    Abstract: Extraction of shoreline incoastal zone is important for coast protection and management. This paper presents extractingthe shoreline with fusion images, which are obtained using various image fusion methods such as IHStransform, Brovey Transform, Multiplicative, Principle Component, Wavelet Resolution Merge. Artificial constructions (e.g. coastalem... Show More

    Abstract: Decision Support System for Agrotechnology Transfer (DSSAT) was calibrated and evaluated to simulate maize (zea mays L.) var. BH660 under current and future climate in Ethiopia under moist mid-highlands of Ethiopia around Ambo Zuria district. Simulations for both current and future periods were run assuming present technology, current varieties and... Show More

    Abstract: The present project was conducted to determine whether difference in stocking ratio of silver carps can affect the growth performance of mrigal and grass carp. Fingerlings of Ctenopharyndon idella, Hypophthalmicthys molitrix and Cirrhinus mrigala were stocked at the ratio of 15:45:45 and 15:45:30 in fertilized experimental pond 1 and 2 with two rep...
