A number of approaches have been developed for image steganography till date but none have used quadtree partition scheme. The quadtree partition is used to divide the image on the basis of variations among the pixel values and therefore we can identify the fine grained and coarse grained areas inside the image. It is very much comfortable and effective to hide something in the roadside scrub rather...
This paper presents a comparative study of dual material double gate junctionless transistor with the single material double gate junctionless transistor. A review of the basic modelling of the Junctionless transistor is also given in the paper. The surface potential of both structures are compared. The threshold voltage compared for both the devices shows that the single material gate has higher...
Earth features are arranged following one or many rules called spatial patterns. Around the world many features share common patterns. To discover those patterns and analyzing them through some data visualization technique can lead to a good decision supporting system. In this paper analysis and visualization model is designed for the Uttarakhand(India) region. Data like district wise population,...
In the recent few years several efforts were dedicated for mining opinions and sentiment automatically from natural language in online networking messages, news and business product reviews. In this paper, we have explored sentiment orientation considering the positive and negative sentiments using film user reviews. We applied the technique Naive Bayes' classifier.). We have performed the sentiment...
Advancement in computing technologies and increasing demand of computing resources (such as network, storage, servers, applications etc.) has made cloud computing as main computing basis for small or large IT enterprises. The enterprises which are not able to establish their own infrastructure and resources are taking help of different (Infrastructure as a Service) IaaS service providers on basis...
The D-STATCOM has been used to control the voltage to its value by exchanging reactive power with the distribution network. For a good compensation of the sag and swell, 2 management approaches, specifically the point and modulation index schemes are used. For the previous, speedy adjustment within the injected or absorbed reactive power can't be achieved. Thus, this paper proposes a DSTATCOM employing...
Analyzing the behavioral patterns to maintain the workload in cloud computing is very important. There are number of cloud data centers that have the facility to maintain this. But this paper has provided the approach for resource utilization based on two metrics, energy and cost function. This approach works within the workload which helps to understand the relationship between users and servers,...
The integration of mathematical modelling, proof of correctness and statistical software quality assurance lead to extremely high-quality software. The integration was named as cleanroom software engineering. It proof the correctness of the deliverables of each phase, Instead of the classic analysis, design, code, test, and debug cycle, the cleanroom approach suggests a different point of view. Due...
The study was intended to analyze the effect of three types of music, namely Indian classical music, Bhajan (spiritual anthem) music and rock music, on the electroencephalogram (EEG) activity for two different age groups, viz. young subjects (23–27 years) and elder subjects (40–55 years). We recorded EEG in 10 healthy elder subjects and 10 healthy young subjects at eyes closed condition during without...
Brain-computer interface (BCI) technology is communication system is rely a pathway to explore the brain activities to external world. The BCI technique make possible to monitor some physical processes that occur within the brain activity that correspond to certain forms of flickering light through stimuli. Observed a thousand of brain activities are firing instantaneous which allowed the BCI system...
Single Scattering Albedo (SSA) is one of the most important parameters in deciding the type of aerosols present in the atmosphere. This study mainly aims to study the characteristics of SSA at 388nm wavelength (UV region) at global scale using Ozone Monitoring Instrument (OMI) (level-3) data which is on board the NASA Aura. The study is carried out for the period 2014 December to 2015 November. The...
Emotion expression is an essential function for daily life that can be severely affected some psychological disorders. In this paper we have identified nine motions. We have extracted more than 20 features from natural speech. In this work database used are SAVEE(Surrey audio visual expressed emotion) and BERLIN. The overall experimental results reveals that combination of features values extracted...
Paraphrase generator tool is essential component of any NLP application. This paper presents paraphrase generator tool for Dravidian language of Kannada language using dictionary lookup approach. The paraphrase generator developed by using the morphological analyzer, dictionary lookup and morphological generator approach, generates paraphrases for a given sentence. The paraphrasing is a task that...
Air pollution has become health hazard. With the growth of industries, the air quality has now become an issue both for the environment as well to the society over the last few years. Due to the rising degradation of air quality, the need for control has risen. Artificial neural network have been applied to many environmental engineering problems and have demonstrated good degree of success in processing...
Si CMOS has been the driving potential behind tremendous achievements obtained in the field of electronics, computing and telecommunications. However there is a need to explore alternative device technologies that could somehow either complement the existing CMOS technology or replace it, as it advances it's saturation point. Graphene nanoribbon Field Effect Transistors could serve as an alternative...
Wheelchair usage in India is increasing day by day because of ageing population, road accidents and injuries etc. In case of nuclear families, the elder people those who are unable to do their regular activities without assistance, are left alone at their home. Manual propelling is difficult for aged people, so to avoid it they choose the motorized wheelchair. However, the cost of the motorized wheelchair...
LPG cylinders have become an integral part of every home. Our kitchens are occupied with LPG cylinders which help us make delicious food. But it can be dangerous and life threatening. Therefore, it requires constant vigilance to reduce the danger. The aim of this paper is to design a safety oriented system which will alert the user about any threat in the kitchen through mobile and also capable of...
In this paper Direct torque control technique of induction motor is used with different controlling techniques. These techniques are Direct Torque Control with Proportional controller, Proportional Integral controller, Fuzzy Logic controller, Neural Network and Space Vector Modulation. In all the techniques by performing experiments, I have calculated the reading of electromagnetic torque, stator...
This paper presents a high gain wearable metamaterial antenna for biomedical applications. The wide band antenna is designed such that it mimics the electrical properties of the human skin. The proposed antenna operating in the X-band (8–12 GHz) allows sensing of varying differences in dielectric properties among skin tissues over a wide band of frequency and thus, can be used for skin cancer detection...
BCI (Brain Computer Interface) can act as permanent solution and new approach of communication through which subject can communicate with the system and can directly control devices which maximizes the capability of individual. As BCI does not require for any exterior muscular activity, there it develops a possibility for a device to be regulated by the human brain (waves) by Brain Computer Interface...
