License Plate Recognition: An Insight to the Proposed Approach for Plate Localization and Binarization Technique
License Plate Recognition (LPR) system for vehicles is an innovative and a very challenging area for research due to the innumerous plate formats and the nonuniform outdoor illumination conditions during which images are acquired. Thus, most approaches developed, work under certain restrictions such as fixed illumination, stationary background and limited speed. Algorithms developed for LPR systems are generally composed of three significant stages: 1] localization of the license plate from an entire scene image; 2] segmentation of the characters on the plate; 3] recognition of each of the segmented characters. A simple approach for preprocessing of the images, localization and extraction phase has been described in this paper. Numerous procedures have been developed for LPR systems and are assessed in this paper taking into consideration issues like processing time, computational power and recognition rate wherever available.
A mobile monitoring and alert SMS system with remote configuration – A case study for android and the fused location provider
One of the parent´s main concerns nowadays it to know their children´s whereabouts. Some applications exist to address this issue and most of them rely on internet connection which makes the solution expensive. In this paper we present a low cost solution, based on SMS, and with the ability to remotely configure the child monitoring process. We also present the architecture and the full flowchart of the child application whenever a SMS is received. This case study uses Android and the more recent location API – the Fused Location Provider. For obvious reasons, the security issue has been a concern, which resulted in a configuration module in the child application to specify authorized senders.
Traffic Detection System Using Android
Traffic Detection System is an Android application that aims at determining the behavior of traffic in a particular location. It calculates the speed of the vehicle and the level of congestion or the amount of traffic is determined on the basis of the values of sensors. If any such obstruct found, then the driver is provided an option to send messages regarding high traffic to his/her friends. After a distinct number of repeated low speed and breaks, the location of the vehicle (latitude and longitude) send to a pre-specified contact (selected in case of traffic congestion) through an SMS. This application uses the features of the Global positioning system. The Latitude, as well as the longitude of the location where traffic jams are formed, is sent to the friends of the user. The Goggle map of the location also sends to the friends. It uses the SMS Manager a functionality of Android. The friends receiving the messages will thereby avoid taking the congested route and hence the level of traffic on the congested road will decrease, and the friends will reach the destination in comparatively less time
CORPORATE SOCIAL RESPONSIBILITY OF CHEMICAL FERTLIZER COMPANIES – A STUDY WITH SPECIAL REFERENCE TO FERTILIZERS AND CHEMICALS TRAVANCORE LIMITED (FACT)
The era of corporate organizations paying lip service to social responsibility is fast coming to an end. The recent past has seen corporate social responsibility becoming a process from a concept and also organizations deriving value from this initiative. The purpose of the present paper is to study innovative practices of CSR by Indian Corporates and also the level of CSR initiatives taken by the FACT Cochin Division. Though there are several industries in the Indian corporate sector, the Chemical industry is considered as one of the highly polluting industries. Therefore the researcher has taken a special effort to analyse the social commitment of this company with financial as well as market performance. The study mainly explores the various Corporate Social Responsibilities (CSR) of FACT Ltd. The paper examines how the Company, view and conduct their CSR activities. The study is based on secondary data collection and use of content analysis technique to assess CSR practices of Chemical Industries.
DESIGN OF AIRFOIL USING BACKPROPAGATION TRAINING WITH MIXED APPROACH
Levenberg-Marquardt back-propagation training method has some limitations associated with over fitting and local optimum problems. Here, we proposed a new algorithm to increase the convergence speed of Backpropagation learning to design the airfoil. The aerodynamic force coefficients corresponding to series of airfoil are stored in a database along with the airfoil coordinates. A feedforward neural network is created with aerodynamic coefficient as input to produce the airfoil coordinates as output. In the proposed algorithm, for output layer, we used the cost function having linear & nonlinear error terms then for the hidden layer, we used steepest descent cost function. Results indicate that this mixed approach greatly enhances the training of artificial neural network and may accurately predict airfoil profile.
