    Aqueous corrosion behaviour of ductile iron and ductile iron containing 1 wt. pct. chromium
    (1997) Surendranathan A.O.; Hebbar, K.R.; Sudhaker Nayak, H.V.
    Ductile irons with graphite in spheroidal form enjoy the processing characteristics of grey iron and mechanical properties of steel. This paper describes the corrosion behaviour of ductile iron containing 1 wt. % chromium in sea water, dilute sulphuric acid and dilute sodium hydroxide solutions and compares with that of unalloyed ductile iron. Study is made in as-cast, annealed and cold worked (upto 28% reduction in thickness) conditions at three different temperatures. Since the alloying addition brings changes in the proportion of phases, the corrosion behaviour of the two materials studied were different, though alloying addition is small, indicating corrosion behaviour to be structure sensitive.

    Pipelined Parallel Processor to implement MD4 Message digest algorithm on Xilinx FPGA
    (1998) David S.
    The paper presents a pipelined parallel processor architecture design to implement the MD4 message digest algorithm which computes the message digest or the fingerprint of 128 bit fixed length, for any arbitrary length of input message. The processor implements the arithmetic, logic and circular shift operations by a pipelined parallel process. The architecture is designed to suit the design flexibility of the Xilinx Field Programmable Gate Arrays (FPGAs) The processor reads the message from an external RAM, 16-bit at a time and internal operations are performed with 32-bit data. The major advantage of the design is increased speed of computation and minimum hardware. The processor computes the digest with a speed approximately three times faster than the software version implemented in DSP processors.

    Chemical amplification method for the determination of atmospheric sulphur dioxide
    (1997) Pandurangappa M.; Balasubramanian N.
    A sensitive spectrophotometric method is described for the determination of trace levels of sulphur dioxide in ambient air after fixing the gas in triethanolamine (TEA) or triethanolaminemannitol absorbing solutions. The method is based on the reaction of sulphur dioxide with iodine to form iodide and after the extraction of unreacted iodine, the iodide was oxidized to iodate by bromine. The generated iodate is utilized to oxidize hydroxylamine to nitrite which produces an azo dye in the presence of p-nitroaniline and N-(l-naphthyl)ethylenediamine dihydrochloride (NEDA) in acid medium with maximum absorption at 545 nm. The system obeys Beer's law over the concentration range 0-5 μg of sulphur dioxide in a final volume of 25 ml. The relative standard deviation is 2.5% at 4 μg of sulphur dioxide (n = 10). The interference of other gaseous species were suitably overcome by the proper reaction conditions. The developed method was applied to determine low levels of sulphur dioxide generated using permeation devices and ambient levels of sulphur dioxide in the vicinity of a sulphuric acid plant.

    Assessment of heavy earth-moving machinery noise vis-à-vis routine maintenance
    (2006) Vardhan, H.; Karmakar, N.C.; Rao Y.V.
    Exposure to noise from various types of equipment/machinery has been identified as a critical health hazard for personnel working in the Indian mining industry. Heavy Earth Moving Machinery (HEMM) used in mines has been identified as a major source of noise, and several earlier investigators have proposed various types of retrofit measures on these machines to reduce noise. The present work was taken up with the objective of evaluating the noise generation characteristics of HEMM as influenced by periodic maintenance. Detailed noise measurements were carried out in a large open pit coal mine located in India. The effect of maintenance on noise production was assessed for ten dumpers and three dozers by measuring the A-weighted one-third-octave band sound pressure levels after the machines had been subjected to maintenance at the end of 300 hours, 500 hours, 750 hours and 1000 hours of use. Measurements were also carried out to assess the effect of maintaining specific HEMM systems noise characteristics at 1000 hours. Assessment of sound pressure levels at each periodic maintenance revealed major sound level reductions with 1000 hours maintenance. The data also identified the major noise generating systems in HEMM as air systems, exhaust systems, cooling systems and fuel systems. © 2006 Institute of Noise Control Engineering.
