Adjudgement of errors in Newton's divided difference formula for polynomial interpolation of functions ex, e2x and e3x in the interval [-1, 1]

V. P. Singh, Satish Kumar, R. B. Srivastava

Abstract

A set of three functions viz. ex, e2x, e interpolating polynomials have been obtained for each function using a computer program develope din C++ programming language. Sum of percentage errors for the functions ex, e2x and e3x in Newton’s interpolating polynomial are 0.001464412843, 0.001820947916 and 0.700182411590 respectively. This indicates that the error in the Newton’s interpolating polynomial for the exponential functions increases as its power increases.

Security Framework for National electronic Document Repository (NeDR)

Narendra K Pareek, Vikas Agrawal and Prashant Mittal

Abstract

In India alone huge vegetation is destroyed every year to manufacture paper which is used as base material for retaining copies of the documents. Other environment hazards associated with the copying industry is large consumption of toner and power. Receive infrastructures to store the documents, that too seldom been retrievable at least in the case of public authorities. The proposed solution not only overcomes these issues but also helps in better service delivery, enhanced security of documents and profitable business opportunities to SMEs particularly in rural areas. Sustainability of CSCs and Rural IT kiosk is of great concern, as long term support by government would not be possible, and these establishments/ entrepreneurs hav enhanced service delivery and increased footfalls. Such a solution has to be reliable one and information security has to be dealt on priority.


Amino acid characteristics of multifloral honey of indigenous bee apis dorsata f. and apis cerana indica from Udupi, Dakshina Kannada and Uttara Kannada districts of Karnataka

Balasubramanyam M.V., Ramesha Iyyanahalli and Jayaram, K.M.

Abstract

Multifloral honey of giant honey bee, A. dorsata (wild) and Indian hivebee,was collected from the Udupi, Dakshina Kannada and uttara Kannada districts of Karnataka and six amino acids characteristics were determined during April 2011 to March 2012. proline (P), lysine (K), glutamic acid (E), aspart in honey of wild and apiary honeybees. Proline (89.10 μ gms) was maximal from Dakshina Kannada in A. cerana honey while minimal of (83.01 μ gms) proline was found in A.dorsata honey in Udupi. Similarly A.dorsata  honey had lowest of histidine (5.97 μ gms) and highest of (7.24 μ gms) in A.cerana from Udupi and Dakshina Kannada respectively. gysine (45.12 μ gms) was maximum from Dakshina Kannada in A. cerana honey while minimum of (38.70 μ gms) lysine w honey in Udupi. Similarly A.dorsata honey had lowest of (17.16 μ gms, 15.95 μ gms and 8.52 μ gms) and highest of (20.95 μ gms,.18.13 μ gms and 10.90 μ gms) glutamic acid, aspartic acid and valine in A.cerana from Udupi and Dakshina Kannada respectively. Proline, lysine and glutamic acid of wild and apiary honey was significant at 1% (p<0.01) level, while aspartic acid, valine and histidine of honey of both species of honeybee was not significant at 1% (p<0.01) in Udupi, Dakshina Kanna and Uttara Kannada. All the six amino acids tested in A.dorsata and A.cerana displayed quantitative fluctuations in different geographical areas which are discussed in ensuing paper.


Analysis of some biochemical parameters of plants as indicator of air pollution

Preeti Pandey Pant and A.K. Tripathi

Abstract

Plants are the only living organisms which have to suffer a lot from automobile exhaust pollution and industrial pollution because they remain static at their habitat. The present experiment was done to determine the impact of air pollution on species like  angifera indica, Linn., Cassia fistula, Linn., and Terminalia arjuna, which were exposed to different air pollution load for short duration (Active biomonitoring). The biochemical parameters of the plants were studies in both the sites and compared with each other. The variation in biochemical parameters like chlorophyll, protein, soluble sugar, free amino acid, ascorbic acid, nitrate reductase, superoxide dismutase and peroxidase in the leaves were found to be pollution load dependent. The variations suggesting the activation of protective mechanism of these plants under air pollution stress, and also the plant make physiological adjustments to compensate for that environmental stress. Just by analyzing these biochemical indicators air qualities can also be assessed.
