hardware and smartphone app. This scheme permits both Meter Reader as well as individual domestic / industrial consumers to use...
Solar energy is slated to drive a sustainable future of clean and renewable energy sources. Efficient solar tracking is necessary to achieve acceptable power output per unit incident solar radiation from photovoltaic cells. This paper proposes a GPS based solar tracking system, which has been prototyped on the FRDM-KL25Z (based on the ARM Cortex M0+ MCU) platform by NXP. A significant part of the...
Next generation networks (NGN) are required to fulfill a stringent set of requirements which include high data rate, spectral efficiency, low out-of-band (OOB) radiation and latency. Generalized frequency division multiplexing (GFDM) is one of the schemes proposed at physical layer for NGNs. GFDM is a block-based transceiver scheme consisting of non-orthogonal subcarriers which are individually filtered...
Tree is a widely used topology for Wireless Sensor Networks (WSNs). As Time Division Multiple Access (TDMA) eliminates collisions, it is a preferred channel access mechanism. Often multiple sinks are deployed in WSNs. Use of multiple sinks provides fault tolerance and load balancing. In tree based networks, every sink becomes root of exactly one tree. When node deployment is not uniform across the...
Use of digital images has increased tremendously in medical science and with that has increased the query on authenticity of the image. Authenticity of the digital image is very important in the area of scientific research, forensic investigations, government documents, etc. With the help of powerful and user friendly image editing software like Microsoft Paint and Photoshop it became extremely easy...
Waste management in Urban Cities of India is a serious concern with growing amounts of uncollected garbage on the streets. In this paper, we present a mobile application based solution to empower the citizens to report instances of uncollected garbage and draw the attention of authorities. Our application has been successfully deployed and has seen more than a million complaints registered across...
Surface Plasmon Resonance (SPR) is a quantum optical effect that directly enables bio-molecular interactions without labeling immobilized probe molecules. It can be widely used as a biosensor to detect molecular absorption or desorption on sensor surface [1]. The phenomenon is also imperative for technologies ranging from gene assays, DNA sensing, bacteria sensing, surface controlled electro-chemical...
Water is a vital resource for life and for the economy. Nowadays, one of the most serious challenges to solve is to manage water scarcity. As the importance of water usage optimization in monetary point of view is not that pronounced, we lack the incentive to invest in implementing technologically advanced systems for organized distribution of water. This paper describes the development of a meticulous...
The monumental changes happening in present infrastructure industry can mostly be attributed to developments in Internet of Things. Developing smarter conference rooms in offices have a great scope for innovation and digital transformation. In this paper, we have developed a Smart Meeting Room (SMR) architecture and addressed various imminent issues pertaining to a meeting room environment by providing...
With increase in size of Internet of Things IoT device networks and applications, tremendous increase is witnessed in IoT data. Efficient storage and querying of this data is of major concern. This paper addresses the issue of faster query processing of this data. It presents a Log Based Method LBM to store and query IoT data in Resource Description Framework RDF format. LBM exploits skewedness in...
In the present era of modern communication network, the importance of mobile technology can't be denied at all. The requirement of high speed internet access through these mobile devices seamlessly has been increased. The growing use of IP devices in the field of mobile network has generated a great demand of network mobility. To fulfill these demands, network mobility architecture has been studied...
In this work, a new grid synchronization control strategy is developed for a single stage three phase grid coupled Photovoltaic system that employs Kalman Filter Algorithm (KF) to estimate the fundamental sinusoidal components of the Point of common connection (PCC) voltage and load current respectively. The DC-link bus capacitor voltage is regulated employing a Proportional-Integral (PI) controller...
Steganography is the art of hiding information in a medium. Steganography tends to leave little doubt about the fact that information is being hidden. In this paper an intelligent approach to image steganography is proposed. First, a key is passed using an algorithm such as Diffie-Hellman. This key is used to encrypt the text using an enhanced Caesar Cipher algorithm which provides security and is...
In the present work, the impact of Negative Capacitance (NC) effect of ferroelectric materials has been studied on Elliptical Gate All Around Junctionless Transistors by incorporating these materials as gate insulator. Landau Devonshire theory and parabolic potential approximation has been used to develop an analytical model to obtain various electrical parameters like surface potential, gate capacitance,...
The communication among connected vehicles in vehicular ad hoc network must be protected from unauthorized message injection and message alteration bymisbehaving vehicles. The proposed scheme allows only the connected authentic vehicles to disseminate message. It identifies the replay attackers, fake nodes and also the attackers that are disseminating false message as misbehaving vehicles. A certificate...
Developing a robust vehicle tracking system is an active area of study in the field of automotive tracking. Such a system is also helpful in providing support to collision avoidance, lane change instructions and merge assistance. Fast Compressive Tracking (FCT) algorithm has recently been proposed for object tracking. FCT has not been explored on vehicle tracking datasets LISA and TME Motorway. In...
