Potassium is important to the plants for metabolic changes during flowering, and the production of floral clusters. It also promotes general plant-vigor, disease-resistance, and study growth. Hence, in this paper the concentration of potassium ion in aqueous soil samples of Anantapur area is analyzed. Combination of ISE and reference electrode is used to determine the ion activities of potassium ion in aqueous soil samples. This method is very simple and fast when compared with the other methods. The soil samples tested with the embedded system based soil analyzer.

Abstract: Man-made disasters are the outcome of lack of awareness, lack of sensitivity towards the safety measures to be taken to prevent unforeseen accidents. Large crowds always invite accidents if preventive measures are not taken with proper planning. When the number of people waits in queue before a shopping mall on a special sales day or gathering at religious functions or at a sports gallery, it is very much evident that large crowding is part of normal life. This exposes a new problem space of crowd management. Excessive crowding and poor crowd management can cost loss of precious life very easily. Hence the need for developing an automated crowd management system will be highly appreciated by the society. Crowd management involves keeping track of the crowd, the space available and balancing between the crowd and space. In this paper, we propose a prototype for counting the people as a part of developing better crowd monitoring system. The system counts people and displays the result in a user friendly interface. The system has been tested in different places and found working fine for counting people.

Abstract: The heart of democracy is voting. The heart of voting is trust that each vote is recorded and tallied with accuracy and impartiality. The accuracy and impartiality are tallied in high rate with biometric system. Among these biometric signs, fingerprint has been researched the longest period of time, and shows the most promising future in real-world applications. Because of their uniqueness and consistency over time, fingerprints have been used for identification over time. However, because of the complex distortions among the different impression of the same finger in real life, fingerprint recognition is still a challenging problem. Hence in this study, the authors are interested in designing and analysing the Electronic Voting System based on the fingerprint minutiae which is the core in current modern approach for fingerprint analysis. The new design is analysed by conducting pilot election among a class of students for selecting their representative. Various analysis predicted shows that the proposed electronic voting system resolves many issues of the current system with the help of biometric technology.

Abstract: GPS (Global Positioning System) has a variety of applications among which real-time tracking finds significance in day-to-day life. GPS tracking is defined as the measurement of object position and orientation in a given coordinate system using GPS data at different points of time. GPS data are collected from GPS receivers attached to the moving objects and these data are used for tracking objects in real-time. Researchers who work in GPS tracking need GPS databases which contain huge volume of GPS data generated by hundreds of GPS receivers. But the presently available GPS databases are owned by private players and are not available for use by the researchers. This work is an attempt to generate a database of GPS data which can be used by the researchers to develop and test GPS applications. The approach consists of three successive steps: Collecting floating car data (FCD) of each path once in a log file; refining the log file; and replaying multiple instances of several log files simultaneously after replacing some old values with new values to simulate GPS tracking. Thus a single path tracked previously can be used to produce a tracking simulation of a number of moving objects by path replaying and each and every execution of the simulation generates a set of new GPS tracking data of several moving objects. These data are stored in a database and can be used as sample data for developing and testing GPS applications.

Abstract: E-Learning, an important component of E-Education, is a novel system for communication between learners and teachers. In this paper we have tried to design an Object Oriented UML based E-Learning system for distance education of an institute with the objective to enhance the quality of teaching learning process in distance mode. The various objects participating in the system have been identified and shown by USE CASE diagrams and the object oriented development process, object to object communication among the objects, is shown by sequence diagram.

Abstract: This paper,in a sense, is a sequel to an earlier construction by T.Gnanaseelan of a graph (G, H) for any finite group G and a subgroup H using (complex) irreducible characters (See ). We construct another graph (G, H), which is structurally quite different from (G,H). However, we prove that for the special case of the sequence of subgroups Sn-1 Sn Sn+1 (where Sn is the symmetric group on n letters), (Sn, Sn-1) and (Sn+1, Sn) are indeed isomorphic.

Abstract: Retinal exudates classification and identification of diabetic retinopathy to diagnose the eyes using fundus images requires automation. This research work proposes retinal exudates classification.
Approach: Representative features are obtained from the fundus images using contextual clustering (CC) segmentation methods. The number of features obtained is two. The radial basis function (RBF) network is trained by the features. Final weights are obtained and subsequently used for testing.
Results: The presence of exudates is identified more clearly as the CC uses neighbourhood information. By knowing the outputs of RBF during testing, accurate diagnosis and prescription for treatment of the affected eyes can be done. One hundred fundus images are used for testing. The performance of RBF is 96%(48 images are classified).
Conclusion: Simulation results show the effectiveness of RBF in retinopathy classification. Very large database can be created from the fundus images collected from the diabetic retinopathy patients that can be used for future work

Abstract: Peristaltic transport of a Williamson fluid in an asymmetric channel through porous medium is studied under long wavelength and low Reynolds number assumptions. The nonlinear governing equations of the peristaltic flow are solved using perturbation method. The solution for the stream function is obtained by neglecting inertia and curvature effects. The velocity distribution, the volume flow rate and the pressure rise are also determined.
