Integration of Configurable Dynamic Notification System with CSIBER Website

In this digital era every academic institution and commercial setup investments enormously in hosting and maintenance of the website which plays a critical role in the success of an organization by making it reachable across wide geographical area at any time. A carefully designed website reflects institute’s best assets and delivers tremendous first-hand information to any user at any time irrespective of his/her geographical location. To stay in market there is a constant requirement for changing the look and feel and content of the website and incorporating dynamism into the website. It is inevitable to keep the website constantly updated since it is accessible to the public. As the new website data pertaining to event information, notification etc is constantly generated and old data soon becomes obsolete, it demands for continuous manual efforts from the human resource to keep the dynamically changing data current and up-to-date. It can save tremendous amount of human effort and time, if such a task is automated which in turn enables meaningful data to be displayed on the website with very little human intervention. To facilitate this new technologies such as jQuery, JSON, angular JS etc. are emerging continuously to name a few. In the current paper, the author has proposed an algorithm for the integration of dynamic notification system with existing website of CSIBER. The algorithm is implemented in PHP and MySQL and hosted on web server employing the web hosting service availed by the organization. The dynamic module is scheduled to be executed periodically on a daily basic by the Cron utility and server-side include is dynamically created and embedded in home page. Every month’s events can be scheduled and stored in the backend database which is parsed by dynamic module and the required data is accordingly generated. As a measure towards efficiency improvement, the tool is executed once per day instead of executing it for every user request. Two options are proposed for integration, one on client-side and the second one on the server-side. The dialog displaying the notification data is rendered mobile friendly and is subject to Google’s mobile friendly test

Biosorption of Fluoride from Synthetic and Ground Water Using Chlorella vulgaris Immobilized in Calcium Alginate Beads in an Upflow Packed Bed Column

The potential of immobilized Chlorella vulgaris to remove fluoride from synthetic and real ground water samples in a fixed bed was investigated. The effect of important kinetic parameters including column bed height, feed flow rate and influent fluoride concentration of solution on fluoride removal was studied. Thomas, Yoon-Nelson, and BDST models were used to analyze the experimental data and understand the influence on biosorption performance. The models’ predictions were in good agreement with the experimental data for all the process parameters studied, indicating that the models were suitable for fixed-bed column design. Fluoride adsorption was reversible. Desorption of fluoride ions was accomplished by pumping 0.1 N HCl solution. The reusability of adsorbent was studied by subjecting column to repeated cycles of fluoride adsorption and desorption. The suitability of immobilized C. vulgaris adsorbent for fluoride removal from ground water samples of Pavagada taluk, Tumakuru district was studied in the packed column

Hybrid Security Framework for Activity Based Authentication using RSA & Genetic Algorithm

In the current information age, security has achieved a tremendous importance in e-commerce applications involving financial transactions. Non-repudiation, data integrity, data confidentiality and authenticity, have become an integral part of information security. There is a tremendous risk involved in the communication of a plain text over Internet. Cryptography offers a solution for this type of risk which is referred to as a technique of encrypting and decrypting messages in such a way that they cannot be interpreted by anybody with the exception of a sender and an intended recipient. In majority of the e-commerce based applications where security is considered to be of prime importance, a single encryption algorithm is adopted for encrypting a password and the authentication information is stored on a single database server which becomes open to risks against different computer hacks. A novel solution for this problem is to generate an individual’s personal and dynamic activities which will be hard for the attackers to guess. Further, this can be combined with distributed technology where the authentication information is distributed over geographically separated multiple servers. In this paper authors have generated an activity based distributed 3D password incorporating various activities where the authentication information is distributed over geographically separated multiple authentication servers. The key pair is generated using RSA algorithm which is encrypted using single-point cross over and mutation of bits at the extreme position. This further adds another level of security and renders the key unbreakable by an unintended user. The configuration information pertaining to the distributed environment is stored in XML file which is parsed using Microsoft's XML Parser and the activity related information is stored in different servers which is encrypted using RSA algorithm. The technique employed combines RSA algorithm with Genetic Algorithm to offer a robust hybrid security framework in a distributed environment which is difficult to guess for an unintended user

AN EFFICIENT FEATURE SELECTION AND CLASSIFICATION FOR THE CROP FIELD IDENTIFICATION: A HYBRIDIZED WRAPPER BASED APPROACH

Agricultural stakeholders are concerned about the anticipated crop productionbefore the harvest. Many countries throughout the world employ computational technique'sfor predicting yield ahead of harvest to assess a country's food security and issue warningsabout impending food shortages. This is a common method that aids strategy planners anddecision-makers, particularly in rural economies. Crop statistical models have been used totrack crop development and forecast production. The only inputs available at the field levelwill yield a prediction for a narrow region; remote sensing observations cover a broad area.They may be repeated at regular intervals, allowing for large-scale crop modelling. Cropyield prediction study necessitates a variety of production parameters and algorithms. Somealgorithms are used to determine the optimum feature subset for improved prediction, whileothers are used to determine prediction. The proposed Correlation based Sequential ForwardFeature Selection (CSFFS) is compared with the existing feature selection approaches. Theclassification with proposed feature selection attains effective accuracy in crop prediction

JSP Custom Tag for Pagination, Sorting and Filtering – A Case Study

Tag libraries have the power of reducing complex functionalities to one liners by separating out implementation part from tag declarations. Tags do hide the implementation specific tasks from the end user by making the code more readable. The frequently and widely used functionality in any application is database operations which involve lot of code repetition. Such a repeated code can be hidden behind a couple of custom tags where the end user can be concerned only with the tag usage which renders the application bug free and also aids in rapid application development. Majority of automation softwares at the minimal incorporate functionalities for interaction with repository of data . The need for quick searching of required data and retrieving subsets of data demand sorting, pagination, and filtering capabilities to be an integral part of any application. With the exponential growth in data these functionalities become mandatory to be incorporated in any application irrespective of its type and size. Further, Rich Internet Application (RIA) demands an attractive graphical user interface providing visual clues on the type of data to be entered or to be displayed. In order to cater a solution to this issue, in the current paper, the authors have designed and implemented a JSP custom tag for displaying a database table data in columns of different types such as check boxes, images, hyperlinks etc. Boolean attributes are added to the tag for enabling one or more of the features corresponding to pagination, sorting and filtering

Design and Development of Deterministic Finite Automata Parser for Querying Hardware and Software Configuration Information of Local Area Network

A typical Local Area Network (LAN) of an educational institution hosts different hardware devices and contains numerous softwares installed, serving the needs of persons from low technical expertise to high technical standards. Further as the academic curriculum is upgraded most of the existing softwares become obsolete and new softwares are installed or existing softwares are upgraded to new version to cater the needs which is a continuous process. To address such issues, a quick and reliable snapshot of the network configuration is desirable at any point of time. On many occasions the softwares with limited usage are installed only on few machines of a LAN. Thus, it proves to be a time consuming task to search the whole network for a single rarely used software. To tackle such issues the authors in the current paper have provided a first hand tool for automating the process of discovering LAN configuration, storing it persistently and querying the stored information in human language. The entire process is automated without any human intervention. The information pertaining to the hardware and software configuration is stored in a persistent Relational DataBase Management System (RDBMS) which can be manipulated by the tool automatically as the new hardware is connected to a LAN or a software configuration changes. The end user instead of querying the database directly will use the natural language, termed as Hardware Query Language (HQL) and Software Query Language (SOQL) designed by the authors, which is interfaced with RDBMS using DFA parser implemented by the authors. To implement HQL/SOQL, a finite set of symbols, words and language rules are defined which together constitute HQL/SOQL grammar. In this paper we present a deterministic finite automata (DFA) parser developed by us for parsing HQL/SOQL tokens. The state table and state diagrams are developed for different tokens of HQL/SOQL identified by us. State information is stored in a persistent database management system as a measure towards improving efficiency and extensibility. Currently, HQL/SOQL consists of only few commands and more commands will be added to HQL/SOQL command set in near future. The reports generated are exported to MS Word using Microsoft Word 12.0 object library
