The growing apprehension regarding greenhouse gas emission accompanied by fossil fuel depletion has instigated the electrification of transportation sector. As a consequence of this Electric Vehicle (EV) has emerged as an environment friendly solution for the automobile industry. For large scale deployment of EVs development of proper charging infrastructure is indispensable. Charging stations (CS)...
Filtering of ECG signal is an essential step in ECG signal processing and analysis. Since ECG is a low amplitude biosignal, it is easily corrupted by external noises, and by the presence of other biosignals. The aim of filtering is to remove unwanted noise while preserving important characteristics of the signal. Various filtering techniques are available thus choosing the right filter for ECG denoising...
The temperature and dew point records of seven weather stations, located in India have been scrutinized under the self-organized criticality regime. The data models an almost ideal scaling behaviour as of the type of t/fα noise; with α≈1. This scaling behaviour strongly suggests the presence of self-organized criticality (SOC) behind both the signals. To draw more insight into the detailed dynamics...
This paper presents the particle swarm optimization based harmonic elimination pulse width modulation (HEPWM) technique for three-phase voltage source inverter (VSI) to reduce predominant lower order harmonics at its output. The switching strategy of power semiconductor devices of VSI decides the nature of its output voltage. In this regard, the switching strategy can be broadly classified as lower...
Recently, several protocols have been proposed to accomplish user authenticity with proper session key establishment in Global Mobility Network. Unfortunately, some of them still suffer from various security threats and high computational complexity. This article demonstrates a new enhanced two-factor authentication scheme for secure anonymous communication to mutually authenticate the communicating...
Recently, several studies have considered the use of mobile sink (MS) for data gathering in wireless sensor networks. As, it can enhance lifetime of the sensor network by distributing load among the sensors. In some delay-critical applications, a mobile sink is allowed to move along a predefined path. However, due to the predefined path and relatively slower speed of mobile sink, data gathering from...
Digital representation of biomedical images and videos has grown enormously in scope and gained importance in recent years. Preserving security and integrity in wireless transmission of biomedical images and videos is an utmost challenge. Manipulation of sensitive biomedical data in the path of transmission can mislead critical diagnosis and treatment. To overcome this, multi-level security is provided...
Detecting precise location of aircraft during the entire flight duration is a challenge in the domain of commercial aviation. Using radar and other available technology, flights operating entirely over land can be tracked easily. However, with long haul intercontinental flights, where majority of the flight path is over water bodies and out of range of radar, detecting the location of aircraft at...
This paper introduces a mars exploration robot based system that useful to explore the planet mars. Mars Rover NSU is a semi-autonomous robot that is developed based on sensors and interactive applications. The robot is capable of completing human assistant tasks, Astronaut assistance task, collecting resource from planet mars, giving a feedback of soils condition such as temperature, moisture, pH...
This Waste management is a major issue for rapidly growing megacities in developing countries. Unorganized and poor management system leads towards negative environmental impact, and lowering livability of these cities. How-ever, there are scope for integrating general people in the waste management to improve overall performance. In such context, the aim of this study is to develop and detail, a...
Spectral signature based post classification change detection approach is applied to identify the changes in Brahmaputra river along with sandbars around Kaziranga National Park in Assam, India. Landsat 5 images from 2006 to 2011 are used and the results are compared with the annual rainfall of the region to identify areas that are erosion prone. From the results it is observed that the amount of...
Handwritten character recognition is an essential part of optical character recognition domain. Bangla handwritten compound character recognition is a complex task that is challenging due to extensive size of and sheer diversity within the alphabet. The current work proposes a novel method of recognition of compound characters in Bangla language using deep convolutional neural networks (DCNN) and...
A MANET or Mobile Ad-Hoc Network is decentralized in nature and it is basically a collection of heterogeneous mobile nodes which are autonomous and can communicate among themselves over the wireless link. In this infrastructure-less network, all the nodes dynamically route the packets by themselves with help of some protocols for sending or receiving the packet information. The ZRP or Zone Routing...
Cloud services are gaining popularity with times. Service level agreement (SLA) serves a basic understanding between the clients and cloud service providers (CSP). Ensuring secured and adequate service is a basic need of the customers. In this work a set of compliance parameters for cloud service level agreement is identified. A generic rule base is designed to empower the process with an automated...
With the rapid increase in data and its complexity of configuration and deployment bring a new challenge to the research community. In this scenario, automatic Hadoop cluster deployment and management tool provide a new horizon which plays a vital role in resource and packet management in distributed environment. This paper describes a low-cost Automatic Hadoop Cluster Deployment and Management tool...
This paper reports the application of a hybrid metaheuristic — a combination of Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO) methods, in midscale thermal power dispatch problem with transmission losses. The hybrid technique applies ACO over output obtained by PSO to get an economic load dispatch (ELD) solution close to global optima. In the present study the hybrid technique...
In this paper, we propose a novel framework for expression recognition by using salient landmarks induced shape signature. Detection of effective landmarks is achieved by appearance based models. A grid is formed using the landmark points and accordingly several triangles within the grid on the basis of a nose landmark reference point are formed. Normalized shape signature is derived from grid. Stability...
Intelligent Transportation System (ITS) is integral towards envisioning a truly mobile and digital India. While existing solutions like smart vehicles and autonomous driving are inapplicable for Indian cities, transport surveys in India have provided offline solutions through GPS data. Without analytical formulations, they are prone to failure in ever-changing Indian urban landscape. This paper addresses...
In this paper, we present an approach to monitor the Italian public opinion from tweets analysis, with reference to the vaccination topic. This topic has recently become controversial, due to the disinformation about the alleged connection between autism and vaccines. Further, the Italian Ministry of Health has noticed a drop in vaccination rates, enhancing the risk of reemergence of eradicated diseases...
Text classification (TC) is a task that assigns a text to one or more classes and predefined categories. Constructing text classifiers with high accuracy is a vital task in biomedical field, given the wealth of information hidden in unlabelled documents. Because of large feature spaces, traditionally discriminative approaches, such as logistic regression and support vector machines with n-gram and...
