Multivariate statistical techniques like Principal Component Analysis are used to interpret large and complex water quality data in Cauvery River at Srirangapatna. The data sets of 6 water quality monitoring stations which comprised of 10 water quality parameters monitored monthly over 12 years (2000-2011) are used for this study. PCA helped to identify the important water quality parameters responsible for the deterioration of water quality in river Cauvery. The main parameters included BOD, COD, TC, FC, Conductivity, TDS and Chlorides across baseline, impact and trend stations. PCA rendered a significant reduction in water quality data from 120 in each station to three or four principal components in baseline, impact and trend stations. Thus this study illustrates the significance of multivariate statistics in simplifying complex data sets of monitoring stations in river Cauvery at Srirangapatna and also helps in understanding the monitoring strategy for effective water quality management.

The Government of India concern for the environment of beaches in India surfaced in the year 1981. The concern is mainly towards the quality of beaches and the disappearance of mangroves. In common with most beaches and estuarine / deltaic zones in India, those of the Coastal Karnataka have suffered from neglect, encroachment, human dwellings, and industrial activity causing pollution of air, water and soil and mining operations to a certain extent. In the context of the deep concern about the harmful effects of the above activities, an attempt is made here to suggest a few recommendations for speedy implementation of remedial action. In this attempt individual component of the major resources, namely biological, industrial, tourism, water resources, human dwellings and minerals are analysed to gather overall impact data on the coastal eco-system as a whole.

Key words: Individual component, esturine, human dwellings, eco-system, industrial activity and biological.

1. It is emphasized that conservation plan of beaches and adjacent area including areas within the tidal reach should have proper policy backing in the direction of protection, rehabilitation and management.

2. Beaches and mangrove formations as-a-whole are vulnerable to changes drastically at certain segments. They have been indicated with a view to take early steps for correctives to be implemented.

3. Encroachment in varied forms is not uncommon all along the coastal Karnataka. The human dwellings and their unregulated activity along the No Activity Zone' have reached a stage to tell upon the quality of beaches and the estuariene banks supporting mangroves.

4. Loss of biomass along the beaches and mangrove habitats should be compensated by afforestation. This will help the locals to get their fuel needs and concurrently conservation of beach and mangrove zone.

5. Unregulated human dwellings, agricultural operations, fish farming are detrimental for conservation practices and they create repercussions and lead to the impoverishment of beaches and mangrove ecosystems and their destruction.

6. Aqua farming has become a seasonal affair in the coastal Karnataka. Their dual role is in producing paddy during monsoon and prawn farming during non-monsoon months. This regular practice has created saline lands to a certain extent.

7. Publicity and awareness among the locals has to be initiated by audio-visual methods to emphasise the importance of natural settings in their day-today life and conservation of the quality of beaches and mangroves.

8. Local people must be made to understand that by protective devices they will have the chance to get assured supply of fuel or fodder, which they can plan for.

9. Coastal areas selected or released for varied special purposes like tourism, afforestation, park system, fishing harbours, offshore disposal of industrial effluents should be notified to prevent their use for any other purposes than earmarked.

10. The responsibility for the beach management be placed at village level and the working procedures to be co-ordinated by a committee chaired by the Distrcit Administration and associated by Ecology and Environment, Forest, Revenue, water resources, Rural Development and Panchayath Raj, Fisheries, Agricutural and Public Works departments, local environmentalists. The maintenance of the quality of the beaches should be the responsibility of the local authorities with close links with the officials of the zilla Parishad.

Due to the growth of electricity demands and transactions in power markets, existing power networks need to be enhanced in order to increase their loadability. The problem of determining the best locations for network reinforcement can be formulated as a mixed discrete-continuous nonlinear optimization problem (MDCP). The complexity of the problem makes extensive simulations necessary and the computational requirement is high. An ordinal optimization (OO) technique is proposed in this paper to solve the MDCP involving two types of flexible ac transmission systems (FACTS) devices, namely static var compensator (SVC) and thyristor controlled series compensator (TCSC), for system loadability enhancement. In this approach, crude models are proposed to cope with the complexity of the problem and speed up the simulations with high alignment confidence. Test results based on a practical power system confirm that the proposed models permit the use of OO-based approach for finding good enough solutions with less computational efforts.

Exact extraction of the blood vessels of the retina is an important task in computer-aided diagnosis of retinopathy. This paper describes the development of an automatic image processing fundus and the analytical system to facilitate the diagnosis. The algorithm for the detection of the optical disc, blood vessels and exudates are investigated. The optical disc is identified by the method of the Sobel edge detector and LSR in the candidate area. Blood vessels and exudates are extracted by the method of Kirsch in different color components of the color image of the fundus. The processing results of the implemented methods are also presented. This paper also presents a new structural feature based registration function in the retinal image. The point coincident conventional methods depend largely branching angles single branching point. The feature correspondence through two images may not be unique because of the angle values like. In view of this, the record matching structure is favored. The branch structure comprises a branch point and its three neighbors master connected. The feature vector of each branch structure consists normalized angle and length of branching, that is invariant against translation, rotation, scaling, and distortion and even modest. This may considerably reduce the ill-posed nature of the pairing process, provided that the vascular pattern may be segmented. The simplicity and efficiency of the proposed method make it easy to apply alone or incorporated with other existing methods for formulating a hybrid or hierarchy scheme.
