There by allowing resale or lending of second hand books. v Event driven software package for the database of Integrated coastal and marine area management (ICMAM). Technology : - C and Graphics Tools and Platforms : - Mat Lab 5.3 and Windows Role : - Designing, Coding and Testing Client : - Department of Ocean development (DOD), New Delhi Team Size : - 3 Description: National Institute of Oceanography (NIO, RC, Visakhapatnam) had taken up the Integrated Coastal and Marine Area Management (ICMAM) project funded by Department of Ocean Development (DOD), New Delhi. The main objective of this project is to classify the coastal waters of East Coast of India, by compiling and collecting various data sets, viz., physical, chemical, biological, microbiological, meteorological and climatilogical. The data was compiled for the stations, viz., Digha, Konark, Puri, Gopalpur, Visakhapatnam, Krishnapatnam, Pondicherry, Nagapatnam and Tuticorin. A huge database was generated for the above stations. Based on the overall information, the coastal waters will be classified which will help the state governments and pollution control boards to plan the future industries/activities along the coast. The project was successfully completed and the final reports were submitted to D.O.D in the year 2003. An event driven software package was developed for the above database. The graphical user interface (GUI) software using “C” language helps to retrieve the required parameter at a particular place/station. This is very helpful to search for the data of a particular station. The present developed software is a set of “C” language programs, linked by number of functions and user defined header files. This software is used for rapid retrieval and display of physical, chemical, biological, microbiological, meteorological and climatilogical data. Data are stored as sequential access disk files for rapid access. Programs are interactive and have graphics capability. A wide range of display and analysis outputs is available. v User interface software for Sound propagation. Technology : - C and Graphics Tools and Platforms : - Mat Lab 5.3 and Windows Role : - Designing, Implementation and Testing Client : - Naval Research Board (NRB), New Delhi Team Size : - 2 Description: The developed software “User interface for Sound propagation” is searches eigenrays (A ray connecting between the source and receiver) of infinity number of rays. This software is used for getting eigenrays using deep/shallow water sound propagation studies. This module generates MatLab files for details on ray information and ray coordinates to plot. v Estimation of Sand transport on natural beaches – A case study for Visakahapatnam beach and some simulation experiments. Technology : - C and Graphics Tools and Platforms : - Mat Lab 5.3 and Windows Role : - Designing, Coding and Testing Client : - National Thermal Power Corporation (NTPC), Visakhapatnam Team Size : - 6 Description: Estimation of annual volume of sand transport along the coast is important for civil engineering, planning and construction of coastal structures. Sand transport by wind is a major factor involving stability of beaches and backshore of some areas of interest. One of the motive forces for transporting sand along the coast is littoral current generated by wave action, and the other one is wind on naturally grinded beaches. Studies on later topic was carried out from Bagnold’s formula, present reports work, using comprehensively collected time series wind data and sand sampling during November, 1997 to November, 1998 along beach of Visakhapatnam (Mutyalammapalem-Appikonda beach stretch), east coast of India, as a case study. The basic environment input for calculation of annual transport for this method is wind data, average grain diameter of sand and length of reach perpendicular to the direction of wind (i.e., projections). Relevant formulations of mathematical equations and their algorithms and analysis of results of the numerical experiments based on available data along reaches of Visakhapatnam coast are presented. This software package was developed to calculate the sand transport on natural beaches. The present software is a set of “C” and “MatLab” language programs, linked by number of functions and user defined header files. These software routines compute time-averages of wind, D50, projections for given wind data and sediment grain-distribution of the area of interest to compute sand transport. Routines are described from a user’s point of view. The result of output reveals that the total volume of sand transport due to wind is approximately 4593 m3 / year for the entire stretch of the Visakhapatnam beach. v Image Compression Software using Singular Value Decomposition (SVD) Technique. Tools and Platforms : - Mat Lab 6.5 and Windows Role : - Guidance Client : - Andhra University, Visakhapatnam Team Size : - 5 Description: An integrated friendly-user interactive multiple Ocean Application Package has been developed utilizing the well known statistical technique called Singular Value Decomposition (SVD) to achieve image and data compression in MatLab environment. This package facilitates to assign an input file like images (BMP, JPEG, TIFF and GIF)/Data (in the form of Matrix) and automation has been made to obtain compressed image/data for a given Closeness ratio. A worked example reveals that drastic reduction in storage space in compressed image as well as data is achieved. Another interesting feature of present SVD compression technique is that a JPEG image file gains higher compression with less quality loss. v User Interface Software for Marine Acoustic Modeling. Technology : - C and Graphics Tools and Platforms : - Mat Lab 5.3 and Windows Role : - Designing, Coding and Testing Client : - Naval Research Board (NRB), New Delhi Team Size : - 5 Description: Normal mode methods have been used for many years in underwater acoustics. Several normal-mode models existed which were widely used for predicting acoustic transmission-loss in the ocean; however, each had its own problems. Typical difficulties included numerical instabilities for certain types of sound-speed profiles and failures to compute a complete set of ocean modes. In short, there was a need for a model that was robust, accurate, and efficient. In order to resolve these problems a new algorithm was developed forming the basis for the KRAKEN normal model model. Kraken was greatly extended, with options for modeling ocean environments that are range-independent, range-dependent or fully 3-dimenstional. The current version offers a specialist a vast number of options for treating ocean-acoustics problems (or more generally acousto-elastic wave guides). On the other hand, it is easy for a less sophisticated user to learn the small subset of tools needed for the common problem of transmission-loss modeling in range-independent ocean environment. This model allows the both ocean and sediment sound-speed profiles. This is very useful to Naval department.
