    Evaluation of river regulatory measures in hughly estuary using tidal asymmetry characteristics
    (IEEE, 2006) Sivakholundu, K. M.; Kathiroli S.; Mani J. S.; Idichandy V. G.
    Tidal asymmetry has a profound effect on estuarine hydrodynamics and sedimentation pattern. The information of tidal asymmetry can be a useful tool to evaluate the flow pattern in shallow estuary and characterize the dominance of flood or ebb flow. The effects of features (like obstructions, depressions, etc.) and discharge variation in a theoretical channel section is simulated to quantify the parameters of tidal asymmetry. A set of proposed river regulatory measures in a shallow estuary (Hughly, India) was taken up for evaluation using tidal asymmetry parameters to check whether this may be used as additional tool. The indications provided (flood dominance and hence sediment importing regime) with asymmetry parameters do match with field conditions (based on bathymetry survey data). The asymmetry parameters may be put to use to evaluate the change in flood/ebb dominance in relative terms in a given section.

    Application of parametric acoustics for shallow-water near-surface geophysical investigations
    (IEEE, 2006-05) Vasudevan, Manoj; Sivakholundu, K. M.; Venkata Rao, D.; Kathiroli, S.
    Shallow-water near-surface geophysical investigations were carried out, under two different scenarios - one to assess the status of a pipeline in the West coast and the other to assess the effect of water-injection dredging in the East coast of India. In both these investigations, Parametric Sediment Echo Sounder (SES-2000), a system developed by Innomar Technologie GmbH, which makes use of the parametric acoustical effect, was used. In the former case, profiles were taken across a pipeline at regular intervals to determine whether it was buried or exposed. The parametric system produces a 2D geo-acoustic section in which the pipe is indicated by a hyperbolic curve. The exposed height or buried depth of the pipeline at a crossing is then estimated. This investigation could, also, reveal the geomorphologic changes in the immediate vicinity of the pipeline. In the latter case, parametric acoustics was utilized to provide supplementary results for the assessment of water-injection dredging. Parametric acoustic data could expose the abrupt termination of certain near-seabed layer interfaces and sediment accumulations along steep slope, quite convincingly. SES-2000 proved to be handy to investigate the near-surface sub-seabed, especially in areas where conventional or popular methods find practical difficulties to be carried out.

    Role of storytelling in learning in the context of knowledge management system
    (IIS, 2007) Surulinathi, M.; Chavan, S.B.; Devendrappa, T.M.
    Humans are telling stories since ancient, and there is a resurgence of interest in the art among today’s organizational leaders. What is new is the purposeful use of narrative to achieve a practical outcome. This paper focuses on some leading concept like learning style, learning methods, learning tools in knowledge management system. Storytelling will become a key ingredient in managing communications, education, training, innovation and sharing knowledge in the digital learning environment. Storytelling is the act of telling a story in an entertaining, impressive or dramatic way. “Audience want an unexpected gift at an unexpected time”. Adding feeling or emotion is probably most important. How do we do it? Generally we remember the feeling of the event or imagine what our characters might be feeling and then adjust our 'delivery' accordingly. This articles focused on features of storytelling and how the software facilitate to telling the story.
