A great deal of effort has been devoted in recent years for developing algorithms to reduce the noise that is inherent in all digital images. This paper presents a critical analysis of image noise reduction algorithms in general. Noise removal is an important task in image processing. The results of the noise removal have a strong influence on the quality of image processing techniques. The nature of the noise removal problems depends on the type of noise corrupting the images. Several techniques for noise removal are well established in the domain of image processing. This Paper presents a comparative analysis on some of the efficient image de-noising algorithms and analyses different objective image quality measurement parameters.

A study was conducted on the distribution of different forms of zinc (Zn) in soils (0–20 and 20–40 cm depths)in different blocks of Cooch Behar district, West Bengal,India. The soils of the selected areas were acidic in reaction (pH) at both the depths, ranging from 4.23 to 6.96 (0–20 cm) and 3.89 to 6.45 (20–40 cm) and having sandy to sandy loam texture. The different fractions of Zn varied among the soils of all locations. The order of different zinc fractions was: exchangeable zinc(Ex-Zn) < organic matter-bound zinc (OM-Zn) –1 at 0–20 cm depth and 0.92 kg ha–1 in the soils of Tufanganj-II at 20–40 cm depth respectively. Exch-Zn,OM-Zn, Mn-Ox-Zn and Am-Ox-Zn were positively correlated with CEC (r = 0.088, r = 0.105, r = 0.137, r = 0.103) at 0–20 cm depth, while at 20–40 cm depth, Exch-Zn, OM-Zn, Mn-Ox-Zn, Am-Ox Zn and Cry-Ox-Zn were positively correlated with CEC (r = 0.204, r = 0.168, r = 0.342, r = 0.123, r = 0.278). The influence of different soil properties on the distribution of Zn fractions in the soils was apparent from this study.Keywords

Particle swarm optimization (PSO) is a very efficient optimization tool for solving many scientific and engineering problems. In this paper, an intelligent broadcaster controlled co-operative multi-swarm PSO (IBC-MPSO) has been proposed which improves the fitness and robustness of the PSO technique. The multi-swarm approach with a novel broadcasting mechanism provides diversification in the searching and the involvement of neighborhood operator improves the exploitation of searching of the swarm. The co-operative methodology along with an intelligent broadcaster as a whole achieves good accuracy of the optimization result for the numerical problems. The efficiency of IBC-MPSO optimization technique is comprehensively evaluated for standard popular benchmark optimization problems and compared with several state-of- the-arts PSO. Further, IBC-MPSO is applied for tuning the parameters of a PID controlled both for AVR system and DC motor based system. Result of the experiments illustrates the effectiveness of the IBC-MPSO technique.Keywords

We have monitored the forest cover depletion in parts of Assam and Arunachal Pradesh over an area of 42,375 km2 in an elephant landscape falling in the Lesser Himalaya, North East India and report the results here. The US Army topographic maps (1924) and multi-date satellite images (1975, 1990, 2000 and 2009) were visually interpreted on-screen for post-classification comparison and forest cover change detection. The exercise showed continuous high loss of forest cover during the study period. A land area having 17,846.27 km2 forest in 1924 was depleted to 12,514.56 km2 by 1975, 11,861.75 km2 by 1990, 10,808.92 km2 by 2000 and 10,256.58 km2 by 2009, thereby indicating a constant decrease in forest cover by 12.59%, 1.54%, 2.48% and 1.31% respectively. The total loss in forest cover was estimated to be about 7590 km2 from 1924 to 2009. The Cellular Automata Markov Model has predicted a further likely decrease of 9007.14 km2 by 2028. In general, more districts of Assam than Arunachal Pradesh and more plains than hills faced deforestation. We have identified increasing human population and subsequent demand on the land for cultivation as major reasons for forest cover depletion.Keywords

Rural India occupies 72% of the total geographical area of the country. It is resource-rich (land, water, forest, animal, bird and fish resources and above all wide range of biodiversities), but poor in capable human resources. Rural India is spread across 650,000 villages with an average population of 700 million in 2.3 lakhs village panchayats of which 170.3million live below the poverty line with poor quality of life in all respects.

Etymologically Agribusiness means business with agricultural produce, within agriculture industry agribusiness is widely used simply as a convenient portmanteau of agriculture and business but in its truthful format agribusiness means corporate farming that integrates agricultural production, processing, marketing and use of food fiber, and by-products from plant crops and animals coupled with long distance trade, occupational specialization and urbanism. Literally, it also acts as a marker for a concerned stage of civilization.

A case study is presented here on the continued development efforts at the Bhabha Atomic Research Centre on instrumented pipeline inspection gauge for Indian Oil Corporation Limited over the last two decades. A marvel of technology involving challenges of non-destructive testing techniques, mechanical, magnetism, electronics, data processing and analysis, operational safety requirements and portability, qualifications of the tools and characterization of defects with acceptable accuracy were achieved to be at par with the internationally available tools. These tools are being extensively deployed in the field. The homegrown technology for in-line inspection has brought down the cost of the tool and that of the services per kilometre. Different technologies are now being pursued to ensure that the in-line inspection work in the country is carried out in an ‘Atmanirbhar’ way.References
