Many researches are going on in the field of optical character recognition (OCR) for the last few decades and a lot of articles have been published. Also a large number of OCR is available commercially. In this literature a review of the OCR history and the various techniques used for OCR development in the chronological order is being done.
This paper proposes the method of automating the process for switching of smart devices between different test beds using Distributed Control System (DCS). An asset maintenance application helps the maintenance personals to maintain smart devices in process industry. Using this application a maintenance operator can perform device specific maintenance activities like calibration, device configuration,...
Over the years, a lot has been done in the field of medical technology to assist the elderly and physically challenged people. One such development is the robotic wheelchair. Many designs of the same have been proposed throughout the recent past. But such models still face difficulties in covering difficult terrains like steps, etc. We propose a design of wheelchair which will be able to mimic easy...
Active Power Filters are developed for compensating the harmonics, reactive power simultaneously. The performance of shunt Active Power Filter depends on the two factors i.e., type of the controller and methods used to obtain the reference current. Generally, the type of controller used in most of the Active Power Filters is traditional PI controller or Fuzzy Logic Controller. Recently, Fault Tolerant...
Crude oil refinery is an industrial process plant where crude oil is processed and refined into more useful by-products. The crude oil is not sent directly into the distillation column, instead it is heated to a high temperature and then passed to the column. The characteristics of the refinery products are dependent on the furnace's outlet temperature and the parameters of the distillation tower...
The performance of Automatic Speech recognition system (ASR) built using close talk microphones degrades in noisy environments. AS R built using Throat Microphone (TM) speech shows relatively better performance under such adverse situations. However, some of the sounds are not well captured in TM. In this work we explore the combined use of Normal Microphone (NM) and TM features to improve the recognition...
In this paper, we deal with mobile ad-hoc networks have emerged as a major next generation wireless technology. An attack in MANET is very vulnerable for all the layers. An attack acts as a malicious node which affects the network performance. Sybil attack is one of the severe attacks in network layer which creates confusion in the routing which can be detected and prevented by an Agent. Agent can...
Usage of image processing techniques for robotic systems is essential to make robot which can perform tasks like human. In this paper a person follower robotic system is proposed using an NI Single-board Reconfigurable Input-Output (SBRIO-9632). The board has real time controller and a Field Programmable Gate Array (FPGA) device. The controller and devices are programmed using NI LabVIEW software...
In the past decade, robotic applications in human life have made significant progress. However, mobility of robots and user convenience of their control is still a challenge. Utility of robots for a physically challenged person, with practicality and ease of operation, is another issue. In this paper, a robotic solution is proposed for utilization by the physically challenged. A prototype robot is...
This paper presents a scheme for the classification of multispectral satellite images into multiple predefined land cover classes. The proposed approach results in a fully automatic classification model to assign each pixel in the image to a group of pixels based on reflectance or spectral similarity where each subset of group of pixels is called ground-truth data. The input image is preprocessed...
Last decades have witnessed a rapid growth in the development of hard er, difficult and complexity to machine metals and alloys. The use of water and abrasive in such a type of machining i.e., AWJM is one of the most recently developed nontraditional hybrid mechanical type machining in processing different kinds of hard-to-cut materials nowadays. It is an economical method for heat sensitive materials...
The presence of nonlinearities irn acoustic paths affects the performance of the acoustic channels by generating nonlinear echoes. These nonlinear echoes are cancelled by introducing a new class of nonlinear adaptive filters, derived by the adaptive combination of filters. Such filters are derived from the functional link adaptive filter (FLAF) model defined by a nonlinear input expansion and a subsequent...
The new framework proposed in this paper provides an insight into the problem of face authentication (verification) in unconstrained environment. This unconventional method extracts and represents the microstructures and local features of a given face image by greedy approach and sparse code respectively. This gives a stable and discriminative local descriptor for each patch that hinge on the local...
Voice Translator is speech to speech translation application for android mobile phone, which translates English speech to Hindi speech and vice versa. Voice Translator includes three modules, Voice Recognition, Machine Translation and Speech Synthesis. Voice Recognition module captures the voice or speech from the mobile user through speaker, identifies then converts the speech into text and then...
Most critical and major in growing technology for High Performance of demand of power & energy and an urgent problem in powering technologies. Energy optimization is an enabling power Management. The Consumption of Energy Should be ascertainable not only to Gate Level or Register Transfer (RT) Level but also to the System Level. Reducing the Energy Consumption of system not deviating the overall...
‘Efficiency’ is a booming word in the current global scenario. The paper describes such an algorithm named ‘cell zooming’ that aims at providing energy efficiency to the operating cellular network. Energy efficiency is achieved by operating some selected base stations in sleep mode. The energy consumed in sleep mode is much lesser when compared to the normal operation. Here, the performance analysis...
In this work, the radiation characteristics of the microstrip fed rectangular patch antenna is analyzed for 2.4 GHz applications. The microstrip patch antenna consists of a pair of electrically conducting layers separated by a 1.5 mm dielectric material. The RT Duroid 5880 is used as dielectric substrate and it has dielectric permittivity of 2.2. Low dielectric constant substrates are essential for...
Reliability and timely information delivery are highly concerned factors in Vehicular ad-hoc network. A better handover mechanism plays an important role in the handover process between the vehicle nodes during the vehicles on the road. Vertical handover is very much essential to ensure service continuity in Vehicular Ad-hoc network. When we compared with conventional handover decision taken by single...
In this paper, Least Squares Support Vector Machine (LS-SVM) is used for a fast and accurate estimation of the power system loading margin for multiple contingencies with reduced input features. The input variables considered are the real and reactive power demand at the load buses. The training data for the LS-SVM are generated by using the Continuation Power Flow (CPF) method. The proposed method...
